Why this site exists
IRMAA can turn a Roth conversion, RMD, capital gain, home sale, or other taxable event into a Medicare premium surprise two years later. IRMAA Check makes the threshold and surcharge math easier to inspect before the decision is final.
How we work
Calculators use published Medicare and Social Security information, show source links, and state when the underlying figures were reviewed. Guides focus on useful explanations and route readers to official sources where possible.
How the site is funded
The site is building a business through clearly labeled educational sponsorships and may later use display advertising. Sponsors do not receive authority over calculator results or editorial conclusions.
Important: IRMAA Check provides educational estimates, not tax, legal, investment, Medicare enrollment, or individualized financial advice.
