Adjusted gross income (AGI)

Also called MAGI (modified AGI, a related figure)

Total income minus certain specific adjustments, such as deductible IRA and HSA contributions; it is the starting point for many tax calculations.

What it means

Adjusted gross income starts with gross income, including wages, interest, dividends, business income and capital gains, then subtracts a set list of adjustments, sometimes called above-the-line deductions. Examples include deductible traditional IRA contributions, HSA contributions made outside payroll, student loan interest and half of self-employment tax.

AGI matters well beyond the tax return line itself. Eligibility for many credits and deductions, the ability to contribute to a Roth IRA, and some health insurance subsidies are based on AGI or a modified version of it. Taxable income is then found by subtracting the standard or itemized deductions from AGI.

Formula

AGI = Gross income − Adjustments to income

  • Gross income = all taxable income from every source
  • Adjustments = specific deductions allowed before the standard or itemized deduction

Example

Suppose someone has $60,000 of gross income, contributes $5,000 to a deductible traditional IRA and $2,000 directly to an HSA. Their AGI is $60,000 − $5,000 − $2,000 = $53,000.

  • Checking eligibility for credits and Roth IRA contributions
