Missouri paycheck calculator 2026 – how it works
Paycheck estimates start with gross pay for the selected pay period. Federal income tax withholding follows IRS Form W-4 rules. Missouri state income tax withholding is estimated using an effective rate approach based on Missouri’s published progressive system, which in reality uses annualized wages, standard deductions by filing status, and official percentage formulas. FICA payroll taxes include Social Security and Medicare.
Examples
If your gross pay increases, estimated Missouri state withholding generally increases proportionally under this estimate model. Actual Missouri withholding may change differently depending on filing status, standard deduction thresholds, pay frequency, and rounding applied by employer payroll systems.
Limitations and important notes
Missouri officially calculates withholding using annualized wages, filing-status-specific standard deductions, and a published percentage formula or wage tables. This calculator does not fully replicate those steps. Local city earnings taxes, such as St. Louis or Kansas City earnings taxes, are not included unless stated otherwise. Results should be used for planning purposes only.
