Missouri Paycheck Calculator

How the Missouri estimate works

Enter gross pay for one pay period, federal W-4 adjustments, and the state details shown above. Federal withholding follows Publication 15-T. Missouri annualizes wages, subtracts the 2026 standard deduction for the selected MO W-4 status, applies the published progressive rates through 4.7%, returns the result to the pay period, and rounds regular withholding to the nearest whole dollar. An explicit MO W-4 Line 3 amount replaces that standard state calculation.

Example: The official Missouri example annualizes $35,000 of wages for a married employee whose spouse works, subtracts $16,100, and returns $59 of monthly withholding. Kansas City and St. Louis earnings tax are separate 1% lines when a confirmed work or residence city triggers them. The calculator does not assume any unentered benefit deduction or invent a tax result.

Weekly, biweekly, semimonthly, and monthly are the supported paycheck frequencies. “Annual salary” is an earnings input and the annual view is a simple period multiplication; neither is an annual payroll-period method. The special Form W-4 adjustment for nonresident aliens is not modeled.

When does Missouri city earnings tax apply? Kansas City and St. Louis each tax residents’ earned income and wages earned by nonresidents working in the city. WageFrame asks for both work and residence city status, counts the same city only once, and does not allocate a paycheck across multiple work locations.
