Missouri paycheck withholding calculator
Estimate state withholding per paycheck and avoid surprises.
How this calculator works
Step 1 annualizes your wages using your pay frequency and optional year-to-date data. This helps the calculator approximate your full-year Missouri taxable income.
Step 2 applies Missouri’s graduated brackets (marginal 0%) to estimate your total state tax and compares it to your projected withholding across all remaining paychecks.
Step 3 produces a per-paycheck adjustment so you can update your state withholding request with payroll.
Frequently asked questions
What if my pay changes mid-year?
Update the gross pay or YTD wages and recalculate. The tool assumes your current pay continues for the rest of the year.
Do I need to include bonuses?
Include bonuses in your YTD wages or increase gross pay for the period if you expect more bonus income.
Is this official withholding guidance?
No. This tool provides an estimate to help you decide on a state withholding change.
