An Overview of Tax Provisions Expiring in 2012

Summary
A number of tax provisions either expired in 2011 or are scheduled to expire at the end of 2012.
These include the following:
• The Bush tax cuts, which reduced income taxes by reducing tax rates, reducing
the marriage penalty, repealing limitations on personal exemptions and itemized
deductions (PEP and Pease, respectively), expanding refundable credits, and
modifying education tax incentives. The Bush tax cuts also reduced estate tax
liabilities by increasing the amount of an estate exempt from taxation and by
lowering the tax rate.
• The alternative minimum tax (AMT) patch, which, by increasing the amount of
income that is exempt from the AMT and allowing certain personal credits
against the AMT, prevents an estimated 26 million additional taxpayers from
owing the AMT.
• The payroll tax cut, which reduced an employee’s share of Social Security taxes
by two percentage points.
• A variety of previously extended temporary tax provisions, commonly referred to
as “tax extenders,” which affect individuals, businesses, charitable giving,
energy, community development, and disaster relief.
As Congress decides whether to extend these provisions, it may consider the estimated revenue
losses associated with their extension. The Congressional Budget Office (CBO) estimated that
extending these provisions through 2022, except for the payroll tax cut, which CBO assumes
expires as scheduled at the end of 2012, would reduce revenues by $5.4 trillion between 2013 and
2022. Specifically, over this 10-year budgetary window extending the Bush tax cuts and
extending the AMT patch would reduce revenues by $4.6 trillion, while extending the tax
extenders would reduce revenues by $839 billion. The cost of extending the payroll tax cut for
one year (2012) was estimated to be $114 billion over the 2012-2022 budgetary window.
In addition to budgetary cost, Congress may also consider other factors when evaluating tax
policy. For example, when considering extending the Bush tax cuts, policy makers might consider
that the majority of the benefits of this policy accrued to the top 20% of taxpayers. They might
also evaluate the potential contractionary impact the expiration of these cuts in 2013 may have on
the economy, especially since both the scheduled expiration of the payroll tax cut and the
enactment of budget cuts as part of the Budget Control Act (P.L. 112-25) are scheduled to go into
effect at the same time. Similarly, Congress may examine the cost effectiveness of the payroll tax
cut. According to CBO, the short-term stimulus impact of the payroll tax cut is lower than
increasing aid to the unemployed or providing additional refundable tax credits to low- and
middle-income households, but more stimulative than extending the Bush tax cuts. Finally,
Congress may weigh the lower budgetary costs of short-term extensions of tax extenders against
the unpredictability for taxpayers that can arise from short-term extensions.
In past years, Congress has extended expiring provisions en masse in one legislative vehicle. In
the 112th Congress, Members have considered legislation to extend certain provisions, including
S. 3412, S. 3413, and H.R. 8, which extend some or all of the Bush tax cuts and the AMT patch.
In addition, the Senate may consider S. 3521, which extends certain temporary expiring
provisions.

An Overview of Tax Provisions Expiring in 2012

Introduction
A number of tax provisions have either expired at the end of 2011 or are scheduled to expire at
the end of this year.1 These include the Bush tax cuts, the alternative minimum tax (AMT) patch,
the temporary payroll tax cut, and other temporary expiring provisions, many of which are
commonly referred to as “tax extenders.” Aside from the payroll tax cut, which was extended by
the Middle Class Tax Relief and Job Creation Act of 2012 (P.L. 112-96), the most recent law
extending many of these provisions was the Tax Relief, Unemployment Insurance
Reauthorization and Job Creation Act of 2010 (P.L. 111-312).
This report provides an overview of these expiring provisions. For each provision (or group of
provisions), this report first describes the provision (“current law”), followed by a brief overview
of legislation related to the provision, then outlines its past cost and if available the cost of its
extension (“budgetary cost”), and concludes with a brief discussion of the current debate
concerning the policy (“policy debate”). In the case of the Bush tax cuts and tax extenders, where
the policies comprise a variety of other provisions, the details of the provisions are provided in
accompanying tables.
In past years, Congress has extended expiring provisions en masse in one legislative vehicle.2 In
the 112th Congress, Members have yet to consider legislation that would extend all of the
provisions discussed in this report past their scheduled expiration, although legislation to extend
certain provisions has been considered.3 Specifically, Congress has considered S. 3412, S. 3413,
and H.R. 8, which extend some or all of the Bush tax cuts and the AMT patch. On July 25, 2012,
the Senate agreed to S. 3412 by a vote of 51-48, while they rejected an amendment identical to S.
3413 (S.Amndt. 2573 to S. 3412) by a vote of 45-54. Any further action would be on a house-
originated tax measure. On August 1, 2012, the House agreed to H.R. 8. In addition, the Senate
may consider S. 3521, which extends “tax extenders,” other temporary expiring provisions, and
the AMT patch.

1 This report does not include the budgetary impact of every policy that is scheduled to expire in the next two years.
For more information on other policies that are set to expire, see Table 27-6 in the Analytical Perspectives of the
President’s FY2012 Budget. In addition, for a list of expiring tax provisions, see Joint Committee on Taxation, List Of
Expiring Federal Tax Provisions 2010-2020, JCX-2-11.
2 For example, at the end of 2010, Congress enacted the payroll tax cut and extended the Bush tax cuts, the AMT-patch
and tax extenders as part of P.L. 111-312. In 2008, Congress extended the AMT patch and certain tax extenders as part
of the Emergency Economic Stabilization Act of 2008 (EESA; P.L. 110-343). For other extending legislation, see
Table 1 in CRS Report R42105, Tax Provisions Expiring in 2011 and “Tax Extenders,” by Molly F. Sherlock.
3 For example, on March 13, 2012, the Senate considered senate amendment 1812 to S. 1813. Senate amendment 1812
proposed extending certain energy tax extenders. This amendment was not agreed to. In addition, the extension of the
payroll tax cut through the end of 2012 was enacted in the 112th Congress.

Bush Tax Cuts
Current Law
The Bush tax cuts were provisions—enacted into law primarily by the Economic Growth and Tax
Relief Reconciliation Act of 2001 (EGTRRA; P.L. 107-16) and the Jobs Growth Tax Relief
Reconciliation Act of 2003 (JGTRRA; P.L. 108-27)—which gradually reduced individual income
and estate tax liabilities between 2002 and 2010.4,5 These tax cuts were extended for 2011 and
2012 by the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010
(P.L. 111-312), henceforth referred to as the 2010 Tax Act. Notably, the 2010 Tax Act was enacted
under President Obama, not President Bush, although the underlying policy is still commonly
referred to as the Bush tax cuts.

• modifying education tax incentives, including Coverdell education saving
accounts (ESAs), the student loan interest deduction, and the tax treatment of
certain scholarships and fellowships. The Bush tax cuts also created an exclusion
for employer-provided educational assistance.
The Bush tax cuts also gradually reduced the estate tax8 between 2002 and 2009, with a full
repeal of the estate tax in 2010. Under EGTRRA, the amount of an estate which was exempt from
taxation gradually rose from $1 million per decedent in 2002 to $3.5 million per decedent9 in
2009, while the top tax rate under the estate tax fell from 50% to 45% over the same time period.
In 2010, for the first time since 1916, there was no federal estate tax. The 2010 Tax Act reinstated
the estate tax, but raised the exemption level and lowered the tax rate in comparison to the estate
tax in effect in 2009. Specifically, the exemption amount in 2011 was set at $5 million per
decedent (adjusted for inflation, this amount will equal $5,120,000 per decedent in 2012) and the
top tax rate was set at 35%. The estate tax is scheduled to increase in 2013, with a $1 million per
decedent exemption level and 55% top tax rate.
Finally, the American Recovery and Reinvestment Act of 2009 (ARRA; P.L. 111-5) made
modifications to two provisions of the Bush tax cuts and enacted two new tax provisions.
Specifically, ARRA’s modifications expanded the refundability of the child tax credit and further
reduced the marriage penalty of the EITC (described in Table 1). These changes were extended
along with the Bush tax cuts by the 2010 Tax Act. In addition, ARRA increased the EITC for
families with three or more children10 and enacted a new higher education tax credit—the
American Opportunity Tax Credit (AOTC).11 These tax law changes were also extended through
the end of 2012 by the 2010 Tax Act.
Legislation Considered to Extend the Bush Tax Cuts
The Senate and the House have considered legislation to extend some or all of the Bush tax cuts
and the AMT patch. Specifically, S. 3413 and H.R. 8 would extend all of the current Bush tax cuts
(these bills differ on their treatment of a business expensing provision) and extend the current
parameters of the estate and gift tax. S. 3412 would extend the Bush tax cuts for taxpayers
making under $200,000 for single filers, $225,000 for head of household filers, and $250,000 for
married joint filers. In addition, while this bill would not extend the current parameters of the
estate tax, it would extend certain ARRA tax provisions.12 A detailed overview of these bills and a
comparison of specific provisions can be found in CRS Report R42622, An Overview and

8 EGTRRA also phased out generation-skipping taxes over a 10-year period, with the gift tax the only federal transfer
tax in effect in 2010. For more information on the estate tax, generation-skipping taxes and the gift tax, see CRS Report
95-416, Federal Estate, Gift, and Generation-Skipping Taxes: A Description of Current Law, by John R. Luckey.
9 These exemption amounts are per decedent and a surviving spouse may also use any unused applicable exclusion
amount of their spouse.

11 For more information on the American Opportunity Tax Credit, see CRS Report R41967, Higher Education Tax
Benefits: Brief Overview and Budgetary Effects, by Margot L. Crandall-Hollick.
12 Specifically, S. 3412 would extend ARRA provisions that expanded the refundability of the child tax credit, reduced
the marriage penalty of the EITC, increased the EITC for families with three or more children, created a new higher
education tax credit (the American Opportunity Tax Credit), and disregarded tax refunds and refundable credits in the
administration of means-tested Federal programs.

Comparison of Proposals to Extend the “Bush Tax Cuts”: S. 3412, S. 3413, H.R. 8, by Margot L.
Crandall-Hollick.
Budgetary Cost
The 2010 Tax Act’s two-year extension of the income and estate tax provisions of the Bush tax
cuts (including the four ARRA modifications) reduced revenues by $475.79 billion over a 10-year
budgetary window (2011-2020).13 Of these revenue losses, $363.55 billion is attributable to the
extension of the income tax provisions of EGTRRA and JGTRRA, $68.15 billion is attributable
to the modified estate tax provision, and $44.10 billion is attributable to the four ARRA tax
provisions discussed above.14 The Congressional Budget Office (CBO) estimated that the
extension of the income and estate tax provisions15 of the Bush tax cuts and the four ARRA tax
provisions through 2022 would cost $2.84 trillion over a 10-year budgetary window (2013-
2022).16 The debt service associated with extending these provisions was estimated to be $505
billion over the same time period.
Under S. 3412—which extends the Bush tax cuts for those with income under $200,000 (single
filers)/$250,000(married joint filers)—the revenue losses from extending the EGTRRA and
JGTRRA individual income tax provisions for 2013 are estimated to be $129.53 billion over the
10-year budgetary window of 2013 through 2022. In addition, the revenue losses from extending
temporary tax cut provisions included in ARRA for 2013 are estimated to be $27.22 billion over
the 10-year budgetary window of 2013 through 2022. (Neither H.R. 8 nor S. 3413 would extend
these ARRA provisions.) The equivalent revenue losses under S. 3413—which extends the Bush
tax cuts for all income levels—are estimated to be $177.49 billion between 2013 through 2022.
The equivalent revenue losses under H.R. 8 (which also extends the Bush tax cuts for all income
levels) are estimated to be $178.63 billion between 2013 through 2022.17 The extension of the
current parameters of the estate and gift tax for 2013 included in S. 3413 and H.R. 8 is estimated
to result in $31.21 billion in revenue losses between 2012 through 2022.
Policy Debate
Supporters and opponents of the Bush tax cuts generally evaluate the Bush tax cuts from different
perspectives. Supporters of the tax cuts stress their long-term and short-term economic benefits.
Opponents often emphasize that the tax cuts are costly in terms of reduced revenues and that the
benefits of this policy disproportionally accrue to the highest income taxpayers.

An Overview of Tax Provisions Expiring in 2012

When the Bush tax cuts were originally proposed, proponents stressed that by reducing marginal
tax rates, this policy would lessen some of the distortions taxes had on work, saving, and
investment, ultimately boosting long-term growth. For example, by reducing marginal tax rates,
individuals would have more take-home pay, theoretically incentivizing them to work more.
Ultimately, this increased economic activity would boost long-term economic growth. Some
critics have sought to disprove this theory by comparing historical growth rates and marginal tax
rates in the United States. They argue that in periods when taxes where raised (the mid to late
1990s for example), growth was higher than in periods when taxes were cut (the 2000s for
example). However, comparing growth rates during periods with different tax rates does not
necessarily prove that tax policy did not impact growth since a variety of other factors, aside from
tax rates, differ between these time periods. The results of many economic studies, have shown
that tax cuts generally do affect growth (and components of growth).18 They have also generally
shown, however, that the impact of tax cuts on growth is small in relation to the foregone revenue
resulting from the cut.19
When the Bush tax cuts were being considered by Congress in 2001, the economy had slipped
into a recession. Tax-cut advocates were highlighting the short-term stimulative benefits of the
tax cuts. Estimates prepared at the time the Bush tax cuts were being considered predicted a
short-term stimulative effect.20 In addition, CBO analysis indicated that reductions in individual
income tax rates could have short-term stimulative impacts on the economy, although these
effects were estimated to be small.21 Later analysis concluded that “the tax cuts reduced GDP
[gross domestic product] and employment in 2001, and had virtually no effect on those
aggregates in 2002.”22 More recent estimates by CBO concluded that the tax cuts had limited

18 In a later analysis of the budgetary cost of the Bush tax cuts, CBO stated: “The policies [Bush tax cuts] undoubtedly
exerted at least some influence on the economy…Those economic feedbacks on today’s budget, however, are likely to
be modest.” For more information, see Congressional Budget Office, Letter to the Honorable John M. Spratt, Jr., July
20, 2007, http://www.cbo.gov/sites/default/files/cbofiles/ftpdocs/83xx/doc8337/07-20-egtrra-jgtrra_and_deficits.pdf.
19 Lowering marginal tax rates would theoretically increase the amount taxpayers work and so would theoretically
increase their income (all else being equal). The sensitivity of income to changes in marginal tax rates is referred to as
elasticity. An elasticity less than one implies that changes in taxpayers’ income were proportionally less than the
changes in the tax rate, while an elasticity greater than one implies that income gains are proportionally larger than the
tax cut. A recent review of other studies found that the elasticity of income to tax rate changes was between 0.12 and
0.40. Since the resulting increase in income is proportionally smaller than the cut in marginal rates, government
revenues will fall as a result of the cut. See Emmanuel Saez, Joel Slemrod, and Seth Giertz, “The Elasticity of Taxable
Income with Respect to Marginal Tax Rates: A Critical Review,” Journal of Economic Literature, vol. 50, no. 1
(2012), pp. 42. Similarly, CBO found that a 10% tax rate cut would offset between 5% and 32% of the cost of cut in
terms of revenue losses over the second 5 years of a year budgetary window. For more information, see Congressional
Budget Office, Analyzing the Economic and Budgetary Effects of a 10 Percent Cut in Income Tax Rates, Economic and
Budget Issue Brief, December 1, 2005, http://www.cbo.gov/sites/default/files/cbofiles/ftpdocs/69xx/doc6908/12-01-
10percenttaxcut.pdf. In so far as tax cuts are deficit-financed, they may actually negatively impact growth. For
example, the Joint Committee on Taxation, in modeling the economic effects of reducing individual and corporate tax
rates, found that “Growth eventually become(s) negative without offsetting fiscal policy…because accumulating
Federal government debt crowds out private investment.” Joint Committee on Taxation, Macroeconomic Analysis of
Various Proposals to Provide $500 Billion in Tax Relief, JCX-4-05, March 1, 2005, p. 2.

Economy?, by Marc Labonte.
21 According to CBO, a 10% cut in income tax rates would result in economic changes that would offset between 1%
and 22% of the revenue loss from the tax cut over the first five years.” For more information, see Congressional Budget
Office, Analyzing the Economic and Budgetary Effects of a 10 Percent Cut in Income Tax Rates, Economic and Budget

stimulative benefit—estimating that every $1 dollar of Bush tax cuts resulted in 10 to 60 cents of
GDP.23 Yet, while the Bush tax cuts may not have been an effective short-term stimulus in
response to a recession, some economists warn that allowing these tax cuts to expire in 2013, at
the same time as a scheduled fiscal contraction, may have a negative effect on the economy.24
Opponents of the Bush tax cuts highlight both their high cost as well as the fact that most of the
benefits go to upper-income taxpayers. Recent estimates by CBO indicate that the Bush tax cuts,
whose cost were not offset, increased the deficit by $1.75 trillion over the past 10 years (2002-
2011).25 Estimates indicate that approximately two-thirds of the benefits of these cuts accrued to
the top 20% of taxpayers with the highest income26 and over one quarter (26.5%) of the benefits
of the Bush tax cuts accrued to the top 1%.27 By contrast less than a fifth of the benefits (16.5%)
accrued to the bottom 60% of taxpayers.28 Critics charge that this distribution of benefits is
“unfair.” In response, supporters of the tax cuts approach the “fairness” of the tax cuts from a
different perspective. They highlight that higher income taxpayers pay a greater share of federal
taxes, and the tax cut was fair in so far as it benefitted the taxpayers with the highest tax burdens.
According to CBO, the top 20% of households in the income distribution pay more than two-
thirds (68.9%) of all federal tax liabilities, while the top 1% of households pays more than a
quarter of all Federal taxes (28.1%).29
Another perspective on the “fairness” of these tax cuts that opponents of this policy highlight is
their distributional impact on after-tax income. According to estimates examining tax burdens in
2010, the Bush tax cuts resulted in the lowest 20% of taxpayers seeing their income rise by 0.5%,
while the top 20% saw their after-tax incomes rise by 4.9% and the top 1% saw their income rise
by 6.6%.30

spending cuts included in the Budget Control Act which go into effect in 2013 and combined expiration of extended
unemployment insurance benefits, the payroll tax cuts, and the Bush tax cuts in 2013 will reduce real GDP growth by
nearly 3 percentage points in 2013. See http://jec.senate.gov/public//index.cfm?a=Files.Serve&File_id=df8f2728-94fa-

The distributional impact of the Bush tax cuts may be relevant to policy makers if they are
concerned with growing income inequality in the United States.31 A recent CBO report
highlighted that while the main driver of increasing after-tax income inequality was the increasing
concentration of pre-tax income among the wealthiest Americans, government transfers and
federal tax policy also contributed to the growth of after-tax income inequality.32 As the CBO
report indicated, the equalizing impact of taxes depends on their progressivity,33 with increasing
progressivity reducing income inequality (holding the size of tax receipts constant).34 The Bush
tax cuts overall reduced the progressivity of federal income taxes35 and hence were a factor in
increases in income inequality in the United States.
When evaluated separately, some Bush tax cut provisions increased income inequality, while
others contributed to a decrease in income inequality. Recent CRS analysis found that the
lowering of tax rates, the repeal of PEP and Pease, and the reduced taxes on capital gains and
dividends increased income inequality. Alternatively, the expansion of the child tax credit and
EITC were found to reduce income inequality.36

a. EGTRRA also included an employer-provided child care credit for businesses taxpayers and allowed Alaska Native Settlement Trusts to tax income to the trust, not
the beneficiaries. These provisions, which were original y scheduled to expire at the end of 2010, were extended through the end of 2012 by P.L. 111-312.
b. The Emergency Economic Stabilization Act (EESA; P.L. 110-343) lowered the refundability threshold to $8,500 for 2008.
c. EGTRRA increased the dollar limitation on the credit and the exclusion for employer-provided adoption assistance to $10,000 (indexed to inflation after 2002) for all
adoptions and increased the income phase-out starting point to $150,000 (indexed for inflation after 2002). Both of these modifications were set to expire at the end
of 2010. The Patient Protection and Affordable Care Act (P.L. 111-148) increased the maximum amount of the credit to $13,170 for tax year 2010, with this amount
indexed for inflation for 2011, and made the adoption credit refundable for 2010 and 2011. For more information, see CRS Report RL33633, Tax Benefits for Families:

d. EGTRRA also increased the arbitrage rebate exception from $10 million to $15 million for government bonds used to finance qualified school construction and
allowed for the issuance of tax exempt private activity bonds for qualified education facilities.
e. In the absence of this provision, taxpayers may still be able to exclude certain employer-provided educational assistance. Specifically, taxpayers can exclude employer-
provided education assistance if it qualifies as a working condition fringe benefit. Generally, education expenses are qualify as a working condition fringe benefit if they
would have been deductible under section 162 of the internal revenue code (IRC) and the employer paid them. According to section 162, qualifying education
expenses are those associated with education that (1) maintains or improves a skill required in a trade or business of the taxpayer or (2) meets the requirements of
taxpayer’s employer, applicable law or regulation imposed as a condition of continued employment.

An Overview of Tax Provisions Expiring in 2012

AMT Patch
Current Law
The Alternative Minimum Tax (AMT) was designed to ensure that higher-income taxpayers who
owed little or no taxes under the regular income tax because they could claim tax preferences
would still pay some tax.37 When calculating the AMT, taxpayers first add back various “tax
preference items” (like certain deductions) to their taxable income, to determine the amount of
income subject to the AMT (the “AMT tax base”). Second, taxpayers subtract a basic exemption
amount from their AMT tax base. Third, a two-tiered rate structure of 26% and 28% is assessed
against the AMT tax base to determine tax liability. Finally, if a taxpayer’s AMT is greater than
their regular tax liability, the taxpayer pays the difference in addition to their regular tax liability
(the difference paid is technically the AMT). Crucially, unlike the regular income tax, key parts of
the AMT—including the exemption amounts—are not indexed for inflation. This means in a
typical year, as a result of inflation increasing taxpayers’ nominal income levels, additional
taxpayers are subject to the AMT.
The Bush tax cuts temporarily increased the exemption amount under the AMT. This temporary
increase in the exemption amount, known as the AMT patch, was extended several more
times38—most recently by P.L. 111-312—and was in effect through the end of 2011.39 In 2011,
the AMT-exemption amounts were $74,450 for married individuals filing joint returns and
$48,450 for unmarried individuals. These exemption amounts revert to $45,000 for married
individuals and $33,750 for unmarried individuals in 2012.40 In addition, an AMT patch generally
has also included a provision which allowed taxpayers to reduce their AMT by nonrefundable
personal tax credits.41 In 2012, under current law, most nonrefundable personal credits will no
longer be allowed against the AMT.
Legislation Considered to Extend the AMT Patch
The Senate and the House have considered legislation to extend the AMT patch as part of broader
legislation to extend some or all of the Bush tax cuts. S. 3412 would extend the AMT patch for
one year, 2012, while S. 3413 and H.R. 8 would extend the AMT patch for two years, 2012 and
2013. Under all three bills, the exemption amounts in 2012 would be raised to $50,600 for
individuals and $78,750 for married joint filers. S. 3413 and H.R. 8 would raise the exemption

it for 2011.

amounts to $51,150 for individuals and $79,850 for married joint filers. In addition all three bills
would allow nonrefundable personal credits against the AMT for 2012, and S. 3413 and H.R. 8
would also allow nonrefundable credits against the AMT in 2013. A detailed overview of these
bills and a comparison of these three bills can be found in CRS Report R42622, An Overview and
Comparison of Proposals to Extend the “Bush Tax Cuts”: S. 3412, S. 3413, H.R. 8, by Margot L.
Crandall-Hollick.
The Senate may consider legislation to extend certain expiring tax provisions and tax extenders.
This legislation, S. 3521, the Family Business and Tax Cut Certainty Act of 2012, would also
extend the AMT patch for two years—2012 and 2013.
Budgetary Cost
The cost of AMT patches will depend on whether current tax policy (i.e., the Bush tax cuts) is
also extended. Generally, for taxpayers subject to the AMT, the lower their taxes under the regular
income tax system, the higher their AMT and, hence, the greater the cost to patch the AMT. Thus,
the cost of AMT patch would be expected to be higher if the Bush tax cuts—which generally
lowered taxes—were in effect as compared to if they were not in effect, all else being equal. CBO
estimates indicate that revenue losses from extending the AMT-patch concurrently with the Bush
tax cuts are larger than only extending the AMT-patch and allowing the Bush tax cuts to expire.
The cost of indexing the AMT to inflation through 2022, assuming current law (i.e., the Bush tax
cuts expire), is estimated to be $804 billion over 10 years, 2013-2022 (plus an additional $133
billion in debt service over the same time period).42 CBO estimated that the combined cost of the
extension of the Bush tax cuts and the AMT patch would be $920 billion more than the sum of
extending these policies separately, highlighting the interaction between the regular income tax
and AMT previously discussed. Specifically, the cost of extending the Bush tax cuts was
estimated to be $2.84 trillion over 10 years (2013-2022), while the cost of extending the AMT
patch was estimated to be $804 billion over the same time period. The cost of extending the
policies concurrently was estimated to be $4.56 trillion between 2013 and 2022 (the debt service
associated with a concurrent extension of the Bush tax cuts and the AMT patch was estimated to
be an additional $790 billion between 2013 and 2022).43
The revenue losses from extending the AMT patch for one year—2012—included as part of S.
3412 (which extended some of the Bush tax cuts for 2013) are estimated to be $92.04 billion over
the 10-year budgetary window of 2013 through 2022. An estimate of the revenue losses of S.
3413’s AMT patch provision—which would extend the AMT patch for 2012 and 2013 (and
extend all of the Bush tax cuts for 2013)—is currently unavailable. However, the revenue loss
estimates of the AMT patch from H.R. 8 (which also extends the patch for two years and all of
the Bush tax cuts for 2013) would result in an estimated $192.73 billion in revenue losses over
the 10-year budgetary window of 2013 through 2022. The revenue losses from extending the
AMT patch for two years (2012 and 2013) included in S. 3521 would reduce revenues by $132.24
billion between 2013 through 2022 assuming the Bush tax cuts expire at the end of 2012.

An Overview of Tax Provisions Expiring in 2012

Policy Debate
The current debate on the AMT patch centers around limiting the number of taxpayers subject to
the AMT, while also minimizing the revenue losses to the federal government from the AMT
patch. The AMT patch, if extended, would reduce the number of taxpayers subject to the AMT by
approximately 26 million.44 Many of these taxpayers are middle- and upper-middle income
taxpayers—especially those with children. However, as previously discussed, the patch is costly
in terms of lost revenue. Congress may choose to consider indexing the AMT for inflation or it
may choose to reform the regular income tax system in such a way that the AMT no longer
exists.45
Payroll Tax Cut
Current Law
The payroll tax cut—initially enacted for 2011 by P.L. 111-312 and extended for 2012 by P.L.
112-78 and P.L. 112-96—reduced the employee’s share of Social Security payroll taxes.46
Specifically, the payroll tax cut reduced the employee’s share47 of Social Security taxes from
6.2% to 4.2% for employees and from 12.4% to 10.4% for the self-employed on the first
$110,100 of wages in 2012.48
Legislation Considered to Extend the Payroll Tax Cut
There is currently no legislation that has been considered by the House and Senate to extend the
payroll tax cut after it expires at the end of 2012.
Budgetary Cost
The total cost of the payroll tax cut for 2011 and 2012 has been estimated to be $225.7 billion for
the 2011-2022 budgetary window.49 Of this total cost, the 2011 payroll tax cut reduced revenues

44 The Tax Policy Center estimates that over 31 million taxpayers will owe the AMT in 2012 without an AMT “patch.”
For more information, see http://www.taxpolicycenter.org/taxtopics/AMT.cfm.
45 Some experts have suggested eliminating the regular income tax and simply making the AMT the only income tax.
According to certain analysts, it would have been less costly in 2009 to eliminate the regular income tax than the AMT.

Institute, Discussion Paper No. 25, August 2005, http://www.taxpolicycenter.org/UploadedPDF/

47 The payroll tax cut did not reduce employer’s share of payroll taxes. The social security payroll tax (prior to the
payroll tax reduction) is 12.4%. Statutorily, employer’s pay half of the tax (6.2%) and employees pay the other half
(6.2%), although many economists believe that workers end up bearing the entire cost of the tax in reduced wages.

by $111.7 billion between 2011 and 2020, and the 2012 payroll tax cut reduced revenues by
$114.0 billion between 2012 and 2022.50
Policy Debate
The payroll tax cut was intended to provide an economic stimulus by increasing workers’ take-
home pay. This tax cut benefits virtually all working Americans, but research indicates that this
policy may not be as targeted or cost-effective a stimulus as other tax policies or direct-spending
programs. Approximately 159 million workers will be eligible for the payroll tax cut in 2012,
which on average will equal approximately $717 per worker.51 However, the actual value will
depend on the taxpayer’s wages, with those making $20,000 receiving an additional $400 in take-
home pay, and those making $110,100 or more (the Social Security wage cap in 2012) receiving a
maximum increase of $2,202 in take-home pay.
Because the payroll tax cut is not targeted to those facing the greatest fiscal constraints (it is
available to 94%52 of wage earners irrespective of income level), a portion of it may be saved
instead of spent, limiting the stimulative impact of this policy.53 The Congressional Budget
Office—which assumed that the majority of the increase in disposable income would be saved or
used to pay down debt rather than spent on goods and services—estimated that a temporary
reduction of payroll taxes would raise output cumulatively in the next two years by between 10
and 90 cents per dollar of total budgetary cost and would increase employment by between one
and nine jobs per million dollars of budgetary cost.54 According to CBO, the short-term stimulus
impact of the payroll tax cut is lower than increasing aid to unemployed or providing additional
refundable tax credits to low- and middle-income households (but on par with extending the
AMT-patch). However, the same report indicated that the payroll tax cut was more stimulative in
the short term than extending the Bush tax cuts. In addition, at the end of 2011 when the payroll
tax cut was originally scheduled to expire, several economic reports indicated that its expiration
could hamper economic growth.55 Finally, policymakers may be concerned that this temporary
provision could become a provision which is routinely extended. They may be concerned about
the budgetary impact of these routine extensions. Or they may have concerns that routine
extensions will negatively impact the Social Security trust fund, although the current payroll tax
cut requires that the Social Security trust funds be “made whole” by a transfer of general revenue.

related to individuals, businesses, charitable giving, energy, community development, or disaster
relief. Table 2 provides a list of provisions that expired in 2011 or are scheduled to expire at the
end of 2012, including information on the estimated 10-year cost of extending the provision for
one year. In addition, the table includes information as to whether S. 3521 would extend the
provision (this bill extends all expiring provisions through the end of 2013). Importantly, while
most of the provisions that expired in 2011 or are scheduled to expire at the end of 2012 have
been routinely extended on a short-term basis, and are hence commonly referred to as “tax
extenders,” there are a variety of expiring provisions that have not been previously extended.
Both traditional “tax extenders” and these new expiring provisions are included in Table 2.
Individual
Several temporary tax provisions affecting individuals either expired at the end of 2011 or are
scheduled to expire at the end of 2012. Of these, the largest in terms of estimated revenue losses
include the deduction for state and local sales taxes;57 the refundability of the credit for prior
minimum tax liability; the above-the-line deduction for qualified tuition and related expenses;58
the deduction of mortgage insurance premiums as qualified interest; the expansion of the
adoption credit and adoption assistance programs;59 the above-the-line deduction for certain
expenses of elementary and secondary school teachers;60 and the parity in the tax treatment of
employer-provided transit benefits to parking benefits.
Business
Several temporary tax provisions affecting businesses either expired at the end of 2011 or are
scheduled to expire at the end of 2012. Of these, the largest in terms of estimated revenue losses
include bonus depreciation in 2011 and 2012, whereby a 100% bonus depreciation allowance is in
effect through the end of 2011, set to decrease to 50% for 2012 and expire after December 31,

56 Some of the provisions expire after 2012. A complete list can be found in Joint Committee on Taxation, List of
Expiring Federal Tax Provisions, January 13, 2012, JCX-1-12. In addition, for an overview of laws which have
extended individual provisions, see Table in CRS Report R42105, Tax Provisions Expiring in 2011 and “Tax

An Overview of Tax Provisions Expiring in 2012

2012; the research and experimentation credit;61 the exception under Subpart F for active
financing income earned by banking, financing, and insurance business operations abroad;62 the
enhanced cost-recovery for qualified leasehold, restaurant, and retail improvements; and the
enhanced expensing allowances which allow businesses to expense $500,000 for investment in
qualified investment in 2011, $125,000 in 2012, and $25,000 thereafter.63
Charitable
Several temporary provisions designed to incentivize charitable giving64 expired at the end of
2011. Of these, the largest in terms of estimated revenue losses include tax-free distributions from
IRAs for the purposes of charitable donations; enhanced charitable deductions for corporate
contributions of computer equipment for education purposes; and enhanced charitable deductions
for contributions of food inventory.
Energy
Several temporary provisions affecting the energy sector, including alternative energy, expired at
the end of 2011 or are scheduled to expire at the end of 2012. Of these, the largest in terms of
estimated revenue losses include incentives for alcohol fuels (primarily ethanol); incentives for
biodiesel and renewable diesel;65 the Section 1603 grants-in-lieu of tax credit;66 the placed-in-
service date for the production tax credit for wind; and the credit for nonbusiness energy property
(sometimes referred to as the “25C credit”).67
Community Development
Several provisions to promote community development expired at the end of 2011. These include
qualified zone academy bonds, which are available to state and local governments for elementary
and secondary school renovation, equipment, teacher training, and course materials; the new
markets tax credit (NMTC), which is designed to promote investment in low-income and
impoverished communities;68 and tax incentives to encourage economic activity in empowerment
zones,24 the District of Columbia (DC), and in the American Samoa.69

An Overview of Tax Provisions Expiring in 2012

Disaster Relief Provisions
A number of disaster-related tax provisions expired at the end of 2011 or are scheduled to expire
at the end of 2012. They include provisions designed to help redevelopment of the New York
Liberty Zone and the Gulf Opportunity (GO) Zone,70 as well as provisions to provide relief
following the Midwestern storms and Hurricane Ike in 2008.
Legislation Considered to Extend Certain Expiring Provisions and
Tax Extenders
The Senate may consider S. 3521, the Family and Business Tax Cut Act of 2012, which extends
some, though not all, of the expiring provisions detailed in Table 2 through the end of 2013.
Table 2 includes information on whether a particular provision is extended by S. 3521 and the 10-
year (2013-2022) revenue loss estimates associated with extending the provision through the end
of 2013.71
Budgetary Cost
The revenue losses from extending the tax extender provisions depends on which provisions are
extended and the duration of the extension. The Joint Committee on Taxation (JCT) estimated
that the cost of extending temporary provisions that expired in 2011 through the end of 2012 was
$42.92 billion dollars over the 2012-2021 budgetary window.72 By contrast, the JCT estimated
that the cost of extending certain expiring provisions through the end of 2013 was $205.06 billion
over the 10-year period of 2013 through 2022.73The U.S. Treasury estimated that extending
certain temporary provisions that expired in 2011 and 2012 through the end of 2013 was $26
billion over the 2013-2022 budgetary window.74 CBO estimated that the revenue losses from
extending temporary provisions75 for a longer period than one or two years—through 2022—
would reduce revenues by $839 billion over the 2013-2022 budgetary window.76 The debt service
associated with financing these extensions was estimated to be $173 billion over the same period.

An Overview of Tax Provisions Expiring in 2012

Policy Debate
Congress may enact tax provisions on a temporary basis for a variety of reasons, including to
provide short-term stimulus (e.g., the enhanced expensing provisions), to provide short-term
disaster relief, or to encourage Congress to re-evaluate the efficacy of these provisions on a
routine basis. The budgetary cost of a short-term extension is less than the cost of a longer-term
extension, which some analysts contend is a major reason that these provisions are extended on a
short-term basis.77 At a recent Senate Finance Committee hearing on tax extenders, Dr. Roseanne
Altshuler stated
…temporary tax legislation may simply (but sadly) be the result of Congress playing a
budget game. The Congressional Budget Office (CBO) must project the revenue baseline
using current law. This means that the CBO must assume that temporary provisions expire as
scheduled. If, as past history would strongly suggest, temporary provisions are never allowed
to lapse, then they effectively become permanent feature of the code that are not accounted
for in the revenue baseline. Since almost all extenders involve tax cuts, the assumption they
will be terminated tends to make the CBO project a healthier revenue baseline than is likely
to occur.78
But while the temporary nature of these provisions and the resulting budgetary score may make
them more politically palatable, some policymakers contend that the temporary nature of these
provisions, and the uncertainty about whether they will be extended, limits their ability to achieve
their policy objectives.79

Dr. Rosanne Altshuler, January 31, 2012, http://finance.senate.gov/hearings/hearing/?id=b1604e2e-5056-a032-52ff-
dd661f9280f6.
79 For example, Senator Max Baucus, chairman of the Senate Finance Committee has stated that “Many construction
projects, for example, take at least five years to plan, finance and build. When Congress passes an investment tax credit
for only one year, there’s no guarantee for a town, city or developer to move forward with a five-year project.”
http://finance.senate.gov/imo/media/doc/01312012_Baucus_Says_Tax_Rules_Should_Help_Businesses_with_Long-
Term_Plans_Grow,_Not_Hinder_Them[1]1.pdf. In addition, Senator Hatch, ranking Member of the Senate Finance
Committee has said that “Even those extenders that are sound tax policy lose much of their power due to their
temporary character.” http://finance.senate.gov/newsroom/ranking/release/?id=4042ffa9-9861-431a-8ea8-

than once. However, this table also includes tax provisions that are expiring that have not previously been extended. For provisions for which a cost estimate of a 1-year
extension is not available, recent revenue loss estimates are included in the footnotes, along with the Joint Committee on Taxation (JCT) source. ”na” means a revenue loss
estimate is not available. In addition to extending certain expiring provisions, S. 3521 extends the low income housing tax credit’s temporary minimum applicable
percentage of 9% with respect to which credit allocations are made before January 1, 2014. The bill also expands the section 30D credit to include electric motorcycles.

i.
One-year extension for 2011, with budgetary cost over the 2011-2020 budgetary window (JCX-48-10).
j.
A previous extension of the combined costs of the increase in first-year depreciation to 100% and extending the 50% additional first-year depreciation for property

o. This provision was scheduled to expire September 30, 2012.
p. A previous extension of this provision resulted in an estimated $45 million in revenue losses over the 2009-2018 budgetary window (JCX-78-08).
q. A previous extension of this provision for a variety of renewable technologies (i.e., not exclusively wind) resulted in $13.14 billion in revenue losses over the 2009-

u. At enactment, tax exempt bond financing for areas damaged by the 2008 Midwestern storms and low-income housing tax relief for areas damaged by Hurricane Ike
was estimated to result in $638 mil ion in revenue losses over the 2009-2019 budgetary window (JCX-78-08).

w. The placed in service date for the PTC for wind was scheduled to expire at the end of 2012, while the placed in service date for the PTC for other renewable
technologies were general y scheduled to expire at the end of 2013. Prior to S. 3521, extensions of the PTC extended the placed-in-service date for eligible properties.
Hence if a wind facility was operating prior to the expiration date, they would be eligible for the credit. The extension of the PTC for wind included a provision that
modified the expiration date for all renewable technologies (including wind) such that qualified facilities wil be eligible for the PTC (or the investment tax credit in lieu
of the production tax credit, if the construction—as opposed to the placed in service date—begins prior to the end of 2013.
x. This provision raises $12 million between the 10-year budgetary window of 2013 through 2022.
y. S. 3521 expands qualified cel ulosic biofuel production to include algae-based fuel.
z. A previous extension of this provision was estimated to result in $362 million in revenue losses over the 2009-2018 budgetary window (JCX-78-08).

An Overview of Tax Provisions Expiring in 2012

Concluding Remarks
As Congress decides whether to extend some or all of these expiring tax provisions, it may
consider several options. It may choose to extend all expiring tax provisions. CBO estimated that
extending these provisions through 2022 (except for the payroll tax cut, which CBO assumes
expires as scheduled at the end of 2012) would reduce revenues by $5.4 trillion between 2013 and
2022. Specifically, over this 10-year budgetary window, extending the Bush tax cuts and
extending the AMT patch would reduce revenues by $4.6 trillion, while extending other expiring
provisions and “tax extenders” would reduce revenues by $839 billion. The cost of extending the
payroll tax cut for one year (2012) was estimated to be $114 billion over the 2012-2022
budgetary window. The extension of these provisions, if they are not offset, would increase the
10-year cumulative (2013-2022) deficit from $3.07 trillion to $9.44 trillion (including $963
billion in debt service between 2013 and 2022). This would result in projected deficits as a
percentage of GDP (a measure of deficits in proportion to the economy) rising from 1.5% to
4.7%, a figure many economists view as unsustainable.80 The deficit would be even higher if the
payroll tax cut is extended again and is not offset.
Congress may instead choose to allow all temporary provisions to expire. According to CBO, this
will result in a considerable rise in revenue that will have a significant effect on reducing the
projected future deficit.81 However, some economists warn that the scheduled expiration of these
temporary provisions, which would occur simultaneously with the scheduled expiration of
emergency unemployment insurance benefits and scheduled budget cuts under the Budget
Control Act, would reduce real GDP growth.82
Finally, Congress may choose to balance the objectives of deficit reduction and economic
assistance by extending certain provisions it determines are effective, while letting others expire.
Alternatively, Congress may pursue this objective by considering a fundamental reform of the tax
code.83

80 A budget deficit can be “sustainable” if deficits are small enough so that the accumulation of annual deficits—the
debt—does not grow faster than GDP. Experts differ on what is the exact size of a sustainable budget deficit, but they
generally cite figures below 3% of GDP. Prior CRS analysis estimated that annual budget deficits would need to be no
larger than 2.5% to 3.0% of GDP over the next 10 years in order to stabilize the debt as a share of GDP at its projected
2011 level (69% of GDP). For more information, see CRS Report R41778, Reducing the Budget Deficit: Policy Issues,
