How much is sales tax in Missouri?
The Missouri state base is 4.225 percent, which sits on the lower end nationally. However, counties and cities stack their own taxes on top of this foundation. The combined minimum stands at 4.225 percent where only state tax applies, but the combined maximum hits 11.721 percent in Saint Ann. Across all 1,194 taxing jurisdictions, the average rate is 7.33 percent, reflecting substantial local variation.
Even neighboring zip codes can have dramatically different rates because each city and county sets its own local add-on percentage. A zip code tells you nothing about the actual tax obligation—you need the street address to determine which city and county apply, and therefore which combination of local rates stack on top of the state base.
What's taxed and what's exempt in Missouri
Groceries are taxable in Missouri, and so is clothing. No exemptions for either category means your customers pay the full combined rate on food and apparel purchases.
Software as a service is not taxable in Missouri, which helps SaaS businesses. Prescription medicine is exempt from tax. Prepared and restaurant food is subject to tax at the full combined rate for that address.
Do you have to collect Missouri sales tax? (Economic nexus)
Like most states after the 2018 Wayfair decision, Missouri requires out-of-state sellers to register and collect once their sales into the state cross an economic-nexus threshold. That line is commonly around $100,000 of sales into Missouri per year, and some states also count a number of separate transactions — but the exact figure, and whether the transaction count still applies, change from time to time. Confirm Missouri's current threshold before you rely on it.
If you sell into Missouri from out of state, the practical question is whether you've crossed that line. Watching your sales into each state is how you know when you're on the hook — and it's the kind of thing that's easy to miss until a notice shows up.

How to calculate Missouri sales tax
The math itself is simple: multiply the taxable price by the combined rate for the buyer's location. A $100 order at 7.326% means about $7.33 in tax. The hard part is getting the right rate for every address, keeping it current as rates change, and doing it fast enough to run inside a checkout.
That's what Sefro does. One API call returns the combined state, county, city, and special-district rate for any US address, sourced from state Departments of Revenue and refreshed weekly.
