The City of St. Louis has two employer-facing taxes: a 1% earnings tax the employer withholds from the wages of employees who live or work in the city, and a 0.5% payroll expense tax the employer pays on wages earned in the city. Religious, charitable, and certain nonprofit, hospital, educational, and government entities are exempt from the payroll expense tax. On wages, the city says its minimum wage is the same as Missouri's, which is $15.00 an hour as of January 1, 2026.
St. Louis is a payroll tax city, and both of its taxes land on the employer's side of the desk. This page covers the earnings tax withholding, the payroll expense tax, the quarterly and annual returns the city lists, the business license, and what the city says about minimum wage. Missouri registration and the employee test are on bookkeeping for Missouri cleaning businesses.
Earnings tax withholding
The Collector of Revenue's Earnings Tax Department describes the earnings tax as a 1% tax on the wages of employees living or working in the city, withheld by the employer. Employers located in the city withhold it on all employees, regardless of where they work.

The payroll expense tax
The payroll expense tax is 0.5%, paid by the employer on wages earned in the City of St. Louis. Religious, charitable, and certain nonprofit, hospital, educational, and government entities are exempt from it. The city says the two taxes are filed together each quarter on Forms W-10/P-10, with an annual W-3 reconciliation due January 31.

Minimum wage in St. Louis
The City of St. Louis says its minimum wage is the same as the State of Missouri's, because state law bars municipalities from setting a higher rate, and its page dates that state law to August 28, 2017. A $15 figure on the same undated page applies only to City civil service employees. Missouri's minimum wage is $15.00 an hour, effective January 1, 2026, with no change announced as of October 20, 2026.

What two city payroll taxes mean for your books
The two taxes belong in different places. The 1% earnings tax is withheld from your employees' pay, so it sits in a withholding liability account until it's paid over, while the 0.5% payroll expense tax is your own cost and goes to an expense account. I like to try to break the numbers before anyone relies on them: each quarter, the withholding liability gets checked against what payroll actually withheld, and the expense gets checked against wages earned in the city, so a mismatch shows up in the books and not after the W-10/P-10 numbers go to your CPA. Wages earned in the city carry their own tag in payroll, since the payroll expense tax is figured on them.
I'm a bookkeeper, not a CPA or an Enrolled Agent. I keep both city taxes recorded and reconciled; whether your business owes either one, and how they get filed, is a question for your CPA.
