If a parent's Medicare premiums include an IRMAA surcharge based on old, higher income, they can ask Social Security to recalculate it after a life-changing event — such as retirement, the death of a spouse, or divorce — using Form SSA-44, per SSA. IRMAA is an income-related surcharge added to Part B and Part D premiums for higher earners, applied above $109,000 in income for an individual or $218,000 for a couple in 2026. A successful appeal can lower or remove it.

How Do I Appeal an IRMAA Determination for a Parent After a Life-Changing Event? (2026)
By Chuck Brodsky, Co-Founder, MediNav — Updated July 2026 — 6 min read
Quick answer
If a parent is paying more for Medicare because Social Security looked at a tax return from two years ago — before they retired or lost a spouse — that surcharge may not reflect their real, current income. The fix is a specific form and the right supporting document, and it is very much worth doing.
What IRMAA is and why it lags
IRMAA — the Income-Related Monthly Adjustment Amount — is an extra charge added to a parent's Part B and Part D premiums when income is above a threshold. In 2026 it begins above $109,000 in modified adjusted gross income for an individual and $218,000 for a couple; the standard Part B premium without IRMAA is $202.90. The catch is timing: Social Security sets IRMAA using the tax return from two years earlier, so a parent who has since retired can be charged on income they no longer have.
The life-changing events that qualify
Social Security will reconsider IRMAA after specific life-changing events: marriage, divorce or annulment, death of a spouse, you or your spouse stopping or reducing work, loss of income-producing property, or loss or reduction of certain pension income. Retirement — "work stoppage" — is the most common. The event must have reduced the income that IRMAA was based on.
How to appeal with Form SSA-44
File Form SSA-44, "Medicare Income-Related Monthly Adjustment Amount — Life-Changing Event," with Social Security. On it, you identify the event, the date, and your parent's expected lower income, and you attach proof — such as a signed statement of retirement, a death certificate, or a more recent tax return. Social Security uses the newer income to recalculate the surcharge, and can refund amounts already overpaid for the year.
When to appeal versus wait
If the drop in income is due to a qualifying life-changing event, appeal now with SSA-44 rather than waiting for the two-year lag to catch up. If instead the older return was simply wrong or has since been amended, that is a different correction, handled with the amended return. For the full premium picture, including the standard and surcharge tiers, see the IRMAA explainer.
What a caregiver should do
Check the Social Security IRMAA notice your parent received; it states the income year used and the surcharge. If a qualifying event has lowered their income since that year, gather the proof and file Form SSA-44 promptly. Acting early means fewer months of overpayment, and Social Security can adjust the current year once the appeal is approved.

Frequently asked questions
What if my parent retired and their income dropped?
Retirement is the most common qualifying life-changing event for an IRMAA appeal. File Form SSA-44, report the work stoppage and your parent's expected lower income, and attach proof. Social Security will recalculate the surcharge on the newer income rather than the two-year-old tax return, and can refund overpayments for the year.
What income triggers IRMAA in 2026?
The surcharge applies above $109,000 in modified adjusted gross income for an individual and $218,000 for a couple in 2026. Below those thresholds, a parent pays the standard Part B premium of $202.90 with no IRMAA. Above them, the surcharge rises in tiers on both Part B and Part D.
Which life events qualify for an appeal?
Marriage, divorce or annulment, death of a spouse, you or your spouse stopping or reducing work, loss of income-producing property, and loss or reduction of certain pension income. The event must have lowered the income IRMAA was based on. Retirement is the most frequent qualifying event.
What form do I use?
Form SSA-44, "Medicare Income-Related Monthly Adjustment Amount — Life-Changing Event." You describe the event and date, estimate your parent's reduced income, and attach supporting documents. Submit it to Social Security. Using the correct form with proof is what lets them recalculate the surcharge before the two-year lag would.
What proof does Social Security want?
Documents that show the event and the lower income — for example, a signed statement or letter confirming retirement, a death certificate for a deceased spouse, divorce papers, or a more recent tax return. The stronger the proof of both the event and the new income, the smoother the recalculation.
Can my parent get a refund?
Yes. If the appeal is approved, Social Security recalculates the surcharge for the year and can refund IRMAA amounts already overpaid. Filing promptly after the qualifying event limits how many months are overcharged in the first place, so do not wait for the two-year income lag to correct itself.
