7 Ways Retirees Can Manage Income to Avoid Higher IRMAA 2026

The IRMAA Trap Most Retirees Don’t See Coming

Every January, I watch retirees open their Medicare premium notices and experience a jolt of sticker shock. Their income ticked just a few hundred dollars over a threshold they didn’t know existed, and suddenly their Medicare Part B and Part D premiums jumped by $1,000 or more per year. This is the Income-Related Monthly Adjustment Amount — IRMAA — and in my 18 years of financial planning practice, it remains one of the most misunderstood costs in retirement.

For 2025, roughly 7% of Medicare beneficiaries pay IRMAA surcharges, according to the Centers for Medicare & Medicaid Services. That’s about 4.4 million people. With new bracket adjustments arriving for 2026, the number could grow — especially as retirees contend with lingering inflation, required minimum distributions (RMDs), and Roth conversion decisions that can spike their modified adjusted gross income (MAGI) in a single tax year.

The good news: IRMAA is not a fixed punishment. It’s a planning opportunity. Below are seven concrete strategies I use with clients to help them manage income and avoid higher IRMAA brackets in 2026 and beyond.

1. Know the Exact IRMAA Brackets for 2026

You can’t dodge a line you can’t see. IRMAA brackets are based on your MAGI from two years prior — so your 2024 tax return (filed in 2025) determines your 2026 Medicare premiums. The Social Security Administration uses IRS data to make this determination automatically.

For 2025, the first IRMAA surcharge kicks in at a MAGI above $106,000 for single filers and $212,000 for married couples filing jointly. These thresholds are adjusted annually for inflation. Based on recent CPI-U trends, I’m estimating the 2026 single-filer threshold will land near $108,000–$110,000, though the official numbers won’t be published until fall 2025.

What counts as MAGI for IRMAA?

• Your adjusted gross income (AGI) from Form 1040, line 11
• Plus tax-exempt interest income (such as municipal bond interest)
• This means even “tax-free” muni bond income can push you into a higher IRMAA bracket

I often tell my clients: “IRMAA doesn’t care whether your income is taxable. It cares whether it exists.” That subtle distinction catches a surprising number of otherwise savvy retirees off guard.

2. Time Your Roth Conversions Strategically

Roth conversions are one of the most powerful tools in retirement tax planning. Converting traditional IRA funds to a Roth IRA means paying income tax now in exchange for tax-free growth and withdrawals later. But every dollar you convert counts as ordinary income in that tax year — and it counts toward your MAGI for IRMAA purposes.

What I see most often is retirees doing a large Roth conversion in a single year without realizing the IRMAA impact won’t hit until two years later. A $150,000 conversion in 2024, for example, could push a married couple well above the $212,000 threshold and trigger surcharges on both spouses’ Medicare premiums in 2026.

The smarter approach

• Spread conversions across multiple years, converting just enough to stay below the next IRMAA bracket
• Use the “gap years” between retirement and age 73 (when RMDs begin) when your income is naturally lower
• Run projections with your tax advisor every October, before year-end, to fine-tune the conversion amount

A well-timed series of smaller conversions can save tens of thousands of dollars in lifetime IRMAA surcharges while still achieving the Roth’s long-term tax benefits.

3. Coordinate RMDs to Minimize Income Spikes

Required minimum distributions from traditional IRAs, 401(k)s, and other tax-deferred accounts are a major IRMAA trigger. Under the SECURE 2.0 Act, RMDs now begin at age 73 (and will rise to 75 starting in 2033). Once they start, they’re mandatory and fully taxable.

Here’s a scenario I encountered just last quarter: a 74-year-old client with $1.2 million in a traditional IRA had an RMD of roughly $47,710. Combined with Social Security, a small pension, and capital gains from a mutual fund distribution, her MAGI landed at $113,000 — just enough to trigger the first IRMAA surcharge of $70.10 per month for Part B in 2025. That’s $841.20 in extra premiums she hadn’t budgeted for.

Tactics that help

• Consider Qualified Charitable Distributions (QCDs) — if you’re 70½ or older, you can direct up to $105,000 per year (2024 limit, indexed for inflation) from your IRA to a qualifying charity, and that amount is excluded from your AGI entirely
• If you have multiple retirement accounts, consolidate and plan withdrawals so RMDs don’t stack on top of other income sources in the same year
• Use tax-loss harvesting in brokerage accounts to offset capital gains that would otherwise inflate MAGI

QCDs are, in my professional opinion, the single most underused tool in IRMAA management. If you’re already giving to charity, there is almost no reason not to do it through a QCD.

4. Watch Out for One-Time Income Events

Life doesn’t always cooperate with tax planning. Selling a home, exercising stock options, receiving an inheritance from a tax-deferred account, cashing in a life insurance policy, or even settling a lawsuit — all of these can create one-time income spikes that push you into a higher IRMAA bracket two years later.

The IRMAA lookback is mechanical and unforgiving. The SSA doesn’t distinguish between a recurring salary and a one-time windfall. However, there is an appeals process.

The Life-Changing Event exemption

If your income was unusually high in the lookback year due to a qualifying life-changing event — such as the death of a spouse, divorce, loss of income-producing property, or cessation of work — you can file SSA-44 (Medicare Income-Related Monthly Adjustment Amount – Life-Changing Event) to request a reduction or elimination of the surcharge.

• Qualifying events include marriage, divorce, death of a spouse, work stoppage, work reduction, loss of income-producing property, and loss of pension
• A one-time capital gain from selling a vacation home does NOT qualify
• You must provide documentation such as a death certificate, signed statement from employer, or tax return

I keep SSA-44 forms pre-loaded in my client portal because, frankly, most people don’t even know this appeal exists.

5. Use the Right Accounts in the Right Order

The sequence in which you draw income from different accounts — what financial planners call “withdrawal sequencing” — has an enormous impact on your MAGI and, by extension, your IRMAA exposure.

Most retirees default to spending their taxable brokerage accounts first, then their tax-deferred accounts, and finally their Roth accounts. That textbook approach can backfire if it means you’re hit with large RMDs later in retirement when your traditional IRA has grown substantially.

A more IRMAA-aware sequencing strategy

• In your 60s (before RMDs begin): Lean into Roth conversions and spend from taxable accounts to keep traditional IRA balances from ballooning
• In your early 70s: Begin RMDs but supplement living expenses with Roth withdrawals (which don’t count toward MAGI) to stay below IRMAA thresholds
• Throughout retirement: Use Health Savings Account (HSA) funds for qualified medical expenses — these withdrawals are also excluded from MAGI

This kind of multi-account choreography is where a good financial plan pays for itself many times over. And it’s especially critical when inflation is quietly eroding purchasing power.

6. Don’t Ignore Tax-Exempt Interest Income

This one surprises even experienced investors. Municipal bond interest is generally exempt from federal income tax — that’s the whole point of munis. But for IRMAA purposes, tax-exempt interest is added back to your AGI to calculate MAGI. It’s right there on Form 1040, line 2a.

I had a client couple in 2023 with $85,000 in Social Security benefits, $40,000 from a pension, and $95,000 in municipal bond interest. Their federal tax liability was relatively modest. But their MAGI was $220,000, which put them $8,000 above the married-filing-jointly threshold and triggered a combined IRMAA surcharge of over $1,680 per year for both spouses.

What to consider

• If muni bond income is pushing you over an IRMAA threshold, evaluate whether taxable bonds in a tax-deferred account might actually produce a better after-cost result
• Consider shifting a portion of fixed-income holdings to Treasury I Bonds or TIPS inside an IRA, where the interest doesn’t appear on your 1040 at all
• Review your bond ladder annually — a maturing bond reinvested carelessly can change your income profile

The math isn’t always intuitive, but the principle is simple: the cheapest dollar in retirement is the one that doesn’t show up on your tax return.

7. Build an IRMAA Lookback Calendar and Review It Every Year

Because IRMAA operates on a two-year lookback, you need to think about your 2026 premiums right now — based on your 2024 income. And your 2027 premiums will depend on what you do in 2025. This rolling window means IRMAA planning is never a one-time event. It’s an annual discipline.

I recommend every retiree create or ask their advisor to create a simple lookback calendar:

• Tax Year 2024 → Determines 2026 IRMAA
• Tax Year 2025 → Determines 2027 IRMAA
• Tax Year 2026 → Determines 2028 IRMAA

Plot your expected income sources for each year, including Social Security, pensions, RMDs, investment gains, rental income, and any planned Roth conversions. Then compare each year’s projected MAGI against the current IRMAA brackets (adjusting upward by roughly 2–3% annually for inflation).

When to run the numbers

• October–November: Before year-end, when you can still adjust — sell losing investments, complete a QCD, or finalize a Roth conversion amount
• April: After filing your tax return, verify your MAGI and check whether it aligns with your IRMAA projections
• September–October of the following year: When SSA releases new IRMAA brackets, cross-reference against your filed return

This process takes about 30 minutes per review session. In my experience, it saves clients between $2,000 and $12,000 annually, depending on their income level and how many brackets they’re able to avoid.

The Bigger Picture: IRMAA, Inflation, and Your Retirement Security

Managing IRMAA isn’t just about saving a few hundred dollars a month on Medicare premiums — though that alone adds up to thousands over a retirement that could last 25 or 30 years. It’s about controlling the variables you can control in a financial landscape that increasingly feels like it’s working against retirees.

With the 2026 Social Security Trustees Report projecting that the Old-Age and Survivors Insurance trust fund could face depletion by the mid-2030s, and with inflation running above the Federal Reserve’s 2% target for much of the past three years, the margin for error in retirement planning is thinner than it has been in decades. According to a recent Investopedia analysis, nearly 45% of retirees report that inflation has forced them to withdraw more from savings than originally planned.

IRMAA surcharges compound that pressure. A retiree paying the highest IRMAA tier in 2025 faces Part B premiums of $594.00 per month — compared to the standard $185.00. That’s an extra $4,908 per year, per person. For a married couple both in the top bracket, the annual surcharge alone exceeds $9,800.

Those dollars are far better deployed toward healthcare, housing modifications for aging in place, or simply maintaining your quality of life. And with financial scams targeting seniors at record levels — older adults lost $4.8 billion to scams in 2024 — every dollar you protect through smart planning is a dollar a fraudster can’t take from you.

Start Your 2026 IRMAA Plan Now

If your 2024 tax return is already filed, pull it out and look at line 11 (adjusted gross income) and line 2a (tax-exempt interest). Add them together. Compare that number to the current IRMAA brackets. If you’re within $10,000–$15,000 of a threshold, you have planning work to do for 2025.

If you haven’t filed yet — or if you filed an extension — you still have time to make strategic decisions about estimated tax payments, charitable giving, and investment harvesting that can shape your 2027 IRMAA outcome.

In my practice, I’ve watched clients transform IRMAA from an annual frustration into a predictable, manageable expense. It requires attention, a calendar, and sometimes a willingness to do things in an unconventional order. But the payoff — potentially tens of thousands of dollars saved over a retirement — is worth every minute of planning.

The brackets are set. The lookback window is ticking. Your move.
