Missouri's statewide sales tax is 4.225%, but your total rate depends on where you buy
Missouri has a base state sales tax of 4.225%. However, most counties and cities add their own local sales taxes on top of that amount. Your total sales tax rate — what you actually pay at checkout — is the combination of state tax plus all local taxes that explore to your location. This means the rate you pay in Kansas City is different from the rate in St. Louis, which is different from a rural county, even though they're all in Missouri.
The total rate you see on your receipt depends on the exact address where you make the purchase. A store in one part of a city might have a different rate than a store two blocks away if they're in different tax districts. This matters most when you're buying something expensive or comparing prices across the state.
Key Takeaways
- Missouri's state sales tax rate is 4.225%, and most counties and cities add local taxes on top of that, making your total rate vary by location.
- Kansas City and St. Louis have among the highest combined rates in the state because they layer multiple local taxes.
- Some counties have rates as low as 5.225% (state only plus minimal local tax), while others exceed 8% when all local taxes are included.
- The exact rate at any store depends on the specific address, since tax districts don't always follow city or county lines.
- You can find your exact local rate by entering your address into the Missouri Department of Revenue's tax rate lookup tool.
How local taxes stack on top of the state rate
Missouri allows counties to add a county sales tax, and cities to add a city sales tax, and special districts (like transit authorities or school districts) to add their own taxes. Each layer is separate, and they all add together. A purchase in downtown St. Louis, for example, is subject to the state tax, the city tax, the county tax, and potentially a transit tax, all at once.
The local rates vary widely. Some counties have no additional local tax beyond the state rate, leaving the total at 4.225%. Others have county taxes ranging from 0.5% to 1.5%, and cities on top of that may add another 1% to 2%. Special districts add even more in some areas. The result is that two locations in Missouri can have sales tax rates that differ by more than 3 percentage points.
Sales tax rates in Missouri's largest cities
Kansas City's combined sales tax rate is 8.6%, making it one of the highest in the state. This includes the state rate, Jackson County's local rate, Kansas City's city rate, and the Kansas City Area Transportation Authority tax. St. Louis city has a combined rate of 8.2%, which includes the state rate, the city's local rate, and other local taxes. Both cities are significantly higher than the state baseline because they layer multiple local taxes.
Springfield, in Greene County, has a combined rate of 8.225%. Columbia, in Boone County, has a combined rate of 7.45%. Smaller cities and rural areas typically have lower combined rates. For example, some areas in the Ozarks have combined rates closer to 5.225% or 6.225%, depending on whether the county and city have added local taxes.
Why rates differ between counties and cities
Missouri's tax structure gives local governments the power to set their own rates to fund schools, roads, public transit, and other services. Counties and cities decide independently whether to add a local tax and at what rate. This creates a patchwork of different rates across the state.
Some counties have chosen not to add a local sales tax at all, keeping the rate at the state baseline. Others have added county taxes to fund specific projects or services. Cities within those counties can then add their own city tax on top. A city in a county with no county tax will have a lower combined rate than a city in a county with a high county tax, even if both cities have the same city tax rate.
How to find the exact rate for a specific address
The Missouri Department of Revenue publishes a sales tax rate lookup tool on its website. You enter a street address, and the tool returns the combined sales tax rate for that exact location. This is the most reliable way to find your rate because tax districts don't always follow obvious boundaries — a street address matters more than a city name.
You can also contact your city or county assessor's office directly. They maintain records of all local tax rates and can tell you the rate for any address in their jurisdiction. If you're buying something online and the seller asks for your address to calculate tax, you can use the Department of Revenue tool to verify the rate they quote you.
Sales tax on groceries and other exceptions
Missouri taxes most purchases, but groceries for home consumption are exempt from sales tax. This means you don't pay sales tax when you buy food at a grocery store to cook at home. However, prepared food — restaurant meals, deli items, hot food — is taxed at the full rate.
Prescription medications are also exempt from sales tax in Missouri. Over-the-counter medications and vitamins are taxed. Clothing is taxed in Missouri, unlike some other states. If you're unsure whether a specific item is taxed, the Missouri Department of Revenue publishes a list of taxable and exempt items on its website.
Frequently Asked Questions
What is the highest sales tax rate in Missouri?
The highest combined rates are in Kansas City (8.6%) and St. Louis (8.2%), where multiple local taxes layer on top of the state rate. Some special districts in other areas may push rates even higher, but these two cities consistently have the highest published rates.
Do I pay sales tax on online purchases from Missouri sellers?
Yes. Missouri requires online sellers to collect and remit sales tax on purchases shipped to Missouri addresses. The rate applied is based on the delivery address, not where the seller is located. If you're buying from an out-of-state seller, tax rules depend on that seller's nexus in Missouri and federal law.
Can the sales tax rate change during the year?
Yes. Local governments can vote to change their tax rates, though changes usually take effect on a specific date (often January 1 or July 1). The Missouri Department of Revenue updates its rate lookup tool when changes occur, so checking the tool before a large purchase is wise if rates have recently changed in your area.
Is there a sales tax on used items or secondhand purchases?
Sales tax applies to used items sold by businesses, including used cars, used furniture, and used clothing from resale shops. Private sales between individuals are generally not taxed, but if you're buying from a business, expect to pay sales tax at the full rate for your location.
How do I know if my city has added a local sales tax?
The easiest way is to use the Missouri Department of Revenue's tax rate lookup tool with your address. You can also call your city or county clerk's office and ask what local taxes explore to your area. They can tell you the city rate, county rate, and any special district taxes in your jurisdiction.
