Medicare has a memory and it's two years long.
Your 2026 Medicare premium is not based on what you earn in 2026. It's based on the tax return you filed for 2024.
That is the whole rule and it changes how you plan.
A Roth conversion you do this year does not touch this year's premium. It sets the premium you pay two years from now.
Sell a rental property this year? Same thing. Two years out.
And it works in the other direction too.
The year you retire, your income usually drops a lot. But your Medicare premium keeps looking at the old, higher return. So you can be living on a much smaller income and still be paying a high income premium.
For two more years.
Here's the part almost nobody uses.
Retiring counts as a life-changing event. There is a form for it. It is called SSA-44. You give Social Security proof that your work stopped, and you ask them to use your current income instead of that old return.
It is not automatic. You have to ask.
So if you retired recently and your Medicare premium looks too high, that is not a mistake you have to accept. That is a form you have not filled out yet.
Save this and share it with someone who just retired.
