Missouri's tax structure provides corporations with one of the most favorable situations in the nation. Only 3.5% of Missouri's tax revenue is derived from corporate income taxes. About 10.8% of the state's revenue comes from sales and gross receipts taxes. In most cases, a company located in Missouri will have a lower corporate tax bill than in other states.
