Missouri has a flat 4.7% state income tax — see your real take-home.
Your offer letter says one number; your bank account says another. This calculator bridges the gap for Missouri: 2026 federal income tax brackets, Social Security and Medicare payroll taxes, and Missouri's a flat 4.7% state income tax, all computed as you type. Results are estimates — they exclude pre-tax deductions like 401(k) contributions and health premiums, tax credits, and local taxes. Kansas City and St. Louis each levy a 1% earnings tax not modeled here.
Missouri has a flat 4.7% state income tax. Kansas City and St. Louis each levy a 1% earnings tax not modeled here. The calculator applies it to your salary automatically and shows the effective (real) percentage at the bottom.
Real paychecks include pre-tax deductions (401(k), health insurance, HSA) that lower taxable income, plus benefits and credits this estimate excludes. Local income taxes, where they exist, are also excluded. Compare the breakdown against your paystub to calibrate.
Use the state dropdown to compare: enter the same salary and switch between Missouri and another state. The take-home difference on an $75,000 salary between the highest- and lowest-tax states runs several thousand dollars per year — real money when evaluating a move.
