How Income Tax Works in Missouri (2026)
Missouri uses graduated income tax brackets in 2026, meaning higher income is taxed at progressively higher rates — similar to the federal system. This calculator applies an estimated effective state rate of about 4.7% for middle incomes. On $75,000, that's roughly $3,525 in state income tax, plus $7,670 federal, for a combined income tax bill of about $11,195.
Because Missouri has graduated brackets, your marginal rate (the rate on your last dollar earned) is higher than your effective rate (the blended rate across all brackets). This matters for side income, bonuses, and tax planning: additional earnings above your current bracket threshold are taxed at the marginal rate, not the lower effective rate.

Methodology & sources
Federal tax uses 2026 IRS brackets and standard deductions (Revenue Procedure 2025-32). State tax rates reflect 2026 law from the Tax Foundation and state revenue departments; graduated-state figures are estimated effective rates. FICA uses the 2026 Social Security wage base of $184,500 (6.2%) plus Medicare (1.45%). Local city or county taxes (e.g. NYC, Portland) are not included. Estimates for planning only, not tax advice.
