Tax Provisions that Expired in 2014 (“Tax Extenders”)  
 
Summary 
In the past, Congress has regularly acted to extend expired or expiring temporary tax provisions. 
Collectively, these temporary tax provisions are often referred to as “tax extenders.” Fifty-two 
temporary tax provisions expired at the end of 2014. The 114th Congress may choose to further 
extend some or all of these provisions. This report provides a broad overview of the tax 
extenders. 
The Tax Increase Prevention Act of 2014 (P.L. 113-295), signed into law on December 19, 2014, 
made tax provisions that had expired at the end of 2013 available to taxpayers for the 2014 tax 
year. The law extended most (but not all) provisions that had expired at the end of 2013. Further, 
most of the provisions in P.L. 113-295 had been included in previous “tax extender” packages.  
Other legislation considered in the 113th Congress would have also extended expired tax 
provisions. The Expiring Provisions Improvement Reform and Efficiency (EXPIRE) Act (S. 
2260) would have extended expired tax provisions for two years. The Jobs for America Act (H.R. 
4), which passed the House on September 18, 2014, would have permanently extended certain 
expired tax provisions. Several expired charitable-related provisions would have been made 
permanent as part of the America Gives More Act of 2014 (H.R. 4719), which passed the House 
on July 17, 2014. Several of the proposals to permanently extend certain expired provisions in the 
113th Congress have also been considered in the 114th Congress. 
The President’s FY2016 budget identifies several expiring provisions that should be permanently 
extended (and in some cases substantially modified), including the research and experimentation 
(R&E) tax credit, enhanced expensing for small businesses, the renewable energy production tax 
credit (PTC), and the new markets tax credit (NMTC). Several other expired provisions would be 
temporarily extended. The President’s FY2016 budget also assumes that the American 
Opportunity Tax Credit (AOTC), the earned income tax credit (EITC) expansions, and the child 
tax credit (CTC) expansions, which were extended through 2017 as part of the American 
Taxpayer Relief Act (ATRA), are made permanent.  
There are several reasons why Congress may choose to enact tax provisions on a temporary basis. 
Enacting provisions on a temporary basis provides legislators with an opportunity to evaluate the 
effectiveness of tax policies prior to expiration or extension. Temporary tax provisions may also 
be used to provide temporary economic stimulus or disaster relief. Congress may also choose to 
enact tax provisions on a temporary rather than permanent basis due to budgetary considerations, 
as the foregone revenue from a temporary provision will generally be less than if it was 
permanent.  
The provisions that expired at the end of 2014 are diverse in purpose, including provisions for 
individuals, businesses, the charitable sector, and energy-related activities. Among the individual 
provisions that expired are deductions for teachers’ out-of-pocket expenses, state and local sales 
taxes, qualified tuition and related expenses, and mortgage insurance premiums. On the business 
side, under current law, the research and development (R&D) tax credit, the work opportunity tax 
credit (WOTC), the active financing exceptions under Subpart F, the new markets tax credit, and 
increased expensing and bonus depreciation allowances will not be available for taxpayers after 
2014. Expired charitable provisions include the enhanced deduction for contributions of food 
inventory and provisions allowing for tax-free distributions from retirement accounts for 
charitable purposes. The renewable energy production tax credit (PTC) expired at the end of 
2014, along with a number of other incentives for energy efficiency and renewable and alternative 
fuels.

Tax Provisions that Expired in 2014 (“Tax Extenders”)  
 
Introduction 
There are dozens of temporary tax provisions in the Internal Revenue Code (IRC), many of which 
expired at the end of 2014. Recent legislation extended certain expiring provisions. The American 
Taxpayer Relief Act (ATRA; P.L. 112-240), signed into law on January 2, 2013, reduced tax 
policy uncertainty by permanently extending most of the tax cuts first enacted in 2001 and 2003 
and permanently indexing the alternative minimum tax (AMT) for inflation.1 ATRA, however, did 
not eliminate uncertainty in the tax code. Under ATRA, a number of provisions that had been 
allowed to expire at the end of 2011 or 2012 were temporarily extended through 2013.2 Most of 
the provisions that expired at the end of 2013 were retroactively extended for one year, through 
2014, in the Tax Increase Prevention Act of 2014 (P.L. 113-295).  
Collectively, temporary tax provisions that are regularly extended by Congress rather than being 
allowed to expire as scheduled are often referred to as “tax extenders.” Many of these “tax 
extender” provisions have been temporarily extended multiple times. The research tax credit, for 
example, has been extended 16 times since being enacted in 1981. Most of the temporary tax 
provisions that expired at the end of 2014 were previously extended more than once.  
The Tax Increase Prevention Act of 2014, passed late in the 113th Congress, extended expiring tax 
provisions for one year, retroactively through 2014. Other legislation considered in the 113th 
Congress proposed a two-year extension—the Expiring Provisions Improvement Reform and 
Efficiency (EXPIRE) Act (S. 2260). Legislation was also considered that would have made 
certain expiring provisions permanent—see, for example, the Jobs for America Act (H.R. 4) and 
the America Gives More Act of 2014 (H.R. 4719). Tax reform legislation introduced in the 113th 
Congress, the Tax Reform Act of 2014 (H.R. 1), proposed to make permanent certain provisions 
that are currently part of the tax extenders, including the research and experimentation (R&D) tax 
credit and increased expensing allowances for certain businesses allowed under Internal Revenue 
Code (IRC) Section 179.3 The 114th Congress has also considered proposals that would make 
certain expired provisions permanent.  
The President’s FY2016 budget also proposes to permanently extend or modify certain expired 
provisions and temporarily extend others.4 The President’s budget assumes that the American 
opportunity tax credit (AOTC), the earned income tax credit (EITC) expansions, and the child tax 
credit (CTC) expansions, which were extended through 2017 as part of ATRA, are made 
permanent.  
Temporary tax provisions that expired at the end of 2014 will not necessarily be unavailable to 
taxpayers in 2015. In recent years, Congress has chosen to retroactively extend expired tax

2 Provisions that had been allowed to expire at the end of 2011 were extended retroactively. In addition to the “tax 
extenders” discussed in this report, several provisions first enacted as part of the American Recovery and Reinvestment 
Act (ARRA; P.L. 111-5) were temporarily extended in ATRA.

provisions. The Tax Increase Prevention Act of 2014, signed into law on December 19, 2014,

The Concept of “Tax Extenders” 
The tax code presently contains dozens of temporary tax provisions. In the past, legislation to 
extend some set of these expiring provisions has been referred to by some as the “tax extender” 
package. While there is no formal definition of a “tax extender,” the term has regularly been used 
to refer to the package of expiring tax provisions temporarily extended by Congress. Oftentimes, 
these expiring provisions are temporarily extended for a short period of time (e.g., one or two 
years). Over time, as new temporary provisions have been routinely extended and hence added to 
this package, the number of provisions that might be considered “tax extenders” has grown.5  
Evaluating Expiring Tax Provisions 
There are various reasons Congress may choose to enact temporary (as opposed to permanent) tax 
provisions. Enacting provisions on a temporary basis, in theory, would provide Congress with an 
opportunity to evaluate the effectiveness of specific provisions before providing further 
extension. Temporary tax provisions may also be used to provide relief during times of economic 
weakness or following a natural disaster. Congress may also choose to enact temporary provisions 
for budgetary reasons. Examining the reason why a certain provision is temporary rather than 
permanent may be part of evaluating whether a provision should be extended. 
Reasons for Temporary Tax Provisions 
There are several reasons why Congress may choose to enact tax provisions on a temporary basis. 
Enacting provisions on a temporary basis may provide an opportunity to evaluate effectiveness 
before expiration or extension. However, this rationale for enacting temporary tax provisions is 
undermined if expiring provisions are regularly extended without systematic review, as is the case 
                                                 
5 For a history of the tax extenders, see U.S. Congress, Senate Committee on Rules and Administration, The Tax 
Extenders: How Congressional Rules and Outside Interests Shape Policy, committee print, prepared by Congressional 
Research Service, 113th Cong., 2nd sess., December 2014, S. Prt. 113-30, pp. 441-456, available at http://www.gpo.gov/

in practice. In 2012 testimony before the Senate Committee on Finance, Dr. Rosanne Altshuler 
noted that 
an expiration date can be seen as a mechanism to force policymakers to consider the costs 
and benefits of the special tax treatment and possible changes to increase the 
effectiveness of the policy. This reasoning is compelling in theory, but has been an 
absolute failure in practice as no real systematic review ever occurs. Instead of subjecting 
each provision to careful analysis of whether its benefits outweigh its costs, the extenders 
are traditionally considered and passed in their entirety as a package of unrelated 
temporary tax benefits.6 
While most expiring tax provisions have been extended in recent years, there have been some 
exceptions. For example, tax incentives for alcohol fuels (e.g., ethanol), which can be traced back 
to policies first enacted in 1978, were not extended beyond 2011. The Government Accountability 
Office (GAO) had previously found that with the renewable fuel standard (RFS) mandate, tax 
credits for ethanol were duplicative and did not increase consumption.7 Congress may choose not 
to extend certain provisions if an evaluation determines that the benefits provided by the 
provision do not exceed the cost (in terms of foregone tax revenue). 
Tax policy may also be used to address temporary circumstances in the form of economic 
stimulus or disaster relief. Economic stimulus measures might include bonus depreciation or 
generous expensing allowances.8 Disaster relief policies might include enhanced casualty loss 
deductions or additional net operating loss carrybacks.9 Other recent examples of temporary 
provisions that have been enacted to address special economic circumstances include the 
exclusion of mortgage forgiveness from taxable income during the recent housing crisis,10 the 
payroll tax cut,11 and the grants in lieu of tax credits to compensate for weak tax-equity markets 
during the economic downturn (the Section 1603 grants).12 It has been argued that provisions that 
were enacted to address a temporary situation should be allowed to expire once the situation is 
resolved.13

Congress may also choose to enact tax policies on a temporary basis for budgetary reasons. If 
policy makers decide that legislation that reduces revenues must be paid for, it is easier to find 
resources to offset short-term extensions rather than long-term or permanent extensions.14 
Additionally, by definition the Congressional Budget Office (CBO) assumes under the current 
law baseline that temporary tax cuts expire as scheduled. Thus, the current law baseline does not 
assume that temporary tax provisions are regularly extended. Hence, if temporary expiring tax 
provisions are routinely extended in practice, the CBO current law baseline would tend to 
overstate projected revenues, making the long-term revenue outlook stronger. In other words, by 
making tax provisions temporary rather than permanent, these provisions have a smaller effect on 
the long-term fiscal outlook.15  
Extenders as Tax Benefits16 
Temporary tax benefits are a form of federal subsidy that treats eligible activities favorably 
compared to others, and channels economic resources into qualified uses. Extenders influence 
how economic actors behave and how the economy’s resources are employed. Like all tax 
benefits, extenders can be evaluated by looking at the impact on economic efficiency, equity, and 
simplicity.17 Temporary tax provisions may be efficient and effective in accomplishing their 
intended purpose, though not equitable. Alternatively, an extender may be equitable but not 
efficient. Policy makers may have to choose the economic objectives that matter most.  
Economic Efficiency 
Extenders often provide subsidies to encourage more of an activity than would otherwise be 
undertaken. According to economic theory, in most cases an economy best satisfies the wants and 
needs of its participants if markets allocate resources free of distortions from taxes and other 
factors. Market failures, however, may occur in some instances, and economic efficiency may 
actually be improved by tax distortions.18 Thus, the ability of extenders to improve economic 
welfare depends in part on whether or not the extender is remedying a market failure. According 
to theory, a tax extender reduces economic efficiency if it is not addressing a specific market 
failure.

18 Market failure occurs when the marginal benefit of an action does not equal the marginal cost. For example, 
polluting forms of energy production cause social costs that are not taken into account by the producer; hence, there is 
an argument for taxing this type of energy or, alternatively, subsidizing less-polluting firms.

An extender is also considered relatively effective if it stimulates the desired activity better than a 
direct subsidy. Direct spending programs, however, can often be more successful at targeting 
resources than indirect subsidies made through the tax system such as tax extenders.19 
Equity  
A tax is considered to be fair when it contributes to a socially desirable distribution of the tax 
burden. Tax benefits such as the extenders can result in individuals with similar incomes and 
expenses paying differing amounts of tax, depending on whether they engage in tax-subsidized 
activities. This differential treatment is a deviation from the standard of horizontal equity, which 
requires that people in equal positions should be treated equally. 
Another component of fairness in taxation is vertical equity, which requires that tax burdens be 
distributed fairly among people with different abilities to pay. Most extenders are considered 
inequitable because they benefit those who have a greater ability to pay taxes. Those individuals 
with relatively less income and thus a reduced ability to pay taxes may not have the same 
opportunity to benefit from extenders as those with higher income. The disproportionate benefit 
of tax expenditures to individuals with higher incomes reduces the progressivity of the tax 
system, which is often viewed as a reduction in equity. 
An example of the effect a tax benefit can have on vertical equity is illustrated by two teachers 
who have both incurred $250 in classroom-related expenses and are eligible to claim the above-
the-line deduction for expenses. Yet the tax benefit to the two differs if they are in different tax 
brackets. A teacher with lower income, who may be in the 15% income tax bracket, receives a 
deduction with a value of $37.50, while another teacher, in the 33% bracket, receives a deduction 
value of $82.50. Thus, the higher-income taxpayer, with presumably greater ability to pay taxes, 
receives a greater benefit than the lower-income taxpayer. 
Simplicity 
Extenders contribute to the complexity of the tax code and raise the cost of administering the tax 
system. Those costs, which can be difficult to isolate and measure, are rarely included in the cost-
benefit analysis of temporary tax provisions. In addition to making the tax code more difficult for 
the government to administer, complexity also increases costs imposed on individual taxpayers. 
With complex incentives, individuals devote more time to tax preparation and are more likely to 
hire paid preparers.  
Tax Provisions that Expired in 2014 
Dozens of temporary tax provisions expired at the end of 2014 (see Table 1). Most of these 
provisions have been extended as part of previous “tax extender” legislation. For the purposes of 
this report, expiring provisions have been classified as belonging to one of four categories: 
individual, business, charitable, or energy. The following sections provide additional details on 
expiring provisions within each category. Table 1 also notes which provisions were extended as 
part of P.L. 113-295, and the 10-year revenue cost of that one-year extension.

Tax Provisions that Expired in 2014 (“Tax Extenders”)  
 
Individual20 
All six of the individual tax extender provisions that expired at the end of 2014 have previously 
been extended as part of tax extenders legislation. The longest-standing individual extender 
provision is the above-the-line deduction for classroom expenses incurred by school teachers. 
This provision was first enacted on a temporary basis in 2002 and has regularly been included in 
tax extender packages. Other individual provisions that have been extended more than once 
include the deduction for state and local sales taxes,21 the above-the-line deduction for tuition and 
related expenses,22 the deduction for mortgage insurance premiums,23 and the parity for the 
exclusion of employer-provided mass transit and parking benefits. 
Business24 
All of the business provisions that expired at the end of 2014 have been extended at least once, 
most more than once. Long-standing provisions that are scheduled for expiration include the 
research tax credit,25 the rum excise tax cover-over,26 the Work Opportunity Tax Credit,27 the 
Qualified Zone Academy Bond (QZAB) allocation limitation,28 and the active financing 
exception under Subpart F.29 The New Markets Tax Credit, first enacted in 2000 to promote 
investment in low-income communities, also expired at the end of 2014.30 Bonus depreciation and 
enhanced expensing allowances, which are often viewed as economic stimulus measures, also 
expired at the end of 2014.31

Tax Provisions that Expired in 2014 (“Tax Extenders”)  
 
Charitable32  
The four charitable provisions that expired at the end of 2014 have previously been extended 
multiple times. Provisions providing an enhanced deduction for noncorporate businesses donating 
food inventory were first enacted in response to Hurricane Katrina in 2005.33 The remaining 
charitable provisions set to expire were first enacted as part of the Pension Protection Act of 2006 
(P.L. 109-280).34  
Energy35 
The longest-standing energy-related provision that expired at the end of 2013 is the renewable 
energy production tax credit (PTC).36 Several of the temporary energy-related tax provisions that 
expired at the end of 2014 were first enacted as part of the Energy Policy Act of 2005 (EPACT05; 
P.L. 109-58). These include the credit for construction of energy efficient new homes, the 
deduction for energy efficient commercial buildings, and the credit for nonbusiness energy 
property (also known as the tax credit for energy efficiency improvements for existing homes).37 
Certain tax incentives for alternative technology vehicles and alternative fuel vehicle refueling 
property were also first included in EPACT05.  
The alternative motor vehicle credit for qualified fuel cell vehicles also expired at the end of 
2014. This provision was introduced as part of EPACT05, and set to expire December 31, 2014, 
when first introduced. EPACT05 incentives for other alternative motor vehicles—including 
hybrids, alternative fuel, and advanced lean-burn technology vehicles—expired at earlier dates. 
                                                 
32 The Tax Increase Prevention Act of 2014 contained separate subtitles for individual, business, and energy extenders, 
but not for charitable extenders. Charitable extenders have been separately identified for the purposes of this report, as 
there was considerable debate regarding permanent extension of these provisions in the 113th and 114th Congresses 
(discussed below). For more information, see CRS Report R43517, Recently Expired Charitable Tax Provisions (“Tax 
Extenders”): In Brief, by Jane G. Gravelle and Molly F. Sherlock.

36 For more information, see CRS Report R43453, The Renewable Electricity Production Tax Credit: In Brief, by 
Molly F. Sherlock. The PTC was first enacted in 2002. When first enacted, the PTC was only available for wind and 
closed-loop biomass technologies. Over time, Congress has expanded the list of qualifying technologies.

Tax Provisions that Expired in 2014 (“Tax Extenders”)  
 
The Cost of Extending Expired and Expiring Tax 
Provisions 
The Congressional Budget Office (CBO) provides estimated costs of extending all tax provisions 
scheduled to expire before 2025 (see Table 2).38 CBO’s estimates can be viewed as the cost of a 
long-term extension. According to CBO’s estimates, over the 2016 to 2025 budget window, 
•  extending all expiring tax provisions would cost $897.9 billion;  
•  extending bonus depreciation would cost $223.6 billion and extending Section 
179 expensing would cost $60.8 billion;39 and 
•  extending expansions to the child tax credit, the earned income tax credit, and the 
American Opportunity Tax Credit currently scheduled to expire at the end of 
2017 would cost $202.8 billion.40  
Of the 70 tax provisions set to expire before the end of 2025, 52 expired at the end of 2014. Thus, 
most of the revenue cost associated with extending expiring provisions is for provisions that have 
already expired.  
Since tax extender provisions are assumed to expire as scheduled by CBO, their extension—even 
if expected by policy makers—is not included in CBO’s current law revenue baseline. As a result, 
CBO’s revenue projections are higher than actual revenue levels that are likely to occur. 
Consequently, projected budget deficits under the current law baseline are smaller than actual 
deficits that are likely to occur.  
The baseline used in the President’s FY2016 budget proposal also makes adjustments for certain 
expiring provisions. Specifically, the President’s FY2016 budget uses a baseline that assumes that 
the American Opportunity Tax Credit (AOTC), expansions to the earned income tax credit 
(EITC), and child tax credit (CTC) are made permanent.  
The cost of providing a short-term extension, as is typical in “tax extenders” legislation, is less 
than the cost of extending expiring provisions through the budget window, as is done by CBO for 
the purposes of constructing the alternative fiscal scenario baseline. The CBO scores presented 
here, some might argue, provide a more accurate measure of the overall or long-term budget 
impact of temporary tax provisions. The Joint Committee on Taxation (JCT) scores 
accompanying extenders legislation reflect the budget impact of the temporary extension relative 
to current law. 
                                                 
38 CBO provides this estimate to calculate their alternative fiscal scenario. CBO’s baseline for spending and revenues 
assumes current law. Thus, revenue levels under CBO’s baseline assume that all tax policies expire as scheduled. The 
alternative fiscal scenario assumes that current policies remain in place (i.e., expiring tax provisions are extended). The 
estimated revenues that would be raised from extending certain provisions might change depending on how provisions 
are stacked (i.e., interaction effects might cause revenue estimates for specific provisions to be higher or lower 
depending on what other provisions are also assumed to have been extended). 
39 For more on bonus depreciation in the context of tax extenders, see CRS Report R43432, Bonus Depreciation: 
Economic and Budgetary Issues, by Jane G. Gravelle.  
40 Extending these provisions would reduce revenues by $44.3 billion between 2016 and 2025, and increase outlays by 
$158.5 billion.

Notes:  
a.  The cost of extending bonus depreciation depends on whether the cost is estimated alongside other tax policy changes, such as an extension in Section 179 
expensing, or in isolation. See Table 3 below for additional cost estimates for extending bonus depreciation. 
b.  Provisions are currently scheduled to expire on December 31, 2017. Includes a lower earned income threshold for the refundable portion of the child tax credit, 
expansions to the earned income tax credit (EITC), and the American Opportunity Tax Credit (AOTC). The figures in this line include both the reduction in tax 
revenues as well as the change in outlays from refundable tax credits. 
c.  Expired provisions include those that expired or are set to expire between December 31, 2014, and December 31, 2025.  
d.  This line includes the cost of extending al  provisions scheduled to expire between 2014 and 2024.  
 
CRS-15 
Tax Provisions that Expired in 2014 (“Tax Extenders”)  
 
If expiring provisions are temporarily extended, the 10-year revenue cost may be less than the 
cost in year 2015, as many of the expired provisions are tax deferrals, or timing provisions. Bonus 
depreciation is one example of a timing provision, where the short-term cost of extension is 
greater than the long-term or budget window cost. The one-year extension of bonus depreciation 
enacted as part of the Taxpayer Relief Act of 2014 (P.L. 113-295) cost an estimated $1.2 billion 
over the 10-year budget window; however, the one-year revenue loss of the same provision in 
2015 was $45.3 billion, with much of the cost recovered in the later years in the budget window. 
As a timing provision, bonus depreciation shifts cost recovery forward, resulting in revenue 
losses in earlier years, with part of that revenue loss recovered in later years. In contrast to a 
temporary extension, making bonus depreciation permanent would cost $223.6 billion over the 
10-year budget window (see Table 2). 
Recent “Tax Extenders” Legislation and Proposals 
During the 113th Congress, the House considered legislation to make permanent certain expired 
tax provisions. In the 114th Congress, the House has again considered a number of the measures 
that passed in the 113th Congress but did not become law.  
114th Congress 
On February 4, 2015, the House Committee on Ways and Means voted to report six bills that 
would permanently extend six separate tax provisions that expired at the end of 2014 (see Table 
3). America’s Small Business Tax Relief Act (H.R. 636) would permanently extend the enhanced 
expensing allowances under Section 179. Two other bills would permanently extend expired S 
corporation provisions—the Permanent S Corporation Built-in Gains Recognition Period Act of 
2015 (H.R. 629) and the Permanent S Corporation Charitable Contribution Act of 2015 (H.R. 
630). The remaining three extenders-related bills would make permanent expired charitable 
provisions—the Fighting Hunger Incentive Act of 2015 (H.R. 644), the Permanent IRA 
Charitable Contribution Act of 2015 (H.R. 637), and the Conservation Easement Incentive Act of 
2015 (H.R. 641). Taken together, these six measures approved by the House Committee on Ways 
and Means would cost $91.5 billion over the 10-year budget window. Of that total cost, 84.3% 
($77.1 billion) is from the proposal to extend the enhanced expensing allowances under Section 
179.  
The President’s FY2016 Budget Proposal 
The President’s FY2016 budget also proposes to permanently extend or modify certain expired 
provisions, and temporarily extend others.41 Provisions that would be permanently extended (and 
in some cases modified) include (1) the increased expensing for certain businesses under Section 
179; (2) the 100% exclusion for qualified small business stock; (3) the research and 
experimentation (R&E) tax credit; (4) certain employment-related credits (the Work Opportunity 
Tax Credit (WOTC) and the Indian employment credit); (5) incentives for renewable electricity 
(the production tax credit (PTC) and investment tax credit (ITC)); (6) the energy-efficient 
commercial building deduction; (7) the New Markets Tax Credit (NMTC); and (8) the enhanced 
deduction for conservation easements. The President’s budget also proposes permanently

Tax Provisions that Expired in 2014 (“Tax Extenders”)  
 
extending the exception under Subpart F for active financing income and the look-through 
treatment of payments between related controlled foreign corporations (CFCs) as part of a 
broader reform to the U.S. international tax system.42  
Provisions that would be temporarily extended in the President’s FY2016 budget proposal include 
(1) the exclusion for cancellation of home mortgage debt (through 2017); (2) the tax credit for 
second generation (cellulosic) biofuel (through 2020, with a phaseout between 2021 and 2024); 
and (3) the tax credit for energy-efficient new homes (through 2025).43  
As noted above, the President’s FY2016 budget assumes that the American opportunity tax credit 
(AOTC), the earned income tax credit (EITC) expansions, and the child tax credit (CTC) 
expansions, which were extended through 2017 as part of ARTA, are made permanent. 
113th Congress 
During the 113th Congress, various bills were considered to either extend or make permanent 
certain tax extender provisions. Ultimately, a one-year “tax extenders” bill was passed and 
enacted late in the year (the Tax Increase Prevention Act of 2014 (P.L. 113-295) was signed into 
law on December 19, 2014). Earlier in the year, the Senate Finance Committee had reported a 
two-year extenders package, the Expiring Provisions Improvement Reform and Efficiency 
(EXPIRE) Act (S. 2260). The EXPIRE Act proposed extending most expiring provisions for two 
years, through 2015.44  
The House also considered legislation to make certain expiring tax provisions permanent during 
the 113th Congress. As noted in Table 3, the House passed legislation that would have made 
permanent nine provisions that are currently part of the tax extenders. Taken together, 
permanently extending these nine provisions would have reduced revenues by an estimated 
$511.4 billion over the 10-year budget window. Six of these nine provisions were included in the 
Jobs for America Act (H.R. 4), which also passed the House in the 113th Congress.45 Three other 
charitable-related provisions were passed as part of the America Gives More Act of 2014 (H.R. 
4719). The Committee on Ways and Means reported legislation during the 113th Congress that 
would have made two additional international-related extender provisions permanent, although 
this legislation was not considered in the full House.

Taxation: Alternatives, by Jane G. Gravelle. 
43 The President’s FY2016 budget also proposed to provide additional funds for or to modify certain other tax 
incentives that are not necessarily expired (although limited allocations may be available). For example, the FY2016 
budget proposes additional funds be provided for tax incentives for carbon dioxide sequestration, advanced energy 
manufacturing tax credits, credits for certain alternative technology vehicles, geographically targeted incentives for 
economic development, and support of tax-favored financing for infrastructure. 
44 In the Senate, the EXPIRE Act became an amendment to H.R. 3474, and a motion to end debate on H.R. 3474 was 
voted down on May 15, 2014. 
45 The Jobs for America Act (H.R. 4) contained the text of a number of previously passed House bills.

Notes: The cost of extension is the estimated revenue loss in the most recent proposal considered by the House. This table includes only legislation that was 
considered either at the committee level or on the House floor. 
a.  The estimated cost of making bonus depreciation permanent, as proposed in H.R. 4718, was $262.9 billion over the 2014 through 2024 budget window. The lower 
revenue cost estimate in H.R. 4 is likely due to interaction effects with other provisions that would be extended in H.R. 4, specifically the increased expensing 
al owances under Section 179. Thus, absent these other provisions, the cost of bonus depreciation would likely be greater.  
 
 
Tax Provisions that Expired in 2014 (“Tax Extenders”)  
 
Tax Provisions that Expired in 2013 that Were Not Extended 
Several provisions that had expired at the end of 2013 were not extended as part of the Tax 
Increase Prevention Act of 2014 (P.L. 113-295). Two of these provisions would have been 
extended in the EXPIRE Act, but were not included in P.L. 113-295: the health coverage tax 
credit and the credit for electric-drive motorcycles and three-wheeled vehicles.  
The health coverage tax credit had been extended as part of past “tax extenders” legislation. The 
health coverage tax credit was first enacted, without an expiration date, as part of the Trade Act of 
2002 (P.L. 107-240). A January 1, 2014, termination date was enacted as part of an act to extend 
the Generalized System of Preferences in 2011 (P.L. 112-40).46 
The other provision that was not extended in P.L. 113-295, but that would have been extended by 
the EXPIRE Act, was the credit for electric-drive motorcycles and three-wheeled vehicles. In 
recent years, a number of incentives have been available for various alternative technology 
vehicles. There are currently incentives available for plug-in electric vehicles. Incentives for most 
other alternative technology vehicles have expired.47 
Two other energy-related provisions were not extended past their January 1, 2014, termination 
date: the placed-in-service date for partial expensing of certain refinery property and the credit for 
energy efficient appliances. The EXPIRE Act did not propose extending either of these 
provisions.  
Two disaster-related provisions that expired at the end of 2013—one that provided tax-exempt 
bond financing authority for facilities in the New York Liberty Zone and another related to the 
replacement period for nonrecognition of gain for areas damaged by the 2008 Midwestern 
storms—were not extended in P.L. 113-295. The EXPIRE Act also did not include an extension 
for these disaster-related provisions.
