St. Louis Local Market Context

Frequently Asked Questions
My crews cross into St. Louis City on some routes — what does the earnings tax cost me?
St. Louis City charges a 1% earnings tax on wages earned and business income sourced inside city limits, and the city-versus-county line is what decides whether it applies. If a crew cleans an account in the City, those wages and your net profit from that work are in scope; the same crew on a St. Louis County account is not. It sits on top of Missouri state income tax rather than replacing any part of it.
Do I charge sales tax on cleaning services in Missouri?
No. Missouri exempts cleaning services from sales tax, so your labor invoices go out without it. Goods are a different matter: supplies sold to a client inside St. Louis City are taxable at the city's combined rate of 9.679%, which is high enough to notice on a large restock. Keep service and product lines separated on the invoice so the taxable portion is obvious to you and to anyone auditing you.
Missouri doesn't require workers' comp until five employees. Can I wait?
You can legally, but it's a bad idea. Missouri's five-employee threshold is one of the higher ones in the country, and your clients set the real bar — most commercial buyers want a certificate from your first hire. Waiting until employee number five means turning down work or scrambling for a policy mid-bid. Get coverage early and treat the state minimum as trivia rather than a plan.
