Medicare Part D income limits involve two different situations: lower limits for the Extra Help program (LIS) to reduce costs for those with low income and resources, and higher limits that trigger Income-Related Monthly Adjustment Amounts (IRMAA), meaning higher premiums for high-income earners, based on your prior year's tax return (e.g., 2024 income for 2026 costs).

For IRMAA, higher premiums start for individuals earning over $109,000 (or $218,000 joint) in 2024, with escalating surcharges for higher incomes.
