How to appeal IRMAA and choose the right route
Appeal IRMAA and most people reach for Form SSA-44 — but SSA’s manual lists only
eight qualifying events, and four other routes need no form at all.
In This Article
Your Medicare notice says your 2026 premium includes an income-related monthly adjustment amount, built from your 2024 income rather than today’s.
What you file depends on what changed. If you retired, cut your hours, married, divorced, lost a spouse, or lost pension income, Form SSA-44 is your route. If the income figure itself is wrong — an amended return, an IRS error, the wrong filing status — a different request applies.
If a one-time event lifted your 2024 income, such as a Roth conversion or a property sale, there is no relief. Section seven explains why.

SSA-44 is not technically an appeal
Form SSA-44 requests a new initial determination, not an appeal. That difference decides what you file.
What a new initial determination means
Social Security’s manual, POMS HI 01120.001, defines it as a fresh decision that does not reopen the earlier one. If you meet the criteria, the manual says no appeal is needed. The form is optional; you can request one verbally or in writing.
How your income figure was built
Modified adjusted gross income is adjusted gross income from line 11 of Form 1040, plus tax-exempt interest from line 2a. It sets a surcharge on two of the five separate bills Medicare sends.
🔍 How It Works: Social Security uses the newest return the IRS has processed, two years back. Form SSA-44, edition 12-2025, confirms your 2024 return set your 2026 premium. This year’s income sets 2028.
The eight events that qualify, and four other routes
Social Security recognises exactly eight life-changing events and calls the list exclusive: death of a spouse, marriage, divorce or annulment, work reduction, work stoppage, loss of income-producing property, loss of employer pension, and an employer settlement payment.
Four further situations allow the same request with no life-changing event.
| Your situation | What to request | Key detail |
|---|---|---|
| A qualifying life-changing event | New determination, SSA-44 | Event proof, newer income |
| You amended the return used | New determination, no form | Return, IRS acknowledgement |
| The IRS data is wrong | New determination, no form | Get IRS proof first |
| Three-year-old data was used | New determination, no form | Signed two-year-old return |
| Filed separately, lived apart | New determination, no form | Form 1040 or attestation |
| You dispute the determination | Reconsideration, SSA-561-U2 | 60 days from receipt |
Source: SSA POMS HI 01120.001 and HI 01120.005, verified September 2026.
The event may have happened at any time in the past, which matters for a surcharge still set by a joint return after a spouse dies.
Filling out Form SSA-44, step by step
Form SSA-44 has five steps, and two decide whether the request succeeds.
- Step 1 — check your event, with month and year.
- Step 2 — enter the newer tax year, adjusted gross income, tax-exempt interest, filing status.
- Step 3 — estimate next year if income falls further.
- Step 4 — attach your evidence.
- Step 5 — sign, under penalty of perjury.
Choosing the right tax year in Step 2
Use this year if income was not reduced until now, or fell last year and drops again. Use last year if it fell then and will be no lower now. Your event date must fall in that year or earlier.
Why Step 3 is not optional
⚠️ Costly Mistake: Leave Step 3 blank and the manual directs staff to carry your Step 2 estimate into the following year, so a retiree whose income keeps falling overpays a second year. Our income tax calculator gets both estimates close enough.
Proof, where to send it, and the deadlines
The Social Security Administration names one document per event, and needs the newer year’s income too.
| Life-changing event | Evidence required |
|---|---|
| Marriage | Certificate or certified record |
| Divorce or annulment | Certified copy of the decree |
| Death of a spouse | Certified death certificate |
| Work stoppage or reduction | Employer statement, pay stubs, or your own statement under penalty of perjury |
| Loss of income-producing property | Adjuster’s statement or government letter |
| Loss of pension income | Letter from the plan administrator |
| Employer settlement payment | Employer letter with the terms |
Source: Form SSA-44, edition 12-2025, page 8.
For income, send a signed return or IRS transcript; an estimate is accepted if you have not filed.
Three dates that carry consequences
You have 30 days to produce evidence, extendable to 90 on request, or the request is dismissed. To reach back into the prior premium year, the event must fall in that year’s last three months and your request must arrive by 31 March. A reconsideration is due within 60 days of receipt, presumed five days after the notice date.
💡 Expert Note: Social Security publishes no processing-time standard for these requests. Figures like “30 to 45 days” circulate online without a source behind them, so treat the 30-day evidence window as the only clock you control.
The form prints no mailing address: use the office locator, the address on your notice, or call 1-800-772-1213.
✅ Action Step: Ask a State Health Insurance Assistance Program counsellor, free in every state, one question before sending: “Does my event date support the tax year in Step 2?”
What a granted request is worth in 2026
The standard 2026 Part B premium is $202.90 a month, with a $283 annual deductible. Above the thresholds below, a surcharge is added to Part B and Part D.
| 2024 MAGI, single | 2024 MAGI, joint | Monthly Part B + Part D | Key detail: annual cost |
|---|---|---|---|
| $109,000.01–$137,000 | $218,000.01–$274,000 | $81.20 + $14.50 = $95.70 | $1,148.40 |
| $137,000.01–$171,000 | $274,000.01–$342,000 | $202.90 + $37.50 = $240.40 | $2,884.80 |
| $171,000.01–$205,000 | $342,000.01–$410,000 | $324.60 + $60.40 = $385.00 | $4,620.00 |
| $205,000.01–$499,999.99 | $410,000.01–$749,999.99 | $446.30 + $83.30 = $529.60 | $6,355.20 |
| $500,000 and above | $750,000 and above | $487.00 + $91.00 = $578.00 | $6,936.00 |
Monthly amounts: CMS, “2026 Medicare Parts A & B Premiums and Deductibles,” November 14, 2025. Annual figures are our calculation. Every threshold sits in the full 2026 bracket table.
🔍 How It Works: The annual column is the two monthly surcharges added together, then multiplied by twelve.
📊 Data Point: Roughly 8% of people with Part B pay an income-related amount — Source: CMS, November 2025.
A single filer with 2024 income of $175,000 who stopped work in March 2025 pays $385.00 a month in surcharges on top of the standard Part B premium and their drug plan — $4,620 across 2026. These are per-person amounts, so a couple pays twice.
Why most IRMAA requests get rejected
Two patterns account for most failures, and the first cannot be fixed.
One-time income does not qualify
Social Security’s manual names the non-qualifying events: capital gains from a property sale, lottery and casino winnings, conversion of an IRA, and cashing bonds. It also excludes higher medical or living expenses, lost alimony, and a voluntary property sale. A 2024 Roth conversion or property gain is a one-year cost.
If the return was wrong rather than merely high, ask a CPA: “Would amending this change the income Social Security is using?” That route runs through Form 1040-X, and our capital gains tax calculator shows what the gain added.
Your spouse files separately
⚠️ Costly Mistake: The manual states a life-changing event finding is not extended to a non-reporting spouse. If you both pay the surcharge, one approved request fixes one premium.
IRMAA appeal questions, answered
1. What is IRMAA?
An income-related monthly adjustment amount added to Medicare Part B and Part D premiums above set income thresholds.
2. Can you appeal IRMAA?
Yes, though most people should request a new initial determination instead; Social Security’s manual says an appeal is unnecessary.
3. What are the eight life-changing events for IRMAA?
Death of a spouse, marriage, divorce, work reduction, work stoppage, lost income-producing property, lost employer pension, employer settlement payment.
4. Is a Roth conversion a life-changing event for IRMAA?
No. Social Security lists IRA conversion as non-qualifying, with capital gains and lottery winnings. Ask a CPA about amending.
5. How do I fill out Form SSA-44?
Five steps: name the event and date, give the newer year’s income, estimate next year, attach evidence, sign.
6. What proof does SSA need for an IRMAA appeal?
Evidence of the event — certificate, decree, employer statement or pension letter — plus a signed return or income estimate.
7. Where do I send Form SSA-44?
The form prints no mailing address. Use Social Security’s office locator, or the address printed on your IRMAA notice.
8. How long does an IRMAA decision take?
Social Security publishes no processing-time standard, so your only fixed clock is 30 days to supply evidence.
9. What is the deadline to appeal IRMAA?
Sixty days from receipt for reconsideration, presumed five days after the notice date. Retroactive relief ends 31 March.
10. Does my spouse need a separate SSA-44?
Yes. Social Security does not extend a life-changing event finding to a non-reporting spouse, so both must file.
11. What if Social Security denies my request?
Four levels follow: reconsideration, an OMHA hearing, Medicare Appeals Council review, and finally federal court.
Your next step
Find your situation in the route table, then gather the document your event requires. Download Form SSA-44, edition 12-2025, and call 1-800-772-1213 for a field office appointment — before 31 March if a prior premium year is in play.
