What Is IRMAA and Why Might You Need to Appeal?
IRMAA — the Income-Related Monthly Adjustment Amount — is a surcharge added to your standard Medicare Part B and Part D premiums if your income exceeds certain thresholds. In 2026, the surcharge kicks in for individuals with a Modified Adjusted Gross Income (MAGI) above $109,000, or married couples filing jointly above $218,000.
Here's the catch: IRMAA is based on your income from two years ago. Your 2026 IRMAA is calculated using your 2024 tax return. If your income has dropped significantly since then due to retirement or another life event, you may be paying IRMAA based on a higher income than you currently earn.
That's where the appeal process comes in. You can see the current brackets and the dollar amounts at stake on our IRMAA Brackets 2026 page. The Part B surcharge alone can range from $81.20 to $406.00 per month above the standard premium — so the savings from a successful appeal can be substantial.
| 2026 MAGI (Single) | Part B Premium (monthly) | IRMAA Surcharge |
|---|---|---|
| $109,000 or less | $202.90 | $0 |
| $109,001 – $137,000 | $284.10 | +$81.20 |
| $137,001 – $163,000 | $365.30 | +$162.40 |
| $163,001 – $183,000 | $446.50 | +$243.60 |
| $183,001 – $500,000 | $527.70 | +$324.80 |
| Above $500,000 | $608.90 | +$406.00 |
What Is the SSA-44 Form?
Form SSA-44, titled "Medicare Income-Related Monthly Adjustment Amount — Life-Changing Event," is the official form used to request that Social Security recalculate your IRMAA using more recent income data due to a qualifying life event. The form is published and maintained by the Social Security Administration.
You can download the SSA-44 directly from SSA.gov (PDF). It cannot be submitted online as of 2026 — you must submit it in person at a Social Security office, by mail, or by fax.
The 8 Qualifying Life-Changing Events for IRMAA Appeal
The SSA-44 appeal process is not available for everyone. You must have experienced one of these specific life-changing events that reduced your income:
- Marriage — Your marital status changed and your combined income is lower in the current tax year.
- Divorce or annulment — Your marriage ended, affecting your MAGI filing status.
- Death of a spouse — Your spouse passed away, changing your income and filing status.
- Work stoppage — You stopped working entirely (commonly: retirement).
- Work reduction — You significantly reduced your working hours or salary.
- Loss of income-producing property — Property that was generating income was lost due to a natural disaster, fraud, or other event beyond your control.
- Loss or reduction of employer pension — Your pension income stopped or was significantly reduced (for example, due to plan bankruptcy).
- Employer settlement payment — You received a one-time settlement or payment from an employer or former employer that inflated your MAGI in the base year.
Step-by-Step: How to File an IRMAA Appeal
- Confirm you have a qualifying life event. Review the list above. If none of the 8 events applies, the SSA-44 process is not available to you — but your IRMAA will automatically recalculate when the IRS sends SSA your new tax return.
- Download Form SSA-44. Go to SSA.gov/forms/ssa-44.pdf and download the most current version of the form.
- Gather your supporting documentation. You'll need proof of the life event (retirement letter, death certificate, divorce decree, etc.) and your estimated current-year income. SSA will need to see documentation that supports both the event and the income reduction.
- Complete the SSA-44. Fill in your name, Social Security number, Medicare number, the qualifying life event, the event date, and your estimated MAGI for the current year. The form has instructions — follow them carefully.
- Submit the form. Take the completed form and all supporting documents to your local Social Security office in person, or mail them to your local office. Call 1-800-772-1213 to find your nearest office or to ask about fax submission.
- Follow up after 30 days. SSA aims to process appeals within approximately 30 days. If you haven't received a response, call SSA or visit your local office.
- Receive SSA's decision. SSA will send a written determination. If approved, your Medicare premium will be adjusted — usually retroactively to the date of your life event or the beginning of the year, depending on the circumstances.
What Happens If Your Appeal Is Denied?
If SSA denies your IRMAA appeal, you have formal appeal rights. Within 60 days of receiving the denial, you can:
- Request reconsideration: Ask SSA to review the decision again with the same evidence or additional documentation.
- Request a hearing: If reconsideration is denied, you can request a hearing before an Administrative Law Judge (ALJ).
- Appeal to the Appeals Council: If the ALJ rules against you, you can appeal to the Social Security Appeals Council.
- Federal court: As a last resort, you can challenge the decision in federal district court.
In many cases, denials result from incomplete documentation rather than ineligibility. Resubmitting with stronger supporting evidence often resolves the issue.
