How do I appeal IRMAA after retirement?

You appeal IRMAA after retirement by filing Form SSA-44 with Social Security, telling them you stopped working, and giving them an estimate of what you will actually earn this year. Retirement is one of the eight life-changing events the rules recognize, and when the request is approved, Social Security sets your Part B and Part D premiums from your retired income instead of the working-year tax return it would otherwise use. The form is two pages, it can be filed online, and for a couple who just stopped drawing two salaries it is routinely worth more than a thousand dollars a year.

The reason it matters right now is the calendar. If you retired in 2026, the letter arriving late this fall will set your 2027 premium from your 2025 return — your last full year of work. Here is what that letter is going to say, how to answer it, and why I fill this form in with more households in north Peoria than anywhere else in the service area.

Why a retiree gets a surcharge in the first place

IRMAA — the income-related monthly adjustment amount — is the extra Medicare charges above the standard premium when your income is over a line. For 2026 the line is $109,000 of modified adjusted gross income for a single filer and $218,000 for a couple filing jointly. Cross it by a dollar and the Part B premium goes from $202.90 to $284.10 a month, and Part D picks up its own surcharge of $14.50 on top. Both are per person, so a married couple pays it twice. If you want the full mechanics, IRMAA explained covers the brackets and the cliff.

The part that catches retirees is the lookback. Social Security does not ask what you earn now. It takes the most recent tax return the IRS has processed — normally the one from two years earlier — and uses that. Your 2026 premium was set from your 2024 return. The 2027 premium, announced in a letter that usually lands in late November or December, will be set from your 2025 return.

So picture someone who worked all of 2025, retired in the spring of 2026, and now lives on Social Security and a modest draw from an IRA. Their 2025 return shows a full salary. Their 2027 Medicare premium will be priced as though they still earned it. And 2028 is set from the 2026 return — the one with a quarter of a salary and the payout of unused leave in it — which can hold them over the line for a second year. Up to two years of surcharge on income that stopped.

That is the situation Form SSA-44 exists to fix.

The eight events, and the one that applies to you

Social Security will recalculate only for a life-changing event, and it lists exactly eight:

1. Marriage
2. Divorce or annulment
3. Death of a spouse
4. You or your spouse stopped working
5. You or your spouse reduced your work hours
6. Loss of income-producing property, through a disaster or another event beyond your control
7. Loss of pension income
8. An employer settlement payment because the employer closed or went bankrupt

Retirement is number four. So is a spouse retiring, which matters for a couple where one income stopped and the other did not — the household return still dropped, and that is the number Social Security prices from. Going from full time to part time, or from running a business to consulting a few days a month, is number five. Selling a business outright is a work stoppage as well.

What is not on the list matters just as much. A big year followed by an ordinary one does not qualify. Neither does a Roth conversion, a home sale, or a capital gain you took to fund the move to Arizona. Those surcharges are generally paid for the one year they apply and then they go away. The exception is when a genuine event happened in the same window — you retired and sold the house — because then you file for the retirement and the income estimate you give covers the whole picture.

What the form actually asks

SSA-44 has five steps, and the whole thing fits on two pages once you know what goes in each box.

Two details in step two trip people up. The income figure is MAGI as Medicare defines it — adjusted gross income plus tax-exempt interest — so municipal bond income counts, and so does the taxable part of your Social Security, your pension, your IRA withdrawals and any required minimum distributions. Estimate the whole year, not the months since you retired. And the year you name is your choice between the year of the event and the year after it. If you retired in March, your 2026 income still has a quarter of a salary and perhaps a payout of unused leave in it; 2027 may be the better year to point at. You are allowed to use either, and step three lets you tell them about both.

Step four is where the online option earns its keep. Social Security now lets you sign in, complete the form and upload the evidence electronically, which removes the trip to the office and the scanning queue on the other end. Fax and mail still work. So does calling and asking a representative to take the request over the phone, though you will still be asked for the paperwork.

What happens after you file

While the request is pending, you keep paying whatever the letter said — the surcharge comes out of your Social Security check if you draw one, or arrives as a quarterly bill if you do not. Nothing about the request pauses that.

When it is approved, Social Security issues a new determination, resets the premium from your estimate, and refunds the surcharge you overpaid for the months of that year already billed. In practice the answer comes back in somewhere between several weeks and a few months, and the refund follows it. Keep a copy of everything you sent, and note the date.

Then there is the year after. The estimate you gave is exactly that, and Social Security will eventually see your real return. If you estimated in good faith and the real figure came in close, nothing happens. If the real figure came in over the line — a larger IRA draw than planned, a stock sale you forgot — they can reassess, so the estimate is worth doing carefully rather than optimistically.

And it does not have to be repeated forever. Once your first full retired-income return has been filed and worked through the IRS, Social Security picks it up on the ordinary two-year cycle and the surcharge disappears without another form, provided that income is under the line. SSA-44 bridges the gap years. It is not an annual chore.

The 2026 brackets, so you can see what is at stake

These are the 2026 figures, per person, per month. CMS publishes the 2027 brackets in mid-November, and they usually move up a little.

Joint filers double each of the first four thresholds — the line starts at $218,000 — and the top tier begins at $750,000. A couple whose final working year put them in the second tier, and who now live comfortably under the first line, are paying the gap between $405.80 and $202.90 plus $37.50 on Part D, each, every month, until somebody files. The IRMAA estimator will show you where a given income lands.

One thing the letter does not make obvious: the Part D surcharge applies whether you have a stand-alone Part D plan or drug coverage folded into a Medicare Advantage plan, and it is billed by Social Security, not by the plan. A plan advertised at no monthly premium still carries the Part D IRMAA if your income says so. Same for a Medicare Supplement household, where the surcharge sits on top of the Medigap premium rather than replacing any part of it.

Why this is a north Peoria question

I fill this form in with more households in 85383 than anywhere else I work, and the reason is who moves there.

Vistancia, Trilogy at Vistancia and Blackstone are full of couples who retired and relocated in the same twelve months. The pattern is nearly always the same: a last full working year somewhere with a higher cost of living, a sale of the old house, a move down the Loop 303 corridor, and then a first year in Arizona on pension, Social Security and portfolio income that comes to a fraction of what the final salary did. That last working return is precisely the one Social Security uses to price their first year or two of Medicare here. They are the textbook SSA-44 case, and very few of them have heard of the form, because the person who handled their benefits at work is no longer in the picture and the Medicare paperwork arrived at a new address.

The seasonal households add a wrinkle. A couple in Trilogy who spend the summer in Michigan or Minnesota often have a tax preparer up there and a financial advisor down here, and the IRMAA letter — which comes from Social Security, not from either of them — falls between the two. Nobody is wrong; it is just that nobody’s job was to open it. If that is your household, the fix is simple: whoever prepares the return should see the letter, because the estimate on SSA-44 has to reconcile with what they file next spring.

On the 85345 side of the city and in Westbrook Village the question comes up differently. Those households are more often ten years into retirement with income already under the line, and when a surcharge appears it is usually a one-time event — a property sale, a large withdrawal — that does not qualify for the form and simply has to be paid for a year. The distinction between the two ends of Peoria is the distinction between “file SSA-44” and “check the arithmetic and wait it out,” and it is worth knowing which one you are before you spend an afternoon on it. Medicare in Peoria has the rest of the local picture.

What to do this fall, in order

1. Work out your 2026 and 2027 MAGI now, all sources, before the letter arrives. Salary and payouts for the part of the year you worked, Social Security’s taxable share, pension, IRA and 401(k) withdrawals, dividends, capital gains, and tax-exempt interest. If you are unsure, the preparer who will file the return is the right person to ask, and this is a tax question first.
2. Gather the evidence. A retirement letter, a severance agreement, a final pay stub or a signed statement from the employer confirming the last day. If you closed a business, the paperwork that shows it.
3. Watch for the letter in late November or December. Read the year it says it used. If that year is your last working year, it is the letter this article is about.
4. File SSA-44 — online through your my Social Security account if you can — naming the work stoppage and the lower year. Do not wait for January; the request can go in as soon as you have the letter.
5. Keep copies and the filing date, and if the response has not come back in a couple of months, follow up.

If you are not retired yet but the date is set for 2027, put a note in the calendar for the fall of that year. The same letter will arrive, and the same form will fix it.

The short version

• Retirement is a qualifying life-changing event. File Form SSA-44 and Social Security prices your Medicare from your retired income instead of your last working return.
• The letter this fall sets your 2027 premium from your 2025 return. Without the form, 2028 will be priced from 2026 the same way.
• You choose the year — the year you retired or the year after — and you estimate the whole year’s MAGI, tax-exempt interest included.
• Evidence is a retirement letter or an employer statement. The form can be filed online, faxed, mailed or handled by phone.
• One-time income does not qualify. A conversion, a home sale or a good market year is paid for one year and then drops off on its own.
• It is not an annual filing. Once your first retired-income return is in the system the surcharge clears on the ordinary cycle.

If you would rather have someone look at it with you

The form is short, but the estimate on it has consequences, and the difference between the year of the event and the year after can be the difference between clearing the surcharge and clearing half of it. I go through this with clients every December, and it is a twenty-minute conversation: the letter, the last working year, what this year and next actually look like, and which year to name. The tax detail belongs to your tax advisor. The Medicare side is mine, and the review costs nothing.

The office is in Anthem, roughly 25 minutes from north Peoria out the Carefree Highway and down Lake Pleasant Parkway, and most of this happens by phone anyway. Call (602) 844-6002 or book a time — and if you call or text, that is your consent for me to reply the same way.

And if the letter has already arrived and it names a year you spent working, do not simply pay it. That is the one Medicare bill that comes with a form for saying no.
