Missouri State Income Tax Overview
Missouri uses a graduated income tax with rates from 0% to 4.7%. Income below $1,313 is untaxed, and the rate climbs in half-point steps to a top rate of 4.7% on income above $9,191 for single filers. The top rate fell from 4.8% effective January 1, 2025 after revenue triggers set by S.B. 3 were met. Missouri uses the federal standard deduction, $15,000 for single filers and $30,000 for joint filers, and allows a partial deduction for federal income taxes paid. Because the brackets are so narrow, nearly every full-time worker in Missouri pays the top marginal rate. Kansas City and St. Louis both levy a 1% local earnings tax on residents and on anyone working in those cities.

Understanding Your Missouri Tax Estimate
Your results combine two separate bills: federal tax owed to the IRS, and Missouri state tax owed to the Missouri Department of Revenue. The state return is filed separately from your federal Form 1040, with a state filing deadline of April 15. For the mechanics of how bracket math actually works -- why your effective rate is almost always lower than your top bracket -- see our marginal vs. effective tax rate guide.
Lowering Your Missouri Bill
Pre-tax retirement contributions reduce your federal and Missouri taxable income in the same move -- see our 401(k) contribution limits and HSA limits guides for the current caps. Beyond that, Missouri-specific credits and deductions that don't exist at the federal level are listed at the Missouri Department of Revenue -- worth checking, since these are easy to miss if you only look at federal guidance.
Combined Sales + Income Tax Picture
Missouri's combined state-plus-average-local sales tax rate is 8.28%. If you're self-employed, that's an added layer on top of income tax -- our self-employment tax calculator covers the SE-specific piece separately.
