What is IRMAA?
IRMAA stands for Income-Related Monthly Adjustment Amount. It's a Medicare surcharge that most people never hear about until it hits them.
Everyone on Medicare pays a base Part B premium (~$175/mo in 2024). But if your income exceeds certain thresholds, Medicare charges you extra — on top of that base. A lot extra. Up to $420/mo more per person at the highest tier.
For a married couple both on Medicare at the highest tier, that's $10,000/year in extra premiums — on top of regular Medicare costs.
The 2024 IRMAA tiers (single filer)
Married thresholds are double these amounts.
The Cliff Problem
IRMAA tiers are cliffs, not ramps. One extra dollar of income can jump you to the next tier and cost $840–$2,400 more per year. This is why careful IRA withdrawal planning matters so much in retirement.
It Uses 2-Year-Old Income
Medicare looks at your tax return from 2 years ago to set your premium. A one-time income spike (selling a house, large IRA withdrawal) can hit you 2 years later. Plan large distributions carefully.
How to Reduce It
Roth conversions before 63 avoid future IRMAA. Qualified Charitable Distributions (QCDs) from IRAs don't count toward MAGI. Municipal bond income doesn't count. Strategic withdrawal sequencing matters enormously.

Read the guide →How this works: Federal income tax uses 2024 single/married brackets with standard deduction (including age 65+ addition). SS taxation uses the provisional income formula — up to 85% may be federally taxable. State income tax uses actual bracket data at your income level. Medicare IRMAA uses 2024 CMS tables based on estimated MAGI. IRMAA is based on income from 2 years prior — plan Roth conversions carefully. Does not include state property tax, sales tax, or long-term care costs. Not financial advice — consult a tax professional.
