Modified Adjusted Gross Income (MAGI)
MAGI is your AGI with certain deductions added back — it determines your eligibility for Roth IRA contributions, IRA deduction limits, and several education credits.
For Roth IRA purposes, MAGI is your AGI plus student loan interest deduction, foreign earned income exclusion, and several less common items. In 2026, MAGI under $153,000 (single) or $240,000 (married filing jointly) lets you make a full Roth IRA contribution. Between $153k-$168k single or $240k-$250k joint, your allowed contribution phases down. Above the top of the phase-out range, direct Roth contributions are not allowed — but a 'backdoor Roth' via a nondeductible traditional IRA contribution and same-day conversion usually still works, pro-rata rule permitting.
