Missouri charges 4% flat state income tax plus local taxes in some areas. Use the tax refund estimator pre-loaded with Missouri rates.
Open Tax Refund Estimator →In Missouri, you may receive refunds at both the federal and state level. Your state refund depends on how your employer's flat 4% withholding compared to your actual Missouri tax liability. Common reasons for a state refund include credits, deductions, or withholding calibrated for a higher income than you actually earned. Local tax refunds in Missouri are handled separately and add another variable. Use this estimator to project both your federal and Missouri state refund amounts.
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.
