Will Selling My House Trigger IRMAA?
A home sale can generate a large one-time gain. Find out if selling your house will trigger an IRMAA surcharge two years later — and by exactly how much.
Primary residence exclusion: If you've lived in your home for at least 2 of the last 5 years, the first $250,000 of gain (single) or $500,000 (married jointly) is excluded from taxable income — and from IRMAA. Only the gain above that exclusion affects your Medicare premiums.
How this works: Medicare uses your income from 2 years ago to set your 2026 premiums. A capital gain or home sale in 2024 adds to your 2024 MAGI, which determines your 2026 IRMAA surcharge. This calculator models that impact.
Home Sale & IRMAA — Frequently Asked Questions
- It depends on the size of your gain and whether you qualify for the primary residence exclusion. If you've lived in your home for 2 of the past 5 years, up to $250,000 of gain is excluded from income (single filers) or $500,000 (married filing jointly). Only the taxable gain after that exclusion counts toward IRMAA. If your taxable gain pushes your MAGI above an IRMAA threshold, your Medicare premiums will be higher two years after the sale.
- Single filers who meet the 2-of-5-year ownership and use test can exclude up to $250,000 of gain from a primary residence sale. Married couples filing jointly can exclude up to $500,000. The amount above the exclusion is taxable — and that taxable gain is included in your MAGI for IRMAA purposes.
- Medicare uses a 2-year lookback rule. A home sale in 2024 appears on your 2024 tax return, which Medicare uses to set your 2026 premiums. If the gain triggers IRMAA, you would pay the surcharge starting January 2026. You can appeal the surcharge using SSA Form SSA-44 if you had a qualifying life-changing event that reduced your income after the sale.
- The primary residence exclusion only applies to your main home (the one where you lived 2 of the past 5 years). Rental properties, vacation homes, and investment real estate do not qualify for the exclusion. The entire gain from those sales counts toward your MAGI and can push you into a higher IRMAA bracket.
- Several strategies may help: (1) Offset gains with capital loss harvesting from your investment portfolio. (2) Maximize deductible expenses — selling costs, improvements, and depreciation recapture adjustments. (3) If you had a life-changing event such as retirement in the same year, consider filing SSA Form SSA-44 to have Medicare use a lower projected income. Consult a tax professional for your specific situation.
