Calculate Missouri sales tax on any purchase. Missouri charges a 4.225% state sales tax rate, and cities and counties add their own local rates on top. Enter your purchase price and local rate to see the total tax and final price.
Missouri has a state sales tax rate of 4.225%, which is the base rate applied to most tangible goods. On top of that, cities and counties can levy additional taxes, bringing the combined rate anywhere from 4.225% to over 11% in some areas.
The average combined rate across Missouri is about 8.2%. Kansas City has a combined rate around 9.1%, St. Louis city is about 9.68%, and Springfield sits near 8.1%. Rural areas tend to have lower combined rates, often in the 5-7% range.
Missouri exempts certain items from sales tax or taxes them at reduced rates. Groceries (food purchased for home consumption) are taxed at a reduced state rate of 1.225% instead of the full 4.225%. Prescription drugs are fully exempt from state sales tax. Over-the-counter medications are taxable at the full rate.
Missouri also holds a back-to-school sales tax holiday in early August, when clothing, school supplies, computers, and other qualifying items can be purchased tax-free (up to certain dollar limits). Check the Missouri Department of Revenue website for exact dates and qualifying items each year.
