Step 1 of 5
Step 1 of 5

Which premium year are you planning for?

IRMAA uses income from 2 years prior. For 2026 premiums, SSA looks at your 2024 tax return.

Step 2 of 5

What's your tax filing status?

IRMAA thresholds differ by how you filed in the lookback year.

Step 3 of 5

Who is on Medicare?

IRMAA applies per person. If both spouses are enrolled, the surcharge applies to each one separately.

Step 4 of 5

What's your estimated income (MAGI)?

MAGI = AGI + tax-exempt interest. From your lookback year tax return.

Frequently Asked Questions About IRMAA

Get clear, accurate answers about how Medicare IRMAA works — and how to plan around it.

SSA uses a two-year lookback. Your 2026 Medicare premiums are based on the income reported on your 2024 federal tax return. If your 2024 return hasn't been processed yet, SSA may use 2023 data as a bridge. Learn more: IRMAA two-year lookback explained.
Medicare MAGI = your Adjusted Gross Income (Form 1040, line 11) plus any tax-exempt municipal bond interest (line 2a). This includes wages, self-employment income, Social Security (taxable portion), pension payments, RMDs, capital gains, Roth conversions, rental income, and IRA/401(k) withdrawals. Roth distributions are generally excluded. See: What counts toward IRMAA MAGI.
Yes. IRMAA is assessed per person. If both spouses are enrolled in Medicare Part B and Part D, each one pays the surcharge based on their household MAGI. A couple with joint MAGI of $300,000 in Tier 2 would pay the Tier 2 surcharge twice — once per person — doubling the household cost.
Yes — a Roth conversion adds taxable income to your MAGI in the year it occurs, which can push you into a higher IRMAA tier two years later. Careful timing and sizing of conversions is key. Use our Roth conversion IRMAA calculator to model the exact impact.
IRMAA is reassessed every year based on your most recent available tax return. If your income dropped, your IRMAA tier drops too — but with the two-year lag, there's no instant relief. If income spikes one year (e.g., a large home sale), you typically pay higher premiums for just one year, then return to your normal tier.
Yes. If you had a qualifying life-changing event — such as retirement, divorce, death of a spouse, or loss of pension income — you can file SSA Form 44 to request that SSA use your more recent (lower) income instead of the lookback year. Check timing and eligibility with our SSA-44 appeal timing checker.
Yes — both realized capital gains and taxable proceeds from a home sale (above the $250k/$500k primary-residence exclusion) count toward MAGI. A large one-time gain can temporarily push you into a higher IRMAA bracket two years later. See: capital gains IRMAA calculator and home sale calculator.
CMS typically announces the following year's Medicare premiums and IRMAA brackets in November or early December. The 2027 brackets will most likely be published in November 2026. Brackets are adjusted annually for inflation using a formula tied to the Consumer Price Index for medical costs. We update this tool as soon as official figures are released.
