Sales tax on a car in Tennessee
Tennessee charges a state sales tax of 7% on vehicle purchases.
Local sales tax of 1.5% to 2.75%, depending on the county or city, applies only to the first $1,600 of the vehicle price in most places and to the first $300 in Hamblen and Hancock counties.
A state single article tax of 2.75% also applies to the part of the price between $1,600 and $3,200. The 7% state rate applies to the entire price.
Does a trade-in lower the tax?
Tax is computed on the difference between the sales price and the credit given for the trade-in, which must be listed as a trade-in on the invoice.
Example, state tax only. On a $30,000 car with a $10,000 trade-in, the taxable amount is $20,000, so the state tax is about $1,400. Without the trade-in it would be $2,100. Local taxes and fees are extra.
Dealer doc fees in Tennessee
Tennessee Motor Vehicle Commission advertising rules require a dealer to disclose the amount of any document preparation or processing fee and to state that it is excluded from the advertised price. No official statement on whether the amount is limited was found.
The documentation fee is taxed along with the vehicle.
Whatever the rule, the fee is part of your out-the-door price. Ask for it in the written quote and negotiate the total, not the line. See dealer fees explained.
Title and registration
Titles and registrations are handled by the Tennessee Department of Revenue, Vehicle Services (through county clerks).
Also worth knowing
- Document processing fees are part of the vehicle's sales price for tax purposes and are not treated as a separate article, so they do not add local tax when the vehicle price already exceeds the local single article limit.
- Private sales of motor vehicles between individuals are also subject to sales or use tax.
- A trade-in deduction cannot be larger than the sales price of the vehicle being purchased.
