• Sales tax: Missouri state rate is 4.225%; Kansas City adds local rates, totaling approximately 9.975% in the city

Kansas City Earnings Tax

Kansas City, Missouri imposes a 1% earnings tax on gross compensation earned by residents and non-residents who work within city limits. This is a significant consideration for employers – you must withhold and remit the earnings tax quarterly. More info: kcmo.gov/business
