Small Business Expensing Allowance: Current Status,
Legislative Proposals, and Economic Effects
Summary
Under current federal tax law, business taxpayers may deduct (or expense) up
to $250,000 of the total cost of certain assets placed in service in 2008, within certain
limits. Without such an option, firms would have to recover the cost over a longer
period, using current depreciation schedules. The rules governing the use of the
allowance limit most of its benefits to relatively small firms.
This report focuses on the economic effects of the small business expensing
allowance. It begins by explaining how the allowance works; moves on to
summarize its legislative history and describe legislation in the 110th Congress to
modify the allowance; and concludes with a discussion of the allowance’s
implications for economic efficiency, the distributional effects of the federal income
tax, and tax administration. The report will be updated to reflect significant
legislative activity.
There has been substantial bipartisan support for enhancing the expensing
allowance in the 110th Congress. In May 2007, the House and Senate passed a bill
(H.R. 2206, P.L. 110-28) that included an increase in the expensing allowance to
$125,000 and the phaseout threshold for the allowance to $500,000 in 2007, indexing
both amounts for inflation from 2008 to 2010, and extending through 2008 the
enhanced expensing allowance for qualified property used in the Gulf Opportunity
Zone.
Then in February 2008, the House and Senate approved an economic stimulus
bill (H.R. 5140, P.L. 110-185) that boosted the allowance to $250,000 and the
phaseout threshold to $800,00 in 2008 only. Under current law, the allowance will
revert to $125,000 and the threshold to $500,000 in 2009 and 2010.
Several other bills would permanently enhance the allowance or extend its
reach, including S. 3119, S. 3162, and H.R. 6611. Companion bills in the House
(H.R. 6587) and Senate (S. 3322) would greatly increase the expensing allowance
and phaseout threshold for qualified assets placed in service in 2008 in areas of the
Midwest that were declared presidential disaster areas in the summer of 2008.
The expensing allowance has a seemingly minor effect on the composition and
allocation of business investment, the distribution of the federal tax burden among
income groups, and the cost of tax compliance for smaller firms. These effects
loosely correspond to the three traditional criteria for evaluating tax policy:
efficiency, equity, and simplicity. While the allowance has the potential to spur
increased small business investment by reducing the user cost of capital for eligible
assets and increasing the cash flow of firms that claim the allowance, it can impair
economic efficiency by encouraging higher investment in activities yielding relatively
low pre-tax returns. At the same time, the allowance appears to have no measurable
impact on the distribution of the federal tax burden among income groups. In
addition, it has the advantage of lessening the burden of tax compliance by
simplifying tax accounting for firms claiming it.

Small Business Expensing Allowance:
Current Status, Legislative Proposals,
and Economic Effects
Provided certain conditions are met, firms may expense (or deduct) up to
$250,000 of the cost of qualified assets they place in service in 2008. Some refer to
this option for capital cost recovery as the small business expensing allowance
because the rules governing its use restrict the option’s benefits mainly to firms that
are relatively small in asset, employment, or revenue size. Firms unable to claim the
expensing allowance can recover the cost of the same assets over longer periods
through claiming allowable depreciation deductions. The expensing allowance
represents a significant tax subsidy for small business investment because it can
reduce the marginal effective rate at which the returns to investment in qualified
assets are taxed.
This report examines the current status of the small business expensing
allowance, its main economic effects, and initiatives in Congress to modify it. The
report begins by explaining the allowance’s design and summarizing its legislative
history. It then discusses proposals in the 110th Congress to alter the current
allowance. The report concludes with an assessment of the allowance’s implications
for economic efficiency, equity, and tax administration.
Current Expensing Allowance
Under section 179 of the Internal Revenue Code (IRC), business taxpayers have
the option of deducting (or expensing) the full cost of qualified assets (or property)
they purchase in the year when the assets are placed in service, within certain limits.
Business taxpayers that are unable or unwilling to take advantage of this option for
capital cost recovery may recover this cost over longer periods by claiming allowable
depreciation deductions.
In 2008, the maximum expensing allowance is $250,000 for firms operating
outside so-called enterprise and empowerment zones (EZs), renewal communities
(RCs), and the areas affected the most by Hurricane Katrina (also known as the Gulf
Opportunity Zone, or GOZ).1 (For the sake of clarity, this allowance is henceforth
referred to as the regular allowance.) For firms operating within all the special areas
except the GOZ, the maximum allowance in 2008 is $285,000. For firms located in

The allowance is indexed for inflation in 2004 through 2010. In 2003, it was $100,000;
in 2004, $102,000; in 2005, $105,000; in 2006, $108,000; and in 2007, $125,000.
CRS-2
the GOZ, the maximum allowance in 2008 for qualified assets purchased on or after
August 28, 2005, and placed in service by December 31, 2008, is $350,000.
The regular allowance is scheduled to fall back to $125,000 in 2009 and 2010,
with each amount indexed for inflation. Assuming no change in current law, it is
scheduled to revert to $25,000 (its level before the enactment of the Jobs and Growth
Tax Relief Reconciliation Act of 2003, or JGTRRA) in 2011 and each year thereafter
for firms operating outside the special areas. In the same period, the allowance will
fall to $60,000 for firms operating in all the special areas except the GOZ, and to
$125,000 for firms operating in the GOZ.
Business taxpayers choose the expensing option by following rules set forth by
the Internal Revenue Service (IRS). Under IRS Regulation 1.179-5, these taxpayers
may make or revoke an election under IRC Section 179 for property placed in service
through 2010 without the consent of the IRS Commissioner by submitting an
amended tax return for the tax year in question. For tax years beginning in 2011, an
expensing election may be revoked only with the consent of the Commissioner.
Firms in all lines of business may claim the regular expensing allowance. The
same is true of the enhanced expensing allowance available to firms operating in the
special areas, with certain exceptions. More specifically, the allowance does not
apply to qualified property placed in service in the following establishments located
in EZs, RCs, and the newly created GOZ: private or commercial golf courses,
country clubs, massage parlors, hot-tub and suntan facilities, stores whose principal
business is the sale of alcoholic beverages, racetracks, and facilities used for
gambling.
Qualified property is defined as certain new and used depreciable assets — as
specified in IRC Section 1245(a)(3) — acquired for use in the active conduct of a
trade or business. With a few notable exceptions, this property consists of business
machines and equipment used in connection with manufacturing or production,
extraction, transportation, communications, electricity, gas, water, and sewage
disposal. Transportation equipment with an unloaded gross weight of more than
6,000 pounds may be expensed, but not heating and air conditioning units. In
addition, packaged computer software acquired for business use may be expensed
through 2009. Most buildings and their structural components do not qualify for the
regular allowance, although research and bulk storage facilities do qualify. In the
case of firms located in the GOZ, however, certain residential and commercial
properties do qualify.
The maximum amount of qualified property that may be expensed in a single
tax year under IRC Section 179 is subject to two limitations: a dollar limitation and
an income limitation.
Under the dollar limitation, the regular expensing allowance is reduced by the
amount by which the total cost of qualified property placed in service during the year
exceeds a phase-out threshold. But in the case of firms operating in EZs, RCs, and
the NYLZ, the expensing allowance is reduced by half of the amount by which the
cost of qualified property placed in service in a tax year exceeds the threshold. The
threshold is set at $800,000 in 2008 for all firms except those operating in the GOZ,
CRS-3
which face a threshold of $1,400,000.2 As a result of this dollar limitation, a business
taxpayer operating outside the GOZ and the other special areas may expense none of
the cost of qualified property it places in service in 2008 when the total cost of that
property equals or exceeds $1,050,000. For example, if such a firm were to place in
service qualified property whose total cost in 2008 were to come to $750,000, it
would be allowed to deduct the entire amount under IRC Section 179.
The threshold for the regular allowance is scheduled to fall back to $500,000 in
2009 and 2010; it is indexed for inflation in both years. Assuming no change in
current law, the threshold is scheduled to revert to its pre-JGTRRA level of $200,000
in 2011 and each year thereafter.
Under the income limitation, the expensing allowance a firm claims cannot
exceed the taxable income (including wages and salaries) it earns from the active
conduct of the trade or business in which the qualified assets are used. For example,
if the firm in the above example were to have taxable income in 2008 of $25,000 in
the business in which the qualified property is used, it would be able to claim a
maximum expensing allowance of $25,000, instead of the $750,000 it otherwise
would be entitled to claim. Although business taxpayers may not carry forward any
expensing allowance lost because of the dollar limitation, they may carry forward an
allowance denied because of the income limitation.
In addition to the expensing allowance, business taxpayers were able to claim
a temporary 30% first-year depreciation deduction under the Job Creation and
Worker Assistance Act of 2002 (P.L. 107-147), or a temporary 50% first-year
depreciation deduction under Jobs and Growth Tax Relief Reconciliation Act of 2003
(JGTRRA, P.L. 108-26). Both deductions applied to new (but not used) property
depreciable under the modified accelerated cost recovery system (MACRS) and
having a recovery period of less than 20 years. Qualified property acquired between
September 11, 2001, and December 31, 2004, and placed in service before January
1, 2005, was eligible for the 30% depreciation deduction. The 50% deduction was
available for qualified property bought between May 6, 2003, and January 1, 2005,
and placed in service by January 1, 2006. Business taxpayers were permitted to
claim either the 30% or the 50% deduction, but not both.
The Economic Stimulus Act of 2008 (P.L. 110-185) reinstated the temporary
50% first-year depreciation deduction that expired at the end of 2006. It applies to
the same set of depreciable assets targeted by the earlier deduction. To benefit from
the partial expensing allowance, a firm must buy qualified assets and place them in
service between January 1, 2008, and December 31, 2008; an exception is made for
certain assets (e.g., aircraft) with relatively long production periods. The allowance
expires at the end of 2008.
For property eligible for both the expensing and special depreciation allowances,
a firm is required to recover the property’s cost in a prescribed order. The expensing

Like the maximum expensing allowance, the phase-out threshold is indexed for inflation
in 2004 through 2010. In 2003, the threshold was $400,000; in 2004, $410,000; in 2005,
$420,000; in 2006, $430,000; and in 2007, $500,000.

allowance must be claimed first, reducing the taxpayer’s basis in the property by the
amount of the allowance. Then the taxpayer may apply the 50% first-year
depreciation allowance to any remaining basis, further reducing the taxpayer’s basis
in the property. Finally, the taxpayer may claim a depreciation allowance under the
MACRS on any remaining basis, using the most advantageous depreciation method,
which is the double declining balance method.
Legislative History of the Expensing Allowance
The expensing allowance under IRC Section 179 originated as a special firstyear depreciation allowance included in the Small Business Tax Revision Act of
1958 (P.L. 85-866). It was intended to reduce the tax burden on small business
owners, stimulate small business investment, and simplify tax accounting for smaller
firms. The deduction was limited to $2,000 ($4,000 in the case of a married couple
filing a joint return) of the cost of new and used business machines and equipment
with a depreciation life of six or more years.
This allowance remained in force until the passage of the Economic Recovery
Tax Act of 1981 (ERTA, P.L. 97-34). ERTA replaced the special deduction with a
maximum expensing allowance of $5,000 and specified a timetable for gradually
increasing the allowance to $10,000 by 1986. Despite these changes, few firms took
advantage of the new allowance. Some analysts ascribed such a tepid response to the
limitations on the use of the investment tax credit also established by ERTA. A
business taxpayer claiming the credit for the purchase of an asset that also was
eligible for the expensing allowance could claim the credit only for the portion of the
asset’s cost that was not expensed. For many firms, the potential tax savings from
claiming the credit evidently outweighed the potential tax savings from claiming both
the credit and the allowance.
Faced with large and growing federal budget deficits in the early 1980s,
Congress passed the Deficit Reduction Act of 1984 (P.L. 98-369), which, among
other things, postponed from 1986 to 1990 the scheduled increase in the maximum
expensing allowance to $10,000. Claims for the allowance rose markedly following
the repeal of the investment tax credit by the Tax Reform Act of 1986.
The maximum allowance reached $10,000 in 1990, as scheduled, and remained
at that amount until the passage of the Omnibus Budget Reconciliation Act of 1993
(OBRA93, P.L. 103-66). OBRA93 retroactively raised the maximum allowance to
$17,500 (as of January 1, 1993) and added a variety of tax benefits for special areas
known as enterprise zones and empowerment zones (EZs). One of these benefits was
an expensing allowance for qualified assets placed in service in a special area that
was $20,000 above the regular allowance, with a phase-out threshold twice as large
as the phase-out threshold for the regular allowance. To be designated as an EZ, an
area had to satisfy a variety of eligibility criteria relating to population, poverty rate,
and geographic size.
With the passage of the Small Business Job Protection Act of 1996 (P.L. 104188), the regular allowance embarked on another upward path. The act raised the
CRS-5
maximum allowance to $18,000 in 1997, $18,500 in 1998, $19,000 in 1999, $20,000
in 2000, $24,000 in 2001 and 2002, and $25,000 in 2003 and thereafter.
Through the Community Renewal Tax Relief Act of 2000 (P.L. 106-544),
Congress expanded the list of special areas to include so-called “renewal
communities” (RCs) and granted them the same tax benefits available to EZs,
including an enhanced expensing allowance. The act also increased the maximum
allowance for qualified assets placed in service in a tax year in the special areas
(including RCs) to $35,000 above the regular allowance.
In response to the terrorist attacks of September 11, 2001, Congress established
a variety of tax benefits through the Job Creation and Worker Assistance Act of 2002
(P.L. 107-147) to encourage new business investment in the section of lower
Manhattan in New York City that bore the brunt of the attacks on the World Trade
Center. The act designated this area the New York “Liberty Zone.” Among the tax
benefits offered to firms located in the zone was the same enhanced expensing
allowance available for qualified investments in EZs and RCs.
The regular allowance remained on the upward path laid down by the Small
Business Jobs Protection Act until the adoption of JGTRRA. Under JGTRRA, the
maximum regular allowance rose four-fold to $100,000 in May 2003 and was to stay
at that amount in 2004 and 2005, before returning to $25,000 in 2006 and thereafter.
JGTRRA also raised the phase-out threshold to $400,000 over the same period,
indexed both the regular allowance and the threshold for inflation in 2004 and 2005,
and added off-the-shelf software for business use to the list of depreciable assets
eligible for expensing in 2003 through 2005.
Under the American Jobs Creation Act of 2004 (AJCA, P.L. 108-357), the
changes in the allowance made by JGTRRA were extended another two years, or
through 2007.
In an effort to spur economic recovery in the areas of Louisiana, Mississippi,
and Alabama devastated by Hurricane Katrina, Congress passed the Gulf Opportunity
Zone Act of 2005 (P.L. 109-135). Among other things, the act designated these areas
as the Gulf Opportunity Zone (GOZ), and offered a variety of tax incentives for new
business investment in the GOA, including an enhanced expensing allowance for
qualified assets purchased on or after August 28, 2005, and placed in service by
December 31, 2007. The expensing allowance can be as much as $100,000 above
the regular allowance. In addition, it begins to phase out when the total cost of
qualified assets placed in service by a business taxpayer in a tax year exceeds a
threshold that is $600,000 above the phase-out threshold for the regular allowance.
Finally, the range of assets eligible for the enhanced allowance is greater than that for
the regular allowance.
The Tax Increase Prevention and Reconciliation Act of 2005 (P.L. 109-222)
extended the changes in the allowance made by JGTRRA through 2009.
Finally, in passing the U.S. Troop Readiness, Veterans’ Care, Katrina Recovery,
and Iraq Appropriations Act, 2007 (P.L. 110-28), Congress extended the changes in
the allowance made by JGTRRA through 2010, raised the maximum allowance to
CRS-6
$125,000 and the phaseout threshold to $500,000 in 2007 to 2010, and indexed both
amounts for inflation from 2008 through 2010. The act also extended through 2008
the enhanced expensing allowance for qualified assets placed in service in the GOZ.
Congress boosted the allowance to $250,000 and the phaseout threshold to
$800,000 in 2008 only by passing the Economic Stimulus Act of 2008 (P.L. 110185). Those amounts revert back to $125,000 and $500,000 in 2009 and 2010,
respectively.
Legislative Initiatives in the 110th Congress
Legislative activity in recent Congresses demonstrated that there was broad
bipartisan support for enhancing the expensing allowance, as a means of both
spurring increased business investment and funneling aid to small business owners.
By all accounts, this support remains as robust as ever in the current Congress.
Bills to extend the enhancements in the regular allowance made by JGTRRA and to
enhance temporarily the current allowance as a way to spur faster domestic economic
growth have been enacted. Other bills to further enhance the allowance on a
permanent basis have been introduced.
Between late March and mid-May 2007, the House and Senate passed two bills
(H.R. 1591 and H.R. 2206) that included further enhancements of the expensing
allowance. Specifically, each measure would have raised the maximum allowance
to $125,000 and the phaseout threshold to $500,000 from 2007 through 2010,
indexed both amounts for inflation in 2008 to 2010, extended through 2010 all other
features of the allowance that are set to expire in 2009, and extended through 2008
the enhanced expensing allowance under IRC Section 1400(N) for qualified property
placed in service in the GOZ. President Bush vetoed H.R. 1591 on May 1, 2007, but
he signed H.R. 2206 (P.L. 110-28) on May 25.
Faced with mounting evidence of a pronounced slowdown in domestic
economic activity, Congress showed a renewed interest in using the allowance as a
tool for stimulating faster economic growth in early 2008. On January 24, the leaders
of the House and the Bush Administration announced they had reached an agreement
on an economic stimulus package that included an increase in the allowance to
$250,000 and in the threshold to $800,000 in 2008 only. Five days later, the House
passed a measure (H.R. 5140) incorporating the terms of that agreement. The Senate
did likewise on February 7. President Bush signed the legislation on February 13.
Under the law, the allowance and threshold will revert to preexisting law in 2009 and
beyond.
There are some indications that this interest has not abated a good deal in the
months since the enactment of the stimulus legislation. Several bills to enhance
permanently the allowance and its phaseout threshold have been introduced in recent
months. S. 3119 would permanently raise the maximum allowance to $128,000 and
the phaseout threshold to $500,000 in 2009 and beyond and adjust both amounts for
inflation. S. 3162 would permanently set the maximum allowance at $125,000 and
CRS-7
the phaseout threshold at $500,000 in 2009 and thereafter, adjust both amounts for
inflation, and make purchases of off-the-shelf computer software for business use
permanently eligible for the expensing allowance; and H.R. 6611 would permanently
increase allowance to $250,000 and the phaseout threshold to $800,000 and adjust
both for inflation, starting in 2009.
In addition, companion bills in the House (H.R. 6587) and Senate (S. 3322)
would offer temporary tax relief for taxpayers located in areas of certain Midwestern
states that were declared presidential disaster areas as a result of severe storms,
flooding, and tornados that occurred early in the summer of 2008. Each bill contains
a provision that would raise the expensing allowance to $350,000 and the phaseout
threshold to $1.4 million for qualified assets placed in service in 2008 in any of the
disaster areas. To qualify for this treatment, an asset would have to be eligible for
the Section 179 expensing allowance and meet the definition of qualified Gulf
Opportunity Zone property under IRC Section 1400N(d)(2).
The Bush Administration has signaled that it would back a further enhancement
of the expensing allowance. Its budget request for FY2009 includes a permanent
increase in the maximum allowance to $200,000 and the phase-out threshold
allowance to $800,000 and a permanent indexation of these amounts for inflation,
starting in 2009.3 According to the Treasury Department, these changes in the
allowance would result in an estimated revenue loss of $7.6 billion from FY2009 to
FY2018.4
Economic Effects of the Expensing Allowance
To many lawmakers, the expensing allowance represents a desirable policy tool
for aiding small business owners and stimulating the economy at the same time. To
many small business owners, the allowance represents a desirable tax benefit. But
to most public finance economists, the allowance has economic effects that extend
beyond its implications for the tax burden of small business owners. In their view,
the allowance may affect the allocation of investment capital within the private
sector, the distribution of the federal tax burden among major income groups, and the
cost of tax compliance for smaller firms. These effects loosely correspond to the
three traditional criteria for evaluating tax policy: efficiency, equity, and simplicity.
Each is discussed below.
Efficiency Effects
Efficiency lies at the heart of economic theory and analysis. It refers to the
allocation of resources in an economy and how it shapes the welfare of consumers
and producers. When such an allocation generates the greatest possible economic
surplus — defined as the total value to buyers of the goods and services they

Year 2009 Revenue Proposals (Washington: Feb. 2008), pp. 17-18.

CRS-8
consume minus the total cost to sellers of providing these goods and services — the
allocation is said to be efficient. But when an allocation is less than efficient, some
of the possible gains from exchange among buyers and sellers are not being realized.
For example, an allocation is deemed inefficient when most suppliers of a good fail
to produce it at the lowest marginal cost permitted by existing technologies. In this
case, a shift in supply from relatively high-cost producers to relatively low-cost
producers, driven perhaps by an unleashing of market forces, would lower the total
economic cost of providing the good, thereby raising the overall economic surplus.
One important policy issue raised by the small business expensing allowance
concerns its effect on the allocation of resources in general and the allocation of
investment capital within the private sector in particular. In theory, all taxes except
lump-sum taxes lead to inefficient outcomes because they influence the decisions of
consumers and producers in ways that leave one group or the other — or both —
worse off. Non-lump-sum taxes have this effect because they inevitably distort the
incentives facing individual and business taxpayers, leading them to allocate
resources according to the effects of the taxes on the costs and benefits of the goods
and services they buy and sell rather than their actual costs and benefits. Such a
distortion entails what economists call a deadweight loss, which is a condition where
the amount of revenue raised by a tax is less than the loss of economic welfare it
engenders.
The expensing allowance has the potential to affect the allocation of resources
in the U.S. economy by encouraging firms able to claim it to invest in assets that
qualify for the allowance, possibly at the expense of other more productive assets.
There are two channels through which the allowance can have such an effect. The
more important of the two is thought to be a reduction in the user cost of capital for
investment in qualified assets relative to all other assets. A second channel is a
temporary increase in the cash flow or internal funds available to firms that purchase
qualified assets. Restraining the allowance’s influence over the allocation of
resources is its phase-out threshold, which effectively confines the benefits of the
allowance to firms that are relatively small in asset size.5
As one would expect, the user cost of capital plays a major role in a firm’s
investment decisions. This cost encompasses both the opportunity cost of an
investment and the direct costs of that investment, such as depreciation, the cost of
the asset, and income taxes. In effect, the user cost of capital determines the after-tax
rate of return an investment must earn in order to be profitable — and thus worth
undertaking. In general, the higher the user cost of capital, the fewer profitable
projects a firm can undertake, and the lower its desired capital stock. When a change
in tax policy decreases the user cost of capital, many firms can be expected to
respond by increasing the amount of capital they wish to own, boosting overall
business investment in the short run.

According to unpublished IRS estimates, a total of $55.161 billion in assets eligible for the
IRC Section 179 expensing allowance were placed in service in 2003. Firms with assets of
$10 billion or less accounted for 49% of this investment, whereas firms with assets of $100
billion or more accounted for 16%.
CRS-9
How does expensing affect the user cost of capital? Expensing is the most
accelerated form of depreciation: under expensing, the entire cost of an asset is
written off in its first year of use, regardless of the asset’s actual or useful life.
Allowing a firm to expense its acquisition of an asset is equivalent to the U.S.
Treasury providing the firm (or its owners) with a tax rebate equal to the firm’s
marginal tax rate multiplied by the cost of the asset. Accelerated depreciation —
along with other investment tax subsidies such as an investment tax credit — reduces
the user cost of capital by lowering the pre-tax rate of return on investment a firm
must earn in order to realize a desired after-tax rate of return.6 Expensing yields the
largest possible reduction in the user cost of capital from accelerated depreciation.
This reduction can be considerable.7
How beneficial is expensing? One way to illustrate the tax benefit from
expensing is to show how it affects the marginal effective tax rate on the returns to
investment in an asset that is expensed for tax purposes. Expensing has the effect of
taxing the stream of income earned by an asset over its lifetime at a marginal
effective rate of zero.8 This is because expensing reduces the after-tax returns and
costs for eligible investments by the same factor: an investor’s marginal tax rate.
For example, if the income received by a small business owner is taxed at a rate of
35% and a depreciable asset he or she buys is expensed, then the federal government
effectively becomes a partner in the investment with an interest of 35%. Through the
tax code, the federal government assumes 35% of the cost of the asset by allowing
its entire cost to be deducted in the first year of the asset’s use, and it receives 35%
of the income earned by the investment in subsequent years. Conversely, expensing
6
The user cost of capital is the real rate of return an investment project must earn to be
profitable. In theory, a firm will undertake an investment provided the after-tax rate of
return exceeds or at least equals the user cost of capital. Rosen has expressed this cost in
terms of a simple equation. Let C stand for the user cost of capital, a for the purchase price
of an asset, r for the after-tax rate of return, d for the economic rate of depreciation, t for the
corporate tax rate, z for the present value of depreciation deductions flowing from a $1
investment, and k for the investment tax credit rate. Then C = a x [(r +d) x (1-(t x z)-k)]/(1t). Under expensing, z is equal to one. By plugging assumed values for each variable into
the equation, one sees that C increases as z gets smaller. Thus, of all possible methods of
depreciation, expensing yields the lowest user cost of capital. For more details, see Harvey
S. Rosen, Public Finance, 6th ed (New York: McGraw-Hill/Irwin, 2002), pp. 407-409.

In a 1995 study, Douglas Holtz-Eakin compared the cost of capital for an investment under
two scenarios for cost recovery. In one, the corporation making the investment used
expensing to recover the cost of the investment; and in the other, the cost was recovered
under the schedules and methods permitted by the modified accelerated cost recovery
system. He further assumed that the interest rate was 9%, the inflation rate 3%, and the rate
of economic depreciation for the asset acquired through the investment 13.3%. Not only did
expensing substantially reduce the cost of capital, its benefit was proportional to the firm’s
marginal tax rate. Specifically, Holtz-Eakin found that at a tax rate of 15%, expensing
lowered the cost of capital by 11%; at a tax rate of 25%, the reduction was 19%; and at a tax
rate of 35%, the cost of capital was 28% lower. See Douglas Holtz-Eakin, “Should Small
Businesses Be Tax-Favored?” National Tax Journal, September 1995, p. 389.

allows the small business owner to receive 65% of the returns from the investment
but to bear only 65% of the cost. Such an outcome implies that for each dollar spent
on the asset, the owner earns the same rate of return after taxes as before taxes.9
Expensing could also support a sustained rise in business investment by
augmenting the cash flow of firms that rely heavily on internal funds or retained
earnings to finance the bulk of their investments and have positive net incomes.10
Expensing can increase a firm’s cash flow in the short run because it allows the firm
to deduct the full cost of qualified assets it purchases in the tax year when they are
placed into service. There are a variety of reasons why a firm’s investments could
hinge on its cash flow. One is that the firm’s owners or senior managers want to
limit their exposure to external debt and the risks it entails. Another reason is that
the firm has limited or no access to debt and equity markets, mainly because of a lack
of accurate information on its assets, strategies, or prospects for achieving relatively
high rates of return on equity. For a firm in such a position, the cost of internal funds
could be lower than the cost of external funds, in which case the firm and its owners
would be better off if the firm were to finance most of its investments out of retained
earnings.
What is unclear is how increases in cash flow in the aggregate affect overall
business investment. Some studies have found a significant positive correlation
between changes in a firm’s net worth (or supply of internal funds) and its investment
spending.11 What is more, this correlation was strongest for firms facing serious
obstacles to raising funds in debt and equity markets because of insufficient
information on the part of investors or lenders. Nevertheless, it would be a mistake
to interpret these findings as conclusive evidence that firms with relatively high cash
flows invest more than firms with relatively low or negative cash flows. After all,
a strong correlation between two variable factors does not prove the existence of a
cause-and-effect relationship between them. It may be the case that firms with
relatively high cash flows invest more, on average, than firms with relatively low
cash flows for reasons that have little or nothing to do with the relative cost of
internal and external funds. The link between cash flow and business investment is
complicated; further research is needed to clarify it.
Is there reason to believe that the expensing allowance has contributed to shifts
in the size and composition of the domestic capital stock in the 25 years the
allowance has existed in its present form? This question is difficult to answer
because there are no studies analyzing the impact of the allowance on capital
formation over time, and empirical evidence is incomplete. Given that the expensing

In the realm of business finance, the term “cash flow” can take on different meanings.
Here it denotes the difference between a firm’s revenue and its payments for all the factors
or inputs used to generate its output, including capital equipment.

CRS-11
allowance lowers the cost of capital and may boost cash flow for many firms able to
claim it, and that investment in many of the assets eligible for the allowance seems
somewhat sensitive to reductions in the cost of capital, one might be justified in
concluding that the allowance has caused domestic investment in those assets to be
greater than it otherwise would have been.12 Yet there are equally compelling
reasons to infer that much of this investment would have taken place without the
expensing allowance.13 Most economists would probably agree that investment in
assets eligible for the expensing allowance is likely to be driven more by business
expectations for future growth in sales, the nature of the capital goods themselves,
and conditions in debt and equity markets than by tax considerations.14 This view
finds some support in available data on use of the expensing allowance: although
22% of corporations filing federal tax returns claimed the allowance from 1999
through 2003, the total value of IRC Section 179 property placed in service was equal
to only 5% of domestic gross investment in equipment and computer software.15
When seen through the lens of conventional economic theory, the expensing
allowance acts like a drain on efficiency that may worsen the deadweight loss caused
by the federal tax code. Under the reasonable assumption that the amount of capital
in the economy is fixed in the short run, a tax subsidy like the allowance has the
potential to lure some capital away from highly profitable productive uses and into
tax-favored uses. Conventional economic theory holds that in an economy free of
significant market failures and dominated by competitive markets, a policy of neutral
or uniform taxation of capital income would minimize the efficiency losses brought
on by income taxation. The expensing allowance, however, subtly encourages
investment in specific assets by relatively small firms. Such a subsidy can interfere
with the flow of financial capital to its most profitable uses by making it possible for
business owners to earn higher after-tax rates of return on investment in assets
eligible for the allowance than on investment in other assets with higher expected
pre-tax rates of return.
In addition, the expensing allowance gives firms able to claim it an incentive to
restrain their growth. This unintended incentive stems from the rise in marginal
effective tax rates on the income earned by an asset eligible for the allowance in the
12
Two studies from the 1990s found that a 1% decline in the user cost of capital was
associated with a rise in business equipment spending of 0.25% to 0.66%. See CRS Report
RL31134, Using Business Tax Cuts to Stimulate the Economy, by Jane G. Gravelle, p. 4.
13
There is some anecdotal evidence to support this supposition. At a recent hearing held
by the House Small Business Subcommittee on Tax, Finance, and Exports, Leslie Shapiro
of the Padgett Business Services Foundation stated that expensing “may be an incentive in
making decisions to buy new equipment, but it’s not the dominant force.” His firm provides
tax and accounting services to over 15,000 small business owners. See Heidi Glenn, “Small
Business Subcommittee Weighs Bush’s Expensing Boost,” Tax Notes, April 7, 2003, p. 17.

allowance’s phase-out range ($500,000 to $625,000 in 2007).16 Douglas HoltzEakin, the former Director of the Congressional Budget Office, has labeled this
incentive effect a “tax on growth by small firms.”17
Equity Effects
Equity is another basic concept in economic analysis. It generally refers to the
distribution of income among the individuals or households in a geographic area.
In the context of income taxation, equity usually denotes the distribution of the
tax burden among taxpayers divided into income groups. Economists who analyze
the equity effects of income taxes tend to focus on two distinct kinds of equity:
horizontal equity and vertical equity. A tax system is said to be horizontally
equitable if it imposes similar burdens on individuals with similar incomes or
standards of living. And a tax system is said to be vertically equitable if the burdens
it imposes vary according to an individual’s or household’s ability to pay. The
principle of vertical equity provides the foundation for any progressive income tax
system. Under such a system, an individual’s total tax liability, measured as a
fraction of income, rises with income.
The current federal income tax system seems to lean more in the direction of
vertical equity than horizontal equity. Many individuals with similar incomes before
taxes end up being taxed at the same marginal rate. But because of various tax
preferences in the form of deductions, preferential rates, deferrals, exclusions,
exemptions, and credits enacted over many years, a significant share of individuals
with similar before-tax incomes also end up being taxed at significantly different
rates. At the same time, those with relatively high pre-tax incomes are generally
taxed at significantly higher rates than those with relatively low pre-tax incomes.
The expensing allowance constitutes a tax preference, albeit one targeted at
business investment in certain assets. How does it affect vertical and horizontal
equity?
To answer this question, it is necessary to consider the tax benefits associated
with the expensing allowance, who receives them, and how they affect the recipients’
federal income tax burdens. The main tax benefit generated by the allowance is a
reduction in the marginal effective tax rate on the income earned by assets eligible
for the allowance. How much of a reduction depends critically on the proportion of
the asset’s cost that is expensed. As was noted earlier, if the entire cost is expensed,
then the marginal effective rate falls to zero. Nevertheless, the allowance does not
16
Jane Gravelle of CRS has estimated that, with a corporate tax rate of 28% and a rate of
inflation of 3%, the marginal effective tax rate on the income earned by assets eligible for
the expensing allowance is 36% in the phase-out range for the allowance. By contrast,
under the same assumptions, the marginal effective tax rate on the income earned by
qualified assets is 0% for each dollar of investment in those assets up to $430,000.

CRS-13
change the actual marginal rates at which this income is taxed. This is because
accelerated depreciation does not, in theory, reduce the total amount of taxes
(measured in current dollars) that will be paid on an asset’s expected stream of
income over its useful life. Rather, accelerated depreciation simply changes the
timing of depreciation deductions in ways that substantially boost the present
discounted value of the tax savings from depreciation allowances.
Most of the assets eligible for the allowance are owned by smaller firms. As a
result, it would be reasonable to assume that most of the tax savings generated by the
allowance end up in the pockets of small business owners. But such an inference is
implausible, since the allowance does not alter the income tax rates facing small
business owners — and thus has no direct effect on the distribution of the federal
income tax burden among income groups. As the allowance leaves the distributional
effects of the income tax unchanged, it has no impact on vertical or horizontal equity.
Tax Administration
Yet another interesting policy question raised by the expensing allowance
concerns its impact on the cost of tax compliance for business taxpayers.
Most public finance economists would agree that a desirable income tax system
is one that imposes relatively low costs for administration and compliance. Research
has shown that the administrative cost of a tax system hinges on three factors: (1) the
records that must be kept in order to comply with tax laws, (2) the complexity of
those laws, and (3) the types of income subject to taxation.
Many public finance economists would also agree that the current federal
income tax system fails this crucial test. In their view, the costs of collecting income
taxes and enforcing compliance with the tax laws are needlessly high, and the
primary cause is the complexity of the federal tax code. Many small business owners
have long complained about the costly burdens imposed on them by the record
keeping and filings required by the federal income tax.
The expensing allowance addresses this concern by simplifying tax accounting
for firms able to claim it. Less time and paperwork are involved in writing off the
entire cost of a depreciable asset in its first year of use than in recovering that cost
over a longer period applying complicated depreciation schedules. At the same time,
the rules governing the use of the credit in and out of specially designated areas add
a layer of complexity to the administration of the allowance by the IRS.
Tax simplification has long been a key policy objective for most small business
owners, largely because of the relatively high costs they must bear in complying with
federal tax laws. These costs were examined in a 2001 study prepared for the Office
of Advocacy of the Small Business Administration. According to the study, the cost
per employee for tax compliance in 2000 was an estimated $665 for all firms, $1,202
for firms with fewer than 20 employees, $625 for firms with 20 to 499 employees,
and $562 for firms with 500 or more employees.18

Small Business Expensing Allowance
Summary
Under the American Recovery and Reinvestment Act of 2009 (ARRA, P.L. 111-5), business
taxpayers may expense (or deduct as a current expense) up to $250,000 of the total cost of certain
depreciable assets placed in service in 2009, within certain limits. One limit is a phaseout
threshold, which is set at $800,000 in 2009. The act also allows business taxpayers to claim a socalled bonus depreciation allowance in 2009 that is equal to 50% of the cost of qualified assets
placed in service that year. Firms unable to use either option for accelerated depreciation have to
write off that cost over a longer period, using current depreciation schedules. The rules governing
the use of the allowance confine most of its benefits to relatively small firms.
This report focuses on the economic effects of what is referred to as the small business expensing
allowance. It begins by explaining how the allowance works, then summarizes its legislative
history and describes legislation in the 111th Congress to modify the allowance, and concludes
with a discussion of the allowance’s implications for economic efficiency, equity, and tax
administration. The report will be updated as necessary.
There was strong bipartisan support for enhancing the expensing allowance in recent Congresses,
and there are some early signs that this support has not waned in the 111th Congress. Several bills
to extend the enhanced allowance that was in effect in 2008 through 2009 or 2010 have been
introduced, capped by H.R. 1, the American Recovery and Reinvestment Act of 2009. The
version of H.R. 1 signed by President Obama contains a provision that would allow firms to claim
the same enhanced expensing allowance in 2009 that was available in 2008. The act also extends
through 2009 the 50% bonus depreciation allowance that applied to the purchase of qualified
assets in 2008.
The expensing allowance appears to have a minor effect on the composition and allocation of
business investment, the distribution of the federal tax burden among income groups, and the cost
of tax compliance for smaller firms. These effects correspond to the three traditional criteria for
evaluating tax policy: efficiency, equity, and simplicity. While the allowance has the potential to
spur increased small business investment by reducing the user cost of capital and increasing the
cash flow of firms that use the allowance, it can also harm economic efficiency by encouraging
greater investment in activities with relatively low pre-tax rates of return. At the same time, the
allowance appears to have no measurable impact on the distribution of the federal tax burden
among income groups, but it simplifies tax accounting for firms claiming it.

Small Business Expensing Allowance
P
rovided certain conditions are met, firms may expense (or deduct as a current expense) up
to $250,000 of the total cost of qualified assets they purchase and place in service in 2009.
Some refer to this option for capital cost recovery as the small business expensing
allowance, as the rules governing its use confine the allowance’s benefits mainly to firms that are
relatively small in asset, employment, or revenue size. Generally, firms that cannot use the
expensing allowance may recover the cost of the same assets over longer periods by claiming
allowable depreciation deductions. The expensing allowance represents a significant tax subsidy
for small business investment, as it reduces the marginal effective rate at which the returns to
investment in qualified assets are taxed.
The 111th Congress has already passed a bill (H.R. 1, the American Recovery and Reinvestment
Act of 2009 or ARRA, P.L. 111-5) that extends through 2009 an enhanced version of the
allowance that was available in 2008. It is hoped that such an investment tax subsidy will spur
many small firms to spend more on new equipment in 2009 than they otherwise would.
This report examines the current status of the small business expensing allowance, initiatives in
the 111th Congress to modify it, and its main economic effects The report begins by describing the
allowance’s design and summarizing its legislative history. It then discusses proposals in the
current Congress to modify the current allowance. The report concludes with an assessment of the
allowance’s implications for economic efficiency, equity, and tax administration.
Current Expensing Allowance
Under section 179 of the Internal Revenue Code (IRC), firms in all lines of business have the
option of expensing the cost of qualified assets (or property) they acquire in the year when the
assets are placed in service, within certain limits. In general, business taxpayers that are unable or
unwilling to take advantage of the expensing allowance may recover this cost over longer periods
by using allowable depreciation deductions.
Maximum Expensing Allowance
The maximum expensing allowance is $250,000 for qualified assets placed in service in 2009 by
firms located outside so-called enterprise and empowerment zones (EZs), renewal communities
(RCs), and presidentially declared disaster areas (PDDAs). 1 (For the sake of clarity, this
allowance is henceforth referred to as the regular allowance.) For firms operating within all
special areas except PDDAs, the maximum allowance for qualified assets placed in service in
2009 is $285,000. For firms located in PDDAs, the maximum allowance for qualified assets
placed in service in 2009 is $350,000.
In 2010, the regular allowance is scheduled to drop to $125,000, before adjustment for inflation;
it will be $160,000 for firms located in special areas other than PDDAs, and $225,000 for PDDA
firms; both amounts are indexed for inflation. Assuming no change in current law, the regular
allowance is scheduled in 2011 and beyond to drop to $25,000, its amount before the enactment

The allowance is indexed for inflation in 2004 through 2010. In 2003, it was $100,000; in 2004, $102,000; in 2005,
$105,000; in 2006, $108,000; in 2007, $125,000; and in 2008, $250,000. The large increase in 2008 was temporary and
resulted from a provision in the Economic Stimulus Act of 2008.

of the Jobs and Growth Tax Relief Reconciliation Act of 2003 (JGTRRA), with no adjustment for
inflation. Beginning in 2011, the allowance will fall to $60,000 for firms operating in all special
areas except PDDAs.
Qualified Property
Qualified property is defined as certain new and used depreciable assets—as specified in IRC
Section 1245(a)(3)—acquired for use in the active conduct of a trade or business. With a few
exceptions, this property consists of business machines and equipment used in connection with
manufacturing or production, extraction, transportation, communications, electricity, gas, water,
and sewage disposal. Transportation equipment with an unloaded gross weight of more than
6,000 pounds (including heavy-duty sport utility vehicles) is considered qualified property, but
not heating and air conditioning units. In addition, the cost of packaged computer software
acquired for business use may be expensed through 2009. Most buildings and their structural
components do not qualify for the regular allowance, but research and bulk storage facilities do
qualify.
The expensing allowance does not apply to qualified property placed in service in the following
kinds of establishments located in EZs, RCs, and PDDAs: private or commercial golf courses,
country clubs, massage parlors, hot-tub and suntan facilities, stores whose principal business is
the sale of alcoholic beverages, racetracks, and facilities used for gambling.
Limitations on the Use of the Expensing Allowance
The maximum amount of qualified property that may be expensed in a single tax year under IRC
Section 179 is subject to two explicit limitations: a dollar limitation and an income limitation.
Under the dollar limitation, the regular expensing allowance is reduced, dollar for dollar, by the
amount by which the total cost of qualified property placed in service during the year exceeds a
phaseout threshold. For firms operating in EZs, RCs, and the NYLZ, the expensing allowance is
reduced by half of the amount by which the total cost of qualified property placed in service in a
tax year exceeds the threshold. The threshold is set at $800,000 in 2009 for all firms except those
operating in PDDAs, which face a threshold of $1,400,000.2 As a result, a business taxpayer
located outside the special areas may expense none of the cost of qualified property it places in
service in 2009 when the total cost equals or exceeds $1,050,000. This means, for example, that if
such a firm were to place in service in 2009 qualified property whose total cost came to $550,000,
it could deduct the entire amount under IRC Section 179.
The phaseout threshold for the regular allowance is scheduled to fall to $500,000 in 2010, with an
adjustment for inflation. Assuming no change in current law, the threshold is scheduled to revert
to its pre-JGTRRA level of $200,000 (with no indexation for inflation) in 2011 and beyond.
Under the income limitation, the expensing allowance a firm claims cannot exceed its taxable
income (including wages and salaries) from the active conduct of the trade or business in which

Like the maximum expensing allowance, the phase-out threshold is indexed for inflation in 2004 through 2010. In
2003, the threshold was $400,000; in 2004, $410,000; in 2005, $420,000; in 2006, $430,000; in 2007, $500,000; and in
2008, $800,000.

the qualified assets are employed. For example, if the firm in the above example were to have
taxable income in 2009 of $25,000 from the business in which the qualified property is used, it
would be able to claim an expensing allowance of no more than $25,000. While business
taxpayers are not allowed to carry forward any expensing allowance lost because of the dollar
limitation, they may carry forward indefinitely any allowance denied because of the income
limitation.
Business taxpayers can also expect to face a new restriction on their ability to take advantage of
the expensing option in 2011. Under Internal Revenue Service (IRS) Regulation 1.179-5,
taxpayers currently may make or revoke an election under IRC Section 179 for property placed in
service through 2010 without the consent of the IRS Commissioner by submitting an amended tax
return for the tax year in question. For tax years beginning in 2011, however, an expensing
election may be revoked only with the consent of the Commissioner.
Bonus Depreciation Allowance
In addition to the expensing allowance, business taxpayers were able to claim a temporary 30%
first-year depreciation deduction under the Job Creation and Worker Assistance Act of 2002 (P.L.
107-147), or a temporary 50% first-year depreciation deduction under Jobs and Growth Tax
Relief Reconciliation Act of 2003 (JGTRRA, P.L. 108-26). Both deductions were commonly
referred to as bonus depreciation allowances and operated as partial expensing allowances. They
applied to new (but not used) property eligible for depreciation under the modified accelerated
cost recovery system (MACRS) and having a depreciation life of less than 20 years. Qualified
property acquired between September 11, 2001 and December 31, 2004, and placed in service
before January 1, 2005, was eligible for the 30% depreciation deduction. The 50% deduction
applied to qualified property bought between May 6, 2003 and January 1, 2005, and placed in
service by January 1, 2006. Since there was an overlap of nearly 19 months between the two
options for accelerated depreciation, business taxpayers were allowed to claim only one of them.
The Economic Stimulus Act of 2008 (P.L. 110-185) reinstated the 50% first-year bonus
depreciation allowance that expired at the end of 2006. It applies to the same set of depreciable
assets targeted by the earlier deduction. To benefit from this allowance, a firm had to buy
qualified assets and place them in service between January 1, 2008, and December 31, 2008; an
exception was made for assets with relatively long production schedules, such as aircraft. The
allowance expired at the end of 2008.
As a result of the ARRA, the bonus depreciation allowance that was available in 2008 has been
extended through 2009.
For property that is eligible for both the expensing and special depreciation allowances, a firm is
required to write off the property’s cost in a prescribed order. The expensing allowance must be
taken first, an act that reduces a taxpayer’s basis in the property by the amount of the allowance.
Then the taxpayer may apply the 50% first-year bonus depreciation allowance to any remaining
basis, further reducing the taxpayer’s basis in the property. Finally, the taxpayer is allowed to
claim a depreciation allowance under the MACRS on any remaining basis, using the double
declining balance method. Firms using all three allowances realize a significant reduction in their
cost of capital for investment in qualified property, as will be discussed below in some detail.

Small Business Expensing Allowance
Legislative History of the Expensing Allowance
The expensing allowance under IRC Section 179 originated as a special first-year depreciation
allowance that was included in the Small Business Tax Revision Act of 1958 (P.L. 85-866). It was
intended to reduce the tax burden on small business owners, stimulate small business investment,
and simplify tax accounting for smaller firms. The deduction was limited to $2,000 (or $4,000 in
the case of a married couple filing a joint return) of the cost of new and used business machines
and equipment with a depreciation life of six or more years.
This allowance remained in effect until the passage of the Economic Recovery Tax Act of 1981
(ERTA, P.L. 97-34). ERTA replaced the special deduction with a maximum expensing allowance
of $5,000 and laid down a timetable for gradually increasing the allowance to $10,000 by 1986.
Despite these enhancements, few firms took advantage of the new allowance. Some analysts
ascribed the tepid response to the limitations on the use of the investment tax credit that was also
established by ERTA. A business taxpayer claiming the credit for the acquisition of an asset that
also was eligible for the expensing allowance could claim the credit only for the portion of the
cost that was not expensed; so the full credit could be used only if no expensing allowance was
claimed. For many firms, the tax savings from the credit only evidently outweighed the tax
savings from a combination of the credit and the allowance.
In a bid to counter the growing federal budget deficits of the early 1980s, Congress passed the
Deficit Reduction Act of 1984 (P.L. 98-369). One of its provisions postponed from 1986 to 1990
the scheduled increase in the maximum expensing allowance to $10,000. Use of the allowance
rose markedly following the repeal of the investment tax credit by the Tax Reform Act of 1986.
The maximum allowance reached $10,000 in 1990, as scheduled, and remained at that amount
until the passage of the Omnibus Budget Reconciliation Act of 1993 (OBRA93, P.L. 103-66).
OBRA93 raised the maximum allowance to $17,500 (as of January 1, 1993) and added a variety
of tax benefits for special areas known as enterprise zones and empowerment zones. One of these
benefits was an expensing allowance for qualified assets placed in service in an EZ that was
$20,000 greater than the regular allowance, with a phaseout threshold twice as large as the
phaseout threshold for the regular allowance. To be designated as an EZ, an area had to meet a
variety of eligibility criteria relating to population, poverty rate, and geographic size.
With the passage of the Small Business Job Protection Act of 1996 (P.L. 104-188), the regular
allowance embarked on yet another upward path. The act raised the maximum allowance to
$18,000 in 1997, $18,500 in 1998, $19,000 in 1999, $20,000 in 2000, $24,000 in 2001 and 2002,
and $25,000 in 2003 and thereafter.
Under the Community Renewal Tax Relief Act of 2000 (P.L. 106-544), Congress expanded the
list of special areas to include renewal communities and granted them the same tax benefits
available to EZs, including an enhanced expensing allowance. The act also increased the
maximum allowance for qualified assets placed in service in a tax year in all special areas
(including RCs) to $35,000 above the regular allowance.
In response to the economic effects of the terrorist attacks of September 11, 2001, Congress
established a variety of tax benefits through the Job Creation and Worker Assistance Act of 2002
(P.L. 107-147) to encourage new business investment in the section of lower Manhattan in New
York City that bore the brunt of the attacks on the World Trade Center. The act designated this

area as the New York “Liberty Zone.” Among the tax benefits offered to firms investing in the
zone was the same enhanced expensing allowance available for qualified investments in EZs and
RCs.
The regular allowance remained on the upward path set down by the Small Business Jobs
Protection Act until the adoption of JGTRRA. Under JGTRRA, the maximum regular allowance
rose four-fold to $100,000 as of May 6, 2003 and was supposed to stay at that amount in 2004
and 2005, before returning to its amount before the enactment of JGTRRA ($25,000) in 2006 and
thereafter. JGTRRA also raised the phaseout threshold to $400,000 over the same period, indexed
both the regular allowance and the threshold for inflation in 2004 and 2005, and added off-theshelf software for business use to the list of depreciable assets eligible for expensing from May 6,
2003 through December 31, 2005.
The American Jobs Creation Act of 2004 (AJCA, P.L. 108-357) extended the changes in the
allowance made by JGTRRA through the end of 2007.
In an effort to spur economic recovery in the areas of Louisiana, Mississippi, and Alabama
devastated by Hurricane Katrina, Congress passed the Gulf Opportunity Zone Act of 2005 (P.L.
109-135). Among other things, the act designated these areas as the Gulf Opportunity Zone
(GOZ) and offered a variety of tax incentives for new business investment in the GOZ, including
an enhanced expensing allowance for qualified assets purchased on or after August 28, 2005, and
placed in service by December 31, 2007. This allowance could be as much as $100,000 above the
regular allowance. In addition, it began to phase out when the total cost of qualified assets placed
in service in a tax year exceeded a threshold that was $600,000 above the phaseout threshold for
the regular allowance. Finally, more assets were eligible for the enhanced allowance than for the
regular allowance.
The Tax Increase Prevention and Reconciliation Act of 2005 (P.L. 109-222) extended the changes
in the allowance made by JGTRRA through 2009.
Under the U.S. Troop Readiness, Veterans’ Care, Katrina Recovery, and Iraq Appropriations Act,
2007 (P.L. 110-28), Congress extended the changes in the allowance made by JGTRRA yet again
(through 2010), raised the maximum allowance to $125,000 and the phaseout threshold to
$500,000 from 2007 through 2010, and indexed both amounts for inflation from 2008 through
2010. The act also extended through 2008 the enhanced expensing allowance for qualified assets
placed in service in the GOZ.
In a bid to boost business investment in the midst of an accelerating downturn in economic
activity, Congress increased the allowance to $250,000 and the phaseout threshold to $800,000
for 2008 only through the Economic Stimulus Act of 2008 (P.L. 110-185). Those amounts return
to $125,000 and $500,000 (both amounts adjusted for inflation) in 2009 and 2010.
The American Recovery and Reinvestment Act of 2009 (P.L. 111-5) extended the enhanced
allowance created by the Economic Stimulus Act of 2008 through 2009.
Legislative Initiatives in the 111th Congress
There are some early signs that congressional interest in enhancing the expensing allowance to
boost small business investment remains as robust as ever in the 111th Congress. Several bills to

extend through 2009 or 2010 the enhanced allowance that was available in 2008 have been
introduced, capped by H.R. 1(ARRA, P.L. 111-5). The version of H.R. 1 signed by President
Obama contains a provision that allows firms to claim a maximum expensing allowance of
$250,000, with a phaseout threshold of $800,000, for qualified assets placed in service in 2009.
The act also extends through 2009 the 50-percent bonus depreciation allowance that applied to
the purchase of qualified assets in 2008.
Economic Effects of the Expensing Allowance
For many lawmakers, the expensing allowance represents a desirable policy tool for lowering the
tax burden on small business owners and stimulating business investment at the same time. And
for many small business owners, the allowance represents a desirable tax benefit. But for most
public finance economists, the allowance generates economic effects that go beyond its impact on
the tax burden of small business owners. In their view, the allowance could affect the allocation
of investment capital within the private sector, the distribution of the federal tax burden among
major income groups, and the cost of tax compliance for smaller firms. These effects correspond
to the three traditional criteria for evaluating tax policy: efficiency, equity, and simplicity. Each is
discussed below.
Efficiency Effects
Efficiency lies at the heart of traditional economic theory and analysis. It refers to the allocation
of resources in an economy and how that allocation shapes the welfare of consumers and
producers. When the allocation of resources produces the greatest possible economic surplus—
defined as the total value to buyers of the goods and services they consume minus the total cost to
sellers of providing these goods and services—the allocation is said to be efficient. But when the
allocation is less than efficient, some of the possible gains from exchange among buyers and
sellers are not realized. For example, economists deem an allocation of resources inefficient when
most suppliers of a good fail to produce it at the lowest marginal cost allowed by existing
technologies. In this case, a shift in sources of supply from relatively high-cost producers to
relatively low-cost producers, driven perhaps by an unleashing of consumer demand, would lower
the total economic cost of providing the good, thereby raising the overall economic surplus.
A policy issue raised by the small business expensing allowance concerns its effect on the
allocation of resources in general and the allocation of investment capital within the private sector
in particular. In theory, all taxes except lump-sum taxes lead to inefficient economic outcomes
because they sway the decisions of consumers and producers in ways that leave one group or the
other—or both—worse off. Non-lump-sum taxes have this effect because they inevitably distort
the economic choices facing individual and business taxpayers, leading them more often than not
to allocate resources on the basis of how taxes affect the cost and benefit of the goods and
services they buy and sell, rather than according to their actual costs and benefits. Such a
distortion entails what economists call a deadweight loss, which is a condition where the amount
of revenue raised by a tax is less than the loss of economic welfare it engenders.
The expensing allowance could affect the allocation of resources in an economy by encouraging
firms to invest in assets that qualify for the allowance, possibly at the expense of other, more
productive assets. There are two channels through which the allowance can produce such an
inefficient outcome. One channel is a reduction in the user cost of capital for investment in

.
Small Business Expensing Allowance
qualified assets relative to investment in all other assets. A second channel is a temporary increase
in the cash flow or retained earnings of firms that acquire qualified assets. Restraining the
allowance’s influence on the allocation of resources is its phaseout threshold, which effectively
confines the benefits of the allowance to relatively small firms.3
Not surprisingly, the user cost of capital plays a major role in a firm’s investment decisions. This
cost embraces both the opportunity cost of an investment and its direct costs, such as
depreciation, the actual cost of the asset, and income taxes. In effect, the user cost of capital
establishes the after-tax rate of return an investment must earn in order to be profitable—and thus
worth undertaking. In general, the higher the user cost of capital, the fewer projects a firm can
profitably undertake, and the lower its desired capital stock. When a change in tax policy
decreases the user cost of capital, it is reasonable to expect many firms to respond by increasing
the amount of capital they wish to own, boosting overall business investment in the short run.
So how does expensing affect the user cost of capital? Expensing is the most accelerated form of
depreciation. Under expensing, the entire cost of an asset is written off in its first year of use,
regardless of the asset’s economic or useful life. Allowing a firm to expense its acquisition of an
asset is akin to the U.S. Treasury providing the firm with a tax rebate equal to the firm’s marginal
tax rate multiplied by the cost of the asset. Accelerated depreciation—along with other investment
tax subsidies such as an investment tax credit—reduces the user cost of capital by lowering the
pre-tax rate of return on investment a firm must earn in order to realize a particular after-tax rate
of return. 4 Expensing yields the largest possible reduction in the user cost of capital from
accelerated depreciation. As some studies have shown, this reduction can be considerable.5
How beneficial is expensing? One way to illustrate the tax benefit from expensing is to assess
how it affects the marginal effective tax rate on the returns to investment in an asset whose cost is
expensed. Expensing has the effect of taxing the stream of income earned by an asset over its
lifetime at a marginal effective rate of zero. 6 This is because expensing reduces the after-tax
3
According to unpublished IRS estimates, a total of $55.161 billion in assets eligible for the IRC Section 179
expensing allowance were placed in service in 2003. Firms with assets of $10 billion or less accounted for 49% of this
investment, whereas firms with assets of $100 billion or more accounted for 16%.
4
The user cost of capital is the real rate of return an investment project must earn to be profitable. In theory, a firm will
undertake an investment provided the after-tax rate of return exceeds or at least equals the user cost of capital. Rosen
has expressed this cost in terms of a simple equation. Let C stand for the user cost of capital, a for the purchase price of
an asset, r for the after-tax rate of return, d for the economic rate of depreciation, t for the corporate tax rate, z for the
present value of depreciation deductions flowing from a $1 investment, and k for the investment tax credit rate. Then
C = a x [(r +d) x (1-(t x z)-k)]/(1-t). Under expensing, z is equal to one. By plugging assumed values for each variable
into the equation, one sees that C increases as z gets smaller. Thus, of all possible methods of depreciation, expensing
yields the lowest user cost of capital. For more details, see Harvey S. Rosen, Public Finance, 6th ed (New York:
McGraw-Hill/Irwin, 2002), pp. 407-409.

In a 1995 study, Douglas Holtz-Eakin compared the cost of capital for an investment under two scenarios for cost
recovery. In one, the corporation making the investment used expensing to recover the cost of the investment; and in
the other, the cost was recovered under the schedules and methods permitted by the modified accelerated cost recovery
system. He further assumed that the interest rate was 9%, the inflation rate 3%, and the rate of economic depreciation
for the asset acquired through the investment 13.3%. Not only did expensing substantially reduce the cost of capital, its
benefit was proportional to the firm’s marginal tax rate. Specifically, Holtz-Eakin found that at a tax rate of 15%,
expensing lowered the cost of capital by 11%; at a tax rate of 25%, the reduction was 19%; and at a tax rate of 35%, the
cost of capital was 28% lower. See Douglas Holtz-Eakin, “Should Small Businesses Be Tax-Favored?” National Tax
Journal, September 1995, p. 389.

Small Business Expensing Allowance
return and cost for an investment by the same factor, which is an investor’s marginal tax rate. For
example, if the income received by a small business owner is taxed at a rate of 35% and the cost
of a depreciable asset he or she buys is recovered through expensing, then the federal government
effectively becomes a partner in the investment with an interest of 35%. Through the tax code, the
federal government assumes 35% of the cost of the asset by allowing its entire cost to be
deducted in the first year of the asset’s use, and it receives 35% of the income earned by the
investment in subsequent years. Conversely, expensing allows the small business owner to
receive 65% of the returns from the investment but to bear only 65% of the cost. Such an
outcome implies that for each dollar spent on the asset, the owner earns the same rate of return
after taxes as before taxes.7 This equivalence implies that expensing results in an effective
marginal tax rate of 0.
Expensing could also spur a rise in business investment by augmenting the cash flow of firms that
rely heavily on retained earnings to finance their investments.8 Expensing can increase a firm’s
cash flow in the short run because it allows the firm to deduct the full cost of qualified assets in
the tax year the firm places them into service. There are several reasons why a firm’s investments
could depend on its cash flow. One is that the firm’s owners or senior managers want to limit their
exposure to external debt and the risk of default it entails. Another reason is that the firm has
limited or virtually no access to debt and equity markets, because potential investors and lenders
lack sufficient information about the firm’s products and competitive strategies. For firms in such
a position, the cost of internal funds could be lower than the cost of external funds, in which case
the firm clearly would be better off financing its investments out of retained earnings.
Nevertheless, the impact of increases in cash flow on business investment remains uncertain.
Some studies found a significant positive correlation between changes in a firm’s net worth and
its investment spending.9 This correlation was strongest for firms that had very limited access to
debt and equity markets. Yet it would be a mistake to interpret these findings as proof that firms
with relatively high cash flows invest more than firms with relatively low or negative cash flows.
After all, a strong correlation between two factors does not prove the existence of a cause-andeffect relationship between them. It may be the case that firms with relatively high cash flows
invest more, on average, than firms with relatively low cash flows for reasons that have little or
nothing to do with the relative cost of internal and external funds. The relationship between cash
flow and business investment is complicated, and further research is needed to clarify it.
Has the expensing allowance made significant contributions to shifts in the size and composition
of the domestic capital stock in the 25 years the allowance has existed in its present form? This
question is difficult to answer, largely because there are no studies analyzing the impact of the
allowance on capital formation over time, and available empirical evidence is incomplete. Given
that the expensing allowance lowers the cost of capital and may boost cash flow for firms using it,
and that investment in many of the assets eligible for the allowance seems somewhat sensitive to
changes in the cost of capital, one might be justified in concluding that the allowance has caused

Small Business Expensing Allowance
domestic investment in those assets to be greater than it otherwise would have been. 10 But there
are some compelling reasons to argue that much of this investment would have taken place
without the expensing allowance.11 Most economists would be likely to agree that investment in
assets eligible for the expensing allowance is driven more by expectations for future growth in
sales by firms that purchase these assets, the nature of the assets, and conditions in debt and
equity markets than by tax considerations. 12 This view finds some support in available data on use
of the expensing allowance: although 22% of corporations filing federal tax returns claimed the
allowance from 1999 through 2003, the total value of IRC Section 179 property placed in service
in that period was equal to only 5% of domestic gross investment in equipment and computer
software.13
When seen through the lens of conventional economic theory, the expensing allowance has
efficiency effects that may worsen the deadweight loss caused by the federal tax code. Under the
reasonable assumption that the amount of capital in the economy is fixed in the short run, a tax
subsidy like the allowance is likely to lure some capital away from highly profitable uses and into
tax-favored uses. Conventional economic theory holds that in an economy free of significant
market failures and dominated by competitive markets, a policy of neutral or uniform taxation of
capital income minimizes the efficiency losses associated with income taxation. But the
expensing allowance encourages investment in specific assets by relatively small firms. Such a
subsidy can interfere with the flow of financial capital to its most profitable uses by making it
possible for business owners to earn higher after-tax rates of return on investment in assets
eligible for the allowance than on investment in other assets with higher pre-tax rates of return.
In addition, the expensing allowance gives smaller firms an incentive to limit their growth. This
unintended effect stems from the rise in marginal effective tax rates on the income earned by an
asset eligible for the allowance in the allowance’s phaseout range ($530,000 to $663,000 in
2009).14 Douglas Holtz-Eakin, a former Director of the Congressional Budget Office, has called
this incentive effect a “tax on growth by small firms.”15
10
Two studies from the 1990s found that a 1% decline in the user cost of capital was associated with a rise in business
equipment spending of 0.25% to 0.66%. See CRS Report RL31134, Using Business Tax Cuts to Stimulate the
Economy, coordinated by Jane G. Gravelle, p. 4.
11
There is some anecdotal evidence to support this supposition. At a recent hearing held by the House Small Business
Subcommittee on Tax, Finance, and Exports, Leslie Shapiro of the Padgett Business Services Foundation stated that
expensing “may be an incentive in making decisions to buy new equipment, but it’s not the dominant force.” His firm
provides tax and accounting services to over 15,000 small business owners. See Heidi Glenn, “Small Business
Subcommittee Weighs Bush’s Expensing Boost,” Tax Notes, April 7, 2003, p. 17.

Jane Gravelle of CRS has estimated that, with a corporate tax rate of 28% and a rate of inflation of 3%, the marginal
effective tax rate on the income earned by assets eligible for the expensing allowance is 36% in the phase-out range for
the allowance. By contrast, under the same assumptions, the marginal effective tax rate on the income earned by
qualified assets is 0% for each dollar of investment in those assets up to $430,000.

Small Business Expensing Allowance
Equity Effects
Equity is another basic concept in conventional economic analysis. It generally refers to the
distribution of income among the individuals or households in a particular geographic area.
In the context of income taxation, equity usually denotes the distribution of the tax burden among
taxpayers divided into income groups. Economists who analyze the equity effects of income taxes
tend to focus on two distinct kinds of equity: horizontal equity and vertical equity. A tax is said to
be horizontally equitable if it imposes similar burdens on individuals with similar incomes or
living standards. And a tax system is said to be vertically equitable if the burdens it imposes vary
according to an individual’s or household’s ability to pay. The principle of vertical equity lays the
foundation for a progressive income tax system. Under such a system, an individual’s tax liability,
measured as a fraction of income, rises with income.
The current federal income tax system arguably leans more in the direction of vertical equity than
horizontal equity. Many individuals with similar incomes before taxes end up being taxed at the
same marginal rate. But because so many tax preferences in the form of deductions, preferential
rates, deferrals, exclusions, exemptions, and credits have been enacted in recent decades, a
significant share of individuals with similar before-tax incomes end up being taxed at different
rates. At the same time, those with relatively high pre-tax incomes are generally taxed at higher
rates than those with relatively low pre-tax incomes.
How does the expensing allowance affect vertical and horizontal equity?
To answer this question, it is necessary to consider the tax benefits associated with the expensing
allowance, who receives them, and how they affect the recipients’ federal income tax burdens.
The main tax benefit from the allowance is a reduction in the marginal effective tax rate on the
income earned by assets eligible for expensing. How much of a reduction depends critically on
the proportion of an asset’s cost that is expensed. As was noted earlier, if the entire cost is
expensed, then the marginal effective rate falls to zero. Yet the allowance does not change the
actual marginal rates at which this income is taxed. This is because accelerated depreciation does
not reduce the total amount of taxes (measured in current dollars) owed on the stream of income
earned by an asset over its useful life. Rather, accelerated depreciation simply moves forward the
timing of depreciation deductions in a way that substantially raises the present discounted value
of the tax savings from depreciation deductions.
Most of the assets eligible for the allowance are held by smaller firms. Therefore, it seems
reasonable to conclude that most of the tax savings attributable to the allowance ends up in the
pockets of small business owners. But such a conclusion is somewhat misleading, as the
allowance does not alter the income tax rates that apply to the income earned by small business
owners—and thus has no direct effect on the distribution of the federal income tax burden among
income groups. Nonetheless, the allowance does lower the tax burden on the returns to a portion
of small business investment, which means that the allowance may indirectly violate the principle
of vertical equity by decreasing the effective tax rate on income earned by small business owners.
Tax Administration
Yet another policy question raised by the expensing allowance concerns its impact on the cost of
tax compliance for business taxpayers.
Congressional Research Service

Small Business Expensing Allowance
Most public finance economists agree that a desirable income tax system is one that imposes
relatively low costs for administration and compliance. Research indicates that the administrative
cost of a tax system hinges on three factors: (1) the records that must be kept in order to comply
with tax laws, (2) the complexity of those laws, and (3) the types of income subject to taxation.
Most public finance economists also agree that the current federal income tax system fails this
test. In their view, the costs of collecting income taxes and enforcing compliance with the tax
laws are needlessly high, and the primary cause is the growing complexity of the federal tax code.
Many small business owners have long complained about the costs imposed on them by the
record keeping and filings required by the federal income tax.
The expensing allowance addresses this concern by simplifying tax accounting for the firms that
claim it. Less time and paperwork are involved in writing off the entire cost of a depreciable asset
in its first year of use than in writing off that cost over a longer period using allowable
depreciation schedules. At the same time, the rules governing the use of the regular allowance and
the use of the allowance in special areas like EZs and RCs add a layer of complexity to the
administration of the tax code by the IRS.
Tax simplification is a longstanding policy objective for a majority of small business owners. A
primary motivation for this quest is the relatively high costs small firms evidently bear in
complying with federal tax laws. These costs were the main focus of a 2001 study prepared for
the Office of Advocacy at the Small Business Administration. The study found that the cost per
U.S. employee for tax compliance in 2000 was an estimated $665 for all firms, $1,202 for firms
with fewer than 20 employees, $625 for firms with 20 to 499 employees, and $562 for firms with
500 or more employees. 16 This finding appears to lend further support to what is regarded as a
well-established truth about the costs to firms of tax compliance: namely, that these costs are17
regressive to firm size in that “as a fraction of any of a number of size indicators, the costs are
lower for larger companies.”
