Not modeled
Learn why Medicare IRMAA can matter when Roth conversion income increases taxable income, even though it is not modeled by the calculator.
IRMAA is not modeled by the calculator and requires separate professional review.
A Roth conversion can increase current-year taxable income, which may be relevant to Medicare income-related monthly adjustment amount discussions.
The calculator focuses on federal income tax, user-entered state tax, penalty assumptions, and projection math; it does not estimate Medicare premium adjustments.
Users near Medicare age or already enrolled in Medicare should treat IRMAA as a separate review item with a qualified professional.
Review the official source and then discuss the interaction with a qualified professional.
