How to Appeal IRMAA With Form SSA-44: Life-Changing Events That Qualify

You retired last year. Your income is a fraction of what it was. And now Medicare is charging you IRMAA surcharges based on your old salary, because IRMAA looks at a two-year-old tax return. This is the single most common unfair-feeling IRMAA notice, and it is also one of the most fixable. Appealing IRMAA with Form SSA-44 lets Social Security throw out the old return and use your current, lower income instead, if your income dropped because of a qualifying life-changing event. Here is the full process.

Why the appeal exists

For 2026, IRMAA is based on your 2024 MAGI: above $109,000 single or $218,000 joint, and surcharges kick in. The two-year lookback is mechanical. It cannot tell the difference between someone still earning $180,000 and someone who retired in 2025 and now lives on $70,000. Congress built the SSA-44 escape hatch precisely for that gap. When a defined life-changing event caused your income to fall, you can ask Social Security to set the stale tax return aside and recalculate on current income.

The key insight: the appeal does not dispute the old return. It says the old return no longer describes you. That framing matters, because the appeal lives or dies on the event, not the math.

The 8 qualifying life-changing events

Only these count. A genuine income drop that does not fit one of them does not qualify, no matter how real it feels.

  1. Marriage. Your combined income picture changed; also note that your filing status and thresholds change with it.
  2. Divorce or annulment. Dropping from the joint threshold to the single threshold can move your IRMAA even when your own earnings did not change.
  3. Death of a spouse. The surviving-spouse trap: single-filer thresholds are roughly half the joint ones, so IRMAA can worsen even as income falls. The appeal can help.
  4. Work stoppage. You or your spouse stopped working. Retirement is the classic case.
  5. Work reduction. You or your spouse cut back hours or took lower pay.
  6. Loss of income-producing property through no fault of your own, such as a disaster or theft. A voluntary sale does not count.
  7. Loss of pension income. A reduction or termination of a defined benefit pension.
  8. Employer settlement payment following the employer's closure, bankruptcy, or reorganization.

What does not qualify: voluntary high-income events. A big Roth conversion, a property sale you chose to make, or simply having a high-income year fall out of the lookback are not life-changing events. Those surcharges last one year and recalculate down on their own. I cover the Roth conversion side in How Retirees Actually Lower MAGI to Avoid IRMAA.

How to file Form SSA-44

  1. Download the form. Form SSA-44, "Medicare Income-Related Monthly Adjustment Amount, Life-Changing Event," is on SSA.gov, or pick one up at a local Social Security office.
  2. Pick your event and its date. Check one of the eight and enter when it happened. Work stoppage means the date you stopped working, not your official retirement party.
  3. Estimate your reduced MAGI. Enter your estimated modified adjusted gross income for the current year, and for next year too if it will be lower still. Be realistic; Social Security will verify.
  4. Attach documentation, this is where appeals stall. You need evidence of both the event and the income drop: a letter from your employer confirming retirement or reduced hours, a marriage or death certificate, pension statements showing the loss, plus proof of current income such as pay stubs, pension statements, or a recent tax return reflecting the change.
  5. Submit it. Mail it, bring it to a Social Security office in person (booking ahead is wise), or in some cases handle it by phone at 1-800-772-1213. Keep copies of everything.
  6. Follow up. Processing can take several weeks to a few months. If approved, your premiums adjust for the current year, and any surcharges you already paid come back as a retroactive refund.

Act promptly. If you just received an IRMAA notice based on a working year and you retired in the meantime, file now rather than paying a year of surcharges you may not owe. The refund only comes back if you file.

Where do you stand against the 2026 thresholds?

Before you file, confirm which tier the lookback return put you in and how far your current income sits below it. The calculator shows your tier, your cliff distance, and the 2026 premium for both.

Frequently Asked Questions

What is Form SSA-44?

Form SSA-44, titled "Medicare Income-Related Monthly Adjustment Amount, Life-Changing Event," is how you ask Social Security to recalculate your IRMAA using current-year income instead of the two-year-old tax return, when a qualifying life-changing event reduced your income.

Does retirement count as a life-changing event for IRMAA?

Yes. "Work stoppage," which includes retirement, is one of the qualifying life-changing events. A new retiree being charged IRMAA based on a final high-earning working year is one of the most common successful appeal scenarios.

Can I appeal IRMAA because of a one-time income spike like a Roth conversion?

No. A voluntary high-income event like a Roth conversion or an asset sale is not a qualifying life-changing event, so SSA-44 will not help. IRMAA from a one-time spike lasts one year and recalculates down automatically the next year.

How long does an IRMAA appeal take, and do I get a refund?

Processing typically takes several weeks to a few months. If your appeal is approved after you already paid surcharges, Social Security refunds the excess retroactively.
