Missouri Income Tax Calculator
Estimate your 2025 combined federal and Missouri income tax — Missouri adds progressive state income tax on top of federal.
Income tax in Missouri
Missouri's 2025 top rate is 4.7%, with the first $1,313 of taxable income exempt and the same brackets for every filing status; its standard deduction matches the federal amounts. Notably, House Bill 594 (2025) made Missouri the first state to fully exempt individual capital gains — effective tax year 2025, capital gains are deducted from Missouri taxable income entirely, so this tool shows no state tax on gains. Kansas City and St. Louis levy a 1% earnings tax not included here.
