A husband already on Medicare. A wife who isn’t yet.
Most people hear that and think: fear IRMAA!
But what if its a strategic planning window?
Medicare generally looks back two years at income. So the years before both spouses are enrolled can be some of the most flexible planning years a couple gets. Once they’re both on, crossing that threshold costs more.
That doesn’t mean convert. It means the question isn’t really whether. It’s how much, and by when.
And there’s a piece almost nobody brings up: if one spouse outlives the other, the standard deduction goes from a couple’s to a single person’s. The RMDs don’t shrink to match.
If you’re within a few years of Medicare and you’ve wondered about Roth conversions, send this to the person you’d be making that decision with.
