IRMAA Brackets 2026: A Medicare Income Playbook for Couples With $2M+ Saved

You budget for Medicare premiums. You probably don't budget for paying 2 to 3 times more than your neighbor for the same coverage.

That's what IRMAA does. If your income crosses certain thresholds, Medicare adds a surcharge to your Part B and Part D premiums.

For a married couple in the highest tier, the surcharges can total more than $13,800 per year.

In this guide, you'll see:

• What IRMAA is and why it hits couples with $2M+ saved harder than most
• The full 2026 IRMAA brackets for married couples filing jointly
• Five income strategies that may reduce or avoid IRMAA surcharges
• When you can appeal a surcharge and which life events qualify

Let's get into it.

What IRMAA Is and Why It Hits $2M+ Retirees Hardest

IRMAA stands for Income-Related Monthly Adjustment Amount. It's an additional Medicare premium paid by higher-income beneficiaries. It applies to both Part B and Part D.

The first surcharge starts when your MAGI exceeds $109,000 for individuals or $218,000 for married couples filing jointly. At the highest tier, IRMAA applies once MAGI reaches $500,000 for individuals or $750,000 for joint filers.

IRMAA is not a penalty. It's a pricing structure that increases Medicare premiums for higher-income beneficiaries.

If you have $2 million or more in 401(k)s and IRAs, your RMDs alone may push you into a higher IRMAA tier.

For couples with $2 million or more saved in tax-deferred accounts, required minimum distributions alone may push MAGI above the first threshold. A $150,000 RMD on top of Social Security and pension income can land you in the second or third tier.

The income that triggers IRMAA is the same income you're managing for Roth conversion timing, provisional income, and Social Security taxation. Treating IRMAA as a standalone Medicare issue misses the connection.

2026 IRMAA Brackets for Married Couples Filing Jointly

For 2026, Medicare uses your 2024 MAGI to determine whether IRMAA applies. The standard Part B premium is $202.90 per month before any surcharge.

MAGI includes your adjusted gross income plus tax-exempt interest. Here are the 2026 brackets for married couples filing jointly:

How IRMAA Uses Your Income From Two Years Ago

IRMAA looks back two years. Your 2026 surcharges are based on your 2024 tax return.

This two-year lag creates both a problem and an opportunity.

The problem: by the time you get the notice, the income year is already closed. You can't go back and change what you earned or withdrew in 2024.

The opportunity: if you're retiring before 65, the years between stopping work and starting Medicare are your lowest-income years. Those years may never appear on an IRMAA determination.

The years between retiring and claiming Medicare are the lowest-income years of your life. Use them.

This is where Roth conversions and strategic withdrawals come in. Converting during those gap years builds tax-free income in your Roth IRA. When Medicare pulls your MAGI two years later, qualified Roth distributions don't count.

You can read more about how Roth conversion timing affects your tax picture in this breakdown of why waiting to convert costs more than you think.

Five Ways to Manage Income and Reduce IRMAA Surcharges

You can't opt out of IRMAA. You can often influence the income that triggers it. Here are five strategies that may help.

1. Time Your Roth Conversions

Roth conversions increase your MAGI in the year you convert. But qualified Roth withdrawals don't count toward MAGI in later years.

The strategy: convert during low-income years, before Medicare starts or during years when other income is light. Build tax-free income so future years have less taxable income on the return.

If you convert too much in a single year, you may push yourself into a higher IRMAA tier. Spreading conversions across multiple years may keep MAGI below the next threshold.

2. Blend Withdrawals Across Tax Buckets

Most retirees with $2M+ saved have three account types: tax-deferred (401(k), IRA), tax-free (Roth), and taxable (brokerage). Each affects MAGI differently.

Traditional IRA and 401(k) withdrawals count fully toward MAGI. Roth withdrawals don't. Taxable account withdrawals only count the capital gains and dividends, not the principal.

Blending withdrawals across all three can keep MAGI below IRMAA thresholds while still meeting spending needs. For a deeper look at which accounts to spend first, see this withdrawal sequencing strategy.

3. Use Qualified Charitable Distributions

If you're 70½ or older, you can send money directly from your IRA to a qualified charity. That's a QCD.

QCDs satisfy your RMD requirement and don't count as taxable income. They reduce your MAGI, which may lower your IRMAA tier.

For couples who give to charity already, QCDs are one of the most direct ways to manage IRMAA. A $50,000 QCD that would have been a taxable distribution can drop you a full bracket.

4. Delay Social Security in Early Retirement

Social Security benefits count toward MAGI. If you delay benefits until 70, you're keeping MAGI lower during the years before you claim.

Those lower-income years are your best window for Roth conversions and for keeping IRMAA determinations low. For more on the claiming decision, see this comparison of claiming at 62 versus 70.

5. Spread Large Income Events Across Years

Selling a business, exercising stock options, or taking a large IRA withdrawal can spike MAGI in a single year. That spike may push you into the highest IRMAA tier.

Splitting these events across two or more tax years may keep you below a higher bracket. Timing matters: a sale in December creates income in one tax year. The same sale in January spreads it across two.

When You Can Appeal an IRMAA Surcharge

Certain life events qualify you to appeal your IRMAA determination using Form SSA-44. If your income has dropped because of one of these events, you may request that Medicare use your current income instead of your two-year-old tax return.

Qualifying events include:

• Retirement (stopping work or reducing hours)
• Marriage
• Divorce or annulment
• Death of a spouse
• Loss of income-producing property
• Loss of pension income
• Work stoppage or reduction

The appeal doesn't guarantee a reduction. It asks Social Security to recalculate based on a more recent estimate of your income.

Where IRMAA Fits in a Tax-First Retirement Plan

IRMAA is not a standalone problem. It connects to every other income decision in retirement: when you claim Social Security, when you do Roth conversions, how you sequence withdrawals, and when RMDs start.

Most advisors look at IRMAA as a Medicare issue. They hand you the bracket table and tell you where you land. For couples with $2 million or more saved, that approach misses the point.

IRMAA is a tax planning problem. The income that triggers it is the same income you're managing for Roth conversion timing, provisional income, and withdrawal sequencing. For more on how Social Security income interacts with your tax return, see this guide to provisional income.

A tax-first retirement plan looks at all of it together. Your claiming strategy, your conversion schedule, and your withdrawal sequencing all affect the MAGI that determines your Medicare costs.

If you want to see how your income sources interact and where your MAGI lands relative to the 2026 IRMAA brackets, a Retire Ready Roadmap can help you map it out. You can start that process here.
