AGI Explained: What Counts Toward Adjusted Gross Income and How to Find Yours

Adjusted Gross Income (AGI) is your total income minus specific "above-the-line" adjustments. It appears on Form 1040 Line 11 and affects tax credits, IRA contributions, and more. Here's what counts and how to find yours.

What Is AGI?

AGI = Total income from all sources minus above-the-line deductions. It comes *before* the standard deduction or itemized deductions. Taxable income = AGI minus standard/itemized deduction minus qualified business income deduction.

What Income Counts Toward AGI?

  • Wages, salaries, tips
  • Interest, dividends, capital gains
  • Self-employment income
  • Rental income
  • Retirement distributions (IRA, 401k, pension)
  • Unemployment, Social Security (taxable portion)
  • Alimony received, etc.

Exclusions (not in AGI): municipal bond interest, certain foreign earned income, gifts, life insurance proceeds.

Common Above-the-Line Deductions

  • Traditional IRA contributions
  • Student loan interest (max $2,500; phase-out applies)
  • Educator expenses (max $300 per educator)
  • Self-employed health insurance
  • 50% of self-employment tax
  • SEP, SIMPLE contributions
  • Alimony paid (pre-2019 divorces)

Why Your AGI Matters

AGI determines eligibility for the Earned Income Tax Credit, Child Tax Credit, Roth IRA contributions, student loan interest deduction, premium tax credits, and free e-file. A lower AGI can unlock more benefits.

Where to Find Last Year's AGI

  • Form 1040 Line 11 (or Line 8b on older forms)
  • Your copy of your filed return
  • IRS transcript (create an account at IRS.gov)
