IRMAA guides

Every guide uses the official 2026 figures, works through a real example in dollars, and cites Medicare, Social Security or the IRS. Start with the basics or jump to the question you have.

Basics

How IRMAA works, which income counts and how it is collected.

Planning

Keep income below the next cliff, or cross it on purpose.

Appeals

When a life change or an error means you are paying too much.

Couples & survivors

Joint limits, the separate-filing trap and the widow's penalty.
