How to Avoid Medicare’s Hidden Income Surcharge
How Idaho, Utah, Colorado & Arizona retirees keep one good income year from becoming two years of higher Medicare premiums?
IRMAA planning strategies matter for one simple reason. A single high-income year can quietly cost you thousands in extra Medicare premiums two years later. IRMAA stands for the Income-Related Monthly Adjustment Amount. It’s a surcharge added to Medicare Part B and Part D premiums once your income crosses a threshold. Most retirees never see it coming, because the trigger year and the bill arrive two years apart. Here’s how to plan around it before it plans around you.
QUICK ANSWER
IRMAA planning strategies come down to one core idea. IRMAA is based on the tax return you filed two years ago, not your income this year. For 2026, the surcharge starts at $109,000 in modified adjusted gross income for single filers, and $218,000 for joint filers. Both figures are based on 2024 tax returns. About 5.1 million Medicare beneficiaries, roughly 7% of all enrollees, paid a Part B IRMAA surcharge in 2025. It’s also a cliff, not a gradual phase-in. One dollar over a threshold triggers the full surcharge for that tier, on both Part B and Part D.
The main levers are timing discretionary income around your MAGI bracket – Roth conversions, capital gains, large withdrawals. It also helps to use qualified charitable distributions to lower reportable income. And it helps to know which life events qualify for an SSA-44 appeal. Retirement, divorce, and the death of a spouse all qualify. A Roth conversion or a required minimum distribution does not.
Why IRMAA Catches Retirees Off Guard
Most tax rules work on a simple calendar. IRMAA doesn’t. It’s based on your modified adjusted gross income from two years earlier, not the year you’re actually paying it. As a result, that gap creates a blind spot. So, a high-income year in 2025 shows up as a higher Medicare premium in 2027. By then, the year itself is over and often forgotten.
The structure adds another wrinkle, too. Federal income tax brackets phase in gradually, but IRMAA doesn’t – it’s a cliff. Cross a threshold by even one dollar, and the full surcharge applies. In fact, it hits your entire premium for that tier, not just the amount over the line. Kiplinger’s coverage of the 2026 brackets put it plainly. In short, go one dollar over, and both your Part B and Part D premiums jump to the next tier.
This isn’t a rare edge case, either. About 5.1 million Medicare beneficiaries paid a Part B IRMAA surcharge in 2025. That’s roughly 7% of all enrollees, according to the Medicare Trustees Report. Even so, for BANDER’s clients, that share tends to run higher. After all, retirement income, Roth conversions, and business sales all push modified adjusted gross income into IRMAA territory. Consequently, that happens more often here than the national average.
2026 vs. 2027 IRMAA Brackets at a Glance
| Tier | 2026 MAGI (Single) | 2027 MAGI (Single, projected) | 2026 Part B Premium | 2027 Part B Premium (projected) |
|---|---|---|---|---|
| Standard | ≤$109,000 | ≤$112,000 | $202.90 | $209.50 |
| Tier 1 | $109,001–$137,000 | $112,001–$141,000 | $284.10 | $293.30 |
| Tier 2 | $137,001–$171,000 | $141,001–$176,000 | $405.80 | $419.00 |
| Tier 3 | $171,001–$205,000 | $176,001–$211,000 | $527.50 | $544.70 |
| Tier 4 | $205,001–$500,000 | $211,001–$499,999 | $649.20 | $670.40 |
| Top Tier | $500,000+ | $500,000+ | $689.90 | $712.30 |
Married filing jointly thresholds run roughly double the single-filer thresholds shown above at every tier – for example, the 2026 standard threshold is $218,000 for joint filers. 2027 figures are Trustees Report projections pending CMS’s official November 2026 announcement. Part D carries its own surcharge on top of Part B, ranging from $14.50 to $91.00 a month in 2026 depending on tier.
Your IRMAA Planning Strategies Roadmap
1. Know the two-year lookback cold.
Your 2026 IRMAA is based on your 2024 tax return. Your 2027 IRMAA will be based on your 2025 return. That gap means today’s income decision doesn’t show up as a Medicare bill for two more years. Model it that far ahead, not just for the current tax year.
2. Treat every threshold as a cliff, not a soft edge.
IRMAA doesn’t phase in. One dollar over a threshold triggers the full surcharge for that entire tier, on both Part B and Part D. Before finalizing a Roth conversion, a capital gain, or a large withdrawal, check the math first. See exactly where it lands relative to the nearest threshold.
3. Coordinate income timing across two years at once, not one.
A Roth conversion decision already has to weigh this year’s tax bracket. Now weigh next year’s IRMAA bracket too, two years out. The right conversion amount is often smaller than a tax-bracket-only analysis would suggest. That’s once the Medicare premium is added to the real cost.
4. Use qualified charitable distributions to manage MAGI.
Once you reach the QCD-eligible age, distributions sent directly from an IRA to charity don’t count as taxable income. That lowers your MAGI, which can keep you under an IRMAA threshold in a year that would otherwise cross it. It’s one of the few levers that reduces taxable income without also reducing what you spend. Starting in 2026, this lever is even stronger, because a QCD sidesteps the new limits on charitable deductions. Our guide to charitable giving tax strategies compares QCDs with the other ways to give.
5. Know exactly which life events qualify for an SSA-44 appeal, and which don’t.
Social Security recognizes eight qualifying events. They are marriage, divorce, the death of a spouse, work stoppage, and work reduction. The list also includes loss of income-producing property, loss of pension income, and an employer settlement payment. A Roth conversion doesn’t qualify on its own. Neither does a large RMD or a taxable home sale. File Form SSA-44 within 60 days of your IRMAA determination letter if one of the eight applies.
6. Plan for the surviving-spouse jump before it happens.
When a spouse dies, tax filing status shifts from joint to single. Joint thresholds sit at roughly double the single thresholds. The same household income can suddenly land two or three tiers higher. The two-year lookback means the bill arrives well after the loss, when it’s easy to miss the connection. Modeling the single-filer bracket now, while both spouses are living, helps. It turns a painful surprise into a plannable transition.
Common IRMAA Planning Scenarios
“I’m planning a large Roth conversion this year.”
Model the conversion amount against next year’s IRMAA threshold, not just this year’s tax bracket. So, see our Roth conversion strategies guide for how the two decisions fit together.
“I’m earning more interest since the Fed’s rate hike.”
Higher rates mean more interest income from CDs and bonds, and that counts toward MAGI. See our post on what the Fed’s rate hike means for retirees for what to watch before you reinvest. If yields keep rising, our post on tax-smart moves for retirees covers how to manage that extra income.
“I just retired, or I’m about to.”
Retirement is a qualifying life event for an SSA-44 appeal. If your income dropped from your working years to retirement, you may qualify for a recalculation. As a result, IRMAA can be based on your current income instead of a higher-earning, two-year-old tax return.
“I recently lost my spouse.”
The death of a spouse qualifies for an SSA-44 appeal. However, it only helps if your actual income also dropped enough to justify a lower bracket. In fact, the filing-status shift from joint to single can offset that drop. So, run the numbers before assuming the appeal will help.
“I just sold my business or my practice.”
A sale year often produces the highest MAGI of your life. As a result, that shows up as an IRMAA surcharge two years later. See our Business Owner Exit Planning guide for how sale structure affects the number that lands on your tax return. In addition, for practice sales specifically, our Physician and Dentist Financial Planning guide covers the same ground.
“I’m weighing how a bigger Medicare premium fits into next year’s budget.”
In fact, our post on the 2027 Medicare Part B premium covers where the premium and COLA are headed next year. That’s before IRMAA is even added on top.
“I’m relocating for retirement.”
IRMAA is a federal surcharge. So, it applies the same way no matter which state you retire in. Moving to Idaho, Utah, Colorado, or Arizona won’t change your IRMAA bracket. However, it can still change how much of your other retirement income is taxed at the state level. See our Mountain West relocation & tax residency guide for that comparison.

Frequently Asked Questions
What is IRMAA and who has to pay it?
IRMAA stands for the Income-Related Monthly Adjustment Amount. It’s a surcharge added to Medicare Part B and Part D premiums for higher-income beneficiaries. About 5.1 million people, roughly 7% of all Medicare enrollees, paid a Part B IRMAA surcharge in 2025.
How much is the IRMAA surcharge in 2026, and what’s projected for 2027?
In 2026, the surcharge starts once modified adjusted gross income crosses $109,000 for single filers. For joint filers, the threshold is $218,000. It adds $81.20 to $487.00 a month to the standard $202.90 Part B premium, depending on tier. Current projections put the 2027 threshold near $112,000 for single filers. Surcharges are projected to range from about $83.80 to $502.80 a month, on top of a projected $209.50 standard premium.
Why is my IRMAA based on income from two years ago?
The Social Security Administration uses your most recently filed tax return available when premiums are set. That’s typically from two years earlier. That lookback gives Social Security verified, finalized income data instead of an estimate. It also means today’s income decisions show up as a Medicare bill two years later.
Can I appeal an IRMAA surcharge?
Yes, in some cases. If you’ve had one of eight qualifying life-changing events since the tax year behind your IRMAA, you may qualify. File Form SSA-44 within 60 days of your determination letter to have your premium recalculated on more current income.
What life events qualify for an IRMAA appeal, and what doesn’t count?
Marriage, divorce, the death of a spouse, work stoppage, and work reduction all qualify. So do loss of income-producing property, loss of pension income, and an employer settlement payment. A Roth conversion, a required minimum distribution, and a taxable home sale don’t qualify on their own. That’s true even though all three can raise your MAGI.
Does a Roth conversion trigger IRMAA?
It can. A Roth conversion adds to your modified adjusted gross income in the year you convert. That can push you into a higher IRMAA bracket two years later. It’s worth modeling the conversion against next year’s IRMAA thresholds, not just this year’s tax bracket. Do that before deciding how much to convert.
What is the "widow penalty," and how can I plan for it?
When a spouse dies, tax filing status shifts from joint to single. Joint IRMAA thresholds sit at roughly double the single thresholds. The same household income can suddenly land two or three tiers higher. Modeling the single-filer bracket in advance, while both spouses are living, helps. It turns a painful surprise into something you can plan around.
Does moving to a different state lower my IRMAA surcharge?
No. IRMAA is a federal surcharge that applies the same way regardless of which state you live in. Relocating can still change how much of your other retirement income is taxed at the state level. It just won’t change your IRMAA bracket.
