The Sale That Raises Next Year’s Medicare Bill
A married couple, both around 66 and on Medicare, owns a paid-off rental house bought decades ago. The tenants are fine, cash flow is steady, but they are ready to stop being landlords. The problem is the gain. After years of appreciation and depreciation deductions, selling in a single tax year could push their modified adjusted gross income (MAGI) into territory that triggers Medicare surcharges two years later.
This scenario appears frequently in online retirement forums: someone sells a rental, has a strong year on paper, then receives a letter two years later explaining that Part B and Part D premiums just jumped. The surcharge, called the Income-Related Monthly Adjustment Amount, uses a two-year lookback. A 2026 sale shapes 2028 premiums.
National home prices are still rising, up about 0.9% year over year as of April 2026 per the S&P Cotality Case-Shiller index, though growth is forecast to slow further by year-end. For a couple who has owned their rental for decades, that modest recent appreciation barely matters next to the gain built up over the entire holding period, which is exactly why the embedded capital gain on a long-held property can be large even as the broader market cools.
Why One Big Year Costs Two Years of Premiums
The 2026 IRMAA brackets work as cliffs. For a couple filing jointly, Part B stays at the standard premium when MAGI is at or below $218,000. Cross that line by a single dollar and the surcharge kicks in for the entire year, with higher tiers at $274,000, $342,000, $410,000, and $750,000. Part D carries its own parallel surcharge on top.
A rental sale throwing off a six-figure gain can easily vault a retired couple through two or three tiers in one year. Because the surcharge is deducted directly from the Social Security check, the hit lands where it is most visible. It only stops when MAGI drops back below the threshold, meaning the high premium runs for a full calendar year before resetting.
The fix is to control the shape of the income.
Two Ways to Smooth the Gain
- A 1031 like-kind exchange. If the goal is to stay invested in real estate, a 1031 defers the entire gain by rolling proceeds into another investment property. A qualified intermediary must hold the funds, the replacement property must be identified within 45 days, and the purchase must close within 180 days. This only works for investment or rental property, not a future personal residence. The gain is deferred rather than erased; selling the replacement later without another exchange brings the tax bill due.
- An installment sale. If the goal is to cash out, an installment sale lets the buyer pay over several years, and the capital gain is recognized as payments arrive. Spreading the gain across three or five tax years can keep each year’s MAGI under the next IRMAA tier. With the IRS mid-term Applicable Federal Rate near 4.1% as of June 2026, the minimum interest required on seller financing is in a reasonable range for both sides.
The Depreciation Recapture Catch
Depreciation recapture on a rental is taxed as ordinary income at rates up to 25%, and in an installment sale that recapture is generally taxed up front in the year of sale. It does not spread out with the rest of the gain. For a property depreciated for 20 or 30 years, the recapture piece alone can push MAGI over an IRMAA threshold even with payments stretched out.
Model the year-of-sale MAGI with recapture included before signing anything, then size the down payment and payment schedule so the first year lands under the target tier.
How This Lines Up With Social Security
The couple’s Social Security check is the steady piece. The 2026 cost-of-living adjustment (COLA) of 2.8% already flowed through, and the Part B premium comes out of that benefit before it hits the bank. An IRMAA surcharge two years from now would shrink the net deposit for twelve straight months. Smoothing the sale protects the monthly check itself.
If either spouse is still deferring Social Security to grow the benefit, that is another reason to keep the sale year clean. A spike in provisional income now can pull more of the eventual benefit into the taxable column once they start claiming.
What to Sort Out Before Signing
Ask the tax preparer to project MAGI under each scenario, including recapture, so the IRMAA tier is known in advance rather than discovered in a letter. Decide whether the goal is to stay in real estate or be done with it, because that single answer chooses between a 1031 and an installment sale.
The hardest mistake to undo is closing in December and learning in February that the whole gain landed in one tax year. Once the sale is recorded, the IRMAA clock has started. Every situation has its own quirks around state taxes, basis records, and existing income, so the version that works for the neighbors may not work for everyone.
