If your 2024 modified adjusted gross income (MAGI) exceeds $109,000 (individual) or $218,000 (married filing jointly) in 2026, you will pay a higher monthly premium, known as the Income-Related Monthly Adjustment Amount (IRMAA), in addition to your plan's premium.

Yes, Medicare Part D premiums are based on income for higher earners, who pay an extra amount called the Income Related Monthly Adjustment Amount (IRMAA) in addition to their plan's standard premium, determined by their modified adjusted gross income (MAGI) from two years prior, with lower-income individuals potentially qualifying for Extra Help.
