See what you pay for Medicare Part B and Part D in 2026, and whether your income adds a surcharge (IRMAA).

Common questions

What is IRMAA?

An extra charge on Medicare Part B and Part D premiums for people with higher income. Social Security looks at your tax return from two years ago, so 2026 premiums use 2024 income.

What if my income dropped since then?

If it dropped because of retirement, marriage, divorce, a spouse's death or another life-changing event, ask Social Security to use your newer income with Form SSA-44.

Why does $1 over the line matter?

IRMAA tiers are cliffs. Going $1 over a limit adds the whole surcharge for the year. If you are close, timing a Roth conversion or a large withdrawal can matter.

How is Part B paid?

If you get Social Security, Part B comes out of your check before it is deposited. Otherwise Medicare sends a bill.

Can I get help paying Medicare premiums?

Yes. If your income and savings are low, a Medicare Savings Program can pay your Part B premium. Oregon and Washington run these through OHP and Apple Health. See the benefits calculator.

When will 2027 premiums be announced?

Medicare usually announces next year's Part B premium in November. We'll update this page when it does. 2027 premiums will use 2025 income.
