In March of this year, the Congressional Budget Office projected that large deficits in 2003 and 2004 would be followed by falling deficits thereafter, a budget surplus within five years, and large and growing surpluses within ten years.  Even accounting for the recently enacted tax cuts and supplemental appropriations to fund the Iraq war, CBO’s projections imply steadily improving budgets.  But such a conclusion would be considerably too optimistic: CBO’s figures omit as much as $4.3 trillion in costs over the next ten years, costs that result from legislation that Congress is likely — and in many cases, virtually certain — to enact.  With these extra costs, the deficit over the ten year from 2004 through 2013 would total $4.1 trillion.

If the tax cuts are extended and other likely costs occur, deficits will total $4.1 trillion over the next ten years, will never fall below $325 billion in any year, and will reach $530 billion by 2013.

A deficit of 3.0 percent of GDP at a time when the retirement of the vast bulk of the baby-boom generation is just starting is a prescription for severe fiscal distress in the following decades.  When the baby boom generation retires over the course of the next few decades, the costs of Medicare, Medicaid, and Social Security will grow quite substantially as a share of GDP, while the revenues needed to support these programs will not.  The best way to prepare for the extra costs of these programs would be to reduce or eliminate the debt during this decade and thereby reduce or eliminate interest costs.  Saving for the future — and shrinking the debt constitutes saving for the future — would offset a portion of the inevitable cost increases in Medicare, Medicaid, and Social Security, and thereby partly relieve the pressure to cut these programs, to cut other federal programs, or to raise taxes.  Yet debt and interest costs are now on track to rise rather than fall; instead of preparing for the future by putting our finances in order before the baby boomers retire, we are going deeper into debt, and at just the wrong time.  It is perhaps for this reason that Goldman Sachs calls the nation’s long-term budget outlook “terrible, far worse than the official projections suggest.”[3]


The CBO Baseline and What It Does Not Include

 The most recent CBO baseline projection was issued in March, 2003, and showed deficits through 2006 but surpluses thereafter.  Over the ten-year period from 2004 through 2013, CBO’s March baseline projected a net surplus of $890 billion.  Unfortunately, this figure of $0.9 trillion in surpluses is both out of date and a poor predictor of likely future budget results.

Since publication of CBO’s March baseline, Congress has enacted a new tax cut officially scored as costing $350 billion through 2013, supplemental appropriations that fund this years’ cost of the Iraq war, and a seven-month extension of the Temporary Emergency Unemployment Compensation program.  In addition, CBO has reported that revenues for 2003 are already falling well below expectations and are likely to end up $50 billion to $80 billion below the level CBO projected in March 2003, even before accounting for the new tax cut.  Even if one considers all of these costs to be temporary  and assumes all of the new tax cuts will end on their artificial “sunset” dates, these costs plus interest on them reduce the projected 2004-2013 surplus from $0.9 trillion to about $0.2 trillion.  (See Table 1.)

   less: cost of Iraq supplemental appropriations to date.



   less: possible revenue shortfalls in 2004 and 2005.



   less: extra interest payments on extra borrowing to finance above items.



Projected net surplus based on actions to date



NOTES: Each of the listed items also results in costs in 2003; for example, the tax cut costs $61 billion in 2003, so that its total cost through 2013 is $350 billion.  The large amount of 2003 costs explains the large amount of extra interest payments shown above.  CBO estimates that 2003 revenues will fall short of expectations by $50 billion to $80 billion in 2003; this analysis conservatively uses the $50 billion figure and also assumes that these revenue shortfalls will only persist in mild form after 2003.  The House Budget Committee Democratic staff, in contrast, estimates that the 2003 revenue shortfalls could presage as much as $0.5 trillion in revenue shortfalls over the next decade.

CBO baseline estimates are a projection of future expenditures and revenues that are calculated according to a set of rules that are based on current law and thus assume, among other things, that all tax cuts scheduled to expire will indeed terminate on schedule, even when such tax measures are routinely renewed.  These projections are the basic benchmark against which analysts assess the costs of proposed and actual changes in policy.  These projections do not necessarily provide a realistic assessment of the future fiscal outlook, however, and are not intended to do so.  Because they are based on these rules, the new CBO projections present a far rosier picture of the future than is likely to occur.

The CBO projections are unrealistically rosy for a number of reasons: they omit the cost of extending tax breaks that are scheduled to expire but that Congress always renews, as well as the costs of extending the 2001 and 2003 tax cuts beyond their scheduled expiration dates and providing relief from the mushrooming alternative minimum tax; they understate the costs of appropriated programs, especially for defense, Iraq occupation, and homeland security; they do not include any costs of a Medicare prescription drug benefit; and they do not include the costs of responding to major natural disasters such as hurricanes or floods.  Table 2, on the next page, summarizes the omitted costs that are likely, and in some cases virtually certain, to occur over the next decade.

* Note: In the case of a possible occupation of Iraq, the future situation is highly uncertain; we show costs ranging from zero to $3 billion per month for ten years.  For purposes of calculating a total, we use the mid-point of the range.  See discussion below.  All costs are rounded to the nearest $10 billion, then added.

Combining the $145 billion in extra costs from the extension of routine expiring tax breaks, the $610 billion in extra costs from the extension after 2010 of the 2001 tax-cut law, and the $710 billion in extra costs from the removal of artificial sunsets from the new tax cut results in a total of almost $1.5 trillion in additional revenue losses.  With interest, such extensions would add $1.7 trillion to the 10-year deficit, as shown in Table 2 on the prior page.

Other Analyses Produce Similar Results

Other analysts also conclude that the CBO baseline should not be used to infer likely future surpluses.  Making adjustments similar to those in this analysis, others find deficits of:

  • $4.0 trillion over ten years: Peter G. Peterson (President of Concord Coalition), April 30, 2003.
  • $4.0 trillion over ten years, $476 billion in 2013: Rep. John Spratt, Ranking Member, House Budget Committee, May 29, 2003.
  • $4.1 trillion over ten years, $530 billion in 2013: this analysis.
  • $500-$575 billion in 2013: Committee on Economic Development, March 2003.

The list of items not included in the CBO baseline thus is both lengthy and costly.  Counting interest, it exceeds $4.3 trillion over the decade (see table 2 on page 5).  With the exception of a Medicare prescription drug benefit, the $4.3 trillion in additional costs can be viewed as representing tax and program policies that are in place today but that CBO does not include in its baseline for technical reasons.  In the past, when the significance of expirations in the tax code was trivial, the baseline functioned both as a benchmark against which to measure the cost of legislation and as a plausible predictor of future deficits.  Now it no longer does the latter.  As former CBO Director (and current Urban Institute President) Robert Reischauer remarked, “Rarely have the policies underlying the baseline projections been as disconnected from the policy makers’ agendas as they are today.”

While it is possible that some fraction of the $4.3 trillion in costs in Table 2 might be avoided, it should also be noted that some of these estimates are conservative.  For example, if a prescription drug benefit of the type currently under discussion is enacted, the pressure to expand the benefit to cover a higher share of the costs of drugs may become immense.  Moreover, the Administration and the Congressional Leadership intend to enact additional tax cuts not reflected in our analysis.


How Much is $530 Billion?

Table 2 shows that if the costs not included in CBO’s baseline are incurred, the budget deficit will reach $530 billion in 2013 alone.  Figures of that magnitude are often hard to comprehend; this section attempts to put that figure in context.

To start with, $530 billion in 2013 equals 3.0 percent of GDP in that year.  In today’s terms, 3.0 percent of GDP is $324 billion.  That amount, $324 billion, equals:


Squandering the Opportunity to Reduce Debt and Failing to Prepare for the “Age Wave”

To prepare for the imminent retirement of the baby boom generation, the nation should decrease the national debt, not increase it.  During the 1990s, debt held by the public fell from 49.5 percent of the Gross Domestic Product in 1993 to 33.1 percent by 2001.  This analysis finds that deficits will total $4.1 trillion over the period 2004-2013 if the costs not included in CBO’s projections are incurred; if so, the debt will grow to almost 46 percent of GDP by 2013 and higher levels in years after that.

It is widely understood that when the “age wave” hits — when the baby boom generation starts to retire in 2008 — the costs of Medicare, Medicaid, and Social Security will grow faster than the economy, i.e., faster than the tax base.  Over the course of the two subsequent decades, the gap between the cost of these three programs and the revenue needed to support them will widen substantially.  To address this funding gap, the nation will have no choice but to raise revenues, reduce the benefits provided by these or other programs, or both.  The best way to reduce the magnitude of this impending budget problem is to reduce or eliminate debt during this decade, in advance of the baby boomers retirement.  Here is why.

By substantially decreasing debt during this decade, the government would avoid hundreds of billions of dollars per year in interest payments in all future years.  Instead of using a few hundred billion per year in revenues to pay interest, those same revenues could be used to cover some of the growing costs of Medicare, Medicaid, and Social Security.  Stated differently, budget pressures will grow from 2008 on and will ultimately force large tax increases, major benefit cuts in these programs, deep cuts in other federal programs, or some combination of these approaches.  By shrinking the debt during this decade, we would directly cut the cost of one of the largest of the “other” federal programs — interest payments on the debt.  These interest savings would reduce the degree to which the nation will in the future need to raise taxes or reduce benefits provided by Medicare, Medicaid, Social Security, or the rest of the government.  In short, the best way to protect future generations is to run surpluses, not deficits, in the present, once the economy recovers.[9]

In March of this year, CBO projected that interest payments would fall from 2.1 percent of GDP in 2001 to 1.0 percent by 2013.  Under the assumptions of this analysis, however —  with tax cuts extended beyond their scheduled expirations dates, defense plans fully funded, a prescription drug benefit enacted, and none of these policies paid for — interest costs would increase by $1 trillion and total $3.1 trillion over the ten-year period (rather than the $2.1 trillion projected by CBO in March).  The cost of interest would rise rather than fall, reaching $425 billion — or 2.4 percent of GDP — in 2013 alone.



CBO’s March 2003 assessment of the budget situation looked disturbing in the short run but noticeably better over the coming decade (followed eventually by serious shortfalls in the government’s ability to cover the costs of existing commitments).  A more realistic view of the budget suggests that even CBO’s relatively benign March projection is far too optimistic, unless Congress and the Administration reverse course and determine that program increases and new tax cuts (including the extension of existing, officially temporary tax cuts) must be paid for.  Acting now to reduce future deficits will make the burden imposed on future generations noticeably smaller than if we wait five, ten, or more years to act.

Appendix: AMT Relief

The recent tax-cut legislation includes a provision to protect taxpayers from the swelling Alternative Minimum Tax, but only through 2004.  The Administration had requested AMT relief in its budget, but only through 2005.  The New York Times recently quoted Pamela Olson, Assistant Secretary of the Treasury for Tax Policy, as stating that the Administration plans to propose a long-term solution to the AMT, but not until President Bush’s second term.  The article reported, “The target date [for a longer-term AMT proposal] is 2005, she said.  ‘We are working on it,’ Ms. Olson said.” [10]  Although addressing the AMT problem is clearly part of Administration and congressional plans, the costs of doing so beyond 2004 are not reflected in the new tax law.

Source of the AMT Problem

The Alternative Minimum Tax is a parallel tax system originally designed to ensure that tax filers with high incomes could not avoid paying taxes altogether by aggressively using available deductions, exemptions, and tax shelters.  Such taxpayers calculate their tax liability according to both the regular income tax and the AMT and pay whichever amount is higher.

Unlike the regular income tax code, however, the key components of the AMT are not indexed for inflation.  As a result, as incomes rise over time to reflect the effects of inflation, more taxpayers become subject to the AMT.  This problem was exacerbated by the tax cuts enacted in 2001, which reduced tax liabilities under the regular income tax code, particularly for those with high incomes, without making corresponding adjustments in the AMT.

About two and one-half million taxpayers are currently subject to the AMT.  The Tax Policy Center estimates that the number of taxpayers subject to the AMT will soar to more than 41 million by 2013, assuming that the 2001 tax cuts are made permanent, and the Treasury has issued estimates that corroborate this finding.  The AMT would hit one of every three taxpayers in the nation by that year, with many middle-class families finding themselves subject to it and its complexities.  By that time, the AMT would be “taking back” a goodly share of the 2001 tax cut from many of these families, and more revenue would be collected under the AMT than the regular income tax.  It is inconceivable the President or the Congressional leadership of either party will allow the AMT to mushroom in this manner.

High Cost of AMT Relief

Revenue-Neutral AMT Relief?

The Tax Policy Center has designed an option to provide AMT relief by restructuring the AMT in a cost-neutral manner; this option would free large numbers of middle-class taxpayers from the AMT and offset the cost by making the AMT tougher on high-income taxpayers (especially taxpayers with very high incomes, who currently are generally not affected by the AMT).  There is virtually no chance the Administration will propose such a cost-neutral approach, even though the large, growing, and permanent deficits the nation faces suggests that all future tax cuts should be offset.

Preventing the individual Alternative Minimum Tax from exploding in size and encroaching heavily upon middle-class taxpayers in the years to come could be very costly.  Because current law only provides AMT relief through 2004, however, the apparent cost of making the 2001 tax cuts permanent is kept down, since the official estimates rest upon the unrealistic assumption that AMT relief will end after 2004, the number of taxpayers subject to the AMT will explode after that year as a result, and the swollen AMT will cancel out a sizeable share of the tax cuts.  This enables the Administration to show the cost of making the tax cut permanent as being much lower than that cost actually will be.

In reality, of course, AMT relief will be continued beyond 2004.  The Bush Administration clearly intends to propose that such relief be maintained.[11]  The cost of extending AMT relief beyond 2004 thus is essentially an "off-book liability" that must be considered part of the long-term cost of any proposal to make the 2001 tax cut permanent.  It is necessary to include the cost of addressing the AMT problem when assessing the long-term cost implications of congressional or Administration tax-cut proposals.

The Urban Institute - Brookings Institution Tax Policy Center has undertaken the most thorough review of the AMT issue to date.[12]  Based on the Tax Policy Center analysis and recent estimates the Tax Policy Center has prepared, the loss in revenue from extending beyond 2004 the approach to AMT relief that is now in law would equal approximately $640 billion through 2013, and result in a total cost of about $760 billion when increased interest payments on the debt are taken into account.[13]

[11] The new tax-cut law’s temporary AMT relief builds on and expands a similar provision in the 2001 tax-cut package that also provided AMT relief through 2004.  The cost of providing permanent AMT relief would have driven the cost of the 2001 tax-cut package well above what the fiscal year 2002 Congressional budget resolution allowed, unless other elements of that package were scaled back.  The framers of the 2001 tax cut consequently resorted to the gimmick of letting the AMT relief sunset at the end of 2004, knowing that Congress would have no choice but to extend AMT relief before the provision expired.  This scenario occurred again this year, when AMT relief for 2004 was increased but AMT relief after 2004 could not be squeezed into the Senate’s informal $350 billion target for the newly enacted tax cut.

[13] This estimate reflects an AMT option that would hold the share of AMT filers at approximately 2 percent of all tax filers (the 2004 share), according to the Tax Policy Center.  We chose this AMT approach as consistent with the Congressional approach to the AMT; each of the temporary increases in the AMT exemption proposed in the various versions of this year’s tax cut would have kept the share of AMT filers at about this percentage in the two or three years that the increased exemption would be in effect.  (The estimate is based on the assumption that the 2001 tax cut will be made permanent rather than expire in 2010.)  Specifically, under this approach, we assumed the permanent extension of the treatment of non-refundable tax credits as a “preference” for purposes of the AMT, and also assumed that the AMT exemption amount would be increased to $60,000 for married couples in 2005, $70,000 in 2008, and $80,000 in 2013.  (The exemption amount for single filers and heads of households would continue to be 75 percent of the amount for married filers in all years, as under current law.)
