How Much Is Sales Tax on a Car in Missouri?

A hard truth every car buyer must face is that the price of ownership will be so much more than the vehicle's price tag. It includes insurance, maintenance, and registration. And yes, it includes taxes. In Missouri, the sales tax bill often comes when you title the vehicle, after you've agreed on the price. If you live in Ellisville, a $25,000 used car with no trade-in or rebate brings another $2,247 due at the license office. That's the kind of number you want in the budget before you pick out the truck.

Bo Beuckman Quality Ford is in Ellisville, but buying a car here doesn't make you an Ellisville taxpayer. Missouri uses your home address to set the local portion. A customer from Ballwin, Chesterfield, or St. Charles will have a different bill from one who lives down the road from us.

What is the Missouri car sales tax rate in 2026?

Missouri's state vehicle sales tax is 4.225%. Local sales tax comes on top. The Missouri Department of Revenue's rate chart lists an additional 4.7630% for an Ellisville resident, bringing that example to 8.988%.

Keep in mind, rates will change across St. Louis County, sometimes even between nearby addresses.

How do you calculate sales tax on a car in Missouri?

The basic math is purchase price minus the dealer trade-in and any documented rebate from the seller or manufacturer, multiplied by the combined rate for your address. A down payment reduces your loan balance. It doesn't reduce the price Missouri taxes.

The state's vehicle-tax regulation limits a trade-in deduction to a purchase from a motor vehicle dealer. If you buy from a private seller, handing over your old car as part of the deal doesn't count as a dealer trade-in. Missouri has a separate 180-day allowance when you sell a vehicle you own.

Here's the math for a buyer who lives in Ellisville:

In the F-150 examples, the trade-in saves $1,348.20 in tax, and the rebate saves another $179.76. Both amounts belong on the purchase paperwork used to calculate the tax.

When do you pay Missouri car sales tax?

For most Missouri purchases, you pay vehicle sales tax when you apply for title at a license office, after you buy. You have 30 days from the purchase date to title the vehicle and pay the tax. The title penalty starts at $25 on day 31, increases by $25 for each additional 30-day period, and tops out at $200. A temporary permit doesn't erase that deadline.

What else should you budget for beyond merely the taxes?

The license office collects title and registration fees along with the sales tax. Here are the amounts that often come up in a car purchase:

The table covers the standard state charges for a passenger car. Your vehicle and paperwork can change the picture:

• Pickup registration: Trucks use a different registration schedule based on weight and use. An F-150 buyer's plate cost won't come from the passenger-car range above.
• Personal property tax records: For new plates, the license office asks for last year's paid personal property tax receipt or a statement of non-assessment. Missing it can mean another trip, even when you have the money ready.
• Safety inspection: Under the DOR's titling rules, a vehicle is exempt on age and mileage grounds only if it's less than 11 years old and has fewer than 150,000 miles. The certificate must generally be no more than 60 days old. If a Missouri dealer had it inspected within 60 days before the sale, the certificate can be accepted up to 90 days after the inspection.
• Emissions inspection: A certificate no more than 60 days old is required for covered vehicles registered in St. Louis City or St. Louis, St. Charles, or Jefferson County. A new vehicle with a manufacturer's statement of origin is exempt from that titling requirement.
• Dealer administration fee: This is separate from the state fees above. Bo Beuckman lists a $620 administration fee in our site pricing information, so include it when you compare the full price across dealerships.

How does Missouri's 180-day vehicle sale allowance work?

Under Missouri's 180-day rule, money from a vehicle you sell can reduce the taxable price of another vehicle you buy or contract to buy within 180 days before or after the sale. It works in either direction. Selling your old truck in March and buying another in July fits the window, even though no truck changed hands at the dealership.

Bo's Value Your Trade tool gives you an estimate before you decide whether to sell privately or trade. We also buy vehicles for cash when the owner isn't buying another one from us.

Can you include the sales tax in a car loan?

Some lenders will finance the sales tax as part of your vehicle loan. If yours approves it, the tax becomes part of the balance you repay with interest. You still need to know whether the dealership or you will make the payment when the vehicle is titled.

At Bo's Finance Center, our team can put both payment options side by side and explain who will pay the tax when the title is filed. That makes the amount due at the license office clear before you drive home.

What if you buy in another state or move to Missouri?

A Missouri resident who buys across state lines still has to settle Missouri vehicle tax at titling. If you already paid sales tax to another state, Missouri credits that payment against the amount due here when you show proof. For the drive home, you'll need a valid temporary permit or plates you're allowed to transfer. The DOR's paperwork list includes the assigned out-of-state title (or manufacturer's statement of origin for a new vehicle) and proof of any dealer trade-in.

If you're moving to Missouri, you have 30 days after becoming a resident to title your vehicle. Missouri doesn't assess sales tax when the vehicle was titled in your name in another state for more than 90 days. For 90 days or less, Missouri assesses its vehicle tax and credits the tax you can document paying to the other state.
