How to Manage Retirement Income to Avoid Higher Medicare IRMAA

The Surprise Premium Hike Nobody Warns You About

You’ve saved diligently, filed for Social Security at what you believed was the optimal age, and started drawing from your retirement accounts. Then a letter arrives from Medicare informing you that your Part B premium isn’t the standard $185 per month everyone else pays — it’s $259.40, or $370.40, or worse. Welcome to IRMAA, the Income-Related Monthly Adjustment Amount, and in my 18 years of financial planning, it remains the most consistently overlooked cost in retirement.

IRMAA isn’t a tax. It’s a surcharge applied to both Medicare Part B and Part D premiums when your modified adjusted gross income (MAGI) exceeds certain thresholds. For 2026, those thresholds are based on your 2024 tax return — meaning income decisions you made last year are already determining what you’ll pay next year. And because the brackets aren’t indexed generously to inflation, more retirees are crossing into higher tiers every single year.

This guide walks you through exactly how IRMAA works, who’s at risk, and the concrete steps you can take to manage retirement income and keep your Medicare premiums as low as legally possible.

Understanding How IRMAA Is Calculated

What Counts as MAGI for Medicare?

Medicare uses a specific version of modified adjusted gross income that includes your adjusted gross income (line 11 on your Form 1040) plus any tax-exempt interest income (line 2a). That means municipal bond interest — which many retirees hold specifically for tax efficiency — still counts toward IRMAA thresholds even though it’s not subject to federal income tax.

Here’s what feeds into your MAGI for IRMAA purposes:

• Social Security benefits (the taxable portion)
• Traditional IRA and 401(k) distributions
• Pension income
• Capital gains from investment sales
• Rental income
• Tax-exempt interest (municipal bonds)
• Roth conversions (the full converted amount)
• Required Minimum Distributions (RMDs)

What I see most often is a retiree who triggers a higher IRMAA bracket with a single large event — selling a rental property, taking a lump-sum pension distribution, or doing an oversized Roth conversion — without realizing the Medicare cost impact until two years later.

2026 IRMAA Brackets: Know Where You Stand

The Social Security Administration publishes updated IRMAA brackets annually. Below are the 2026 Part B premium tiers based on 2024 MAGI (the most recent figures available as of this writing):

2024 MAGI (Individual)	2024 MAGI (Married Filing Jointly)	2026 Monthly Part B Premium	Additional Monthly Cost vs. Standard
$106,000 or less	$212,000 or less	$185.00	$0 (standard)
$106,001–$133,500	$212,001–$267,000	$259.40	+$74.40
$133,501–$167,000	$267,001–$334,000	$370.40	+$185.40
$167,001–$200,000	$334,001–$400,000	$481.40	+$296.40
$200,001–$500,000	$400,001–$750,000	$592.40	+$407.40
Above $500,000	Above $750,000	$628.90	+$443.90

For a married couple both on Medicare, even jumping one bracket means an extra $1,785.60 per year — money that comes straight out of your retirement income with zero additional benefit. Part D surcharges add even more on top.

“IRMAA is a stealth retirement tax. For a couple that crosses into the third bracket, the combined Part B and Part D surcharges can exceed $6,000 annually — and most people don’t learn about it until the bill arrives.”

Step-by-Step Strategies to Manage Retirement Income and Avoid IRMAA

Map Your Two-Year Look-Back Window

Because Medicare uses income from two years prior, you need to plan in advance. If you’re turning 65 in 2027, your 2025 income determines your initial premiums. I tell my clients to think of it as a “two-year income runway” — every financial decision you make today has Medicare cost implications 24 months from now.

Start by pulling your most recent tax return and identifying exactly where your MAGI falls relative to the brackets above. If you’re within $5,000–$10,000 of the next threshold, you have both a risk and an opportunity.

Smooth Out Roth Conversions Over Multiple Years

Roth conversions are one of the most powerful tools in retirement tax planning, but a poorly timed conversion can spike your MAGI and trigger IRMAA. Instead of converting $150,000 in a single year, consider converting $40,000–$50,000 annually over three to four years, staying just below the next IRMAA bracket each time.

I often tell my clients that the “sweet spot” for Roth conversions is the gap between your current income and the next IRMAA threshold. Fill that gap — don’t overflow it.

Time Capital Gains and Large Asset Sales Strategically

Selling a home, liquidating a concentrated stock position, or disposing of a rental property can generate a one-time income spike that pushes you into a higher bracket. When possible, spread gains across two tax years using installment sales, or offset gains with harvested tax losses from other positions.

If you’ve already realized a large gain in 2025, consider deferring other discretionary income — like an IRA distribution you don’t actually need for living expenses — into 2026 instead.

Use Qualified Charitable Distributions (QCDs) After Age 70½

Once you turn 70½, you can direct up to $105,000 per year (2024 limit, indexed for inflation) from your traditional IRA directly to a qualified charity via a Qualified Charitable Distribution. The beauty of a QCD is that it satisfies your Required Minimum Distribution but does not count as taxable income — meaning it doesn’t inflate your MAGI for IRMAA purposes.

For retirees who already donate to charity, this is one of the most effective IRMAA-avoidance tools available. The IRS provides detailed guidance on QCD eligibility and reporting requirements.

Consider the Timing of Social Security Benefits

Up to 85% of your Social Security benefits become taxable income when your combined income exceeds $44,000 (married filing jointly). If you’re still working part-time or have significant investment income, delaying Social Security can keep your MAGI lower in the years before you claim — reducing IRMAA exposure during those critical early Medicare years.

Leverage Health Savings Account (HSA) Distributions

If you contributed to an HSA while still working, those funds can be withdrawn tax-free in retirement for qualified medical expenses — including Medicare premiums themselves. Because HSA distributions for medical expenses don’t appear as taxable income, they don’t count toward MAGI. This is an often-overlooked source of “invisible” retirement income.

What to Do If You’ve Already Been Hit with IRMAA

File an Appeal Using the Life-Changing Event Exception

If your income spiked due to a one-time event or you’ve experienced a qualifying life-changing event since the tax year Medicare is using, you can file SSA-44 (Medicare Income-Related Monthly Adjustment Amount — Life-Changing Event) with Social Security. Qualifying events include:

• Marriage, divorce, or death of a spouse
• Work stoppage or reduction
• Loss of income-producing property (involuntary)
• Loss of pension income
• Employer settlement or bankruptcy

I’ve helped clients successfully appeal IRMAA determinations multiple times. The key is providing documentation — a letter from a former employer, a divorce decree, or proof of property loss — along with an estimate of your current-year income showing it’s substantially lower.

Adjust Withholding and Estimated Payments Proactively

If you’re already in a higher IRMAA bracket for 2026, focus your energy on managing your 2025 income to bring down 2027 premiums. Review your estimated tax payments, adjust withholding on pension income, and consider whether planned distributions or asset sales can be deferred or restructured.

“The retirees who pay the lowest Medicare premiums aren’t necessarily the ones with the least wealth — they’re the ones who plan their income two years ahead. IRMAA rewards foresight.”

The Bigger Picture: IRMAA in the Context of 2026 Retirement Planning

IRMAA doesn’t exist in isolation. With inflation eroding purchasing power, many retirees are drawing down savings faster than projected — a trend I’ve written about extensively. If you’re feeling the squeeze, Retirees Depleting Savings Faster: A CFP’s 2026 Survival Guide covers the broader withdrawal-rate strategies that complement the IRMAA playbook.

Meanwhile, Medicare Advantage enrollment continues to evolve in 2026, with significant plan changes in benefit structures and out-of-pocket maximums. Whether you’re in Original Medicare or an Advantage plan, IRMAA surcharges apply to your Part B and Part D premiums regardless.

Don’t Let IRMAA Paralyze Good Financial Decisions

I want to be clear about something: avoiding IRMAA should never be your only goal. Sometimes it makes perfect financial sense to do a large Roth conversion, sell an appreciated asset, or take a lump-sum distribution — even if it temporarily increases your Medicare premiums. The key is making that decision deliberately, with full knowledge of the cost, rather than being blindsided.

A $5,000 IRMAA surcharge is painful, but it might be worth it if the Roth conversion saves you $25,000 in future taxes. The math matters, and it’s almost always worth running the numbers — or working with a Certified Financial Planner who specializes in retirement income — before making large financial moves.

Your IRMAA Action Checklist for Right Now

• Pull your 2024 tax return and calculate your exact MAGI. Compare it to the bracket table above.
• Project your 2025 income — this determines your 2027 Medicare premiums. Identify any controllable income sources.
• Review upcoming Roth conversion plans. Can you spread them over multiple years to stay below the next IRMAA tier?
• Check if you’re eligible for QCDs. If you’re 70½+ and making charitable donations from after-tax money, you’re leaving MAGI reduction on the table.
• Set a calendar reminder for October to review your income trajectory before year-end, when you still have time to adjust.
• File SSA-44 immediately if you’ve experienced a qualifying life-changing event and are currently paying a higher IRMAA surcharge.

Managing retirement income to avoid higher Medicare IRMAA premiums isn’t about tricks or loopholes. It’s about awareness, planning, and making income timing decisions with the full picture in front of you. The two-year look-back window gives you a genuine opportunity to control your costs — but only if you use it proactively. Start today, review your numbers, and give your future self a Medicare bill that doesn’t sting.
