Columbus Acquisition Corp Ordinary SharesColumbus Acquisition Corp Ordinary SharesMedicare’s Part D Income-Related Monthly Adjustment Amount, or IRMAA, can add up to $91 per person per month on top of any drug plan premium, including plans with a $0 premium. The surcharge applies to roughly 8% of Part D beneficiaries and is based on modified adjusted gross income from two years prior, with 2026 surcharges keyed to 2024 tax returns. For 2026, single filers with 2024 MAGI above $109,000 and joint filers above $218,000 face monthly surcharges ranging from $14.50 to $91.00 per person. A married couple at the highest tier pays $182 monthly in Part D IRMAA alone, and when combined with the top Part B surcharge of $487 per person, the household faces nearly $14,000 annually in Medicare income surcharges before any medical services. The structure creates a survivor trap, as a widow or widower can move from $0 to $83 monthly in Part D IRMAA because single brackets are roughly half the joint thresholds. Beneficiaries can appeal using Form SSA-44 for qualifying life events, but voluntary income events like Roth conversions or home sales cannot be reversed.
