No, IRMAA surcharges are not permanent. The Social Security Administration (SSA) recalculates your IRMAA every single year based on your Modified Adjusted Gross Income (MAGI) from two years prior. If your income drops below the threshold in a future tax year, your surcharge drops right along with it — or disappears altogether.
The governing statute behind IRMAA is Section 1839(i) of the Social Security Act, as amended by Section 811 of the Medicare Modernization Act. This law requires higher-income Medicare beneficiaries to pay a larger share of Part B and Part D costs. The immediate consequence: roughly 8% of all Medicare beneficiaries pay more each month — sometimes thousands more each year — for the exact same coverage everyone else receives.

What Is IRMAA and How Does It Work?
IRMAA stands for Income-Related Monthly Adjustment Amount. It is an extra charge added on top of your standard Medicare Part B and Part D premiums. You do not receive better coverage, expanded benefits, or any additional services. It is purely a higher cost for the same Medicare coverage that everyone else gets.
The Centers for Medicare & Medicaid Services (CMS) determines IRMAA brackets each fall. The SSA then uses your tax return from two years prior to figure out which bracket you fall into. For 2026, the SSA uses your 2024 tax return to set your premiums. By the time you receive the surcharge notice, the income that triggered it is already in the past.
This is called the two-year lookback rule, and it is the single biggest source of frustration for retirees. A large Roth conversion in 2024, for example, would not show up as an IRMAA surcharge until 2026. The SSA determines your bracket during the fourth quarter of the prior year because the most recently filed tax return is the latest data point the IRS can provide.
What Counts as MAGI for IRMAA
MAGI for IRMAA purposes is not a single line on your tax return. You start with your Adjusted Gross Income (AGI) on Line 11 of Form 1040 and add back certain items, most notably tax-exempt interest from municipal bonds. This means muni bond income, which many retirees rely on for “tax-free” income, still counts toward IRMAA. Items that increase your MAGI include:
- Wages and self-employment income
- Taxable interest and dividends
- Capital gains from selling stocks, funds, or property
- IRA distributions and pension income
- Up to 85% of Social Security benefits (if taxable)
- Rental income and Schedule 1 items
- Tax-exempt interest (added back on top of AGI)
Why IRMAA Surcharges Are Not Permanent
The most important thing to understand is that IRMAA resets every calendar year. The SSA performs a new determination each year based on the most recent tax data the IRS provides. There is no “lock-in” period. If your MAGI drops below the threshold in a future year, your surcharge goes away — automatically.
Here is a real-world example. Say you sell a rental property in 2024 and report $300,000 in capital gains on your 2024 tax return. In 2026, you will receive an IRMAA surcharge because the SSA sees that elevated 2024 income. But if your 2025 income drops back to $100,000, your 2027 premiums will reflect that lower income and the surcharge disappears.
The annual recalculation means IRMAA is temporary by design. However, if your income stays above the threshold year after year — as it does for many retirees with pensions, RMDs, and investment income — IRMAA can feel permanent even though the law treats each year as a separate determination.
2026 IRMAA Brackets and Surcharge Amounts
For 2026, the standard Medicare Part B premium is $202.90 per month. The IRMAA income brackets increased roughly 3% from 2025, while the surcharges themselves rose approximately 9%. Below are the 2026 brackets based on your 2024 MAGI.
2026 Part B and Part D IRMAA (Single and Joint Filers)
| 2024 MAGI (Single / Joint) | Part B Surcharge | Part D Surcharge | Total Part B Premium |
|---|---|---|---|
| ≤ $109,000 / ≤ $218,000 | $0 | $0 | $202.90 |
| $109,001–$137,000 / $218,001–$274,000 | $81.20 | $14.50 | $284.10 |
| $137,001–$171,000 / $274,001–$342,000 | $202.90 | $37.50 | $405.80 |
| $171,001–$205,000 / $342,001–$410,000 | $324.60 | $60.40 | $527.50 |
| $205,001–$499,999 / $410,001–$749,999 | $446.30 | $83.30 | $649.20 |
| ≥ $500,000 / ≥ $750,000 | $487.00 | $91.00 | $689.90 |
2026 Married Filing Separately
Married Filing Separately (MFS) filers who lived with their spouse at any time during the tax year face a much harsher IRMAA schedule. There are only two brackets:
| 2024 MAGI (MFS) | Part B Surcharge | Part D Surcharge |
|---|---|---|
| ≤ $109,000 | $0 | $0 |
| $109,001–$390,999 | $649.20 | $83.30 |
| ≥ $391,000 | $689.90 | $91.00 |
Notice the massive jump. A single filer at $110,000 pays an $81.20 Part B surcharge. A married-filing-separately filer at $110,000 pays $649.20. This is why financial advisors almost always warn against filing separately if either spouse is on Medicare unless the tax savings dramatically outweigh the IRMAA penalty.
The Cliff Effect: How $1 Costs You Thousands
IRMAA uses hard cliffs, not a gradual sliding scale. Going even $1 over a bracket boundary triggers the full surcharge for that entire tier — nothing is prorated. This makes precision planning a requirement.
Consider a married couple filing jointly in 2026. Their MAGI is $218,001 — just one dollar above the first threshold. That single dollar triggers an extra $81.20 per month in Part B and $14.50 per month in Part D, per person.
| Scenario | Annual IRMAA Cost (Per Person) | Annual IRMAA Cost (Couple) |
|---|---|---|
| MAGI of $218,000 (just under) | $0 | $0 |
| MAGI of $218,001 (just over) | $1,148.40 | $2,296.80 |
That is $2,296.80 in extra premiums triggered by one dollar. And at the highest bracket, a married couple both on Medicare pays an extra $13,872 per year combined — ($487 + $91) × 2 persons × 12 months. This cliff design makes IRMAA unlike almost any other part of the U.S. tax code.
Three Common Scenarios That Trigger IRMAA
Scenario 1: The Roth Conversion Surprise
Linda, age 66, converts $150,000 from her traditional IRA to a Roth IRA in 2024. Her other income is $90,000. Her total MAGI for 2024 becomes $240,000, pushing her into the second IRMAA bracket for 2026.
| Action | Consequence |
|---|---|
| Converts $150,000 from traditional IRA to Roth | 2024 MAGI rises to $240,000 |
| SSA reviews 2024 tax return | 2026 IRMAA surcharge triggered |
| Part B surcharge: $81.20/month | Extra $974.40 per year |
| Part D surcharge: $14.50/month | Extra $174.00 per year |
| Total extra cost | $1,148.40 for 2026 |
Had Linda split the conversion into two smaller amounts across 2024 and 2025, she could have stayed under $218,000 in both years and avoided IRMAA entirely. Timing Roth conversions is one of the most powerful IRMAA planning tools. The key is to start and complete conversions at least three years before Medicare enrollment because of the two-year lookback.
Scenario 2: The Retirement Transition
Mark, age 65, retires in December 2024 after earning $250,000 that year. In 2025, his only income is $45,000 from Social Security and a small pension. Despite his lower 2025 income, the SSA bases his 2026 premiums on his 2024 earnings of $250,000. He receives an IRMAA notice.
| Action | Consequence |
|---|---|
| Earned $250,000 in final working year (2024) | 2024 MAGI exceeds $218,000 threshold |
| Retires December 2024 | 2025 income drops to $45,000 |
| SSA uses 2024 return for 2026 premiums | IRMAA surcharge assessed for 2026 |
| Files Form SSA-44 citing “Work Stoppage” | SSA reviews current income instead |
| Appeal approved | Surcharge reduced or eliminated; refund issued retroactively |
Mark must file the appeal himself. The SSA does not automatically know he retired. He may also need to file a second SSA-44 the following year (for 2027) because the two-year lookback for 2027 still references his 2025 income, which may also need correction.
Scenario 3: Death of a Spouse
Carol and Jim filed jointly with a combined MAGI of $210,000 in 2024. Jim passes away in early 2025. Carol’s income drops to $80,000. However, her 2026 premiums are based on the 2024 joint return of $210,000. Even though that is under the joint threshold of $218,000, Carol now files as a single filer — and the single threshold is $109,000.
| Action | Consequence |
|---|---|
| Joint MAGI of $210,000 in 2024 | Below joint threshold of $218,000 |
| Jim passes away in 2025 | Carol files as single for 2025 |
| SSA applies 2024 joint income to Carol as single filer | $210,000 exceeds single threshold of $109,000 |
| Carol files SSA-44 citing “Death of Spouse” | SSA reassesses using current income of $80,000 |
| Appeal approved | Surcharge eliminated; possible retroactive refund |
This scenario catches many surviving spouses off guard. The shift from joint to single filing thresholds can create an IRMAA surcharge even when income decreases.
How to Appeal IRMAA: Form SSA-44 Step by Step
If you experience a qualifying life-changing event, you can request a new initial determination from the SSA using Form SSA-44. You have 60 days from receiving your IRMAA notice to file, though you can technically appeal at any time. The sooner you file, the sooner you stop overpaying.
The Eight Qualifying Life-Changing Events
The SSA recognizes only these eight specific events:
- Death of a spouse
- Marriage
- Divorce or annulment
- Work stoppage (retirement, layoff, disability)
- Work reduction (full-time to part-time)
- Loss of income-producing property (disaster, fraud, theft)
- Loss of employer pension income
- Receipt of a settlement payment from a current or former employer
This list is exclusive. Selling a home for a large profit, taking a one-time IRA distribution, or receiving an inheritance does not qualify as a life-changing event. The drop in income must be tied directly to one of these eight events.
Five Steps to Complete Form SSA-44
Step 1 — Identify the Life-Changing Event. Select which of the eight events applies to you. You can only choose one per form. Most retirees select Work Stoppage.
Step 2 — Document Your Reduced Income. Enter the tax year of your event, your Adjusted Gross Income, your tax-exempt interest income, and your filing status. Pull these numbers directly from your Form 1040.
Step 3 — Estimate Next Year’s MAGI. If your life-changing event happened in 2025, you may use your estimated 2026 MAGI if your income was not reduced until 2026 or if it will be lower in 2026 than 2025.
Step 4 — Attach Documentation. Provide evidence of both your MAGI and the event itself. For work stoppage, a signed statement under penalty of perjury confirming you stopped working is sufficient, along with your tax return. For divorce, include the divorce decree. For death of a spouse, include the death certificate.
Step 5 — Sign and Submit. You can submit the form online through your my Social Security account, in person at your local SSA office, or by mail.
What Happens After You File
Appeals take 30 to 90 days to process. About 50% of appeals succeed when proper documentation is provided. If approved, the adjustment may be retroactive to the date of your life-changing event, meaning you could receive a refund for months of overpaid premiums.
If your initial request is denied, you have multiple levels of formal appeal. You start with a Reconsideration using Form SSA-561-U2, then move to an Administrative Law Judge (ALJ) hearing, then the Medicare Appeals Council, and finally Federal Court. Each level adds months to the process, but they exist to protect your rights.
One critical nuance: IRMAA is recalculated on a calendar-year basis. Even if your 2026 appeal succeeds, the SSA will reassess you for 2027 based on your 2025 return. If that return also shows elevated income, you will need to file a new SSA-44 for that year. Many retirees end up filing two consecutive appeals due to the two-year lookback window.
Strategies to Reduce or Avoid IRMAA
Roth Conversions
Moving money from a traditional IRA to a Roth IRA means future withdrawals are tax-free and do not count toward your MAGI. The catch: the conversion itself is taxable income in the year you convert, which can push you into an IRMAA bracket two years later. The ideal window for conversions is before age 63 — because most people enroll in Medicare at 65, and income before 63 will not affect Medicare premiums. Spread conversions across low-income years and stay just under the IRMAA thresholds each year.
Qualified Charitable Distributions (QCDs)
If you are 70½ or older and have a traditional IRA, you can transfer funds directly to a qualified charity. The distribution counts toward your Required Minimum Distribution (RMD) but is excluded from taxable income. For 2025, the limit is $108,000 per person. This directly lowers your MAGI and can reduce or eliminate IRMAA two years later. One critical rule: the money must go directly from your IRA custodian to the charity. If it passes through your hands first, it counts as taxable income.
Qualified Longevity Annuity Contracts (QLACs)
A QLAC is a deferred annuity purchased with funds from a traditional IRA or 401(k). The amount invested in a QLAC is excluded from your RMD calculation until payments begin (no later than age 85). Lower RMDs mean lower MAGI, which can keep you below IRMAA thresholds. The SECURE 2.0 Act removed the previous 25% cap, and the maximum QLAC purchase is now $200,000. The trade-off is that your money is locked up until payments start, and you lose access to those funds in the interim.
Tax-Efficient Investment Management
High-turnover mutual funds generate frequent capital gains distributions that increase your MAGI. Switching to low-turnover, passive index funds reduces unnecessary capital gains. High-dividend funds also increase taxable income. Placing dividend-paying investments inside tax-deferred or Roth accounts can shelter that income from the IRMAA calculation.
Income “Bunching” Strategy
Rather than spreading income across multiple years near the IRMAA threshold, some advisors recommend taking the hit in one year and keeping other years clean. For example, if you must sell appreciated stock, do it all in one year. You pay IRMAA for one two-year cycle instead of spreading a smaller amount across several years and paying the surcharge for four or six years.
Municipal Bond Awareness
Many retirees invest in municipal bonds for “tax-free” interest income. While muni bond interest is exempt from federal income tax, it is added back to your AGI to calculate MAGI for IRMAA purposes. A large municipal bond portfolio can push you over an IRMAA threshold even if it does not affect your income tax bill.
Mistakes to Avoid
Ignoring the two-year lookback. The number-one mistake is not planning far enough ahead. Your 2024 income determines your 2026 IRMAA. If you wait until 2026 to worry about it, you are two years too late.
Converting too much to Roth in a single year. A $500,000 Roth conversion creates a massive MAGI spike. It is almost always better to spread conversions across multiple low-income years while keeping each year below the IRMAA threshold.
Filing Married Filing Separately without running the numbers. The MFS IRMAA brackets are punitive. A spouse at $110,000 MAGI who files separately pays a $649.20 Part B surcharge instead of $81.20. The tax savings from filing separately almost never outweigh the IRMAA penalty.
Forgetting that Social Security income is partially taxable. Up to 85% of Social Security benefits can be included in your MAGI. Combined with RMDs and investment income, this can push you over a cliff without you realizing it.
Overlooking capital gains from mutual fund distributions. Even if you do not sell a single share, your mutual fund can distribute capital gains at year-end. These surprise distributions increase your MAGI and can trigger an IRMAA bracket jump.
Assuming the SSA will automatically adjust your premiums. If your income drops because of a qualifying life-changing event, you must proactively file Form SSA-44. The SSA will not automatically know you retired or lost a spouse. Without an appeal, you keep paying the elevated premium.
Not filing a second SSA-44 the following year. Because IRMAA is recalculated each calendar year, a successful 2026 appeal does not carry over to 2027. If 2025 income (which drives your 2027 premiums) also triggers IRMAA, you need a fresh appeal.
Do’s and Don’ts
Do’s
- ✅ Do monitor your MAGI every year — check Line 11 of your 1040 plus tax-exempt interest to estimate your IRMAA bracket.
- ✅ Do start Roth conversions early — ideally before age 63, to avoid the two-year lookback period hitting your Medicare years.
- ✅ Do use QCDs if you are 70½ or older — they satisfy RMDs while keeping income off your MAGI.
- ✅ Do file Form SSA-44 immediately after experiencing a qualifying life-changing event — delays mean continued overpayment.
- ✅ Do coordinate with your spouse — joint filers need a combined strategy because both incomes factor into one threshold.
Don’ts
- ❌ Don’t assume IRMAA is permanent — it resets every year based on fresh tax data.
- ❌ Don’t ignore municipal bond interest — it is tax-free for income tax but counts toward MAGI for IRMAA.
- ❌ Don’t file Married Filing Separately without calculating the IRMAA penalty — the brackets are dramatically worse for MFS filers.
- ❌ Don’t make a large Roth conversion in the same year or two years before enrolling in Medicare — the income spike triggers IRMAA.
- ❌ Don’t wait for the SSA to fix things — you must proactively appeal using SSA-44 after a life-changing event.
Pros and Cons of Appealing IRMAA
Pros
- 💵 Potential refund — if approved, the adjustment can be retroactive to the date of the event, meaning you may get months of overpaid premiums back.
- 📉 Immediate premium reduction — once processed, your monthly Part B and D costs drop going forward.
- 📝 Straightforward paperwork — Form SSA-44 is a simple five-step form; you do not need a lawyer.
- 🕐 Relatively fast — most appeals are processed in 30 to 90 days.
- 🔁 Multiple appeal levels — if your initial request is denied, you can escalate through four levels of formal appeals.
Cons
- ⏳ Processing delays — some appeals take up to four months, especially during high-volume periods.
- 📄 Must be repeated annually — a successful 2026 appeal does not carry over to 2027.
- 🚫 Limited qualifying events — the SSA’s list of eight events is exclusive; if your situation does not fit, you cannot appeal.
- ⚖️ About 50% success rate — half of appeals are denied, often due to inadequate documentation.
- 💸 You continue paying during the process — until the appeal is approved, your elevated premiums remain in effect.
2025 vs. 2026 IRMAA: What Changed
| Detail | 2025 | 2026 |
|---|---|---|
| Standard Part B Premium | $185.00/month | $202.90/month |
| First IRMAA Threshold (Single) | $106,000 | $109,000 |
| First IRMAA Threshold (Joint) | $212,000 | $218,000 |
| Lowest Part B Surcharge | $74.00/month | $81.20/month |
| Highest Part B Surcharge | $443.90/month | $487.00/month |
| Lowest Part D Surcharge | $13.70/month | $14.50/month |
| Highest Part D Surcharge | $85.80/month | $91.00/month |
| Tax Year Used | 2023 return | 2024 return |
The income thresholds rose about 3% in 2026, tracking inflation. However, the surcharges increased roughly 9%, outpacing the threshold adjustments. This means even if your income stayed flat, you could face higher surcharges.
Key Entities and How They Interact
The Social Security Administration (SSA) receives your tax data from the IRS and determines whether you owe an IRMAA. The SSA sends your IRMAA determination letter and processes Form SSA-44 appeals.
The Internal Revenue Service (IRS) provides the SSA with your MAGI from your most recently filed tax return. This data-sharing is authorized by Section 1839(i) of the Social Security Act.
The Centers for Medicare & Medicaid Services (CMS) sets the standard Part B premium, the IRMAA brackets, and the surcharge amounts each fall. These figures are published in the Federal Register and take effect the following January.
The Office of Medicare Hearings and Appeals (OMHA) handles Level 2 ALJ hearings if your SSA reconsideration is denied. This is part of the formal appeals process available to all beneficiaries.
Understanding how these entities work together helps you navigate the system. The IRS provides the data, CMS sets the rules, the SSA enforces them, and OMHA adjudicates disputes.
FAQs
Is IRMAA a one-time charge?
No. IRMAA is assessed monthly on both Part B and Part D premiums. It recalculates each calendar year based on your MAGI from two years prior.
Does IRMAA go away when my income drops?
Yes. When your MAGI falls below the threshold in a future tax year, the surcharge is removed automatically in the corresponding premium year, two years later.
Can I appeal IRMAA if I sold my house?
No. A home sale is considered a one-time income event. It does not appear on the SSA’s list of eight qualifying life-changing events.
Does Roth IRA income count toward IRMAA?
No. Qualified Roth IRA withdrawals are tax-free and are not included in your MAGI, so they do not trigger IRMAA.
Do both spouses pay IRMAA?
Yes. If both spouses are enrolled in Medicare and their joint MAGI exceeds the threshold, each spouse pays the full surcharge individually.
Can I file Married Filing Separately to avoid IRMAA?
No, in most cases. The MFS IRMAA brackets are far more punitive, and the increased tax liability usually outweighs any IRMAA savings.
Does Medicare Advantage have IRMAA?
Yes. IRMAA applies to all Medicare Part B enrollees, including those on Medicare Advantage plans, because Part B is the foundation of both Original Medicare and Medicare Advantage.
How long does an IRMAA appeal take?
Approximately 30 to 90 days for the initial Form SSA-44 request. Formal appeals through reconsideration and ALJ hearings can add several additional months.
Does tax-exempt bond interest affect IRMAA?
Yes. Tax-exempt interest from municipal bonds is added back to your AGI when calculating MAGI for IRMAA, even though it is not subject to federal income tax.
Can I appeal IRMAA more than once?
Yes. You can — and often must — file a new SSA-44 each year that IRMAA is assessed, because each year is a separate determination based on a different tax return.
