Missouri levies a flat 4% state income tax on all taxable income regardless of how much you earn. This makes tax planning straightforward: for every additional dollar you earn, 4 cents goes to Missouri. However, certain localities in Missouri impose their own income taxes, which effectively raise the combined state and local rate above 4%. Be sure to check whether your city or county adds a local income tax.
