2026 IRMAA Brackets: What Higher-Income Medicare Beneficiaries Need to Know
If you are enrolled in Medicare and your income is above a certain threshold, you may already have noticed something on your premium statement that caught you off guard: a surcharge called IRMAA. Short for Income-Related Monthly Adjustment Amount, IRMAA is the mechanism through which higher-income Medicare beneficiaries pay more for Part B and Part D coverage than the standard premium.
For 2026, the standard Medicare Part B premium is $202.90 per month. But if your modified adjusted gross income (MAGI) exceeds specific thresholds, you could pay significantly more — up to $689.90 per month for Part B alone, plus an additional surcharge on your Part D prescription drug coverage.
Here is what you need to know about how IRMAA works, what the 2026 brackets look like, and what options are available if your income has changed since the tax return the Social Security Administration used to determine your surcharge.
How IRMAA Works: The Two-Year Lookback
The most important thing to understand about IRMAA is that it operates on a two-year delay. Your 2026 Medicare premiums are based on your 2024 tax return — the most recent return the Social Security Administration (SSA) has on file when it determines your adjustment.
This means that if your income was higher in 2024 than it is today — perhaps because you sold a property, received an inheritance, cashed out a retirement account, or had a particularly strong year in business — you could be paying IRMAA surcharges in 2026 based on income you no longer have.
For many Medicare beneficiaries, this two-year lag is the source of real frustration. You might be living on a fixed retirement income now, but the SSA is looking back at a year when you were still working or had a one-time income event.
The 2026 IRMAA Brackets
The SSA uses your tax filing status and MAGI to place you in one of six income tiers for Part B, and six tiers for Part D. The higher your income, the higher the surcharge.
Part B IRMAA Tiers (Monthly Premiums)
Single Filers:
- $109,000 or less: $202.90 (standard premium, no IRMAA)
- $109,001 – $137,000: $284.10 (IRMAA surcharge: $81.20)
- $137,001 – $171,000: $405.80 (IRMAA surcharge: $202.90)
- $171,001 – $205,000: $527.50 (IRMAA surcharge: $324.60)
- $205,001 – $499,999: $649.20 (IRMAA surcharge: $446.30)
- $500,000 or more: $689.90 (IRMAA surcharge: $487.00)
Married Filing Jointly:
- $218,000 or less: $202.90 (standard premium, no IRMAA)
- $218,001 – $274,000: $284.10 (IRMAA surcharge: $81.20)
- $274,001 – $342,000: $405.80 (IRMAA surcharge: $202.90)
- $342,001 – $410,000: $527.50 (IRMAA surcharge: $324.60)
- $410,001 – $749,999: $649.20 (IRMAA surcharge: $446.30)
- $750,000 or more: $689.90 (IRMAA surcharge: $487.00)
Married Filing Separately (living apart from spouse):
- $109,000 or less: $202.90 (standard premium, no IRMAA)
- $109,001 – $390,999: $649.20 (IRMAA surcharge: $446.30)
- $391,000 or more: $689.90 (IRMAA surcharge: $487.00)
The jump from one tier to the next can be substantial. Going from the second tier to the third, for example, adds over $120 per month to your Part B premium — that is more than $1,400 per year in additional costs.
Part D IRMAA Surcharges
On top of your Part B adjustment, IRMAA also applies a monthly surcharge to your Medicare Part D prescription drug coverage. These surcharges are added to whatever your Part D plan premium already costs:
Single Filers:
- $109,000 or less: $0 (no IRMAA)
- $109,001 – $137,000: $14.50
- $137,001 – $171,000: $37.50
- $171,001 – $205,000: $60.40
- $205,001 – $499,999: $83.30
- $500,000 or more: $91.00
Married Filing Jointly:
- $218,000 or less: $0 (no IRMAA)
- $218,001 – $274,000: $14.50
- $274,001 – $342,000: $37.50
- $342,001 – $410,000: $60.40
- $410,001 – $749,999: $83.30
- $750,000 or more: $91.00
For someone in the highest tier, the combined Part B and Part D IRMAA surcharges could add more than $578 per month — nearly $7,000 per year — on top of their standard Medicare costs.
Can You Appeal? The SSA-44 Process
Here is the part many beneficiaries do not know: if your income has dropped due to a qualifying life-changing event, you can appeal your IRMAA surcharge.
Form SSA-44 (Medicare Income-Related Monthly Adjustment Amount — Life-Changing Event) allows you to ask the Social Security Administration to re-evaluate your IRMAA based on your current income rather than the two-year-old tax return.
Qualifying life-changing events include:
- Marriage or divorce
- Death of a spouse
- Retirement or a significant reduction in work hours
- Reduction or loss of income-producing property (such as selling a business)
- Loss of income from a pension (not Social Security benefits)
- An employer settlement payment
If any of these events occurred and your income has genuinely decreased, filing SSA-44 could lower your IRMAA surcharge for the current year. The form requires documentation — you will need to provide evidence of both the life-changing event and your reduced income.
Timing matters. The SSA processes these requests on a rolling basis, so the sooner you submit, the sooner your premium adjusts. Filing at the start of the year gives you the best chance of reducing your costs for as many months as possible.
Planning Ahead: Strategies to Manage IRMAA
While the two-year lookback means you cannot change what has already happened, you can plan ahead to manage future IRMAA exposure. Here are some strategies worth discussing with a financial advisor or insurance professional:
- Roth conversions in lower-income years: Converting traditional IRA funds to a Roth IRA during years when your income is lower can help manage future MAGI. Roth withdrawals do not count toward MAGI in retirement.
- Capital gains timing: If you are approaching Medicare eligibility, the timing of asset sales matters. A large capital gain in your early 60s could affect your premiums at 65 and beyond.
- Charitable giving strategies: Donating appreciated assets directly to charity can reduce taxable income without affecting your cash flow.
- Income-aware withdrawals: When drawing from retirement accounts, the order and timing of withdrawals can influence your MAGI. Strategic sequencing may help keep you in a lower tier.
These are not one-size-fits-all solutions. What works depends on your full financial picture — your income sources, your assets, your goals, and your timeline. A conversation with a knowledgeable advisor can help you make informed decisions that align with your specific situation.
The Bottom Line
IRMAA catches many Medicare beneficiaries off guard because the two-year delay means you are paying based on a financial snapshot that may no longer reflect your current reality. Whether your income has dropped due to retirement, a life event, or simply the natural transition from working years to fixed-income years, the surcharge can feel like an unfair penalty.
But it is not a penalty — it is a structured adjustment based on income. Understanding what triggers it, how the brackets work, and what options exist for appeal or planning ahead puts you in a better position to manage your Medicare costs.
If you think your premiums are higher than they should be, or if you have experienced a life-changing event that reduced your income, it is worth exploring whether an appeal makes sense. And if you are still a few years from Medicare, planning ahead now can help you avoid surprises down the road.
