Mergers can be vertical (acquiring businesses in the supply chain), horizontal (with competitors
or related businesses), or conglomerate (with unrelated firms). There are business reasons for both mergers and divisions,
both aimed at increasing profitability.
A considerable body of research has been aimed at determining whether mergers increase profitability, whether that increase
is from gains in market power or increases in productivity, and reasons mergers might take place even if they do not increase
profits. While the findings are mixed, some evidence suggests that not all mergers are profitable and that, when they are,
increased profits may be due to market power rather than gains in efficiency. This issue is important because, while
efficiency gains are beneficial to society, gains in market power may benefit shareholders but harm the economy as a whole.
Divisions do not raise market power concerns, but a major tax concern is whether they are used to distribute profits in a tax-
favored way.
Mergers are estimated to account for about $2 trillion in value per year ($1.8 trillion in 2022); mergers of $1 billion or more
account for 75% of the value, although only about 2% of the number of mergers. There is relatively little information about
the size of divisions, but they appear to account for considerably less in value.
Mergers can be tax free if enough of the payment to the target corporation is in stock rather than cash or property and if
substantially all of the assets of the target corporation are acquired. Statutory guidelines are often general, and specific
guidelines are often in regulations. Divisions are tax free if they meet certain conditions designed to ensure that firms are
continuing the same business with the same historical stockholders and are not using the division as a device to achieve more
favorable tax treatment of distributions. Even in a generally tax-free reorganization, compensation in cash or property (called
“boot”) is taxable.
New taxes—such as the 15% corporate alternative minimum tax based on adjusted financial statement income and the 1% tax
on stock repurchases—generally apply the same tax-free rules as the regular tax system, as does the global minimum tax
(Pillar 2) proposed by the Organisation for Economic Co-operation and Development (OECD) and the Group of 20 (G20).
Because the minimum taxes apply only when a firm has an effective tax rate below 15% and only to large firms, they create
new tax consequences for mergers and divisions by changing the size of the firm and by blending or separating the minimum
tax rates of firm activities.
From a policy perspective, a reason for retaining tax-free treatment is to remove tax barriers to mergers, and a reason for
eliminating or restricting this treatment is to discourage mergers that mainly increase market power. Antitrust laws are a more
focused method of achieving the latter, but many analysts view them as too narrow and ineffective. Divisions have been the
focus of some relatively detailed proposals by academics, to simplify and reduce abuses.

Corporate Acquisitions and Divisions: Tax Issues

Introduction
Corporate reorganizations (mergers and divisions) are eligible in some cases for nonrecognition
of gains for tax purposes both at the corporate level and the shareholder level. The purpose of
these provisions is to facilitate reorganizations that continue the business in a different form but
with the same stockholders. A variety of restrictions apply to prevent abuse.
Mergers and divisions are also important for the new corporate alternative minimum tax
(CAMT), also referred to as the book income tax, and the new 1% tax on stock repurchases. They
are also an issue in the proposed global minimum tax under the Organisation for Economic Co-
operation and Development’s (OECD’s) Pillar 2. The CAMT and OECD minimum taxes, which
are based on a measure of financial income, only apply to large firms and only affect firms with
effective tax rates lower than 15%. They introduce new tax consequences for some mergers
because they alter the size of the firm. In addition, a merger of a firm subject to the tax with
another firm with a high effective tax rate can reduce the minimum tax paid. A division can
increase the minimum tax.
Companies merge and divide for business reasons, although taxes may be a consideration.
Mergers and acquisitions may be vertical (acquiring businesses in the supply chain, which may be
cost saving), horizontal (acquiring competitors or related firms), or conglomerate (acquiring
unrelated businesses). In some cases, mergers (primarily horizontal mergers) raise antitrust
issues.1 Companies may split up, for example, because some segments are mature and others are
growing, attracting different types of investors. Split-ups may facilitate more focused
management on each segment, and may make firm valuation more straightforward. Antitrust
issues have also led to some split-ups, as was the case with AT&T in 1984.
The first sections of this report discuss the consequences and magnitude of mergers and divisions,
and the remaining sections explain current tax treatment and issues and potential revisions that
may be of interest to Congress.
Causes and Consequences of Corporate
Reorganizations in Brief
Mergers have attracted more attention than divisions from the scholarly community, in part
because they raise issues of anticompetitive effects, largely with respect to horizontal mergers.2
Mergers can increase productivity by increasing economies of scale or providing improved
products, which are beneficial to society. Mergers may also increase profits because of increased
gains from market power, which is beneficial to shareholders but harmful overall to society.3
Mergers may also fail to increase profits for a variety of reasons, for example by creating
“diseconomies” of scale such as increasing the cost and difficulty of coordination. Research on

Corporate Acquisitions and Divisions: Tax Issues

mergers has addressed three issues: whether mergers increase profits, whether any increased
profits are due to efficiency gains or exercise of market power, and reasons mergers might take
place even if they do not increase profits. There is some dispute about whether mergers create
value, although there is more agreement that a cash merger (where the firm is acquired for cash)
is more likely to create value than a stock merger (where a firm’s shareholders receive stock in
the acquiring firm as compensation) in the long run.4 A study by researchers at the Federal
Reserve found that, in general, mergers resulted in increased profits because of monopoly power
rather than efficiency gains.5 Other researchers have made the case that mergers may create
negative value but may increase compensation of executives.6 Mergers have sometimes come in
waves and concentrated in certain industries, and there is evidence that these waves may be due
to shocks to the industry, particularly deregulation, as in the case of airlines.7
As discussed subsequently, taxes can discourage mergers (through taxation of cash payments) or
encourage them (through acquiring firms with net operating losses), although one source of tax
benefits—corporate inversions—has decreased in importance in recent years through tax law
changes.
Divisions have generally not been subject to this degree of study and, in general, studies find that
they enhance economic performance.8 Some divisions spin off previous acquisitions; the major
reasons cited in a survey include to increase focus or to divest a low-performing division.9 Tax
issues, however, have been more central to concerns about divisions as a device to distribute cash
to shareholders in a tax-favored manner.
The Magnitude of Mergers and Divisions
Several organizations track data on the size of mergers, whereas data on divisions are limited.
Although mergers or breakups of large firms are in the news, these types of reorganizations also
involve small corporations which are probably not counted in most data.

destroy value.

Corporate Acquisitions and Divisions: Tax Issues

Mergers and Acquisitions
The value of mergers and acquisitions in 2022 was $1.8 trillion, down from $3.1 trillion in 2021
(corresponding to 21,000 and 25,000 mergers and acquisitions, respectively).10 The numbers for
2021 represented an unusually high year. The contraction in 2022 is also ascribed to the mid-year
increase in interest rates. About 75% of the value in the last two years ending on March 31, 2023,
was for mergers with values of $1 billion or more, and mergers were particularly pronounced in
the technology and financial industries.11 These $1 billion or more deals accounted for less than
2% of mergers, although there was a disproportionately high number of mergers in the same
industries.
According to another source, there was $3.8 trillion in global mergers in 2022, with U.S.
companies involved as either a target, acquirer, or both, accounting for 53% of merger value.
Purely domestic accounted for 34.7% of merger value, U.S. acquirers of foreign firms was 10.6%,
and foreign acquirers of U.S. firms was 7.7%.12 Of the top 10 global mergers by value in 2022,
U.S. domestic mergers accounted for 6 and U.S. acquirers accounted for 7.13
Both acquirers and targets of firms in mergers and acquisitions can be corporate or passthroughs,
and in the case of acquirers, financial investors. Several types of entities can make acquisitions:
existing corporations, private equity firms, financial investors, venture capitalists, and special
purpose acquisition companies (SPACs).14 The majority of acquirers are corporations, although
this share varies over time.15 While this discussion focuses primarily on corporate
reorganizations, there are also rules that apply to partnerships and other flowthroughs.
An issue that is particularly important for tax purposes is whether the acquisition involved a
transfer of stock, rather than a cash purchase.16 Data indicate that stock is typically involved in
about 30% of recent transactions (2017-2022).17 A study of earlier transactions found that stock
was involved in 65% of transactions from 1985-2015.18 Cash may have recently been preferred
because of low interest rates, if funds are borrowed to make the purchase. In general, cash

Corporate Acquisitions and Divisions: Tax Issues

purchases are also preferred when an acquirer is closely held and shareholders do not want to lose
control, or when the acquirer has a lot of free cash flow, reducing the need for borrowing. Cash
transactions go faster and fall through less often. Cash is less likely with a large acquisition. Stock
deals may be more likely when acquirer stock is overvalued because stockholders can exchange
their overvalued stock for the stock of the target (acquired firm), although one study found that
these acquisitions were motivated by CEO compensation.19
Divisions
Although breakups of large companies are in the news, smaller business also break up. One data
source indicated that in the past decade there were $624 billion in new companies created in
divisions, suggesting that these reorganizations are less important than mergers.20 Breakups have
increased recently, so this number may be larger. Some very large firms have recently completed
or announced breakups (e.g., Johnson and Johnson, General Electric, and Kellogg).21
One reason for corporate splits is that investors prefer firms with more focus, which can allow
shareholders to avoid a “conglomerate” discount. One study of spin-offs between 2005 and 2015
estimated that spin-offs gained firms over $200 billion in increased value.22
Mergers and divisions are related. Some breakups have resulted from prior conglomerate
acquisitions that did not perform as well as expected; one source reported that 44% of mergers
subsequently led to divestitures.23 At the same time, firms that have spun off are likely to make
acquisitions in the years shortly after the spin-off, and perhaps that is a motive for splitting off
parts of the company. One study found that over 50% of firms that broke up cited future
acquisition as a motive for the spin-off and 78% of spun-off firms made acquisitions within five
years.24
How Mergers and Divisions Are Taxed Under the
Income Tax
Mergers and divisions may qualify for tax deferral if they meet certain conditions. In general, this
deferral is available only if securities are exchanged; any cash or similar payments (boot) is
subject to taxation.

Corporate Acquisitions and Divisions: Tax Issues

A Note on Basis and Boot
Two concepts that are important to understanding the tax treatment of mergers and divisions are
basis and boot:
• Basis is the value of property which determines the value for depreciation
deductions or the amount excluded as a return of capital (and not subject to
capital gains) when an asset is sold. Basis is generally what is paid for the asset,
reduced by any depreciation deductions for physical assets. Depending on how
the transaction is treated, basis may be the original basis in the hands of the
acquired firm or the fair market value at the time of the transaction.
• Boot is the amount received in a transaction that is in cash or property, rather than
securities. Boot is subject to tax even in generally tax-free transactions.
Mergers and Acquisitions
This section explains the general tax rules that apply to taxable acquisitions and the special rules
that allow non-taxable acquisition.
Tax-free treatment of reorganizations that involve an exchange for securities dates back to 1918
and is thus a long-standing part of the tax code. The early rationale for this treatment was that it
prevented taxation on what is essentially a paper transaction. At the time, proponents also argued
the treatment was needed to encourage or at least not hinder beneficial changes in business
organizations and economic growth after World War I. It was also justified as simplifying
administration and compliance, including the liquidity problem if shareholders are subject to tax
but do not receive the funds to pay the tax.25
Note that the type of transaction determines the basis of assets or stocks, and therefore for
determining depreciation or capital gain if the asset or stock is sold.
Taxable Acquisitions
Acquisitions are of three basic types: a purchase of stock, a purchase of an asset, or a merger that
takes place under state law (statutory merger). The parties are the purchaser (the acquiring firm),
the target, and in some cases a subsidiary of the purchaser.
Note that under a general rule (Section 1032 of the Internal Revenue Code [IRC]), a corporation
does not recognize gain in providing stock in return for assets (issuing stock). That is, when a
corporation issues stock and sells it for cash to shareholders, no gain is recognized.
• Stock Purchase: In a stock purchase, the purchaser buys stock from the target’s
shareholders. The target’s shareholders are subject to a capital gains tax and there
are no tax consequences at the corporate level. The purchaser simply owns shares
in the target company. To have control, it must purchase enough stock.
• Asset Purchase: In a purchase of assets, the purchaser exchanges its cash,
property, or stock for some or all of the assets of the target. The purchaser can
avoid taking on any undesired liabilities by purchasing only selected assets of the
company. Cash and property are called boot and the entire purchase price can be
in cash. The target company pays tax on the difference between the purchase

price (including any liabilities assumed) and the target’s basis. The purchaser’s
basis is the fair market value of the assets. To the extent that shares are used to
purchase assets, shareholders of the target receive shares of the acquiring
company. Cash may be used by the target company to repurchase shares or make
cash payments. If the target company is liquidated, its shareholders pay capital
gains tax. If the company continues, a stock redemption or repurchase is taxed as
a capital gain, and direct cash payments to the target’s shareholders are taxed as a
dividend.
• Statutory Merger: In a taxable merger, the two firms are combined and the
target does not survive. State laws guide statutory mergers, which generally
require shareholder approval. The merger can be taxed as an asset purchase in the
case of a direct merger of the target into the purchaser or the merger of the target
into a subsidiary of the purchaser (called a forward triangular merger). The
merger can also be treated as a stock purchase if a subsidiary of the purchaser
merges into the target (the target receives consideration for its stock, and the
subsidiary’s stock is converted to new target-issued stock, called a reverse
triangular merger). Mergers using a subsidiary have the advantage of shielding
the parent from any unknown liabilities.
Under IRC Section 338, an election (i.e., a 338(g) election) can be made to treat a stock purchase
as an asset purchase, which means that the target pays tax on the gain of the deemed asset sale
and the purchaser has a new basis as the fair market value of the assets. This election might be
beneficial if the target has net operating losses to offset the tax and depreciation for the purchaser
increases due to the higher basis. (A stock acquisition generally preserves the preexisting
attributes of the firm, such as net operating losses, while an asset acquisition does not.) A Section
338(h)(10) election can also avoid tax at the shareholder level if the acquired corporation is a
subsidiary of another corporation.
Section 351 Transaction and Section 357 Debt Assumption
Section 351 provides that a transfer of property to a corporation in exchange for stock will not be
taxed if after the transaction the transferor is in control of the corporation (the transferor must
have at least 80% voting stock and other stock). Gain will not be recognized and the basis of the
property will generally be the same in the corporation’s hands. If boot is received from the
corporation, it will be taxed up to the amount of gain on any appreciated property and basis may
be adjusted. This section might be used to form an initial corporation or to create a subsidiary and
is thus not so much a merger as a change in organizational form.
If debt is assumed by the corporation, it is treated as boot and a tax will apply up to the gain (this
rule is in Section 357). Because of the rule treating the transfer of debt in excess of basis as
taxable income, unincorporated businesses that become corporations by swapping the business’s
assets for stock in the corporation may generate a tax liability if they have debt and a low basis in
assets.
Tax-Free Acquisitions
The rules for tax-free treatment for both acquisitions and divisions are generally contained in Part
III of Subchapter C of the IRC, in Sections 354-368. They relate to both the treatment at the
corporate level and the treatment at the shareholder level and apply to reorganizations as defined
in Section 368. If the reorganization qualifies for the tax-free reorganization rules, taxes are
deferred on some gains.
Congressional Research Service

Corporate Acquisitions and Divisions: Tax Issues

Sections 354, 356, and 358 govern the treatment of the target’s shareholders. Section 354
provides that gain or loss will not be recognized to the target’s shareholders if the reorganization
is the exchange of stock. (Section 355 relates to divisive reorganizations.) Section 356 provides
that when some money or property (boot) is received, the recipient will be taxed on the boot up to
the amount of gain. Section 358 provides that the shareholder’s basis will remain the same.
Sections 361-362 govern the treatment of tax in an asset purchase. The target is not subject to tax
on appreciation of assets and the purchaser takes on the target’s basis in the asset in a qualified
reorganization.
Section 368 defines the term “reorganization” and in the process lays out a series of rules
governing types of reorganizations that qualify for tax-free treatment in Section 368(a)(1). The
treatment is not always completely tax free, as stockholders of the target corporation may pay
some tax. This section lists seven types of reorganizations, A-G. All of these apply to acquisitions,
but type D can also apply to divisions. E, F, and G are specialized. E and F involve only one
company, in E exchanging one type of security for another (e.g., bonds and stock), and in F
changing the company’s name, location, etc. G relates to corporations in bankruptcy.
• Type A: This type is a statutory asset acquisition merger that takes place under
state laws, which generally require shareholder approval by at least a majority
vote. The purchaser acquires all of the target’s assets and liabilities. Among other
requirements, it has a continuity of interest requirement to receive tax-free
treatment, which has been determined by the Internal Revenue Service to require
at least 40% of the payment to the target for its assets to be in the form of stock
of the purchaser. In a qualifying merger, there is no tax on the target corporation
(Section 361) as long as property received is distributed, and the purchaser keeps
the original basis (Section 362), the stockholders of the target pay tax on the
lesser of boot or gain (Section 356), and they retain their basis in the target
company stock (Section 358). Forward triangular mergers and reverse triangular
mergers are also allowed under Sections 368(a)(2)(D) and (E), although reverse
triangular mergers require that stock constitute 80% of the compensation.
• Type B: This merger exchanges stock of the purchaser for stock of the target,
with the purchaser controlling the target after the merger. No boot is allowed, and
no taxes are incurred at either the firm or shareholder level. A Section 338
election is not allowed.
• Type C: This merger is also an asset acquisition, but the purchaser does not have
to acquire all of the target’s assets and liabilities. The requirement, under an IRS-
created safe harbor, is to purchase at least 70% of the gross assets and 90% of the
net assets; lesser amounts may qualify depending on the facts and circumstances.
The purchaser must provide consideration of at least 80% voting stock. (If the
target has substantial liabilities that are assumed, 100% of the payment in voting
stock may be required.) The target distributes stock, compensation, and any
remaining assets to shareholders. Tax treatment is the same as a Type A merger.
This type of merger allows firms to avoid certain liabilities of the firm that may
be uncertain.
• Type D (Acquisitive): This merger is similar to C, but the voting stock
requirement does not apply. However, after the merger, the target corporation’s
shareholders must own more than 50% of the stock of the purchasing corporation
(i.e., they control it), which would require use of voting stock to achieve that
purpose. (This plan is also qualified under Section 354.)

Corporate Acquisitions and Divisions: Tax Issues

• Type E: An E reorganization is not a merger but an exchange by a corporation of
one type of security for another (i.e., a “recapitalization”).
• Type F: An F reorganization is not a merger but a change of identity, form, or
place of organization.
• Type G: Type G relates to a merger in a bankruptcy proceeding, where assets are
distributed to shareholders in a transaction that otherwise qualifies for tax-free
treatment.
Asset purchases that are eligible for tax-free treatment also carry over attributes of the target firm,
such as net operating losses. These attributes are listed in Section 381(c), although the rate at
which net operating losses are taken into account is limited under Section 382. This limit is based
on a rate of return multiplied by the target’s assets.
Special Rules for International Mergers26
Transfers of property to foreign corporations in a merger are subject to tax under Section 367.
This rule applies because once transferred, the property can be sold and otherwise escape U.S. tax
indefinitely. A special provision for the transfer of intellectual property provides for ordinary
income tax on a stream of payments representing the asset’s earnings.27
Until 2006, type A mergers were not available for international mergers because they had to take
place under state law; regulations subsequently extended type A mergers to foreign transactions.28
Before that time, international asset mergers were largely limited to type C reorganizations, which
are more restrictive as to the form of payment made for property (that is, stricter limits on the
amount of boot).
One tax motive for international mergers—allowing firms to change headquarters to take
advantage of lower tax rates, called inversions—has been restricted through several tax code and
regulatory changes beginning in 2004, when the tax code was revised so that any inverted firm
where the U.S. shareholders owned 80% or more of the combined firm would be treated as a U.S.
firm. Any 60% to 80% mergers would not be allowed to use net operating losses or foreign tax
credits to offset the tax. These changes meant that there was an incentive to merge with a foreign
firm in order to achieve the inversion. This motive is not related to the direct tax treatment of
mergers as much as other characteristics of the international tax system.29
Current Requirements and Limitations of Tax-Free Acquisitions
In addition to the statutory requirements, there are other conditions arising from court decisions
or regulations. The purpose of these conditions is to ensure that the historical shareholders of the
target firm continue to have an interest in the same business and that the merger not be equivalent
to a sale. There are basically four requirements.30

Corporate Acquisitions and Divisions: Tax Issues

Continuity of Interest
Continuity of interest concerns arose in court cases, and detailed conditions regarding continuity
of interest are in the regulations, which include the basic requirement that 40% of the
consideration received by the target shareholders is in the form of stock of the acquiring
company. There has been a continuing issue about whether and under what circumstances the
target shareholders could subsequently sell their shares while maintaining tax-free treatment, but
current regulations do not impose any requirement and probably could not do so for widely held
firms whose stock is frequently traded.
Continuity of Business Operations
The acquiring corporation must continue to operate a historical line of business of the target or
use a significant portion of the target’s assets in business. The examples given in regulations
suggest that operating one of three historical lines of business or using a third of the assets will
meet the qualifications.
Business Purpose
The acquisition must have a business purpose outside of benefitting shareholders. This test is
generally easily met.31
Subsequent Transfers of Assets
Generally, assets cannot subsequently be transferred outside of the corporate group, although
there can be transfers if they do not cause the continuity of interest test not to be met.
Divisions
Distributions in General (Without Tax-Free Treatment)
Tax on Corporations
In general, a distribution of stock of a corporation to its shareholders does not result in a tax to the
corporation, but a distribution of appreciated property (including stock of other corporations) is
subject to a tax on the gain at the firm level. This treatment means that for a distribution of
appreciated property, the tax treatment is the same as if the firm sold the property and distributed
cash. Treatment of corporations is contained in IRC Sections 311-312.
Tax on Shareholders
The tax rules for shareholders are contained in IRC Sections 301-307.
A distribution of a corporation’s stock is not income to shareholders and a distribution of property
is taxed as a dividend. If the dividend exceeds the earnings and profits of the corporation, any
excess reduces the basis of stock, and any additional excess is taxed as a capital gain.

Corporate Acquisitions and Divisions: Tax Issues

If a corporation redeems (or repurchases) its stock, the shareholder is treated as if the stock were
sold and taxed as a capital gain (the purchase price less the shareholder’s basis), unless it is
considered equivalent to a dividend. A series of provisions addresses circumstances where the
distribution is not treated as a dividend. For example, a series of cash payments that redeems a
portion of each shareholder’s stock could be a dividend, whereas a purchase of shares in the open
market would be a capital gain. Since capital gains and dividends are currently taxed at the same
rates, the advantage of capital gains treatment is that tax applies only to amounts in excess of the
basis (original cost to the shareholder). If the redemption is liquidation of a firm, the distribution
is treated as a capital gain.
Separating a Business When Taxable
Under these rules, without the special tax-exempt provisions under IRC Sections 355 and 368, the
following results would occur if a firm wished to separate into two businesses.
If the business is not contained in an existing subsidiary, the firm can distribute assets to
shareholders, which results in a tax to the corporation on gain and a dividend to shareholders.
(This approach would only work in a closely held corporation.) Alternatively, it can sell the assets
directly, pay capital gains tax, and then distribute cash to stockholders, who pay tax on the
dividend.
A firm can create a subsidiary without tax consequences if it exchanges property solely for the
shares of the corporation (Section 351) as long as it is in control of the subsidiary (at least 80% of
the voting stock and at least 80% of all other stock). If it receives cash or property (boot), it is
subject to tax on the boot up to the amount of the gain.
If the firm has a subsidiary or creates a subsidiary, it can sell shares in the subsidiary to the
public, pay gain on the stock sale, and distribute cash to shareholders as a dividend. Alternatively,
assuming it does not qualify under Section 355, it can distribute the stock to shareholders or
exchange the stock for stock of the distributing firm, and the general rules for tax on distributions
apply (dividends treatment on a distribution of stock and capital gains on an exchange of stock).
Tax-Free Divisions (Qualifying Under Section 355)
The purpose of a tax-free division, in general, is to allow a division of a business among existing
shareholders, so that those existing shareholders as a group continue to own the firm (although
these shareholders may have different ownership of different parts of the firm). A firm can
transfer stock of a subsidiary to its shareholders tax free if it meets the requirements of Section
355. If it already has a subsidiary, the rules of Section 355 apply (i.e., no tax to shareholders and,
in exchanges, shareholders allocate basis between the shares proportional to market value for the
purpose of future sales). The firm can also create a subsidiary under Section 368(a)(1)(D) and
immediately distribute the stock under a plan of reorganization that meets the requirements of
Section 355 with no tax to either the firm or the subsidiary. In general, gain is not recognized to
the corporation for subsidiary stock, subsidiary securities, or boot if boot is passed on to
shareholders or creditors under certain circumstances. If assumed liabilities exceed the basis in
the asset, gain will be recognized, and if boot exceeds the basis of the assets minus debt assumed,
boot will be taxed to the firm. The firm must own 80% or more of the shares of the subsidiary
before the distribution and shareholders must own at least 80% after the distribution.
Distributions fall into three types.
Congressional Research Service

Corporate Acquisitions and Divisions: Tax Issues

Spin-off
In a spin-off, the firm distributes stock of the subsidiary to its shareholders on a pro rata basis.
Shareholders allocate existing basis between parent and subsidiary shares based on fair market
value. If boot is included, it is taxed as a dividend.
Split-off
In a split-off, the corporation distributes shares of the subsidiary to its shareholders in exchange
for its own stock. It does not have to be pro rata. Any boot is treated as a stock redemption
(subject to capital gains tax).
Split-up
The firm creates two subsidiaries and distributes the shares to shareholders, with the parent
company liquidated. Boot is taxed as a stock liquidation (capital gains).
Current Requirements and Limitations of Tax-Free Division
The tax-free division is designed to allow a business to be separated into parts while still
maintaining control by its existing shareholders. To qualify as tax free, a number of conditions
must be met, some in the tax code and some in regulations, as many of the conditions are general
in nature.32 Most of the requirements in Section 355 were long-standing, dating from spin-off
rules that were first adopted in 1924, and then rescinded in 1934 over concerns that the provisions
allowed shareholders to convert dividends into capital gains. Spin-offs were once again allowed
in 1951, but with provisions that the active trade or business must be carried on and the division
not be used as a device for distributing earnings and profits (the device restriction). In 1954, a
control test was added, and the provision was largely unchanged until the elimination of a general
ability to transfer appreciated assets to shareholders without paying a corporate-level tax (referred
to as the General Utilities doctrine) in 1986.33 This repeal led to a series of related reforms to
Section 355. One article suggests that the combination of taxing dividends at the same rate as
capital gains and the repeal of General Utilities means the focus of abuse in Section 355 moves

32 Several articles discussing the history and issues associated with Section 355 provide additional background. Michael

355 and proposes reforms. In addition to these articles that analyze legal principles, articles that discuss the rules

from a concern about transforming dividends into capital gains treatment (the focus of the device
restriction) to not allowing it to be used to avoid the General Utilities repeal.34
Some requirements are statutory and some are contained in the regulations. The first two are in
the regulations, and the remainder in the statute, although also addressed in more detail in
regulations.
Business Purpose
The regulations specify that Section 355 applies only if the division is carried out for a business
purpose.35 This provision is defined in the regulations following a Supreme Court decision in
1935 that found it was not sufficient for a division to meet the statutory requirements for tax-free
treatment, but there must also be a business purpose.36 While business purpose is not precisely
spelled out in the regulations, examples given include separating a risky from a less risky
business, or separating into businesses that different shareholders want to focus on, leading them
to be more efficient.
Continuity of Interest
These regulations also require that the shareholders of the original corporation must retain
interests in both corporations after the distribution, that is, neither corporation can be immediately
sold after the distribution. The preexisting stockholders must maintain some minimum equity
interest. There is no specific bright line in the regulations, although examples indicate that 20% is
not enough and 50% is enough to satisfy the requirement. There is also no specific time period for
these requirements, although the Internal Revenue Service has indicated that five years would be
sufficient, while advisors suggest two years, and courts have allowed periods shorter than two
years.
Control
Corporations are required to be in control (80% of voting power and 80% of all other shares) of
the subsidiary before the distribution of stock or the exchange of stock, and shareholders are
required to be in control after the distribution.
Device Restriction
The distribution must not be used as a device to distribute earnings and profits. This provision
relates to the historic concern that led to spin-offs being disallowed in some periods in the early
tax law, because of the use of spin-offs to make distributions that were dividends, with money
then realized by selling the stock with a capital gains treatment. This rule was more important
when dividends were not taxed at favorable capital gains rates. Capital gains treatment remains
beneficial since basis is deducted from capital gains but not dividends.
The test is a subjective facts and circumstances test with standards in the regulations, and it
weighs the factors for and against a device. Factors indicating a device include a pro rata
distribution of stock, a sale of stock after the distribution, assets not used in a five-year trade or
business, and a secondary business that could be sold without adverse effects. Evidence against a

device includes a strong corporate business purpose, stock of the company is publicly traded and
there are no shareholders with more than a 5% share, and shareholders are corporations that
would be entitled to a dividends-received deduction.
The device test is aimed at the treatment of distribution to shareholders and adopted prior to the
repeal of the General Utilities doctrine.
Active Business Requirement
Both the distributing firm and its subsidiaries must carry on an active trade or business after the
division. This active trade or business must have been carried on for the five years preceding the
division (included in this amount is the purchase of a business in the same line, the business
expansion rule). The trade or business could not have been acquired in the previous five years by
a taxpayer who recognized gain. Control of the corporation could not have been acquired by a
distributee (shareholder) corporation or the distributing corporation within five years where gain
or loss was not recognized. This last requirement was put in its current form in 1987 (Section
355(b)(2)(D)). This change was to prevent a firm from recently purchasing the distributing firm
for cash (and thus having a high basis) and then allocating part of that basis to subsidiary stock in
a spin-off and selling the shares while recognizing little or no gain.
Part of the active business requirement’s purpose is to prevent businesses from separating their
inactive businesses (such as holding of stock and securities) from their active business. There has
been concern about the active business being a de minimis part of total assets (5% or even less),
and proposed regulations in 2016 provided some specific rules as to what ownership shares would
be considered as evidence of a device or as evidence of a nondevice.37 These regulations proposed
a minimum of 5% of active business assets. In addition, evidence that there is no device would be
if both the distributing and controlled corporation each had 20% nonbusiness assets or if the
difference between the two was less than 10 percentage points. Evidence of a device would be if
two-thirds of assets were nonbusiness or if there were certain disparities between the shares of the
distributing and controlled firm.38
Disqualified Distribution
This provision (Section 355(d)) was added in 1990 after the repeal of General Utilities, and
expanded the scope of circumstances where corporation-level tax is imposed after the 1987
revision. It imposes tax on the gain to the corporation on a distribution if, immediately after the
distribution, a shareholder holds a 50% interest in either the distributing or the controlled
corporation that is attributable to stock purchased within the five-year period before the
distribution. Subsequent regulations are argued to have significantly limited the scope of Section
355(d).39

Corporate Acquisitions and Divisions: Tax Issues

Morris Trust Rule
Section 355(e) was added in 1997 to address transactions where the spin-off is followed by the
acquisition of 50% of the distributing corporation (Morris Trust transaction) or of the spun-off
corporation (reverse Morris Trust transaction) by another corporation.40 Under this section, gain
will be recognized at the corporate level if the acquisition takes place within two years before or
after the spin-off, although this treatment can be rebutted (called a rebuttable presumption). There
are a number of complex regulations governing whether Section 355(e) applies. While these
provisions followed highly publicized transactions, some critics argued that this type of
transaction was the only way to eliminate unwanted businesses when two corporations decide to
merge. Section 355(f) disallows tax-free treatment of shareholders in an intragroup transaction if
Section 355(e) applies.
Section 336(e) Election
A provision was added in 1986 authorizing the Department of the Treasury to prescribe
regulations to allow a parent corporation to elect to treat certain sales and dispositions of stock in
a subsidiary as a sale of assets, so gain would be recognized and basis would be increased. This
election is relevant to divisions that fail to qualify under Section 355, or fail to qualify for
nonrecognition of gain under the disqualified distribution rule (Section 355(d)) or the Morris
Trust rule (Section 355(e)). This rule can prevent multiple levels of tax, when the distribution is
made (because of failure to qualify for tax-exempt treatment) and if the assets are subsequently
sold.
“Cash Rich” Corporations
This provision (Section 355(g)) was added in 2005 and disallowed Section 355 treatment when
either the distributing or controlled corporation had more than two-thirds of the assets in
investment assets, and one shareholder controls at least 50% of the value.
Real Estate Investment Trusts
A provision (Section 355(f)) was added in 2015 to disallow Section 355 treatment for distributing
or controlled corporations that became real estate investment trusts (REITs). REITs are not
generally taxed at the corporate level.
Corporate Reorganizations and the 15% Corporate
Alternative Minimum Tax
The Inflation Reduction Act of 2022 (P.L. 117-169) imposed a corporate alternative minimum tax
(CAMT) based on financial statement income.41 The minimum tax is 15% of financial income
adjusted in a number of ways, and firms pay the larger of the minimum tax or the regular tax
imposed at a 21% rate.42 It is limited to larger corporations with an average of $1 billion or more

in earnings over a three-year period. A number of adjustments to financial statement income were
made in the statute, which also provided broad authority to the Secretary of the Treasury to
prescribe regulations.
One issue not addressed in the statute was the treatment of corporate reorganizations. Corporate
reorganizations raise two concerns: (1) the recognition of certain income in reorganizations for
financial but not for tax purposes; and (2) how changes in ownership should be considered for
purposes of defining firms subject to the tax.
Preliminary guidance issued in December 2022 indicated that financial statement income would
be adjusted to eliminate the recognition of income or a change in basis that does not conform to
the tax laws on corporate reorganizations. The treatment of boot is unresolved and will, according
to the preliminary guidance, be addressed subsequently.43
The second issue is how mergers and divisions affect the determination of whether a corporation
is subject to the CAMT, referred to as an applicable corporation. The general rule is that once a
corporation becomes subject to the CAMT, it continues to be subject to it. There are exceptions
for cases where the firm subsequently does not meet the test, as determined by the Secretary of
the Treasury. In addition, there is an exception if ownership changes.
The December 2022 guidance indicates that when a firm acquires a stand-alone target that is an
applicable corporation, the target is no longer an applicable corporation and the acquirer takes
into account the financial statement income of the target for determining whether it is an
applicable corporation under the three-year test. When a firm acquires part of another firm, the
financial statement income of the target is included in both the acquirer’s and the original firm’s
financial income for the three-year test. Similarly, in a division where a controlled corporation is
distributed to the parent’s shareholders, the financial statement income of the controlled
corporation is included in both the parent’s three-year test and the spun-off firm’s. The regulations
do not address methods of allocating financial statement income in mergers and divisions.44
The nature of the minimum tax means that mergers and divisions have additional potential tax
consequences. A merger, for example, could create a larger firm that would be subject to the
CAMT, while a division might cause the firm to no longer be subject to it. A merger of a firm
subject to the CAMT with a firm that has a high effective tax rate will reduce any minimum tax
due, since the income and taxes will be combined. For example, if two firms of equal size merge,
one with a 10% effective tax rate (thus paying 5% of income as a tax) and one with a 20%
effective tax rate, the overall tax rate becomes 15% and no CAMT is due. A division could
generate higher minimum taxes if one portion has low tax rates and another high tax rates. For
example, a firm with an effective tax rate of 15% that splits into two businesses of the same size,
one with a 10% tax rate and one with a 20% tax rate, will be subject to an additional tax rate of
2.5% of the combined profits.

Corporate Acquisitions and Divisions: Tax Issues

The 1% Tax on Corporate Stock Repurchases
The Inflation Reduction Act (IRA) also included a 1% excise tax on stock repurchases by
publicly traded corporations.45 President Biden and several Senators have proposed to increase
the rate to 4%.
The law specifically excludes tax-free corporate reorganizations outlined in Section 368(a) of the
IRC, which include mergers, acquisitions, divisions, and other forms of reorganization. In tax-
free reorganizations, gain is not generally recognized when compensation is in stock (e.g.,
shareholders of the target company in an acquisition redeem their stock for stock of the acquiring
company). Gain is recognized to the extent shareholders are compensated in cash or other
property (boot).
Commentators raised two issues about the effect of the tax on reorganizations. One was whether
reorganizations will be completely exempt from the tax, or only stock compensation and not boot
will be excluded. The other concern is certain split-offs that are governed by another section of
the tax code, Section 355. Divisions can take place under either section and constitute the same
type of distribution, but the IRA only refers to Section 368. Divisions can take place as spin-offs
(where stock of a subsidiary is distributed pro rata to the shareholders), which does not involve a
repurchase. However, divisions can take place as split-offs where the subsidiary’s stock is
exchanged for the parent company’s stock, which may also involve payment of cash or property
(boot).
Interim regulations and examples clarify that the exception for tax-free reorganizations under
Section 368 excludes stock transferred in these reorganizations from the tax but not any boot that
is exchanged for stock and subject to gain. For example, if part of the payment for the stock of a
target is cash and part is in acquirer stock, the share that is cash will be subject to the excise tax as
a repurchase by the target. It also confirms that Section 355 split-ups are subject to the exclusion
as well.46
Implications of the OECD/G20 15% Minimum Tax
(Pillar 2)
The OECD/G20 has proposed a global minimum tax of 15% that will be imposed on financial
income under Pillar 2 of its two-pillar solution to internal base erosion and profit shifting.47 A
number of countries are in the process of adopting the rules, including member states of the
European Union, the United Kingdom, South Korea, Japan, and Canada. The tax applies to
companies with global revenues exceeding €750 billion (equivalent to about $810 billion based

on August 22, 2023, exchange rates) in at least two of the four fiscal years preceding the current
fiscal year. The OECD/G20 global minimum tax is referred to as GLoBE.
Top-up taxes will be applied to raise the effective tax rate on financial income to 15%. The right
to levy a top-up tax goes first to the country where the firm is located through a qualified
domestic minimum top-up tax (QDMTT). If the country of location does not impose a top-up tax
on income earned in the country, the home country of the parent company can collect the tax
through the income inclusion rule (IIR) by increasing the income of the parent subject to tax. If
neither of these taxes apply, then countries where other constituent entities (such as subsidiaries
and branches) are located can collect the tax by denying deductions for those constituent entities
through the undertaxed payments rule (UTPR). This latter rule is often referred to as the
undertaxed profits rule.
In general, a reorganization under the GLoBE rules will not result in immediate taxation of gain if
the reorganization is a GLoBE reorganization.48 A GLoBE reorganization is one where all or a
significant portion of consideration for the transfer is in stock and where the gain is not taxed.
Thus, GLoBE will generally allow tax-free reorganizations in the same way as under the U.S.
corporate tax.
The OECD guidelines indicate that for application of the threshold and the four-year test,
financial income of entities that merge will be combined for prior years to determine applicability.
For divisions, the threshold is based on the financial income for each entity. For the first year
after the division, the threshold will be based on the current revenues. For the second through the
fourth years, it will be based on any two years that meet the threshold.
As with the CAMT, GLoBE will lead to additional tax consequences for mergers and divisions. It
is currently unclear whether or when the United States will enact rules complying with GLoBE,
but even if the United States takes no action, its firms can be taxed under other countries’ IIRs or
UTPRs. GLoBE will likely be more far reaching than the CAMT because of the lower threshold.
While many mergers will be tax exempt or partially tax exempt, reorganizations may cause firms
to be subject to GLoBE through a merger, or no longer subject to the tax through a division. Also,
as is the case with the CAMT, a merger by an affected firm with a target that has a high effective
tax rate can reduce the amount of GLoBE tax paid, while a division can increase it.
GLoBE might also favor acquisition of companies by private equity firms rather than other firms
because GLoBE does not count income and taxes paid by portfolio companies as part of
consolidated income for determining the effective tax rate.
Another new issue raised by GLoBE is the treatment of deferred taxes. For example, accelerated
depreciation may lead to large current depreciation deductions that will reduce the effective tax
rate currently but raise it in the future. The GLoBE rules allow taxes to be increased in the current
year to account for the timing with the increase recovered over time (lowering the effective tax
rate). This attribute is another one that may affect mergers or divisions given an expected decline
in the effective tax rate in the future when merging with a firm that has deferred tax liabilities.

Corporate Acquisitions and Divisions: Tax Issues

There is a similar type of treatment of deferred tax assets (savings that are expected in the
future).49
Some issues are not clear yet. For example, there is no indication that companies can choose a
338(g) election to treat an asset purchase as a stock purchase.
Potential Reforms
Concerns with mergers and acquisitions differ from those for divisive reorganizations (although
the two may be part of a single reorganization where part of a company is spun off before
merging with another company).
Mergers and Acquisitions
Tax-free mergers can be viewed as removing a barrier to mergers or as departing from the general
rule that gains are recognized when they are realized. The general justification for tax-favored
treatment under tax principles is that the business is continued by the same shareholders.
Nevertheless, stock received by shareholders in an exchange reflects a different investment from
the previous shares. This effect is especially pronounced for shareholders of a small company
acquired by a large company.
Aside from tax principles, perhaps the more important issue is the effect of mergers on market
power and anticompetitive behavior. The mechanism currently used to address this issue is
antitrust laws. At least some view these laws and their execution as too narrow.50 Eliminating or
reducing the tax benefits for mergers can be beneficial for society if mergers primarily lead to
market power rather than efficiency gains. Tax-free mergers could be denied altogether or a
higher share of stock compensation could be required to qualify for tax-free treatment.
Another consideration for tax policy is tax provisions that lead to mergers that would otherwise
not occur. Traditionally, this issue has focused on acquiring firms with net operating losses, which
is why the use of the losses is restricted to a measure of profit rate to the assets of the target.
However, the combined firm can gain a benefit if the gain from an asset acquisition is offset by
net operating losses, and the basis is increased to market value, increasing depreciation
deductions and reducing future capital gain.
As noted earlier, in recent years, policymakers have given special attention to inversions, where a
U.S. firm shifts its headquarters abroad in order to benefit from lower tax rates in foreign
jurisdictions and facilitate profit shifting. H.R. 884 (Doggett) and S. 357 (Whitehouse) would
treat firms where the former U.S. shareholders control more than 50% of the firm as U.S.
corporations. This treatment does not directly address the tax-free reorganization rules but does
further reduce the tax incentive for international mergers.
Special issues also arise with the use of debt financing for asset acquisitions, since the assets of
the target can also be used as security for the loan. Provisions in the tax code (Section 279) limit
the deductions for highly leveraged acquisitions.

Corporate Acquisitions and Divisions: Tax Issues

Divisions
Divisions do not raise the market concentration issues associated with acquisitions, and an
argument can be made that they are beneficial, leading to more efficient production. Most of the
concern with tax-free divisions is whether they are being used for their purpose, which is to
continue the historical business with historical shareholders, and whether they are being used to
distribute earnings in tax-preferred fashion. This section surveys some potential reforms to
tighten requirements for tax-free divisions that have been proposed in legislation and in law
review articles. While some of these reforms are suggested as regulations, they could also be
enacted into law.
Transactions with Debt
In the earlier versions of H.R. 5376 in the 117th Congress, which passed the House as the Build
Back Better Act, a provision would have tightened the rules regarding recognition of gain to the
parent (distributing) corporation. Under current law, the distributing corporation recognizes gain
on the amount of distributing corporation debt assumed by the subsidiary in excess of the basis of
property transferred and on boot in excess of basis reduced by debt assumed. The distributing
corporation can receive tax free any newly issued securities of the subsidiary and use them to pay
the distributing company creditors. This provision would reduce the basis by any securities of the
controlled corporation received, so that gain will be recognized to the extent the sum of boot,
assumed liabilities, and controlled corporation securities exceeds the basis of assets transferred.
This change would result in equal treatment of all forms of receipt other than the controlled
corporation’s stock, but would make it more difficult to reallocate debt between the parent and
subsidiary.51

In a law review article, Schler proposes that distribution of stock to creditors would be taxable to
the parent.52 Boot in excess of basis less assumed liabilities would be taxable to the parent if
distributed to creditors.
Both these proposals would increase the firm-level tax in certain transactions involving debt.
Business Purpose
Whether a division meets a business purpose can be unclear. Schler proposes two alternatives to
simplify dealing with the business purpose test, one to tighten the business purpose test so that
there has to be a fundamental and objective purpose, such as avoiding regulatory problems with
an acquisition or when competitors of a parent do not want to deal with a subsidiary when related
to the parent.53 It would eliminate reasons such as different shareholders wanting to focus on
different businesses. He notes that this could be justified in light of General Utilities repeal, but
also states that it is not clear such a proposal would be consistent with congressional intent. A
second alternative would be to expand it to include enhancing shareholder value, the same as in
other reorganizations other than to facilitate shareholder sales. Either alternative would simplify
the test, but the first alternative would be more restrictive. Schler prefers the second alternative, in

part because he thinks the first may be too restrictive. It might be difficult to put this change into
legislative language to codify the rule.
Continuity of Interest
Wells argues that the various responses to limiting the ability of Section 355 divisions to
circumvent General Utilities involve inconsistent standards across provisions regarding
continuity of interest and are applied under the regulations with subjective factors considered. He
suggests a bright-line objective test that includes a five-year testing period before the distribution
and a two-year testing period after it. He suggests use of the rules in Section 382, which limit the
carryover of certain tax attributes (such as net operating losses and unused credits) when an
ownership change has occurred. Under this provision, ownership change occurs when 5% of
shareholders together gain more than 50% of the corporation through acquisition in the testing
period. His basic view is that Section 355 should not allow nonrecognition to divisions that allow
assets to be transferred to a new shareholder group, and that the present rules do not achieve that
purpose.
Yin suggests that Treasury regulations have undermined much of the intent of Section 355 and
suggests providing a fixed period of time during which a significant change in ownership would
disallow tax-free treatment, which cannot be rebutted.54 He also indicates that a change in
ownership should not reflect changes as the result of the division itself or portfolio trading
(selling stock by shareholders who own less than a small percentage of the shares), but that
liquidation of a corporate component of the division should count as an asset change.
Beller suggests a general section that would disallow tax-free treatment (of both the corporation
and the shareholders) if control changed by 50% or more in a period before and after the spin-off
(e.g., two years before and two years after). This rule could replace Sections 355(d) (disqualified
distributions) and 355(e) (Morris Trust Rules). This treatment also might be limited to
disallowing tax-free treatment at the corporate level, as is the current case for these sections.
(Note, however, that current Section 355(d) has a more restrictive rule for five years before the
distribution. Thus, it is not clear that this provision is more restrictive.)
Control
Both Schler and Beller would replace the current control test with a requirement of 80% of stock
by vote and value.55
Treatment of Distributions
Wells would treat as a dividend a distribution when the other corporation is excessively
leveraged, which he suggests would occur when the other corporation has a debt-to-equity ratio
that is 120% of the average ratio before the division.56 This leveraging change pushes more of the
assets into the corporation whose stock is being distributed.

Corporate Acquisitions and Divisions: Tax Issues

Active Business Requirement and the Device Test
A common theme in proposals (outside of the provision in the Build Back Better Act) is the
limited requirement for the share of active business assets in total assets. There is currently no
limit, although some standards are in the proposed 2016 regulations. Wells suggests requiring
both the distributing and controlled corporation to have more than 50% of assets in historically
active business assets.57 He argues that the purpose of Section 355 is to separate a historical
business between historical shareholders, and without this standard the division only serves to
distribute assets out of corporate solution. While he proposes this standard as part of the
regulations, it could be enacted in statute.
Beller has a similar active business test proposal to require 50% of assets in historical assets.58 He
also suggests that consideration should be given to treating as boot a distribution of subsidiary
stock attributable to nonbusiness assets. If a 50% test is adopted, Section 355(g) would need to be
amended to conform, by reducing the two-thirds of assets rule. If the 50% active business asset
rule applies, and either the distributing firm or subsidiary has a certain amount (e.g., 25%) of
assets in nonbusiness assets, this amount would be evidence of a device. He also proposes that
both the distributing and controlled corporations should be required to continue in the same
business for two years, unless the taxpayer can demonstrate the change was not part of the
divisive reorganization plan.
Schler also suggests a higher active business percentage of 50%, but would set it as a requirement
for the combined entities.59 He also suggests that business assets acquired under the business
expansion rule within five years should be treated as evidence of a device under the device
restriction rule. Distributions by the parent would be taxable if assets satisfying the active 50%
business requirement acquired within the past five years were some (to be determined, perhaps
20% or 25%) share of the total and the facts and circumstances indicate that tax-free treatment
would be inconsistent with General Utilities repeal or the 50% business test.
Schler has a number of proposed revisions to the device test, although he argues that the device
test should be retained. One of the features indicating evidence of a device is the existence of a
secondary business that serves other businesses and could be sold without affecting the main
businesses. Schler argues that this feature should be eliminated, as it is no different from other
business components. He also indicates that a rule that a public corporation should show that
there is no intention of 5% of shareholders to sell as evidence against a device could be revised.
He indicates that shareholders without management influence, such as mutual funds, should not
be included in this test. Schler also argues that assets acquired within the five-year testing period
in the same trade or business, which are currently treated as five-year assets under the expansion
of business doctrine, should be excluded from the five-year test.
