Early retirement income planning and Medicare's IRMAA

Why income at 63 decides your Medicare premiums at 65, how Roth conversions and asset sales can trigger IRMAA, and how to appeal after retiring.

Medicare uses your tax return from two years earlier to set Part B and Part D premiums. Income at 63 sets your premiums at 65.

Why early retirees get caught

Roth conversions, selling a business or property, and large capital gains can push income over the first IRMAA threshold of $109,000 single or $218,000 joint. The 2026 tiers are in the IRMAA brackets.

Balancing two goals

Low income before 65 helps Marketplace subsidies. Roth conversions in the same years raise income. Many planners spread conversions to stay under a target.

Appealing IRMAA

Retiring counts as a life-changing event. File form SSA-44 with proof of reduced income. Couples can use the same form after the death of a spouse; see Medicare after a spouse dies.
