CRS Reviews History of 2001 Tax Cuts, Extensions

This report traces the legislative history of the Economic Growth and Tax Relief Reconciliation Act of 2001 (EGTRRA; P.L. 107-16) and its extensions, shows their time line, and provides general overview of their implications and revenue effects. The report focuses on the measures that extend or curtail the key tax relief provisions of EGTRRA and the follow-up legislation, rather than modify the respective parts of the tax code in some new way. Many aspects of the tax cuts, such as revenue feedback effects, have been discussed at length elsewhere, including other CRS reports referenced in the text, therefore the details of many issues are beyond the scope of this report.

President Bush has advanced the idea of the across-the-board tax cuts as one of the cornerstones of his economic policy since his first presidential campaign. EGTRRA provided such relief, but all of the act's provisions are scheduled to sunset (revert to prior law levels) at the end of 2010. Thus, Congress faces the issue of whether to let the tax cuts expire or extend them, and if so, how.

In 2001, EGTRRA reduced marginal income tax rates, provided marriage tax penalty relief, provided temporary relief from the alternative minimum tax (AMT), and increased the child tax credit. The Jobs and Growth Tax Relief Reconciliation Act of 2003 (P.L. 108-27) accelerated the implementation of certain tax reductions that were being phased-in under the 2001 act. The 2003 act also reduced the tax rate on dividend and long-term capital gains income, effective through 2008. The Working Family Tax Relief Act of 2004 (P.L. 108-311) extended many of the EGTRRA and JGTRRA provisions scheduled to expire at the end of 2004. The Tax Increase Prevention and Reconciliation Act of 2005 (P.L. 109-222) extended the capital gains and dividend tax reduction through 2010 and the AMT relief for one year.

Additional tax reductions and extensions to these tax acts were included in the Job Creation and Worker Assistance Act of 2002 (P.L. 107-147), the Tax Relief and Health Care Act of 2006 (P.L. 109-432), and Tax Increase Prevention Act of 2007 (P.L. 110-166).

A number of bills, many of them listed in the body of the report, have been introduced to extend all or some of the provisions of these acts. Notably, S.Con.Res. 70, adopted by the Senate on March 14, 2008, included AMT relief and an amendment (S.Amdt. 4160) by Senator Max Baucus that would provide more than $300 billion in middle class tax relief. The corresponding House measure (H.Con.Res. 312) does not include similar language, except for the extension of the AMT relief.

This report, which includes significant contributions from Gregg Esenwein, now retired from CRS, will be updated to reflect legislative activity.

All of the changes in EGTRRA were temporary, expiring after 2010 or earlier. Congress included the sunset in EGTRRA to avoid a Byrd rule (Section 313 of the 1974 Congressional Budget Act, as amended) violation in the Senate. The Byrd rule prohibits "extraneous matter" in reconciliation legislation.² Under the rule, extraneous matter includes, among other things, language that would cause an increase in the budget deficit (or reduce budget surpluses) in a fiscal year beyond those covered by the reconciliation legislation. As a result of the Byrd rule, EGTRRA contained language providing for the expiration of all of its provisions at the end of calendar year 2010 -- the end of the reconciliation budget window.

In 2003, Congress passed the Jobs and Growth Tax Relief Reconciliation Act (JGTRRA; P.L. 108-27). JGTRRA accelerated the implementation of many of the provisions that were being phased in under EGTRRA, including marriage-tax penalty relief, expansion of the 10% tax bracket, and increases in the child tax credit to $1,000 per qualifying child. The 2003 act also included an increase in the AMT exemption (a so-called "AMT patch"). These JGTRRA changes were scheduled to be in effect for only two years, 2003 and 2004.

In addition, JGTRRA lowered the maximum tax rate on qualified dividend income and long-term capital-gains income to 15% (5% for taxpayers in the 10% and 15% marginal income-tax brackets, dropping to 0% for these taxpayers in 2008). As originally enacted, these changes were effective through January 1, 2009. The estimated cost of JGTRRA's tax reduction provisions was $329.7 billion over the FY2003-FY2013 period.³

The American Jobs Creation Act of 2004 (AJCA; P.L. 108-357), among other things, contained a provision which allowed taxpayers to take an itemized deduction for state and local general sales taxes in lieu of the itemized deduction for state and local income taxes. This provision was to be in effect for two years, 2004 and 2005, at the cost of $3.6 billion.⁴

In 2004, Congress also passed the Working Families Tax Relief Act of 2004 (WFTRA; P.L. 108-311). WFTRA extended several tax provisions that were set to expire at the end of 2004 under JGTRRA.

WFTRA extended the accelerated marriage-penalty tax relief provisions (the standard deduction and 15% tax bracket for joint returns set at twice the level as those for single returns) through 2008. In 2009 and 2010, this level of tax relief would be maintained due to the full phase-in of the corresponding provisions of EGTRRA. The 2004 act also extended the increase in the 10% income-tax bracket through 2010.

WFTRA maintained the child tax credit at $1,000 through 2009 (for 2010, the EGTRRA provisions apply and the child tax credit will remain at $1,000). In addition, WFTRA accelerated, to 2004, the increase in the refundability of the child tax credit. For 2004 through 2010, the child tax credit will be refundable to 15% of a taxpayer's earned income in excess of the applicable threshold. The 2004 act also allowed including combat pay in earned income for purposes of computing child-tax-credit refundability.⁵

WFTRA included a one-year extension in the increase in the basic exemption for the alternative minimum tax (AMT) originally enacted under JGTRRA. (EGTRRA also included a temporary increase in the AMT exemption which was then superseded by the JGTRRA increases.) The AMT exemption for 2005 was set at $58,000 for joint returns and $40,250 for unmarried taxpayers.

In total, the WFTRA provisions were estimated to cost $131.4 billion over the FY2005-FY2014 time period.⁶

The Tax Increase Prevention and Reconciliation Act of 2005 (P.L. 109-222; TIPRA), passed by Congress in May 2006, extended the dividend and capital gains tax reductions through 2010. These reductions were enacted in 2003 and originally scheduled to expire in 2008. The estimated cost of these extensions was $50.8 billion over the FY2006-FY2015 period.⁷

For 2006, TIPRA also increased the basic AMT exemption to $62,550 for joint returns and to $42,500 for unmarried taxpayers. In addition, TIPRA extended through 2006 the provision that allows taxpayers to apply their non-refundable tax credits against their AMT tax liability. The combined cost of these AMT provisions is $33.9 billion.⁸ These temporary increases in the basic exemption for the AMT and changes in the treatment of non-refundable tax credits were once again enacted as a means of mitigating the interaction between the reductions in the regular income tax and the AMT. In 2007, the AMT exemption reverted to its pre-EGTRRA-law levels of $45,000 for joint returns and $33,750 for unmarried taxpayers.

The Tax Increase Prevention Act of 2007 (P.L. 110-166; TIPA), passed by Congress in December 2007, extended the AMT tax relief retroactively for one year at a cost of $50.6 billion.⁹ TIPA set the 2007 AMT exemption levels at $66,250 for joint returns and $44,350 for single returns. In addition, this bill allowed nonrefundable personal tax credits to offset AMT tax liability for 2007.

Additional broad tax reductions or extensions were enacted in the same time frame as parts of the other acts: the Job Creation and Worker Assistance Act of 2002 (JCWAA; P.L. 107-147) and the Tax Relief and Health Care Act of 2006 (TRHCA; P.L. 109-432). JCWAA's provisions modified depreciation rules at the cost of $17.9 billion over FY2002-FY2012.¹⁰ TRHCA extended the sales tax deductibility provision for tax years 2006 and 2007. The Joint Committee on Taxation estimated that the two-year extension of this provision would reduce federal revenues by approximately $5.5 billion.¹¹

The phase-in and expiration schedules of the various tax provisions enacted under the 2001 through 2007 tax acts are shown in the Appendix.

In contrast, the corresponding House measure (H.Con.Res. 312), adopted on March 13, 2008, only includes an AMT patch. Unlike in the Senate bill, the patch is offset in the House bill.

Extending the Cuts Past 2010: Key Considerations

Proposals relating to the future of the 2001-2007 tax reductions range from their early recision to unconditional permanent extension. Several aspects of this decision play a key role in shaping the views of many policymakers. They include (1) general desirability of providing tax relief, (2) the cost of the cuts in view of the budgetary constraints, and (3) the distribution of the tax cuts' benefits among different income groups of taxpayers.

In addition, the extension of the tax cuts is intertwined with modifying the AMT. In general, a taxpayer pays either the AMT or regular tax, whichever is higher. Thus, absent congressional action, the AMT will "take back" most of the tax relief granted through the regular income tax, as the AMT becomes higher than ordinary tax for many taxpayers.¹² Hence, Congress faces not only the issue of whether or not to extend or make permanent the reductions in the regular income tax, but it must face the issue of how to coordinate the changes in these two parallel tax systems.¹³

Modifying the AMT is probably the most pressing individual income tax issue currently facing Congress. It is estimated that, if the reductions in the individual income tax are extended beyond 2010, the number of taxpayers subject to the AMT will increase from over 1 million in 2001 to about 26 million in 2008, and then to almost 51 million in 2017.¹⁴

It is difficult to generalize about the economic effects of the 2001-2007 tax cut provisions due to their diverse nature, but economic theory suggests that some of them (for example, lower marginal tax rates) are likely to reduce economic distortions -- undesirable changes in behavior of economic agents resulting from imposing a tax. Thus, policymakers will weigh the benefits of tax reduction measures against their budgetary costs and other consequences. Ultimately, the conclusion would depend on many factors: specifics of provisions, time horizon, financing method, to name just a few. Detailed analysis of this issue, however, goes beyond the scope of this paper.¹⁵ In addition, tax reductions might be attractive for political or other reasons unrelated directly to economic performance.

Counterbalancing the desire to provide continued tax relief is the concern over the current and projected size of the federal budget deficit. The revenue effects of extending or making permanent the tax reductions would be substantial. Moreover, once the costs of fixing the AMT are included, the revenue costs associated with maintaining the current level of tax relief increase considerably.

For instance, Table 1 presents Congressional Budget Office (CBO) estimates of the cost of extending the EGTRRA and JGTRRA tax reductions and reforming the AMT.¹⁶ In addition to the direct costs of these policy options, the table also presents associated debt service costs -- indirect costs, which would arise if these policies are deficit financed (that is, if there are no offsetting tax increases or spending reductions). Due to strong interactive effects among various tax provisions and other assumptions, these numbers should be treated as order-of-magnitude estimates.

According to Table 1, the estimated total cost of extending the EGTRRA and JGTRRA tax cuts, reforming the AMT, and servicing related debt would be $4.3 trillion over the FY2009-FY2018 period, but only $1.3 trillion over the first five years of this period. The projected cost of the second five years would be almost 2 1/2 times that of the first five.

 Table 1. Estimates Illustrating the Revenue Costs Associated

 Table 2. Annual Projected Cost of Extending the Tax Cuts

CBO analysis indicates that extending the individual income tax portion of the 2001-2007 tax cuts without providing AMT relief past 2007 would result in 0.7% additional fiscal gap, yielding the total fiscal gap of 2.4% of GDP. Assuming AMT relief measures are extended at 2007 levels and then indexed for inflation, the reduction in revenue would double the incremental fiscal gap to 1.4%, leading to 3.1% total. Finally, adding the extension of the estate and gift tax reductions would add 0.7% more to that total.

Some proponents of extending the tax cuts believe that incremental economic activity generated by lowering taxes would largely offset the cuts' cost. While many of their opponents might agree that some positive revenue feedback effect is likely, they believe that its magnitude is considerably smaller than the direct cost of the tax relief. In addition, theory suggests that revenue feedback effects depend on the design of the measures, implying that feedback for some of the provisions of EGTRRA and follow-up legislation would be larger than for others.¹⁹

Partially extending the cuts might represent a compromise that would continue to provide some tax relief, while keeping its costs lower. Some proposals limit tax reductions by directly setting income limits for their recipients. Other proposals try to extend only those tax reductions that benefit taxpayers at the target income range.

Table 3 reproduces CBO estimates of extending the tax reductions by individual provision or a distinct group of provisions.²⁰ The estimates provide the general magnitude of the cost and relative size of extending each provision. However, because of the interaction between the provisions, extending all of the tax provisions would produce a greater revenue loss than the revenue loss indicated by summing up the revenue costs of all the extended provisions.

Finally, there is always an option of providing tax relief through a different set of policies, more loosely or not at all related to the 2001 through 2007 tax cuts. For example, the reductions of some of the marginal rates might be extended, while others let expire, or modified for years after 2010. A large number of possible alternatives are listed in the CBO Budget Options report,²¹ as well as in other publications issued by various government and private entities.

 Table 3. Estimated Revenue Effects of Extending Certain Major

Examination of Table 4 shows that the effective tax rate for all taxpayers fell by 2.8 percentage points, from 11.8% to 9%. However, the gains are distributed unevenly among taxpayers belonging to different quintiles -- groups of one-fifth of all households, arranged by income. Whereas the lowest quintile received a 1.9 percentage point cut, the top quintile's cut was 3.4 percentage points. None of the bottom four quintiles received a cut exceeding 2.5 percentage points, but the taxpayers in the top 1% received a reduction of 4.8 percentage points. Expanding the analysis to include the reductions in the estate tax would likely exacerbate the difference.
