Missouri Sales Tax Rate: State vs Combined
The Missouri state sales tax rate is 4.22%. However, most shoppers pay more than the state rate because counties and cities add their own local taxes on top. The average combined rate across all jurisdictions in Missouri is 8.44%, according to Tax Foundation, State and Local Sales Tax Rates 2026. This means a $100 purchase could cost between $104.22 (state only) and more in high-tax localities.
What Is and Isn't Taxed in Missouri
Missouri taxes groceries at the full 4.225% state rate, which is notable because most states exempt essential food items. Missouri taxes clothing purchases at the standard 4.225% state rate, plus any applicable local rates. Prescription drugs are also exempt from sales tax in Missouri.
How to Calculate Missouri Sales Tax
To calculate Missouri sales tax: multiply the purchase price by the applicable rate. For the state rate only: price × 4.22% = tax. For the combined rate: use 8.44% for an average estimate, or enter the exact local rate from your receipt or the Missouri Department of Revenue website. Example: a $200 purchase at the 8.44% combined rate = $16.88 in tax = $216.88 total.
Tips for Accurate Sales Tax Calculations
Always confirm the exact local rate for your specific city or county — the combined average (8.44%) is a statewide mean and may differ from your actual checkout rate. Large purchases like vehicles, appliances, or electronics are where the difference between state-only and combined rates matters most. Keep receipts that show the tax rate used; this helps verify correct tax was charged and supports any refund claims for exempt purchases. If you are making a business purchase, check whether your state offers a sales tax exemption certificate to avoid paying tax on resale items.
Missouri Special Categories: Groceries, Vehicles & City Rates
Missouri has unusual sales tax rules. Per the Missouri Department of Revenue (dor.mo.gov): groceries get a REDUCED state rate of 1.225% (not the standard 4.225%), but local taxes still apply on top, so a grocery purchase in Kansas City typically costs ~5% sales tax versus ~9-10% for prepared food. Motor vehicles use the buyer's home address rate, not the dealer's location rate, paid at title transfer. Major city rates: Kansas City ~9.5%, St. Louis ~9.7-11.7% (with Loop Trolley district), Springfield ~8.1%. Missouri also enacted economic nexus rules (Wayfair) requiring out-of-state sellers with $100,000+ in MO sales to collect tax. Updated 2026-06-17.
Missouri Vehicle Sales Tax: Why the Dealer's Sticker Rate is Wrong
Missouri is one of the few US states that charges vehicle sales tax at the buyer's residence rate, not the dealer's location rate. Per the Missouri Department of Revenue motor vehicle sales tax calculator, this means the effective rate depends entirely on where you live. Buy a $25,000 used car from a Springfield dealer (city rate ~8.1%) but live in St. Louis City (rate ~9.679% with Loop Trolley district) — you pay the St. Louis rate ($2,420 total tax), not Springfield's $2,025. The buyer settles the difference at the Department of Revenue license office when titling, typically within 30 days of purchase (extension available with $25 fee). Trade-in credits reduce the taxable base dollar-for-dollar. Private-party sales trigger the same buyer's-address rate. Practical tip: check your address rate at dor.mo.gov before signing the purchase agreement so the dealer's "out-the-door" price doesn't surprise you at the license bureau. This calculator uses the buyer's ZIP; for a vehicle purchase, enter your home city's combined rate, not the dealer's. Updated 2026-07-14.
Missouri Consumer's Use Tax: What You Owe on Untaxed Online Purchases
If the calculator above returns $0 because a small out-of-state Etsy or Shopify seller didn't collect Missouri tax, you likely owe Consumer's Use Tax — Missouri's mirror-tax for goods bought outside the state and delivered/used in Missouri. Per the Missouri DOR consumer use tax FAQ, the rate matches your local combined sales tax rate (4.225% state + local). Report annually on Form 4340 (Consumer's Use Tax Return) — filed either standalone (if total tax due exceeds $2,000/year) or on your Missouri income tax return Form MO-1040 Line 26 for smaller amounts. Common triggers: private-party out-of-state vehicle purchases, small-batch furniture from Wayfair before nexus, international goods (>$800 duty-free threshold applies but MO use tax still owed). Amazon and Wayfair now collect Missouri tax at checkout post-Wayfair (2018), but many niche sellers still leave the use-tax burden on you. Missouri DOR has been increasingly cross-checking credit-card records to catch unreported use tax since 2023. Updated 2026-07-14.

Missouri does run a back-to-school sales tax holiday in early August (first weekend) where qualifying clothing under $100, school supplies under $50, and computers under $1,500 are tax-free.
What is the combined sales tax rate in Missouri?
The average combined (state + local) sales tax rate in Missouri is 8.44% (Tax Foundation 2026). The state portion is 4.225%; the remainder comes from county, city, and special district (transportation, fire, ambulance) taxes that vary by location. St. Louis city + special districts can push the rate above 11%.
How do I calculate sales tax in Missouri?
Multiply the purchase price by the rate. For state tax only: price × 0.04225. For the average combined rate: price × 0.0838. Example: $50 × 0.0838 = $4.19 tax, total $54.19. For groceries: $50 × 0.01225 (state) + local rate.

Yes — 100% free, no sign-up, no ads inside the calculator, no data leaves your browser. Use it for as many purchases as you want and bookmark for future receipts.
Does Missouri have a sales tax holiday?
Yes. Missouri's Back-to-School Sales Tax Holiday runs the first Friday-Sunday of August each year. During the holiday, clothing under $100 per item, school supplies under $50 per item, personal computers under $1,500, and computer software under $350 are exempt from state sales tax. Local jurisdictions can opt in or out — check your city's participation list on the MO DOR website.
Which rate does Missouri use for vehicle sales tax — dealer's or buyer's address?
Missouri uses the BUYER'S residence rate, not the dealer's location — one of the few US states that does this. Buy a $25,000 car from a Springfield dealer (~8.1%) while living in St. Louis City (~9.68%) and you pay St. Louis's higher rate at the license bureau within 30 days. Trade-ins reduce the taxable base dollar-for-dollar. Check your home ZIP rate at dor.mo.gov before signing the purchase agreement — otherwise the dealer's out-the-door price will short you at title transfer. Source: Missouri DOR.
Do I owe Missouri use tax on tax-free online purchases from small out-of-state sellers?
Yes. Consumer's Use Tax matches your local combined sales tax rate (4.225% state + local). File Form 4340 annually — standalone if total tax due exceeds $2,000/year, or line 26 on Form MO-1040 for smaller amounts. Amazon and Wayfair collect at checkout since Wayfair (2018), but small Etsy/Shopify sellers and international purchases still trigger use tax. Missouri DOR has been cross-checking credit card records to enforce since 2023. Source: Missouri DOR consumer use tax FAQ.
