I sold my house and my income spiked — will I pay IRMAA forever?

No. IRMAA is reassessed every year based on your tax return from two years prior. If your income was unusually high in one year due to a home sale or other one-time event, your IRMAA surcharge will only apply for the year that corresponds to that high-income tax return. Once your income drops in subsequent years, your premiums will return to the standard amount. You may also be able to file an appeal using SSA Form SSA-44 if you experienced a qualifying life-changing event.

When does SSA notify me about IRMAA?

The Social Security Administration sends an Initial IRMAA Determination notice (Form SSA-RM-0500) in late fall of the year before the surcharge takes effect. For example, you would receive your 2026 IRMAA notice around November or December 2025. The notice explains which bracket you fall into and how much extra you will pay.

Can I appeal IRMAA if my income dropped this year?

You can only appeal IRMAA if you experienced a specific life-changing event recognized by SSA, such as marriage, divorce, death of a spouse, work stoppage, or loss of income-producing property. A general decline in investment income, stock market losses, or voluntary changes to retirement savings do not qualify. If you do have a qualifying event, file SSA Form SSA-44 with supporting documentation.

Does IRMAA apply to Medicare Advantage premiums?

IRMAA applies to your Part B premium, which you pay regardless of whether you have Original Medicare or Medicare Advantage. If your Medicare Advantage plan includes Part D drug coverage, the Part D IRMAA surcharge also applies on top of whatever plan premium you pay. So yes — IRMAA affects Medicare Advantage enrollees through both Part B and Part D surcharges.

I'm married filing separately — are my brackets different?

Yes. If you are married and file a separate tax return, the IRMAA brackets are significantly more restrictive. For 2026, if your individual MAGI is $106,000 or less, you pay the standard premium. But if your MAGI is between $106,001 and $394,000, you jump to the second-highest surcharge tier. Above $394,000, you pay the maximum surcharge. This makes married filing separately much more expensive for IRMAA purposes.

IRMAA in 2026: Income Brackets, Surcharges, Appeals, and Life Events

Q: What if I disagree with SSA's decision on my appeal?

If SSA denies your IRMAA appeal, you have the right to request a reconsideration within 60 days of receiving the decision. If the reconsideration is also unfavorable, you can request a hearing before an Administrative Law Judge (ALJ). Beyond that, you can appeal to the Medicare Appeals Council and ultimately to federal court. Each level of appeal has specific deadlines, so act promptly.

If you earn above a certain threshold, Medicare charges you more. It's called the Income-Related Monthly Adjustment Amount (IRMAA), and it adds surcharges to both your Part B and Part D premiums. About 7% of Medicare beneficiaries pay it — and many don't see it coming until they're already on the hook.

What Is IRMAA?

IRMAA is a surcharge on Medicare Part B and Part D premiums for beneficiaries whose income exceeds certain thresholds. It's not a separate tax — it's an adjustment to your monthly premium based on your Modified Adjusted Gross Income (MAGI) from two years prior.

For 2026, SSA uses your 2024 tax return to determine whether you owe IRMAA. Your MAGI is calculated as your Adjusted Gross Income (AGI) plus any tax-exempt interest income. SSA receives this information directly from the IRS — you don't need to report it yourself.

Common surprise: Someone sells a house, cashes out a 401(k), or realizes a large capital gain — and their income spikes for one year. Two years later, they get hit with IRMAA surcharges they didn't expect. The fix? Plan ahead, and know that you may be able to appeal if a qualifying life event caused the spike.

2026 Part B IRMAA Brackets

The standard Part B premium for 2026 is $202.90/month. Higher earners pay more:

Individual Filing	Joint Filing	Part B Monthly Premium
≤$106,000	≤$212,000	$202.90 (standard)
$106,001–$133,000	$212,001–$266,000	$283.90
$133,001–$167,000	$266,001–$334,000	$405.10
$167,001–$200,000	$334,001–$400,000	$526.30
$200,001–$500,000	$400,001–$750,000	$647.60
Above $500,000	Above $750,000	$768.80

2026 Part D IRMAA Brackets

Part D IRMAA is a separate surcharge added on top of whatever your Part D plan's monthly premium is. The income thresholds are the same as Part B:

Individual Filing	Joint Filing	Part D Monthly Surcharge
≤$106,000	≤$212,000	$0.00
$106,001–$133,000	$212,001–$266,000	$13.70
$133,001–$167,000	$266,001–$334,000	$35.30
$167,001–$200,000	$334,001–$400,000	$57.00
$200,001–$500,000	$400,001–$750,000	$78.60
Above $500,000	Above $750,000	$85.80

How IRMAA Is Calculated

SSA determines your IRMAA using a straightforward formula:

MAGI = Adjusted Gross Income (AGI) + tax-exempt interest income
SSA uses your MAGI from two years prior — your 2024 tax return determines your 2026 IRMAA
The IRS sends your income data to SSA automatically — you don't file anything
IRMAA is reassessed every year, so a one-time income spike only affects one year of premiums

Married filing separately? The brackets are significantly worse. If your individual MAGI exceeds $106,000, you may jump directly to one of the highest surcharge tiers. Couples considering filing separately should factor IRMAA into their tax planning.

Life-Changing Events That Qualify for an IRMAA Appeal

If your income has dropped significantly due to a major life event, you can ask SSA to use your more recent (lower) income instead of the two-year-old tax return. SSA recognizes these specific events only:

Marriage

Your filing status or combined income changed.

Divorce or annulment

You lost a spouse's income or your filing status changed.

Death of spouse

Your household income dropped due to the loss of your spouse.

Work stoppage or reduction

You or your spouse stopped working or significantly reduced hours.

Loss of income-producing property

Due to a disaster, fraud, or other event beyond your control.

Loss of pension

A pension you were receiving was reduced or eliminated.

Employer settlement payment

You received a one-time settlement from a former employer.

These are the ONLY qualifying events. A bad investment year, stock market losses, voluntary early retirement without a work stoppage, or changes to your retirement savings contributions do not qualify for an IRMAA appeal.

How to File an IRMAA Appeal

If you experienced a qualifying life-changing event, here's how to request a new initial determination:

Step 1

Get SSA Form SSA-44

Download the Medicare Income-Related Monthly Adjustment Amount — Life-Changing Event form from ssa.gov or request it from your local SSA office.

Step 2

Document your life-changing event

Gather evidence: a divorce decree, death certificate, employer termination letter, pay stubs showing reduced income, or documentation of property loss.

Step 3

Provide evidence of reduced income

Include proof of your current or expected income — recent pay stubs, a signed statement from your employer, pension notification, or tax professional estimate.

Step 4

Submit to your local SSA office

You can submit in person, by mail, or by calling SSA at 1-800-772-1213 (TTY: 1-800-325-0778). In-person visits may speed up processing.

Step 5

Wait for a decision

SSA typically reviews and responds within a few weeks. They may contact you for additional documentation.

Step 6

Appeal if denied

If SSA denies your request, you can request a reconsideration within 60 days. After that, you can request a hearing before an Administrative Law Judge (ALJ).

Already paying the higher amount? You can appeal even after IRMAA has taken effect. If SSA approves your request, they'll retroactively adjust your premiums and refund any overpayments.

Strategies to Reduce IRMAA Exposure

While you can't avoid IRMAA if your income is genuinely high, smart planning can help you stay below the thresholds — or at least minimize the impact:

Plan Roth conversions carefully: Converting traditional IRA funds to a Roth increases your MAGI in the conversion year. Spread conversions over multiple years to stay below IRMAA brackets.
Use Qualified Charitable Distributions (QCDs): If you're 70½ or older, donating directly from your IRA to charity (up to $105,000 in 2024) reduces your AGI without counting as taxable income.
Time capital gains and large withdrawals: If you know you'll have a high-income year, consider deferring additional capital gains or large retirement account withdrawals to a different tax year.
Coordinate with your financial advisor: A tax-aware retirement income strategy can help you manage which years your MAGI spikes and which years it stays below IRMAA thresholds.

Important: This is general information, not tax or financial advice. IRMAA planning involves complex interactions between Social Security, Medicare, and tax law. Consult a qualified tax professional or financial advisor for strategies specific to your situation.
