The sales tax on a car in Tennessee is 7 percent of the full purchase price at the state level, plus a local option tax and a state single article tax that together add no more than $88 on top. That produces an effective rate that ranges from roughly 7 percent on expensive vehicles to about 9.75 percent on cheaper ones, depending on the local rate in the county where the sale is taxed.
How the Three Layers Stack
Tennessee taxes a vehicle purchase in three pieces, each applied to a different slice of the price.
- The state sales tax is 7 percent, applied to the entire price with no cap.
- The local option tax is set by each county or city, must be a multiple of 0.25 percent, and cannot exceed 2.75 percent. For any single item of personal property, it applies only to the first $1,600 of the price. At the 2.75 percent ceiling, that caps the local piece at $44.1Justia. Tennessee Code 67-6-702 – Tax Authorized
- The state single article tax is 2.75 percent, and it fills the gap above the local cap. It applies to the portion of the price from $1,600.01 to $3,200, adding at most another $44.2Tennessee Department of Revenue. Single Article and Special Tax Rates
Anything you pay above $3,200 is taxed only at the flat 7 percent state rate. The combined local and single article layers cannot exceed $88 no matter how expensive the vehicle is.
A Worked Example
Say you buy a used car for $25,000 in a county with a 2.25 percent local rate. The three layers work out like this:
- State sales tax: $25,000 × 7% = $1,750
- Local option tax: $1,600 × 2.25% = $36
- State single article tax: $1,600 × 2.75% = $44
Total: $1,830, or about 7.32 percent effective. On a pricier vehicle the effective rate falls closer to 7 percent, because the fixed $80–$88 in local and single article tax becomes a smaller share of the bill.3Tennessee Department of Revenue. SUT-6 – Single Article Tax – Overview and Application
What Price the Tax Applies To
The tax is calculated on the total consideration the seller receives, not just the number on the window sticker. Documentary fees, dealer preparation fees, and any business tax the dealer passes through to you are part of the taxable price. Accessories or parts the dealer installs at or before the sale and lists on the bill of sale are treated as part of the vehicle.4Tennessee Department of Revenue. County Clerk Sales and Use Tax Guide for Automobiles and Boats
Title and registration fees are excluded from the taxable base as long as they are separately stated on the invoice and actually remitted for titling and registration. GAP insurance is also excluded when it appears as a separate line item.5Tennessee Department of Revenue. County Clerk Sales and Use Tax Manual for Automobiles and Boats
Extended warranties and service contracts work differently. Their full price is taxed at the state rate plus your full local rate, and the $1,600 single article cap does not shield them. The local tax applies to the entire warranty price rather than only the first $1,600.6Tennessee Department of Revenue. Sales of Warranty or Service Contracts
Trade-Ins, Rebates, and Discounts
A trade-in reduces the taxable price. If you buy a $30,000 car and trade in a vehicle for $10,000, you pay tax on the $20,000 difference. The trade-in does not have to be the same type of item as what you’re buying, provided the dealer grants the credit on the sales document.7Justia. Tennessee Code 67-6-510 – Computation on Trade-ins
Manufacturer incentive payments also come off the taxable base. If a manufacturer program pays the dealer $2,000 to reduce your price, that $2,000 is deducted before tax is calculated.8Justia. Tennessee Code 67-6-341 – Credit for Sales Tax Due on Motor Vehicle Manufacturers Incentive Payments A straight dealer discount that isn’t manufacturer-funded works the same way: tax applies to what you actually pay after the discount.9Tennessee Department of Revenue.

Who Collects the Tax and When
Buying From a Dealer
Licensed dealers collect the full sales tax at the time of sale as agents of the state. The dealer remits the tax to the Department of Revenue and gives you documentation showing what was paid, which you then present to the County Clerk when applying for title and registration.10Legal Information Institute. Tennessee Compilation of Rules and Regulations 1320-05-01-.03
Buying From a Private Party
No one collects tax at a private sale. Instead, you owe use tax, calculated the same way as sales tax, and pay it directly to the County Clerk when you title and register. The base is the total consideration you paid, including any amount paid to a third party such as a lienholder.4Tennessee Department of Revenue. County Clerk Sales and Use Tax Guide for Automobiles and Boats
Buying Out of State
If you buy in another state and bring the vehicle to Tennessee, you owe Tennessee use tax when you register it here, but you get credit for any sales or use tax already paid to the other state. If the other state’s rate was lower, you pay only the difference; if it was higher, you owe nothing more.11Tennessee Department of Revenue. Credit for Sales or Use Tax Paid in Another State
Leases Work Differently
A leased vehicle is not taxed on the full sticker price upfront. Instead, the 7 percent state rate applies to each lease payment as it comes due.12Tennessee Department of Revenue. SUT-43 – Calculating Sales Tax on a Lease of Tangible Personal Property
The single article caps still apply, but they measure cumulative payments rather than the vehicle’s value. Local tax hits the first $1,600 of payments, the state single article tax covers the next $1,600, and after cumulative payments cross $3,200 only the 7 percent state rate applies to what follows.12Tennessee Department of Revenue. SUT-43 – Calculating Sales Tax on a Lease of Tangible Personal Property
Family Transfers and Military Exemptions
Transfers between certain close relatives are fully exempt. The exempt group covers spouses, siblings, parents, children, grandparents, grandchildren, great-grandparents, and great-grandchildren, plus the spouses of your children, grandchildren, and great-grandchildren. Both parties sign the Affidavit of Non-Dealer Transfers under penalty of perjury, certifying the relationship and the amount paid. If nothing changed hands, the price is reported as zero and no tax is owed.13Tennessee Department of Revenue. Affidavit of Non-Dealer Transfers of Motor Vehicles and Boats
For a sale to someone outside that family group, a stated price of 75 percent or less of fair market value counts as a “low selling price” and can trigger additional scrutiny at the County Clerk’s office, with fair market value drawn from an authoritative pricing guide such as the N.A.D.A. Official Used Car Guide.
Active-duty service members stationed in Tennessee, or at a military reservation partially within the state, are exempt from sales and use tax on a motor vehicle purchase. The exemption also covers Tennessee National Guard and reserve members in the Active Guard and Reserve program stationed in the state, and guard and reserve members called to active duty in a combat zone, though the combat zone exemption expires 90 days after orders release the member from the zone. You present a copy of your official military orders, and the vehicle must be titled and registered in your name alone or jointly with a spouse or lineal relative. Boats and trailers do not qualify, though camper trailers do.14Justia. Tennessee Code 67-6-303 – Armed Forces
Penalties and Interest for Late Payment
If you don’t pay on time, Tennessee adds 5 percent of the unpaid tax for every 30 days (or fraction of 30 days) the payment is late, up to a maximum of 25 percent. The minimum penalty for a delinquent return is $15 even when little or nothing is owed.15FindLaw. Tennessee Code Title 67 – 67-1-804
Interest accrues on top of that. For the fiscal year running July 2025 through June 2026, the rate on delinquent tax is 11.50 percent annually.16Tennessee Department of Revenue.
