Medicare Part B Premium 2027: What to Expect and Who Pays More

The 2026 Medicare Trustees Report projects a 2027 standard Part B premium of $209.50 a month, up from $202.90 in 2026. That’s about a 3.25% increase, and it isn’t final. CMS typically announces official premiums, deductibles and IRMAA brackets in the fall, usually around November. Most enrollees will pay the standard amount, but higher earners pay more through the Income-Related Monthly Adjustment Amount (IRMAA). The 2027 brackets use modified adjusted gross income from your 2025 tax return. Here’s what to expect and who is likely to pay more.
