Medicare Part B premiums could nearly double by 2035, potentially costing retirees $5,000 annually for basic coverage. Higher earners face additional surcharges that can erase Social Security cost-of-living adjustments.

Here’s how affluent retirees can mitigate the impact:

1. Defuse the IRMAA tax bomb Income-Related Monthly Adjustment Amount (IRMAA) surcharges kick in if your income exceeds federal thresholds. Because Medicare uses tax returns from two years prior, financial planning at age 63 directly affects premiums at 65. Smooth income streams and avoid large withdrawals from traditional retirement accounts.

2. Execute strategic Roth conversions Before required minimum distributions (RMDs) begin at age 73, convert portions of traditional IRAs to Roth accounts. Roth withdrawals are tax-free and don’t count toward IRMAA income limits-keeping future premiums lower.

3. Maximize a health savings account (HSA) If you’re still working with a high-deductible health plan, fund your HSA to the legal maximum. Contributions are tax-deductible, grow tax-free, and can be withdrawn tax-free for medical expenses-including future Medicare premiums.

4. Donate your RMDs At 73 or older, use a qualified charitable distribution (QCD) to send RMDs directly to charity. This satisfies withdrawal requirements without increasing taxable income-helping avoid IRMAA spikes.

5. Ruthlessly shop your coverage every year Don’t auto-renew Medicare Advantage or Part D plans. During annual open enrollment, compare total out-of-pocket costs using the official Medicare Plan Finder. Sometimes Original Medicare plus a Medigap policy offers better long-term value than zero-premium alternatives.
