How Do I Appeal IRMAA? (Form SSA-44)

Why you were charged IRMAA in the first place

IRMAA (the Income-Related Monthly Adjustment Amount) is a surcharge added to your Medicare Part B and Part D premiums when your income is above a threshold. The part that catches people off guard is the timing: Medicare looks back two years. Your premium this year is based on the tax return you filed two years ago.

So a year when you sold a property, took a large distribution, or were still working at full salary can raise your Medicare premium long after your income has dropped. If you retired last year, the surcharge is being calculated on the income you earned while you were still working.

The eight life-changing events SSA accepts

Form SSA-44 lists exactly eight. Your situation has to fit one of them:

The mistake that gets most appeals denied

A one-time spike in income is not a life-changing event. This surprises almost everyone.

If your income two years ago was unusually high because you did a Roth conversion, sold appreciated stock, sold a rental or a business, or took a large one-time IRA distribution — that is not on the list. SSA will deny the appeal, and they are applying the rule correctly when they do.

The exception worth knowing: if you retired and did a large conversion in the same year, you may still have a valid appeal — but you file it on the work stoppage, not on the conversion. Lead with the retirement date and the employer letter.

I wrote this guide because the appeal itself is two pages, but almost every denial I see comes down to the same avoidable thing. Put your name below and I’ll send you the one-page filing checklist — which event to check, the exact document SSA wants for each one, and the reason that gets appeals thrown out. If your situation doesn’t fit neatly, reply to the email and tell me what happened; I read them.

What the surcharge actually costs

IRMAA is not a percentage. It is a set of flat tiers: cross a threshold by one dollar and you pay the entire next tier, all year. That cliff structure is what makes IRMAA feel so unfair, and it is also why appeals matter so much — there is no partial relief and no gradual phase-in. You are either in a tier or you are not.

The surcharge applies to both Part B and Part D, billed monthly, and it is charged per person. Two spouses on Medicare in the same household each pay their own. Because the thresholds and amounts are reset by CMS every year, the only reliable way to see where you actually land is to run your own numbers against the current year’s brackets rather than working from a figure someone quoted you last year.

A typical case

Someone retires in March. For that year their income is modest — two months of salary and then Social Security. But their Medicare premium two years later is calculated on the last full year they worked, when they earned a complete salary plus a bonus. The bill arrives, and it is several hundred dollars a month higher than they budgeted for, based on money they have not earned in two years.

This is the textbook SSA-44 case, and it is the one the form was designed for. The event is work stoppage. The proof is a letter from the employer or the pension award letter showing the retirement date. The estimated income is what they actually expect to make now, not what the old return says.

If you have not triggered it yet

The two-year lookback cuts both ways. If you are planning something that will spike your income — a Roth conversion, selling a rental, exercising options — you can see the Medicare consequence two years before it lands, which is enough time to do something about it.

The common approaches are to spread a conversion across several smaller years instead of one large one, to time a sale into a year you were already going to be over a threshold anyway, or simply to accept the surcharge knowingly because the underlying move is still worth it. All three are legitimate. What causes the damage is not knowing the cliff was there.

Married couples

The thresholds for married filing jointly are higher than for a single filer, but not always double, and the surcharge is still assessed on each spouse individually. Two practical consequences follow.

First, a successful appeal is worth roughly twice as much to a couple as to a single person, for the same two pages of paperwork. Second — and this is the hard one — a widow or widower moves from the joint thresholds to the single thresholds, usually the year after the death. Income barely changes, but the bracket you are measured against gets much tighter. That situation has its own name and its own set of consequences beyond Medicare, which we cover in the widow’s penalty guide.

How to file, step by step

1. Download Form SSA-44 from ssa.gov (search “SSA-44”). It is two pages.
2. Check the one event that applies and write the date it happened.
3. Enter your estimated income for the year the reduction took effect, plus the tax-filing status you expect to use.
4. Attach your proof — the document from the table above. Copies are fine; do not send originals.
5. Submit it. Mail it to your local Social Security office, or bring it in person. Calling 1-800-772-1213 first to confirm where to send it saves time.

There is no filing fee at any stage.

Timing

You can file as soon as the life-changing event has happened — you do not have to wait for a bill or for the next tax year. If you have already received a notice telling you what your premium will be, file promptly; appeals tied to a specific determination are generally expected within 60 days of that notice.

If the surcharge has already been deducted and your appeal succeeds, the correction is applied back to the start of the period it covers.

If SSA denies it

A denial is not the end. You can request reconsideration, and beyond that there is a hearing before an Administrative Law Judge. Most denials at the first stage come down to one of two things: the reason given was not one of the eight events, or the supporting document was missing. Both are fixable on the second attempt.

What this is worth

IRMAA is assessed per person. For a married couple where both are on Medicare, a successful appeal removes the surcharge for both — so the amount at stake is roughly double what a single filer sees, for the same two pages of paperwork.

It also resets annually. Winning an appeal for this year does not prevent a surcharge next year if your income rises again, and it does not carry forward on its own.
