2026 IRMAA brackets for Part B and Part D

IRMAA stands for Income-Related Monthly Adjustment Amount. It is an extra charge on top of your Medicare premiums. Social Security sets it from the income on your tax return from two years earlier.

How to lower your IRMAA

IRMAA looks back two years. If your income has dropped since 2024 because your life changed, you can ask Social Security to use a more recent year instead. You do this with Form SSA-44. Social Security accepts 8 life-changing events:

These are not life-changing events

A one-time Roth conversion, selling your home, or a big capital gain raised your income, but none of them is on the list. Social Security turns down SSA-44 requests based on them. Your IRMAA drops on its own two years later, when that income is no longer on the tax return they use.

Questions people ask

Which year's income is used for 2026 IRMAA?

Your 2024 tax return, filed in 2025. If the IRS only has your 2023 return, Social Security uses that and corrects it later.

What counts as income (MAGI) for IRMAA?

Your adjusted gross income (Form 1040, line 11) plus tax-exempt interest (line 2a). Roth IRA withdrawals do not count. Roth conversions, capital gains and required minimum distributions do.

Do both spouses pay IRMAA?

Yes, if both are on Medicare. Each person pays the surcharge on their own premium, so a married couple in the same bracket pays it twice.

Can I lower my IRMAA?

Yes, if your income dropped because of one of 8 life-changing events, such as retiring, cutting back work, divorce, or the death of a spouse. You ask with Form SSA-44. A one-time Roth conversion or home sale is not a life-changing event.

When will the 2027 IRMAA brackets come out?

CMS usually announces the next year's Part B premium and brackets in mid-November. The 2027 brackets will be based on your 2025 income.
