State Marginal Tax Rate

A user-estimated state income tax rate applied to the taxable conversion.

The state marginal tax rate is an assumption used to estimate state tax on a taxable Roth conversion. State treatment varies widely, so the calculator treats this as a user-controlled educational input rather than a verified state-specific tax conclusion.
