IRMAA Brackets 2027 (Projected) PROJECTED

12 rows · reviewed 2026-08-05 · QuantCalc Research

Projected — official numbers expected November 2026. CMS has not published the 2027 Medicare premiums or IRMAA thresholds. The 2026 figures were released on November 14, 2025, and the 2027 release is expected on a similar schedule. Every threshold on this page is our own projection from the statutory indexing formula, and the last input to that formula — the August 2026 CPI-U reading — is not published until September 2026. Treat these as planning estimates, not filing figures.
