How Retirees Can Manage Income to Avoid Higher IRMAA 2026

The Hidden Medicare Tax Most Retirees Don’t See Coming

Every year, I watch clients walk into my office stunned by a letter from Social Security telling them their Medicare premiums just jumped by hundreds of dollars. They didn’t change their coverage. They didn’t miss a payment. They simply had too much income two years ago—and now they’re paying for it through something called IRMAA.

IRMAA stands for Income-Related Monthly Adjustment Amount, and it’s essentially a surcharge on top of your standard Medicare Part B and Part D premiums. In my 20 years of experience as a CPA and Enrolled Agent, I can tell you this: IRMAA is one of the most overlooked costs in retirement planning, and it catches people off guard precisely because of its two-year delay.

The good news? With the right strategies, you can manage your income to avoid higher IRMAA brackets in 2026 and beyond. This guide walks you through exactly how to do it, step by step.

How IRMAA Actually Works: The Two-Year Lookback

Here’s the mechanism that trips up most retirees. Medicare doesn’t look at your current year’s income to set your premium. Instead, it uses your Modified Adjusted Gross Income (MAGI) from two years prior. So your 2026 Medicare premiums are based on your 2024 tax return. Your 2027 premiums? Those are locked in by what you earn in 2025.

This means the income planning you do right now directly affects what you’ll pay in Medicare surcharges next year and the year after. It’s a lagging system, and if you’re not thinking ahead, you’ll always be reacting instead of planning.

What Counts as MAGI for IRMAA?

Your MAGI for IRMAA purposes includes your Adjusted Gross Income (AGI) plus tax-exempt interest income. That means the following all count:

• Traditional IRA and 401(k) distributions
• Social Security benefits (the taxable portion)
• Capital gains from selling stocks, mutual funds, or property
• Rental income
• Pension payments
• Tax-exempt municipal bond interest (yes, even this)
• Part-time employment or consulting income

What I see most often is a retiree who sells a rental property or cashes out a large IRA balance in a single year, not realizing that one-time spike will push them into a higher IRMAA bracket two years later. By then, it’s too late to undo.

2026 IRMAA Brackets: Know Your Numbers

The Social Security Administration adjusts IRMAA thresholds annually based on inflation. While final 2026 brackets are confirmed each fall, the projected thresholds based on recent CPI data give us a reliable planning framework. Here’s what retirees need to prepare for:

Filing Status: Single	Filing Status: Married Filing Jointly	Monthly Part B Surcharge (2026 Est.)	Monthly Part D Surcharge (2026 Est.)	Total Annual Extra Cost Per Person
$106,000 or less	$212,000 or less	$0 (standard premium)	$0	$0
$106,001–$133,000	$212,001–$266,000	+$70.00	+$13.00	$996
$133,001–$167,000	$266,001–$334,000	+$175.00	+$33.00	$2,496
$167,001–$200,000	$334,001–$400,000	+$280.00	+$54.00	$4,008
$200,001–$500,000	$400,001–$750,000	+$384.00	+$74.00	$5,496
Above $500,000	Above $750,000	+$419.00	+$81.00	$6,000

“For a married couple both on Medicare, crossing just one IRMAA bracket can cost an additional $2,000 to $5,000 per year in premiums alone. That’s money that comes straight out of your retirement savings—and it’s entirely avoidable with proper planning.”

Take a close look at where your income lands relative to these thresholds. If you’re within $5,000 to $10,000 of a bracket boundary, you have a real opportunity to make strategic adjustments that keep you in the lower tier.

7 Steps to Manage Your Income and Avoid Higher IRMAA Brackets

I often tell my clients that IRMAA planning isn’t about earning less money—it’s about being smarter with the timing and character of your income. Here’s my proven playbook:

1. Map your two-year income timeline.

   Pull up your 2024 tax return right now. That’s what determines your 2026 IRMAA bracket. Then project your 2025 income, because that sets your 2027 bracket. Create a simple spreadsheet with every income source—IRA distributions, Social Security, pensions, capital gains, rental income, and interest. Knowing your baseline number is the essential first step. If you’re not sure where you stand, the IRS Free File system and your most recent Form 1040 are your starting points.

2. Execute strategic Roth conversions before crossing a bracket.

   If your income is well below an IRMAA threshold, consider converting a portion of your traditional IRA to a Roth IRA—but only up to the point that keeps you under the next bracket. For example, if you’re a married couple filing jointly with a MAGI of $190,000, you could convert up to roughly $22,000 to a Roth without triggering the first IRMAA surcharge. The Roth conversion itself is taxable income, but once funds are in a Roth, future withdrawals are tax-free and don’t count toward MAGI. Over five to ten years, this strategy can dramatically reduce your IRMAA exposure.

3. Harvest capital gains in low-income years.

   If you’re planning to sell appreciated investments—stocks, mutual funds, real estate—time the sale for a year when your other income is naturally lower. Did you just retire mid-year and have only six months of pension income? That might be the perfect year to realize gains. Spreading sales across multiple tax years instead of dumping everything in one year is one of the most effective IRMAA reduction tactics I use with clients.

4. Use Qualified Charitable Distributions (QCDs) from your IRA.

   If you’re 70½ or older, you can direct up to $105,000 per year (2024 limit, indexed to inflation) from your traditional IRA directly to a qualified charity. The beauty of a QCD is that it satisfies your Required Minimum Distribution but does not count as taxable income on your return. That means it doesn’t inflate your MAGI. For a retiree who donates to their church, alma mater, or community organization, this is one of the most powerful IRMAA tools available. I’ve seen clients save $1,500 to $3,000 a year in IRMAA surcharges with this single strategy.

5. Defer or stagger large distributions.

   Need $80,000 from your IRA for a home renovation or a new car? Don’t pull it all in December. If possible, split it across two calendar years—$40,000 in late December and $40,000 in early January. Each year carries a lower income figure, which may keep you below an IRMAA threshold in both lookback periods. This requires planning ahead, but the savings can be substantial. For more strategies on protecting your nest egg, see my earlier piece on Inflation Draining Retirement Savings: A CPA’s Survival Guide.

6. Consider the timing of Social Security benefits.

   While Social Security income itself can push you into higher IRMAA territory (up to 85% of benefits are taxable for higher earners), the decision of when to claim affects your overall MAGI trajectory. Delaying Social Security to age 70 means higher monthly payments later, but it also means lower total income in the years between retirement and age 70—which can create a window for Roth conversions and capital gains harvesting at lower brackets. It’s a balancing act, and I walk clients through the math every single time.

7. File an IRMAA appeal if you qualify.

   This is the step most people don’t know about. If your income dropped significantly due to a “life-changing event”—retirement, reduction in work hours, death of a spouse, divorce, or loss of income-producing property—you can file Form SSA-44 with Social Security to request that they use your current year’s income instead of the two-year-old figure. I’ve helped clients save $3,000 to $5,000 in a single year with a successful appeal. The key is having documentation ready: a letter from your employer confirming retirement, a death certificate, or proof of property loss.

“IRMAA planning is really income choreography. You’re not reducing what you earn over a lifetime—you’re controlling when and how it shows up on your tax return. That timing difference can save tens of thousands of dollars across retirement.”

Common Mistakes That Push Retirees Into Higher IRMAA Brackets

In my practice, I see the same costly errors repeated year after year. Here are the ones that hurt the most:

Mistake #1: Ignoring Municipal Bond Interest

Many retirees invest in municipal bonds because the interest is federal-tax-free. That’s true for income tax purposes. But here’s the catch: tax-exempt interest is added back into your MAGI for IRMAA calculations. I’ve seen clients with $30,000 or more in muni bond interest who had no idea it was pushing them over a bracket threshold. If you hold munis, factor that interest into your IRMAA projections.

Mistake #2: Taking a Lump-Sum Pension Distribution

When offered the choice between a lump sum and an annuity from a pension plan, some retirees grab the lump sum without considering the IRMAA impact. A $200,000 lump-sum rollover to an IRA might not trigger immediate tax if done as a direct rollover, but a lump-sum cash distribution is fully taxable and can catapult your MAGI into the highest IRMAA tier for two years.

Mistake #3: Selling a Home Without Planning

The $250,000 single / $500,000 married capital gains exclusion on a primary residence is generous. But if your gain exceeds those limits—or if you’re selling a second home or investment property with no exclusion—the resulting capital gain flows directly into your MAGI. I always tell clients to model the IRMAA impact before listing the property. Sometimes waiting one year to sell makes a five-figure difference in total costs. If you’re considering home modifications instead of selling, check out this guide on Aging in Place: Why Most Homes Aren’t Ready and How to Fix Yours.

Mistake #4: Forgetting About Required Minimum Distributions (RMDs)

Starting at age 73 (under the SECURE 2.0 Act), you must take RMDs from traditional IRAs and most employer plans. These distributions are fully taxable and count toward MAGI. If you haven’t been doing Roth conversions in your 60s to reduce your traditional IRA balance, you may face RMDs large enough to trigger IRMAA surcharges every year for the rest of your life. This is why early planning matters so much.

How IRMAA Interacts With Other Retirement Costs

IRMAA doesn’t exist in a vacuum. Higher income also affects how much of your Social Security is taxable (up to 85% of benefits for individuals with combined income above $34,000), your eligibility for certain tax credits, and even the net investment income tax (3.8% on investment income above $200,000 single / $250,000 married).

When I build a retirement income plan for clients, I’m looking at the total marginal cost of each additional dollar of income. Sometimes that marginal cost—federal tax, state tax, IRMAA surcharge, Social Security taxation, and NIIT—can approach 50% or more. That’s why income management isn’t optional; it’s one of the most important financial decisions a retiree makes every year.

A Real-World Example: How One Couple Saved $3,984 in IRMAA

Let me share a simplified version of a scenario I’ve worked through with clients. Tom and Linda are both 68, married filing jointly, and both enrolled in Medicare Part B and Part D. Their projected 2025 income looks like this:

• Pension income: $52,000
• Social Security (combined): $48,000
• Traditional IRA distribution: $65,000
• Municipal bond interest: $12,000
• Capital gains from mutual fund sales: $30,000

Their projected MAGI (including 85% of Social Security taxability and muni interest) comes to approximately $277,000. That puts them in the second IRMAA bracket for married couples ($212,001–$266,000—actually, they’re above it, landing in the third bracket at $266,001–$334,000).

At the third bracket, each of them pays an estimated $175 + $33 = $208 per month in IRMAA surcharges. For both of them, that’s $416/month, or $4,992 per year.

Here’s what we did: We reduced the IRA distribution from $65,000 to $40,000 (they had sufficient cash reserves to cover the gap). We also directed $15,000 of the IRA withdrawal as a QCD to their church, which removed it from MAGI entirely. Finally, we deferred $20,000 of the mutual fund sales to January 2026.

The result? Their revised MAGI dropped to approximately $222,000—just inside the first IRMAA bracket. Their combined IRMAA surcharge fell to $83/month each, or $1,992/year total. That’s a savings of $3,000 per year, and they still met all their spending needs.

When to Start IRMAA Planning

The best time to start is at least two to three years before you enroll in Medicare (so around age 62–63 if you plan to enroll at 65). The second best time is right now. Because of the two-year lookback, every income decision you make today echoes forward.

I recommend reviewing your IRMAA exposure every October and November, before year-end, when you still have time to make Roth conversions, take QCDs, harvest or defer gains, and adjust IRA distributions. Work with a CPA or tax advisor who understands the interplay between Medicare, Social Security, and tax planning. According to Investopedia, IRMAA affects roughly 7% of Medicare beneficiaries—but among retirees with pensions, investments, and real estate, the percentage is significantly higher.

Your IRMAA Action Checklist for 2026

Here’s a quick-reference checklist to keep handy as you plan:

• ☐ Review your 2024 tax return—this sets your 2026 IRMAA bracket
• ☐ Project your 2025 income by source—this sets your 2027 bracket
• ☐ Identify whether you’re within $10,000 of a bracket boundary
• ☐ Model Roth conversion amounts that stay below the next threshold
• ☐ Set up QCDs for charitable giving if you’re 70½+
• ☐ Stagger any large asset sales across tax years
• ☐ File Form SSA-44 if you experienced a qualifying life-changing event
• ☐ Schedule a year-end tax planning meeting with your CPA by October

Final Thoughts From a CPA Who’s Seen It All

Managing income to avoid higher IRMAA brackets in 2026 isn’t about gaming the system. It’s about being intentional with the money you’ve spent a lifetime earning. The rules are complex, the thresholds shift, and the two-year lookback creates a planning horizon that most retirees aren’t accustomed to thinking about.

But I’ve watched clients save $3,000, $5,000, even $8,000 a year just by paying attention to when and how they take income. That’s real money—money that stays in your retirement accounts, funds your grandchildren’s education, or simply gives you more breathing room.

You worked hard to build your savings. Don’t let a surcharge you never saw coming erode it year after year. Start planning today, and you’ll thank yourself in 2026 and every year after.
