Missouri payroll guide

Missouri paycheck guide

Missouri’s employer formula annualizes wages, applies a filing-status deduction and the percentage schedule, and rounds withholding to a whole dollar. That last step can explain a small difference from a spreadsheet that keeps cents at every stage.

Use the official 2026 withholding formula and rounding

The 2026 Missouri formula first determines annualized taxable wages, then subtracts the applicable filing-status standard deduction and uses the employer percentage table. The top listed withholding percentage is 4.7%, but it is not applied to every dollar of gross pay. Lower schedule bands and the deduction are part of the calculation.

Missouri directs whole-dollar withholding rounding. The calculator retains that rule, so a state line ending in .00 is expected rather than a missing cent-level calculation. A federal W-4 credit or adjustment affects federal withholding independently; do not assume it is also a Missouri withholding allowance.

Sources

St. Louis and Kansas City earnings-tax checks

St. Louis and Kansas City have city earnings-tax rules separate from Missouri state withholding. The St. Louis guidance distinguishes its employee earnings withholding from an employer payroll expense tax. Do not charge an employer-only tax to yourself as an employee paycheck deduction.

The state calculator does not determine local residency, taxable work allocation, or a city exemption. Use actual local employee dollars in Local tax and verify the city guidance if duties include remote or out-of-city work. Compare the state line first, then local earnings tax and benefit deductions.

Sources

Missouri overtime and supplemental wage methods

For covered nonexempt employees, the federal FLSA generally requires time-and-a-half after 40 worked hours in a workweek. At $27, four qualifying overtime hours add $162. A 44-hour week is not turned into a 40-hour week for overtime purposes by working fewer hours the following week.

Missouri’s formula separately discusses supplemental-wage methods, including a flat-rate option. This page models the overtime as part of a regular check; it does not select a separate bonus or supplemental method. A federal qualified-overtime deduction is not an automatic exclusion from state wages.

Missouri worked examples

Both examples are hypothetical and calculated with this site's withholding engine for a single filer.

Excluded: local tax ($0.00) and other payroll deductions ($0.00) are assumed zero unless shown above. No benefits are included unless listed. This is a partial net under assumptions, not an actual deposit.

Gross is $2,160. The Missouri employer formula’s single deduction and whole-dollar state rounding apply. No St. Louis or Kansas City earnings tax is included.

Twice-monthly salary with retirement

Excluded: local tax ($0.00) and other payroll deductions ($0.00) are assumed zero unless shown above. No benefits are included unless listed. This is a partial net under assumptions, not an actual deposit.

Gross is $3,250, with a $162.50 traditional contribution. The Missouri income-tax line uses regular employer withholding, not the separate supplemental-pay option; local tax is excluded.

Frequently asked questions

Why does Missouri withholding show a whole dollar?

The official employer formula specifies whole-dollar rounding. Keeping pennies in a hand calculation can therefore differ slightly from the supported payroll method.

Are Kansas City or St. Louis deductions already in the state result?

No. Their local employee earnings-tax amounts are separate and must be entered when applicable. The calculator does not establish local work allocation or residency.

Should I add the St. Louis employer payroll expense tax to my deductions?

No. The city distinguishes employer payroll expense tax from employee earnings withholding. Only actual employee deductions belong in the paycheck estimate.

HOW WE ESTIMATE

Understand the calculation.

Default mode follows IRS Publication 15-T Worksheet 1A for a 2020-or-later W-4 and each supported state’s current employer formula. W-4 credits and annual adjustments affect federal withholding; state elections follow the state certificate independently.

Social Security withholds 6.2% on this check’s remaining wages under the $184,500 employer wage cap. Medicare withholds 1.45%, plus 0.9% on wages crossing the employer’s $200,000 threshold, regardless of filing status. Enter taxable wages before this paycheck in the YTD controls. Traditional retirement deferrals remain subject to FICA; qualifying cafeteria-plan health premiums are assumed FICA-exempt.

Annual projections repeat this check. The separate annual tax estimate mode retains a limited legacy liability model and uses filing-status Medicare liability thresholds; it does not represent paycheck withholding. Overtime is not automatically exempt from withholding or FICA. Use W-4 Step 4(b) for an elected overtime-related withholding deduction.

TAX YEAR 2026

Sources & assumptions

Regular resident wage withholding only. Not for 2019-or-earlier W-4 forms, historical pay dates, supplemental/bonus methods, multistate allocation, reciprocity, pensions, or special employer methods. State wage overrides and entered local/other payroll dollars are used as supplied, not independently verified. Each state section identifies its table and effective period. DC withholding is not verified and is unavailable rather than silently using annual brackets. Legacy annual mode omits many state adjustments and later amendments. This is a planning estimate, not tax advice or a guarantee of your employer’s exact result.
