Understanding the 2026 IRMAA Brackets: What Federal Retirees Need to Know
By FederalPensionAdvisors
Retirement planning isn’t just about savings and pensions it’s also about managing healthcare costs. For federal retirees, Medicare can offer excellent coverage, but it also comes with potential cost increases based on your income. One of the most important—and often overlooked factors is IRMAA, the Income-Related Monthly Adjustment Amount. As we look ahead, understanding the 2026 IRMAA brackets is essential to protect your retirement income and avoid unexpected costs.
What Is IRMAA?
IRMAA is an additional charge added to your Medicare Part B and Part D premiums. It's not a penalty, but rather an adjustment based on your income level. Specifically, the Social Security Administration looks at your Modified Adjusted Gross Income (MAGI) from two years prior. So for 2026, the income reported on your 2024 tax return will determine whether you owe IRMAA and how much.
This adjustment affects higher-income individuals and couples, often including federal retirees who receive pensions, TSP distributions, and Social Security benefits. Even a one-time income increase, like a large TSP withdrawal or real estate sale, can push you into a higher IRMAA bracket.
Why IRMAA Matters for Federal Retirees
Many federal retirees are surprised to learn that their income can trigger higher Medicare premiums. With CSRS or FERS pensions, Social Security, and investment income, it’s easy to exceed the IRMAA thresholds even if you don’t consider yourself “wealthy.”
The impact can be significant. Instead of the standard Medicare premium, you could be paying hundreds of dollars more each year if your income crosses into a higher IRMAA tier. That’s money that could otherwise go toward travel, family, or simply enjoying your retirement.
How the 2026 IRMAA Brackets Could Impact You
While the official IRMAA brackets for 2026 won’t be released until later, they are adjusted annually for inflation and tend to increase modestly. However, even slight increases in income can still move you into a higher bracket. That’s why it’s so important to understand the factors that affect your MAGI and take steps to manage it strategically.
The bottom line: if you’re not planning for IRMAA now, you could be leaving money on the table or worse, be hit with surprise premium hikes in retirement.
Strategies to Minimize IRMAA
The good news is that with careful planning, IRMAA can often be managed or even avoided. Here are several proven strategies federal retirees can use:
1. Time Your Income Wisely
Large withdrawals from your TSP or other retirement accounts can bump your income above an IRMAA threshold. By spreading those withdrawals over multiple years or tapping different income sources strategically, you may be able to keep your income below the next bracket.
2. Consider Roth Conversions
Roth IRAs don’t generate taxable income when withdrawn, which can help lower your MAGI in retirement. A partial Roth conversion strategy early in retirement (or just before) may increase taxes in the short term but reduce IRMAA exposure in future years.
3. Use Qualified Charitable Distributions (QCDs)
If you're age 70½ or older, you can direct up to a certain amount per year from your IRA to a qualified charity. This not only satisfies your required minimum distribution (RMD) but also doesn’t count toward your MAGI.
4. Delay Social Security (If Strategic)
For some retirees, delaying Social Security benefits can reduce taxable income in early retirement years, potentially keeping them below IRMAA thresholds.
5. Appeal an IRMAA Determination
If you've experienced a major life change like retirement, death of a spouse, or divorce—you can appeal your IRMAA decision using SSA Form 44. Many retirees successfully reduce their IRMAA this way.
