How to Appeal IRMAA

When you can appeal

Medicare sets your IRMAA from your income two years ago. If your income has since fallen because of a qualifying life-changing event — most often retirement or a drop in work hours, but also marriage, divorce, the death of a spouse, or the loss of pension or income-producing property — you can ask Social Security to use your current, lower income instead. You should appeal when the older income on file no longer reflects what you actually earn.

Form SSA-44

The tool for this is Form SSA-44, titled “Medicare Income-Related Monthly Adjustment Amount – Life-Changing Event.” On it you identify the event, the date it happened, and your estimated reduced income for the current (and if needed, the following) year. The form is short, but the supporting documentation is what makes or breaks the request.

Step by step

• Complete Form SSA-44. Check the life-changing event that applies, enter the date, and provide your estimated modified adjusted gross income for the year, along with your filing status.
• Attach proof. Include evidence of both the event and the new income — for example, a signed statement from a former employer or a retirement letter, plus a recent pay stub, a more recent tax return, or other documentation of the reduced income.
• Submit it. Take or mail the completed SSA-44 with your documents to your local Social Security office. You can find the nearest office and current mailing instructions on SSA.gov, or call Social Security to confirm where to send it.

Timeline and what to expect

After you submit, Social Security reviews the form and your documentation and issues a new determination. This typically takes a few weeks to a couple of months. If approved, your Part B and Part D premiums are adjusted to reflect the lower income, and any surcharge already collected earlier in the year may be refunded. If denied, the notice will explain your further appeal rights.

Appeal vs. reconsideration

These two paths are easy to confuse. An appeal on Form SSA-44 is for a genuine life-changing event that lowered your income — you are not saying the data was wrong, just that it is now out of date. A reconsideration is different: it is the route when the IRMAA decision was based on a data error, such as the IRS sharing the wrong year’s return or an amended return that changed your income. If your situation is a true error rather than a life change, you request a reconsideration instead of filing SSA-44.

If you do not qualify to appeal

If your income is simply high and no life-changing event applies, an appeal will not help — the lever then is proactive tax planning. See our IRMAA planning strategies and the full 2026 brackets to understand where you stand.
