Medicare’s income-related monthly adjustment amount, known as IRMAA, is based on your tax return from two years ago, so a job loss, retirement, divorce, or death in the family can leave you paying a surcharge that no longer reflects what you earn. Social Security recognizes eight IRMAA life-changing events that let you ask for a new determination using a more recent year’s income: death of a spouse, marriage, divorce or annulment, work stoppage, work reduction, loss of income-producing property, loss or reduction of pension income, and an employer settlement payment. If your situation fits one of these, you file Form SSA-44 with documentation and Social Security recalculates your Part B and Part D surcharges.1
The Eight Events That Qualify
The list in the federal regulations is closed. If your income dropped for a reason that isn’t on it, Social Security cannot grant a new determination no matter how large the drop was.
- Death of a spouse. Losing a spouse usually cuts household income and changes your filing status.
- Marriage. A new marriage changes both filing status and the combined income measured against the joint brackets.
- Divorce or annulment. When a marriage legally ends, your income is measured on its own against the individual brackets.
- Work stoppage. Retiring or otherwise stopping all employment counts, whether you chose to stop or your employer ended the job.
- Work reduction. A significant cut in hours or a move to a lower-paying position qualifies under the same regulatory provision as a full stoppage.
- Loss of income-producing property. Property that was actively generating income for you, lost through an involuntary event (see below).
- Loss of or reduction in pension income. A pension plan that is terminated, restructured, or significantly reduced.
- Employer settlement payment. A lump-sum payout from a current or former employer tied to the company’s closure, bankruptcy, or reorganization, which can inflate one year’s income and push you into a higher bracket.
These events can apply to you or to your spouse. Your spouse’s retirement or job loss can support your request even if your own work situation hasn’t changed.
What “Income-Producing Property” Really Means
This category is narrower than most people assume. The property has to have been generating income, and the loss has to be involuntary. Social Security’s guidance points to farmland, rental homes, crops, livestock, business vehicles like tractor-trailers or limousines, and even show dogs. A coin collection or a personal-use vacation home doesn’t qualify because it doesn’t produce income. Donating, gifting, or selling at a loss don’t qualify either, because they’re voluntary.
Qualifying involuntary causes include floods, hurricanes, tornadoes, fires, earthquakes, volcanic eruptions, crop or livestock disease, arson, government seizure through eminent domain, and theft such as burglary, embezzlement, extortion, or investment fraud.
What Doesn’t Qualify
Several common income spikes and drops fall outside the list, and this is where beneficiaries most often get turned down.
Selling investments or a home at a gain. Capital gains that push you into a higher bracket are treated as voluntary transactions, even when you sold because you had to. The same applies to home sales.
Ordinary investment losses. Losses on stocks, bonds, or mutual funds are excluded as “the ordinary risk of investment.” Lost dividend income doesn’t qualify either, unless it resulted from criminal theft such as fraud or embezzlement.
Roth conversions and voluntary retirement withdrawals. A Roth IRA conversion that spikes your taxable income is voluntary, so it isn’t a life-changing event. Large IRA or 401(k) distributions you chose to take are treated the same way, even if they push you above an IRMAA threshold for a year or two.
Will Your Income Drop Enough to Matter?
IRMAA is set in tiers, so the request only helps if your new income crosses into a lower bracket. Dropping from $160,000 to $145,000 on an individual return keeps you in the same tier and changes nothing. Dropping from $160,000 to $140,000 moves you down one tier and saves you $121.70 per month on Part B alone.
There is no minimum drop required to file. The practical test is whether your estimated modified adjusted gross income for the newer year falls below the next bracket line. MAGI for IRMAA is your adjusted gross income (Form 1040, line 11) plus tax-exempt interest (line 2a). Compare that figure to the 2026 brackets before you file; if you’d still land in the same tier, the paperwork won’t change your premium.
Filing Form SSA-44
Form SSA-44 is the only form Social Security uses for this. On it you identify the event, give the date it happened, name the tax year you want Social Security to use instead, and estimate your MAGI for that year. You can point to a year that has already ended (using the actual return) or to the current or coming year (using an estimate). The event date must fall in the same year as, or earlier than, the tax year you’re asking Social Security to use.
Documentation depends on the event:
- Death of a spouse: certified death certificate, public record of death, or coroner’s certificate.
- Divorce or annulment: certified copy of the divorce decree or annulment order.
- Work stoppage or reduction: a signed letter from the employer, pay stubs, or documents showing transfer of your business. If none of those exist, your own signed statement on the form, under penalty of perjury, is accepted.
- Loss of income-producing property: an insurance adjuster’s statement of loss or a letter from a state or federal agency documenting the uncompensated loss.
- Loss of pension income: documentation from the plan administrator showing termination or reduction.
- Employer settlement: documentation tying the settlement to the employer’s closure, bankruptcy, or reorganization.
There is no deadline for filing after the event. You can also file before your income actually drops: Social Security’s instructions say you may report “an income reduction that has already occurred or an income reduction that you anticipate occurring this or next year.” You can submit the form through your my Social Security account, by fax to your local field office, or by mail. Keep copies of everything.
When the Lower Premium Kicks In
In the typical case, an approved reduction is effective January 1 of the year you file. If you enrolled in Part B partway through that year, the effective date is the first day of your enrollment. When the event happened the year before and you file early in the following year, Social Security can sometimes apply the adjustment back to the prior year. If your income won’t drop until next year, the change takes effect January 1 of that year.
When Social Security rules in your favor, it refunds the excess IRMAA you paid between the effective date and the date of decision. Filing sooner limits how many months of overpayment stack up before the correction posts.
Social Security later verifies your reported income against your actual tax return. If the numbers don’t match your estimate, your premiums will be adjusted again, which can mean additional refunds or retroactive charges. If your estimate changes during the year, or you amend your return, contact Social Security promptly.
If Social Security Denies Your Request
You have 60 days from receipt of the decision notice to ask for reconsideration. Social Security presumes you received the notice five days after the date printed on it, so the clock starts from that presumed date unless you can show the notice arrived later.
Reconsideration is handled by a different employee, who reviews the case from scratch. Most disputes are resolved at this step, especially when the original denial came from missing paperwork rather than a real disagreement about whether the event qualifies. You can submit additional documentation with your reconsideration; you don’t have to start the request over. If reconsideration doesn’t resolve it, the next steps are a hearing before an Administrative Law Judge at the Office of Medicare Hearings and Appeals, then review by the Medicare Appeals Council, and finally a civil action in federal district court.
