Your 2024 tax return may be affecting your 2026 Medicare premium.
Consider a couple whose 2024 joint modified adjusted gross income was above $342,000 and no more than $410,000. If both spouses have Medicare Part B in 2026, each pays $527.50 per month instead of the $202.90 standard premium.
That’s $324.60 extra per person, per month—or $7,790.40 for the year for two spouses in Part B income-related adjustments alone. A Part D adjustment may add more.
Medicare generally looks back two tax years. If you’ve since retired and your income has fallen, you may be able to ask Social Security to reconsider the adjustment.
Before a large Roth conversion or retirement account withdrawal, ask: What could this do to my Medicare premium two years from now?
If a Medicare notice surprised you, let’s connect it to your retirement income plan.
