Missouri Sales Tax Calculator

Missouri applies a 4.22% state sales tax to most retail purchases. Counties, cities, and special districts can add up to 5.88% on top, so the actual rate you pay varies by jurisdiction. The statewide average combined rate is 8.39%.

Unlike most states, Missouri taxes groceries — but at a reduced rate of 1.23% rather than the full 4.22%. Local sales taxes generally still apply to grocery purchases at the full local rate. Prepared and restaurant food is taxed at the regular combined rate.

For exact rates by ZIP code or address, use the Missouri Department of Revenue's online lookup. The combined rate at the register is whatever the state rate plus the local jurisdiction add to — and local rates can shift each year as cities pass new measures. Run any purchase amount through the calculator above to see the breakdown.
