General revenue now funds about half of Medicare. This brief proposes replacing Medicare Part B’s five IRMAA (Income-Related Monthly Adjustment Amount) premium tiers with a linear ramp that ends the taxpayer subsidy at 250,000 of income for single seniors and 500,000 for couples. The reform raises up to 113 billion over 10 years, removes premium cliffs to smooth out marginal tax rates, and leaves premiums unchanged for roughly 90% of Part B enrollees.
