What is IRMAA?

IRMAA — the Income-Related Monthly Adjustment Amount— is an extra amount higher-income retirees pay on top of their standard Medicare Part B and Part D premiums. It isn’t a tax you file; it’s a surcharge Social Security applies automatically based on your income from two years ago.

What you’ll actually pay in 2026

Based on your 2024 modified adjusted gross income (MAGI). The standard Part B premium is $202.90; everything above it is IRMAA.

TIERMARRIED (JOINT)PART B / MO
StandardUp to $218,000$202.90
1$218,001 – $274,000$284.06
2$274,001 – $342,000$405.80

4$410,001 – $750,000$649.28
5$750,000 & above$690.06

Part B amounts are the total monthly premium (standard + IRMAA). Part D IRMAA is added on top of your drug plan’s premium. Married-filing-separately thresholds differ. Figures are 2026 amounts (Social Security / CMS) and are subject to annual adjustment — verify before publishing.

HOW IT’S DECIDED

Two rules that catch people off guard.

The two-year lookback

Your 2026 premiums are set by your 2024 tax return. A one-time income event — a home sale, a large Roth conversion, an inherited IRA — can raise your premiums two years later, long after the money is spent.

It's a cliff, not a ramp

Cross a threshold by a single dollar and you jump to the next tier's full surcharge — for the entire year. That's why the last few thousand dollars of income before a bracket edge matter so much.

Ways I help clients plan around it
Timing Roth conversions to fill — but not overflow — a bracket
Spreading capital gains and large withdrawals across tax years
Using Qualified Charitable Distributions to lower MAGI
Appealing IRMAA after a life-changing event (Form SSA-44)
Coordinating with Social Security so the net check stays healthy
