IRMAA Surcharge Impacts Retirees Two Years After Property Sale
Retirees who sold property in 2024 and realized large capital gains are now facing increased Medicare premiums due to the Income-Related Monthly Adjustment Amount (IRMAA). The surcharge is based on a two-year lookback rule, which uses modified adjusted gross income from prior tax returns. This has led some married couples with combined incomes exceeding $340,000—including capital gains and other retirement income—to face annual premium increases of over $5,600.
