Before-tax income is the sum of market income and government transfers.
29
30
Market income has the following components:
31
Labor income—Cash wages and salaries, including those allocated by employees to 401(k) plans; employer-paid health insurance premiums; the employer’s share of Social Security, Medicare, and federal unemployment insurance payroll taxes; and the share of corporate income taxes borne by workers.
32
Business income—Net income from businesses and farms operated solely by their owners, partnership income, and income from S corporations.
33
Capital gains—Profits realized from the sale of assets. Increases in the value of assets that have not been realized through sales are not included in the Congressional Budget Office’s measure of market income.
34
Capital income (excluding capital gains)—Taxable and tax-exempt interest, dividends paid by corporations (but not dividends from S corporations, which are considered part of business income), positive rental income, and the share of corporate income taxes borne by owners of capital.
35
Other income—Income received in retirement for past services and other sources of income.
36
37
Government transfers are cash payments from Social Security, unemployment insurance, Supplemental Security Income, Temporary Assistance for Needy Families (and its predecessor, Aid to Families with Dependent Children), veterans’ programs, workers’ compensation, and state and local government assistance programs. They also include the value of in-kind benefits, such as Supplemental Nutrition Assistance Program vouchers (formerly known as food stamps), school lunches and breakfasts, housing assistance, energy assistance, and benefits provided by Medicare, Medicaid, and the Children’s Health Insurance Program. (The value of health insurance is measured on the basis of the Census Bureau’s estimates of the average cost to the government of providing such insurance.)
38
39
After-tax income is the sum of market income and government transfers, minus federal tax liabilities.
40
41
Tax liabilities are the amount of taxes a household owes based on income earned in a year, regardless of when the taxes are paid. In assessments of the impact of various taxes, individual income taxes are allocated directly to households paying those taxes. Social insurance, or payroll, taxes are allocated to households paying those taxes directly or paying them indirectly through their employers. Corporate income taxes are allocated to households according to their share of capital and labor income. Federal excise taxes are allocated to households according to their consumption of the taxed good or service.
42
43
Average tax rates are calculated by dividing tax liabilities by before-tax income. Negative average tax rates result when refundable tax credits, such as the earned income and child tax credits, exceed the tax owed by people in an income group. (Refundable tax credits are not limited to the amount of income tax owed before they are applied.)
44
45
Income categories are defined by ranking all people by their income adjusted for household size—that is, divided by the square root of a household’s size. (A household consists of the people who share a housing unit, regardless of their relationships.) Quintiles, or fifths, contain equal numbers of people, as do percentiles, or hundredths. Households with negative income (business or investment losses larger than other income) are excluded from the lowest income category but are included in totals.
46
47
Income is adjusted for inflation using the personal consumption expenditures price index, which is calculated by the Bureau of Economic Analysis.
