Medicare Premiums After Widowhood: IRMAA and SSA-44

The Medicare premium taken from your Social Security this year was, in most cases, priced from a tax return filed two years ago, very likely a joint return that carried your husband’s income alongside your own. That lag can cut both ways. In the first years it may charge you for household income that has already fallen away. Later, once you file alone, it measures your income against thresholds set at half the joint levels in every tier but the top one.

The surcharge is the income-related monthly adjustment amount, or IRMAA: a formula with a known input, a known delay, and a narrow, well-marked door for correction. After reading, you should be able to decide whether to ask Social Security to use a more recent year, what to send with Form SSA-44, how to price a planned conversion or sale, and when a formal appeal is worth filing.

How Social Security sets the surcharge

IRMAA applies to people with Part B, Medicare drug coverage, or both, whose modified adjusted gross income, or MAGI, exceeds the threshold for their tax filing status. For this purpose MAGI is adjusted gross income plus tax-exempt interest. Municipal bond interest that escapes federal income tax does not escape this calculation.

You do not report the figure. The IRS sends it to Social Security, which uses the most recent year available: generally the return from two years before the premium year, and not more than three. Your 2026 premiums are therefore generally based on your 2024 return. CMS estimates that the adjustment affects roughly 8% of people with Part B.

The 2026 brackets and what they cost

CMS set the 2026 standard Part B premium at $202.90 a month. Above the first threshold, the total Part B premium and the Part D adjustment rise in steps, per person:

MAGI, individual return	MAGI, joint return	2026 Part B premium	2026 Part D adjustment
$109,000 or less	$218,000 or less	$202.90	$0.00
Over $109,000 to $137,000	Over $218,000 to $274,000	$284.10	$14.50
Over $137,000 to $171,000	Over $274,000 to $342,000	$405.80	$37.50
Over $171,000 to $205,000	Over $342,000 to $410,000	$527.50	$60.40
Over $205,000, under $500,000	Over $410,000, under $750,000	$649.20	$83.30
$500,000 or more	$750,000 or more	$689.90	$91.00

Three features matter more than any single number. The steps are cliffs, not slopes: one dollar over a line moves the whole premium to the next tier. The Part D amount is added to your plan’s own premium. And only married filing jointly uses the joint column. Single, head-of-household, and qualifying surviving spouse filers use the individual column. Married filing separately has a steeper schedule of its own: if you lived with your spouse at any time during the year, MAGI over $109,000 brings the $649.20 Part B premium and $83.30 Part D adjustment, and $391,000 or more the top tier. Weigh that before choosing a separate return for the year of death.

How widowhood moves you between the columns

IRS Publication 501 treats you as married for the whole year in which your spouse dies, so you may file a joint return for that year if you have not remarried; it is the last joint return you can file with him. Qualifying surviving spouse status can follow for two years, but only if several tests are met (including keeping up a home for a qualifying child)and it is not a joint return. For IRMAA, Social Security places qualifying surviving spouse status in the same threshold table as single and head-of-household filers, not the joint table.

Set that beside the lookback and the sequence is predictable. Suppose your husband died in 2026. Your 2026 and 2027 premiums rest on the joint returns for 2024 and 2025, and your 2028 premium on the joint return for 2026. Only in 2029, drawing on your 2027 return, does Social Security first measure you against the individual column.

Two different things can happen along the way. The early joint returns may include income that ended with his death: salary, business draws, a pension without a survivor benefit. That is where a review helps. Later, your own income, now read against the individual column, may land in a higher tier than the couple’s did. No form corrects that. It is a planning question for a multi-year tax map for filing alone, modelled alongside how Social Security benefits are taxed after widowhood.

Death of a spouse is a qualifying life-changing event

Social Security’s list of life-changing events is exclusive: death of a spouse, marriage, divorce or annulment, work reduction, work stoppage, loss of income-producing property, loss of employer pension income, and a settlement payment from an employer. When one causes a significant reduction in MAGI, meaning one that lowers or eliminates your IRMAA, you may ask for a new initial determination using a more recent tax year.

The standard of proof is more humane than many expect. You attest, under penalty of perjury, that the event caused the reduction; the agency does not examine which kinds of income make up the MAGI. The death may have occurred at any time in the past.

The premium looks backward by design; the review is how you bring it up to date.

What to send with Form SSA-44

Form SSA-44 is optional; you may also make the request with a Social Security office. Either way, assemble:

1. Proof of death, if Social Security’s records do not already show it.
2. An estimate of your MAGI and filing status for the year you want used, or a signed copy of the more recent return if it shows the reduction.
3. A second estimate for the following premium year. Without one, Social Security applies your first estimate to that year too.
4. The signed return once filed, if you began with an estimate. If you filed electronically, print and sign a copy.

Timing governs the result. When the death affects income in the current year, the new determination takes effect from January of that year, or from your first month of Part B if later. If the death falls in the current year but will not lower your income until the next, it takes effect the following January. It ordinarily does not reach an earlier premium year, with one exception worth a calendar note: if the death occurred between October 1 and December 31 and affected that year’s income, a request received by March 31 of the next year can reach back to January of the year of death.

One-time income the review will not look past

The review is for income that has fallen because life changed, not for a year that was high because income was realized. Social Security’s manual names capital gains from the sale of property, conversion of an IRA, and cashing bonds as non-qualifying events, and the voluntary sale of income-producing property does not qualify either.

That list covers most of the large decisions of the first years: a Roth conversion, the sale of a concentrated position, a family business, or rental property. Each can raise premiums two years later, and no form will cure it. The rule is fixed; the recommendation is to price it in advance. Suppose a sale lifts an individual filer’s MAGI above $500,000. At 2026 rates, Part B would cost $689.90 rather than $202.90 a month, or $5,844 more for the year, plus $1,092 in Part D adjustments. That is rarely a reason to forgo a sound transaction. It may be a reason to spread a conversion across years, or to pair a gain with a year of low income.

Your home is treated differently. Under IRS Publication 523, a surviving spouse who sells a main home within two years of the death, has not remarried, has not used the exclusion too recently, and meets the ownership and residence tests may exclude up to $500,000 of gain rather than $250,000. Basis is separate and depends on ownership. IRS Publication 551 says the inherited interest generally takes a date-of-death basis; for a qualified joint interest, the survivor keeps the adjusted basis of her own half and adds the basis of the inherited half. If the home was community property and at least half its value was includible in the decedent’s gross estate, both halves generally receive the date-of-death basis. Confirm title and state-law characterization before calculating gain. Gain properly excluded from income does not enter IRMAA MAGI. Keeping the house or selling it sets out the rest of that decision.

Qualified charitable distributions and other quiet levers

If you are at least 70½ and give to charity, the qualified charitable distribution is the cleanest lever available. A QCD is paid directly by your IRA trustee to an eligible charity, and under IRS Publication 590-B it counts toward your required minimum distribution. For 2026, IRS Notice 2025-67 raises the annual exclusion to $111,000, up from $108,000 for 2025. Because a QCD within that limit never enters income, it never enters MAGI.

Take the distribution yourself and write the check, and the result differs: the distribution is income, and the gift becomes an itemized deduction figured against adjusted gross income rather than a reduction of it. Qualified charitable distributions in 2026 covers eligible recipients, direct-transfer mechanics, reporting, and the acknowledgment the IRS expects.

Two smaller points. Because tax-exempt interest is added back, a move into municipal bonds may cut income tax without cutting MAGI. And because the tiers are cliffs, a year-end look at realized gains is worth an adviser’s hour when you are near a line.

Reviews, reconsiderations, and appeals

Most corrections need no appeal. If you qualify for a new initial determination, Social Security’s guidance says an appeal is usually unnecessary, though you may file both at once. If the IRS figure itself is wrong, correction begins with the IRS; Social Security acts on proof of the error or an amended return.

An appeal is for disagreeing with the determination. You may request reconsideration within 60 days of receiving the IRMAA notice, with receipt presumed five days after the notice date. Beyond that lie a hearing before an administrative law judge in the Office of Medicare Hearings and Appeals, review by the Medicare Appeals Council, and federal court. A predetermination notice describes a planned action and carries no appeal rights; answer it with a request for a new determination if you have a qualifying event.

Questions to settle before you contact Social Security

1. Which tax year and filing status did the IRMAA notice use, and does that return still describe your household?
2. Would your current-year MAGI, on your current filing status, lower or remove the adjustment under the 2026 table?
3. Does Social Security’s record already show the death?
4. Can you estimate this year’s and next year’s MAGI, including tax-exempt interest?
5. Did the death fall between October 1 and December 31, making March 31 the date to meet?
6. Are you within 60 days of the notice, and should a review request and a reconsideration be filed together?
7. Which planned conversions or sales will surface in premiums two years later, and has your adviser priced them?
8. If you are 70½ or older, are charitable gifts from your IRA made as QCDs?
9. When will your first single-filer return become the lookback year, and which tier does your projected income imply?
