A couple in their mid-60s sold a rental house two years ago, paid the capital gains and depreciation recapture taxes they expected, and assumed the chapter was closed. Then their Medicare premium notice arrived. Their Part B and Part D bills had jumped, and the combined surcharge for the year would run roughly $5,600. They had walked into IRMAA, the income-related monthly adjustment amount, tied directly to that rental sale.
If that sounds familiar, you are not alone. Medicare uses a two-year lookback on modified adjusted gross income, so a one-time spike from a property sale, Roth conversion, or business exit in 2024 shows up in your 2026 premium. IRMAA works as a cliff. Cross a threshold by one dollar and the entire surcharge kicks in.
The Scenario
Consider a married-filing-jointly couple, ages 65 and 66, with about $2.3 million across brokerage, IRA, and home equity. They sold a long-held rental property two years ago and booked a roughly $210,000 taxable gain. Part of that gain was depreciation recapture, taxed at ordinary rates up to 25%, with the remainder treated as long-term capital gain. Add that gain to their roughly $130,000 of pensions, Social Security, and investment income, and their MAGI landed near $340,000 for the year.
That figure now drives their 2026 Medicare premiums, landing them squarely in the joint-filer band greater than $274,000 and less than or equal to $342,000.
At that income band, each spouse pays a Part B IRMAA of $202.90 per month on top of the standard premium, bringing the total Part B premium to $405.80 per month per person. Layer on the Part D surcharge of $37.50 per month per person and the couple’s combined IRMAA-driven cost for the year clears roughly $5,600. Drop one bracket lower and the Part B surcharge would have been only $81.20 per month each.
Once the gain rolls out of the lookback window, premiums reset to the standard amount of $202.90 per month per person, assuming income normalizes. Once the gain is realized, the IRMAA bill is unavoidable.
Strategic Paths
For a couple who has already sold, options are narrow. For one still holding the property, the menu is wider.
- Installment sale. Spreading the gain across three to five tax years can keep MAGI in a lower IRMAA band each year. A $210,000 gain recognized in one year pushed this couple past $274,000. Spread across three years, the same gain may keep them under the $218,000 threshold entirely. Depreciation recapture is still recognized in year one, so model carefully.
- 1031 exchange. A like-kind exchange defers both the capital gain and the recapture if a replacement property is identified within the IRS deadlines. The money is held by an intermediary, but then you are on an expedited schedule to identify another property and get that closed. This only works if you want to stay in the rental business.
- Bunch the sale into a pre-Medicare year. Selling at 63 instead of 65 sidesteps IRMAA entirely on that gain, since the lookback never reaches a Medicare year. For couples approaching 65 with a sale on the horizon, this decision can be worth thousands.
- SSA-44 appeal, but only with a qualifying event. Qualifying events include work stoppage, marriage, divorce, or death of a spouse. A property sale on its own falls outside the list.
Before signing any sale contract on appreciated real estate after age 63, run a MAGI projection for the year of sale and check it against the joint IRMAA bands: $218,000, $274,000, $342,000, $410,000, and $750,000. Knowing which threshold you are about to cross tells you whether an installment structure is worth the friction.
The common mistake is treating the capital gains tax as the whole cost. The invisible costs often exceed it. With the 2026 Social Security COLA at 2.8% and the standard Part B premium already at $202.90, a one-bracket IRMAA jump can erase an entire year of cost-of-living raises for both spouses. Plan the sale around the MAGI thresholds alongside the gain itself.
