Medicare Sets 2026 IRMAA Premiums From 2024 MAGI, Lifting Part B to $689.90

Summary
2026 Medicare premiums for higher-income beneficiaries will be based on 2024 modified adjusted gross income, with the standard Part B premium at $202.90 a month.
Single filers above $109,000 and couples above $218,000 face IRMAA surcharges on both Part B and Part D, with the top tier starting at $500,000 single or $750,000 joint.
At that highest bracket, Part B rises to $689.90 a month and Part D adds $91 on top of the drug plan premium; crossing a threshold by even $1 can trigger the next tier.
Beneficiaries whose income has fallen after retirement or another qualifying life event can ask Social Security for a new determination using Form SSA-44, though Roth conversions, capital gains and business sales often still count.
The two-year lookback means one-time income spikes in 2024 can raise 2026 Medicare costs, making tax and withdrawal planning a key tool for affluent retirees.
