Roth conversion, home or stock sale: why IRMAA won’t drop now
By Elder PaperworkUpdated
Short answer
A one-time jump in income is not a life-changing event for IRMAA.
Social Security names capital gains from a property sale and converting an IRA as examples.
The surcharge usually ends once that tax year is no longer the one Social Security uses.

Key facts
Why can’t I lower IRMAA after a Roth conversion?
Social Security only accepts 8 life-changing events. A one-time gain is not one of them.
It calls these non-qualifying events. Examples it gives:
- Capital gains from selling property
- Converting an IRA
- Cashing in bonds
- Lottery or casino winnings
What other changes don’t count?
- An ordinary loss of dividend income
- Higher medical or living expenses
- Loss of child support or alimony
- A voluntary sale of income-producing property
The list of life-changing events is closed. Other income drops don’t qualify.
When does the higher premium stop?
Each year, Social Security uses a newer tax return. For 2026, that is generally 2024.
So a high year stops counting once it is no longer the year used.
See the lookback year tool.
What if I also retired that year?
Retirement is a work stoppage, which is a life-changing event.
If it lowered your income, you can ask Social Security to use a newer year. Check your case first.
See your possible savings first. No commitment.
