CRFB on Tax Expenditures

October 15, 2010

The above chart is taken from a short report by the Committee for a Responsible Federal Budget (CRFB) regarding federal income tax expenditures. Income tax expenditures are special tax benefits for targeted groups and are unnecessary for the basic revenue-raising function of the income tax. They result either in reduced revenues or increased taxes elsewhere, or some combination of the two. Tax expenditures are really just government spending cleverly hidden in the tax code. According to the report, tax expenditures “result in more than $1 trillion in forgone revenue a year – more than 6 percent of GDP. These revenue losses were larger than all income taxes paid by individuals last year.”

One of the problems-indeed, the great political appeal-of tax expenditures is that they are not subject to annual budget review: they are created without the same level of scrutiny received by other areas of the budget, and then run open-ended with little review. Because they escape the normal budget process, policymakers have found them particularly attractive, and the tax expenditure budget has grown tremendously.

The tax code contains around 250 tax expenditures, double the number from only a few years ago. Adoption of these deductions, credits, exemptions, exclusions, and other tax preferences has undercut the effectiveness, efficiency, transparency, and fundamental fairness of the tax system. The result is a Swiss-cheese tax base filled with rifle-shot tax breaks which, much like entitlement programs, are on automatic pilot and do not receive sufficient scrutiny as part of the budget process.

While CRFB recommends some ambitious reforms, such as eliminating the deduction for state and local taxes paid, others are fairly modest, such as their proposal to limit deductible mortgage interest to the interest paid on mortgages with a value of $500,000 or less (the current limit it $1 million) and disallowing the deduction for second homes. Most policy experts believe that we need fundamental tax reform, and that can only be accomplished if tax expenditures are vastly curbed. The only question is one of political will.
