If you have Medicare Part B and/or Medicare Part D prescription drug coverage, you could owe a monthly surcharge based on an income-related monthly adjustment amount (IRMAA). This surcharge is paid by Medicare beneficiaries for Parts B and D Medicare, in addition to the standard premiums, if their taxable income exceeds certain thresholds. For 2026, the IRMAA income brackets and surcharges increased by approximately 3% and 9%, respectively.
The Medicare surcharge in 2026 applies to beneficiaries with income exceeding $109,000 (for single filers and married filing separately) or $218,000 (for joint filers). For these beneficiaries, total monthly Part B premiums range from $284.10 to $689.90. Part D surcharges range from $14.50 to $91.00.
