Medicare IRMAA Appeal: How to Challenge Your Income-Related Surcharge
If you received an IRMAA surcharge on your Medicare Part B or Part D premiums, you may be able to appeal it due to a life-changing event or incorrect income data.
Medicare IRMAA Appeal: How to Challenge Your Income-Related Surcharge
The Income-Related Monthly Adjustment Amount (IRMAA) is a surcharge added to your Medicare Part B and Part D premiums if your income exceeds certain thresholds. For many beneficiaries — particularly those who recently retired, sold a home, or experienced other income changes — the IRMAA assessment can be based on outdated income data and feel deeply unfair. The good news: you have a formal right to appeal.
What Is IRMAA?
IRMAA is determined by the Social Security Administration (SSA) based on your Modified Adjusted Gross Income (MAGI) from two years prior. For 2025 IRMAA determinations, SSA uses your 2023 tax return.
IRMAA adds a monthly surcharge to your standard Medicare Part B premium ($185/month in 2025) and your Part D plan premium. The surcharge is tiered based on income:
| 2023 Individual MAGI | 2025 Part B Premium Surcharge |
|---|---|
| $106,000 or below | $0 (no IRMAA) |
| $106,001–$133,000 | +$74.00/month |
| $133,001–$167,000 | +$185.00/month |
| $167,001–$200,000 | +$295.90/month |
| $200,001–$500,000 | +$406.90/month |
| Above $500,000 | +$443.90/month |
Married couples filing jointly have higher income thresholds. The IRMAA surcharge for Part D is separate and adds to your plan's base premium.
Grounds to Appeal IRMAA
1. Life-Changing Events
You can request that SSA use more recent income information if you experienced a life-changing event (LCE) that reduced your income since the tax year SSA used. SSA recognizes the following qualifying LCEs:
- Marriage
- Divorce or annulment
- Death of a spouse
- Work stoppage or reduction (retirement, job loss, reduced hours)
- Loss of income-producing property (due to disaster, theft, or foreclosure — not a voluntary sale)
- Loss or reduction of pension income (pension plan termination, bankruptcy of employer)
- Receipt of employer settlement payment (due to employer closing or bankruptcy)
Note: Voluntary decisions such as selling a home or making large Roth conversions are generally not qualifying life-changing events, even if they resulted in a spike in income that year.
2. Incorrect or Outdated Income Data
If SSA used the wrong tax year's data (e.g., used 2022 instead of 2023), used incorrect income figures, or you filed an amended tax return that reduced your income, you can appeal on this basis.
3. SSA Administrative Error
If SSA made a procedural error in computing or assigning your IRMAA, you can appeal.
How to File an IRMAA Appeal
Step 1: Request a Reconsideration
File SSA Form SSA-44 (Medicare Income-Related Monthly Adjustment Amount — Life-Changing Event) within 60 days of receiving your IRMAA determination letter (plus a 5-day mail allowance, so effectively 65 days from the date of the letter).
You can file at your local SSA office, by mail, or in some cases online. The form asks you to:
- Identify which life-changing event applies
- Estimate your current year income (MAGI)
- Provide documentation
Step 2: Provide Documentation
Required documents vary by the type of LCE:

- Divorce: Divorce decree
- Loss of property income: Documentation of the loss event (foreclosure notice, insurance settlement, etc.)
- Pension reduction: Letter from pension administrator confirming reduced benefit
Also provide a self-certification letter estimating your expected current-year MAGI and explaining how the life-changing event reduced your income.
Step 3: SSA Reconsideration Decision
SSA will review your appeal and issue a reconsideration decision. This typically takes 2–3 months.
Step 4: ALJ Hearing (if denied)
If the reconsideration is denied, you can request a hearing before an Administrative Law Judge within 60 days of the denial. The SSA handles these hearings (unlike the Medicare appeals which go to OMHA).
Step 5: Appeals Council and Federal Court
If the ALJ denies the appeal, you can appeal to the SSA Appeals Council and then to federal district court.
Tips for a Successful IRMAA Appeal
File quickly: The 60-day deadline is strict. Do not wait.
Use projected income, not actuals: When you file, SSA uses your estimate of current-year income. Be reasonable and document your estimate with paycheck stubs, retirement account statements, or a CPA's estimate.
Keep detailed records: Keep copies of everything submitted and every communication with SSA.
Request expedited processing if needed: If the surcharge is creating financial hardship, note this in your appeal.
Consult a tax professional: For complex situations involving capital gains, Roth conversions, or business income, a CPA or tax advisor can help you accurately calculate and document your MAGI.
