What Is IRMAA and Why It Matters in Retirement
IRMAA stands for Income-Related Monthly Adjustment Amount, a surcharge added to your Medicare Part B and Part D premiums when your income exceeds certain thresholds. These penalties can add thousands of dollars annually to your healthcare costs.
The core problem: Medicare uses a two-year look-back period. Income you reported two years ago directly affects your premiums today. A major IRA withdrawal, Roth conversion, or asset sale in 2024 triggers IRMAA surcharges throughout 2026 and beyond. Most retirees don't realize this connection until the bill arrives.
A single retiree with Modified Adjusted Gross Income (MAGI) above $97,000 in 2024 pays surcharges in 2026. Married couples filing jointly hit surcharges at $194,000. These thresholds create the "IRMAA cliff", a sharp cost increase once crossed. The difference between staying just below and just above a threshold can mean an extra $100 to $200 monthly in Medicare premiums.
The good news: avoiding IRMAA surcharges isn't about luck, it's about strategy. Timing your income, managing withdrawals, and understanding look-back rules can save tens of thousands over your retirement years.
How IRMAA Is Calculated and the Role of MAGI
Your IRMAA surcharge is calculated using Modified Adjusted Gross Income (MAGI) from two years prior. The Social Security Administration compares your MAGI to income brackets and assigns a surcharge tier.
MAGI for Medicare purposes includes:
- Wages, salary, interest, and dividends
- Capital gains (long-term and short-term)
- Distributions from traditional IRAs and 401(k)s
- Taxable Social Security benefits
- Rental income and business income
- Roth conversion amounts (the full converted amount counts as income)
What's NOT included: qualified charitable distributions, return-of-basis amounts on non-qualified annuities, and certain exclusions. This is where strategy comes in.
The two-year look-back means your 2026 premiums are based on your 2024 tax return. You cannot retroactively undo a surcharge, but you can appeal it if a life-changing event occurred using Form SSA-44.
2026 Medicare IRMAA Brackets and Premium Thresholds
For 2026, single filers begin paying surcharges at $97,000 MAGI. Married couples filing jointly start at $194,000. The surcharge increases at each bracket, with the highest earners paying significantly more.
These thresholds matter because earning $1 more than the threshold can push you into a higher surcharge tier, costing hundreds of dollars more annually. This is why precision in income planning is essential.
The brackets apply to both Part B and Part D using the same MAGI calculation. You might pay surcharges on both or on one but not the other, depending on your income level.
For pre-retirees and early retirees, the brackets create a planning window. If you're approaching retirement, you have time to structure your income to stay below surcharge thresholds. If you're already retired, you can adjust your withdrawal strategy to manage your MAGI in future years.
Impact of Roth Conversions on Medicare Premiums
A Roth conversion is powerful, but the full amount converted counts as income in the conversion year, potentially triggering IRMAA surcharges for the next two years.
Converting $100,000 from a traditional IRA to a Roth in 2024 adds $100,000 to your 2024 MAGI. If your baseline income was $80,000, your MAGI jumps to $180,000, potentially pushing you into a higher surcharge bracket for 2026 and 2027.
However, the long-term math often still favors Roth conversions. After the two-year look-back period passes, converted assets grow tax-free. You avoid Required Minimum Distributions (RMDs), keeping your MAGI lower in future years and avoiding surcharges down the road. You also leave tax-free money to your heirs.
The key is timing. Convert in a year with lower income, perhaps when you've just retired and haven't started Social Security yet. Another strategy is spreading conversions across multiple years. Instead of converting $100,000 in one year, convert $30,000 annually over three years to keep your annual MAGI lower.
Tax-Efficient Withdrawal Strategies to Reduce IRMAA
Your withdrawal strategy is your primary tool for managing MAGI and avoiding surcharges. The order in which you withdraw from different accounts matters enormously.
Tax-deferred accounts (traditional IRAs, 401(k)s): Withdrawals are fully taxable and count toward MAGI. These are your highest-cost withdrawals.
Taxable brokerage accounts: Withdrawals of principal (your cost basis) don't count toward MAGI. Only gains are taxable, often at favorable long-term capital gains rates. This is usually your most tax-efficient source.
Tax-free accounts (Roth IRAs, Roth 401(k)s): Withdrawals of contributions don't count toward MAGI. These are ideal for managing income in years approaching a surcharge threshold.
Health Savings Accounts (HSAs): Withdrawals for qualified medical expenses don't count toward MAGI, a powerful but underused strategy.
In years approaching a surcharge threshold, prioritize withdrawals from taxable accounts and Roth accounts. Save traditional IRA and 401(k) withdrawals for years when other income is lower, or spread them across multiple years.
Using Qualified Charitable Distributions
A Qualified Charitable Distribution (QCD) is one of the most underutilized strategies for managing MAGI. If you're 70½ or older, you can direct up to $100,000 per year from your IRA directly to a qualified charity. The distribution doesn't count toward your MAGI and satisfies your Required Minimum Distribution (RMD) if you have one.
A $50,000 RMD taken as a QCD reduces your MAGI by $50,000 compared to a regular distribution. If that $50,000 would have pushed you over a surcharge threshold, the QCD keeps you below it. You avoid the surcharge, reduce tax liability, and support a charity you care about.
Managing Required Minimum Distributions
Required Minimum Distributions (RMDs) are mandatory withdrawals from tax-deferred accounts starting at age 73. These withdrawals count fully toward MAGI and can push you into a surcharge bracket.
One strategy is reducing your tax-deferred account balances before RMDs begin. Roth conversions in early retirement years shrink your traditional IRA and 401(k) balances, meaning smaller RMDs later. Another approach is aggregating RMDs across multiple accounts, giving you flexibility in managing income.
The Two-Year Look-Back Period and Life-Changing Events
The two-year look-back period is both a constraint and an opportunity. It's a constraint because you can't quickly adjust for a major income spike. It's an opportunity because it creates a planning window.
A life-changing event can break the two-year lock. The Social Security Administration recognizes retirement, loss of income-producing property, death of a spouse, divorce, and significant income decreases. If you experience one, you can file Form SSA-44 to request new income estimates based on current-year expected income.
For example, if you had high income in 2024 but retired and sold a business in 2025, you can file Form SSA-44 to request new surcharge calculations for 2027 and 2028 based on lower retirement income. The key is documenting your life-changing event with retirement letters, divorce papers, property sale documents, or other proof.
How to File SSA-44 for IRMAA Appeal
Form SSA-44, the "Request for Reconsideration of Part B Income-Related Monthly Adjustment Amount," is your tool for appealing a surcharge when income has changed due to a life-changing event.
You have until December 31 of the year following the year your surcharge took effect to file. For example, if your 2026 surcharge was based on 2024 income and your income dropped in 2025 due to retirement, you can file in 2025 or early 2026 to request new surcharge calculations for 2026 and 2027.
Here's how to file:
-
Gather documentation of your life-changing event: retirement letter, divorce decree, property sale documents, or accountant letter describing your income change.
-
Complete Form SSA-44: Download it from the Social Security Administration website or call 1-800-772-1213.
-
Provide your expected current-year income: The Social Security Administration will use your estimated current-year income to recalculate your surcharge, not the historical two-year look-back.
-
Submit your form and documentation to your local Social Security office by mail or in person.
-
Wait for a response: The Social Security Administration typically responds within 30 days.
Common reasons for denial: insufficient documentation, filing after the deadline, the event not meeting criteria, or current-year income still above the threshold. Be specific in your explanation and provide clear documentation.
Common Mistakes That Trigger IRMAA Surcharges
Mistake 1: Ignoring the two-year look-back period. Retirees take large distributions or convert to a Roth without realizing income triggers surcharges two years later. Plan your income two years in advance.
Mistake 2: Bunching income into a single year. Selling a rental property, taking a large distribution, and converting a Roth all in one year spikes MAGI to $250,000, triggering maximum surcharges for two years. Spread major income events across multiple years.
Mistake 3: Not using tax-efficient withdrawal strategies. Withdrawing from a traditional IRA first counts fully toward MAGI, while withdrawals from a taxable account (principal) don't. Withdraw from taxable accounts first.
Mistake 4: Missing the Form SSA-44 deadline. Retiring in 2025 with a major income drop but not filing Form SSA-44 until early 2027 means missing the December 31, 2026 deadline. File within the same calendar year as your life-changing event or by December 31 of the following year.
Mistake 5: Not coordinating with your tax advisor. Ensure your tax advisor and financial advisor communicate about your overall retirement strategy, including Medicare surcharges.
Mistake 6: Overlooking Qualified Charitable Distributions. Taking a $50,000 RMD as a regular distribution adds $50,000 to MAGI. A QCD instead would have reduced MAGI by $50,000 and avoided a surcharge. If you're charitably inclined and over 70½, use QCDs.
Avoiding Medicare IRMAA surcharges requires understanding how your income is calculated, timing withdrawals strategically, and knowing when to appeal. Roth conversions, tax-efficient withdrawals, Qualified Charitable Distributions, and Form SSA-44 appeals can save tens of thousands over your retirement years.

Frequently Asked Questions
How far back does the Social Security Administration look when calculating IRMAA?
The Social Security Administration uses a two-year look-back period to determine your IRMAA surcharges. This means your Medicare Part B and Part D premiums for 2026 are based on your Modified Adjusted Gross Income from your 2024 tax return. If you experience a life-changing event such as retirement, job loss, or significant income reduction, you can file Form SSA-44 to request a recalculation based on current income rather than the two-year-old figure.
Can I appeal an IRMAA surcharge if my income drops?
Yes. If you experience a qualifying life-changing event that reduces your income after the two-year look-back period, you can file Form SSA-44 with the Social Security Administration to request a recalculation. Qualifying events include retirement, loss of income-producing property, change in family status, or reduction in pension or annuity payments. You must file within 60 days of the event and provide documentation of the income change. The Social Security Administration will then adjust your premiums based on your current income for the remainder of that year.
How do Roth conversions affect Medicare IRMAA surcharges?
Roth conversions increase your Modified Adjusted Gross Income in the year you convert, which can trigger higher Medicare Part B and Part D premiums due to IRMAA surcharges. However, strategic timing of conversions across multiple years, combined with tax-efficient withdrawal strategies, can minimize the impact. Since IRMAA uses a two-year look-back, conversions planned for years when your income is already elevated may have less additional impact than conversions during lower-income years. Working with a financial advisor to coordinate Roth conversions with other income sources helps you avoid unnecessary premium surcharges.
Are capital gains included in the income used for IRMAA calculations?
Yes. Capital gains from the sale of investments or real estate are included in your Modified Adjusted Gross Income, which determines your IRMAA surcharges. Long-term capital gains are taxed at preferential rates, but they still count toward your IRMAA threshold. This means selling appreciated assets, including a home if it triggers capital gains, can push you into a higher IRMAA bracket. Planning the timing of asset sales and using tax-loss harvesting strategies can help manage the impact on your Medicare premiums.
