So-called “tax expenditures” are special provisions in the tax code that reduce the taxes of a specific group of taxpayers who meet certain criteria. These special exemptions will cost the federal government trillions of dollars over the next few years. In fact, the total budgetary impact of tax expenditures is roughly equal to the amount Congress appropriates in discretionary spending each year, roughly $1 trillion.

Tax expenditures are similar to direct spending because they are used by Congress as a means of accomplishing budget policy objectives. They differ from direct spending in important ways. Unlike discretionary spending, which is debated and approved by Congress each fiscal year, tax expenditures exist for multiple years or even indefinitely, unless or until Congress removes or alters them. In this way, tax expenditures are similar to entitlement programs like Social Security because their costs are based on formulas that rarely change. Also, because tax expenditures depend on the level of taxes owed by the targeted taxpayers, the total cost to the federal treasury can be difficult to estimate from year to year.

Tax expenditures are one area Congress is considering reforming as part of an overhaul of the federal tax code. A brief description of some of the tax expenditures TCS has recommended repealing as part of a solution to our long-term fiscal challenges can be found in our report, "Sliding Past Sequestration: $2 Trillion in Common Sense Cuts to Avoid the Fiscal Cliff." Also see "Green Scissors 2012" for a discussion of cutting tax expenditures in different sectors, especially the energy sector. A more extensive description of tax expenditures is also available from the Senate Budget Committee

The tax expenditure estimates for fiscal years 2012-2017 presented in this data set were prepared by the staff of the Joint Committee on Taxation for the House Committee on Ways and Means and the Senate Committee on Finance, in consultation with the staff of the Office of Tax Analysis in the Department of the Treasury. Tax expenditures presented here are only those that are part of the income tax – they do not include exceptions, exclusions, or credits from other Federal taxes such as excise taxes, employment taxes, or estate and gift taxes.

The General Accounting Office (GAO) has criticized tax expenditures because they:

  • can contribute to mission fragmentation and program overlap, creating the potential for duplication;
     
  • may be ineffective at achieving their social or economic purposes;
     
  • are effectively funded before discretionary spending is considered;
     
  • may or may not be subject to congressional reauthorization.

GAO further states that: “reductions in revenue losses from eliminating ineffective or redundant tax expenditures could be substantial ... GAO believes that tax expenditure performance is an area that would benefit from enhanced congressional scrutiny as Congress considers ways to address the nation’s long-term fiscal imbalance.”
