Description

For income tax purposes, ADJGINC (Adjusted Gross Income) consists of an individual's total gross (pre-tax) income from taxable sources minus certain items, such as individual retirement plan contributions (payments to a Keogh plan or a deductible Individual Retirement Account), alimony paid, medical savings accounts, and non-reimbursed employee business expenses. ADJGINC minus deductions and personal exemptions equals the individual's taxable income (TAXINC).

ADJGINC, like other tax-related variables included in the ASEC CPS (CAPGAIN, CAPLOSS, EITCRED, FEDRETIR, FEDTAX, FICA, FILESTAT, MARGTAX, STATETAX, TAXINC, and household level variable PROPTAX) was not determined by direct questioning of respondents. Rather, values for these variables come from the Census Bureau's tax model, which simulates individual tax returns to produce estimates of federal, state, and payroll taxes. The model incorporates information from non-CPS sources, such as the Internal Revenue Service's Statistics of Income series, the American Housing Survey, and the State Tax Handbook. For more information about the model, see Current Population Reports, Series P60-18RD. The IPUMS-CPS staff welcomes further information from users about the interpretation of this variable or other tax-related variables in the ASEC CPS.

Amounts for ADJGINC are expressed in dollars of the given year, rather than in constant dollars adjusted for inflation. Users can adjust for inflation using Consumer Price Index adjustment factors.

Comparability

Apart from the effects of inflation, ADJGINC is largely comparable over time. Comparability may, however, be limited by changes in the Census Bureau's tax model. The Bureau implemented a new model to produce tax estimates in 2004, and the previous tax model was updated annually to account for changes in marginal tax rates.
