State income tax, by filing status.

Most state rate tables show one column — single. What changes when you marry, or file as head of household, is rarely published at all. Pick your state to see the real difference, in dollars.

Filing status changes a state bill through two mechanisms: bracket thresholds that may or may not widen, and a standard deduction that may or may not double. Each state page below shows both, plus real liability at three incomes across all four statuses — sourced and dated, not inferred from the single-filer schedule alone.
