Adjusted Gross Income

Adjusted gross income, or AGI, is the amount of a taxpayer's income from which exemptions and deductions are subtracted to determine the taxpayer's taxable income.

Adjusted gross income is calculated by subtracting from gross income the following amounts: unreimbursed business expenses, contributions to health savings accounts, moving expenses, half of self-employment tax, contributions to retirement accounts, alimony paid, college tuition and fee payments, and jury duty pay given to the taxpayer's employer.

Adjusted gross income is used as the basis for phasing out certain tax deductions, including contributions to Individual Retirement Accounts and the Earned Income Tax Credit.
