The Impact of Major Legislation on Budget Deficits: 2001 to 2009 
 
Summary 
After recording a fiscal year (FY) 2000 federal budget surplus of $236.2 billion, the 
Congressional Budget Office (CBO) in January 2001 projected continued surpluses throughout 
the decade. However, enactment of major legislation during the 107th to 111th Congresses, in 
combination with changing economic conditions, altered the federal budget outlook for the 
decade dramatically. In FY2002, the budget recorded a deficit for the first time since 1997, and 
the federal government has run a deficit in each subsequent year. 
This report examines to what extent major legislative changes from 2001 to 2009 caused the 
budget to move from surplus to deficit. Legislative actions taken in 2009 increased the FY2009 
deficit by $509 billion, whereas legislative actions taken between 2001 and 2008 increased the 
FY2009 deficit by $903 billion. Furthermore, legislative changes have cumulatively increased 
federal budget deficits over FY2001 to FY2009 by $5.4 trillion. 
Several major tax laws passed by Congress reduced federal government revenues, including the 
Economic Growth and Tax Relief Reconciliation Act of 2001 (P.L. 107-16), the Jobs and Growth 
Tax Relief Reconciliation Act of 2003 (P.L. 108-27), and the Working Families Tax Relief Act of 
2004 (P.L. 108-311). On an aggregated basis, estimates by CBO and the Joint Committee on 
Taxation (JCT) at the time of legislative enactment placed the total anticipated cost for these three 
laws at $1.76 trillion for FY2001 to FY2011. 
The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (P.L. 108-173) 
established a new Medicare Part D prescription drug benefit, which CBO originally projected 
would cost $552.2 billion over 10 years. However, the Boards of Trustees for Medicare estimated 
in May 2009 that Part D expenditures would total $381.3 billion for this same period. 
Funding for “Global War on Terror” operations has been provided primarily through emergency 
supplemental appropriations law. For FY2001 to FY2009, Congress approved legislation 
appropriating about $943.8 billion for military operations in Iraq and Afghanistan, with $887.8 
billion of this amount allocated to the Department of Defense. 
On September 6, 2008, the Federal Housing Finance Agency exercised authority provided under 
the Housing and Economic Recovery Act of 2008 (P.L. 110-289) to place Fannie Mae and 
Freddie Mac into conservatorship. In August 2009, CBO estimated net subsidy costs related to 
Fannie Mae and Freddie Mac at $291 billion for FY2009. The Emergency Economic Stabilization 
Act of 2008 (Division A of P.L. 110-343) established the Troubled Asset Relief Program (TARP). 
In January 2010, CBO projected TARP would increase budget deficits by $99 billion over the 
complete duration of the program. 
In response to significant weakness in the U.S. economy, the Economic Stimulus Act of 2008 
(P.L. 110-185) provided a refundable individual income tax rebate. JCT estimated in February 
2008 that P.L. 110-185 would increase federal budget deficits by approximately $124.5 billion for 
FY2008 to FY2018. To provide additional economic stimulus, Congress enacted the American 
Recovery and Reinvestment Act of 2009 (P.L. 111-5) on February 17, 2009. In January 2010 
CBO estimated that P.L. 111-5 will increase federal budget deficits by $862 billion over 10 years.

The Impact of Major Legislation on Budget Deficits: 2001 to 2009 
 
he annual federal budget deficit is the amount by which federal government outlays 
exceed revenues for a given fiscal year (FY), with surpluses generated when revenues 
T exceed outlays.1 Budget deficits or surpluses are often used to gauge national fiscal health, 
as budget balances over time determine levels of federal debt held by the public, and 
corresponding net interest payments required for debt service.2 During an economic downturn, 
budget deficits could be viewed as effective fiscal policy, with lawmakers enacting tax cuts and 
increasing federal spending to simulate economic activity. However, recurring deficits can 
generate serious longer-term macroeconomic consequences, including a reduction in national 
saving and investment, and a decreased rate of capital accumulation.3 This report examines to 
what extent major legislative changes from 2001 to 2009 caused the budget to move from surplus 
to deficit. 
Federal Budget Deficits: 2001 to 2009 
After recording a FY2000 federal budget surplus of $236.2 billion, the Congressional Budget 
Office (CBO) in January 2001 projected continued surpluses throughout the decade, with a $710 
billion positive budget balance expected for FY2009.4 However, enactment of major legislation 
during the past decade, in combination with changing economic conditions, altered the long-term 
federal budget outlook dramatically. In FY2002, the budget recorded a deficit for the first time 
since 1997, and the federal government has run a deficit in each subsequent year. Most recently, 
the FY2009 deficit was $1.4 trillion, a $2.1 trillion negative change in budget balance from the 
$710 billion FY2009 surplus projected by CBO in 2001.5 
The broad reason the budget moved from surplus to deficit is because Congress chose an overall 
level of spending that exceeded chosen revenue levels. However, the budget is the sum of its 
parts, so no single spending or tax decision can be taken in isolation and be said to have “caused” 
the deficit in an absolute sense. 
Furthermore, some determinants of spending and revenues are not directly controlled by 
Congress. When economic conditions change, spending and revenues automatically change 
without any change in law. For example, when economic growth slows, the growth of taxable 
income slows, so that less revenue is collected at a given tax rate than previously. Likewise, if a 
slowdown in economic growth causes unemployment to rise, spending on unemployment 
insurance and other means-tested mandatory spending programs will also increase without any 
change in law. Economists refer to these changes as “automatic stabilizers” because they 
automatically cause the deficit to rise when the economy slows, thereby helping to offset the 
                                                
1 The federal budget includes both on-budget and off-budget components. The Balanced Budget and Emergency Deficit 
Control Act of 1985 (P.L. 99-177) moved revenues and outlays of the two Social Security Trust Funds off-budget, and 
the Postal Service was moved off-budget by the Omnibus Reconciliation Act of 1989. All annual federal budgetary 
figures presented in this report use combined on-budget and off-budget totals. For more information, see CRS Report 
RS20350, Off-Budget Status of Federal Entities: Background and Current Proposals, by Bill Heniff Jr.

slowdown in growth because of the deficit’s expansionary effects on aggregate spending. It 
should also be noted that when economic growth is strong, the opposite effects occur, with levels 
of taxable income increasing and outlays on mandatory spending for unemployment insurance 
and other economic support programs decreasing. 
For a detailed examination of why the budget moved from surplus to deficit, it is necessary to 
have a benchmark against which the actual deficit can be compared. One benchmark would be to 
compare the 2009 deficit to the 2001 surplus, but this approach would be fraught with several 
difficulties. For one thing, spending and revenues are expected to increase over time because of 
inflation and economic growth, among other factors, so that $1 spent in 2009 is not comparable to 
$1 spent in 2001. In addition, the economy in 2009 is not at the same level of production or in the 
same position in the business cycle as the economy in 2001, so the economy’s effect on the 
budget is not the same either. Finally, the same law yields different levels of spending or revenue 
over time. For example, entitlement spending can increase automatically if the number of 
beneficiaries increases. Therefore, comparing spending or revenue levels from one year to the 
next could give the false impression that policy had changed when it had not. 
This report uses a different benchmark: it compares the actual budget balance in the past nine 
years to CBO’s January 2001 baseline projection of the surplus for each of those years. Generally 
speaking, the baseline is a projection of the future path of government spending and revenues 
under current policy assuming no changes in the law. The purpose of baseline construction by 
CBO is to provide a neutral foundation for which to assess policy options, and it is not intended 
to predict future changes in revenue and spending legislation.6 The Deficit Control Act of 1985 
(P.L. 99-177) established specific rules for CBO to follow in calculating baseline projections, and 
additional information about budgetary baselines as it relates specifically to mandatory spending, 
federal revenues, and discretionary spending will be provided later in this discussion. CBO 
projected in 2001 that if policy had not changed, the surplus would have grown each year.7 Any 
year could have been chosen as the benchmark; this report uses CBO’s 2001 baseline as the 
benchmark because estimated 10-year surpluses peaked in this projection. In subsequent reports, 
the surplus projections would be continually adjusted downward, as CBO became progressively 
more pessimistic about the future path of deficits. Thus, the results that follow are partly a 
function of the benchmark chosen. 
Table 1 shows the differences between CBO’s January 2001 baseline projections and the actual 
budget balance for FY2001 to FY2009, attributing deficit increases to the legislative, economic, 
and technical categories. Legislative changes refer to enacted laws affecting revenue, mandatory 
spending, or discretionary spending. Along with spending increases and revenue reductions 
implemented by the enactment of new laws, legislative changes have also increased the national 
debt and the cost of debt servicing. The combined change in debt servicing attributed to the 
enactment of new legislation is reported separately in Table 1. Over the past 10 years, legislative 
changes have increased federal budget deficits by approximately $5.4 trillion. Each year since 
2003, legislative changes that increased the deficit were larger than the annual surplus projected 
by CBO in January 2001.

Notes: Negative numbers indicate an increase in the deficit. Columns may not be additive due to rounding. 
a.  In the January baseline, CBO does not report changes to the previous year deficit that occurred since the 
August baseline. Therefore, any changes between the actual deficit and the baseline deficit projected in 
August have been apportioned evenly between economic and technical changes.  
b.  With regards to the Troubled Asset Relief Program (TARP), CBO in January 2009 projected mandatory 
outlays at $184 billion for FY2009. Revised estimates of TARP budgetary impact were provided in March 
and August 2009 through the technical changes category. However, al  TARP spending in this table is 
accounted for as mandatory spending. It should also be noted that in January 2010 CBO projected a 
negative outlay level for TARP in FY2010 to reflect changes in economic and market conditions occurring 
since the actual FY2009 figure of $152 billion was recorded. This change is included in the total for technical 
changes.  
c.  CBO has accounted for Fannie Mae and Freddie Mac as federal operations since January 2009. In August 
2009, CBO estimated Fannie Mae and Freddie Mac FY2009 subsidy costs at $291 billion, which is the 
amount presented in this table. However, due to budgetary rules, when CBO released new baseline 
projections in January 2010, the actual FY2009 budgetary impact for these entities was scored as the level of 
Treasury Department cash infusions, which was $91 billion in FY2009. This change is included in the total 
for technical changes.

The Impact of Major Legislation on Budget Deficits: 2001 to 2009 
 
At the same time, independent of new legislation passed by Congress, economic variables such as 
inflation, the unemployment rate, and interest rates have affected both outlays and federal 
receipts, and CBO classifies these as economic changes. In addition, differences between budget 
projections and the actual annual deficit or surplus were also caused by modifications to CBO 
technical assumptions. For example, if more beneficiaries took up an entitlement benefit than 
projected, or if fewer taxpayers claimed a tax credit than projected, there would be a technical 
change to CBO’s projections. 
In 2009, legislative changes accounted for about $1.36 trillion of the shift from surplus to deficit 
that has occurred since the 2001 projection. Economic changes to the projection were small 
relative to legislative and technical changes. Although there was a severe recession not 
anticipated in the 2001 projection, the actual level of GDP in 2009 was still fairly close to what 
CBO had projected in 2001. Technical changes made up an estimated $614 billion of this shift to 
deficit, although almost half of those changes were due to CBO’s decision to move Fannie Mae 
and Freddie Mac on budget after the Treasury took them into conservatorship in 2008. Although 
CBO did not consider this to be a legislative change, it can be thought of as a policy change 
because it resulted in these entities receiving large-scale direct federal support. 
Mandatory Spending and Federal Revenues: 
2001 to 2009 
Mandatory Spending 
Mandatory spending (also referred to as direct spending) consists primarily of outlays on benefit 
programs such as Social Security, Medicare, and Medicaid. The level of spending dedicated to 
entitlement programs is determined by established rules of eligibility and benefit formulas. 
Consequently, mandatory spending outlays are allocated automatically and are not subject to the 
annual discretionary appropriations process. In regards to budgetary treatment of mandatory 
programs, CBO follows baseline construction rules specified in the Deficit Control Act of 1985 
(P.L. 99-177), where direct spending authorizations scheduled to expire by law are assumed to 
continue if outlays exceed $50 million, and the program under consideration was established prior 
to enactment of the Balanced Budget Act of 1997 (P.L. 105-33).8 
Mandatory spending outlays have accounted for a significant proportion of both federal spending 
and overall economic activity during the past decade (see Table 2).9 In particular, mandatory 
outlays have grown from 9.9% of GDP in FY2001 to 14.7% in FY2009. Among the key drivers 
of entitlement growth for FY2001 to FY2009, a cumulative $4.8 trillion was spent on Social 
Security benefits and $3.2 trillion was allocated for Medicare.10

The Impact of Major Legislation on Budget Deficits: 2001 to 2009 
 
Although mandatory spending has contributed significantly to increasing federal budget deficits 
over the past 10 years, much of this entitlement outlay growth stems from programs established 
before 2001.11 Consequently, because this report examines the budgetary impact of major laws 
enacted during the past five legislative sessions of Congress, mandatory programs such as Social 
Security, Medicare (Part A, Part B and Part C), and Medicaid will not be addressed in detail. 
It should also be noted that while direct spending outlays have increased in recent years, much of 
this entitlement growth was projected by CBO at the beginning of the decade when future budget 
surpluses were projected. As Table 2 indicates, CBO’s January 2001 budget baseline assumed 
mandatory outlay levels that exceeded actual amounts for every year from FY2001 to FY2007, 
with significant underestimation of actual direct spending only occurring for FY2009, when new 
mandatory spending on the Troubled Asset Relief Program (TARP), activities related to Fannie 
Mae and Freddie Mac, and other economic stabilization and economic stimulus initiatives were 
implemented largely in response to the U.S. financial crisis. Consequently, the expansion in 
entitlement spending was not a major determinant of the decade long shift from projected budget 
surpluses to actual budget deficits. 
Federal Revenues 
Similar to mandatory spending, the level of federal receipts is not directly determined by law. 
Instead, enacted revenue legislation specifies tax rates and various other features of the tax 
system, which in combination with economic conditions determine the actual level of revenues 
collected. The enactment of the Economic Growth and Tax Relief Reconciliation Act of 2001 
(EGTRRA; P.L. 107-16), the Jobs and Growth Tax Relief Reconciliation Act of 2003 (JGTRRA; 
P.L. 108-27), and other tax legislation impacted the level of federal revenue collected over the 
past 10 years, and will be discussed later in this report. In contrast to the budgetary treatment of 
mandatory spending, the CBO baseline assumes that most current tax provisions will expire as 
scheduled.12 
With respect to both total collections and as a share of the overall economy, federal receipts 
fluctuated between FY2001 to FY2009. Table 3 illustrates total federal revenues as a proportion 
of GDP peaked in FY2001 at 19.5%, declined to 16.1% by FY2004, before rebounding to a 
18.5% share of economic activity in FY2007. By FY2009, however, federal receipts reached their 
lowest level of the decade—14.8% of GDP. In dollar terms, revenue traced a similar trajectory, 
with receipts decreasing from $2.0 trillion in FY2001 to $1.8 trillion for FY2004, before 
increasing to a peak level of $2.6 trillion for FY2007, followed by two years of revenue decline. 
Individual income taxes, historically the largest source of federal revenue, peaked as proportion 
of GDP in FY2001 at 9.7%, before declining to 6.9% of GDP in FY2004. Individual income 
receipts increased during FY2005 to FY2007, but then declined to a decade low of 6.4% of GDP 
by FY2009.13 
                                                
11 For instance, the Social Security Act (P.L. 74-271) was signed into law in 1935, and the Social Security 
Amendments (P.L. 89-97), which created Medicare and Medicaid, were enacted in 1965.

Budget and Economic Outlook: Fiscal Years 2010 to 2020 (Box 4.1 Effect of Expiring Tax Provisions on CBO’s 
Revenue Baseline), January 2010. 
13 Data on federal revenues for FY2001 to FY2009 was collected from Congressional Budget Office, The Budget and

The Impact of Major Legislation on Budget Deficits: 2001 to 2009 
 
Impact of Major Legislation on Budget Deficits: 
2001 to 2009 
The following sections review legislation enacted from 2001 to 2009 with budgetary impact 
greater than $50 billion over 10 years. Most laws examined include key provisions that directly 
affect mandatory spending or federal revenues, but supplemental appropriations legislation 
related to “Global War on Terror” programs and 2005 Hurricane emergency relief is also covered. 
Annual appropriations providing for non-defense discretionary spending is discussed separately at 
the end of this report. It should also be noted that the measured impact of legislation does not 
include resulting increases in debt service costs. 
Table 4 presents the budgetary effect of legislative changes occurring from 2001 to 2009 relative 
to CBO’s January 2001 baseline projections. Laws passed by Congress in 2001 and 2003, notably 
the Economic Growth and Tax Relief Reconciliation Act of 2001 (EGTRRA; P.L. 107-16) and the 
Jobs and Growth Tax Relief Reconciliation Act of 2003 (JGTRRA; P.L. 108-27), generated the 
largest 10-year increases in budget deficits, about $1.7 trillion. Legislation enacted in FY2009, 
including the Emergency Economic Stabilization Act (EESA; P.L. 110-343) and the American 
Recovery and Reinvestment Act of 2009 (ARRA; P.L. 111-5), caused the 2009 deficit to increase 
by $509 billion, while legislative changes from 2001 to 2008 caused the 2009 deficit to increase 
by an additional $903 billion. For the decade as whole, it can be estimated that legislative changes 
have increased deficits, relative to the 2001 baseline projections, by about $5.4 trillion.

The Impact of Major Legislation on Budget Deficits: 2001 to 2009 
 
EGTRRA, JGTRRA and Other Major Tax Legislation 
From 2001 to 2006, several laws were enacted under the Bush Administration that reduced 
federal government revenues. However, since the Joint Committee on Taxation (JCT) and CBO 
typically measure the budgetary effect of revenue policy only when legislation is under 
consideration by Congress, the actual ex-post impact of specific laws on budget deficits can be 
difficult to determine.14 Consequently, in this section all CBO and JCT data on legislative cost is 
accompanied by both the approximate date of the estimate, as well as any needed clarification 
about the point in the legislative process when the estimate was performed. 
Economic Growth and Tax Relief Reconciliation Act of 2001 
On June 7, 2001, President Bush signed into law the Economic Growth and Tax Relief 
Reconciliation Act of 2001 (EGTRRA; P.L. 107-16). EGTRRA established a new 10% regular 
income tax bracket, gradually reduced various income tax rates through 2006, and increased the 
child tax credit to $1,000 over 10 years. Additionally, the law phased-in an increase in the basic 
standard deduction for married couples filing joint returns in order to provide marriage penalty 
relief, raised the annual limit on contributions to education individual retirement accounts (IRAs), 
and phased-in an increase in the unified credit exemption amount and a reduction of tax rates for 
estate and generation-skipping transfer taxes (including a complete repeal of estate and 
generation-skipping transfer taxes for 2010).15 To comply with the Congressional Budget Act of 
1974, most provisions in EGTRRA are scheduled to sunset at the end of calendar year 2010.16 
In May 2001, JCT estimated that EGTRRA, as cleared by Congress, would have a negative 
budgetary impact of $1.35 trillion for FY2001 to FY2011. Among the key components of the cost 
estimate, JCT expected the marginal rate reduction provisions to decrease government revenues 
by $874.9 billion over 10 years, and for the expanded child tax credit to cost $171.8 billion during 
the same timeframe.17 
Jobs and Growth Tax Relief Reconciliation Act of 2003 
The second major tax cut under the Bush Administration, the Jobs and Growth Tax Relief 
Reconciliation Act of 2003 (JGTRRA; P.L. 108-27), was enacted on May 28, 2003 and 
accelerated many of the tax reductions previously implemented by EGTRRA. In particular, for 
2003 and 2004 the increase in the child tax credit was raised to $1,000, and the basic standard 
deduction amount for married taxpayers filing a joint return was increased to twice the basic 
standard deduction amount for single individuals. Additional EGTRRA provision accelerations 
                                                
14 For a CBO discussion about the difficulties in measuring the budgetary impact of EGTRRA and JGTRRA, see 
Congressional Budget Office, The Budgetary Costs of EGTRRA and JGTRRA Compared with Projected Deficits, July 
20, 2007, available at http://www.cbo.gov/ftpdocs/83xx/doc8337/07-20-EGTRRA-JGTRRA_and_Deficits.pdf. 
15 For analysis of EGTRRA and a comparison of House, Senate and Administration proposals prior to enactment of the 
law, see CRS Report RL30973, 2001 Tax Cut: Description, Analysis, and Background, by David L. Brumbaugh et al. 
16 In contrast to the budgetary treatment of authorization legislation for mandatory programs, CBO assumes that most 
current tax provisions will expire as scheduled. Consequently, CBO projected in January 2010 projected that expiring 
tax provisions under EGTTRA, JGTRRA, and other legislation would increase revenues by 2.7% of GDP for FY2010 
to FY2012.

implemented by JGTRRA included an expansion of the 15% rate bracket for married couples 
filing joint returns, and an acceleration of the regular income tax rate reductions scheduled for 
2004 and 2006. JGTRRA also contained tax incentives for businesses such as a first-year 
depreciation allowance equal to 50% for certain property acquired after May 5, 2003, and before 
January 1, 2005, and provided for significant reductions in taxes on capital gains and dividends 
received prior to January 1, 2009.18 
In May 2003, JCT and CBO projected that JGTRRA, as enacted, would increase federal budget 
deficits by $349.7 billion for FY2003 to FY2013. The acceleration of previously enacted tax 
reductions was expected to cost $171.4 billion over the next five years, with new reductions in 
taxes on dividends and capital gains estimated to decrease government receipts by another $148.1 
billion. 19 
Other Tax Legislation With Budgetary Impact: 2004 to 2006 
In the 108th and 109th Congress, several laws were passed that extended and in some cases 
modified revenue reduction provisions previously enacted under EGTRRA and JGTRRA. The 
Working Families Tax Relief Act of 2004 (WFTRA; P.L. 108-311), signed into law on October 4, 
2004, extended tax relief for married taxpayers filing a joint return through 2008, maintained the 
$1,000 child tax credit through 2009, and extended the 10% income tax bracket through 2010. In 
September 2004, JCT and CBO estimated WFTRA would decrease federal revenues by $122.2 
billion over FY2005 to FY2014, while raising direct spending (mostly from increased outlays for 
refundable tax credits) by $23.8 billion over the same period, for a combined 10-year budgetary 
impact of $145.9 billion.20 
On May 17, 2006, another tax cut extension was signed into law, the Tax Increase Prevention and 
Reconciliation Act of 2005 (TIPRA; P.L. 109-222).21 TIPRA extended the reduced tax rates on 
capital gains and dividends through 2010 and extended the exception for active financing income 
for controlled foreign corporations, among other provisions. In June 2006, JCT projected that the 
conference agreement for TIPRA would reduce federal revenues by $69.1 billion for FY2006 to 
FY2015.22 
The Pension Protection Act of 2006 (PPA; P.L. 109-280), signed into law on August 17, 2006, 
provided comprehensive reform of U.S. pension law.23 PPA included several provisions that 
reduced federal government revenues, such as making permanent increases in limits on 
contributions to pension plans or IRAs first enacted under EGTRRA, and extending a non-

refundable credit available to low-income individuals contributing to either a 401(k) savings plan 
or an IRA (EGTRRA’s “Saver’s Credit”). In August 2006, JCT estimated that PPA, as cleared by 
Congress, would reduce federal revenues by $72.9 billion for FY2007 to FY20016, and CBO 
estimated that the legislation would decrease outlays on direct spending by $5.0 billion over 10 
years, for a total 10-year budgetary effect of $67.9 billion. 24 
In addition to legislation related to EGTRRA and JGTRRA, Congress routinely extends other 
expiring tax provisions. Among these tax extenders laws, only the Tax Relief and Health Care Act 
of 2006 (TRHCA; P.L. 109-432) meets the criteria of budgetary effect exceeding $50 billion 
specified above. TRHCA implemented numerous changes to tax law, including an extension 
through 2007 of the research and development credit, the deduction for state and local taxes, and 
the deduction for qualified tuition and related expenses. TRHCA also extended several expiring 
energy tax provisions through 2008 and made changes to rules governing Health Savings 
Accounts. 25 In December 2006, JCT and CBO estimated that the law would decrease federal 
government revenues by $40.0 billion for FY2007 to FY2016.26 In addition, CBO projected that 
direct spending provisions in TRHCA related to the Medicare payments for physicians’ fee 
services and other programmatic changes were expected to increase mandatory outlays by $10.5 
billion, and thus in combination TRHCA was estimated to raise deficits by $50.5 billion over 10 
years. 
Table 5 shows JCT and CBO estimated increases in federal budget deficits related to EGTRRA, 
JGTRRA, WFTRA, TIPRA, PPA and TRHCA. For each bill, the projected budgetary impact is 
presented over both a 5-year and 10-year budget window.

The Impact of Major Legislation on Budget Deficits: 2001 to 2009 
 
Notes: Negative numbers indicate an increase in the deficit. Columns may not be additive due to rounding. 
a.  Al  budgetary effects were estimated by CBO and JCT at the time of legislative enactment.  
b.  Budgetary effects reported for the Economic Growth and Tax Relief Reconciliation Act of 2001, the Jobs 
and Growth Tax Relief Reconciliation Act of 2003, the Working Families Tax Relief Act of 2004, and the 
Tax Increase Prevention and Reconciliation Act of 2005 include provisions related to the Alternative 
Minimum Tax (AMT).  
c.  For the Tax Relief and Health Care Act of 2006, budgetary effects for both revenue provisions, and direct 
spending provisions related to Medicare and other programs are reported in this table.  
The Alternative Minimum Tax: Increases in the Basic Exemption 
and Other Structural Modifications  
An alternative minimum tax (AMT) is intended to ensure that taxpayers with significant income 
pay a minimum amount of tax. An add-on minimum tax was originally passed by Congress 
through the Tax Reform Act of 1969 (P.L. 91-72), and the first AMT was enacted as part of the 
Tax Equity and Fiscal Responsibility Act of 1982 (P.L. 97-248).27 Provisions of the AMT have 
been modified numerous times since 1982, including through the Tax Reform Act of 1986 (P.L. 
99-514), and the Omnibus Budget Reconciliation Act of 1993 (P.L. 103-66).28 Under present law, 
the AMT is determined by subtracting a basic exemption amount from an individual’s calculated 
AMT tax base (computed by adding back various tax adjustments and preferences), with the 
remaining tax base assessed under a two-tiered rate structure of 26% for all income up to 
$175,000, and 28% on any income above this amount.29 
Over the past decade, the combined effects of inflation and new legislative reductions in federal 
income tax have increased concern in Congress about the growing number of taxpayers that 
might be affected by the AMT. In response, lawmakers have implemented numerous increases in 
the AMT basic exemption during the 107th to 111th Congresses.30 The enactment of EGTRRA in 
2001 temporarily raised the AMT exemption level to $49,000 for joint returns and $35,750 for 
unmarried individuals effective through 2004. JGTRRA increased the basic AMT exemption 
amount for 2003 and 2004 to $58,000 for joint returns and $40,250 for unmarried individuals. 
WFTRA extended the AMT patches provided in JGTRRA for 2005, and TIPRA increased the 
AMT exemption amount for 2006 to $62,550 for joint returns and $42,500 for unmarried 
individuals. Other recent AMT patches were enacted through the Tax Extenders and Alternative 
Minimum Tax Relief Act of 2008 (TEAMTRA; Division C of P.L. 110-343), and the American 
Recovery and Reinvestment Act of 2009 (ARRA; P.L. 111-5). 
Along with the periodic increases in the AMT patch passed by Congress, revenue legislation 
signed into law over the past 10 years has also modified other components of the AMT that 
reduced federal government revenues. For instance, EGTRRA allowed various nonrefundable

a.  Al  budgetary effects were estimated by JCT at the time of legislative enactment  
Agricultural Policy: 2002 and 2008 Farm Bills 
The Farm Security and Rural Investment Act of 2002 (2002 farm bill; P.L. 107-171) was signed 
into law on May 13, 2002, reauthorizing the major federal farm programs administered by the 
U.S. Department of Agriculture for FY2002 to FY2007. As mentioned in the above discussion on 
mandatory spending, under baseline construction rules direct spending programs are assumed to 
continue even after expiration of current law. Thus, the impact of the 2002 farm bill on federal 
budget deficits was not measured in terms of the total mandatory outlays to be spent on 
agricultural programs covered by the legislation, but instead as compared to the level of March 
2002 baseline direct spending that would have occurred during the budgetary window under 
provisions of the previous farm bill, the Federal Agriculture Improvement and Reform Act of 
1996 (1996 farm bill; P.L. 104-127), as amended. 
In May 2002, CBO estimated that the 2002 farm bill would increase federal budget deficits by 
$49.2 billion over FY2002 to FY2007, bringing total spending on federal farm programs to 
$470.5 billion over six years when baseline spending is included.31 Among the largest

expenditures, CBO expected the 2002 farm bill to increase direct spending on commodity support 
programs by $37.6 billion over six years, and to increase outlays on agricultural conservation 
programs by $6.5 billion during the same period. 
In the 110th Congress, the main agricultural policies contained in P.L. 107-171 were reauthorized 
through the Food, Conservation, and Energy Act of 2008 (2008 farm bill; P.L. 110-246).32 Similar 
to P.L. 107-171, financing for most programs covered in the 2008 farm bill only extend through a 
limited number of years, FY2008 to FY2012. Relative to CBO’s March 2008 baseline projection 
of $301.4 billion in federal farm program direct spending over five years, the 2008 farm bill was 
projected in May 2008 to increase mandatory spending by another $5.6 billion for FY2008 to 
FY2012, while raising $5.0 billion in federal revenues.33 Consequently, although P.L. 110-246 is 
estimated to cover approximately $307.0 billion in spending over FY2008 to FY2012, the 
increase in federal deficits scored by CBO is only $0.6 billion. 
As estimated by CBO at the time of legislative enactment, the 2002 and 2008 farm bills combined 
generate federal budget deficits of $49.8 billion for their authorized time windows. However, due 
to the five-month gap between the scheduled expiration of mandatory program authorization 
under P.L. 107-171 and the enactment of P.L. 110-246, the actual increase in federal budget 
deficits is likely greater than this combined level. Further, it should be noted that if the 2008 farm 
bill was scored against CBO’s March 2002 baseline, which assumed continuation of the 1996 
farm bill, the 2008 reauthorization would have increased budget deficits by $38.7 billion for 
FY2008 to FY2012. Thus the combined budgetary effect of the 2002 and 2008 farm bills would 
be $87.9 billion if scored collectively against the March 2002 baseline. 
Funding for Military Operations in Afghanistan, Iraq and Other 
Global War on Terror Programs 
Over the past 10 years, Congress enacted legislation financing military operations in Afghanistan, 
Iraq, and other countries, generating significant long-term budgetary effects. From FY2001 to 
FY2009, support for Global War on Terror (GWOT) operations has been provided primarily 
through emergency supplemental appropriations law.34 Some funds for war programs have also 
been made available through regular annual appropriations legislation, such as the Department of 
Defense Appropriations Act, 2005 (P.L. 108-287) and the Foreign Operations, Export Financing, 
and Related Programs Appropriations Act, 2006 (P.L. 109-102). 
Table 7 shows all legislation enacted during the 107th to 111th Congresses supporting GWOT 
operations through the end of FY2009. Appropriations for each law are reported for the following

Another way to view the cost of military operations in Iraq, Afghanistan, and related GWOT 
activities is to examine the amount of funding appropriated for each major operation. Table 8 
presents the FY2001 to FY2009 aggregated spending levels for Operation Enduring Freedom 
(OEF), which covers ongoing operations in Afghanistan, the Philippines, Somalia and other 
nations; Operation Iraqi Freedom (OIF); and Operation Noble Eagle (ONE), which provides 
additional security for U.S. military bases and for homeland security purposes. Of the $943.8

a.  For the memorandum, the total includes war spending.  
Funding for GWOT operations has been provided primarily through supplemental appropriations, 
whereas other changes in national defense policy have been implemented through regular defense 
appropriations law. As shown in Table 8, relative to CBO’s January 2001 baseline, which held 
projected military outlays for FY2001 to FY2009 constant in inflation-adjusted terms, annual 
national defense spending (including both regular and supplemental appropriations) has increased 
by about $1.3 trillion over the past nine years. 
Sustainable Growth Rate System: Medicare Physician 
Payment Updates 
Since the establishment of the Medicare program in 1965, various methods have been used to 
determine physician payment rates for covered medical services.35 In an effort to better control 
Medicare’s outlays for physician services, the Balanced Budget Act of 1997 (P.L. 105-33) 
implemented the current Sustainable Growth Rate (SGR) system, which sets target levels for 
health expenditures, and adjusts payment rates to account for differences between cumulative 
Medicare spending and spending goals. Under the SGR system, when actual spending does not

exceed the expenditure targets, the annual physician fee schedule updates are calculated as 
determined in statue based on the annual change in the Medicare economic index (MEI), changes 
in the Medicare population, and other factors.36 Although expenditures did not begin to exceed 
SGR targets until 2002, this discrepancy between actual costs and payment limits has grown 
larger in each subsequent year.

Services Under the SGR System

Notes: Positive numbers shown in this figure indicate that actual expenditures did not exceed target 
expenditures al owed under the SGR system for 1996 to 2001. Negative numbers indicate that actual 
expenditures exceeded the SGR targets beginning in 2002. 
The cumulative difference between allowed and actual expenditures from 1996 to 2008 is shown 
in Figure 1. For the second quarter of 2002, actual physician service expenditures exceeded 
allowed levels under SGR by $0.6 billion. However, this cumulative difference grew to $24.4 
billion by the start of 2005, and has expanded rapidly to an estimated $63.6 billion difference by 
the last quarter of 2008.

The Impact of Major Legislation on Budget Deficits: 2001 to 2009 
 
To avoid the reductions in physician fee schedules that have been mandated since 2003 under 
SGR, Congress has passed several legislative overrides. The Consolidated Appropriations 
Resolution of 2003 (P.L. 108-7) replaced the scheduled 4.4% payment rate reduction with a 1.6% 
increase in rates for 2003. The Medicare Prescription Drug, Improvement, and Modernization Act 
of 2003 (MMA; P.L. 108-173) replaced rate reductions in 2004 and 2005 with increases of 1.5% 
for both years. More recently, legislative overrides to physician fee payment decreases mandated 
under SGR were enacted through the Tax Relief and Health Care Act of 2006 (TRHCA; P.L. 109-
432), the Medicare, Medicaid, and SCHIP Extension Act of 2007 (MMSEA; P.L. 110-173), the 
Medicare Improvement for Patients and Providers Act of 2008 (MIPPA; P.L. 110-275), and the 
Temporary Extension Act of 2010 (P.L. 111-144). Table 9 reports the legislative overrides to 
scheduled cuts in Medicare physician fees signed into law during the 108th to 111th Congresses.

Title XVIII of the Social Security Act. MMA specified that drug coverage be delivered to 
beneficiaries through either a private prescription drug plan, or prescription drug coverage 
integrated into Medicare Part C, with all plan providers offering at a minimum “standard

coverage,” or alternative coverage with actuarially equivalent benefits.37 Another key provision of 
MMA was the establishment of the Medicare Advantage (MA) program under Part C, which 
replaced Medicare+Choice. In addition, the legislation provided for Medicare cost containment 
initiatives and changes to Medicare’s fee-for-service program. 
Table 10 shows that CBO’s original calculation projected net Medicare Part D outlays to increase 
federal budget deficits by approximately $552.2 billion over the next decade. In particular, CBO 
estimated that for FY2004 to FY2013 Medicare Part D would require $771.3 billion in payments 
for benefits and mandatory administrative costs. However, during this same 10-year budget 
window CBO also anticipated these expenditures to be partially offset by $130.6 billion in 
premiums paid by beneficiaries, and another $88.5 billion in payments made by states.38 In 
addition, other provisions of MMA, including $12.5 billion in savings from changes to Medicare 
Part A and Part B, and $144.7 billion in expected savings from reduced spending on Medicaid and 
other federal programs was originally projected by CBO to reduce the total cost of the legislation 
to $395.0 billion over 10 years.

The Impact of Major Legislation on Budget Deficits: 2001 to 2009 
 
Trustees 2009 report showed total spending on the prescription drug benefit for FY2004 to F2008 
at about $105.9 billion, which was lower than the $147.0 billion amount originally projected by 
CBO over the same budget window.39 Further, this most recent Medicare Trustees report also 
projects Part D expenditures for FY2009 to FY2013 at $275.4 billion, which is also lower than 
the $405.2 billion outlay level originally estimated by CBO for this time period. It should be 
noted that other provisions of MMA that were originally anticipated to create budgetary savings 
through changes in Medicare Part A and Part B, and reduced Medicaid spending are challenging 
to quantify in terms of actual expenditures, and are not included in the annual Medicare Trustees 
reports. 
Deficit Reduction Act of 2005 
The Deficit Reduction Act of 2005 (DRA; P.L. 109-171), signed into law by President Bush on 
February 8, 2006, stipulated significant reductions in mandatory spending for a variety of 
government programs. In regards to student loan programs, DRA mandated lower payments to 
education lenders, an increase in the interest rate charged on loans to parents of students, and 
decreased insurance reimbursements for lenders, among other changes. DRA also impacted 
Medicaid by permitting states to charge beneficiaries higher premiums, while also reducing 
Medicaid payments for outpatient prescription drugs. P.L. 109-171 also included provisions that 
decreased Medicare spending, increased collections from spectrum license auctions administered 
by the Federal Communication Commission, and raised premiums paid by private companies to 
the Pension Benefit Guaranty Corporation. 
As part of CBO’s March 2006 analysis of the President’s FY2007 Budget, it was estimated that 
DRA would reduce mandatory spending by approximately $106 billion for FY2007 to FY2016.40 
Included in this cost projection, the programmatic changes to Medicaid and Medicare were 
expected to decrease net federal spending respectively by $40 billion and $21 billion over 10 
years, whereas student loan program provisions were anticipated to generate net budgetary 
savings of about $30 billion over this time period. 
Emergency Funding in Response to 2005 Hurricanes:  
Katrina, Rita, and Wilma 
In the aftermath of Hurricanes Katrina, Rita, and Wilma, several emergency supplemental 
appropriations laws were enacted during the 109th and 110th Congresses, adding significantly to 
federal budget deficits.41 In September 2005, Congress passed two bills related to Hurricane 
Katrina emergency relief and recovery efforts, P.L. 109-61 and P.L. 109-62, providing a combined

$62.3 billion in supplemental funds.42 Department of Defense appropriations measure in 2006 
(P.L. 109-148) provided $29.0 billion to fund the restoration of federal facilities damaged by the 
three hurricanes, and another $20.0 billion was made available through a emergency 
supplemental appropriations law (P.L. 109-234), which supported recovery assistance performed 
by the Department of Agriculture and the Natural Resources Conservation Service, among 
others.43 The 2007 emergency supplemental bill financing military operations in Iraq and 
Afghanistan (P.L. 110-28) included an estimated $6.9 billion for the Department of Homeland 
Security, the U.S. Army Corps of Engineers, and other agencies to provide Gulf Coast relief, and 
another supplemental law (P.L. 110-239) allocated $2.9 billion for ongoing disaster relief related 
to the 2005 Hurricanes.44

Additionally in the 109th Congress, tax legislation related to 2005 Hurricane recovery was 
enacted, reducing federal government revenues over several years. The Katrina Emergency Tax 
Relief Act of 2005 (P.L. 109-73) contained various types of tax relief, including a temporary 
suspension of limitations for qualified corporate and individual charitable contributions, and an 
extension of the replacement period for non-recognition of gain for property located in the 
Hurricane Katrina disaster area. In late September 2005, JCT estimated that P.L. 109-73 would 
reduce federal revenues by $6.3 billion for FY2006 and FY2007.45 The Gulf Opportunity Zone 
Act of 2005 (P.L. 109-135) offered numerous tax incentives related to business activities in the 
Gulf Cost, and was estimated by JCT to reduce government revenues by $8.7 billion for FY2006 
to FY2015.46 
Financial Crisis of 2008 
Federal Conservatorship of Fannie Mae and Freddie Mac  
The Housing and Economic Recovery Act of 2008 (HERA; P.L. 110-289), signed into law on 
July 30, 2008, implemented numerous changes in federal housing policy. Among other 
provisions, HERA authorized the Treasury Secretary to purchase obligations and other securities 
issued by government-sponsored enterprises (GSEs) involved in the mortgage market, and 
established the Federal Housing Finance Agency (FHFA) as the new single regulator for these 
GSEs. 
On September 6, 2008, the Director of FHFA exercised authority provided under HERA to place 
two GSEs, the Federal National Mortgage Association (Fannie Mae) and the Federal Home Loan 
Mortgage Corporation (Freddie Mac), into conservatorship. FHFA defines conservatorship as “the 
legal process in which a person or entity is appointed to establish control and oversight of a 
Company to put it in a sound and solvent condition. In a conservatorship, the powers of the 
Company’s directors, officers, and shareholders are transferred to the designated Conservator.” 47 
At the same time, the Treasury Department contracted with Fannie Mae and Freddie Mac to make 
direct cash infusions to maintain their solvency and liquidity. Specifically, Treasury pledged to 
purchase senior preferred shares in Fannie Mae and Freddie Mac paying 10% annual dividends,

and mortgage-backed securities issued by the firms. In return, Treasury received $1 billion of 
senior preferred shares and warrants for 79.9% of these GSEs’ common shares.48 
Because of this high level of government control, CBO concluded that Fannie Mae and Freddie 
Mac were now effectively federal operations and has accounted for the mortgages owned or 
guaranteed by these entities as loans and loan guarantees of the federal government since January 
2009.49 Treatment of GSE cost by CBO is similar to the budgetary consideration of federal credit 
programs under the Federal Credit Reform Act of 1990, in which the budget records a subsidy 
cost for federal loan commitments, with total budgetary impact calculated by discounting future 
loan cash flows by interest rates on Treasury securities with comparable maturity. However, in the 
case of Fannie Mae and Freddie Mac, CBO replaces the Treasury discount rates with rates 
reflecting the market risk associated with the GSEs’ credit obligations.50 
In August 2009, CBO estimated that the operations of Fannie Mae and Freddie Mac would 
increase the FY2009 federal deficit by $291 billion. Included in this estimate was the $248 billion 
subsidy cost for the GSEs’ assets and liabilities at the beginning of the conservatorship, along 
with another $43 billion in subsidy costs associated with new business undertaken by Fannie Mae 
and Freddie Mac in FY2009. Additionally, CBO projected that the activities of these entities 
would add $99 billion to federal budget deficits for FY2010 to FY2019. Table 12 presents the 
estimated budgetary effect of Fannie Mae and Freddie Mac conservatorship, as reported in CBO’s 
January and August 2009 baseline projections.

Since CBO determined Fannie Mae and Freddie Mac should be accounted for in the federal 
budget, the Treasury cash infusions are considered intragovernmental payments, and thus have no 
effect on federal budget deficits. In contrast to CBO, the Office of Management and Budget 
(OMB) continues to treat Fannie Mae and Freddie Mac as nongovernmental entities for federal 
budgeting purposes. Consequently, OMB does not include GSE subsidy costs in its budget 
estimates, but instead scores the Treasury cash infusions as the total budgetary effect of federal

Notes: In January 2010, CBO recorded $91 billion in net outlays related to Fannie Mae and Freddie Mac for 
FY2009. This reflects $96 billion in Treasury cash infusions offset moderately by over $4 billion in dividends from 
Fannie Mae and Freddie Mac stock. At this time, no projections were offered about Treasury GSE cash infusions 
for FY2010 to FY2019. 
Because of budgetary rules, when CBO released new baseline projections in January 2010, the 
actual FY2009 budgetary impact for Fannie Mae and Freddie Mac was scored as the level of net 
outlays from Treasury cash infusions, and not as the net subsidy cost associated with federal 
conservatorship. In particular, CBO recorded a value of $91 billion for the two GSEs in FY2009, 
reflecting almost $96 billion in cash infusions offset moderately by more than $4 billion in 
dividends on Fannie Mae and Freddie Mac stock.51 At the same time, as part of this January 2010 
estimate, CBO projected GSE future budgetary impact for FY2010 to FY2020 in terms of subsidy 
costs, and not as net outlays on Treasury cash infusions. 
Emergency Economic Stabilization Act of 2008 
The Emergency Economic Stabilization Act of 2008 (EESA; Division A of P.L. 110-343) was 
signed into law on October 3, 2008, establishing the Troubled Asset Relief Program (TARP).52 
Under TARP, the Treasury Secretary is authorized to purchase or insure up to $700 billion of 
mortgage related assets, or any other assets the Secretary, in consultation with the Chairman of 
the Federal Reserve, determine would be required to promote stability in the financial markets.53 
Among the major TARP initiatives, the Capital Purchase Program has been used by the Treasury 
to purchase senior preferred shares from U.S. financial institutions. In addition, Treasury has 
invested $20 billion in both Bank of America and Citigroup through the Targeted Investment 
Program, provided loans and equity investments to General Motors, GMAC, Chrysler, and 
Chrysler Financial under the Automotive Industry Financing Program, and offered various forms 
of financial assistance to the American International Group.

mandatory authorization by $1.24 billion. 
Congressional Research Service 
25 
The Impact of Major Legislation on Budget Deficits: 2001 to 2009 
 
Similar to CBO’s budgetary treatment of Fannie Mae and Freddie Mac, Section 123 of EESA 
stipulates that accounting for the budgetary impact of TARP must be conducted under procedures 
outlined in the Federal Credit Reform Act of 1990, but with an adjustment for market risk. In 
particular, CBO is not recording the gross cash disbursement of Treasury purchases initiated 
under TARP, but is instead estimating the government’s net subsidy costs on a present value basis. 
Generally speaking, CBO calculates the subsidy costs for the TARP program by subtracting the 
purchase cost from the estimated market of the value acquired assets, discounted at a rate 
reflecting market risk.54 
The expected effect of EESA on federal budget deficits has been revised numerous times. In 
January 2009, CBO estimated that subsidy costs for TARP transactions would total $184 billion 
for FY2009 and $5 billion for FY2010. However, in March 2009, changes in market conditions 
and increased subsidy costs attributed to new Treasury Department transactions prompted CBO to 
increase its projected cost to $336 billion for FY2009 and $20 billion for FY2010. Because of 
improved market conditions, CBO in August 2009 once again revised the estimated budgetary 
impact of TARP, reducing projected outlays to $133 billion for FY2009, but increasing 
anticipated subsidy costs to $108 billion for FY2010 to FY2019. In January 2010, CBO provided 
another revision to TARP subsidy costs, recording an actual FY2009 subsidy of $152 billion. As 
circumstances have changed since the recording of this figure, a credit re-estimate was provided 
for FY2010 through a projected negative outlay of $67 billion. (The negative outlay of $67 billion 
does not reflect TARP spending that will take place in 2010.) Consequently, as of January 2010, 
CBO estimates a budgetary impact of $99 billion for the full duration of the TARP program.55 
Table 14 presents TARP cost estimates as reported in CBO’s January 2009, March 2009, August 
2009, and January 2010 baseline projections.

The Impact of Major Legislation on Budget Deficits: 2001 to 2009 
 
Economic Stimulus 
In response to the deep and long recession that began in December 2007, two major bills were 
enacted to stimulate the economy. 
Economic Stimulus Act of 2008 
On February 13, 2008, President Bush signed into law the Economic Stimulus Act of 2008 (P.L. 
110-185). The key provision in P.L. 110-185 was a refundable tax rebate which equaled 10% of 
an individual’s first $6,000 of taxable income ($12,000 for couples), with a minimum rebate of 
$300 ($600 for couples) and a maximum of $600 ($1,200 for couples). This rebate was phased-
out at a 5% rate for income over $75,000 for individuals ($150,000 for couples), with a full 
phase-out at $87,000 ($174,000 for couples).56 Further, a $300 rebate was available to individuals 
with no tax liability provided that earned income, Social Security benefits, and veterans disability 
payments totaled at least $3,000. Along with the rebate for individuals, P.L. 110-185 also included 
two business tax deductions. One provision allowed businesses to deduct 50% of investments 
made in 2008 on certain equipment, and another provision increased deductions permitted for 
small businesses under Section 179 of the Internal Revenue Code for purchases of certain types

In February 2008, JCT projected that P.L. 110-185 would increase federal budget deficits by 
approximately $124.5 billion over FY2008 to FY2018.57 Most significantly, the individual tax 
rebate was expected to reduce federal government revenues by $106.7 billion in FY2008 and by 
$10 billion in FY2009. Additionally, the 50% bonus depreciation on certain equipment placed in 
service in 2008 was estimated to reduce federal government revenues by $43.9 billion in FY2008, 
and by $5.6 billion in FY2009. However, since this business tax provision involved bringing the 
deduction forward in time, JCT estimated that the provision would effectively increase revenue 
by $42.1 billion over FY2010 to FY2018, with a net 10-year effect of a $7.4 billion revenue 
decrease.

American Recovery and Reinvestment Act of 2009 
In response to significant weakness in the U.S. economy, President Obama signed into law the 
American Recovery and Reinvestment Act of 2009 (ARRA; P.L. 111-5) on February 17, 2009. 
Division A of ARRA provided discretionary spending authority for a broad range of agencies, 
programs, and activities, including major authorizations for the State Fiscal Stabilization Fund 
and energy and water development initiatives.58 Division B of ARRA contained numerous direct 
spending provisions that offered fiscal relief to states under the Medicaid program, increased 
benefits for the Temporary Assistance for Needy Families program, extended unemployment 
compensation, and provided subsidies for COBRA health insurance premiums. Division B of 
ARRA also contained several tax provisions including the Making Work Pay tax credit, which 
was a temporary refundable tax credit of up to $400 for individuals and $800 for married couples 
for tax years 2009 and 2010. Further, ARRA expanded the Hope education tax credit for 2009 and 
2010, modified and extended the first-time homebuyer tax credit, and expanded certain rules 
related to net operating losses for businesses.59 
CBO and JCT estimated in February 2009 that ARRA would increase federal budget deficits by 
$787.2 billion over FY2009 to FY2019.60 For Division A, CBO projected discretionary spending 
outlays of $34.8 billion in FY2009, $110.7 billion for FY2010, with discretionary outlays totaling 
$308.3 billion over FY2009 to FY2019. With respect to direct spending provisions in Division B 
of ARRA, CBO estimated federal budget deficit increases of $85.3 billion in FY2009, $108.6 
billion for FY2010, with mandatory outlays totaling $267.0 billion over 10 years. Finally, JCT 
estimated that Division B tax provisions would decrease federal government revenues by $64.8 
billion in FY2009, $180.1 billion in FY2010, and by $211.8 billion over FY2009 to FY2019.

The Impact of Major Legislation on Budget Deficits: 2001 to 2009 
 
Table 16 presents the budgetary impact of discretionary spending, mandatory spending, and 
revenue provisions of ARRA, as estimated by CBO and JCT in February 2009. 
In January 2010, CBO released a revised projection for the budgetary impact of ARRA, 
anticipating that the law would now increase deficits by $75 billion above the original cost 
estimate, to $862 billion over FY2009 to FY2010.61 The modification to CBO’s cost projection 
for ARRA is attributed in part to increased outlays on unemployment compensation, which as of 
January 2010, were calculated to be approximately $21 billion greater than initially anticipated 
for 2009 and 2010. In addition, the Build America Bond program, a tax credit bond option for 
state and local governments established under ARRA, experienced participation levels 
significantly exceeding the original expectations of CBO and JCT. Consequently, CBO’s January 
2010 revision to the ARRA cost estimate projects an additional $26 billion in outlays for the 
program over FY2010 to FY2019. CBO’s revised ARRA cost projection also included new 
estimates related to Medicaid spending and the Making Work Pay tax credit.

The Impact of Major Legislation on Budget Deficits: 2001 to 2009 
 
Changes in Non-Defense Discretionary Spending: 
2001 to 2009 
Discretionary spending supports a variety of defense, domestic and international federal 
government operations, with the latter two categories comprising non-defense discretionary 
spending. Domestic discretionary spending funds numerous federal agencies and programs, 
including education, law enforcement, and energy, while discretionary spending on international 
programs includes financing for diplomatic missions and foreign aid. In relative terms, domestic 
outlays comprised about 93% of total annual non-defense discretionary spending during FY2001 
to FY2009, while international outlays made up the remaining 7%. With regards to legislation, 
annual appropriations laws provides the budget authority for discretionary spending, which can 
be granted both for a single year or over a longer time horizon. 
Table 17 shows non-defense discretionary spending over the past decade, both in nominal and 
constant dollars, and as a percentage of GDP. Adjusted for inflation, domestic and international 
outlays increased from $391.0 billion in FY2001 to approximately $477.4 billion in FY2006 (in 
FY2005 dollars). After declining in constant dollars in 2007, non-defense discretionary spending 
reached its peak for the decade in FY2009 at $516.2 billion, due in large part to economic 
stimulus initiatives related to the 2008 financial crisis. Compared with the size of the economy as 
a whole, non-defense discretionary spending equaled 3.4% of GDP in FY2001, comprised 
approximately 3.8% of GDP for FY2003 to FY2006, and has risen to 4.1% of GDP for FY2009.62

The Impact of Major Legislation on Budget Deficits: 2001 to 2009 
 
Unlike mandatory spending or revenue provisions that are authorized permanently or for several 
years at a time, appropriation levels are determined annually. This means that there is no 
straightforward way to project spending levels under current policy in the future, and hence no 
straightforward way to estimate discretionary policy changes over time. Under the Deficit Control 
Act of 1985 (P.L. 99-177), CBO is required to project future discretionary spending as the level of 
budget authority for the current fiscal year, adjusted using the employment cost index and the 
GDP deflator. Consequently, one way to measure policy changes in non-defense discretionary 
spending over the past decade is to compare the baseline level of constant spending adjusted for 
inflation projected by CBO in January 2001, against actual non-defense discretionary outlays for 
FY2001 to FY2009. Under this approach, which is illustrated in Figure 2, actual FY2002 non-
defense discretionary spending was $17 billion above the level estimated by CBO in January 
2001 and $81 billion above constant spending in FY2006. Due largely to economic stimulus 
spending implemented by the American Recovery and Reinvestment Act of 2009 (ARRA; P.L. 
111-5), actual non-defense discretionary spending for FY2009 was $135 billion above this 
constant spending benchmark. 
Another way to benchmark current policy for non-defense discretionary outlays is to keep 
spending constant as a share of GDP. This benchmark could be justified on the grounds that non-
defense discretionary spending has stayed relatively constant as a percentage of GDP over the 
past 25 years. Figure 2 compares actual non-defense discretionary outlays during this time period 
to outlays fixed at the FY2001 non-defense discretionary spending share of GDP, which was 
3.4%. Because GDP tends to grow faster than inflation, this benchmark typically yields smaller 
estimates of legislative changes to discretionary spending than the inflation-adjusted benchmark. 
Under this approach, actual non-defense outlays in FY2002 were $31.4 billion above the 
benchmark and $103.1 billion above the benchmark for FY2009.
