Kansas City, Missouri has a 1% earnings tax on earned income. Employers withhold it on 100% of taxable wages for employees who live in Kansas City, and on the part of a nonresident's pay attributable to work performed in the city. On wages, Missouri has no local minimum wages, and the state rate is $15.00 an hour.
In Kansas City, Missouri, the local rule that reaches your payroll is a tax, not a wage. This page covers the earnings tax and who owes it, what the employer withholds, the return calendar the city publishes, the business license, and what all of it means for your books. Missouri registration and the employee test are on bookkeeping for Missouri cleaning businesses.
The Kansas City earnings tax
The city's Finance Department describes the earnings tax as 1% on earned income. All Kansas City residents owe it, even when they work outside the city, and nonresidents owe it on income earned inside city limits. The city's Revenue Division collects it.

What the employer withholds
According to the Revenue Division's Tax Guide for Non-Resident Businesses, employers withhold 1% on 100% of taxable wages for resident employees, and on the portion of a nonresident employee's compensation attributable to services performed in Kansas City. Withholding is remitted at the same frequency the business uses for Missouri income tax withholding, with a quarterly Form RD-110 and an annual Form RD-113 due January 31.

The Kansas City business license
The city's KC BizCare Office puts it this way: "In order to work with Kansas City, your business must be registered and licensed unless State Law provides an exemption from licensing." The page says work with, not work in, and it doesn't settle whether a business based outside the city needs a license for jobs there. That one is a question for the city.

Minimum wage and sales tax
Missouri's minimum wage is $15.00 an hour, effective January 1, 2026, with no change announced as of October 20, 2026, and Missouri has no local minimum wages. On sales tax, the Missouri Department of Revenue's janitorial matrix lists residential and commercial cleaning as not taxable, while noting that taxability may depend on the facts and circumstances of a specific transaction.

What the earnings tax means for your books
Residents and nonresidents get handled differently, so the books start with knowing which employees live in Kansas City. From there, every single dollar withheld ties back to a paycheck: all taxable wages for a resident, and only the Kansas City portion for a nonresident, which is why hours worked in the city get tagged in payroll. The withholding sits in its own liability account, on the same calendar as your Missouri withholding, until it's paid over.
I'm a bookkeeper, not a CPA or an Enrolled Agent. I keep the earnings tax withholding recorded and tied to payroll; whether a given wage is subject to it, and how the returns get filed, is a question for your CPA.
