How to Beat IRMAA: The Income Game Most Retirees Are Losing

Your Medicare Part B premium is not just a flat number. If your income crossed certain thresholds two years ago, you're paying a surcharge called IRMAA (Income-Related Monthly Adjustment Amount) on top of the standard premium. The extra cost applies to both Part B and Part D, and it can add hundreds of dollars per month to your Medicare bill.

The frustrating part: most people don't find out about IRMAA until they get a letter from Social Security telling them they owe more. By then, the income that triggered it happened two years ago. But there are real strategies to fight back, plan ahead, and in some cases get the surcharge reduced or removed entirely.

We asked licensed Medicare agents across the country how they help clients deal with IRMAA. Their answers reveal specific, actionable tactics that go well beyond "make less money."

The 2-Year Lookback: Why 2024 Income Drives 2026 Premiums

IRMAA is always based on your Modified Adjusted Gross Income (MAGI) from two years prior. Your 2026 Medicare premiums are determined by what showed up on your 2024 tax return. Your 2027 premiums will be based on 2025 income.

This creates a timing trap. A one-time event in a single tax year, like selling a property, cashing out a 401(k), doing a large Roth conversion, or taking a distribution from an inherited IRA, can push you into a higher IRMAA bracket for the year that income is evaluated. Even if your income drops back to normal the following year, you'll still pay the higher premium until the lookback window catches up.

The IRMAA brackets for 2026 start at $109,000 for individuals and $218,000 for joint filers. Go even $1 over, and you jump to a higher premium tier. The surcharges are not gradual. They step up in brackets, which means a small income difference can mean a large premium increase. For the official premium and surcharge figures, Medicare.gov publishes the current-year cost tables.

Filing Status	2026 IRMAA Threshold (Lowest Tier)	What Happens Above It
Single	$109,000	Part B and Part D premiums increase on a sliding scale
Married Filing Jointly	$218,000	Same sliding scale, based on combined MAGI

Example: A single filer with 2024 MAGI of $108,999 pays the standard Part B premium in 2026. Bump that to $109,001 and they cross into the first surcharge tier, adding hundreds of dollars a year across Part B and Part D combined. Same person, $2 apart on their tax return — that's how sharp the step-up is.

This is why income planning in the years before and during Medicare enrollment matters so much. If you're 62 or 63 and considering a large financial move, know that the income from that move will show up on your Medicare premium bill at 64 or 65. For a deeper look at how all these costs add up, see what determines your Medicare costs and how to reduce them.

Form SSA-44: Your Best Weapon After a Life-Changing Event

If your income dropped because of a qualifying life event, you don't have to wait two years for IRMAA to adjust. Form SSA-44 lets you request that Social Security use your current (lower) income instead of the two-year-old tax return.

Qualifying life-changing events include:

• Retirement or reduction in work hours
• Death of a spouse
• Divorce or annulment
• Loss of income-producing property
• Loss of pension income
• Employer settlement or closure

One important detail: a one-time investment distribution or 401(k) withdrawal is not automatically a qualifying event by itself. However, if that withdrawal happened alongside retirement or work stoppage, you can tie them together on the form. The key is demonstrating that your income has genuinely decreased and the spike was temporary.

Timing matters with SSA-44. You generally file it after receiving your IRMAA determination notice from Social Security, though some agents recommend filing proactively once you have documentation of the income change. If approved, the lower premium can take effect relatively quickly. If you want guidance through the appeal process, here's how a Medicare advisor can help with IRMAA appeals.

Qualified Charitable Distributions: The Underused IRMAA Hack

If you're 70 and a half or older and have a traditional IRA, Qualified Charitable Distributions (QCDs) are one of the most effective tools for keeping your MAGI below IRMAA thresholds.

A QCD lets you transfer money directly from your IRA to a qualified charity. The distribution satisfies your Required Minimum Distribution (RMD) but does not count as taxable income. That's the key difference from taking the RMD yourself and then donating. With a QCD, the money never hits your adjusted gross income at all.

For someone already close to an IRMAA bracket, routing $10,000 or $20,000 of RMD money through QCDs can be the difference between the standard Part B premium and hundreds more per month.

The QCD cap is indexed to inflation and adjusts each year under the SECURE 2.0 Act, so check the current IRS limit before planning a large distribution. You can split donations across multiple charities. The donation must go directly from the IRA custodian to the charity. If the money touches your personal account first, it counts as income.

If you're already being charitable, restructuring those donations as QCDs costs you nothing extra while potentially saving thousands in Medicare premiums. It's a straightforward strategy that more retirees should know about. For other costs that catch people off guard, check out 5 hidden Medicare costs that blindside first-time enrollees.

Roth Conversion Timing: When the Math Works and When It Backfires

Roth conversions are a popular long-term tax strategy: move money from a traditional IRA to a Roth IRA, pay taxes on the conversion now, and enjoy tax-free withdrawals later. Since Roth withdrawals don't count toward MAGI, they can help you avoid IRMAA in future years.

But the conversion itself creates taxable income in the year you do it. That's where the backfire potential lives.

Convert $100,000 from a traditional IRA to a Roth at age 63, and that $100,000 shows up as income on your tax return. Two years later, at 65, Social Security uses that inflated income to set your Part B premium. You could end up paying IRMAA surcharges for a year or two because of a conversion meant to save you money long-term.

The math works best when you:

• Do conversions before age 63. This gives the lookback window time to clear before Medicare starts at 65.
• Spread conversions across multiple years. Instead of converting $200,000 in one year, convert $50,000 per year over four years to stay under IRMAA thresholds.
• Convert during low-income years. A year when you've just retired but haven't started Social Security or RMDs can be an ideal window.
• Run the numbers with a tax professional. The IRMAA brackets, your current tax bracket, and the projected growth of the Roth all factor into whether conversion makes sense now or later.

The bottom line on Roth conversions and IRMAA: they're not inherently good or bad. They require careful timing. A well-planned conversion strategy started 5 to 10 years before Medicare enrollment can save significant money. A poorly timed one can cost you more in the short run than it saves.

Other Tactics Agents Recommend

Spread Out Large Financial Events

Selling a vacation home, receiving a severance package, cashing out stock options: any of these can spike your MAGI in a single year. Where possible, spread these events across multiple tax years. Staying under the IRMAA threshold even by a dollar saves you the full surcharge for that bracket.

Coordinate Medicare and Tax Planning Together

Too many retirees plan their taxes and their Medicare separately. A financial advisor who understands IRMAA brackets can help you time withdrawals, conversions, and asset sales to avoid crossing income thresholds. This kind of coordinated planning is especially valuable in the two to three years before turning 65 and starting Medicare.

Use Tax-Free Income Sources Strategically

Roth IRA withdrawals and certain life insurance distributions generally don't count toward MAGI. Municipal bond interest is the big exception: even though it's tax-free for federal income tax, it gets added back into the MAGI figure Social Security uses for IRMAA. That's a detail that catches a lot of retirees off guard. Shifting more retirement income toward genuinely tax-free sources can help keep you below the brackets. Understanding how to lower your Part B premium after income drops is another piece of the puzzle.

Monitor Your Income Annually

IRMAA is recalculated every year. If you had one bad year but your income has returned to normal, the surcharge will drop once the lookback catches up. But don't assume Social Security will catch it automatically. Filing SSA-44 when you have a qualifying event, or at minimum reviewing your income situation each year with a professional who understands IRMAA, keeps you from overpaying.

Your IRMAA Action Checklist

Run through this before your next tax year closes:

• Pull last year's tax return and check your MAGI against the current thresholds.
• Flag any planned income events (home sale, Roth conversion, large withdrawal) for the next 2 to 3 years.
• If you had a qualifying life event, file SSA-44 with documentation instead of waiting out the lookback.
• If you're 70½ or older and give to charity anyway, send RMDs directly as QCDs.
• Open the IRMAA determination letter when it arrives. Don't stuff it in a drawer.
• Loop in both your tax advisor and a Medicare agent before any big year-end move.

The Real Cost of Not Planning

IRMAA surcharges at the highest bracket can add over $400 per month to your Part B premium alone, plus additional surcharges on Part D. For a married couple both on Medicare, that's potentially $10,000+ per year in extra premiums.

The retirees who avoid this are not necessarily lower-income. They're the ones who planned their income events around the IRMAA lookback window, used QCDs instead of standard RMD withdrawals, timed their Roth conversions strategically, and filed SSA-44 when life changes justified it.

IRMAA is not a penalty for being successful. It's a surcharge with rules, and those rules have built-in opportunities for people who understand them. Talk to a licensed Medicare agent and a tax professional together. The coordination between those two conversations is where the real savings happen.
