IRMAA Appeals: How to Lower Medicare Premiums After a Life-Changing Event

Medicare Part B and Part D premiums are income-based. If your income was high two years ago, you’re paying an IRMAA surcharge today — potentially hundreds of dollars per month more than the standard premium. But income can change dramatically: you retire, a spouse dies, you divorce, you lose a business.

When income drops significantly due to a qualifying life-changing event, you can appeal your IRMAA determination and request a reduction based on your more recent (lower) income. The Social Security Administration calls this using a “more recent tax year.”

This guide explains exactly how the appeal process works, which events qualify, and how to file.

How IRMAA Is Calculated

Social Security determines your IRMAA surcharge using your modified adjusted gross income (MAGI) from your tax return two years prior. In 2025, your premiums are based on your 2023 tax return. This two-year lag creates the appeal situation: your 2023 income might have been high, but something happened since then that dramatically reduced your current income.

For a complete breakdown of the IRMAA brackets and what each tier costs, see IRMAA Medicare surcharges.

Qualifying Life-Changing Events

Social Security recognizes eight categories of life-changing events that may warrant using a more recent tax year to determine IRMAA:

1. Marriage

If you married during the tax year in question or since then, your filing status changed, which can affect MAGI calculations. Marriage alone rarely reduces IRMAA (combined income often stays high), but it can matter in specific situations.

2. Divorce or Annulment

This is one of the more impactful qualifying events. When a couple divorces, each spouse’s individual income may be significantly lower than the joint MAGI used to calculate the IRMAA surcharge. If you divorced after the tax year used to determine your IRMAA, you can request that Social Security use a more recent tax year reflecting your individual post-divorce income.

Example: Your 2023 joint MAGI as a married couple was $280,000, placing you in a high IRMAA bracket. You divorced in 2024. Your 2024 individual MAGI was $115,000. You can request that Social Security use 2024 income instead, potentially dropping you to a lower IRMAA bracket or eliminating the surcharge entirely.

3. Death of a Spouse

When a spouse dies, the surviving spouse may shift from married filing jointly to single filing status. This is significant because the IRMAA thresholds for single filers are lower than for joint filers — meaning the same income that was under the threshold for a married couple may now trigger an IRMAA surcharge. But it also works in reverse: if the deceased spouse was the higher earner, the survivor’s individual income may be well below the IRMAA threshold.

You can request that Social Security use the year of or after the spouse’s death, reflecting your income as a single filer.

4. Work Stoppage

This is the most common qualifying event. If you or your spouse stopped working — retired, became unemployed, reduced work hours significantly — your current income is likely far lower than the income used to set your premiums.

“Work stoppage” includes:

• Full retirement
• Voluntary early retirement
• Job loss (layoff, position elimination)
• Significant reduction in hours or salary (typically at least a partial-year change that materially reduced annual income)

Example: You retired in late 2024. Your 2023 income was $210,000 from full-time employment. Your 2024 income with pension and Social Security was $72,000. You can appeal using 2024 income.

5. Work Reduction

Even if you didn’t stop working entirely, a significant reduction in work hours or income — such as going from full-time to part-time employment, or losing significant self-employment income — can qualify. The reduction must be significant enough to move you to a materially lower income level.

6. Loss of Income-Producing Property

If you had a significant loss of income from property you previously owned — your rental properties were damaged and uninhabitable, for example, or you sold income-producing real estate — this can qualify if it meaningfully reduced your income.

7. Loss of Pension Income

If you lost access to a pension — because your former employer’s pension plan was terminated, reduced, or eliminated — you may qualify to use a more recent tax year. Note: this refers to the actual loss of pension income, not simply stopping contributions to a pension or 401(k).

8. Receipt of Employer Settlement Payment

If you received an employer settlement payment — such as a severance payment or settlement from a wrongful termination lawsuit — that inflated your income in the base year, you can request that Social Security use a more recent year that doesn’t include this one-time payment.

What Does NOT Qualify

Many income drops do not qualify for an IRMAA appeal:

• Investment losses or market declines: Your portfolio declining in value is not a qualifying life-changing event
• Voluntary liquidation of assets: Selling a second home or drawing down savings that inflated income in the base year
• Roth conversions: If a Roth conversion in the base year pushed your income high, that is not a qualifying event (though this is an argument for managing conversions carefully — see retirement tax planning)
• Inheritance received: A large inheritance or one-time payout that boosted base-year income
• Discretionary income changes: Choosing to take larger retirement account distributions

If your income spike was temporary and due to a one-time non-recurring event that doesn’t fit the eight categories, you may not be able to appeal. Consult your Social Security office for your specific situation.

How to File an IRMAA Appeal: Form SSA-44

To request a reduction, you file Form SSA-44 (Medicare Income-Related Monthly Adjustment Amount — Life-Changing Event). This form is available on the Social Security Administration website (ssa.gov) or at any Social Security office.

What SSA-44 asks:

1. Your name, date of birth, Medicare Beneficiary Identifier (MBI), and contact information
2. Which life-changing event applies (you check a box for the category)
3. The date of the life-changing event
4. A description of the event
5. The tax year you want Social Security to use instead of the base year
6. Your estimated income for that more recent year (or your actual income if you’ve already filed)

Documentation you may need to attach:

• Work stoppage/reduction: Employer letter confirming retirement date or reduced hours, or final pay stub
• Divorce: Copy of divorce decree or separation agreement
• Death of spouse: Death certificate; may also need evidence of change in income
• Loss of pension: Documentation from pension administrator of plan termination or reduction
• Employer settlement: Settlement agreement or documentation of payment

Social Security does not require you to attach documentation in all cases — but having it ready speeds processing and avoids follow-up requests.

Where to Submit

You can submit SSA-44 by:

• Mail: To your local Social Security office (find it at ssa.gov/locator)
• In person: Walk into any Social Security office
• Fax: Some offices accept faxed forms — call your local office to confirm

You cannot submit SSA-44 online. Social Security’s online appeal process (mySSA portal) does not currently support IRMAA life-changing event requests.

Allow 4–8 weeks for processing. If approved, the reduction applies prospectively — you won’t receive refunds for premiums already paid in prior months, but your premiums going forward will reflect the new determination.

Using Estimated vs. Actual Income

When you file SSA-44, you can use either:

• Estimated income for the current year or the prior year (if you haven’t filed taxes yet): You provide Social Security with your best estimate. If your actual income differs materially when you file, Social Security will reconcile.
• Actual income from the prior year (if you’ve filed your taxes): The more precise approach. Social Security will verify against IRS records.

Using a prior year’s actual income is more reliable and results in a definitive determination. If you’re appealing mid-year based on an event that happened this year, you may need to use an estimate.

What Happens If Estimated Income Is Wrong

If you estimated your income and the actual amount turns out higher than you estimated, Social Security will adjust your premiums after the fact — either increasing future premiums or billing you for the difference. If the actual income was lower than estimated, you’ll get credit for the overage going forward.

Don’t deliberately underestimate. The reconciliation process will catch it, and there’s no benefit to inaccurate estimates.

Interaction with Roth Conversions

One important planning consideration: if you’re doing Roth IRA conversions to manage future RMDs and tax brackets, those conversions increase your MAGI and can trigger or increase IRMAA surcharges (see IRMAA Medicare surcharges for the bracket thresholds).

Roth conversions are not a qualifying life-changing event — you can’t appeal an IRMAA surcharge caused by your own Roth conversion strategy. This is a reason to model IRMAA carefully when sizing conversion amounts, particularly in years right before Medicare enrollment.

See retirement tax planning for more on Roth conversion strategy in the context of Medicare costs.

Filing Deadlines

There is no strict deadline to file SSA-44 — you can request a reduction at any time. However, the reduction only applies prospectively from the date Social Security processes your request. The longer you wait after a qualifying event, the more months of higher premiums you’ve already paid without recovery.

File as soon as possible after the qualifying event.

If Social Security denies your appeal and you disagree, you can request a formal hearing before an Administrative Law Judge (ALJ) through the standard Medicare appeals process.

Tracking IRMAA Year to Year

IRMAA is recalculated each year. Each fall, Social Security sends determination notices for the following year based on the latest tax returns on file with the IRS.

• If your income drops back below IRMAA thresholds on its own (your 2-years-back income is naturally lower), your surcharge will be reduced or eliminated without any appeal
• If your income remains high because of an ongoing event, you may need to refile SSA-44 each year if the underlying qualifying event is still ongoing (e.g., ongoing reduced work)
• If you’ve had a major life event but your income in the 2-year-back tax return was still high, file SSA-44 using a more recent year with lower income

Practical Examples

Example 1: Retirement

Situation: You retired January 1, 2025. Your 2023 MAGI (full-time salary) was $185,000, putting you in the second IRMAA tier (+$594.60/month combined Part B and D in 2025). Your 2024 income (partial year working, partial year retired) was $140,000.

Action: File SSA-44 using 2024 as the more recent year ($140,000 MAGI). Your new bracket falls into the first IRMAA tier. Savings: $200+/month in reduced surcharges.

Better action: If you’ve already filed your 2024 return and 2024 income reflects mostly retirement income (pension + partial Social Security), you may be able to use 2025 estimated income if it’s below the threshold entirely, eliminating IRMAA.

Example 2: Death of Spouse

Situation: Your spouse died in 2024. Your 2023 joint MAGI was $210,000. Your 2024 individual MAGI (your income only, after spouse’s death) was $78,000.

Action: File SSA-44 listing death of spouse as the life-changing event, using 2024 as the more recent year. At $78,000 as a single filer, you are below the IRMAA threshold and should owe no surcharge. Attach the death certificate.

Example 3: Part-Time Transition

Situation: You reduced from full-time to part-time in June 2024. Your 2023 MAGI was $165,000. Your estimated 2024 MAGI is $105,000 (including partial full-time and partial part-time income).

Action: File SSA-44 under “work reduction,” providing documentation of the reduction in work hours (letter from employer) and an estimated 2024 income of $105,000. At $105,000 individual income, you remain in the first IRMAA tier — but the savings vs. not appealing can be $100+/month.

Summary

The IRMAA appeal process is straightforward — the challenge is knowing it exists. Thousands of Medicare beneficiaries pay hundreds of dollars per month in unnecessary surcharges after their income drops, simply because they don’t know they can appeal. Filing SSA-44 is free, takes less than an hour, and can produce meaningful premium savings for years.
