Estimated Missouri Car Sales Tax
Missouri's state sales tax on a vehicle is 4.225%, which comes to $1,056.25 on a $25,000 purchase with no trade-in.
Local sales tax is added on top based on where you live, so the calculator asks for your combined local rate. The Department of Revenue's calculator can look it up.
Missouri applies tax to the price less your trade-in allowance, and the Department of Revenue also subtracts rebates from the taxable price.
Missouri Car Title and Registration Fees
Only the $9 registration processing fee is priced here, for a one-year registration ($18 for two). The title fee sits in the Department of Revenue's fee charts and passenger registration is based on taxable horsepower, so the total leaves both out unless you enter them.
