Quick Read – Medicare’s IRMAA surcharge can add nearly $12,000 per year to a retired couple’s costs based on income earned two years earlier. – Mandatory RMDs starting at 73 count fully toward MAGI and can push even modestly situated retirees into an unexpected IRMAA bracket. -…
alified charitable distributions of up to $108,000 per year satisfy RMDs without counting as taxable income, directly reducing MAGI exposure. – Most retirees assume their Medicare premiums are fixed, budget for the standard Part B cost, and move on. What catches higher-income retirees off guard is a separate charge that can quietly add thousands of dollars a year to healthcare costs
It is called IRMAA, and understanding how it works is one of the more valuable things a retiree can do before the bills start arriving. IRMAA stands for Income-Related Monthly Adjustment Amount, and it is a surcharge added on top of the standard Medicare Part B and Part D premiums for enrollees whose income exceeds certain thresholds. The surcharge is not based on what you earn this year, it is based on your modified adjusted gross income from two years earlier, which means the retirement income decisions you make today can affect your Medicare costs two years down the road.
How IRMAA Brackets Work in 2026 The standard Part B premium in 2026 is $202.90 per month, and for retirees whose 2024 modified adjusted gross income exceeded $109,000 as a single filer, or $218,000 for a married couple filing jointly, that standard premium becomes a starting point, not the final number. The brackets escalate quickly as a single filer with 2024 MAGI between $109,000 and $137,000 pays $284.10 per month for Part B rather than the standard $202.90. If you move into the next bracket, from $137,000 to $173,000, the premium climbs to $405.80
