Missouri charges 4% flat state income tax plus local taxes in some areas. Use the bonus tax calculator pre-loaded with Missouri rates.
Open Bonus Tax Calculator →When you receive a bonus in Missouri, your employer typically withholds at the federal supplemental rate of 22%, plus Missouri's flat 4%, and FICA at 7.65%. Local income taxes in some parts of Missouri take an additional cut. The combined withholding can make bonuses feel heavily taxed, though your actual liability may differ from withholding at year-end. This calculator shows both the withholding and the true tax on your bonus in Missouri.
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.
The table below shows what you actually keep at five salary levels in Missouri, accounting for federal tax, FICA, and Missouri's flat 4% state tax plus estimated local taxes.
