Missouri Automobile Sales Tax on New Cars
When purchasing a new car in Missouri, the sales tax is applied to the purchase price, which includes any dealer fees and add-ons. The state’s general sales tax rate is applied, and additional local taxes will be added depending on the location of the dealership. In some cases, if you’re purchasing a vehicle that is out of state and bringing it to Missouri, you may need to pay the Missouri sales tax at the time of registration.
