Missouri Sales Tax Calculator
Figure the tax, the total, or the pre-tax price for any U.S. state or city rate
Missouri imposes a 4.225% state sales tax on most tangible personal property and many services. That base rate is among the lower state-level rates in the Midwest, but Missouri allows cities, counties, and special taxing districts to stack additional local taxes on top — and those local additions average another 4.22 percentage points. The result is an average combined sales tax rate of approximately 8.44%, according to Tax Foundation data, though combined rates in major metros like Kansas City or St. Louis can easily reach 9%–10% or higher depending on the exact district.
One notable Missouri quirk: groceries are not fully exempt. Most states either tax food at the full rate or exempt it entirely, but Missouri takes a middle path — the state sales tax on food eligible for purchase with SNAP benefits is reduced to 1.225% (not the full 4.225%). However, local sales taxes still apply on top of that reduced state rate, so the total on grocery items varies by location.
Here is a quick worked example: on a $100 general purchase in a Missouri location with the average combined rate of 8.44%, you would pay $8.44 in sales tax for a total of $108.44. In a high-rate Kansas City suburb at 9.5%, that same purchase costs $109.50.
To use this calculator, enter the purchase amount in dollars and the sales tax rate for your location. Use 4.225% for the state-only estimate, 8.44% as a statewide average combined rate, or look up the exact rate for your Missouri city at the Missouri Department of Revenue website.
Practical example — Missouri
A $350 television purchased in a Missouri city with a combined rate of 9.1% would add $31.85 in sales tax, bringing your total out-of-pocket cost to $381.85 — while the same $350 spent on qualifying groceries at that location would owe only the reduced state rate of 1.225% plus local taxes.
