Have questions on Medicare costs. Wondering about IRMAA Brackets and surcharges for your Medicare Parts B & D? We’re going to unpack the hidden expense that catches thousands of Medicare beneficiaries off guard every year. A surcharge that’s being determined by financial decisions you made back in 2024.
Picture this: You’ve just opened your 2026 Medicare statement, ready for another routine monthly premium. But instead of the expected $206.50, you’re staring at a bill for over $700. Your heart races.
What happened? Thousands of Medicare beneficiaries experience this same shock every year, blindsided by a surcharge they never saw coming.
The culprit? IRMAA, the Income-Related Monthly Adjustment Amount. And here’s the twist: the income decision that triggered this 2026 surcharge? You made it back in 2024, long before you ever thought about Medicare costs.
Welcome to the Medicare “time machine” where your financial past directly determines your healthcare future. But unlike sci-fi movies, there’s no going back to change history. What you can do is understand the rules, plan strategically, and potentially appeal if life threw you a curveball.
I’ll walk you through everything you need to know about IRMAA brackets and surcharges for Medicare Parts B and D, including the 2026 thresholds based on your 2024 income, how the system works, common income triggers that push retirees into higher brackets, and your safety net if circumstances have changed. Let’s get through this hidden Medicare expense together.
Key Takeaways Ahead
The IRMAA Problem: Why 2024 Income Determines 2026 Medicare Costs
That jaw-dropping figure on your 2026 Medicare statement? It’s likely the IRMAA (Income-Related Monthly Adjustment Amount) surcharge, a stealthy addition to your Part B and Part D premiums.
this unexpected cost isn’t based on your current earnings, but on your Modified Adjusted Gross Income (MAGI) from your 2024 federal tax return. It’s a financial ‘IRMAA time machine‘ that often leaves retirees wondering, ‘What just happened to my budget?’ This 2 year lookback mechanism catches thousands off guard annually.
The 2 year look back rule that creates a delayed connection between your income and your Medicare costs.
Here’s the three-step Original Medicare Premium IRMA timeline:
Think of IRMAA as a financial ‘time machine’ operating on a distinct three-year cycle. A system many other sources merely list without delving into its true implications. As you can see in the attached infographic, here is the tree steps of the IRMAA timeline:
- Step 1 (2024):
Back in 2024, your income was reported on your tax return, filed with the IRS in early 2025. - Step 2 (2025):
By late 2025, the IRS shared that 2024 MAGI data with the Social Security Administration (SSA). - Step 3 (2026):
Fast forward to 2026: the SSA weaponizes that two-year-old income data to set your current Medicare Part B and Part D premiums, often resulting in a retroactive hit. Not your Medicare Advantage Plan premiums. This is the year you’re actually paying the higher costs.
The specific figure the Social Security Administration examines isn’t your total income. It’s your Modified Adjusted Gross Income (MAGI).
My client, Frank, a retired teacher, learned this the hard way: a small bonus in 2024 led to an extra $1,200 annually on his 2026 Medicare bill. This isn’t just a timeline; it’s a delayed financial consequence that demands proactive strategies, a concept often missing in simpler explanations. Don’t let your financial past surprise your healthcare future.
🔍 Explained Simply: Your IRMAA Time Machine
The IRMAA system forces you to plan two years ahead. Your income reported on your 2024 taxes (filed in 2025) directly dictates your Medicare Part B and D costs for 2026. This disconnect is why proactive financial planning around retirement is absolutely critical.
How to understand what is MAGI for IRMAA?
Your Modified Adjusted Gross Income (MAGI) isn’t just your AGI. It’s your Adjusted Gross Income (AGI) from line 11 of your tax return, plus certain typically non-taxable deductions like tax-exempt interest from municipal bonds. This distinction is crucial, yet often overlooked.
What stealthy financial moves unexpectedly catapult retirees into higher IRMAA brackets?
In my near three decades advising clients, I’ve seen that it’s rarely steady paychecks; instead, it’s frequently those ‘one-time’ financial transitions people make when nearing or entering retirement, decisions that seem prudent at the time but carry unseen Medicare penalties. The IRS’s definition of MAGI for IRMAA is deceptively simple, but its impact is anything but.
Watch this quick YouTube video I put together that summarizes this article. Just press play:
💡 Michael Ryan Money Tip: Calculating Your MAGI for IRMAA
To pinpoint your exact MAGI for IRMAA purposes, start with your Adjusted Gross Income (AGI) from line 11 of your 2024 federal tax return. Then, add back any tax-exempt interest (e.g., from municipal bonds). That final number is what the SSA will use. Example: If your AGI was $95,000 and you had $5,000 in tax-exempt bond interest, your MAGI for IRMAA is $100,000. Simple, right? But missing that $5,000 can cost you!
Common Income Events That Trigger IRMAA
What types of financial moves accidentally push retirees over IRMAA thresholds? Often, it’s the significant financial transitions people make around retirement:
- Capital gains from asset sales: Selling investment property, a second home, or substantial stock positions creates large one-time gains that spike your MAGI. Unlike regular income, these are often large, one-time spikes that are difficult to mitigate once realized, catching many off guard.
- Roth IRA conversions: Converting a traditional IRA or 401(k) to a Roth IRA counts as taxable income in the conversion year, directly increasing your MAGI. This is a powerful tool for future tax-free growth but requires precise timing to avoid IRMAA.
- Large retirement account withdrawals: Taking significant distributions from your 401(k), 403(b), or Thrift Savings Plan for major purchases (e.g., a new home, gifting to family) can unexpectedly push you into a higher bracket.
- Federal employee leave payouts: Federal workers receiving payment for accumulated unused annual leave at retirement can see a substantial, unexpected MAGI increase in that retirement year.
- Pension lump-sum elections: Choosing a lump-sum pension payout rather than monthly payments concentrates taxable income, making IRMAA a very real risk.
- Business sales: Selling a business or practice creates substantial capital gains, often the largest single income event for many retirees, with huge IRMAA implications.
⚠️ Myth Busted: “Only the Rich Pay IRMAA”
Many believe IRMAA only impacts the “super-rich.” This is a dangerous myth! Even middle-income retirees can trigger IRMAA with a one-time income spike like a Roth conversion or selling a rental property. Crossing a threshold by just $1 makes you pay the full surcharge.
2026 IRMAA Brackets and Medicare Part B Premiums
The 2026 standard Medicare Part B premium is projected to be approximately $206.50 per month. High-income beneficiaries must pay this standard premium plus an IRMAA surcharge, with the highest bracket reaching approximately $702 per month based on 2024 MAGI.
Let’s examine the actual numbers for 2026. Understanding these brackets is essential for both current payment planning and future income management.
The Standard Medicare Part B Premium for 2026
The standard Medicare Part B premium for 2026 is projected at approximately $206.50 per month. This baseline amount applies to all Medicare beneficiaries whose earnings fall below the first IRMAA threshold.
2026 IRMAA Brackets and Surcharge Amounts (Based on 2024 MAGI)
The income-related monthly adjustment amount IRMAA brackets 2026 operate on a progressive scale with six income brackets. The table below shows the thresholds and costs for married couples filing jointly and the corresponding monthly premium.
| Bracket | Married Filing Jointly MAGI (2024) | Monthly Part B Premium (2026) (Per Person) | Monthly Part D IRMAA (2026) (Per Person) |

| 6 (Highest) | Above $750,000 | Approx. $702 | $91.00 |
📊 Quick Stat: The $1 Cliff’s Cost
Crossing an IRMAA bracket by just $1 can cost you over $900 per person annually in extra Medicare Part B and D premiums. This isn’t prorated! If you’re married, that’s over $1,800 annually for your household for that tiny income increase.

The Life-Changing Event Appeal: Your Safety Net
If your income has dropped significantly since 2024 due to a major life event, you can file a Life-Changing Event Appeal using Form SSA-44 with the Social Security Administration (SSA) to request that your 2026 Medicare premiums be based on your new, lower current income.
What if circumstances beyond your control have reduced your income since 2024? Are you stuck paying higher premiums based on income you’re no longer earning?
Fortunately, no. The Social Security Administration provides a critical safety valve called the life-changing event appeal.
💡 Michael Ryan Money Tip: The SSA-44 Lifeline
I’ve helped clients successfully navigate the SSA-44 process, particularly when documentation for a work stoppage or divorce was initially unclear. Don’t be intimidated; if you have a qualifying event, this form is your pathway to potentially saving thousands. It’s a key tool in your financial arsenal.
Qualifying Life-Changing Events
The Centers for Medicare and Medicaid Services recognizes several major life events that can significantly reduce your income:
- Work stoppage or reduction: Retirement from your primary job, being laid off, or reducing work hours.
- Marriage: Getting married can change your income situation, potentially impacting your joint MAGI.
- Divorce or annulment: Separation of assets and income streams drastically alters individual MAGI.
- Death of spouse: Loss of a spouse’s income often reduces household MAGI.
- Loss of income-producing property: Loss due to disaster, bankruptcy, or other circumstances beyond your control (e.g., a rental property destroyed).
- Loss of pension income: Cessation of pension payments through no fault of your own (e.g., plan termination).
- Employer settlement payment: Certain one-time employer settlement payments that affected a prior year’s income may be appealed if they are truly non-recurring.
The tool you need for this process is Form SSA-44, officially titled “Medicare Income-Related Monthly Adjustment Amount – Life-Changing Event.”
🛠️ How to File Your Appeal: Filing the appeal correctly is essential to get your premium reduced quickly.

A Real Client Example: When Good Tax Planning Meets Bad Medicare Math
Tom and Susan walked into my office holding an SSA letter. Their question was simple: “How does a $25,000 Roth conversion cost us $2,100 every year in Medicare premiums?”
This client story perfectly illustrates the paradox where seemingly good tax planning can have profoundly bad Medicare math.
Here’s the thing: if they’d split that conversion into two years ($12,500 in 2022 and $12,500 in 2024, or better yet, carefully managed 2024 and 2025 conversions) they’d have stayed under the threshold both years and paid zero IRMAA. Same long-term tax benefit, $2,100 less in annual Medicare costs.
Why didn’t this happen? Because their tax advisor wasn’t thinking two years ahead to Medicare. And Tom and Susan didn’t know IRMAA existed until the damage was done. Cross an IRMAA bracket by $1, and you pay the full annual surcharge. There’s no proration. No partial credit. Just a binary choice: under the line or over it. T
om and Susan’s conversion made sense. The timing didn’t. Will you be another Tom and Susan, or will you plan ahead?

💡 Michael Ryan Money Tip: Medicare Advantage & IRMAA
If you’re on a Medicare Advantage (Part C) plan, you still pay your standard Part B premium. This means IRMAA can absolutely still impact your Part B costs, even if your Part C plan premium itself isn’t directly adjusted. Don’t assume an MA plan shields you completely from IRMAA!
Final Thoughts: Taking Control of Your Medicare Costs
The two-year IRMAA look-back can feel like a trap, a delayed consequence that catches you off guard.
But reframe it as a two-year planning window, and you gain tremendous control over your Medicare Part B and Part D premiums.
Your 2024 income is now history, setting your 2026 Medicare costs. This means your primary action for 2026 is determining if you qualify for the life changing event appeal. But remember, your 2025 income, which you’re earning and reporting right now, determines your 2027 premiums.
The real question is whether you’ll be surprised by IRMAA or whether you’ll plan for it proactively. Consult with financial and tax professionals who understand IRMAA implications. Your future self will thank you for paying attention to IRMAA brackets and surcharges for parts B and D today.
