A 68-year-old widower sold the four-bedroom colonial he had owned since 1994, moved into a low-maintenance condo, and pocketed a check large enough to feel like freedom. Two years later, his Medicare Part B premium arrived at exactly twice the standard amount. Nothing about his lifestyle changed. His 2024 tax return did.

The 2026 IRMAA surcharge begins when 2024 modified adjusted gross income exceeds $109,000 for single filers or $218,000 for joint filers. Roughly 8% of Part B beneficiaries pay IRMAA at all. For retirees who triggered a one-time income spike two years ago, the tax return may be old news, but the Medicare bill lands now.

The two-year lookback locks in 2024 income

Social Security generally sets each year’s IRMAA using the tax return from two years back. The 2024 return drives 2026 premiums. The 2025 return drives 2027. The 2026 return drives 2028. A later drop in income does not erase a voluntary home-sale gain unless a qualifying life-changing event also applies.

MAGI for IRMAA is adjusted gross income, Form 1040 line 11, plus tax-exempt interest from line 2a. The municipal bond coupons that feel tax-free still count. So does taxable capital gain from the home sale after the primary-residence exclusion, which can shield up to $250,000 of gain for a single filer or $500,000 for a married couple filing jointly.

Here is where the widower got hit. He bought the house for $180,000, sold it for $520,000 after selling costs and improvements, and realized a gain of roughly $338,000. As a single filer, he shielded $250,000 and reported the remaining $88,000 as long-term capital gain. Add about $52,000 of taxable Social Security, pension income, and interest, and his 2024 MAGI cleared $140,000.

What the second IRMAA tier costs in 2026

CMS published the 2026 brackets on November 14, 2025. The standard Part B premium is $202.90 per month, up from $185.00 in 2025. His MAGI of $140,000 lands him in the second IRMAA tier for single filers, greater than $137,000 and up to $171,000, where the surcharge is $202.90 per month and the total Part B premium becomes $405.80. Precisely double.

Part D piles on. At $140,000 of MAGI, the Part D IRMAA is $37.50 per month, on top of whatever the drug plan itself charges. His combined Part B and Part D IRMAA is $240.40 per month, or $2,884.80 for the year. IRMAA is redetermined annually, so if his 2025 income drops below the next applicable threshold, his 2027 premium can fall with the next tax return.

SSA-44 will not save him

The form readers reach for first is the wrong one here. SSA-44 lets Social Security recalculate IRMAA after a qualifying life-changing event: marriage, divorce or annulment, death of a spouse, work stoppage, work reduction, certain losses of income-producing property, loss of pension income, or an employer settlement payment. A voluntary home sale is not on the list. A primary residence generating a one-time capital gain does not qualify by itself.

Three actions that actually change the bill

• Model the bracket before you sign the listing agreement. A single filer with $95,000 in other MAGI can use the home-sale exclusion without increasing IRMAA if all of the gain is excluded. Add $50,000 of taxable gain and the 2026 Part B premium moves to $405.80, because MAGI reaches $145,000. Add $80,000 and the same second-tier surcharge applies. The threshold drives the outcome, not the sale price by itself.

• Consider timing before the closing date is fixed. An installment sale may spread taxable gain across years, and basis adjustments or selling expenses can reduce the taxable amount if they are legitimate and properly documented. A delayed closing can also shift the income year. These moves need tax advice before the contract is signed, because the Medicare result follows the tax return.

• If a qualifying event actually happened, file SSA-44 with documentation. A retirement letter, death certificate, or divorce decree may support the form if the event reduced income. Voluntary Roth conversions and home sales do not qualify by themselves, no matter how much they raised MAGI.

The Sale Price Is Not the Medicare Number

A home sale can be the right financial move and still create a one-year Medicare surprise. The number that matters is not the check at closing. It is the taxable gain that survives the primary-residence exclusion, plus the rest of the retiree’s MAGI. Once that number crosses an IRMAA line, the premium change arrives two years later, long after the moving boxes are gone.

Figures reflect the 2026 plan year. Medicare Part B premium, IRMAA threshold, and Part D IRMAA figures come from CMS’s 2026 Medicare Parts A & B Premiums and Deductibles fact sheet. Home-sale exclusion rules come from IRS Topic No. 701 and IRS Publication 523. SSA-44 qualifying life-changing events come from Social Security Administration Form SSA-44.
