How can I lower my MAGI for Medicare?

Lower the income that lands in your AGI. The most reliable moves are qualified charitable distributions from an IRA, timing Roth conversions for low-income years, contributing to an HSA while you are still eligible, and spreading large withdrawals or capital gains across years so no single year crosses a threshold.

Do municipal bonds lower IRMAA?

No. This is a common mistake. MAGI for IRMAA adds tax-exempt interest, including municipal bond interest, back to your AGI. Munis can be tax-efficient for income tax, but they do not reduce the MAGI that sets your IRMAA.

Do tax deductions lower my MAGI?

Itemized and standard deductions do not, because MAGI is built from your AGI, which is figured before those deductions. Only items that reduce your AGI itself, such as an HSA contribution or a qualified charitable distribution, lower your MAGI.

Does a qualified charitable distribution lower MAGI?

Yes. A QCD sends money directly from your IRA to a charity and is excluded from your AGI, so it lowers your MAGI dollar for dollar. It also satisfies your required minimum distribution. It is one of the most effective tools for charitable retirees.

Can I undo a high-income year that caused IRMAA?

Not directly, but the surcharge is not permanent. Because IRMAA uses your income from two years earlier, a one-time spike falls off once that year ages out. If a life event caused the change, you may be able to appeal sooner.

How to Reduce Your MAGI to Avoid IRMAA

Start with your number and your nearest threshold

Before you change anything, find out where you stand. MAGI for IRMAA is your adjusted gross income plus any tax-exempt interest, and what matters is how close that figure is to the next bracket. A reduction only pays off if it carries you back under a threshold.

Run your income through the IRMAA calculator to see your tier and how many dollars sit between you and the next cliff, then check what counts as MAGI so you know which levers actually move the number.

Moves that actually lower your MAGI

Use a qualified charitable distribution. If you are charitably inclined and old enough to qualify, sending money straight from your IRA to a charity keeps that amount out of your AGI entirely. It also counts toward your required minimum distribution. See QCDs and IRMAA for the rules.

Time Roth conversions for low-income years. A conversion raises your MAGI in the year you do it, so it is not a reducer by itself. The strategy is to convert during lower-income years, before required minimum distributions begin, so your future RMDs are smaller and your MAGI in later years stays lower. Timing is everything here: Roth conversions and IRMAA walks through it.

Contribute to an HSA while you are eligible. HSA contributions reduce your AGI directly. The catch is that you cannot contribute once you enroll in Medicare, so this lever is for the years before then. See HSAs and Medicare.

Spread out withdrawals and gains. A large IRA withdrawal, a big capital gain, or the sale of a property can spike a single year. Where you have a choice, draw from Roth or taxable accounts in years you are near a line, harvest losses to offset gains, and split a large sale across tax years so the income does not all land at once.

Moves that do not lower your IRMAA MAGI

Some popular ideas feel like they should help but do not, and acting on them can cost you.

Municipal bonds. Their interest is tax-exempt for income tax, but IRMAA specifically adds tax-exempt interest back into MAGI. Moving money into munis does not reduce your surcharge.
Itemized or standard deductions. These lower your taxable income, but MAGI is based on AGI, which is calculated before them. A large charitable deduction on Schedule A does not lower your MAGI, which is exactly why a QCD, which reduces AGI, is the better charitable tool for IRMAA.
Tax credits. Credits reduce the tax you owe, not your AGI, so they have no effect on your MAGI or your IRMAA tier.

Remember the 2-year lookback

IRMAA uses your income from two years ago, so the moves you make this year affect your premium two years out. That lag is a planning advantage: you can see a high-income year coming and act before it sets a future surcharge. Read the 2-year lookback explainer so the timing is clear.

When the cliff is close

If you are sitting just above a threshold, even a small reduction can save a full tier of surcharge for the whole year. That is where these levers earn their keep. For a step-by-step approach to staying under the next bracket, see how to avoid the IRMAA cliff.
