Minimum wage after Prop A

Proposition A, approved in November 2024, raised Missouri’s minimum wage to $13.75 in 2025 and $15.00 on January 1, 2026, and added a statewide paid sick leave mandate. The legislature then passed HB 567, signed July 10, 2025, which kept the $15.00 step, removed the annual inflation adjustments that were to start in 2027, and repealed the paid sick leave sections effective August 28, 2025.

So for 2026: $15.00 an hour, no state paid sick leave mandate, and no state paid family leave or disability program.

State withholding and unemployment

Register for withholding with the Department of Revenue on Form 2643 (the same application covers sales tax), collect a Form MO W-4 from each employee, and file Form MO-941 on the schedule the Department assigns. The 2026 tables run from 0% to 4.7%, and bonuses paid separately from regular wages can be withheld at a flat 4.7%. New hires are reported to the Department of Social Services within 20 days.

Register separately with the Division of Employment Security for unemployment insurance. For 2026 the taxable wage base is $9,000 and new employers pay 2.376% (nonprofits 1.0%). Workers’ compensation insurance is required once a company has five or more employees — part-time workers and corporate officers count — and from the first employee in construction.

The Department sets the MO-941 frequency from the amount withheld: monthly once a company withholds $500 a month in two of the past 12 months, quarterly at $100 or more in a quarter, annual below that, and quarter-monthly payments once withholding reaches $9,000 in each of two months. W-2s go to the Department by January 31.

Kansas City and St. Louis

Missouri’s two largest cities levy a 1% earnings tax. It applies to residents wherever they work and to nonresidents for work done inside the city, so a remote employee who lives in Kansas City is in scope even if the company has no office there. The cities also tax business net profits at 1%.

State law makes each city put its earnings tax to voters every five years. Both were renewed at the April 7, 2026 election, so they run through 2031.

  • Kansas City: 1% earnings tax on residents and nonresidents working in the city; quarterly Form RD-110, annual reconciliation on Form RD-113, filed electronically.
  • St. Louis: 1% earnings tax withheld on Form W-10, plus a 0.5% employer payroll expense tax on Form P-10, filed together quarterly.

Common questions

Do Missouri employers still have to give paid sick leave?

No. Voters passed Proposition A in November 2024, which set the minimum wage path and required one hour of paid sick leave per 30 hours worked. HB 567, signed July 10, 2025, repealed the sick leave sections effective August 28, 2025. Employers may still offer sick leave; they are no longer required to.

Will Missouri’s minimum wage keep rising with inflation?

It is $15.00 an hour in 2026. HB 567 kept the 2026 step but removed the inflation increases Prop A scheduled from 2027, so the rate stays at $15.00 unless the legislature or voters change it, or the federal minimum rises above it.

Do I withhold city tax for a Missouri employee?

If the employee lives in Kansas City or St. Louis, or works inside either city, yes: withhold the 1% earnings tax and file with the city. St. Louis also charges the employer a 0.5% payroll expense tax on wages earned in the city.
