2026 Medicare Bills Linked to 2024 Income Changes for Retirees

The 2026 Medicare Part B and Part D bills can be significantly affected by income changes in 2024, such as Roth conversions or property sales. Those exceeding the income threshold face surcharges up to $480 monthly for the entire year. Approximately 8% of Medicare Part B recipients may experience these adjustments due to the two-year lookback rule implemented by CMS. It is essential for retirees to be aware of their modified adjusted gross income, as it determines their IRMAA surcharge based on tax filings from 2024.
