How are federal taxes distributed?
Although enterprises (e.g., retailers, employers) are legally obligated to pay certain taxes, the burden of all taxes ultimately falls on households.
Individuals, businesses, and other entities may have the legal obligation to pay certain taxes, but the economic burden (or incidence) of all taxes ultimately falls on households. This burden may be felt through a reduction in household income or higher prices for goods and services.
The incidence of taxes has been studied for decades, and there is now fairly broad agreement on how it is distributed across households. The Tax Policy Center, in preparing standard distribution tables, assumes the following about federal taxes:
Individual income tax
Taxpayers (who either pay the tax directly or receive a refundable credit) bear the entire burden of the individual income tax.
Employees (or self-employed people who pay both shares of the tax) bear both the employer and the employee share of the Social Security and Medicare payroll tax in the form of lower take-home income.
Corporate income tax
The corporate income tax reduces both wages and returns to capital. Income from capital (e.g., dividends, rents, interest, and capital gains) bears four-fifths of the burden, with wages and other sources of labor income bearing the remaining fifth.
These costs are borne entirely by decedents.
These also are assumed to reduce wages and returns to capital. They also increase the relative price of taxed goods and services, so households that consume relatively more of the taxed items bear a higher burden.
The Joint Committee on Taxation (JCT), US Department of Treasury’s Office of Tax Analysis, and the Congressional Budget Office make similar incidence assumptions in their analyses, but with a few differences. For instance, JCT assumes that the tax on individual income that represents a return to capital from noncorporate businesses, like partnerships, is borne in the same manner as the corporate income tax. Moreover, each of these groups follows slightly different incidence assumptions for the corporate income tax, reflecting the great degree of uncertainty over the incidence of this tax.
