Medicare's Income-Related Monthly Adjustment Amount, known as IRMAA, adds a surcharge on top of the standard 2026 Part B premium of $202.90 per month and also increases Part D premiums. The Social Security Administration bases that surcharge on your Modified Adjusted Gross Income (MAGI) from two years prior, so your 2026 IRMAA is calculated from your 2024 tax return. That two-year lag creates a common and correctable problem: a retiree who stopped working in 2025, a surviving spouse who lost a partner's pension income, or a person whose household shrank after a divorce may be paying 2024-peak-income surcharges that no longer reflect reality. Federal law specifically created Form SSA-44 for exactly this scenario. Filing the form is not a formal appeal, it is a request for a new initial determination using a more recent income figure that better reflects your life-changing event.
The 2026 IRMAA brackets have five tiers above the standard premium, with surcharges ranging from $81.20 per month (Tier 1, for single filers with 2024 MAGI between $109,000 and $137,000) to $487.00 per month (Tier 5, for single filers with 2024 MAGI above $500,000). Each tier also carries an additional Part D surcharge of $14.50 to $91.00 per month. A married couple where both spouses are on Medicare and land in Tier 3 could be paying over $649 per month in combined IRMAA surcharges on Part B alone. Retirement, divorce, and spouse death are among the eight qualifying life-changing events that allow you to request a downward recalculation using a more recent, lower income year. This guide walks through each qualifying event, the documentation required, and the exact steps to file Form SSA-44 in 2026.
7 Steps to Get Coverage
Common Mistakes That Cost People Thousands
The most common errors that get SSA-44 requests denied or delayed in 2026:
- Citing a non-qualifying income reduction. Roth IRA conversions, large IRA withdrawals, home sale capital gains, and inheritances do not count as qualifying life-changing events under SSA rules, even if they caused your 2024 MAGI to spike. SSA will deny the request immediately.
- Submitting an incomplete Form SSA-44. Leaving the MAGI estimate blank, omitting the event year, or failing to sign the attestation are the most common processing delays. SSA mails a deficiency notice that restarts the clock.
- Using gross income instead of MAGI. MAGI for IRMAA purposes equals your IRS Form 1040 AGI plus tax-exempt interest income. Many filers accidentally use their gross wages or total Social Security benefit, which overstates MAGI and may keep them in a higher tier.
- Missing the 60-day filing window after the determination letter arrives. SSA may grant late-filing extensions for good cause, but good cause must be demonstrated in writing. Missing the window without requesting an extension typically means paying the higher IRMAA through the calendar year.
- Assuming the appeal covers both Part B and Part D automatically. Form SSA-44 covers both Part B and Part D IRMAA surcharges in a single filing. However, if you have a Medicare Advantage plan that incorporates Part D, confirm with your plan administrator whether the Part D surcharge adjustment flows through automatically or requires a separate notification.
2026 IRMAA Brackets: What You Are Currently Paying and What a Successful Appeal Can Reduce
Medicare calculates IRMAA using 2024 MAGI for 2026 premiums. The standard 2026 Part B premium of $202.90 per month applies to single filers with 2024 MAGI at or below $109,000 and joint filers at or below $218,000. Above those thresholds, five surcharge tiers add $81.20 to $487.00 per month to the Part B premium alone, per person. Part D surcharges add an additional $14.50 to $91.00 per month per person on top of your plan's base premium.
The table below shows 2026 Part B totals and Part D surcharges by tier for single filers. Married filing jointly thresholds are exactly double the single-filer thresholds through Tier 3, then diverge above $410,000 joint. Married filing separately is treated as single for IRMAA purposes. A single-filer retiree who retired in late 2024 and dropped from Tier 2 income ($137,001 to $171,000) to base-level income below $109,000 saves $202.90 per month in Part B surcharge plus $37.50 per month in Part D surcharge, totaling $2,884.80 per year from a single SSA-44 filing.
2026 IRMAA Surcharge Tiers by 2024 MAGI, Single Filers| Tier | 2024 MAGI (single) | Part B total/mo | Part B surcharge/mo | Part D surcharge/mo |
|---|
| Base | Under $109,000 | $202.90 | $0 | $0 |
| Tier 1 | $109,001 to $137,000 | $284.10 | +$81.20 | +$14.50 |
| Tier 2 | $137,001 to $171,000 | $405.80 | +$202.90 | +$37.50 |
| Tier 3 | $171,001 to $205,000 | $527.50 | +$324.60 | +$60.40 |
| Tier 4 | $205,001 to $499,999 | $649.20 | +$446.30 | +$83.30 |
| Tier 5 | $500,000 and above | $689.90 | +$487.00 | +$91.00 |

Qualifying Life-Changing Events: What Counts and What Does Not
Federal law defines eight qualifying life-changing events for Form SSA-44: (1) marriage, (2) divorce or annulment, (3) death of a spouse, (4) work stoppage (retirement or job loss), (5) work reduction (reduction in hours or pay), (6) loss of income-producing property beyond your control (such as a natural disaster), (7) loss or reduction of pension income (including pension plan termination or divorce-related pension division), and (8) employer settlement payment in lieu of wages (such as a one-time severance classified as back wages). Three of these account for the vast majority of SSA-44 filings: retirement, death of a spouse, and divorce.
Retirement (work stoppage) is the most common qualifying event. A person who retired in 2025 or early 2026 with 2024 wages that pushed them into a higher IRMAA tier can file SSA-44 using their estimated 2025 or 2026 income, typically just Social Security retirement benefits plus any investment income. Death of a spouse removes the survivor from a joint-filing household, often dropping the survivor from above the $218,000 joint-filer threshold to below the $109,000 single-filer threshold, potentially eliminating IRMAA entirely. Divorce similarly separates two incomes into two separate filing households, and if the lower-earning spouse was being IRMAA-penalized by the combined joint income, SSA-44 allows recalculation on the single-filer basis.
Events that do NOT qualify are equally important to understand. Roth IRA conversions, even very large ones, do not qualify because the conversion is a voluntary action rather than an involuntary income loss. A one-time home sale creating a large capital gain in 2024 does not qualify even if 2025 income dropped substantially. Large IRA required minimum distributions (RMDs) that spike MAGI in one year and then return to normal the following year do not qualify. Inheritances received as distributions from a trust or estate do not qualify. If your high 2024 MAGI resulted from any of these non-qualifying events, you must wait for the automatic recalculation to catch up with your lower 2025 or 2026 income.
Documentation Required by Event Type
Retirement or work stoppage: SSA requires documentation that you actually stopped working. Acceptable documents include a letter from your employer on company letterhead confirming your last day of employment, your final pay stub showing the pay period end date, or a signed letter from a union or professional association confirming retirement. Self-employed retirees should provide the final Schedule C or a signed statement showing business cessation. SSA may also request your most recent W-2 or Social Security earnings record to establish the prior income baseline.
Death of a spouse: Provide a copy of the death certificate. If the deceased spouse had pension income, also provide a letter from the pension administrator confirming that survivor benefits are reduced or eliminated. For Social Security survivor benefits, SSA already has the records internally, but submitting documentation proactively speeds up the SSA-44 review. The surviving spouse's income estimate for the current year should reflect only their own income sources, not the deceased spouse's.
Divorce or annulment: Provide a certified copy of your final divorce decree, which must show the date the divorce was finalized by the court. If your income dropped due to the divorce (for example, a lower-earning spouse who was on a joint return with a high-earning ex-spouse), include documentation of your separate income sources for the current year. A signed divorce settlement or property settlement agreement may supplement the decree but does not replace it. SSA does not accept a divorce filing date, only the finalization date from the court order.
How IRMAA Interacts with Medicare Savings Programs for Lower-Income Enrollees
IRMAA and the Medicare Savings Programs (MSPs) operate at opposite ends of the Medicare income spectrum. IRMAA adds surcharges for higher-income beneficiaries (single MAGI above $109,000 in 2026). MSPs pay the Part B premium entirely and cap cost-sharing for beneficiaries with income below approximately 135% of the Federal Poverty Level, or about $21,546 for a single person in 2026. A retiree who successfully files SSA-44 and drops below the IRMAA threshold has not automatically qualified for MSP, because MSP income limits are far lower than the IRMAA base threshold.
Medicare eligibility itself is not income-gated the way Medicaid is. Everyone turning 65 who meets the work history requirement qualifies for Medicare regardless of income. However, after a successful IRMAA appeal, beneficiaries who find their income has dropped substantially may want to check Medicare Savings Program eligibility separately at their state Medicaid agency, as MSP can eliminate the Part B premium entirely for qualifying low-income enrollees. Apply for MSP through your state Medicaid program, not through SSA.
Frequently Asked Questions
What is the IRMAA appeal window after a life-changing event?
You have 60 days from the date you receive your IRMAA Initial Determination Notice from SSA to file Form SSA-44. However, proactive filing before you receive a formal notice is also accepted and is often faster. If you retired, divorced, or lost a spouse earlier in the year, you can file Form SSA-44 at any time without waiting for the annual determination notice. Missing the 60-day window after receiving a notice does not automatically bar you, but SSA requires written documentation of good cause for any late filing.
Which income year does my 2026 IRMAA surcharge use?
Your 2026 IRMAA is based on your 2024 Modified Adjusted Gross Income (MAGI) as reported on your 2024 federal tax return. MAGI equals your IRS Form 1040 Adjusted Gross Income plus any tax-exempt interest income. SSA uses a two-year lookback because the IRS does not provide finalized income data until roughly 18 months after the tax year ends. Form SSA-44 allows you to substitute a more recent income year if a qualifying life-changing event caused your income to drop since 2024.
What documents do I need to file Form SSA-44 after retiring?
For a retirement or work stoppage filing, gather three documents: (1) a letter from your employer on company letterhead confirming your last day of employment and that the separation is permanent, (2) your final pay stub showing the pay period ending date, and (3) your prior-year IRS Form 1040 so SSA can verify the MAGI they are currently using. Self-employed retirees should provide the final Schedule C or a signed statement attesting to business cessation and the date of closure.
How much can I save by appealing IRMAA after retirement?
Savings depend on which tier you drop from and to. A single retiree moving from Tier 1 (MAGI $109,001 to $137,000) to the base rate saves $81.20 per month on Part B plus $14.50 on Part D, totaling $1,148.40 per year. Moving from Tier 3 ($171,001 to $205,000) to base saves $324.60 per month plus $60.40, totaling $4,620 per year. Moving from Tier 5 (above $500,000) to base saves $487.00 on Part B plus $91.00 on Part D, totaling $6,936 per year per person.
Does the death of a spouse qualify for an IRMAA appeal?
Yes. Death of a spouse is one of the eight explicitly qualifying life-changing events for Form SSA-44. The surviving spouse's income often drops significantly because the joint return is replaced by a single-filer return with only the survivor's income. A surviving spouse who was above the $218,000 joint-filer Tier 1 threshold may fall well below the $109,000 single-filer threshold after the spouse's death, eliminating IRMAA entirely. Document the event with a death certificate and any pension termination letters.
Does divorce qualify for an IRMAA appeal?
Yes. Divorce or annulment is one of the eight qualifying life-changing events. For the appeal to succeed, your income must have actually decreased after the divorce. If you were the lower-earning spouse and the joint MAGI put you in a higher IRMAA tier, divorce separates the incomes and your solo MAGI may fall below the Tier 1 threshold. If you were the higher-earning spouse and your income did not change substantially, you may still owe IRMAA. SSA requires a certified copy of the final court divorce decree, not just the filing date.
Can I file SSA-44 if my income dropped because of a Roth IRA conversion?
No. Roth IRA conversions are not a qualifying life-changing event under SSA rules, even if the conversion caused your 2024 MAGI to spike into a higher IRMAA tier. IRA withdrawals, required minimum distributions, home sale capital gains, and inheritances are also excluded. Only the eight specific events defined by federal law (retirement, divorce, death of spouse, and five others) qualify. If your high MAGI resulted from a Roth conversion, you must wait for the automatic annual recalculation as your 2025 or 2026 MAGI replaces 2024.
What happens if SSA denies my Form SSA-44 request?
A denial of Form SSA-44 is not the end of the process. Within 60 days of the denial letter, you can request a formal reconsideration by SSA. If reconsideration is also denied, you then have 60 days to request a hearing before the Office of Medicare Hearings and Appeals (OMHA). OMHA hearings are conducted by independent administrative law judges and result in binding decisions. The full appeal ladder continues to the Medicare Appeals Council and, in rare cases, federal district court. Approximately 50 percent of denied IRMAA appeals that reach OMHA hearings are reversed, per Medicare appeals data.
