City Earnings Taxes in Missouri
Two cities in Missouri levy a local earnings tax: Kansas City and St. Louis. Both charge a flat 1% on wages earned within city limits. Critically, this applies to anyone who works in the city — not just residents. If you commute into Kansas City or St. Louis for work, you owe the 1% tax even if you live in the suburbs.
Residents of these cities who also work there pay 1% on all wages. Residents who work outside the city still owe 1% on their earnings. The tax is generally withheld by employers located within city limits.
No other Missouri city has a local earnings tax. If you live and work outside Kansas City and St. Louis, the calculator above reflects your complete tax picture.
