Missouri Paycheck Calculator

Missouri levies a progressive state income tax with rates ranging from 0% to 4.7% for tax year 2025. The top marginal rate of 4.7% was reduced from 4.8% on January 1, 2025, after revenue triggers under Senate Bill 3 were met — continuing a trend of gradual rate reductions in the Show-Me State. The tax applies across eight brackets, with the top bracket kicking in at just $9,191 of taxable income, meaning most working adults in Missouri pay at or near the 4.7% marginal rate on the bulk of their earnings.

Missouri's standard deduction mirrors the federal standard deduction: $15,750 for single filers and $31,500 for married filing jointly in 2025. This significantly reduces your taxable income before brackets are applied.

Here is a worked example for a $75,000 annual salary as a single filer in Missouri: after subtracting the $15,750 standard deduction, your Missouri taxable income is roughly $59,250. The first $9,191 is taxed across the lower brackets (averaging well below 4.7%), and everything above that is taxed at 4.7%. Your total Missouri state income tax comes to approximately $2,680–$2,750, an effective state rate of about 3.6% on gross pay. Add federal income tax ($10,294) and FICA ($5,738), and your total deductions reach roughly $18,800, leaving a take-home of about $56,200 per year (~$4,683/month).

Note: residents who work in Kansas City or St. Louis owe an additional 1% local earnings tax, which further reduces take-home pay by roughly $750/year on a $75k salary. This calculator provides estimates for general planning — your actual withholding depends on W-4 elections, pre-tax benefits, and filing status.
