7. Projected Part B Premiums and IRMAA Surcharges Adjust Upward

Medicare Part B expenses will see modest upward adjustments for 2027. Based on Medicare Trustees projections, the standard Part B monthly premium is expected to rise 3.5% to $209.50, up from $202.90 in 2026.

The annual Part B deductible also climbs to a projected $292, up from $283. These standard costs apply to all beneficiaries receiving outpatient medical care.

Higher-income retirees face additional adjustments through the Income-Related Monthly Adjustment Amount (IRMAA). The 2027 IRMAA surcharges rely on the 2025 tax data you file in 2026.

Projected Part B monthly IRMAA surcharges range from $83.70 to $502.60 above the standard rate. The Social Security Administration notifies affected beneficiaries each autumn regarding these surcharge brackets.
