Tax Havens: International Tax Avoidance and Evasion

Summary
The federal government loses both individual and corporate income tax revenue from the shifting
of profits and income into low-tax countries, often referred to as tax havens. The revenue losses
from this tax avoidance and evasion are difficult to estimate, but some have suggested that the
annual cost of offshore tax abuses may be around $100 billion per year. International tax
avoidance can arise from large multinational corporations who shift profits into low-tax foreign
subsidiaries or wealthy individual investors who set up secret bank accounts in tax haven
countries.
Recent actions by the Organization for Economic Cooperation and Development (OECD) and the
G-20 industrialized nations have targeted tax haven countries, focusing primarily on evasion
issues. The recently adopted HIRE Act (P.L. 111-147) included a number of anti-evasion
provisions, and P.L. 111-226 included foreign tax credit provisions. Some of these proposals, and
some not adopted, are in the American Jobs and Closing Loopholes Act (H.R. 4213); the Stop Tax
Haven Abuse Act (S. 506, H.R. 1265); draft proposals by the Senate Finance Committee; two
other related bills, S. 386 and S. 569; the Bipartisan Tax Fairness and Simplification Act (S.
3018); and proposals by President Obama.
Multinational firms can artificially shift profits from high-tax to low-tax jurisdictions using a
variety of techniques, such as shifting debt to high-tax jurisdictions. Since tax on the income of
foreign subsidiaries (except for certain passive income) is deferred until repatriated, this income
can avoid current U.S. taxes and perhaps do so indefinitely. The taxation of passive income
(called Subpart F income) has been reduced, perhaps significantly, through the use of “hybrid
entities” that are treated differently in different jurisdictions. The use of hybrid entities was
greatly expanded by a new regulation (termed “check-the-box”) introduced in the late 1990s that
had unintended consequences for foreign firms. In addition, earnings from income that is taxed
can often be shielded by foreign tax credits on other income. On average very little tax is paid on
the foreign source income of U.S. firms. Ample evidence of a significant amount of profit shifting
exists, but the revenue cost estimates vary from about $10 billion to $60 billion per year.
Individuals can evade taxes on passive income, such as interest, dividends, and capital gains, by
not reporting income earned abroad. In addition, since interest paid to foreign recipients is not
taxed, individuals can also evade taxes on U.S. source income by setting up shell corporations
and trusts in foreign haven countries to channel funds. There is no general third party reporting of
income as is the case for ordinary passive income earned domestically; the IRS relies on qualified
intermediaries (QIs) who certify nationality without revealing the beneficial owners. Estimates of
the cost of individual evasion have ranged from $40 billion to $70 billion.
Most provisions to address profit shifting by multinational firms would involve changing the tax
law: repealing or limiting deferral, limiting the ability of the foreign tax credit to offset income,
addressing check-the-box, or even formula apportionment. President Obama’s proposals include a
proposal to disallow overall deductions and foreign tax credits for deferred income and
restrictions on the use of hybrid entities. Provisions to address individual evasion include
increased information reporting and provisions to increase enforcement, such as shifting the
burden of proof to the taxpayer, increased penalties, and increased resources. Individual tax
evasion is the main target of the HIRE Act, the proposed Stop Tax Haven Abuse Act, and the
Senate Finance Committee proposals; some revisions are also included in President Obama’s
plan.

Tax Havens: International Tax Avoidance and Evasion

Introduction
The federal government loses both individual and corporate income tax revenue from the shifting
of profits and income into low-tax countries. The revenue losses from this tax avoidance and
evasion are difficult to estimate, but some have suggested that the annual cost of offshore tax
abuses may be around $100 billion per year.1 International tax avoidance can arise from wealthy
individual investors and from large multinational corporations; it can reflect both legal and illegal
actions.
Tax avoidance is sometimes used to refer to a legal reduction in taxes, whereas evasion refers to
tax reductions that are illegal. Both types are discussed in this report, although the dividing line is
not entirely clear. A multinational firm that constructs a factory in a low-tax jurisdiction rather
than in the United States to take advantage of low foreign corporate tax rates is engaged in
avoidance, whereas a U.S. citizen who sets up a secret bank account in the Caribbean and does
not report the interest income is engaged in evasion. There are, however, many activities,
particularly by corporations, that are often referred to as avoidance but could be classified as
evasion. One example is transfer pricing, where firms charge low prices for sales to low-tax
affiliates but pay high prices for purchases from them. If these prices, which are supposed to be at
arms-length, are set at an artificial level, then this activity might be viewed by some as evasion,
even if such pricing is not overturned in court because evidence to establish pricing is not
available.
Most of the international tax reduction of individuals reflects evasion, and this amount has been
estimated to range from about $40 billion to about $70 billion a year.2 This evasion occurs in part
because the United States does not withhold tax on many types of passive income (such as
interest) paid to foreign entities; if U.S. individuals can channel their investments through a
foreign entity and do not report the holdings of these assets on their tax returns, they evade a tax
that they are legally required to pay. In addition, individuals investing in foreign assets may not
report income from them.
Corporate tax reductions arising from profit shifting have also been estimated. As discussed
below, estimates of the revenue losses from corporate profit shifting vary substantially, ranging
from about $10 billion to about $60 billion.
In addition to differentiating between individual and corporate activities, and evasion and
avoidance, there are also variations in the features used to characterize tax havens. Some
restrictive definitions would limit tax havens to those countries that, in addition to having low or
non-existent tax rates on some types of income, also have such other characteristics as the lack of
transparency, bank secrecy and the lack of information sharing, and requiring little or no
economic activity for an entity to obtain legal status. A definition incorporating compounding
factors such as these was used by the Organization for Economic Development and Cooperation
(OECD) in their tax shelter initiative. Others, particularly economists, might characterize as a tax
haven any low-tax country with a goal of attracting capital, or simply any country that has low or

non-existent taxes. This report addresses tax havens in their broader sense as well as in their
narrower sense.
Although international tax avoidance can be differentiated by whether it is associated with
individuals or corporations, whether it is illegal evasion or legal avoidance, and whether it arises
in a tax haven narrowly defined or broadly defined, it can also be characterized by what measures
might be taken to reduce this loss. In general, revenue losses from individual taxes are more
likely to be associated with evasion and more likely to be associated with narrowly defined tax
havens, while corporate tax avoidance occurs in both narrowly and broadly defined tax havens
and can arise from either legal avoidance or illegal evasion. Evasion is often a problem of lack of
information, and remedies may include resources for enforcement, along with incentives and
sanctions designed to increase information sharing, and possibly a move towards greater
withholding. Avoidance may be more likely to be remedied with changes in the tax code.
Several legislative proposals have been advanced that address international tax issues. President
Obama has proposed several international corporate tax revisions which relate to multinational
corporations, including profit shifting, as well as individual tax evasion. Some of the provisions
relating to multinationals had earlier been included in a bill introduced in the 110th Congress by
Chairman Rangel of the Ways and Means Committee (H.R. 3970). Major revisions to corporate
international tax rules are also included in S. 3018, a general tax reform act introduced by
Senators Wyden and Gregg, and provisions that address techniques used by corporations to
reduce taxes are included in pending legislation, the American Jobs and Closing Loopholes Act
(H.R. 4213) passed by the House on May 28, 2010.
The Senate Permanent Subcommittee on Investigations has been engaged in international tax
investigations since 2001, holding hearings proposing legislation.3 In the 111th Congress, the Stop
Tax Haven Abuse Act, S. 506, was introduced by the chairman of that committee, Senator Levin,
with a companion bill, H.R. 1265, introduced by Representative Doggett. The Senate Finance
Committee also has circulated draft proposals addressing individual tax evasion issues. A number
of these anti-evasion provisions (including provisions in President Obama’s budget outline) have
been adopted in the Hiring Incentives to Restore Employment (HIRE) Act, P.L. 111-147. S. 386,
introduced by Chairman Leahy of the Senate Judiciary Committee, would expand the money-
laundering provisions to include tax evasion and provide additional funding for the tax division of
the Justice Department. S. 569, also introduced by Chairman Levin, would impose requirements
on the states for determination of beneficial owners of corporations formed under their laws. This
proposal has implications for the potential use of incorporation in certain states as a part of an
international tax haven plan.
The first section of this report reviews what countries might be considered tax havens, including a
discussion of the Organization for Economic Development and Cooperation (OECD) initiatives
and lists. The next two sections discuss, in turn, the corporate profit-shifting mechanisms and
evidence on the existence and magnitude of profit shifting activity. The following two sections
provide the same analysis for individual tax evasion. The report concludes with overviews of
alternative policy options and a summary of specific legislative proposals.

Tax Havens: International Tax Avoidance and Evasion

Where Are the Tax Havens?
There is no precise definition of a tax haven. The OECD initially defined the following features
of tax havens: no or low taxes, lack of effective exchange of information, lack of transparency,
and no requirement of substantial activity.4 Other lists have been developed in legislative
proposals and by researchers. Also, a number of other jurisdictions have been identified as having
tax haven characteristics.
Formal Lists of Tax Havens
The OECD created an initial list of tax havens in 2000. A similar list was used in S. 396,
introduced in the 110th Congress, which would treat firms incorporated in certain tax havens as
domestic companies; the only difference between this list and the OECD list was the exclusion of
the U.S. Virgin Islands from the list in S. 396. Legislation introduced in the 111th Congress to
address tax haven abuse (S. 506, H.R. 1265) uses a different list taken from IRS court filings, but
has many countries in common. The definition by the OECD excluded low- tax jurisdictions,
some of which are OECD members, that were thought by many to be tax havens, such as Ireland
and Switzerland. These countries were included in an important study of tax havens by Hines and
Rice.5 GAO also provided a list.6
Table 1 lists the countries that appear on various lists, arranged by geographic location. These tax
havens tend to be concentrated in certain areas, including the Caribbean and West Indies and
Europe, locations close to large developed countries. There are 50 altogether.

eliminated because they had higher tax rates.
St. Kitts may also be referred to as St. Christopher. The Channel Islands are sometimes listed as a group and
sometimes Jersey and Guernsey are listed separately. S. 506 and H.R. 1245 specifical y mention Jersey, and also

e. Not included in OECD’s “gray” list as of August 17, 2009; currently on the OECD “white” list. Note that
the “gray” list is divided into countries that are tax havens and countries that are other financial centers.
The latter classification includes three countries listed in Table 1 (Luxembourg, Singapore, and Switzerland)
and five that are not (Austria, Belgium, Brunei, Chile, and Guatemala). Of the four countries moved from
the “black” to the “gray” list, one, Costa Rica, is in Table 1 and three, Malaysia, Uruguay and the Philippines
are not.
Developments in the OECD Tax Haven List
The OECD list, the most prominent list, has changed over time. Nine of the countries in Table 1
did not appear on the earliest OECD list. These countries not appearing on the original list tend to
be more developed larger countries and include some that are members of the OECD (e.g.,
Switzerland and Luxembourg).
It is also important to distinguish between OECD’s original list and its blacklist. OECD
subsequently focused on information exchange and removed countries from a “blacklist if they
agree to cooperate.” OECD initially examined 47 jurisdictions and identified a number as not
meeting the criteria for a tax haven; it also initially excluded six countries with advance
agreements to share information (Bermuda, the Cayman Islands, Cyprus, Malta, Mauritius, and
San Marino). The 2000 OECD blacklist included 35 countries; this list did not include the six
countries eliminated due to advance agreement. The OECD had also subsequently determined
that three countries should not be included in the list of tax havens (Barbados, the Maldives, and
Tonga). Over time, as more tax havens made agreements to share information, the blacklist
dwindled until it included only three countries: Andorra, Liechtenstein, and Monaco.
A study of the OECD initiative on global tax coordination by Sharman, also discussed in a book
review by Sullivan, argues that the reduction in the OECD list was not because of actual progress
towards cooperation so much as due to the withdrawal of U.S. support in 2001, which resulted in
the OECD focusing on information on request and not requiring reforms until all parties had

signed on.7 This analysis suggests that the large countries were not successful in this initiative to
rein in on tax havens. A similar analysis by Spencer and Sharman suggests little real progress has
been made in reducing tax haven practices.8
Interest in tax haven actions has increased recently. The scandals surrounding the Swiss bank
UBS AG (UBS) and the Liechtenstein Global Trust Group (LGT), which led to legal actions by
the United States and other countries, focused greater attention on international tax issues,
primarily information reporting and individual evasion.9 The credit crunch and provision of
public funds to banks has also heightened public interest. The tax haven issue was revived
recently with a meeting of the G20 industrialized and developing countries that proposed
sanctions, and a number of countries began to indicate commitments to information sharing
agreements.10
The OECD currently has three lists: a “white list” of countries implementing an agreed-upon
standard, a “gray” list of countries that have committed to such a standard, and a “black” list of
countries that have not committed. On April 7, 2009, the last four countries on the “black” list,
which were countries not included on the original OECD list—Costa Rica, Malaysia, the
Philippines, and Uruguay—were moved to the “gray” list.11 The gray list includes countries not
identified as tax havens but as “other financial centers.” According to news reports, Hong Kong
and Macau were omitted from the OECD’s list because of objections from China, but are
mentioned in a footnote as having committed to the standards; they also noted that a “recent
flurry of commitments brought 11 jurisdictions, including Austria, Liechtenstein, Luxembourg,
Singapore, and Switzerland into the committed category.”12 As of September 3, 2010, only nine
countries appeared on the gray list for tax havens and four appeared as financial centers.13
Many countries that were listed on the OECD’s original blacklist protested because of the
negative publicity and many now point to having signed agreements to negotiate tax information
exchange agreements (TIEA) and some have negotiated agreements. The identification of tax
havens can have legal ramifications if laws and sanctions are contingent on that identification, as
is the case of some current proposals in the United States and of potential sanctions by
international bodies.

Tax Havens: International Tax Avoidance and Evasion

Other Jurisdictions With Tax Haven Characteristics
Criticisms have been made by a range of commentators that many countries are tax havens or
have aspects of tax havens and have been overlooked. These jurisdictions include major countries
such as the United States, the UK, the Netherlands, Denmark, Hungary, Iceland, Israel, Portugal,
and Canada. Attention has also been directed at three states in the United States: Delaware,
Nevada, and Wyoming. Finally there are a number of smaller countries or areas in countries, such
as Campione d’Italia, an Italian town located within Switzerland, that have been characterized as
tax havens.
A country not on the list in Table 1, but which is often considered a tax haven, especially for
corporations, is the Netherlands, which allows firms to reduce taxes on dividends and capital
gains from subsidiaries and has a wide range of treaties that reduce taxes.14 In 2006, for example,
Bono and other members of the U2 band moved their music publishing company from Ireland to
the Netherlands after Ireland changed its tax treatment of music royalties.15
Some have identified the United States and the United Kingdom as having tax haven
characteristics. Luxembourg Prime Minister Jean-Claude Junker urged other EU member states to
challenge the United States for tax havens in Delaware, Nevada, and Wyoming.16 One website
offering offshore services mentions, in their view, several overlooked tax havens which include
the United States, United Kingdom, Denmark, Iceland, Israel, and Portugal’s Madeira Island.17
(Others on their list and not listed in Table 1 were Hungary, Brunei, Uruguay, and Labuan
[Malaysia]).18 In the case of the United States the article mentions the lack of reporting
requirements and the failure to tax interest and other exempt passive income paid to foreign
entities, the limited liability corporation which allows a flexible corporate vehicle not subject to
taxation, and the ease of incorporating in certain states (Delaware, Nevada, and Wyoming).
Another website includes in its list of tax havens Delaware, Wyoming, and Puerto Rico, along
with other jurisdictions not listed in Table 1: the Netherlands, Campione d’Italia, a separate
listing for Sark (identified as the only remaining “fiscal paradise”), the United Kingdom, and a
coming discussion for Canada.19 Sark is an island country associated with Guernsey, part of the
Channel Islands, and Campione d’Italia is an Italian town located within Switzerland.
The Economist reported a study by a political scientist experimenting with setting up sham
corporations; the author succeeded in incorporating in Wyoming and Nevada, as well as the
United Kingdom and several other places.20 Michael McIntyre discusses three U.S. practices that

Tax Havens: International Tax Avoidance and Evasion

aid international evasion: the failure to collect information on tax exempt interest income paid to
foreign entities, the system of foreign institutions that act as qualified intermediaries (see
discussion below) but do not reveal their clients, and the practices of states such as Delaware and
Wyoming that allow people to keep secret their identities as stockholder or depositor.21
In a meeting in late April 2009, Eduardo Silva, of the Cayman Islands Financial Services
Association, claimed that Delaware, Nevada, Wyoming, and the United Kingdom were the
greatest offenders with respect to, among other issues, tax fraud. He suggested that Nevada and
Wyoming were worse than Delaware because they permit companies to have bearer shares, which
allows anonymous ownership. A U.S. participant at the conference noted that legislation in the
United States, S. 569, would require disclosure of beneficial owners in the United States.22
In addition, any country with a low tax rate could be considered as a potential location for shifting
income to. In addition to Ireland, three other countries in the OECD not included in Table 1 have
tax rates below 20%: Iceland, Poland, and the Slovak Republic.23 Most of the eastern European
countries not included in the OECD have tax rates below 20%.24
The Tax Justice Network probably has the largest list of tax havens, and includes some specific
cities and areas.25 In addition to the countries listed in Table 1, they include in the Americas and
Caribbean, New York and Uruguay; in Africa, Mellila, Sao Tome e Principe, Somalia, and South
Africa; in the Middle East and Asia, Dubai, Labuan (Malaysia), Tel Aviv, and Taipei; in Europe,
Alderney, Belgium, Campione d’Italia, City of London, Dublin, Ingushetia, Madeira, Sark,
Trieste, Turkish Republic of Northern Cyprus, and Frankfurt; and in the Indian and Pacific
oceans, the Marianas. The only county listed in Table 1 and not included in their list was Jordan.
Methods of Corporate Tax Avoidance
U.S. multinationals are not taxed on income earned by foreign subsidiaries until it is repatriated to
the U.S. parent as dividends, although some passive and related company income that is easily
shifted is taxed currently under anti-abuse rules referred to as Subpart F. (Foreign affiliates or
subsidiaries that are majority owned U.S. owned are referred to as controlled foreign
corporations, or CFCs, and many of these related firms are wholly owned.) Taxes on income that
is repatriated (or, less commonly, earned by branches and taxed currently) are allowed a credit for
foreign income taxes paid. (A part of a parent company treated as a branch is not a separate entity
for tax purposes, and all income is part of the parent’s income.)
Foreign tax credits are limited to the amount of tax imposed by the United States, so that they, in
theory, cannot offset taxes on domestic income. This limit is imposed on an overall basis,
allowing excess credits in high-tax countries to offset U.S. tax liability on income earned in low-
tax countries, although separate limits apply to passive and active income. Other countries either
employ this system of deferral and credit or, more commonly, exempt income earned in foreign
jurisdictions. Most countries have some form of anti-abuse rules similar to Subpart F.

Tax Havens: International Tax Avoidance and Evasion

If a firm can shift profits to a low-tax jurisdiction from a high-tax one, its taxes will be reduced
without affecting other aspects of the company. Tax differences also affect real economic activity,
which in turn affects revenues, but it is this artificial shifting of profits that is the focus of this
report.26
Because the United States taxes all income earned in its borders as well as imposing a residual tax
on income earned abroad by U.S. persons, tax avoidance relates both to U.S. parent companies
shifting profits abroad to low-tax jurisdictions and the shifting of profits out of the United States
by foreign parents of U.S. subsidiaries. In the case of U.S. multinationals, one study suggested
that about half the difference between profitability in low-tax and high-tax countries, which could
arise from artificial income shifting, was due to transfers of intellectual property (or intangibles)
and most of the rest through the allocation of debt.27 However, a study examining import and
export prices suggests a very large effect of transfer pricing in goods (as discussed below).28
Some evidence of the importance of intellectual property can also be found from the types of
firms that repatriated profits abroad following a temporary tax reduction enacted in 2004; one-
third of the repatriations were in the pharmaceutical and medicine industry and almost 20% in the
computer and electronic equipment industry.29
Allocation of Debt and Earnings Stripping
One method of shifting profits from a high-tax jurisdiction to a low-tax one is to borrow more in
the high-tax jurisdiction and less in the low-tax one. This shifting of debt can be achieved without
changing the overall debt exposure of the firm. A more specific practice is referred to as earnings
stripping where either debt is associated with related firms or unrelated debt is not subject to tax
by the recipient. As an example of the former earnings stripping method, a foreign parent may
lend to its U.S. subsidiary. Alternatively, an unrelated foreign borrower not subject to tax on U.S.
interest income might lend to a U.S. firm.
The U.S. tax code currently contains provisions to address interest deductions and earnings
stripping. It applies an allocation of the U.S. parent’s interest for purposes of the limit on the
foreign tax credit. The amount of foreign source income is reduced when part of U.S. interest is
allocated and the maximum amount of foreign tax credits taken is limited, a provision that affects
firms with excess foreign tax credits.30 There is no allocation rule, however, to address deferral,
so that a U.S. parent could operate its subsidiary with all equity finance in a low-tax jurisdiction
and take all of the interest on the overall firm’s debt as a deduction. A bill introduced in 2007
(H.R. 3970) by Chairman Rangel of the Ways and Means Committee would introduce such an
allocation rule, so that a portion of interest and other overhead costs would not be deducted until

the income is repatriated.31 This provision is also included in President Obama’s proposals for
international tax revision.
While allocation-of-interest approaches could be used to address allocation of interest to high-tax
countries in the case of U.S. multinationals, they cannot be applied to U.S. subsidiaries of foreign
corporations. To limit the scope of earnings stripping in either case, the United States has thin
capitalization rules. (Most of the United States’ major trading partners have similar rules.) A
section of the Internal Revenue Code (163(j)) applies to a corporation with a debt-to-equity ratio
above 1.5 to 1 and with net interest exceeding 50% of adjusted taxable income (generally taxable
income plus interest plus depreciation). Interest in excess of the 50% limit paid to a related
corporation is not deductible if the corporation is not subject to U.S. income tax. This interest
restriction also applies to interest paid to unrelated parties that are not taxed to the recipient.
The possibility of earnings stripping received more attention after a number of U.S. firms
inverted, that is, arranged to move their parent firm abroad so that U.S. operations became a
subsidiary of that parent. The American Jobs Creation Act (AJCA) of 2004 addressed the general
problem of inversion by treating firms that subsequently inverted as U.S. firms. During
consideration of this legislation there were also proposals for broader earnings stripping
restrictions as an approach to this problem that would have reduced the excess interest
deductions. This general earnings stripping proposal was not adopted. However, the AJCA
mandated a Treasury Department study on this and other issues; that study focused on U.S.
subsidiaries of foreign parents and was not able to find clear evidence on the magnitude.32
An noted in the Treasury’s mandated study, there is relatively straightforward evidence that U.S.
multinationals allocate more interest to high-tax jurisdictions, but it is more difficult to assess
earnings stripping by foreign parents of U.S. subsidiaries, because the entire firm’s accounts are
not available. The Treasury study focused on this issue and used an approach that had been used
in the past of comparing these subsidiaries to U.S. firms. The study was not able to provide
conclusive evidence about the shifting of profits out of the United States due to high leverage
rates for U.S. subsidiaries of foreign firms but did find evidence of shifting for inverted firms.
Transfer Pricing
The second major way that firms can shift profits from high-tax to low-tax jurisdictions is
through the pricing of goods and services sold between affiliates. To properly reflect income,
prices of goods and services sold by related companies should be the same as the prices that
would be paid by unrelated parties. By lowering the price of goods and services sold by parents
and affiliates in high-tax jurisdictions and raising the price of purchases, income can be shifted.
An important and growing issue of transfer pricing is with the transfers to rights to intellectual
property, or intangibles. If a patent developed in the U.S. is licensed to an affiliate in a low-tax
country income will be shifted if the royalty or other payment is lower than the true value of the
license. For many goods there are similar products sold or other methods (such as cost plus a
markup) that can be used to determine whether prices are set appropriately. Intangibles, such as
new inventions or new drugs, tend not to have comparables, and it is very difficult to know the

Treaties
, November 2007.

Tax Havens: International Tax Avoidance and Evasion

royalty that would be paid in an arms-length price. Therefore, intangibles represent particular
problems for policing transfer pricing.
Investment in intangibles is favorably treated in the United States because costs, other than
capital equipment and buildings, are expensed for research and development, which is also
eligible for a tax credit. In addition, advertising to establish brand names is also deductible.
Overall these treatments tend to produce an effective low, zero, or negative tax rate for overall
investment in intangibles. Thus, there are significant incentives to make these investments in the
United States. On average, the benefit of tax deductions or credits when making the investment
tend to offset the future taxes on the return to the investment. However, for those investments that
tend to be successful, it is advantageous to shift profits to a low-tax jurisdiction, so that there are
tax savings on investment and little or no tax on returns. As a result, these investments can be
subject to negative tax rates, or subsidies, which can be significant.
Transfer pricing rules with respect to intellectual property are further complicated because of cost
sharing agreements, where different affiliates contribute to the cost.33 If an intangible is already
partially developed by the parent firm, affiliates contribute a buy-in payment. It is very difficult to
determine arms-length pricing in these cases where a technology is partially developed and there
is risk associated with the expected outcome. One study found some evidence that firms with cost
sharing arrangements were more likely to engage in profit shifting.34
Contract Manufacturing
When a subsidiary is set up in a low-tax country and profit shifting occurs, as in the acquisition of
rights to an intangible, a further problem occurs: this low-tax country may not be a desirable
place to actually manufacture and sell the product. For example, an Irish subsidiary’s market may
be in Germany and it would be desirable to manufacture in Germany. But to earn profits in
Germany with its higher tax rate does not minimize taxes. Instead the Irish firm may contract
with a German firm as a contract manufacturer, who will produce the item for cost plus a fixed
markup. Subpart F taxes on a current basis certain profits from sales income, so the arrangement
must be structured to qualify as an exception from this rule. There are complex and changing
regulations on this issue.35
Check-the-Box, Hybrid Entities, and Hybrid Instruments
Another technique for shifting profit to low-tax jurisdictions was greatly expanded with the
“check-the-box” provisions. These provisions were originally intended to simplify questions of
whether a firm was a corporation or partnership. Their application to foreign circumstances
through the “disregarded entity” rules has led to the expansion of hybrid entities, where an entity

33 The Treasury Department recently issued new proposed regulations relating to cost sharing arrangements. See
Treasury Decision 9441, Federal Register, vol. 74, No. 2, January 5, 2009, pp. 340-391. These rules include a periodic
adjustment which would, among other aspects, examine outcomes. See “Cost Sharing Periodic Payments Not
Automatic, Officials Say,” Tax Notes, February 23, 2009, p. 955.

can be recognized as a corporation by one jurisdiction but not by another. For example, a U.S.
parent’s subsidiary in a low-tax country can lend to its subsidiary in a high-tax country, with the
interest deductible because the high-tax country recognizes the firm as a separate corporation.
Normally, interest received by the subsidiary in the low-tax country would be considered passive
or “tainted” income subject to current U.S. tax under Subpart F. However, under check-the-box
rules, the high-tax corporation can elect to be disregarded as a separate entity, and thus from the
perspective of the United States there is no interest income paid because the two are the same
entity. Check-the-box and similar hybrid entity operations can also be used to avoid other types of
Subpart F income, for example from contract manufacturing arrangements. According to Sicular,
this provision, which began as a regulation, has been effectively codified, albeit temporarily.36
Hybrid entities relate to issues other than Subpart F. For example, a reverse hybrid entity can be
used to allow U.S. corporations to benefit from the foreign tax credit without having to recognize
the underlying income. As an example, a U.S. parent can set up a holding company in a county
that is treated as a disregarded entity, and the holding company can own a corporation that is
treated as a partnership in another foreign jurisdiction. Under flow through rules, the holding
company is liable for the foreign tax and, because it is not a separate entity, the U.S. parent
corporation is therefore liable, but the income can be retained in the foreign corporation that is
viewed as a separate corporate entity from the U.S. point of view. In this case, the entity is
structured so that it is a partnership for foreign purposes but a corporation for U.S. purposes.37
In addition to hybrid entities that achieve tax benefits by being treated differently in the United
States and the foreign jurisdiction, there are also hybrid instruments that can avoid taxation by
being treated as debt in one jurisdiction and equity in another.38
Cross Crediting and Sourcing Rules for Foreign Tax Credits
Income from a low-tax country that is received in the United States can escape taxes because of
cross crediting: the use of excess foreign taxes paid in one jurisdiction or on one type of income
to offset U.S. tax that would be due on other income. In some periods in the past the foreign tax
credit limit was proposed on a country-by-country basis, although that rule proved to be difficult
to enforce given the potential to use holding companies. Foreign tax credits have subsequently
been separated into different baskets to limit cross crediting; these baskets were reduced from
nine to two (active and passive) in the American Jobs Creation Act of 2004 (P.L. 108-357).
Because firms can choose when to repatriate income, they can arrange realizations to maximize
the benefits of the overall limit on the foreign tax credit. That is, firms that have income from
jurisdictions with taxes in excess of U.S. taxes can also elect to realize income from jurisdictions
with low taxes and use the excess credits to offset U.S. tax due on that income. Studies suggest

Tax Havens: International Tax Avoidance and Evasion

that between cross crediting and deferral, U.S. multinationals typically pay virtually no U.S. tax
on foreign source income.39
This ability to reduce U.S. tax due to cross crediting is increased, it can be argued, because
income that should be considered U.S. source income is treated as foreign source income, thereby
raising the foreign tax credit limit. This includes income from U.S. exports which is U.S. source
income, because a tax provision (referred to as the title passage rule) allows half of export income
to be allocated to the country in which the title passes. Another important type of income that is
considered foreign source and thus can be shielded with foreign tax credits is royalty income
from active business, which has become an increasingly important source of foreign income. This
benefit can occur in high-tax countries because royalties are generally deductible from income.
(Note that the shifting of income due to transfer pricing of intangibles, advantageous in low-tax
countries, is a different issue.) Interest income is another type of income that may benefit from
this foreign tax credit rule.
Since all of this income arises from investment in the United States, one could argue that this
income is appropriately U.S. source income, or that, failing that, it should be put in a different
foreign tax credit basket so that excess credits generated by dividends cannot be used to offset
such income. Two studies, by Grubert and by Grubert and Altshuler, have discussed this sourcing
rule in the context of a proposal to eliminate the tax on active dividends.40 In that proposal, the
revenue loss from exempting active dividends from U.S. tax would be offset by gains from taxes
on royalties.
In addition to these general policy issues, there are numerous other narrower techniques that
might be used to enhance foreign tax credits; a number of these are the focus of pending
legislation in H.R. 4213, the American Jobs and Loophole Closing Act.

as a reference point, are the remaining G-7 countries that are also among the United States’ major
trading partners. They account for 32% of pre-tax profits and 38% of rest-of-world gross
domestic product. The second group of countries are larger countries from Table 1 (with GDP of
at least $10 billion), plus the Netherlands, which is widely considered a tax conduit for U.S.
multinationals because of their holding company rules. These countries account for about 30% of
earnings and 5% of rest-of-world GDP. The third group of countries are smaller countries listed in

than 1% of rest-of-world GDP.
As indicated in Table 2, income to GDP ratios in the large G-7 countries range from 0.2% to
2.6%, the latter reflecting in part the United States’ relationships with some of its closest trading
partners. Overall, this income as a share of GDP is 0.6%. Outside the United Kingdom and
Canada, they are around 0.2% to 0.3% and do not vary with country size (Japan, for example, has
over twice the GDP of Italy). Note also that Canada and the United Kingdom have also appeared
on some tax haven lists and the larger income shares could partially reflect that.42

Tax Havens: International Tax Avoidance and Evasion

Evidence of profit shifting has been presented in many other studies. Grubert and Altshuler report
that profits of controlled foreign corporations in manufacturing relative to sales in Ireland are
three times the group mean.43 GAO reported higher shares of pretax profits of U.S. multinationals
than of value added, tangible assets, sales, compensation or employees in low-tax countries such
as Bermuda, Ireland, the UK Caribbean, Singapore, and Switzerland.44 Martin Sullivan reports
the return on assets for 1998 averaged 8.4% for U.S. manufacturing subsidiaries, but with returns
of 23.8% in Ireland, 17.9% in Switzerland, and 16.6% in the Cayman Islands.45 More recently, he
noted that of the 10 countries that accounted for the most foreign multinational profits, the five
countries with the highest manufacturing returns for 2004 (the Netherlands, Bermuda, Ireland,
Switzerland, and China) all had effective tax rates below 12% while the five countries with lower
returns (Canada, Japan, Mexico, Australia, and the United Kingdom) had effective tax rates in
excess of 23%.46 A number of econometric studies of this issue have been done.47
Estimates of the Cost and Sources of Corporate Tax Avoidance
There are no official estimates of the cost of international corporate tax avoidance, although a
number of researchers have made estimates, nor are there official estimates of the individual tax
gap.48 In general, the estimates are not reflected in the overall tax gap estimate. The magnitude of
corporate tax avoidance has been estimated through a variety of techniques and not all are for
total avoidance. Some address only avoidance by U.S. multinationals and not by foreign parents
of U.S. subsidiaries. Some focus only on a particular source of avoidance.
Estimates of the potential revenue cost of income shifting by multinational corporations varies
considerably, with estimates as high as $60 billion. The only study by the IRS in this area is an
estimate of the international gross tax gap (not accounting for increased taxes collected on audit)
related to transfer pricing based on audits of returns. They estimated a cost of about $3 billion,
based on examinations of tax returns for 1996-1998.49 This estimate would reflect an estimate not
of legal avoidance, but of non-compliance, and for reasons stressed in the study has a number of

limitations. One of those is that an audit does not detect all non-compliance, and it would not
detect avoidance mechanisms which are, or appear to be, legal.
Some idea of the potential magnitude of the revenue lost from profit shifting by U.S.
multinationals might be found in the estimates of the revenue gain from eliminating deferral. If
most of the profit in low-tax countries has been shifted there to avoid U.S. tax rates, the projected
revenue gain from ending deferral would provide an idea of the general magnitude of the revenue
cost of profit shifting by U.S. parent firms. The Joint Committee on Taxation projects the revenue
gain from ending deferral to be about $11 billion in FY2010.50 This estimate could be either an
overstatement or an understatement of the cost of tax avoidance. It could be an overstatement
because some of the profits abroad accrue to real investments in countries that have lower tax
rates than the United States and thus do not reflect artificial shifting. It could be an
understatement because it does not reflect the tax that could be collected by the United States
rather than foreign jurisdictions on profits shifted to low-tax countries. For example, Ireland has a
tax rate of 12.5% and the United States a 35% rate, so that ending deferral (absent behavioral
changes) would only collect the excess of the U.S. tax over the Irish tax on shifted revenues, or
about two-thirds of lost revenue.
The Administration’s estimates for ending deferral are slightly larger, over $14 billion.51 Altshuler
and Grubert estimate for 2002 that the corporate tax could be cut to 28% if deferral were ended,
and based on corporate revenue in that year the gain is about $11 billion.52 That year was at a low
point because of the recession; if the share remained the same, the gain would be around $13
billion for 2004 and $26 billion for 2007. All of these estimates are based on tax data.
Researchers have looked at differences in pretax returns and estimated the revenue gain if returns
were equated. This approach should provide some estimates of the magnitude of overall profit-
shifting for multinationals, whether through transfer pricing, leveraging, or some other technique.
Martin Sullivan, using Commerce Department data, estimates that, based on differences in pre-
tax returns, the cost for 2004 was between $10 billion and $20 billion. Sullivan subsequently
reports an estimated $17 billion increase in revenue loss from profit shifting between 1999 and
2004, which suggests that earlier number may be too small.53 Sullivan suggests that the growth in
profit shifting may be due to check-the-box. Christian and Schultz, using rate of return on assets
data from tax returns, estimated $87 billion was shifted in 2001, which, at a 35% tax rate, would
imply a revenue loss of about $30 billion.54 As a guide for potential revenue loss from avoidance,

in profits is artificially shifted abroad. If all of that income were subject to U.S. tax, it would result in a gain of $26
billion for 2004. Sullivan acknowledges that there are many difficulties in determining the revenue gain. Some of this
income might already be taxed under Subpart F, some might be absorbed by excess foreign tax credits, and the
effective tax rate may be lower than the statutory rate. Sullivan concludes that an estimate of between $10 billion and
$20 billion is appropriate. Altshuler and Grubert suggest that Sullivan’s methodology may involve some double
counting; however, their own analysis finds that multinationals saved $7 billion more between 1997 and 2002 due to
check the box rules. Some of this gain may have been at the cost of high-tax host countries rather than the United
States, however. See Rosanne Altshuler and Harry Grubert, “Governments and Multinational Corporations in the Race

these estimates suffer from two limits. The first is the inability to determine how much was
shifted out of high-tax foreign jurisdictions rather than the United States, which leads to a range
of estimates. At the same time, if capital is mobile, economic theory indicates that the returns
should be lower, the lower the tax rate. Thus the results could also understate the overall profit
shifting and the revenue loss to the United States.
Pak and Zdanowicz examined export and import prices, and estimated that lost revenue due to
transfer pricing of goods alone was $53 billion in 2001.55 This estimate should cover both U.S.
multinationals and U.S. subsidiaries of foreign parents, but is limited to one technique. Clausing,
using regression techniques on cross-country data, which estimated profits reported as a function
of tax rates, estimated that revenues of over $60 billion are lost for 2004 by applying a 35% tax
rate to an estimated $180 billion in corporate profits shifted out of the United States.56 She
estimates that the profit shifting effects are twice as large as the effects from shifts in actual
economic activity. This methodological approach differs from others which involve direct
calculations based on returns or prices and is subject to the econometric limitations with cross-
country panel regressions. In theory, however, it had an overall of coverage of shifting (that is
both outbound by U.S. parents of foreign corporations and inbound by foreign parents of U.S.
corporations and covering all techniques).
Clausing and Avi-Yonah estimate the revenue gain from moving to a formula apportionment
based on sales that is on the order of $50 billion per year because the fraction of worldwide
income in the United States is smaller than the fraction of worldwide sales.57 While this estimate
is not an estimate of the loss from profit shifting (since sales and income could differ for other
reasons) it is suggestive of the magnitude of total effects from profit shifting. A similar result was
found by another study that applied formula apportionment based on an equal weight of assets,
payroll, and sales.58
It is very difficult to develop a separate estimate for U.S. subsidiaries of foreign multinational
companies because there is no way to observe the parent firm and its other subsidiaries. Several
studies have documented that these firms have lower taxable income and that some have higher
debt to asset ratios than domestic firms. There are many other potential explanations these
differing characteristics, however, and domestic firms that are used as comparisons also have
incentives to shift profits when they have foreign operations. No quantitative estimate has been
made.59 However some evidence of earnings stripping for inverted firms was found.60

Importance of Different Profit Shifting Techniques
Some studies have attempted to identify the importance of techniques used for profit shifting.
Grubert has estimated that about half of income shifting was due to transfer pricing of intangibles
and most of the remainder to shifting of debt.61 In a subsequent study, Altshuler and Grubert find
that multinationals saved $7 billion more between 1997 and 2002 due to check the box rules.62
Some of this gain may have been at the cost of high-tax host countries rather than the United
States, however.
Some of the estimates discussed here conflict with respect to the source of profit shifting. The
Pak and Zdanowich estimates suggest that transfer pricing of goods is an important mechanism of
tax avoidance, while Grubert suggests that the main methods of profit shifting are due to leverage
and intangibles. The estimates for pricing of goods may, however, reflect errors, or money
laundering motives rather than tax motives. Much of the shifting was associated with trade with
high-tax countries; for example, Japan, Canada, and Germany accounted for 18% of the total.63 At
the same time, about 14% of the estimate reflected transactions with countries that appear on tax
haven lists: the Netherlands, Taiwan, Singapore, Hong Kong, and Ireland.
Some evidence that points to the importance of intangibles and the associated profits in tax haven
countries can be developed by examining the sources of dividends repatriated during the
“repatriation holiday” enacted in 2004.64 This provision allowed, for a temporary period,
dividends to be repatriated with an 85% deduction, leading to a tax rate of 5.25%. The
pharmaceutical and medicine industry accounted for $99 billion in repatriations or 32% of the
total. The computer and electronic equipment industry accounted for $58 billion or 18% of the
total. Thus these two industries, which are high tech firms, accounted for half of the repatriations.
The benefits were also highly concentrated in a few firms. According to a recent study, five firms
(Pfizer, Merck, Hewlett-Packard, Johnson & Johnson, and IBM) are responsible for $88 billion,
over a quarter (28%) of total repatriations.65 The top 10 firms (adding Schering-Plough, Du Pont,
Bristol-Myers Squibb, Eli Lilly, and PepsiCo) accounted for 42%. The top 15 (adding Procter and

Methods of Avoidance and Evasion by Individuals
Individual evasion of taxes may take different forms, and they are all facilitated by the growing
international financial globalization and ease of making transactions on the Internet. Individuals
can purchase foreign investments directly (outside the United States), such as stocks and bonds,
or put money in foreign bank accounts and simply not report the income (although it is subject to
tax under U.S. tax law). There is little or no withholding information on individual taxpayers for
this type of action. They can also use structures such as trusts or shell corporations to evade tax
on investments, including investments made in the United States, which may take advantage of
U.S. tax laws that exempt interest income and capital gains of non-residents from U.S. tax. Rather
than using withholding or information collection the United States largely relies on the Qualified
Intermediary (QI) program where beneficial owners are not revealed. To the extent any
information gathering from other countries is done it is through bilateral information exchanges
rather than multilateral information sharing. The European Union has developed a multilateral
agreement but the United States does not participate.
Tax Provisions Affecting the Treatment of Income by Individuals
The ability of U.S. persons (whether firms or individuals) to avoid tax on U.S. source income that
they would normally be subject to arises from U.S. rules that do not impose withholding taxes on
Congressional Research Service
19

Tax Havens: International Tax Avoidance and Evasion

many sources of income. In general interest and capital gains are not subject to withholding.
Dividends, non-portfolio interest (such as interest payments by a U.S. subsidiary to its parent),
capital gains connected with a trade or business, and certain rents are subject to tax, although
treaty arrangements widely reduce or eliminate the tax on dividends. In addition, even when
dividends are potentially subject to a withholding tax, new techniques have developed to
transform, through derivatives, those assets into exempt interest.66
The elimination of tax on interest income was unilaterally initiated by the United States in 1984,
and other countries began to follow suit.67 Currently, fears of capital flight are likely to keep
countries from changing this treatment. However, it has been accompanied with a lack of
information reporting and lack of information sharing that allows U.S. citizens, who are liable for
these taxes, to avoid them whether on income invested abroad or income invested in the United
States channeled through shell corporations and trusts. Citizens of foreign countries can also
evade the tax, and the U.S. practice of not collecting information contributes to the problem.
Based on actual tax cases, Guttenberg and Avi-Yonah describe a typical way that U.S. individuals
can easily evade tax on domestic income through a Cayman Islands operation using current
technology with little expense with current technology. The individual, using the Internet, can
open a bank account in the name of a Cayman corporation that can be set up for a minimal fee.
Money can be electronically transferred without any reporting to tax authorities, and investments
can be made in the United States or abroad. Investments by non-residents in interest bearing
assets and most capital gains are not subject to a withholding tax in the United States.68
In addition to corporations, foreign trusts can be used to accomplish the same approach. Trusts
may involve a trust protector who is an intermediary between the grantor and the trustees, but
whose purpose may actually be to carry out the desires of the grantor. Some taxpayers argue that
these trusts are legal but in either case they can be used to protect income from taxes, including
those invested in the United States, from tax, while retaining control over and use of the funds.
Limited Information Reporting Between Jurisdictions
In general, the international taxation of passive portfolio income by individuals is easily subject
to evasion because there is no multilateral reporting of interest income. Even in those cases where
bilateral information sharing treaties, referred to as Tax Information Exchange Agreements
(TIEAs) are in place, they have limits. As pointed out by Avi-Yonah most of these agreements are
restricted to criminal matters, which are a minor part of the revenues involved and pose difficult
issues of evidence. Also, these agreements sometimes require that the activities related to the
information being sought constitute crimes in both countries which can be a substantial hurdle in
cases of tax evasion. The OECD has adopted a model agreement with the “dual criminality”
requirements.69 TIEAs usually allow for information only upon request, requiring the United

States and other countries to identify the potential tax evaders in advance and they do not override
bank secrecy laws.
In some cases the countries themselves have little or no information of value. One article, for
example, discussing the possibility of an information exchange agreement with the British Virgin
Islands, a country with more than 400,000 registered corporations, where laws require no
identification of shareholders or directors, and require no financial records, noted: “Even if the
BVI signs an information exchange agreement, it is not clear what information could be
exchanged.”70
U.S. Collection of Information on U.S. Income and Qualified
Intermediaries

Under the QI program the United States itself does not require U.S. financial institutions to
identify the true beneficiaries of interest and exempt dividends. The IRS has set up a QI program
in 2001, under which foreign banks that received payments certify the nationality of their
depositors and reveal the identity of any U.S. citizens.71 However, although QIs are supposed to
certify nationality,72 apparently some rely on self certification.73 They are also subject to audit.
However, UBS, the Swiss bank involved in a tax abuse scandal that helped clients set up offshore
plans, was a QI, and that event has raised some questions about the QI program.
A non-qualified intermediary must disclose the identity of its customers to obtain the exemption
for passive income such as interest and or the reduced rates arising from tax treaties, but there are
also questions about the accuracy of disclosures.
The HIRE Act, P.L. 111-147, included some provisions strengthening the rules affecting qualified
intermediaries, although the projected revenue gain was quite small (less than $1 billion per year)
relative to projected costs (discussed below).
European Union Savings Directive
The European Union, in its savings directive, has developed among its members an option of
either information reporting or a withholding tax. The reporting or withholding option covers the
member countries as well as some other countries. Three states, Austria, Belgium, and
Luxembourg, have elected the withholding tax. While this multilateral agreement aids these
countries’ tax administration, the United States is not a participant.

Tax Havens: International Tax Avoidance and Evasion

Estimates of the Revenue Cost of Individual Tax
Evasion

A number of different approaches have been used to estimate corporate tax avoidance, however,
all of these approaches rely on data reported on assets and income. For individual evasion,
estimates are much more difficult because the initial basis of the estimate is the amount of assets
held abroad whose income is not reported to the tax authorities. In addition to this estimate, the
expected rate of return and tax rate are needed to estimate the revenue cost.
Guttentag and Avi-Yonah estimate a value of $50 billion in individual tax evasion, based on an
estimate of holdings by high net worth individuals invested outside the United States at $1.5
trillion.74 Using a rate of return of 10% and a tax rate of approximately one-third, they obtain an
estimate of $50 billion. They also summarize two other estimates in 2002 of $40 billion for the
international tax gap by the IRS and $70 billion by an IRS consultant.
To the extent that the earnings are interest, the 10% rate of return may be too high, while if it is
dividends and capital gains, the tax rate is too high. Using a tax rate of 15% (currently applicable
to capital gains and dividends) would lead to about $23 billion. In the case of equity investments,
if a third of the return is in dividends and half of capital gains is never realized, the tax rate would
be 10% or about $15 billion assuming the 10% return. During 2002 and beginning in 2011,
however, the tax rate on capital gains and dividends is 20%, indicating a loss of $20 billion rather
than $15 billion. For interest, since investors can earn tax free returns in the neighborhood of 4%
to 5% on domestic state and local bonds, to yield a 5% after-tax return at a 35% tax rates would
require a pre-tax yield of about 7.7%. The estimate would then be $40 billion.
The Tax Justice Network has estimated a worldwide revenue loss for all countries of $255 billion
from individual tax evasion, basically using a 7.5% return and a 30% tax rate.75 These
assumptions would be consistent with a $33 billion loss for the United States using the $1.5
trillion figure.
Alternative Policy Options to Address Corporate
Profit Shifting

Because much of the corporate tax revenue loss arises from activities that either are legal or
appear to be so, it is difficult to address these issues other than with changes in the tax law.
Outcomes would likely be better if there is international cooperation. Currently, the possibilities
for international cooperation appear to play a bigger role in options for dealing with individual
evasion than with corporate avoidance.

Tax Havens: International Tax Avoidance and Evasion

Broad Changes to International Tax Rules
The first set of provisions would introduce broad changes in international tax rules, and include
significant restrictions in deferral or allocation of income and capital.
Repeal Deferral
One approach to mitigate the rewards of profit shifting is to repeal deferral, or to institute true
worldwide taxation of foreign source income. Firms would be subject to current tax on the
income of their foreign subsidiaries, although they would continue to be able to take foreign tax
credits. According to estimates cited above, this change currently would raise from $11 billion to
$14 billion per year.
Many of the issues surrounding the repeal of deferral have focused on the real effects of repeal on
the allocation of capital. Traditionally, economic analysis has suggested that eliminating deferral
would increase economic efficiency, although recently some have argued that this gain would be
offset by the loss of production of some efficient firms from high-tax countries. Some have also
argued for retaining the current system or moving in the other direction to a territorial tax. These
economic issues are discussed in detail in another CRS report.76
Repeal of deferral would largely eliminate the value of the planning techniques discussed in this
report. There are concerns, however, that firms could avoid the effects of repeal by having their
parent incorporate in other countries that continue to allow deferral. The most direct and
beneficial to reducing firms’ tax liabilities of these planning approaches, inversion, has been
addressed by legislation in 2004.77 Mergers would be another method to counter the
implementation of deferral, although mergers involve real changes in organization that would not
likely be undertaken to gain a small tax benefit. Another possibility is that more direct portfolio
investment (i.e., buying shares of stock by individual investors) in foreign corporations will
occur. There has been a significant growth in this direct investment, although the evidence
suggests this investment has been due to portfolio diversification and not tax avoidance.78
S. 3018, a broad tax reform bill introduced by Senators Wyden and Gregg, would eliminate
deferral.
Targeted or Partial Elimination of Deferral
More narrow proposals to address deferral and tax avoidance would tax income in tax havens
currently, or tax some additional income of foreign subsidiaries. They include
• eliminating deferral for specified tax havens,

76 CRS Report RL34115, Reform of U.S. International Taxation: Alternatives, by Jane G. Gravelle.
77 Firms with 80% continuity of ownership would be treated as U.S. firms and firms with at least 60% continuity of
ownership would be subject to tax on the transfer of assets for the next 10 years.

Tax Havens: International Tax Avoidance and Evasion

• eliminating deferral in countries with tax rates that are below the U.S. rate by a
specified proportion,
• eliminating deferral for income on the production of goods that are in turn
imported into the United States,
• eliminate deferral for income on the production of goods that are exported, and
• requiring a minimum payout share.
Restricting current taxation to tax havens would likely address some of the problems associated
with transfer pricing and leveraging, without ending deferral entirely. Defining a tax haven under
those circumstances would be crucial. A bill introduced in the 110th Congress, S. 396, which
defined as a U.S. firm any U.S. subsidiary in a tax haven not engaged in an active business, had a
list of countries that was the same as the original OECD tax haven list, except for the U.S. Virgin
Islands. Some countries that are often considered tax havens, would not be subject to such
provisions, leaving some scope for corporate tax avoidance. In addition, firms could shift some
operations to other lower tax countries and increase the amount of foreign tax credits available,
which would be a loss to U.S. revenue. Some concerns have also been expressed that listing
specific tax haven countries would make cooperative approaches, such as tax information sharing
treaties, more difficult.
An alternative, which would not require identifying particular countries, would be to restrict
deferral based on a tax rate that is lower than the U.S. rate by a specified amount. For example,
the French, who generally have a territorial tax, tax income earned in jurisdictions with tax rates
one-third lower than the French rate. For the United States, whose tax rate is similar to the French
rate, this ratio would indicate a tax rate lower than 24%.
Another proposal directed to “runaway” plans would eliminate deferral for investments abroad
that produce exports into the United States. S. 1284, also in the 110th Congress, would impose
current taxation on such activities by expanding Subpart F income to include income attributable
to imports into the United States of goods produced by foreign subsidiaries of U.S. firms. The
main problem with this proposal is administering it, which would include tracing selling to a third
party for resale.
A somewhat different and more restrictive proposal was made by Senator Kerry during the 2004
presidential campaign. He proposed to eliminate deferral except in the case where income is
produced and sold in the controlled foreign corporation’s (CFC’s) jurisdiction. This approach
would, like deferral in general, be likely to significantly restrict opportunities for artificial profit
shifting, since most of the income in tax haven or low-tax jurisdictions do not arise from real
activity; indeed, these jurisdictions are too small in many cases to provide a market. As with the
previous proposal, however, the administration of such a plan would be difficult.
A final option that would not go as far as eliminating deferral altogether would be to require some
minimum share to be paid out.
Allocation of Deductions and Credits with Respect to Deferred
Income/Restrictions on Cross Crediting

A proposal that does not end deferral but makes the shifting of profits from high-tax countries less
attractive is a provision to allocate deductions and credits, so as to deny those benefits until
Congressional Research Service

income is repatriated. This approach was included in a tax reform bill introduced by Chairman
Rangel of the Ways and Means Committee in 2007 (H.R. 3970) and is included in the current
proposals by President Obama. Under this proposal, a portion of certain overall deductions, such
as interest or overhead, that reflects the share of foreign deferred income, would be disallowed.
The foreign tax credit allocation rule would allow credits for the share of foreign taxes paid that is
equal to the share of foreign source income repatriated. Disallowed deductions and credits would
be carried forward. (President Obama’s proposal does not allocate research and experimental
expenses.)
The allocation-of-deductions provision would decrease the tax benefits of sheltering income in
low-tax jurisdictions and encourage repatriation of income relative to current law and presumably
reduce profit shifting, as well as decreasing benefits of real investment abroad. The foreign tax
credit allocation rule could have a variety of effects. It would make foreign investment abroad
less attractive because it would increase the tax on income when eventually repatriated, it would
discourage investment in low-tax jurisdictions that could no longer be sheltered by foreign tax
credits, and it would discourage repatriation of earnings on existing activities because of the
potential tax to be collected.
The allocation of credits accomplishes some of the restrictions on cross crediting that could also
be achieved by increasing the number of baskets. As discussed below, one possible separate
basket would be for active royalties. Another possibility would be to impose a per country limit
with a separate basket for each country (and baskets within each for passive, active, etc., income).
S. 3018, a broad tax reform bill introduced by Senators Wyden and Gregg, would provide for a
per country limit.
Formula Apportionment
Another approach to addressing income shifting is through formula apportionment, which would
be a major change in the international tax system. With formula apportionment, income would be
allocated to different jurisdictions based on their shares of some combination of sales, assets, and
employment. This approach is used by many states in the United States and by the Canadian
provinces to allocate income. (In the past, a three factor apportionment was used, but some states
have moved to a sales based system.) Studies have estimated a significant increase in taxes from
adopting formula apportionment. Slemrod and Shackleford estimate a 38% revenue increase from
an equally weighted three-factor system.79 A sales-based formula has been proposed by Avi-
Yonah and Clausing that they estimate would raise about 35% of additional corporate revenue, or
$50 billion annually over the 2001-2004 period.80
The ability of a formula apportionment system to address some of the problems of shifting
income becomes problematic with intangible assets.81 If all capital were tangible capital, such as

U.S. and Foreign Source Income: A Firm Level Analysis,” International Tax and Public Finance, vol. 5, no. 1, 1998,

Tax Havens: International Tax Avoidance and Evasion

buildings and equipment, a formula apportionment system based on capital would at least lead to
the same rate of return for tax purposes across high-tax and low-tax jurisdictions. Real distortions
in the allocation of capital would remain, since capital would still flow to low-tax jurisdictions,
but paper profits could not be shifted. An allocation system based on assets becomes more
difficult when intangible assets are involved. It is probably as difficult to estimate the stock of
intangible investment (given lack of information on the future pattern of profitability) as it is to
allocate it under arms-length pricing. In the case of an allocation based on sales, profits that might
appropriately be associated with domestic income as they arise from domestic investment in
R&D would be allocated abroad. Moreover, new avenues of tax planning, such as selling to an
intermediary in a low-tax country for resale, would complicate the administration of such a plan.
Whether the benefits are greater than the costs is in some dispute.
One problem is that if the Untied States adopted the system there could be double taxation of
some income and no taxation of other income unless there were a multinational plan. The
European Union has been considering a formula apportionment, based on property, gross receipts,
number of employees and cost of employment. This proposal and the consequences for different
countries are discussed by Devereux and Loretz.82 If the European Union adopted such a plan it
would be easier for the United States to adopt a similar apportionment formula without as much
risk of double or no taxation with respect to its major trading partners.
Eliminate Check the Box, Hybrid Entities, and Hybrid Instruments; Foreign
Tax Credit Splitting From Income

A number of proposals have been made to eliminate check the box, and in general to adopt rules
that would require that legal entities be characterized in a consistent manner by the United States
and the country where the entity is established. This proposal has been made by McIntyre.83 In
general rules to require that legal entities be characterized in a consistent manner by the United
States and by the country where established and that tax benefits that arise from inconsistent
treatment of instruments be denied would address this particular class of provisions that
undermine Subpart F and the matching of credits and deductions with income. President Obama’s
proposal includes a provision that disallows a subsidiary to treat a subsidiary chartered in another
country as a disregarded entity. It also includes a provision to prevent foreign tax credits without
the associated income, which can currently be accomplished with reverse hybrids. This provision
is included in H.R. 4213, the American Jobs and Closing Loopholes Act, passed by the House.
Narrower Provisions Affecting Multinational Profit Shifting
A number of more narrow provisions could be considered that would be more focused on
preventing abuses and have fewer consequences for the overall structure of international
corporate taxation.

Tax Havens: International Tax Avoidance and Evasion

Tighten Earnings Stripping Rules
In the American Jobs Creation Act a further restriction on earnings stripping rules was considered
as an alternative to the anti-inversion measure. These provisions were not enacted, but were to be
studied in a Treasury report. The 2004 House proposal would have raised revenue by dropping
the debt to asset share test and lowering the interest share standard to 25% for ordinary debt, 50%
for guaranteed debt, and 30% overall. In general, further restrictions on earnings stripping could
be considered to address shifting through debt for U.S. subsidiaries of foreign parents.
President Obama’s plan includes dropping the asset test and lowering the interest share standard
to 25% for inverted firms, with respect to related party non-guaranteed debt.
Foreign Tax Credits: Source Royalties as Domestic Income for Purposes of the
Foreign Tax Credit Limit, Or Create Separate Basket; Eliminate Title Passage
Rule; Restrict Credits for Taxes Producing an Economic Benefit; Address
Specific Techniques for Enhancing Foreign Tax Credits

As noted above, one of the issues surrounding the cross-crediting of the foreign tax credit is the
use of excess credits to shield royalties from U.S. tax on income that could be considered U.S.
source income. Two options might be considered to address that issue: sourcing these royalties as
domestic income for purposes of the credit or putting them into a separate foreign tax credit
basket.84 The same issue applies to the provision that allows half of the income from exports to be
allocated to the country in which the title passes. President Obama’s proposal includes a provision
to restrict the crediting of taxes that are in exchange for an economic benefit (such as payments
that are the equivalent of royalties).
H.R. 4213, the American Jobs and Closing Loopholes Act, passed by the House, would address a
number of specialized techniques for increasing foreign tax credits.
Transfer pricing
Michael McIntyre has suggested some other proposals to deal with transfer pricing, which include
making transfer pricing penalties nearly automatic for taxpayers who have not kept
contemporaneous records. He also suggests use of some type of formula apportionment plan as a
default for transfer pricing for non-complying taxpayers so the IRS does not have to conduct a
detailed transaction by transaction assessment for the court.
President Obama’s proposals would address some of the transfer pricing issues associated with
the transfer of intangibles by clarifying that intangibles include workforce in place, goodwill, and
going concern value and that they are valued at their highest and best use. The plan would allow
the IRS Commissioner to aggregate intangibles if that leads to a more appropriate value.

Tax Havens: International Tax Avoidance and Evasion

These proposals would likely have small effects. Any significant solution to the transfer pricing
problem, especially for intangibles, is difficult to entertain short of an elimination of deferral.
The President’s FY2011 budget proposal included a plan to treat excess returns on intangibles in a
low-tax country as Subpart F income (and therefore not subject to deferral) and to place it in a
separate foreign tax-credit basket. If such an approach could be successfully implemented it
might have important consequences for transfer pricing using intangibles.
Codify Economic Substance Doctrine (Enacted Provision)
The economic substance doctrine was recently adopted in the health reform legislation, P.L. 111-
148. This provision is relevant to international tax evasion and avoidance. Firms that enter into
tax savings arrangements that are found not to have economic substance can have their tax
benefits disallowed by the courts under what has become known as the economic substance
doctrine. The doctrine is sometimes interpreted differently by different courts and recent
legislative proposals have sought to make the doctrine more uniform through statute. Generally
these proposals would require a transaction to meet both an objective test (profit was made) and a
subjective test (profit was intended). Penalties are also imposed. Supporters argue that the stricter
test will not only reduce tax avoidance but also make treatment more consistent across the courts.
Some tax attorneys are concerned that more specific rules might provide a roadmap to structuring
arrangements that will pass the test. The provision adopted in P.L. 111-148 included a two-part
statutory standard.
Prevent Dividend Repatriation Through Reorganizations (Boot Within Gain)
President Obama’s plan would revise the rule on reorganizations when property as well as stock
is received to treat distributions as dividends in the case of cross-border transactions, and this
provision is included in H.R. 4213, the American Jobs and Closing Loopholes Act, passed by the
House.
Options to Address Individual Evasion
Most of the options for addressing individual evasion involve more information reporting and
additional enforcement. There are options that would involve fundamental changes in the law,
such as shifting from a residence to a source basis for passive income. That is, the United States
would tax this passive income earned in its borders, just as is the case for corporate and other
active income. This change involves, however, many other economic and efficiency effects that
are probably not desirable. The remainder of the proposals discussed here do not involve any
fundamental changes in the tax itself, but rather focus on administration and enforcement.
The options discussed below are drawn from many sources, including academics and
practitioners, organizations, and the Internal Revenue Service, and contained in legislative
proposals; citations to these sources are provided at this point and legislative proposals are
summarized in the next section.85

Congressional Research Service
28

Tax Havens: International Tax Avoidance and Evasion

Some of the options discussed in this section are included in the HIRE Act, P.L. 111-147, and that
inclusion will be noted.
Information Reporting
Expanded information reporting can involve multilateral efforts, changes in the current bilateral
treaties, or unilateral changes.
Multilateral Information Sharing or Withholding; International Cooperation
The option that appears likely to recover most of the revenues would be to join in the European
Union Directive, which would require information reporting on all income paid to foreign entities
by U.S. banks and other institutions. If the beneficial owner cannot be identified, withholding
could be imposed (a refund would be allowed if evidence of reporting to the home country could
be shown). This approach has been proposed by the Tax Justice Network, which also suggests
expanding the treaty to other tax havens. If the European Union is receptive, it would benefit
other countries by reporting income paid to foreign nationals and benefit the United States by
achieving third party information reporting on foreign investments of U.S. citizens.
Avi-Yonah and Avi-Yonah and Guttentag have suggested that current Treasury policy is to focus
on bilateral agreements to achieve information exchange, but that the United States should also
focus on cooperation with the OECD and G-20 and other appropriate organizations to improve
information and persuade tax havens to enter into exchanges based on the OECD model. Shay
suggests this approach as well and particularly references electronic information exchange.
The Tax Justice Network has proposed that the United Nations develop a global tax cooperation
standard, set up a panel to determine compliant states, and deny recognition to non-compliant
jurisdictions. They have also suggested that the IMF and World Bank country assessments
address tax compliance.
Expanding Bilateral Information Exchange
A number of commentators have suggested an increase in the scope of bilateral information
treaties to provide for regular and automatic exchanges of information. This would require the
U.S. banks to increase their collection of information.
Avi-Yonah and Avid-Yonah and Guttentag suggest adopting the model OECD bilateral Tax
Information Exchange Agreement (TIEA ). This information exchange would relate to civil as
well as criminal issues, it would not require suspicion of a crime other than tax evasion, and
would override tax haven bank secrecy laws. Non-tax havens could be induced to make such

agreements to obtain information, and thus, such a change would require collection of
information on interest payments by banks and financial institutions. Treasury has proposed only
16 countries, but Avi-Yonah and Guttenberg suggest no reason to restrict the provision in this
way. Treasury could use existing authority not to exchange information that might be misused by
non-democratic foreign governments.
Martin Sullivan suggests that automatic information exchange might be the only way to stop
evasion, which would require renegotiating existing agreements and a major policy change. He
notes that that the proposed Stop Tax Haven Abuse Act (S. 506, H.R. 1265) requires automatic
information exchange for a country to stay off the tax haven list.
Unilateral Approaches: Withholding/Refund Approach; Increased Information
Reporting Requirements

This step is one that the United States could undertake without multilateral or bilateral
cooperation, namely imposing withholding taxes on interest income and other exempt income
received from U.S. sources by foreign intermediaries and providing a refund upon proof that the
beneficial recipient was eligible. Avi-Yonah suggests this change with the hope that it would be
adopted multilaterally.
A variation of this approach would be to require disclosure of the names of customers including
beneficial owners, with withholding imposed if disclosure was not forthcoming. Such a proposal
has been made by Michael McIntyre, and has been included, for accounts identified as U.S.
beneficiaries in the HIRE Act, P.L. 111-147. The Stop Tax haven Abuse Act and President
Obama’s budget proposals addressed these issues as well. S. 3018, the Wyden-Gregg tax reform
act, requires withholding on all accounts unless information on the beneficial owner is supplied,
without an initial determination by the institute that the account has a U.S. owner.
President Obama’s proposals also include provisions to require information reporting by U.S.
financial intermediaries and qualified intermediaries on transfers of funds and by U.S. persons
and qualified intermediaries on the formation or acquisition of a foreign entity.
The proposed Stop Tax Haven Abuse Act would also require reporting by U.S. shareholders and
persons forming, sending, or receiving assets from Passive Foreign Investment Corporations
(PFICs), and this provision was included in the HIRE Act, P.L. 111-147.
Other Measures That Might Improve Compliance
Incentives/Sanctions for Tax Havens
Avi-Yonah and Avi-Yonah and Guttenberg suggest a carrot and stick approach to tax havens.
They argue that little of the benefit of tax havens flows to their sometimes needy residents, but
rather to the professionals providing banking and legal services, who often live elsewhere. They
suggest transitional aid to move away from these offshore activities. For non-cooperating tax
havens, they suggest the Treasury use its existing authority to deny benefits of the interest
exemption. They suggest that tax havens cannot continue to exist unless the wealthy countries
permit it, because funds are not productive in tax havens.
Congressional Research Service
30

Tax Havens: International Tax Avoidance and Evasion

The proposed Stop Tax Haven Abuse Act would extend to tax enforcement the sanctions of the
Patriot Act used to impose penalties for money laundering and terrorist financing. Sanctions vary
in severity and range from increased reporting on transactions to prohibitions. Sullivan points out
that the U.S. government has used the Patriot Act sparingly, however, and questions whether this
change would be a credible threat.
Blessing suggests that sanctions should be multilateral rather than unilateral.
Revise and Strengthen the Qualified Intermediary (QI)Program
Several proposals relating to the QI program, which were discussed by witnesses at a Ways and
Means Committee hearing on March 31, 2009, were reported by Sullivan. Some of these
provisions are also included in the proposed Stop Tax Haven Abuse Act. If enough effective
revisions could be made in the QI program, a great deal of potential information about U.S.
taxpayers’ income would be obtained. These proposals include the following. QIs would be
required to inquire about and independently verify the ownership of foreign corporations and
similar entities, information that they already must acquire to deal with money laundering. QIs
would also be required to report any non-U.S. income of U.S. taxpayers. QIs would be required to
submit information electronically, and IRS would be given resources to handle and use this
information. The current exemption from withholding rules for bearer bonds (where no
registration occurs) would be eliminated. Another possible change is to require QIs to share
information about foreign customers to U.S. treaty partners (although one witness warned that
this might be too severe a requirement). Finally, external audits of QIs would be strengthened by
requiring QIs to promptly notify the IRS of any material failure in oversight, improve the
evaluation of risk of circumvention of U.S. taxes by U.S. persons, and require audit oversight by
a U.S. auditor.
Blum emphasizes the problem of accepting a shell corporation as the beneficial owner, and says
this loophole in the law should be closed. He also suggests that penalties for failure to enforce
should include withholding of capital gains as well as interest and dividends.
McIntyre stresses that audits of the QIs should be done by firms that do not at the same time sell
tax shelters. Avi-Yonah and Avi-Yonah and Guttentag also suggest that IRS should require U.S.
payors to issue form 1099s when they know or have reason to suspect the beneficial owner is a
U.S. citizen (rather than the W8-BEN which provides evidence of foreign status).
President Obama’s proposals would revise the treatment of non-qualified intermediaries. As noted
above, the proposal includes a withholding/refund mechanism for non-qualified intermediaries. It
would require that QIs can qualify only if all of their affiliates are QIs and, as noted above,
increase information reporting by QIs.
The HIRE Act, P.L. 111-147, discussed below, contains some modifications in this area.
Placing the Burden of Proof on the Taxpayer
An important part of the Stop Tax Haven Abuse proposal is to place the burden of proof in court
on the taxpayer; this approach was also suggested by Blum. As noted above, there is also a shift
in the burden of proof for accounts with non-qualified intermediaries for filing an FBAR (Foreign
Bank and Financial Account Report).
Congressional Research Service
31

Tax Havens: International Tax Avoidance and Evasion

President Obama’s proposal would create a presumption that the funds in foreign accounts are
large enough to require an FBAR, which is required when amounts exceed $10,000. It would treat
failure to file for amounts in excess of $200,000 as willful, which permits criminal penalties and
larger civil penalties.
The HIRE Act (P.L. 111-147) would assume that, when adequate information is not provided,
foreign accounts exceed the $50,000 minimum that requires reporting (under other provisions) on
the tax return for purposes of assessing penalties.
Treat Shell Corporations as U.S. Firms
The Stop Tax Haven Abuse Act includes a provision to treat any firm that is publicly traded or has
assets over $50 million as a U.S. corporation. This provision would include hedge funds but
would not affect subsidiaries of multinational firms because decisions are made by the parent
firm. Sullivan argues that such a provision would have a devastating effect on the U.S. hedge
fund industry, where offshore firms generally attract tax exempt U.S. investors and foreigners
who wish to avoid filing tax returns, as well as U.S. tax evaders, and that legislative relief for
U.S. tax exempt investors (pension funds, university endowments) would be likely.
Impose Restrictions on Foreign Trusts
The proposed Stop Tax Haven Abuse Acts would impose further restrictions on foreign trusts, by
providing that any powers held by trust protectors would be attributed to the trust grantor,
providing that any U.S. person who benefits from the trust will be treated as a formal beneficiary
even if not named, providing that a future or contingent beneficiary be treated as a current one,
and treating loans of assets and property as distributions. The Senate Finance Committee draft
would expand the definition of contributions to include items such as art and jewelry. The HIRE
Act (P.L. 111-147) includes these provisions.
Treat Dividend Equivalents as Dividends
As noted earlier, the withholding tax on dividends has been avoided with the use of derivatives
and other arrangements to re-characterize them as interest. The proposed Stop Tax Haven Abuse
Act would treat dividend equivalents as dividends. Proposals for change in this area were also
made by Avi-Yonah. President Obama’s plan treats equity swaps as dividends. The HIRE Act
(P.L. 111-147) includes this provision.
Extend the Statute of Limitations
Extensions in the statute of limitations are said by some to be needed due to the complexity of the
international cases and difficulty of obtaining information. Extension has been proposed by
numerous commentators, is supported by the IRS officials and is included in the proposed Stop
Tax Haven Abuse Act , proposals discussed by the Senate Finance Committee, and proposals
made by President Obama. These legislative proposals would extend the statute of limitations
from three years to six years, but Blum also suggests the possibility of 10 years. The HIRE Act
(P.L. 111-147) extends the statute of limitations to six years.
Congressional Research Service
32

Tax Havens: International Tax Avoidance and Evasion

Greater Resources for the Internal Revenue Service to Focus on Offshore
Numerous suggestions have been made to expand IRS resources for combating overseas tax
abuses. President Obama’s proposal, for example, has proposed to fund 800 new positions to
combat international abuses.
Blum says that agents should not be pressured to give up difficult cases because of short-term
performance goals based on closing cases and collecting revenues.
Make Civil Cases Public as a Deterrent
Blum suggests all settlements involving offshore schemes in excess of $1 million should be
excluded from the restrictions of Section 6103 that require settled civil cases to be confidential.
He argues that no one knows about these cases and thus taxpayers think the possibility of being
caught is small.
Revise Rules for FBAR (Foreign Bank Account Report)
Blum argues that language in the FBAR should be clarified to make it easier for the Justice
Department to pursue cases; the proposed Stop Tax Haven Abuse Act would change the
disclosure rules to make this information easier to use. The FBAR report on foreign bank
accounts is filed separately from the tax return; individuals must check a box to indicate whether
or not they have these accounts. It is possible that a reporting requirement on the tax return would
increase the visibility and force of this requirement. The Senate Finance Committee would
require this report to be filed with the tax return and require due diligence on the part of tax
preparers to determine if it should be filed. (Note also, as discussed below, that some of the
strengthened penalties relate to FBAR.) President Obama’s FY2010 plan would require the
information from the FBAR to also be reported on the tax return and any transfer of funds that
sums to more than $10,000 would also be reported. His FY2011 plan increases the minimum to
$50,000, and this provision is included in the HIRE Act (P.L. 111-147).
John Doe Summons
A provision in the proposed Stop Tax Haven Abuse Act would make it easier to issue John Doe
summons where the IRS does not know the names of taxpayers and now must ask courts for
permission to serve the summons. This section provides that in any case involving offshore secret
accounts, the court is to presume tax compliance is at issue, to relieve the IRS of the obligation
when the only records sought are U.S. bank records, and to issue John Doe summons for large
investigative projects without addressing each set of summons separately.
Strengthening of Penalties
Increased penalties are included in the proposed Stop Tax Haven Abuse Act, the Finance
Committee Draft and President Obama’s proposals. Among the penalty provisions in various
proposals are increased penalties for failure to file FBARs; basing the FBAR penalty on the
highest amount in period rather than on a particular day; and increased penalties on abusive tax
shelters, failure to file information on foreign trusts, and certain offshore transactions. President
Obama’s proposals would double accuracy-related penalties for foreign transactions and increase
Congressional Research Service
33

Tax Havens: International Tax Avoidance and Evasion

penalties for trusts and permit them to be imposed if the amount in the trust cannot be established;
this provision was included in The HIRE Act (P.L. 111-147).
The proposed Stop Tax Haven Abuse Act also includes a provision that legal opinions that take
the position that a transaction is more likely than not to prevail for tax purposes will no longer
shield taxpayers from penalties.
S. 386, the Fraud Recovery and Investment Act. would introduce criminal penalties. Some tax
attorneys have questioned whether these proposals are too harsh or might undermine amnesty or
voluntary compliance.86
Address Tax Shelters; Codify Economic Substance Doctrine
The proposed Stop Tax Haven Abuse Act would make a number of additional changes addressing
tax shelters, including prohibiting the patenting of tax shelters, developing an examination
procedure so that bank regulators could detect questionable tax activities, disallowing fees
contingent on tax savings, removing communication barriers between enforcement agencies,
codifying regulations, making it clear that prohibition of disclosure by tax preparers does not
prevent congressional subpoenas, and providing standards for tax shelter opinion letters.
It would also codify the economic substance doctrine. This proposal is discussed among options
for reducing corporate tax avoidance, but would also be applicable to individual evasion issues.
The health reform legislation (P.L. 111-148) codified the economic substance doctrine.
Regulate the Rules Used by States to Permit Incorporation
Blum suggests that all U.S. Limited Liability Companies (LLCs) have a taxpayer ID number, a
requirement not imposed in Delaware and other states that keep no records of ownership. S. 569
would tighten regulations to require record-keeping and identification of beneficial owners of
corporations and LLCs and commission a study of partnerships and trusts.
Make Suspicious Activity Reports Available to Civil Side of IRS
The proposal that information on suspicious activity reports filed by financial institutions under
anti-money laundering acts be made available to the civil side of IRS was made by Blum, who
indicated that agency policy at the top levels had prohibited this information sharing. It is
included in a provision in the Stop Tax Haven Abuse Act.

86 See Jeremiah Coder, “Proposed offshore Crime Legislation Worries Defense Bar,” Tax Notes Today, March 23,
2009. The attorneys are concerned that money laundering charges would not have to be approved through the
Department of Justice’s tax division, that penalties of up to 20 years gives prosecutors too much power, that the
provisions may trap taxpayers who want to participate in IRS voluntary disclosure, and that they would also discourage
the “quiet disclosure” where taxpayers simply report past information.
Congressional Research Service

Tax Havens: International Tax Avoidance and Evasion

Summary of Enacted Legislation
Two bills contain provisions relating to international compliance, the HIRE Act and the health
reform legislation.
The Hiring Incentives to Restore Employment (HIRE) Act
(P.L. 111-147)

The foreign provisions in this act are projected to have a relatively small effect, $8.7 billion over
10 years, when compared with estimated costs of international evasion of around $40 billion a
year.
Reporting on Foreign Accounts
This provision would institute withholding on payments, at a 30% rate, to foreign financial
institutions and other institutions unless certain requirements are met. Although the provision
allows considerable regulatory scope, the requirements include providing specific details on U.S.
beneficial owners. The institution determines U.S. beneficial owners, with oversight by the
Treasury.
Deduction of Interest for Bearer (Non-Registered) Bonds
Non-registered bonds (with some exceptions, including those issued by natural persons, not for
public sale, or of maturities of less than a year) are subject to restrictions, including an excise tax
and denial of interest deductions; there is an exception for foreign targeted bonds. Foreign-
targeted bonds are designed to be sold to non-U.S. persons, payable outside of the United States,
and containing a statement that any bond held by a U.S. person will be subject to U.S. tax laws.
This provision would repeal the foreign targeted bond exception for purposes of interest
deductibility. Non-registered state and local bond interest for these bonds are also not eligible for
tax exclusion.
Additional Information Reported on Tax Returns
Individuals who are required to file an FBAR (Foreign Bank and Financial Account Report)
would also be required to report this information on the tax return if the amount in the account is
$50,000 or more. For purposes of this report on the tax return, interests in foreign trusts would
also be included. A presumption will be made that the amount of the account is at least $50,000
when no detailed information is provided.
Penalties
The 20% accuracy-related penalty that already applies would be increased to 40% for transactions
involving foreign accounts where the taxpayer failed to disclose reportable information. A
reasonable cause exception would not be available. In the case of failure to report or under-
reporting foreign trusts, the initial penalty is 35% of the trust amount (5% in certain cases). If the
failure to report continues for 90 days, an additional penalty of $10,000 is imposed for each 30-

35

Tax Havens: International Tax Avoidance and Evasion

day period, but the total cannot exceed the amount of the trust. This provision would change the
initial penalty from 35% (5%) of the trust amount a minimum of $10,000. The $10,000 for each
30-day period would be continued indefinitely, with a refund of any excess when the taxpayer
does report. This proposal addresses the problem of the IRS not being able to assess a penalty
because it cannot determine the amount in the account.
Statute of Limitations
The statute of limitations for cross-border transactions is extended from three to six years in
instances where more than $5,000 of income is omitted.
Reporting on Foreign Passive Investment Companies
The legislation addresses reporting by passive foreign investment companies (PFICs) by
codifying proposed regulations requiring shareholders to file annual information reports. The
Secretary of the Treasury has regulatory authority over the type of information and can also
provide for regulations that address duplicate reporting from other provisions in the legislation.
Electronic Filing
Electronic filing is required of persons who file at least 250 returns (including information
returns). This legislation requires electronic filing for financial institutions regardless of whether
the institution provides 250 returns, which would generally be relevant to foreign financial
institutions.
Trusts
The legislation would further restrict foreign trusts by treating the grantor as the owner if there is
a future contingency for a U.S. beneficiary or an agreement the grantor is involved in that might
provide for a U.S. beneficiary. It also places the burden of proof on the grantor, treats a loan or
use of property without appropriate compensation as a benefit, and requires information
reporting.
Treat Equity Swaps as Dividends
This provision addresses the problem of disguising dividends that are subject to taxation as
interest that is not. This provision, which would generally treat equity swaps as dividends, would
raise $1.1 billion for FY2011-FY2020 according to the President’s proposals.
Economic Substance Doctrine: The Patient Protection and
Affordable Care Act, P.L. 111-148.

The health reform included the codification of the economic substance doctrine, requiring both a
subjective (profit intended) and objective (profit achieved) test. This provision has been enacted
as part of the revenue offsets and, although not specifically targeted to foreign transactions, would
have a potential impact.

Tax Havens: International Tax Avoidance and Evasion

The Act: P.L. 111-226
On May 20, 2010, the Ways and Means Committee Chairman Levin and Senate Finance
Committee Baucus released a plan for combining Senate and House proposals for extending
temporary tax benefits and providing for spending increases.87 Among the revenue raisers were
several foreign provisions largely relating to the foreign tax credit, which were developed jointly
with the Treasury Department. Some are also included in the President’s 2011 budget proposals.
They would raise $14.451 billion over 10 years. These provisions were adopted as part of H.R.
4213 on May 28, 2010.
Some of these issues arise from the overall limit on the foreign tax credit, which allows aggregate
foreign taxes paid abroad to be credited against U.S. tax on aggregate foreign earnings. Under
these rules, firms are either in excess credit positions (they have foreign taxes that cannot be used
because aggregate foreign taxes exceed aggregate U.S. tax on foreign source income) or in an
excess limit position (they don’t have enough foreign taxes to offset U.S. tax on foreign source
income). In the former case, any technique that increases the amount of their income that is
considered foreign source reduces overall tax because it increases the limit on foreign tax credits;
in the latter case, any technique that allows recognition of foreign taxes without the
accompanying income reduces taxes.
H.R. 4213 was not enacted, but a smaller spending bill using H.R. 1586 as a vehicle included
most of the foreign provisions in H.R. 4213. H.R. 1586 provided money to the states for
education and Medicaid funding, with costs paid for in part by these foreign revisions. It was
signed into law on August 10, 2010. The provisions are summarized below.
Preventing Splitting Foreign Tax Credits from Income
This provision would address the issue of reverse hybrids and mechanisms that allow firms to
recognize and take credits for foreign taxes paid without reporting the income that gave rise to the
foreign taxes (discussed earlier in this report), thus using those credits to offset tax on unrelated
income. The proposal would implement a matching rule so that foreign tax credits would not be
recognized until the income is taken into account. This proposal is estimated to raise $6.325
billion over 10 years.
Denial of Foreign Tax credits for Covered Asset Acquisitions
Taxpayers can acquire a firm by purchasing stock or by purchasing the underlying assets. In the
latter case, assets are valued at current market value, which generally increases depreciation
deductions. Certain U.S. tax rules allow a stock acquisition to be treated as an asset acquisition.
Foreign governments may not apply a similar rule. As a result, depreciation deductions under the
foreign rules are smaller than under the U.S. rules, and income and foreign taxes paid are higher.
The excess of foreign taxes over U.S. taxes on this transaction can be used to offset U.S. tax on
unrelated foreign income under the overall foreign tax credit limitation. Such an outcome can also
occur when taxpayers acquire entities that are partnerships for U.S. purposes and corporations for

Tax Havens: International Tax Avoidance and Evasion

foreign tax purposes. The proposal would prevent firms from obtaining credits for these excess
taxes. This proposal is estimated to raise $4.025 billion over 10 years.
Separate Foreign Tax Credit Limit for Items Resourced Under Treaties
Current tax treaties provide that some income that would normally be considered U.S. source
income can be resourced in foreign countries. For example, interest paid on U.S. securities to a
firm’s foreign subsidiary would normally be U.S. source income, but under a treaty may be
sourced in the foreign country. The foreign country may tax net interest (interest income less
interest paid), but the entire gross interest payment would be considered foreign source and
eligible for offsetting foreign tax credits. This increase in foreign source income could, absent
other provisions, lead to tax reductions from excess foreign taxes on other income. Current law
places this operation in a separate foreign tax credit basket when the foreign firm is a subsidiary
of a U.S. firm incorporated abroad. This provision extends the treatment to branch operations and
disregarded entities (that are treated the same as branches under check the box rules). The
provision would apply to taxable years beginning after the date of enactment. This proposal is
estimated to raise $253 million over 10 years.
Limitation on the Use of Section 956 (the “Hopscotch” Rule)
The hopscotch rules issue arises from the combination of two different tax provisions. The first is
the treatment of dividends from foreign subsidiaries when there are multiple tiers of these
subsidiaries. For example, a U.S. parent might have a subsidiary (tier 1), which in turn has a
subsidiary (tier 2). If a tier 2 firm wants to pay a dividend to the parent, it would first be paid to
the tier 1 subsidiary, which would in turn pay it to the parent. The foreign tax credit allowed
would be a blend of the tax rate in the tier one subsidiary and the tier 2 subsidiary. For example, if
one-half of the income of the tier 1 subsidiary was its own and the tax rate was 10% and one-half
was from the payment from the tier 2 firm with a 50% tax rate, and dividend paid by the tier 1
subsidiary to the U.S. parent would have a 30% rate. These deemed taxes paid could be used for
foreign tax credits against any U.S. tax on foreign source income. The second provision is Section
956, which was designed to prevent firms from returning income to the U. S. parent without
paying tax, but using methods such as lending to the parent or buying property from the parent. A
payment made in this fashion is construed as a dividend. Therefore, if the tier 2 subsidiary made a
transaction that fell into the Section 956 rules, it could “hopscotch” over the tier 1 subsidiary and
receive a full 50% tax rate: two-thirds larger than the 30% rate allowed under the blended credit
rule. This provision preserves the blended rate in the case of Section 956 transactions. This
proposal is estimated to raise $1.010 billion over 10 years.
Special Rule for Certain Redemptions by Foreign Subsidiaries
This issue relates to circumstances where a foreign multinational company owns a U.S. firm,
which in turn owns a foreign subsidiary, and the foreign subsidiary purchases stock in the U.S.
firm from the foreign multinational with cash. The cash payment can be considered a direct
dividend payment to the foreign multinational up to the earnings and profits of the foreign
subsidiary and thus bypasses the U.S. tax system. (If earnings and profits of the subsidiary are
exhausted the payment comes from earnings and profits of the U.S. company and are subject to
dividend withholding taxes unless exempted by treaty.) The earnings and profits of the foreign
subsidiary are reduced by the amount of the payment so that they are not available for future
taxation. If the foreign subsidiary had paid a dividend directly to the U.S. parent, it would have
Congressional Research Service
38

Tax Havens: International Tax Avoidance and Evasion

been subject to tax at the firm level and to a withholding tax on the dividend (unless exempted by
treaty). This provisions would not allow earnings and profits of the foreign subsidiary to be taken
into account if more than 50% of the dividend would bypass the U.S. tax system. This proposal is
estimated to raise $255 million over 10 years.
Modification of Affiliation Rules for Allocating Interest Expense
Foreign tax credits are limited to the U.S. tax that would be due on foreign source income if taxed
in the United States. In determining foreign source income, a share of the interest paid by the U.S.
parent and related U.S. affiliates is assigned to foreign income based on the share of total assets
that are foreign. The more interest that is assigned to foreign sources, the smaller the foreign
source income and the lower the foreign tax credit limit. Although the affiliate rules generally
exclude foreign corporations, a special provision applies to foreign affiliates that are 80% owned
and where 50% of earnings are effectively connected to U.S. business to prevent firms from
hiding their interest in these types of affiliates. If the effectively connected earnings are greater
than 80%, all interest and assets are taken into account. If the effectively connected earnings are
between 50% and 80%, only the effectively connected assets and earnings are included. This
provision provides that all assets and interest are included as long as effectively connected
earnings are 50% or more. This proposal is estimated to raise $405 million over 10 years.
Repeal of 80/20 Rules
Under current law, dividends and interest paid by a domestic corporation are generally U.S.
source income and subject to gross basis withholding if paid to a foreign person. (As discussed
earlier in this report, portfolio interest and bank deposit interest paid to foreigners is exempt.)
Interest and dividends paid by a firm with a least 80% of its gross income foreign source and due
to an active foreign business are not subject to withholding. This interest can also increase foreign
source income and the foreign tax credit limit. The determination of eligibility is made during the
previous three-year period. The bill would repeal the 80/20 company rules (and also the 80/20
rules for resident alien individuals). The proposal would grandfather existing 80/20 companies if
they also meet a new test (that combines the company with its existing subsidiaries) and if it does
not add a new substantial line of business. It also excludes payment of interest on existing
obligations. This provision is estimated to raise $153 million over 10 years.
Technical Correction to the HIRE Act
The bill would make a technical correction to the foreign compliance provisions of the Hiring
Incentives to Restore Employment Act (P.L. 111-147) to clarify the statute of limitations.
Summary of Legislative Proposals
This section summarizes current legislative proposals that are designed to address or have
consequences for international tax evasion and avoidance.
Congressional Research Service
39

Tax Havens: International Tax Avoidance and Evasion

American Jobs and Closing Loopholes Act (H.R. 4213)
As noted above, most foreign provisions in H.R. 4213 were included in the act, P.L. 111-226.
Below are two provisions, one specifically a foreign provision and one related to foreign tax
issues, that were not included.
Source Rules on Guarantees
Dividends and interest are generally sourced depending on the residence of the payor, whereas
payments for services are sourced to the country where the service is performed. The treatment of
guarantee fees is unclear, depending on whether compared to interest or services. Sourcing these
payments like services allows U.S. subsidiaries of foreign firms to make deductible payments that
reduce U.S. income without paying the withholding tax (as they would with interest). This
provision treats these fees the same as interest: sourced to the residence of the payor. Payments by
foreign persons are also U.S. source if allocable to income effectively connected with U.S.
business. Treasury is to identify other transactions that are in the nature of guarantees. This
proposal is estimated to raise $2.025 billion over 10 years.
Boot-Within-Gain
The boot-within-gain revisions are generally applicable to domestic as well as foreign activities,
but have implications for international transactions. When a person or firm sells stock and uses
the proceeds to purchase other stocks, capital gain is recognized to the extent that the sales price
of the stock exceeds the basis of that stock (typically what was originally paid for it). In general, a
gain is not recognized in exchanges of stock in corporate reorganizations. If the exchange
includes cash or property (“boot”), gain is recognized to the extent of the boot. If the boot is more
than the gain, all of the boot will not be taxed. However, if the boot is considered equivalent to a
dividend, it will be taxed in full. One of the rules that allows the payment not to be considered as
a dividend is a termination of interest (liquidation). Check-the-box rules permit a transaction to be
considered a liquidation for U.S. purposes (i.e., a disregarded entity), but not for foreign
purposes. Thus one foreign subsidiary of a U.S. firm can pay cash to the U.S. parent for stock in
another foreign subsidiary of the U.S. firm without the transactions being viewed as a dividend
repatriation, thereby potentially reducing U.S. tax. In addition, two U.S. subsidiaries of a foreign
parent can engage in a similar transaction without generated a U.S. withholding tax on the
dividend. If the foreign parent does not have a treaty eliminating the tax, this treatment reduces
U.S. taxes. This revision would treat payments in these cases as a dividend.
President Obama’s International Tax Proposals88
President Obama’s international proposals include several proposals that relate to multinational
corporations: allocation of deductions and credits, a restriction on use of foreign tax credits when
associated income is not recognized, and a restriction on check-the-box. They also include
proposals addressing individual tax evasion. Overall these provisions are projected to raise $210
billion for FY2010-FY2019 as presented in the 2010 budget and $122 billion for FY2011-

Tax Havens: International Tax Avoidance and Evasion

FY2020 as presented in the FY2011 budget. The provisions are discussed in the order in which
they are presented unless otherwise noted, since revenue effects depend on that order. Note also
that the budget proposes additional resources for the IRS for international enforcement.
Some of the President’s proposals have been adopted. Two provisions relating to foreign tax
credits were enacted in P.L. 111-226, and are noted. The HIRE Act (P.L. 111-147) included a
provision treating equity swaps and other dividend equivalent payments as dividends; the other
foreign compliance provisions were, in most cases, also in the President’s FY2010 or FY2011
proposals. These provisions are not listed. The health reform legislation also included the
economic substance doctrine which, although not specifically part of the international provisions
in the budget proposals, is relevant to foreign enforcement.
Provisions Affecting Multinational Corporations and Other Tax Law Changes
Hybrid Entities and Check-the Box
The most significant provision in the FY2010 budget, based on revenue gain, is a revision
directed at hybrid entities and check-the-box. This provision requires that a corporation cannot
disregard a subsidiary corporation unless it is incorporated in the same jurisdiction. This rule does
not apply to the parent and its first level subsidiary. Thus, a U.S. parent with a subsidiary in a low
tax country could treat that subsidiary as a branch (disregard it as a separate entity). The
subsidiary in the low-tax country, however, could not treat its own high-tax country subsidiary as
a disregarded entity. This provision was included in the FY2010 proposals, where it was projected
to raise $86.5 billion for FY2010-FY2019.89 It was not included in the FY2011 budget.
Allocation of Deductions and Credits
Two of these proposals would allocate deductions and credits, so as to deny those benefits until
income is repatriated. This approach was included in a tax reform bill introduced by Chairman
Rangel of the Ways and Means Committee in 2007 (H.R. 3970). A portion of overall deductions,
such as interest, that reflects the share of foreign deferred income, would be disallowed until the
income is repatriated. The foreign tax credit allocation rule would allow credits for the share of
foreign taxes paid that is equal to the share of foreign source income repatriated, a provision the
discussion of the proposals refers to as pooling. Disallowed deductions and credits would be
carried forward. The proposal specifically excludes deductions for research and experimentation
from the allocation rule. The FY2011 budget proposal was narrower, and it was limited to interest
deductions; it also includes a different set of allocation rules.
The revenue gain for FY2019-FY2020 was $25.6 billion for the limit on interest deductions and
$32.0 billion for the foreign tax credit pooling. The FY2010-FY2019 budget proposal was $60.1
billion for the deduction allocation and $24.5 billion for the foreign tax credit pooling in the
FY2010 budget.

Explanations of the Administration’s Fiscal Year 2010 Revenue Proposals, http://www.treas.gov/offices/tax-policy/

Tax Havens: International Tax Avoidance and Evasion

Limiting the Foreign Tax Credit; Reverse Hybrids (Enacted in P.L. 111-226)
Another provision aimed at multinational corporations would disallow foreign tax credits when
the associated income is not received, as can occur with reverse hybrids. A matching rule would
apply. This provision is estimated to raise $27.4 billion for FY2011-FY2020. (Note that a similar
proposal was included in H.R. 4213, but was scored at only $6 billion).
Taxing Excess Returns on Intangibles
This provision, which appears only in the 2011 budget proposal, would treat excess returns in a
low-tax country on intangibles transferred to it from the United States as Subpart F income
(subject to current taxation) and in a separate foreign tax credit basket (so that other foreign taxes
could not offset U.S. taxes due on the excess returns). This provision is scored at $15.5 billion for
FY2011-FY2020.
Transfer Pricing of Intangibles
The proposal would clarify several rules that are relevant to the transfer of intangibles. First, it
would clarify that intangibles include workforce in place, goodwill, and going concern value.
Second, it would allow the IRS commission to aggregate intangibles if that leads to a more
appropriate value. Finally, it would clarify that intangibles are to valued at their highest and best
as it would be by a willing buyer and seller with reasonable knowledge of the relevant facts. This
provision is projected to raise $1.2 billion for FY2011-FY2020.
Disallow Deductions for Reinsurance Premiums to Foreign Affiliates
U.S. insurance companies can reduce taxes by purchasing reinsurance from foreign affiliates,
with a deduction of the premiums by the U.S. firm but no tax on the income of the foreign
affiliate. This provision would disallow these deductions for reinsurance premiums when they are
more than 50% of the basic premiums received. This provision is contained only in the FY2011
budget and is projected to raise $519 billion in revenue from 2011-2020.
Earnings Stripping by Inverted Firms
The proposal would apply the provisions on earnings stripping discussed in 2004 to inverted
firms. For these firms the debt-to-equity safe harbor would be eliminated and non-guaranteed
related party debt would not be deductible when debt exceeded the 25% threshold. Carryforwards
of disallowed interest would be limited. This provision is projected to raise $3.6 billion for
FY2011-FY2020. The FY2011 provision appears broader than the FY2010 provision because it
covers debt paid to unrelated parties but guaranteed by a related party.
Prevent Repatriation of Earnings in Cross-Border Transactions
(Boot-Within Gain)

The plan includes a proposal to require that distributions that are characterized as reorganizations
but are in the nature of a dividend repatriation are subject to tax. This issue arises within the
framework of an exchange of stock on the one hand for stock and property (called “boot”) and
rules that provide the minimum of gain be based on the boot or overall gain. This proposal is
Congressional Research Service
42

Tax Havens: International Tax Avoidance and Evasion

projected to raise $297 million from FY2010 to FY2019. The 2011 budget includes a broader
provision regarding to boot in gain that covers domestic transactions as well, and such a provision
is also included in H.R. 4213.
Repeal 80/20 Rules (Enacted in P.L. 111-226)
This provision is related to dividends and affects individuals. Under current law, withholding is
applied to interest and dividends paid by corporations, but there is an exception for firms who
have 80% of their income from active foreign operations. This provision would repeal that
exception, raising projected revenues of $1.2 billion for FY2011-FY2020.
Foreign Tax Credits for Dual Capacity Taxpayers
This provision would disallow a foreign tax credit for taxes paid where there is an income tax that
is paid in part to receive a benefit (i.e., the firm is paying a tax in a dual capacity) unless the
income tax is generally imposed on the country’s own residents as well as foreign persons. The
current rule does not require the tax to be imposed on the country’s residents. This provision
typically relates to taxes being substituted for royalties in oil producing countries; there is a
provision that it will not abrogate any existing treaties. This provision was projected to raise $4.5
billion for FY2010-FY2019. The FY2011 budget has a slightly different provision that restricts
the tax credit to the amount that would be paid if the taxpayer were not a dual capacity taxpayer.
The FY2011-FY2020 revenue loss was $8.5 billion.
Provisions Relating to Individual Tax Evasion, Not Enacted in the HIRE Act
The President’s proposals included a number of provisions relating to individual evasion,
including reporting of information, withholding, and various penalties. Overall these provisions
were projected to raise revenues of $8.7 billion from FY2010 to FY2019 in the FY2010 budget
and $5.4 billion from FY2011-FY2029 in the FY2011 budget. Most of these provisions, or some
version of them, were adopted in the HIRE Act, including increased reporting on foreign accounts
(withholding and information on U.S. beneficial owners). The remaining provisions are
summarized below.
Reporting on Transfers
U.S. persons financial intermediaries and qualified intermediaries would be required to report
financial transfers. U.S. persons and qualified intermediaries would be required to report the
formation or establishment of a foreign entity. The floor is $10,000 in the FY2010 budget
proposal, but $50,000 in the FY2011 proposal.
Additional Information Reported on Tax Returns: Lower Floor
The HIRE Act required individuals who are required to file an FBAR (Foreign Bank and
Financial Account Reports) to report t his information on the tax return if the amount in the
account is $50,000 or more, a provision similar to the FY2011 budget proposal. The FY2010
proposal had a lower floor of $10,000.
Congressional Research Service
43

Tax Havens: International Tax Avoidance and Evasion

Burden of Proof and Presumption Provisions
The FY2010 proposal contains a number of provisions that provide evidentiary presumptions
(shifts in the burden of proof) in civil and administrative cases. If an individual has a foreign
account it is presumed to be large enough to require filing an FBAR. If a person has an account of
over $200,000 it is presumed that failure to file is willful (which opens the possibility of criminal
as well as higher civil penalties). If a payment subject to withholding is made to a foreign person
on an FDAP, the presumption is that that person is not eligible for withholding.
Statute of Limitation: No Floor
The statute of limitations for cross-border transactions is extended from three to six years with no
floor in the FY2010 budget proposal; in the HIRE Act and the FY2011 budget, it applies to
instances where more than $5,000 of income is omitted.
Stop Tax Haven Abuse Act, S. 506 and H.R. 126590
This bill has been introduced in the Senate by Senator Carl Levin and in the House by
Representative Lloyd Doggett. As with the President’s proposals, some of these provisions or
related provisions were included in the HIRE Act. Provisions in the Stop Tax Haven Abuse that
are addressed in the HIRE Act (P.L. 111-147)include burden of proof (Section 101), statute of
limitations (Section 104), information reporting on U.S. beneficiaries of foreign accounts (Section
105), trust abuses (Section 106), treatment of dividend equivalents (Section 108), and PFICs
(Section 109). Also, the health reform legislation included the economic substance doctrine. The
bill is summarized as introduced, including the provisions that have been enacted.
Section 101 would provide a burden of proof change. It would require the taxpayer involved in
offshore secrecy jurisdictions to produce evidence, based on the presumption that the taxpayer is
in control, that funds or other property are not taxable income, and that the account is not large
enough to trigger a reporting threshold. (The bill also addresses securities law issues.) This
section also contains the list of 34 tax haven jurisdictions taken from IRS court filings, and
provides Treasury with the authority to add or remove jurisdictions. An important standard for
being excluded from the list is an effective, and automatic, exchange of information.
Section 102 would expand the provisions in the Patriot Act of 2001, which gave Treasury the
authority to require domestic financial institutions to take special measures (including providing
information and prohibiting transactions) with respect to foreign jurisdictions relating to money
laundering to cover instances of impeding U.S. tax enforcement.
Section 103 would require a publicly traded corporation or one with gross assets of $50 million or
more whose management and control occurs primarily in the United States to be treated as a U.S.
company. This provision is directed at shell corporations, including hedge funds and investment
management businesses, set up in jurisdictions such as the Cayman Islands. It would not apply to

90 For a more detailed explanation of the bill see Senator Levin’s Introductory Remarks, March 3, 2009. This proposal
has also been discussed by Martin Sullivan, “Proposals to Fight Offshore Tax Evasion, Part 3,” Tax Notes, May 4,
2009, pp. 516-520.
Congressional Research Service
44

Tax Havens: International Tax Avoidance and Evasion

subsidiaries of U.S. corporations simply because some decisions are made at the parent
headquarters, but would still apply to shell subsidiaries.
Section 104 would extend the limit on audit periods from three years to six years for offshore
jurisdictions with secrecy laws.
Section105 would require U.S. financial institutions and brokers to file 1099 forms for any
foreign account when they know the beneficial owner is a U.S. person. It would also require these
institutions to report to the IRS when they set up offshore accounts and entities.
Section 106 addresses potential trust abuses. Foreign trusts have employed liaisons called trust
protectors as a way for shielding U.S. taxpayers exercising control over the trust; the legislation
provides that any powers held by a trust protector would be attributed to the trust grantor. It also
provides that any U.S. person benefitting from a trust is treated as a beneficiary even if not named
in the trust instrument, that future or contingent beneficiaries are treated as current ones, and that
loans of assets and property as well as cash or security are treated as trust distributions.
Section 107 addresses legal opinions, stating that an activity is more likely than not to survive
challenge by the IRS, which are used to shield taxpayers from large penalties. The legislation
provides that a legal opinion of this nature would not apply in an offshore secrecy jurisdiction,
providing exceptions to protect legitimate operations.
Section 108 would prevent dividend equivalents from escaping the dividend withholding tax.
Section 109 addresses reporting by passive foreign investment corporations (PFICs) by codifying
proposed regulations regarding PFIC reporting by direct or indirect shareholders who are U.S.
persons, and also requiring reporting by U.S. persons who directly or indirectly cause the PFIC to
be formed or sent or receive assets.
Some of the sections of title II of the bill affect securities law rather than tax issues. Some
provisions are tax-related, however.
Section 204 addresses an IRS John Doe summons where the IRS does not know the names of
taxpayers and now must ask courts for permission to serve the summons. This section provides
that in any case involving offshore secret accounts, the court is to presume tax compliance is at
issue, to relieve the IRS of the obligation when the only records sought are U.S. bank records, and
to allow them to issue John Doe summonses for large investigative projects without addressing
each set of summonses separately.
Section 205 would address issues relating to the Foreign Bank and Financial Account Report
(FBAR) requirement for a person controlling a foreign financial account of over $10,000. This is
a additional rule from the requirement to report this information on the tax return, and IRS is now
charged with enforcing this FBAR requirement. This provision would amend tax disclosure rules
to more easily permit IRS to use tax data, change the penalty to refer to the highest average in the
account during a year (and not on a specific day), and allow IRS access to information on
Suspicious Activity Reports (SAR).
The last title of the bill relates to abusive tax shelters, and contains several provisions. It would
strengthen penalties, prohibit the patenting of tax shelters, require development of an examination
procedure so that bank regulators could detect questionable tax activities, disallow fees
contingent on tax savings for tax shelters, remove communication barriers between enforcement
Congressional Research Service
45

Tax Havens: International Tax Avoidance and Evasion

agencies, codify regulations and make it clear that prohibition of disclosure by tax preparers does
not prevent congressional subpoenas, and provide standards for tax shelter opinion letters. It
would also codify the economic substance doctrine, to require both an objective and subjective
test for economic substance.
Finance Committee Proposal
A draft of this proposal was circulated on March 12 and has been discussed by Sullivan.91 Several
of its proposals were included in the HIRE Act (statute of limitations, requiring FBAR
information to be filed with the tax return, increasing trust penalties to a minimum of $10,000,
expanding the definition of distributions, and increasing the penalties for underpayments
associated with foreign accounts).
• It would require entities transferring funds offshore to report to the IRS the
amount, destination, and account information. Publicly traded companies would
be excluded.
• The statute of limitations would be extended from three to six years for tax
returns that report or should have reported certain international transactions.
• It would require the foreign bank and financial account report (FBAR) to be filed
with the tax returns.
• Tax preparers would be required to ask due diligence questions to determine
whether an FBAR should be filed.
• The foreign trust failure-to-file penalty would be increased to a $10,000
minimum and the definition of property considered to be a distribution for
foreign trusts would be expanded, and would include artwork and jewelry.
• Fines and penalties on payments attributable to certain offshore transactions
would be doubled.
• A provision in the Heroes Earnings Assistance and Relief Tax Act of 2008 (P.L.
110-245) would be modified to require offshore entities that hire workers under a
government contract be treated as American employers by establishing a rule that
any individual who performs at least 100 hours of service a month is an
employee and not an independent contractor.
Fraud Enforcement and Recovery Act, S. 386
This proposal, introduced by the Chairman Leahy of the Senate Judiciary Committee, includes a
provision to apply the international money laundering statute to tax evasion, and set aside funds
for the Justice Department to pursue financial fraud, including funds to the tax division. It has

Tax Havens: International Tax Avoidance and Evasion

Incorporation Transparency and Law Enforcement Assistance Act,
S. 569

This proposal would establish uniform requirements for states relating to the disclosure of
beneficial owners of corporations and limited liability companies, including updating and
maintenance of information after terminating, imposing additional requirements for those not
U.S. citizens or permanent residents, providing penalties, and updating of such disclosures. It also
authorizes a study of requirements of partnerships, trusts, and other legal entities. This bill is
relevant, among other things, to issues raised about the use of states as international tax havens.
The Bipartisan Tax Fairness and Simplification Act, S. 3018
This general tax reform proposal introduced by Senators Wyden and Gregg would, among other
changes, lower the corporate tax rate from 35% to 24%. Among the base broadening provisions is
a repeal of deferral and imposition of a per country foreign tax credit limit. The latter proposal
would prevent cross-crediting across different countries. The bill also includes withholding on all
foreign accounts, regardless of whether the account is considered by the foreign institution to
have a U.S. beneficiary, unless there is full information reporting.
