Car sales tax in Missouri starts at a state rate of 4.225% on the net purchase price, and local city and county taxes stack on top, pushing the combined rate above 10% in some jurisdictions.1Missouri Department of Revenue. Buying a Vehicle You pay the tax when you title the vehicle with the Department of Revenue, not when you pay the seller. The rule is the same whether you buy from a dealership, a neighbor, or an out-of-state seller.
The State Rate and Your Local Add-On
Every vehicle buyer pays the 4.225% state rate. City and county rates layer onto that, ranging from 0% in some rural areas to as high as 6.5% in certain jurisdictions.2Missouri Department of Revenue. Motor Vehicle Sales Tax Rate Chart What you owe depends on where you live, not where you bought the car. Two people buying identical cars at the same dealer can walk out with very different tax bills.
A buyer in a low-tax county might pay a combined 4.225%. Someone in a high-tax urban area could face 10.725%. The Department of Revenue publishes a rate chart listing the combined rate for every city and county, and license office staff will look yours up when you title the vehicle.2Missouri Department of Revenue.

What Missouri Actually Taxes
The taxable amount is the net purchase price: the final price after subtracting any trade-in allowance and applicable rebates.3Missouri Department of Revenue. FAQs – Motor Vehicle Licensing Both manufacturer rebates and dealer discounts reduce that figure. Buy a $30,000 car with a $5,000 trade-in and a $2,000 manufacturer rebate, and you pay tax on $23,000.
At a dealership, the trade-in credit is automatic. The dealer records the allowance on the bill of sale, and it comes off the price before tax is calculated.4Missouri Revisor of Statutes. Missouri Code 144.025 – Transactions Involving Trade-in or Rebate, How Computed If your trade-in plus rebate exceeds the new car’s price, you owe zero sales tax on that purchase.
Missouri also allows a credit if you sell a vehicle within 180 days of buying a replacement. The sale price of the old vehicle reduces the taxable amount on the new one, even if you handled the two transactions separately.5Missouri Department of Revenue.

If the purchase price is unknown, or the evidence you provide is not satisfactory to the Department of Revenue, the director may appraise the vehicle and set a value for tax purposes.6Missouri Revisor of Statutes. Missouri Code 144.440 – Purchase Price of Motor Vehicles, Trailers, Boats and Outboard Motors This tends to come up with private sales where the stated price looks suspiciously low.
Buying From a Private Seller
Private-party buyers owe the same combined rate. The catch is the trade-in credit: Missouri’s trade-in allowance applies only to transactions with a motor vehicle dealer, so you cannot reduce your taxable amount by trading a car to a private seller.7Legal Information Institute. 12 CSR 10-103.350 – Sales Tax on Motor Vehicles You pay tax on the full purchase price.
Even trades between private parties are a different story. The Department of Revenue provides an Even-Trade Bill of Sale (Form 1957) for exactly this.8Missouri Department of Revenue. Bill of Sale or Even-Trade Bill of Sale If you and another person swap vehicles of equal value with no cash changing hands, neither party owes sales tax. Title and registration fees still apply.
Bringing a Car in From Another State
If you buy a vehicle in another state and bring it to Missouri, you owe Missouri sales tax when you title it here. Missouri credits any sales or use tax you already paid to the other state, and you pay only the difference. If the other state’s rate was lower, you owe the gap. If it was higher, you don’t get a refund.7Legal Information Institute. 12 CSR 10-103.350 – Sales Tax on Motor Vehicles
One timing rule matters: if you registered and regularly operated the vehicle in another state for at least 90 days before bringing it to Missouri, no Missouri tax is due at all. Inside that 90-day window, the full tax applies, minus any credit for taxes paid elsewhere.7Legal Information Institute. 12 CSR 10-103.350 – Sales Tax on Motor Vehicles If you bought from an out-of-state dealer and had a trade-in, bring proof of the trade-in value so you receive the credit when titling in Missouri.1Missouri Department of Revenue.

Transfers That Owe No Tax
Several kinds of transfers are exempt from Missouri sales tax entirely.
- Gifts. When a vehicle is given with no money or other consideration involved, the recipient owes no state or local sales tax. The giver completes the gift section of a General Affidavit (Form 768) and provides it to the new owner along with the assigned title, and both parties sign a Notice of Sale or Transfer.9Missouri Department of Revenue. Selling a Vehicle10Missouri Department of Revenue. Missouri General Affidavit
- Religious or charitable organizations. Vehicles purchased, owned, and used by a qualifying nonprofit for its regular functions are exempt, with a copy of the organization’s Missouri Sales Tax exemption letter submitted at titling.11Missouri Department of Revenue. Motor Vehicle Sales Tax Exemptions
- Insurance replacements. If your vehicle is stolen or totaled, the insurance proceeds can be credited against the purchase price of a replacement bought within 180 days, reducing or eliminating tax on the replacement.5Missouri Department of Revenue. Missouri Sales and Use Tax Exemptions and Exclusions From Tax
- Rescinded sales. If a sale is rescinded within 60 days, Missouri refunds the sales tax already paid.5Missouri Department of Revenue. Missouri Sales and Use Tax Exemptions and Exclusions From Tax
The gift exemption is not restricted to family. If a friend gives you a car with no payment involved, the transfer qualifies. What matters is that no money or valuable consideration changes hands.
The 30-Day Deadline
You have 30 days from the purchase date to title the vehicle and pay the sales tax. On day 31, a $25 late penalty applies. The penalty grows by another $25 for each additional 30-day period you remain late, capping at $200.1Missouri Department of Revenue. Buying a Vehicle The penalty is separate from your tax bill and won’t be waived for forgetting. The clock starts on the purchase date shown on your bill of sale, not the day you drove the car home.
Paying the Tax
You pay in person at a Department of Revenue contract license office when you title the vehicle. Accepted methods include cash, personal check, cashier’s check, money order, and Visa, Mastercard, Discover, or American Express. Card payments carry a convenience fee of 2.0% plus $0.25 per transaction, charged by the card vendor rather than the state.1Missouri Department of Revenue. Buying a Vehicle On a $1,500 tax bill, that surcharge runs about $30, so paying by check or cash saves real money.
If you’d rather skip the office visit, you can mail your complete application package to the Department of Revenue’s central office in Jefferson City. Once processed, the state mails your new title to the address on the application. The mail route works, but it takes longer and leaves you without a title in hand during processing.
