Among the options likely to be considered to deal with the long-term fiscal problem is reform of the federal tax system. The growth of the alternative minimum tax (AMT) and the expiration of the 2001 and 2003 tax cuts in 2010 will likely force some action on tax policy. The perception that the federal tax system is too complex and unfair could lead to public support for tax reform. Past efforts to reform the federal tax system have included policies to rein in the use and expense of tax expenditures--the special deductions, exclusions, exemptions, and credits resulting in revenue losses. This report examines tax expenditures within the context of the federal budget and discusses tax expenditure analysis.
