The Budget for Fiscal Year 2007
Summary
The Senate passed its version of the fiscal year (FY) 2007 budget resolution
(S.Con.Res. 83) on March 16, 2006. The House Budget Committee cleared its
version of the budget resolution (H.Con.Res. 376) on March 29. The House has not
yet (as of April 20) considered the resolution.
The President’s FY2007 budget released in early February 2006 included
proposals to make the 2001 and 2003 tax cuts permanent; slow the growth of
Medicare spending; hold funding for non-defense, non-homeland security funding
to little if any increase; and introduce, in FY2010, private accounts for Social
Security. The budget also assumed that relief from the expanding coverage of the
alternative minimum tax (AMT) will end after FY2007 and did not assume any
funding for the war on terror after FY2007. Under these assumptions, and others, the
deficit would shrink (in dollars) through FY2010 before rising slightly in FY2011.
The Congressional Budget Office’s (CBO’s) January 2006 budget report
provided baseline estimates and projections through FY2016. The baseline,
following required guidelines, assumed most current policies remain in place
throughout its ten-year forecast period. The expiration of the 2001 and 2003 tax cuts,
as current law requires, produces a large revenue increase in FY2011 that shrinks the
deficit and results in a small surplus in FY2012 (and through FY2016). The baseline
also assumed, as required, that discretionary spending would grow at the rate of
inflation, that supplemental funding approved in 2005 for the war on terror and
hurricane relief is repeated annually, the AMT is in full effect after FY2005, and
mandatory spending continues growing without legislative constraints. CBO’s
March 2006 estimates of the President’s proposals (using CBO’s underlying
assumptions and budget estimating methods) produced budget numbers similar in
most years to those in the Administration’s FY2007 budget for FY2007 through
FY2011.
CBO’s January report included the estimated cost of a number of alternative
policies that may better forecast the budget outlook than the policies assumed in the
baseline. The cost of extending or making permanent the tax cuts and maintaining
AMT relief are enough to eliminate the possibility of reaching a surplus. Faster
discretionary spending growth and growth rates closer to the historical rates would
also make it more difficult to reduce the deficit and reach a surplus.
Over the longer term, the retirement of the baby boom generation will put
enormous pressure on the federal budget and the economy. Neither the
Administration nor CBO believe that current policies, particularly current federal
policies for the elderly, can be sustained. Absent significant policy change, the effect
of the growing numbers of recipients for federal programs will disrupt not only the
programs themselves, but also the rest of the federal budget, the ability of the
government to finance its obligations, and, possibly, the ability of the economy to
support the expansion of government spending.
This report will be updated as events warrant.

The Budget for Fiscal Year 2007
Background and Analysis
Presidents submit their budget proposals for the upcoming fiscal year (FY) early
in each calendar year. The Bush Administration released its FY2007 budget (The
Budget of the U.S. Government, Fiscal Year 2007)
on February 6, 2006. The
multiple volumes contain both general and specific descriptions of the
Administration’s policy proposals and expectations for the budget for FY2006 (still
underway) through FY2011. It includes a section on long-term fiscal issues facing
the nation and provides limited information on the revenue and mandatory spending
changes after 2011. The full set of budget documents (Budget, Appendix, Analytical
Perspectives, Historical Tables
, among several other supplemental budget
documents) contains extensive and detailed budget information, including estimates
of the budget without the proposed policy changes (current service baseline
estimates), historical budget data, detailed budget authority, outlay and receipt data,
selected analysis of specific budget related topics, and the Administration’s economic
forecast.1 In addition to their presentation of the Administration’s proposals, the
budget documents are an annual reference source for federal budget information,
including enacted appropriations.
The Administration’s annual budget submission is followed by congressional
action on the budget. This usually includes the annual budget resolution,
appropriations, and, possibly, a reconciliation bill (or bills) as required by the budget
resolution. Over the course of deliberation on the budget, the Administration often
revises its original proposals as it interacts with Congress and as conditions change
in the economy and the world.
The Current Situation
On March 16, 2006, the Senate passed its version of the congressional budget
resolution (S.Con.Res.83) for FY2007. The resolution included higher discretionary
spending than requested by the President and did not include any reconciliation
instructions to reduce mandatory spending or to reduce taxes. The House Budget
Committee passed its verison of the congressional budget resolution (H.Con.Res.
1 Current services baseline estimates, and baseline estimates in general, are not meant to be
predictions of future budget outcomes, but instead are designed to provide a neutral measure
against which to compare proposed policy changes. In general, they project current policy,
which includes future changes in law, over the next 5 to 10 years. Their construction
generally follows instructions provided in the Balanced Budget and Emergency Deficit
Control Act of 1985 (DCA) and the Congressional Control and Impoundment Act of 1974.

376) on March 29. Although scheduled for floor action the week of April 3,
disagreements within the majority over the resolution put off its consideration until
after the Easter break.
The Congressional Budget Office (CBO) released its first budget report in this
calendar year, the Budget and Economic Outlook: Fiscal Years 2007-2016, on
January 27, 2006. The report contains CBO’s baseline budget and economic
estimates and projections for the next 10 fiscal years. The Administration released
the President’s FY2007 budget proposals, including information through FY2011,
on February 6, 2006. The numbers in the President’s budget incorporate his
proposed policy changes.
CBO released its analysis of the President’s policy proposals for FY2007 on
March 15, 2006. The reestimates for FY2007 showed a slightly smaller deficit,
slightly smaller outlays, and larger receipts than what was shown in the President’s
budget.
Budget Totals
Table 1 contains budget estimates for FY2007 from the CBO and the
Administration (the Office of Management and Budget, OMB). Differences in totals
can result from differing underlying economic, technical, and budget-estimating
assumptions and techniques, as well as differences in policy assumptions. At the
outset, the policy-generated dollar differences for an upcoming fiscal year may be
relatively small compared to the budget as a whole. These small differences,
however, may grow over time — sometimes substantially — producing widely
divergent future budget paths. Budget estimates generally should be expected to
change over time from those originally proposed or estimated by the President, CBO,
or Congress.

Budget Estimates and Proposals
CBO’s first budget report for FY2007, the Budget and Economic Outlook:
Fiscal Years 2007-2016 (January 2006), contained baseline and economic estimates
and projections for FY2006 through FY2016. The report estimated an FY2007
baseline deficit of $270 billion (down from the estimated FY2006 baseline deficit of
$337 billion). By FY2011, the CBO baseline deficit estimate had fallen to $114
billion. The next year, FY2012, the increased receipts from the expiration of the
2001 and 2003 tax cuts produce a small baseline surplus estimate of $38 billion. The
small surplus estimates (never exceeding $75 billion, or 0.4% of GDP) persist
through FY2016.
Under the baseline assumptions, CBO increases discretionary spending at the
rate of inflation, assumes that the 2001 and 2003 tax cuts fully expire after 2010 (as
required under current law), and allows the recently lapsed alternative minimum tax
(AMT) relief to remain lapsed. The effects of these assumptions raise receipts in the
near-term and increase receipts by substantial amounts after FY2010 when most of
the tax cuts from 2001 and 2003 expire under current law. The declining deficit and
appearance of small surpluses over the 10 years in the CBO baseline are largely
explained by the baseline construction rules that CBO must follow. The results likely
understate the future size and persistence of the deficit, as CBO acknowledges in its
report.
CBO’s budget reports generally include estimates of the effect on the deficit (or
surplus) of selected policies not included in the baseline estimates. These policy
alternatives usually reflect policies under discussion or of high interest, such as
making the tax cuts permanent, addressing the expanding coverage of the AMT, or
assuming a rate of growth other than the inflation rate for discretionary spending. In
CBO’s January 2006 report, making the tax cuts permanent increases the five-year
(FY2007-FY2011) cumulative deficit (including higher debt-service costs) by $372
billion, and by a cumulative $2.3 trillion over the 10-year period (FY2007-FY2016).
CBO’s estimate of the revenue loss from reforming the AMT produces a $317 billion
five-year cumulative increase in the deficit and a $691 billion increase over 10 years.
If discretionary spending were to grow at the rate of GDP, rather than at the rate of
inflation, the five-year cumulative deficit would increase by an estimated $356
billion, and the 10-year cumulative deficit would increase by an estimated $1.6
trillion. Freezing discretionary appropriations at the FY2006 level would reduce the
five-year cumulative deficit by $317 billion and the 10-year cumulative deficit by
$1.4 trillion.
President Bush’s FY2007 budget called for extending and making permanent
most of the tax cuts adopted in 2001 and 2003, as well as extending other expiring
tax provisions. The budget showed extending the 2001 and 2003 tax cuts would
reduce receipts by an estimated $179 billion between FY2007 and FY2011, and by
an estimated $1.4 trillion between FY2007 and FY2016 (these estimates do not
include the resulting higher debt-service costs resulting from the change).2 The
2 The changes are measured from OMB’s current services estimates, its baseline, excluding

CRS-4
Administration’s total receipt proposals would reduce five-year receipts by $280
billion, and 10-year receipts by $1.7 trillion. Cumulative receipts over the 5- and 10-
year periods total approximately $13,823 billion and $32,496 billion respectively,
without the proposed changes.
The Administration’s budget provided a limited amount of information for the
years beyond FY2011. The budget did include estimates of the cumulative proposed
revenue changes and proposed mandatory spending changes for the periods FY2007
through FY2011, and FY2007 through FY2016, but these projections contained no
information for the individual years after FY2010. Nor were estimates provided for
other components of the budget or for budget totals beyond FY2011.
Although not included in the budget documents (it was made available on
February 9, 2006), the President proposed the elimination of, the reduction in, or the
reform of approximately 141 discretionary programs. The Administration reports
that these changes would produce an estimated $20 billion in budget authority (not
outlay) savings in FY2007 compared to FY2006. How much these savings would
affect the FY2007 deficit was left unclear.
The budget also proposed reductions (mostly in the rates of increase) in
mandatory programs over the next five years. The proposed net savings total $71
billion over five years, but this is only a partial accounting of the President’s
mandatory proposals. The other proposals include user fee increases ($3 billion in
savings), program “augmentations” ($9 billion in increases), Social Security personal
accounts ($82 billion in increases in FY2010 and FY2011), the outlay effects of
extending the tax cuts ($6 billion in increases), and other mandatory proposals ($1
billion in savings). The net effect increases mandatory outlays by $21 billion over
five years. Over the same five years, cumulative mandatory spending, excluding the
Administration’s proposals, totals an estimated $8,385 billion. The Administration’s
$21 billion proposed increase raises mandatory spending 0.3% above its baseline
estimates.
CBO released its analysis (with contributions from the Joint Committee on
Taxation) of the President’s budget proposal on March 15 (a preliminary analysis was
published on March 3). The analysis involved plugging the Administration’s policy
proposals into CBO’s underlying budget assumptions and budget estimating
methods. The results produced smaller deficits in FY2006 and FY2007 than the
President’s budget, but the deficits were larger than CBO’s baseline estimates (see
Table 1). CBO’s reestimates and the Administration’s deficits were similar for the
subsequent years through FY2011. (CBO extended its reestimates through FY2016,
showing the deficit, under the Administration’s policies, growing slightly as a
percentage of GDP from FY2012 through FY2016.)
2 (...continued)
the proposals assumed in its revenue baseline. OMB included the assumption that the tax
cuts would be extended in its baseline. This produces a current services revenue estimate
substantially smaller than CBO’s baseline revenue estimate, particularly in the second half
of the 10-year period.

CRS-5
Uncertainty in Budget Projections
All budget estimates and projections are inherently uncertain. Their dependence
on assumptions that are themselves subject to substantial variation over short time
periods makes budget estimates and projections susceptible to fairly rapid and
dramatic changes.3 Small changes in economic conditions, particularly the rate of
GDP growth (from those assumed in the estimates) can produce large changes in the
budget estimates. According to CBO, a persistent 0.1% increase in the real growth
rate of real GDP would reduce the deficit (including interest costs) by $58 billion
cumulatively over a five-year period and by $272 billion over the next 10 years.
Reductions in the rate of GDP growth would increase the deficit by similar amounts
over the same time periods. Policy changes that are likely, such as supplemental
appropriations for operations in Iraq and Afghanistan, but are not included in CBO’s
baseline, can also change the budget outlook, both for the current budget year and for
years in the future.
The President’s (FY2007) budget includes a chapter in the Analytical
Perspectives volume titled “Comparison of Actual to Estimated Totals.” The chapter
examines the causes of the changes from the initial budget estimates for FY2005
(February 2004) through the actual results for that year. OMB extends its analysis
to find upper and lower bounds to the deficit or surplus estimates over a five-year
period, based on data going back to FY1982. It found that the upper and lower
bounds range over $1.1 trillion at the end of a five-year period. In other words, the
Administration’s deficit estimate for FY2011, $205 billion, could range from a
surplus of approximately $300 billion to a deficit of approximately $700 billion (with
a 90% chance of the budget balance falling between those two numbers). Even the
Administration’s deficit estimate for FY2007 has a 90% chance of being as small as
$86 billion or as large as $622 billion.
Budget projections are dependent on the underlying assumptions about the
direction of the economy, expected policy and policy changes, and how these
interact, along with other factors (such as changing demographics) that affect the
budget. Any deviation from the assumptions used in the budget estimates, such as
faster or slower economic growth, higher or lower inflation, differences from the
expected or proposed spending and tax policies, or changes in the technical
components of the budget models can have substantial effects on the budget
estimates and projections, particularly over longer periods.
3 Some of the underlying components of budget estimates are known with some certainty.
Demographics are one known component. In the next decade, the expected retirements in
the baby boom generation will rapidly increase the spending for Medicare and Social
Security as well as other federal activities benefitting the elderly. Because virtually all those
who will become eligible for these benefits are alive today, estimating the growth in the
populations eligible for these programs is relatively straightforward.

CRS-6
Budget Action
Congressional committees began hearings on the President’s FY2007 budget
shortly after it was released. The Senate Budget Committee reported its version of
the congressional budget resolution for FY2007 (S.Con.Res. 83) on March 9. After
amending the resolution, the Senate passed it on March 16. As passed, the resolution
had higher outlays and deficit for FY2007 than proposed by the President, assumed
the extension of numerous expiring tax cuts (but did not include a fix, temporary or
otherwise, for the Alternative Minimum Tax beyond FY2006) without procedural
protections, and did not include reductions in mandatory spending. The House
Budget Committee passed its version of the FY2007 budget resolution (H.Con.Res.
376) on March 29. The House Budget Committee’s resolution has smaller
discretionary spending caps than the Senate-passed resolution, among other
differences. The House has not yet (as of April 20) considered the budget resolution.
Outlays
The Administration’s FY2007 budget proposes $2,770 billion in outlays for
FY2007, rising to $3,240 billion in FY2011, the last year shown in the President’s
budget. The proposals would boost funding for defense and homeland security
spending, restrain or cut most other discretionary spending, and make modest
growth-slowing changes to Medicare. In FY2010 and FY2011, it would raise
spending by tens of billions of dollars to fund private accounts for Social Security.
The Administration’s proposals, which the budget assumes are adopted, would raise
outlays by $61 billion (2.2%) above the Administration’s revised FY2006 outlay
estimate, and by 17.0% from FY2007 to FY2011.

CRS-7
Measured against the Administration’s FY2007 current services baseline outlay
estimates, the proposed level of outlays grows by $69 billion (2.6%).4 The difference
between the current services baseline outlay estimate and proposed outlays for
FY2007 indicates the “cost” of the Administration’s proposed policies. The year-to-
year change (the $61 billion increase) combines the “costs” of proposed policy
changes for FY2007 with the relatively automatic growth in large parts of the budget
from FY2006 to FY2007. These relatively automatic increases include cost-of-living
adjustments in many federal programs, growth in populations eligible for program
benefits, and inflation-driven costs of goods and services bought by the government.
From FY2006 to FY2007, the Administration’s budget makes a number of
assumptions, including the following: a $19 billion increase in undistributed
offsetting receipts (that reduce outlays) from proposed sales of a portion of the radio
spectrum; a reduction ($23 billion) in disaster and relief spending for hurricane relief
efforts that the Administration expects to wind down in FY2007; a $22 billion
reduction in federal education funding, mostly for support of higher education;
substantial increases in outlays in net interest ($27 billion), as both the debt and
interest rates rise; a rise in Social Security spending by an expected $31 billion; and
a rise in Medicare spending by an expected $49 billion, including the
Administration’s proposals to slow its growth.
As shares of gross domestic product (GDP), the Administration’s proposals
reduce outlays from 20.8% of GDP in FY2006 to 20.1% of GDP in FY2007. By
FY2011, the Administration projects that outlays will have fallen to 19.1% of GDP.
CBO’s January 2006 baseline estimates show outlays falling very slowly from 19.8%
of GDP in FY2007 to 19.4% of GDP in FY2011 and, after falling slightly in the
intervening years, returning to 19.4% of GDP in FY2016. Under a selection of
CBO’s alternative scenarios for spending — assuming there is a phase-down in
activities in Iraq and Afghanistan over a number of years, that total discretionary
spending increases at the rate of nominal GDP growth (rather than the rate of
inflation), and including higher interest costs from the larger deficits and debt
resulting from these changes (and from extending the tax cuts) — outlays would fall
from 20.1% of GDP in FY2007 to 20.0% of GDP in FY2011 before rising to 21.2%
of GDP in FY2016.
The President’s budget indicates that Department of Defense (DOD) spending
will increase by 6.9% from FY2006 to FY2007. This increase ($28 billion, from
$411 billion to $439 billion) is based on budget authority (BA) for those two years
and excludes enacted and proposed supplementals for the DOD. The President’s
budget shows outlays, the actual expenditures of the DOD, dropping from FY2006
4 The current services baseline estimates, like CBO’s baseline estimates, are designed to
provide “a neutral benchmark against which policy proposals can be measured.” For
outlays, the modified baseline used this year by OMB assumes emergencies are one-time
only, that federal pay adjustment assumptions reflect the (usual) January 1 start of inflation-
adjusted raises rather than October 1, and the debt service (interest payment) changes
resulting from these (and revenue-related) modifications are included in the baseline. These
modifications reduced the reported current services baseline outlay estimate by
approximately $45 billion in FY2007 and by $86 billion in FY2011.

CRS-8
($512 billion) to FY2007 ($505 billion), a 1.4% reduction in spending.5 (Total
outlays, not BA, and total revenues determine a year’s surplus or deficit.) With the
uncertainty surrounding the financing needs for the war on terror, FY2007 defense
outlays seem likely to change. CBO’s baseline estimates for defense spending
(which include extending supplemental funding) increase BA (by 2.5%) and lower
outlays (by less than 1%) between FY2006 and FY2007.6
Non-defense discretionary outlays in the President’s budget grow by just under
1% ($5 billion) from FY2006 to FY2007, from $500 billion in FY2006 to $505
billion in FY2007. The President’s budget shows non-defense discretionary BA
falling by 4.2% ($18 billion) between those two years. Most of that change results
from the boost in FY2006 spending from the Administration’s proposed $18 billion
hurricane relief supplemental. The Administration does not indicate a plan to repeat
that funding in FY2007. Excluding that amount, non-defense discretionary BA, as
a whole, barely changes from FY2006 to FY2007. CBO’s baseline non-defense
discretionary outlay estimates grow by less than 1% between FY2006 and FY2007,
from $499 billion to $502 billion, similar to the change in the President’s budget.
The President’s budget leaves unspecified his called for future year reductions in
discretionary spending.
Mandatory spending, federal activities that generally do not need an annual
appropriation, grows by 3.9% ($64 billion) from FY2006 to FY2007, including the
Administration’s proposed $1.7 billion in mandatory spending reductions for
FY2007.7 This raises mandatory spending, the largest category of federal spending,
from $1,457 billion in FY2006 to $1,494 billion in FY2007. CBO’s baseline
estimates of mandatory spending show it rising from $1,432 billion in FY2006 to
$1,488 billion in FY2007, a 3.9% increase.
The Administration proposed $36 billion in Medicare savings (from baseline
levels) through FY2011, which would slow, slightly, the expected increase in
Medicare spending. Medicare spending over the five years totals an estimated $2,207
billion. The Administration’s proposed Medicare reduction amounts to a 1.6% cut
from total Medicare baseline spending over the five years. The budget also included
in its mandatory proposals, personal accounts for Social Security (beginning in
FY2010) that would increase spending by $82 billion over the two years, FY2010
and FY2011. The net effect of the Administration’s mandatory proposals would
increase spending by $21 billion over the five years, FY2007 through FY2011.8
5 These outlay numbers include both discretionary and mandatory outlays for the DOD.
Mandatory spending for the DOD is less than $2 billion in both years.
6 CBO’s defense category matches the Budget Enforcement Act (BEA) defense category,
a somewhat larger collection of defense related activities than is covered by the DOD alone.
7 The Administration’s reductions include increased user fee offsets as well as reductions
in mandatory spending.
8 The mandatory proposals would increase spending by an estimated $551 billion from
FY2007 through FY2016, according to the budget documents.

The large deficits and rising interest rates have an effect on the interest
payments the government must make on its growing debt. Both the President’s
budget and CBO’s baseline estimates show net interest rising by 12% from FY2006
to FY2007. Continued large deficits

The slide in defense and non-defense
spending as a share of GDP after
2000 2002 2004 2006 2008 2010
FY2006 occurs in both the
Administration’s proposed and current service baseline estimates and projections.
The reductions depend on the Administration’s assumptions that non-defense, non-
homeland security discretionary spending falls by 1.6% annually (FY2007 through
FY2011) and that there is no additional funding for the war on terror after the $50
billion proposed for FY2007 (which means that DOD outlays fall by 0.6% a year).
The President proposed some reductions, from current service levels, in mandatory
spending, but they have little effect in changing mandatory spending as a share of
GDP. By FY2010 and FY2011, the President’s proposed private accounts for Social
Security raise mandatory spending as a percentage of GDP above the current services
level. Mandatory spending grows at an annual rate of 5.2% in the President’s budget.
Figure 2 shows three possible paths for outlays as percentages of GDP through
FY2016: the CBO baseline, the President’s proposal (as reestimated by CBO), and
an alternative estimate derived from CBO data. CBO’s baseline falls as a share of
GDP through FY2012 before beginning to rise. CBO’s reestimate of the President’s
proposed outlays fall sharply after FY2006, in part the result of the Administration’s
assumption of reductions in discretionary spending, before beginning a steady rise
after FY2012. Future outlays in both estimates remain below FY2006 estimated
outlays as a percentage of GDP. The third line, the alternative estimate, is based on
selected policy alternatives estimated by CBO that were not included in CBO’s
baseline. The alternative incorporates several assumptions. One, that discretionary
spending grows at the rate of nominal GDP growth (a higher rate of growth than used
in the baseline). Two, that instead of annually repeating the recent supplementals for

CRS-10
the war on terror and hurricane relief, funding for the military activities in Iraq and
Afghanistan are phased down over several years and hurricane relief ends after
FY2006. Three, that, because of larger deficits and debt, the government’s interest
costs are larger than in the baseline. And four, that, as in the baseline, mandatory
spending is expected to grow faster than GDP. The lower outlays resulting from the
change in the assumption about repeating the supplementals is overwhelmed by the
higher outlays resulting from the faster rate of discretionary spending and additional
interest costs. Outlays under the alternative estimate fall as a percentage of GDP in
the near future (from 20.1% of GDP in FY2007 to 19.9% of GDP in FY2012) before
rising fairly rapidly after FY2012 (from 19.9% of GDP in FY2012 to 21.2% of GDP
in FY2016).
The Senate-passed budget

years forecast in the President’s budget, revenues would rise from $2,416 billion in
FY2007 to $3,035 billion in FY2011, a 25.6% increase.
The Administration’s proposal to extend and make permanent many of the tax
cuts adopted in the Administration’s first term has little effect on FY2007 revenues.
Most of the budgetary effect of extending the tax cuts would occur after FY2010.
(Because the Administration incorporated the effect of making the tax cuts permanent
in both its proposed and current services baseline estimates, there is no upward bump
in receipts in FY2010 or FY2011. CBO’s baseline, which assumes the tax cuts
expire, shows a larger increase in receipts between FY2010 and FY2011 than in
earlier years. See Table 3.) The Administration estimated that making the 2001 and
2003 tax cuts permanent would reduce receipts by $179 billion between FY2007 and
FY2011 and by $1.4 trillion between FY2007 and FY2016. The effect of these
extensions and the Administration’s other proposals for receipts would reduce

CRS-11
receipts by $280 billion in the first five years and by $1,667 billion over 10 years.
CBO’s January 2006 budget report estimated that extending the expiring provisions
of the major tax cuts in 2001 and 2003 would reduce revenues by an estimated $346
billion over the first five years and by $1,606 billion over 10 years. Extending all the
tax cuts that expire over the 10-year period would reduce revenues (from CBO
baseline levels) by $582 billion in the first five years and by $2,644 billion over the
full 10 years of the forecast.9

CSB — The Administration’s current services baseline.
HBC — House Budget Committee
The estimated reductions in revenues from extending tax cuts do not reduce
year-to-year revenues. The Administration projected that receipts would rise from
$2,285 billion in FY2006, to $2,416 billion in FY2007, and to $3,035 billion in
FY2011 (including the effect of the Administration’s proposals). CBO’s revised
baseline estimates (March 2006) showed revenues increasing from an estimated
$2,312 billion in FY2006, to $2,461 billion in FY2007, to $3,139 billion in FY2011,
and to $4,114 billion in FY2016.

associated with larger deficits and debt) of the extensions.

(AMT) for fiscal years 2006 and
2007. Without further extensions of or a permanent fix to the AMT, a growing
number of middle-class taxpayers will find themselves subject to the AMT.10 CBO
estimates (January 2006) that providing annual AMT relief would reduce receipts by
$236 billion between FY2007 and FY2011, and by $437 billion between FY2007 and
FY2016. Without some adjustment to the AMT, it will eventually recapture much
of the tax reduction provided in the 2001 and 2003 tax cuts.11
As shares of GDP, total receipts are expected to remain near or below their
average of 18.2% (between FY1965 and FY2005) throughout the period covered in
the Administration’s budget. CBO’s estimates of the Administration’s proposals
showed receipts rising slowly from 17.6% of GDP in FY2007, to 17.8% of GDP in
FY2011, and to 18.2% of GDP in FY2016 (CBO extended the Administration’s
policies through FY2016). As one would expect, CBO’s revised baseline estimates,
which exclude the extension of the tax cuts, are larger, rising from 17.9% of GDP in

reaches 19.7% of GDP.12
Modifying CBO’s baseline revenue estimates and projections by using its
alternative policy estimates produces much slower growth in receipts, both in dollars
and as shares of GDP, than in CBO’s baseline.13 And although receipts still rise as
a percentage of GDP, they do so more slowly than in the President’s proposal and
much more slowly than in CBO’s baseline. By FY2011, the alternative estimates of
receipts would rise to $2,925 billion, or 17.4% of GDP. By FY2016, the alternative
estimated receipts rise to $3,740
billion, or 17.9% of GDP. This is

ends in FY2011 when the

CBO does not. CBO’s revised baseline shows a big jump in receipts in FY2011, as
its assumptions include the tax increases resulting from the expiration of the 2001
and 2003 tax cuts. CBO’s reestimates of the President’s tax proposals assumes that
the tax cuts are made permanent. Both the reestimates and the alternative estimates
in Figure 4 follow similar paths, although at different levels of GDP, after FY2010.
The alternative estimates show receipts staying between 17.5% and 17.9% of GDP
throughout the 10-year period.
12 The CBO baseline incorporates the assumption of a substantial tax increase after FY2010
when the large 2001 and 2003 tax cuts expire under current law.
13 CBO indicates that combining the reform of the AMT and the tax extenders produces an
interactive effect that makes the combined loss greater than the sum of the two estimates
separately.

The Senate-passed budget resolution accommodated over $200 billion in

Deficits (and Surpluses)
Deficits and surpluses are the residuals left after Congress and the President set
policies for spending and receipts. Surpluses, in which receipts are greater than
outlays, reduce federal debt held by the public, which can lead to lower net interest
payments (among other effects). Deficits, in which outlays exceed receipts, increase
government debt held by the public, generally increasing net interest payments. The
government had its last surplus in FY2001 ($128 billion and 1.3% of GDP).

a. Actual deficit for FY2005.
CSB — The Administration’s current services baseline.
The President’s budget proposed a FY2007 deficit of $354 billion (2.6% of
GDP). The Administration’s budget showed the deficit shrinking in dollars and as
a share of GDP through FY2010 before rising slightly in FY2011. Without policy
changes, the deficit is likely to begin rising in subsequent years as the baby boom
generation retires in large numbers and raises the demand for federal spending on the
elderly, even as revenues remain near or below historical levels.
The Administration asserts that the FY2007 budget will further the President’s
oft-repeated goal of cutting the deficit in half by FY2009. To achieve this goal, the
Administration reaches back to its February 2004 deficit estimate for FY2004 ( 4.5%
of GDP) as the starting point, and the time when it first articulated this goal.14 The
FY2007 budget shows the deficit falling below 2% of GDP by FY2008 and to 1.4%
of GDP in FY2009. The goal may be difficult to reach if Congress does not fully
adopt the Administration’s proposals, if additional AMT relief is implemented
beyond FY2007, if additional defense supplementals for the war on terror are adopted
after FY2007, or if any number of budget-related events occur over the next several
years that raise outlays or reduce receipts.
14 The actual deficit for FY2005 was 2.6% of GDP. Since 2002, the Administration has
consistently overestimated the size of the current or the next year’s deficit in each year’s
budget.

CRS-15
Achieving the Administration’s deficit reduction goals would require, during the
next five years, strict limits on the growth in domestic discretionary spending (if not
actual reductions), a slowing in the

remaining years of the forecast. The
requirements and assumptions that
CBO must follow in producing the baseline estimates accounts for almost all of this
improvement in the deficit/surplus outlook. Under a selection of alternative policies
not included in the baseline (as shown in CBO’s January 2006 budget report) that
may better forecast the future path of fiscal policy, the deficit does not shrink and
become a surplus. Instead, it grows throughout the 10-year period in dollars and,
after FY2012, grows as a share of GDP (see the CBO-based alternative estimate in
Figure 5).
Figure 5 shows deficit estimates as shares of GDP for FY2000 through
FY2016.16 The actual amounts for the surpluses and deficits are shown for FY2000
through FY2005. Subsequent years are based on data from the CBO’s January 2006
and March 2006 budget reports. The CBO baseline deficit estimate assumes the
expiration of the 2001 and 2003 tax cuts in 2010, no future adjustments to lessen the
expanding coverage of the AMT, the adjustment of discretionary spending for
inflation, and an annual repetition of the 2005 funding supplemental for the military
activities in Iraq and Afghanistan and hurricane relief efforts. The result of these
15 The Administration’s current services baseline estimate, which assumes current policy,
has smaller deficits throughout the five-year period than the deficits in the President’s
proposed budget. The cumulative five-year deficit would be smaller without the President’s
proposed policy changes than with them.
16 Note that in the chart, larger deficits are at the top; smaller deficits or larger surpluses are
towards the bottom.

CRS-16
baseline assumptions, as percentages of GDP, is growing receipts, falling outlays,
and a rapid fall in the deficit as a share of GDP, reaching a surplus in FY2012. The
CBO estimate of the President’s policy proposals assumes additional spending for
defense in FY2006 and FY2007, additional hurricane relief in FY2006, very tight
controls on domestic discretionary spending, a slight slowing in the growth of
Medicare, and the creation of personal accounts for Social Security in FY2010 and
FY2011. The result is an upward bump in the deficit in FY2006, and a fall until
FY2012, after which the deficit remains near 1% of GDP through FY2016.
The alternative estimate in Figure 5 used selected estimates of alternative
policies estimated by CBO (that reflect faster discretionary spending growth,
extending the expiring tax cuts, retaining relief from the AMT, and incorporating
increased debt servicing costs). Under these assumptions, the deficit estimates, after
an upward bump in FY2006, fall slightly through FY2012. At that time, deficits
grow fairly rapidly as revenues fall (as a percentage of GDP) and outlays continue
growing (as a percentage of GDP).
The Senate budget resolution contains a slightly larger deficit in FY2007 than
in the President’s budget and is almost $30 billion larger than CBO’s reestimate of
the President’s proposed deficit. Compared with CBO’s revised baseline, the
Senate’s budget resolution deficit is almost $100 billion larger. As shares of GDP,
the deficits in the Senate budget resolution fall from 2.6% in FY2007 to 1.0% of
GDP in FY2010 before rising to 1.1% of GDP in FY2011.
The Longer Run
Both OMB and CBO agree that over a longer time period, one beginning in the
next decade and lasting for decades, demographic pressure will so badly distort
current policies as to make them unsustainable. The future, under current policies,
will lead to growing and persistent deficits. A CBO report on The Long-Term Budget
Outlook
(December 2005) states
Over the next half-century, the United States will confront the challenge of
conducting its fiscal policy in the face of the retirement of the baby-boom
generation.... Under current policies, the aging of the population is likely to
combine with rapidly rising health care costs to create an ever-growing demand
for resources to finance federal spending for mandatory programs, such as
Medicare, Medicaid, and Social Security.... [A]ttaining fiscal stability in the
coming decades will probably require substantial reductions in the projected
growth of spending and perhaps also a sizable increase in taxes as a share of the
economy.17
The Administration indicated similar concerns about the outlook for the budget
over the long term in the President’s FY2007 budget (February 2006).
...the long-term picture presents a major challenge due to the expected growth in
spending for major entitlement programs. In only two years, the leading edge of
17 CBO, The Long-Term Budget Outlook, Dec., 2005, p.1.

CRS-17
the baby boom generation will become eligible for early retirement under Social
Security. In 5 years, these retirees will be eligible for Medicare. The budgetary
effects ... will be muted at first. But if we do not take action soon to reform both
Social Security and Medicare, the coming demographic bulge will drive Federal
spending to unprecedented levels and threaten the Nation’s future prosperity.
No plausible amount of cuts to discretionary programs or tax increases can help
us avert this major fiscal challenge.... By 2070, if we do not reform entitlement
programs to slow their growth, the rate of taxation on the overall economy would
need to be more than doubled....18
The short-term budget outlook can change when it is buffeted by all types of
unexpected events, such as the hurricanes last year or deteriorating economic
conditions. The long-term budget outlook, although susceptible to these types of
events, will largely be determined by the interplay of current policy and
demographics. The retirement of the baby boom generation, rapidly expanding the
population eligible for federal programs serving the elderly, will put enormous
pressure on the federal budget. Without policy changes, these programs could
overwhelm the rest of the budget. Not only will the programs themselves be stressed,
but their growth would be likely to impede the government’s ability to meet its
obligations and the ability of the economy to provide the resources needed.
