Missouri State Income Tax Overview
Missouri uses a graduated income tax system with rates starting at 2% and reaching a top rate of 4.8% for 2024 on income above $9,000, following a series of phased tax reductions. Missouri allows a deduction for federal income taxes paid, up to $5,000 for single filers and $10,000 for married couples, which can meaningfully reduce state taxable income. The state provides a standard deduction equal to the federal standard deduction. Missouri fully exempts Social Security benefits and 100% of public pension income for qualifying retirees. Military retirement pay is also fully exempt from Missouri state income tax.

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.
