Understanding Missouri State Income Tax

Missouri uses a progressive state income tax structure. Rates climb through multiple brackets up to a top marginal rate of 4.95% on the highest earners.

This calculator uses 2026 federal brackets, the federal standard deduction, and full FICA withholding (6.2% Social Security up to the wage base and 1.45% Medicare). It then applies the appropriate Missouri state income tax treatment so you can see an accurate annual and per-paycheck take-home estimate for any salary or hourly wage.

How Missouri Take-Home Pay Is Calculated

Start with your gross annual income. Subtract pre-tax deductions such as traditional 401(k) contributions, HSA, FSA, and qualifying health insurance premiums — these reduce both federal and Missouri state taxable wages. Federal income tax is computed on the result using the 2026 IRS brackets and the standard deduction for your filing status.

Missouri state withholding is computed using the progressive brackets shown above, with each portion of taxable income taxed at its own marginal rate. Combined with federal tax and FICA, this produces the per-paycheck net pay shown in the results panel.

Tips for Maximizing Missouri Take-Home Pay

Increasing pre-tax 401(k) and HSA contributions is one of the most effective ways to reduce both federal and state income tax withholding. Reviewing your federal Form W-4 each year — especially after marriage, a new dependent, or a significant raise — keeps withholding aligned with your actual tax liability and prevents large refunds or surprise tax bills at filing time.

Common Questions

What are the Missouri state income tax brackets for 2026?
Missouri uses a progressive bracket system with rates ranging from 0.00% on the lowest taxable income up to 4.95% on amounts above $8,584.
How is progressive state tax calculated in Missouri?
Each portion of your taxable income is taxed at the rate for its bracket. Only the dollars that fall into the top bracket are taxed at 4.95% — earlier dollars are taxed at lower bracket rates.
Does Missouri state income tax apply to retirement contributions?
Pre-tax 401(k), HSA, and FSA contributions typically reduce your Missouri taxable wages, just as they do for federal income tax. Roth 401(k) contributions do not reduce taxable income.
How does Missouri compare to no-tax states like Texas or Florida?
Workers earning the same gross pay will take home less in Missouri than in states with no income tax. The exact gap depends on which brackets your income passes through and any state-specific credits or deductions you qualify for.
Does Missouri have local or city income taxes on top of state tax?
Most Missouri workers pay only the state income tax plus federal and FICA. Check with your city or county for any local employment-related taxes that may apply on top of state withholding.
When is Missouri state tax withheld from my paycheck?
Missouri state income tax is withheld every pay period by your employer based on your state W-4 equivalent and year-to-date wages. Withheld amounts are remitted to the Missouri Department of Revenue on a schedule determined by employer size. Your final state liability is reconciled when you file your state return the following April.
What pre-tax benefits reduce Missouri taxable wages?
Standard pre-tax items — 401(k), 403(b), HSA, FSA, dependent care FSA, qualified commuter benefits, and most employer-sponsored health insurance premiums under Section 125 cafeteria plans — reduce both federal and Missouri taxable wages. Roth 401(k) contributions are after-tax and do not reduce taxable income.
