What Is Adjusted Gross Income (AGI)?

Adjusted gross income (AGI) is a US tax measure equal to gross income minus certain specific adjustments, sometimes called above-the-line deductions, such as deductible retirement contributions, HSA contributions, and half of self-employment tax. AGI is the starting point for taxable income and is used to determine eligibility for many deductions and credits.

AGI vs. Taxable Income

Taxable income = AGI − standard deduction (or itemized deductions) − certain other deductions. AGI appears on the federal return, Form 1040.
