Medicare IRMA Premium Reduction calculator

Tim White Updated by Tim White

Medicare recipients pay a basic premium of $202.90 per month in 2026. If they have a higher MAGI (AGI plus tax exempt interest) then they may be subject to an Income Related Monthly Adjustment (IRMA) amount . The MAGI used by Medicare is for 2 years prior. So for 2026, it uses 2024 MAGI. This can force taxpayers to pay an IRMA even after their income goes back down.

However, form SSA-44 allows them to request an IRMA reduction if they have one of the life changing events specified on the form, and they have a lower MAGI in 2026 and can provide documentation to back it up. See the form and instructions.

This module calculates the monthly Medicare premium based on the 2024 MAGI and the reduced amount based on an estimate of the 2026 MAGI. It also shows the total savings that would result if the request is accepted.

NOTE: You specify the month in 2026 that the event took place if the reduction only applies to part of the year. Also for MFJ filers, the premiums would apply to both spouses if they are both on Medicare. Be sure to specify if 1 or 2 taxpayers are on Medicare.
