IRMAA Planning Strategies

It all comes down to MAGI

IRMAA is driven by your Modified Adjusted Gross Income — adjusted gross income plus tax-exempt interest. Because Medicare uses a two-year lookback, the income on a given year’s return sets your premium two years later. The goal of planning is not necessarily to earn less; it is to control when income lands and to avoid pushing your MAGI across a bracket threshold in a year that will be used to set your premium.

Roth conversions before age 63

Converting traditional IRA money to a Roth adds to your MAGI in the conversion year. Because the lookback reaches back two years from age 65, the income on your return at age 63 helps determine your first Medicare premiums. Many people front-load larger Roth conversions in their late 50s and early 60s — before that age-63 window — so the conversions do not inflate their initial IRMAA. Roth withdrawals later are not counted in MAGI, which can keep income lower in the Medicare years.

Timing capital gains and large withdrawals

Selling appreciated investments, taking a large IRA distribution, or selling a home can spike your MAGI for one year and lift your premiums two years out. Where you have flexibility, spreading a big sale across two tax years, harvesting gains in a low-income year, or coordinating withdrawals can keep any single year from crossing a threshold.

Qualified Charitable Distributions

If you are age 70.5 or older and charitably inclined, a Qualified Charitable Distribution (QCD) lets you send money directly from your IRA to a qualified charity. The distribution can count toward your required minimum distribution but is excluded from your taxable income, so it does not raise MAGI the way a normal RMD would. That makes QCDs one of the cleaner tools for staying under an IRMAA threshold.

Spread income across tax years

Smoothing income — rather than bunching it — is the theme behind most IRMAA planning. Coordinating when you start Social Security, when you take pension or annuity income, and the size of your discretionary withdrawals can keep you out of a higher tier. Sometimes intentionally realizing a little more income in a low year leaves room to take less in a year that would otherwise cross a cliff.

Watch the cliff

Because each IRMAA tier is a cliff, the most valuable move is often the smallest: trimming MAGI by a few thousand dollars to stay just under the next threshold can save hundreds of dollars a month. Check exactly where you stand with our IRMAA calculator before year-end, while you can still act.

Get help — this is not tax advice

Everything here is educational. IRMAA planning touches your entire tax return, and the right move depends on your full situation, so please consult a qualified tax professional or financial advisor before acting.
