IRMAA Life-Changing Event: How to Lower Your Medicare Premium With Form SSA-44
Two years. That's how far back Medicare looks at your income to decide whether you pay IRMAA, the income-related surcharge on Part B and Part D. Your 2026 premiums are generally based on the tax return you filed in 2025 for tax year 2024. So the year you retire, Social Security can bill you as if you still had a full salary.
There's a fix, and it isn't an appeal. If one of eight specific "life-changing events" cut your income, you can ask Social Security to use a more recent year instead. The form is SSA-44. The list of events is short and strict, and the paperwork has to be right. Here's how it works, what counts, what doesn't, and what to send.

How IRMAA picks your income year
Social Security, not Medicare, makes the IRMAA decision. It uses data the IRS sends it electronically: your modified adjusted gross income (MAGI) and your tax filing status. SSA defines MAGI as your adjusted gross income plus tax-exempt interest income. On Form SSA-44, that's line 11 of IRS Form 1040 plus line 2a. The federal rule, 20 CFR 418.1010, also adds a few rarer items, like foreign earned income.
For 2026 premiums, SSA says the information is generally from a tax return filed in 2025 for tax year 2024. Sometimes the IRS only has the older return (tax year 2023). By the same two-year rule, 2027 IRMAA will generally be based on your 2025 tax return, the one most people filed this spring.
That lag is the whole problem. Plenty of people turn 65, work one more year, retire, and then get an IRMAA notice based on the salary they no longer earn. The life-changing event process exists for exactly that.
Two things the process can't do. It can't add IRMAA: if the IRS data shows you don't owe it, SSA won't impose it based on what you report. And it only works when your income dropped enough to matter. Under 20 CFR 418.1215, a reduction is "significant" only if it moves you to a lower IRMAA tier or below the threshold entirely. Dropping from $160,000 to $150,000 as a single filer doesn't change your tier, so it doesn't qualify.
The 2026 IRMAA brackets
These are the official 2026 figures from CMS. Each Part B total is the $202.90 standard premium plus the income-related amount. Part D works differently: the add-on is paid on top of whatever your drug coverage premium is, and it goes to Medicare, not to the plan.
| Single MAGI | Joint MAGI | IRMAA | Total Part B |
|---|---|---|---|
| $109,000 or less | $218,000 or less | $0.00 | $202.90 |
| Over $109,000 to $137,000 | Over $218,000 to $274,000 | $81.20 | $284.10 |
| Over $137,000 to $171,000 | Over $274,000 to $342,000 | $202.90 | $405.80 |
| Over $171,000 to $205,000 | Over $342,000 to $410,000 | $324.60 | $527.50 |
| Over $205,000 to under $500,000 | Over $410,000 to under $750,000 | $446.30 | $649.20 |
| $500,000 or more | $750,000 or more | $487.00 | $689.90 |

| Single MAGI | Joint MAGI | Part D IRMAA |
|---|---|---|
| $109,000 or less | $218,000 or less | $0.00 |
| Over $109,000 to $137,000 | Over $218,000 to $274,000 | $14.50 |

Married and filing separately while living with your spouse at any point in the year? The brackets are much harsher: above $109,000 you jump straight to $649.20 on Part B ($446.30 IRMAA) and $83.30 on Part D, and at $391,000 or more it's $689.90 and $91.00.
CMS says Part B IRMAA affects roughly 8% of people with Part B, and about 8% of people with Part D pay the Part D add-on. CMS hasn't published the 2027 brackets yet. They come with the 2027 Part B premium announcement, which the last three years arrived between mid-October and mid-November. I covered the timing in what we know about the 2027 Part B premium.
The eight life-changing events
The federal rule (20 CFR 418.1205) and SSA's staff manual (POMS HI 01120.005) list them. SSA's manual is blunt: "Our list of LCEs for IRMAA purposes is exclusive." If your situation isn't on it, the SSA-44 route is closed.
| Event | What it covers | Fine print |
|---|---|---|
| Death of spouse | Your spouse dies | Often changes your filing status as well as your income |
| Marriage | You marry | Joint brackets are twice the single ones |
| Divorce or annulment | Your marriage ends | Applies only to the person who reports it |
| Work stoppage | You or your spouse stop working: retirement, layoff, sale of a business | Can be reported before or after the last day of work |
| Work reduction | You or your spouse cut hours: partial retirement, full-time to part-time | Has its own checkbox; same evidence rules as work stoppage |
| Loss of income-producing property | Rental homes, farmland, crops, livestock, business vehicles lost to causes beyond your control | Natural disaster, disease, arson, eminent domain, criminal theft or fraud |
| Loss of pension income | A traditional defined benefit or cash balance pension ends or is cut | Plan failure or termination, or a scheduled end you chose earlier |
| Employer settlement payment | A settlement from a current or former employer | Only if caused by the employer's closure, bankruptcy or reorganization |

A few details that trip people up.
The event can be old. SSA's manual says the event may have happened at any time in the past. What matters is that it happened before the income drop, and that the drop shows up in a more recent tax year than the one SSA used.
It's one spouse at a time. If you and your spouse both pay IRMAA and you both retired, each of you has to report. SSA doesn't extend one spouse's request to the other.
The property rule is narrow, and it matters in Florida. A rental home destroyed in a hurricane can qualify; the federal rule specifically mentions real property in a Presidentially or Gubernatorially declared disaster area. A condo you use yourself doesn't count, because it doesn't produce income. Selling a rental doesn't count either, because you chose to sell.
Pension loss has two paths. Either the plan failed or was terminated (for example, through a bankruptcy restructuring), or the payments stopped on a schedule you picked years ago, like a 20-year annuity instead of a lifetime pension.
What doesn't count
This is where most disappointments come from. A one-time spike in income two years ago is a common reason people get an IRMAA notice they didn't expect, and SSA's manual specifically calls those "non-qualifying events." Its examples:
- capital gains from the sale of property (including selling a house at a big gain)
- converting a traditional IRA to a Roth
- cashing in bonds
- lottery or casino winnings
The manual also lists drops in income that aren't life-changing events: an ordinary loss of dividend income, losing child support or alimony, and the voluntary sale of income-producing property. Events that raise your expenses but not your income, such as higher medical bills or a higher cost of living, don't count either (20 CFR 418.1210).
If your notice is based on a one-time gain, the honest answer is usually that IRMAA lasts for the premium year tied to that tax return and then resets when the next year's lower return comes in. You can still file an appeal if you believe SSA got it wrong, and SSA will take it if you insist. But an appeal doesn't turn a capital gain into a life-changing event.
Planning point: if you expect a large one-time gain (a home sale, a Roth conversion), it can help to know which future premium year it will land on. Talk to a tax professional before you trigger it; I'm not giving tax advice here.
Documents Social Security wants
You need two kinds of proof: proof of the event, and proof of your newer, lower income. SSA must see original documents or certified copies of the event evidence. You can attach them to the form and SSA mails them back, or show them to an SSA employee in person. Photocopies of a death certificate won't do.
| Event | Evidence listed on Form SSA-44 |
|---|---|
| Marriage | original marriage certificate or certified copy of the public record |
| Divorce or annulment | certified copy of the decree |
| Death of spouse | certified copy of death certificate, public record of death, or coroner's certificate |
| Work stoppage or reduction | original signed employer statement, copies of pay stubs, or original/certified business transfer documents; otherwise a signed statement under penalty of perjury on the form |
| Loss of income-producing property | original insurance adjuster's statement of loss or a letter from a state or federal government about the uncompensated loss; investment fraud/theft also needs proof of conviction |
| Loss of pension income | letter or statement from the pension fund administrator |
| Employer settlement payment | letter from the employer stating the settlement terms of the bankruptcy court and how it affects you or your spouse; SSA's manual also accepts a court document or a statement from the employer's attorney showing the settlement and its terms |
| Your newer income (all events) | Signed copy of your tax return or an IRS transcript; if you give an estimate, a signed copy of the return once you file it |
Source: SSA, Form SSA-44 (12-2025); SSA POMS HI 01120.030, HI 01120.035 and HI 01120.043.
No return filed yet for the year your income dropped? That's normal; you'll be estimating. The form asks for your estimated adjusted gross income, tax-exempt interest and filing status for the more recent year. Step 3 lets you give a second estimate for the following year if you expect income to drop even further. If you leave that blank, SSA uses the first estimate for the next year too.
An estimate is a sworn number, not a guess you can forget about. You sign under penalty of perjury, you send the real return once it's filed, and if your income turns out higher, SSA can make corrections later, including retroactive charges. If your estimate changes, tell SSA; 20 CFR 418.1240 says it takes updated figures until the end of the calendar year after the tax year it used.
For retirement, a letter from your employer with your last day of work is the cleanest proof. If you can't get one, the form lets you sign a statement under penalty of perjury about the work stoppage.
Example: retiring at 66 in Naples
Hypothetical, using official 2026 figures. Say Linda lives in Naples, files as single, and has Part B and Part D all year. Her 2024 MAGI was $160,000. She retired in March 2026 and expects her 2026 MAGI to be about $80,000, mostly Social Security and IRA withdrawals.
| Based on 2024 return (notice) | Based on 2026 estimate (SSA-44) | |
|---|---|---|
| MAGI used | $160,000 | $80,000 |
| 2026 tier (single) | Over $137,000 up to $171,000 | $109,000 or less |
| Part B premium, monthly | $405.80 | $202.90 |
| Part D IRMAA, monthly | $37.50 | $0.00 |
| IRMAA total, monthly | $240.40 | $0.00 |
| IRMAA total, 12 months | $2,884.80 | $0.00 |
Source: hypothetical example; amounts from CMS, 2026 Medicare Parts A & B Premiums and Deductibles fact sheet (Nov. 14, 2025); rules from 20 CFR 418.1230 and SSA POMS HI 01120.005. Maru Insurance calculation.
She files Form SSA-44, checks "Work Stoppage," attaches her employer's retirement letter, and enters the 2026 estimate. Because her Part B was in effect all year and the event happened in 2026, the new determination is generally effective January 2026, so her 2026 IRMAA drops to zero for the whole year. That removes the $202.90 Part B add-on and the $37.50 Part D add-on: $240.40 a month, or $2,884.80 over 12 months. She still pays the $202.90 standard Part B premium and her drug coverage premium.
The part people miss: 2027. Her 2025 MAGI was $150,000 because she worked all year. Since 2027 IRMAA generally uses the 2025 return, SSA's IRS data would put her right back in an IRMAA tier (at 2026 brackets, the same one). SSA's manual tells staff to make the determination for the next premium year too, using her second-year estimate or, if she left that blank, her 2026 estimate. So one well-documented SSA-44 should cover both years. When she files her 2026 return next spring, she sends SSA a signed copy.
Linda's numbers are made up. Run your own against the tables above, and keep in mind the 2027 brackets aren't out yet.
How and when to file
Social Security lists these ways to ask for a lower IRMAA after a life-changing event on its Request to lower IRMAA page:
- Online: sign in to (or create) your Social Security account and submit the SSA-44 online. SSA still has to see original or certified evidence of the event, so ask how it wants those.
- Mail or fax: send Form SSA-44 with your evidence to your local Social Security office.
- Appointment: schedule one online or by phone and bring the originals.
- Phone: call 1-800-772-1213 (TTY 1-800-325-0778), Monday through Friday, 8 a.m. to 7 p.m., and say you want to lower your IRMAA because of a life-changing event.
The form itself is optional; SSA's manual says you can make the request verbally or in writing. I'd still use it. It forces you to put the event, the date and both income estimates in one place,. Mailing originals is a risk; if you'd rather not, bring them to an appointment.
Timing. You can file any time after the event and the income drop. Under 20 CFR 418.1230, the new determination is generally effective January 1 of the year you make the request (or your first month of Part B, if later). If your income won't drop until next year, it takes effect January 1 of next year. One exception helps people who retire late in the year: if the event happened between October 1 and December 31 and you ask by March 31 of the following year, SSA can apply it back to January of the year the event happened.
The practical rule: when the IRMAA notice for next year arrives and your income has already dropped, don't sit on it. And if you retire in, say, November, don't wait past March 31 to file.
Life-changing event, appeal or IRS correction?
These get mixed up constantly, and picking the wrong one wastes months.
| Your situation | What to do | Form / proof |
|---|---|---|
| Income dropped because of one of the eight events | Ask for a new initial determination (no appeal needed) | SSA-44 plus event proof and income proof |
| The IRS figure SSA used is wrong | Contact the IRS first (1-800-829-1040) to get it corrected | IRS documentation of the correction |
| You amended the tax return SSA used | Ask SSA to use the amended return | Amended return plus IRS receipt letter or transcript |
| SSA used a 3-year-old return and you've filed a newer one | Ask SSA to use the 2-year-old return | Signed return or IRS transcript |
| You think SSA applied the rules wrong | Request reconsideration within 60 days | Appeal online or Form SSA-561-U2 |
Source: SSA POMS HI 01120.001, HI 01120.045, HI 01140.001; SSA, Premiums: Rules for Higher-Income Beneficiaries.
The reconsideration deadline is 60 days from when you receive the IRMAA notice, and SSA assumes you got it 5 days after the date printed on it. Late requests need good cause. Above reconsideration there are three more levels: a hearing before an HHS administrative law judge, the Medicare Appeals Council, and federal court.
You can file an appeal and a life-changing event request at the same time, within the appeal period. For an amended return, SSA's manual says the request has to come within 3 calendar years after the close of the tax year you amended, and SSA will use the amended figures even if they raise your IRMAA.
One more case: if you're married filing separately but didn't live with your spouse at any time during the year, don't use SSA-44. The form says to call SSA instead. Questions about how the amended return or filing status choice affects your taxes belong with your tax preparer.
What I'd do
- Read the notice for the tax year it used. If it's two years back and your income has since fallen because of one of the eight events, you're in SSA-44 territory.
- Check the tier math. Use the tables above. If your newer MAGI is still in the same tier, the request won't change anything.
- Order the originals now. Certified death certificates, divorce decrees and employer letters can take time to get.
- Estimate honestly and keep your worksheet. Include IRA withdrawals, pensions, taxable Social Security and tax-exempt interest. A tax professional can check the number.
- Give the second-year estimate if next year's income will be lower still.
- File online, by mail or at an appointment, and keep copies of everything you send.
- Send the filed return when it's done, and tell SSA if your estimate changes.
IRMAA doesn't change which coverage you can have; it changes what you pay for Part B and for Part D. If you're reviewing drug coverage for 2027 during Open Enrollment, see Medicare Part D in 2027 and Medicare Part D in Florida. If you're still working past 65 and timing Part B around a retirement date, Medicare and employer coverage covers the enrollment side, and Medicare in Florida explains how the pieces fit together here.
IRMAA rules come from federal law and SSA regulations, and your own notices and tax records control your situation. Confirm the details with Social Security, SHINE or a licensed agent, check the tax side with a tax professional, and talk to an attorney for legal questions.
