2026 Medicare Premium Changes

What’s the real price of Medicare in 2026? Not the standard premium everyone quotes. For affluent retirees, the bill is set by your income from two years back, and it can more than triple. The 2026 numbers are out, so let’s separate the sticker price from what you’ll actually pay.

Medicare isn’t free. Part B, the piece that covers doctors and outpatient care, charges a monthly premium, and for high earners that premium comes with a surcharge most people never see coming.

The 2026 baseline

The standard Part B premium for 2026 is $202.90 a month, up from the prior year. The annual Part B deductible is $283. If your income sits below the surcharge thresholds, that’s your number, and most retirees pay exactly that.

That premium usually comes straight out of your Social Security check, which is why a Medicare increase can quietly shrink the COLA raise you thought you were getting.

The number that actually decides your bill

Here’s where the sticker price stops mattering. If your income clears certain lines, you pay IRMAA, the Income-Related Monthly Adjustment Amount, on top of the standard premium.

For 2026 the surcharge tiers push your total Part B premium up in steps. A single filer over $109,000 (or a couple over $218,000) leaves the standard rate behind. At the top, single filers at $500,000 or more and couples at $750,000 or more pay $689.90 a month for Part B. That’s more than three times the standard premium. Part D, the drug coverage, tacks on its own surcharge running up to $91.00 a month at the top tier.

And it’s per person. A married couple both on Medicare pay these premiums and surcharges twice.

The trap inside the bill

Now the part that catches people. Your 2026 premium runs on your 2024 tax return. Medicare looks back two years, so the income that sets this year’s bill is income you already reported and can’t take back.

That delay is what makes IRMAA so easy to trip. A 2024 Roth conversion, a home sale, a big capital gain, a year you sold a business, all of it surfaces on your Medicare premium in 2026, long after you’ve forgotten the cause. People see the higher bill and have no idea what triggered it.

What to do about it

The planning lives two years upstream. Before you take a chunk of income, find the nearest IRMAA line and know what crossing it costs, because the surcharge is a cliff. One dollar over buys the full higher tier for all twelve months. Sizing a Roth conversion to stop just under a bracket is one of the highest-value moves in retirement tax planning.

If a one-time event spiked your income, like retiring, selling a business, or losing a spouse, file Form SSA-44 with Social Security to claim a life-changing event. The surcharge can come off. Most people never file it because they don’t know it’s there.

The standard premium is the number Medicare advertises. Your income from two years ago is the number that bills you. Run the two-year lookback before the income hits, not after the premium does.
