Missouri bookkeeping: two city earnings taxes, and one tax the employer pays itself.
Missouri’s two largest cities tax earnings: Kansas City and the City of St. Louis each levy 1%, and St. Louis adds a 0.5% payroll expense tax the employer pays. Remote and hybrid work makes both harder, because for non-residents the tax follows where the work was done. We keep it straight in your own QuickBooks file, remotely, on a written fixed-fee scope.
Missouri bookkeeping: the state sales tax is 4.225%, with local rates on top. Kansas City and the City of St. Louis each levy a 1% earnings tax, withheld from residents and from non-residents who work in the city; for a non-resident, the taxable part is pay for work physically performed inside the city. The City of St. Louis also levies a 0.5% payroll expense tax paid by the employer, filed with the earnings tax quarterly on Forms W-10/P-10. The City of St. Louis sits inside no county, so a St. Louis County address is not in the city. TechBrot keeps the books in your own QuickBooks file; your tax professional files.

What a Missouri business actually tracks.
A Kansas City, Missouri agency with staff who live in Kansas withholds the city’s 1% earnings tax only on the pay for days they worked in the city; the days they worked from home in Kansas are not the city’s. That is a record the books have to keep, pay period by pay period.
A downtown St. Louis firm has a second layer: the 0.5% payroll expense tax, paid by the firm itself, not withheld from anyone, and easy to miss because no paycheck shows it. Work done across the city line in St. Louis County carries no payroll expense tax, and no earnings tax for a non-resident.
Five Missouri facts your books have to reflect.
As verified from the Department of Revenue’s, Kansas City’s and the City of St. Louis’s pages for our Missouri page.
