Missouri Taxes

Missouri taxes individual income at graduated rates topping out at 4.70%. Under the Department of Revenue's 2026 annual rate table, the first $1,348 of Missouri taxable income is taxed at 0%; each next $1,348 band is taxed at 2.0%, 2.5%, 3.0%, 3.5%, 4.0% and 4.5% in turn; and income over $9,436 is taxed at 4.70%. Missouri taxable income is figured after the standard deduction (the department's 2026 worked example uses $16,100). Employers withholding on supplemental wages may use a flat 4.7% rate.

Missouri's state motor-fuel tax is 29.5 cents per gallon: a base tax of 17 cents per gallon (RSMo 142.803.1(1)) plus an additional tax added by 2021 S.B. 262 that phased in over five years — 2.5 cents from July 1, 2021, 5 cents from July 1, 2022, 7.5 cents from July 1, 2023, 10 cents from July 1, 2024, and 12.5 cents "on and after July 1, 2025." The statute schedules no further step after July 1, 2025. Compressed natural gas is taxed at 17 cents per gasoline gallon equivalent and liquefied natural gas at 17 cents per diesel gallon equivalent since January 1, 2025. These are state taxes only.

Missouri property tax is assessed and collected locally. Your county assessor determines market value — for real property as of January 1 of each odd-numbered year, for personal property every January 1 (vehicles by the October NADA guide). The assessor then applies a percentage set by the property's classification to get assessed value: residential real property is assessed at 19% of true value (RSMo 137.115), and other classes carry their own percentages. Local taxing districts (county, schools, cities and others) then apply their levies to the assessed value, so rates and bills vary by county and district. The Missouri State Tax Commission hears property tax appeals and explains paying under protest.

Groceries taxed at a reduced 1.225% state rate (plus local); repeal bills are pending.
