Joint Tax Committee Releases Tax Expenditure Estimates for 2012-17

The Joint Committee on Taxation has released Estimate of Federal Tax Expenditures for Fiscal Years 2012-2017 (JCS-1-13):

Tax expenditure analysis can help both policymakers and the public to understand the actual size of government, the uses to which government resources are put, and the tax and economic policy consequences that follow from the implicit or explicit choices made in fashioning legislation. This report on tax expenditures for fiscal years 2012-2017 is prepared by the staff of the Joint Committee on Taxation. ... As in the case of earlier reports, the estimates of tax expenditures in this report were prepared in consultation with the staff of the Office of Tax Analysis in the Department of the Treasury.

The Joint Committee staff has made its estimates (as shown in Table 1) based on the provisions in Federal tax law as enacted through January 2, 2013. Expired or repealed provisions are not listed unless they have continuing revenue effects that are associated with ongoing taxpayer activity. Proposed extensions or modifications of expiring provisions are not included until they have been enacted into law. The tax expenditure calculations in this report are based on the January 2012 Congressional Budget Office revenue baseline and Joint Committee staff projections of the gross income, deductions, and expenditures of individuals and corporations for calendar years 2011-2017.

Part I of this report contains a discussion of the concept of tax expenditures. Part II is a discussion of the measurement of tax expenditures. Estimates of tax expenditures for fiscal years 2012-2017 are presented in Table 1 in Part III. Table 2 shows the distribution of tax returns by income class, and Table 3 presents distributions of selected individual tax expenditures by income class.
