How to Appeal IRMAA After Retirement in Utah (Form SSA-44)

Retiring counts. Social Security's own regulation lists "you or your spouse stop working or reduce the hours you work" as a major life-changing event, which means you can ask it to set your Medicare premium from this year's income instead of the return from two years ago. Here is what the rule actually says, what it excludes, when to file, and what to bring.

The surcharge shows up at the worst possible moment. You retire, your paycheck stops, and a few months later Social Security tells you your Medicare premium is going up — because it is looking at the tax return from two years ago, when you were still working. Every fall I hear a version of this from someone in Moab, St. George or the Wasatch Front who has just left a good job at the University, the mine, a practice or a business they built. The premium is not wrong. It is just stale. And the fix has a form, a regulation and a deadline, none of which anyone sends you.

What IRMAA is and why the number is two years old

IRMAA is the income-related monthly adjustment amount — an extra charge added to your Part B and Part D premiums when your modified adjusted gross income is above a threshold. Per CMS, it affects roughly 8% of people with Part B, and for 2026 it starts above $109,000 for a single filer and $218,000 for a couple filing jointly.

Source: CMS — 2026 Medicare Parts A & B Premiums and Deductibles (Nov 14, 2025). 2026 premiums are set from your 2024 federal return. Married filing separately uses a different schedule.

The two-year lag is the whole problem. Social Security uses the most recent return the IRS has handed it, which for 2026 premiums is usually the 2024 return. If you retired in 2025 or 2026, the income on that return may bear no resemblance to what you are living on now. The regulation's answer is not an "appeal" in the courtroom sense; it is a request that Social Security use a more recent tax year. That distinction matters, because it means you are not arguing that the surcharge was miscalculated — you are supplying a newer number.

The seven events that qualify — verbatim from the regulation

Form SSA-44 lists the events with checkboxes, but the form implements a regulation, and the regulation is the thing worth reading. 20 CFR 418.1205, "What is a major life-changing event?":

Sources: 20 CFR § 418.1205 — What is a major life-changing event? (eCFR) · 20 CFR § 418.1210 — What is not a major life-changing event?.

Read item (e) carefully, because it is where the most confident appeals fail. A loss of income-producing property qualifies only when it "is not at the direction of you or your spouse (e.g., due to the sale or transfer of the property) and is not a result of the ordinary risk of investment." The regulation's own examples are a disaster-declared property loss, livestock or crops lost to disease, arson, and investment property lost to a third party's fraud. Selling the rental in St. George is the opposite of that. So is a bad year in a brokerage account — § 418.1210(b) specifically excludes "the loss of dividend income because of the ordinary risk of investment."

The other line to notice is that every event says "you or your spouse." If your husband retired and your own income never changed, the household's joint MAGI still dropped, and the request is still yours to make.

"Significant" has a definition, and it is the tier line

The event alone is not enough. § 418.1201 requires that it "results in a significant reduction in your modified adjusted gross income," and then defines the word: a significant reduction "is one that results in the decrease or elimination of your income-related monthly adjustment amount." § 418.1215 says the same thing from the other side — the decrease has to lower the percentage tier you pay, or drop you below the threshold entirely.

So the arithmetic is done against the table above, not against your feelings about the paycheck. A couple whose joint income fell from $330,000 to $280,000 has lost a lot of income and stayed in the same tier; the regulation calls that not significant. A couple who fell from $300,000 to $150,000 has crossed two lines, and the difference at 2026 rates is $240.40 a month per person — $5,769.60 a year for the two of them, which is our arithmetic on the CMS table, not a number CMS publishes. That is the size of the check this form is about.

Which year to ask for — and why it changes the effective date

§ 418.1225 lets you offer any tax year more recent than the one Social Security used, and the regulation "will always ask you for your retained copy of your filed Federal income tax return for the more recent year." For most retirees the year you want is the current one, and you have not filed it yet, which the rule anticipates: you provide "evidence that is equivalent to a copy of a filed Federal income tax return" — in practice an estimate with a signed statement.

The choice of year sets the effective date. Under § 418.1230(a), when the event has already reduced this year's income, the determination "is generally effective on January 1 of the year in which you make your request." Under paragraph (c), when your income "will not be significantly reduced ... until the year following the year you make your request," the determination is effective January 1 of that following year instead. In plain terms: someone who retired in February 2026 asks Social Security to use estimated 2026 income and gets relief back to January 2026. Someone who retires in November 2026, with ten months of salary already banked this year, may not clear the tier line for 2026 at all — and should ask for 2027 to be set from estimated 2027 income.

The deadline nobody mails you

§ 418.1310(a)(4): "You may make such a request at any time during the calendar year in which you experience a significant reduction in your modified adjusted gross income caused by a major life-changing event." And for late-year events: "When you have a major life-changing event that occurs in the last 3 months of a calendar year ... you may request that we make a new initial determination based on your major life-changing event from the date of the event until March 31 of the next year."

Miss that, and the regulation sends a late request to a good-cause review under paragraph (b) — possible, not promised. The practical rule for a Utah retiree: file in the year you retire, and if you retire in the fourth quarter, file by March 31.

What to bring: the evidence rules

For retirement, § 418.1255(d) asks for "evidence documenting the change in work activity," and gives examples: "documents we can corroborate such as a signed statement from your employer, proof of the transfer of your business, or your signed statement under penalty of perjury, describing your work separation or a reduction in hours." A retirement letter from a Utah employer or a URS or PEHP benefit-start notice does the job. A sole proprietor who closed the doors can use the business transfer documents or the sworn statement.

For the income, § 418.1265 prefers your retained copy of the filed return for the year you want used; when that does not exist yet, "equivalent evidence" plus "your signed statement under penalty of perjury that the information you provide is true and correct." Be realistic on the estimate. If it turns out low, § 418.1240 expects you to tell them, and the adjustment runs the other way. One more line from § 418.1270 for anyone planning an amended return: Social Security "will not accept a correction or amendment of your income tax return without a letter from IRS acknowledging the change."

Three other doors in the same regulation

The life-changing-event request is (a)(4) of § 418.1310. The same section has three siblings that fit specific situations:

1. Social Security used a three-year-old return. If the IRS handed over the return from three years back instead of two, you can give them the two-year-old one under (a)(1), and they adjust back to January.
2. You amended a return. Under (a)(2), an amended return for the year they used replaces the original — with the IRS acknowledgment letter, per § 418.1270.
3. The IRS data was simply wrong. Under (a)(3) and § 418.1335, proof from the IRS of a correction replaces the bad number, and corrections are retroactive.

And if the answer is no: § 418.1320 says an initial determination "is binding unless you request a reconsideration" within the time period stated in your notice. Read the notice; the clock is printed on it.

How long the lower number lasts

This is the question people ask after the good news arrives. § 418.1235: Social Security keeps using your more recent year until it "receive[s] your modified adjusted gross income from IRS for the more recent tax year we used or a later tax year," until the year you gave it is "more than 3 years prior" to the premium year, until you file another event request, or until you report a change. In the ordinary retirement case that means the estimate carries you across the gap, and then your first real full-year retirement return takes over from the IRS on its own. You do not have to file the form every year unless something else on the list happens.

The Utah wrinkle: a lot of retirements here are not clean stops

Utah retirees consult, ranch, run a short-term rental in Grand County, or go back part-time at the district. None of that disqualifies you — the event is "stop working or reduce the hours you work" — but it makes the income estimate the part to get right. A reduction that leaves you in the same tier is not significant under § 418.1215, and an estimate that ignores the consulting income will be corrected against you later. Put the real number on the form. If the real number does not cross a tier line, the honest answer is that there is nothing to file this year, and the fix is timing the next Roth conversion or property sale for a year that keeps you under the line. For the interplay, our Roth conversion timing and home sale posts cover the two mistakes we see most.

Two things this page is not. It is not tax advice — how a retirement year is going to land on your return is a question for your CPA, and the estimate you sign under penalty of perjury should come from that conversation. And it is not Social Security. The request is filed with Social Security, on its form, at its office or by mail; Utah SHIP counselors can also help you assemble it at no charge. What we do is put the tier table, your retirement date and your income estimate on one page so you know whether the form is worth filing before you fill it out.

How we know all this: the Medicare On Main Data Desk frames every article with public data. Every rule quoted here — the seven major life-changing events and the "or your spouse" language, the exclusion of sales, transfers and ordinary investment risk, the definition of a significant reduction as one that lowers or eliminates the adjustment, the request-year effective date and the following-year alternative, the calendar-year deadline and the March 31 extension for fourth-quarter events, the acceptable evidence for a work stoppage including a signed statement under penalty of perjury, the IRS-letter requirement for amended returns, the three sibling routes for a new initial determination, the reconsideration rule, and the conditions under which Social Security stops using the more recent year — was read directly from 20 CFR Part 418, Subpart B, sections 418.1201 through 418.1335, on the eCFR on the date of publication. The 2026 IRMAA thresholds, total Part B premiums, Part D adjustments and the roughly 8% share of Part B enrollees affected are from the CMS fact sheet of November 14, 2025. The $240.40-per-month and $5,769.60-per-year figures are our own arithmetic on that table for a couple moving from Tier 2 to the standard premium; they are not published by CMS. Form SSA-44 is linked but not quoted, because the form is a means of filing the request the regulation defines. No plan, carrier or organization is named, criticized or endorsed here.
