How a High Income Year Can Trigger IRMAA
Why a good income year can cost more later
It’s funny how a “good year” can come back to bite you.
You sell a property, take a big distribution, or do a Roth conversion, and everything feels fine—until two years later when your Medicare premiums jump.
The income events that affect IRMAA
That’s IRMAA — the Income-Related Monthly Adjustment Amount. It’s how Medicare quietly raises your costs if your income crosses certain thresholds.
Here’s the kicker: IRMAA uses your income from two years ago. Something you did in 2023 can raise your 2025 premiums.
How Medicare surcharge tiers work
Most people never see it coming. They just open a letter from Social Security and assume there’s a mistake.
There isn’t. You just made too much—for one year.
Roth conversions and capital gains require coordination
This doesn’t mean you should avoid good years or skip smart tax moves. It means you plan them intentionally.
If you’re converting to a Roth, selling stock, or realizing capital gains, keep an eye on those IRMAA brackets.
Why timing matters across tax years
Spacing things out over a couple of years can save thousands in unnecessary premiums.
A “good year” doesn’t have to be a costly one—if you know what’s coming.
