Missouri Car Payment Calculator (With Sales Tax)

Missouri handles vehicle tax differently from most states. You pay the 4.225% state sales tax plus the local sales tax of the city or county where you live, not where you bought the car. You pay it to the Department of Revenue when you title the vehicle, which must happen within 30 days of purchase. This calculator opens with Missouri preselected at the 4.225% state rate.

Enter the price, down payment, trade-in, term and APR. Local sales tax is not in the preset, so enter your combined state and local rate in the tax field for an accurate payment. The Department’s online sales tax calculator can estimate the local amount for your address. The sections below cover how the tax is figured, the credits that lower it, title and plate fees, and a worked $30,000 example.

How Missouri vehicle sales tax works

According to the Missouri Department of Revenue, the state rate is 4.225% and it is based on the net purchase price of the vehicle, meaning the price after any rebate or trade-in. On top of that you pay the local sales taxes of the city or county where you live. Two buyers paying the same price at the same dealership can therefore owe different amounts.

Timing matters as much as the rate. You have 30 days from the purchase date to title the vehicle and pay the sales tax. On the 31st day a $25 title penalty applies, and it grows by another $25 for every additional 30 days, up to $200.

Buying out of state does not avoid the tax. If you paid sales tax to another state, Missouri credits it, but you must show proof and you pay the difference if the other state’s tax was lower. If the vehicle was titled in your name in another state for more than 90 days, no Missouri sales tax is assessed.

Trade-ins, rebates and Missouri’s 180-day credits

A trade-in or rebate reduces the taxable price directly. On a $30,000 car, a $5,000 trade-in lowers the state portion from $1,267.50 to $1,056.25. If the trade-in went to an out-of-state dealer, bring proof of it when you title in Missouri, such as a copy of the assigned title or the dealer invoice showing the trade-in amount.

Missouri also gives credit when you sell your old vehicle yourself instead of trading it in. To get the sales tax allowance, submit a bill of sale or Notice of Sale (Form 5049) when you title the new vehicle. The purchase and sale dates must be within 180 days of each other. The vehicle you sell does not have to be like the one you buy, and the Department’s own example pairs buying a car with selling a boat. A similar allowance covers an insurance total-loss settlement plus your deductible when you buy a replacement within 180 days.

Missouri title, registration and processing fees

When you title a newly purchased vehicle and buy new plates, the Department lists an $8.50 title fee and a $9 title processing fee. Passenger vehicle registration is priced by taxable horsepower, which is printed on the title or the title application:

Add a registration processing fee of $9 for one year or $18 for two years. A 30-day temporary permit costs $5 plus a $9 processing fee at a license office. For new plates you also need a paid personal property tax receipt, or a statement of non-assessment, from your county for the previous year. You need a safety inspection unless the vehicle is under 11 years old with fewer than 150,000 miles. Residents of St. Louis City and Jefferson, St. Charles and St. Louis counties also need an emissions inspection unless the vehicle has a manufacturer’s statement of origin.

Worked example: $30,000 car, $3,000 down, 60 months

This example uses a 7.00% APR. That rate is hypothetical, chosen only to show the arithmetic, and it is not a quote or a market average. It also uses a 3.000% local rate for illustration, which is not the rate of any particular city or county. It assumes no trade-in or rebate and leaves title and registration fees out.

1. State tax: $30,000 × 4.225% = $1,267.50.
2. Local tax: $30,000 × 3.000% = $900.00. Total tax: $2,167.50.
3. If the tax is included in the loan: $30,000 + $2,167.50 − $3,000 = $28,167.50 financed, for a payment of $557.75 a month at 7.00% APR over 60 months. Total of payments: $33,465.00, of which $5,297.50 is interest.
4. If you pay the tax in cash at the license office: $27,000 financed, for a payment of $534.63, but you need $2,167.50 available within 30 days of purchase.
5. Borrowing the tax costs $23.12 a month, or $1,387.20 over the loan.

Because Missouri collects the tax when you title the vehicle, confirm before you sign whether your loan includes the tax or whether you will owe it at the license office.

Where to pay in Missouri

You title the vehicle, pay the sales tax and buy or transfer plates at any Missouri license office. The Department accepts cash, personal checks payable to the Missouri Department of Revenue, cashier’s checks, money orders, and Discover, American Express, Visa and Mastercard. Card payments carry a vendor convenience fee of 2.0% plus $0.25 per transaction.

Once you know the payment, check it against the rest of your budget with how much car you can afford and price coverage with the auto insurance calculator. To compare lender offers, use the auto loan calculator. If you are buying from a private seller, run the VIN decoder first.
