Higher 2024 income boosts 2026 Medicare costs
Medicare’s two-year lookback means 2024 income events can spike 2026 Part B and Part D bills.
A 67-year-old couple found $500 less in their January 2026 Social Security deposit due to a 2024 Roth conversion.
The conversion pushed their modified adjusted gross income into a Medicare income-related surcharge bracket, resulting in up to $480 more monthly for the entire year.
