Tennessee Car Payment Calculator (With Sales Tax)

Tennessee taxes a car purchase in three layers, and only one of them grows with the price. The 7% state sales tax applies to the whole taxable price. The local option tax reaches only the first $1,600. A separate 2.75% state single-article tax covers the slice between $1,600 and $3,200. This calculator opens with Tennessee preselected so that tax is part of the amount you finance.

Enter the price, down payment, trade-in, term and APR. The preset uses the 7% state rate. Because the local and single-article pieces are capped, together they add no more than $88 in a county with a 2.75% local rate, so add that amount to the fees field if you want the figure exact. The sections below show how each piece is worked out and what a $30,000 purchase looks like on a 60-month loan.

How Tennessee sales tax works on a car

The Tennessee Department of Revenue’s June 2025 dealership manual sets out the method. The standard 7% state rate applies to the entire sales price. The local option tax depends on the jurisdiction where the vehicle is purchased and applies only to the first $1,600 in most of the state. Hamblen and Hancock counties are the exceptions, where it applies only to the first $300. The state single-article tax of 2.75% applies to the portion of the price from $1,600.01 to $3,200, so it can never exceed $44.

What counts as the price matters too. The manual treats a dealer’s document processing fee as part of the vehicle’s sales price, so it is taxed. Accessories installed by the dealer before or at the sale count as part of the same single article. Titling fees are not taxed as long as the dealer passes them through at the amount actually paid to the county clerk. Extended warranties are taxed separately, and the $1,600 local cap does not apply to them, so local tax runs on the full warranty price.

Does a trade-in reduce sales tax in Tennessee?

Yes. When you trade in a vehicle as part of the purchase, tax is computed on the net difference between the price and the credit the dealer gives you (Tenn. Code Ann. § 67-6-510(a), as cited in the Department’s dealership manual). The trade must be of like kind and listed on the invoice by model and serial number. You do not have to prove that tax was paid on the trade-in. An insurance payout on a wrecked vehicle is not a trade-in and earns no credit.

On the $30,000 Nashville example, a $5,000 trade-in cuts the state tax base to $25,000. State tax falls to $1,750, while the capped local and single-article amounts stay at $36 and $44, for a total of $1,830. That is $350 less than with no trade. Cash you put down works differently. It is part of what you pay for the car, so it shrinks the loan but not the taxable price.

Tennessee title and registration fees

The Department lists the standard plate fee for a passenger vehicle at $26.50 and tells buyers to check with their county clerk for additional registration fees. Its military-registration page lists the title fee as $11. A Department notice raised the county clerk’s fee for each title application from $5.50 to $8.50 effective July 1, 2022, so confirm the exact title charge with your clerk. The Department also notes that counties may levy a wheel tax on top of the plate fee.

These fees are not part of the sales tax base when the dealer passes them through at cost. If you plan to roll them into the loan, add them to the calculator’s fees field.

Worked example: $30,000 car in Nashville, $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 assumes no trade-in and leaves title and registration fees out.

1. Sales tax: $30,000 × 7% = $2,100, plus $1,600 × 2.25% = $36, plus $1,600 × 2.75% = $44, for a total of $2,180.
2. Amount financed: $30,000 + $2,180 − $3,000 = $29,180.
3. Monthly payment at 7.00% APR for 60 months: $577.80.
4. Total of payments: $577.80 × 60 = $34,668.00, of which $5,488.00 is interest.
5. Without the tax, the amount financed would be $27,000 and the payment $534.63. Financing Tennessee’s tax adds $43.17 a month, or $2,590.20 over the loan.

Where to pay and title in Tennessee

The Department titles and registers vehicles in coordination with county clerks across the state. On a dealer purchase, the dealership calculates the tax using the rules above, and the Department’s manual notes that licensed dealers usually submit the lien paperwork to the county clerk. A private sale is taxable too. Tennessee includes one-time sales of motor vehicles between individuals in its definition of business, and the Department publishes a separate tax manual for county clerks, who handle these transactions. Sales between spouses, lineal relatives and siblings are not taxable.

Before you sign, compare the calculator’s result with your budget using our guide to how much car you can afford. Check the vehicle’s history with the VIN decoder if you are buying used. If the dealer offers an extended warranty, read whether an extended warranty is worth it first, because in Tennessee it is taxed at the full local rate. To compare loan offers side by side, use the auto loan calculator.
