Frequently Asked Questions
- Modified Adjusted Gross Income (MAGI) is your Adjusted Gross Income (AGI) with certain deductions added back in. The IRS uses MAGI to determine eligibility for Roth IRA contributions, premium tax credits, student loan deductions, and other tax benefits.
- MAGI = AGI + Specific Add-backs. Common add-backs include: student loan interest deduction, IRA deductions, passive activity losses, excluded foreign income, and half of self-employment tax. This calculator covers the most common scenarios.
- AGI is gross income minus above-the-line deductions (IRA contributions, student loan interest, etc.). MAGI adds some of those deductions back, resulting in a number equal to or higher than AGI. For many people with straightforward finances, MAGI equals AGI.
- MAGI determines eligibility for: Roth IRA contributions (2025: phase-out starts at $150k single / $236k married), traditional IRA deductibility (if you have a workplace plan), premium tax credits for ACA health insurance, Medicare premium surcharges (IRMAA), and Child Tax Credit.
- For 2025: Single filers can contribute the full amount with MAGI under $150,000, with phase-out from $150kโ$165k. Married filing jointly: full contribution under $236,000, phase-out $236kโ$246k. Above the limit, you cannot contribute directly to a Roth IRA (but can use a backdoor Roth).
- For most MAGI calculations, only the taxable portion of Social Security is included (0%, 50%, or 85% depending on your combined income). However, for ACA premium tax credit purposes, the full Social Security benefit is included. This calculator uses the general MAGI definition.
- Yes โ strategies include: maximizing pre-tax 401(k) contributions (reduces AGI/MAGI dollar-for-dollar), contributing to an HSA, harvesting tax losses in investment accounts, deferring self-employment income, and timing Roth conversions carefully.
