Utah vehicle sales tax starts at a 4.85% state rate and climbs with local add-ons to a combined rate of roughly 6.1% to 9.05%, depending on where the sale is taxed.1Utah Legislature. Utah Code 59-12-103 – Sales and Use Tax Base, Rates, Effective Dates, Use of Sales and Use Tax Revenue A dealer collects the tax at closing; a private-party buyer pays it at the DMV when titling and registering the vehicle.
How the Rate Is Built
The 4.85% state figure combines a 4.70% general sales tax with a 0.15% statewide levy.1Utah Legislature. Utah Code 59-12-103 – Sales and Use Tax Base, Rates, Effective Dates, Use of Sales and Use Tax Revenue Cities and counties add their own local option taxes on top, which is why the combined rate swings so widely between a rural county and a metro area with transit levies.
Which local rate applies depends on the type of sale. A Utah dealer charges the rate at the dealer’s location. For a private-party sale where you pay at the DMV, the rate is based on your registration address.2Utah State Tax Commission. Publication 5 – Motor Vehicle Sales and Use Tax Look up the exact combined rate for any address on the Utah State Tax Commission’s rate page before you budget.
Who Collects the Tax
Dealer Sales
A licensed Utah dealer collects sales tax at closing and remits it to the Utah State Tax Commission. You will not pay sales tax again at the DMV, and the DMV will not accept a sales tax payment on a dealer transaction.2Utah State Tax Commission. Publication 5 – Motor Vehicle Sales and Use Tax Check the receipt before you leave the lot to confirm the tax amount is right.
Private-Party Sales
Private sellers do not collect tax. You pay it at the DMV when you title and register.3Utah Division of Motor Vehicles. Responsibilities of Buyer and Seller Bring a complete bill of sale (Form TC-843) showing the year, make, model, VIN, sale price, date of sale, odometer reading, and both parties’ names and addresses, and the DMV taxes you on the price you paid.4Utah State Tax Commission. TC-843 – Utah Vehicle Bill of Sale Show up without one, or with a bill of sale missing required details, and the DMV taxes you on fair market value instead, which is typically higher than what you actually paid.
Fair market value is based on the depreciated cost new as defined in Utah Code 59-2-102. If you disagree with that number, you can obtain a certified appraisal from a licensed and bonded Utah auto dealer or an authorized insurance adjusting firm, and the DMV will use the lowest of the fair market value, the appraisal, or an acceptable bill of sale.3Utah Division of Motor Vehicles. Responsibilities of Buyer and Seller
Do not underreport the price. The state audits these transactions, and the fraud penalty is 100% of the unpaid tax or $500, whichever is greater.5Utah Division of Motor Vehicles. UPP – Utah Person to Person Online Title Transfers
What the Tax Is Calculated On
Tax applies to the net purchase price, not the sticker price. Two adjustments change that number.
Manufacturer Rebates
Utah treats manufacturer rebates as nontaxable, so they reduce the amount you pay tax on. Buy a $35,000 truck with a $3,000 manufacturer rebate and you pay tax on $32,000. The rule holds whether the rebate comes to you directly or the dealer applies it as a down payment.2Utah State Tax Commission. Publication 5 – Motor Vehicle Sales and Use Tax Buyers coming from states where rebates are taxable often assume otherwise.
Trade-In Credit
When you trade in a vehicle at a dealership, the trade-in value comes off the purchase price of the new vehicle, and sales tax is calculated on the reduced net figure shown on the purchase agreement. A $30,000 vehicle with an $8,000 trade-in is taxed on $22,000.
Trade-in credit only works through a dealer. Sell your old car privately and use the cash to buy another one from a private seller and there is no offset; the DMV taxes the full amount on the bill of sale.
Vehicles Bought Out of State
Buy a vehicle in another state and bring it to Utah and you owe Utah use tax at registration, at the same rate as sales tax for your location. Utah gives you credit for sales tax already paid to the other state, so you owe only the difference. Pay 5% elsewhere with a 7.75% Utah combined rate and you owe the remaining 2.75% when you register.
Going the other direction, Utah exempts the sale if the vehicle will not be registered or used in the state. To qualify, the vehicle must not be registered in Utah and must either not be used here at all or used only long enough to drive it to the border, up to 30 days for personal use.6Utah Legislature. Utah Code 59-12-104 – Exemptions
Myths About Exemptions
Utah’s exemptions are narrower than many buyers expect. Two widely believed ones do not exist.
Family Transfers Are Taxed
Utah does not exempt vehicle transfers between family members. Selling a car to a child, spouse, or parent triggers sales tax the same as any other private sale. Gifted vehicles are also taxable, calculated on fair market value if no purchase price is reported.5Utah Division of Motor Vehicles. UPP – Utah Person to Person Online Title Transfers Several neighboring states do offer family exemptions, which is where the confusion comes from.
Farm Vehicles Are Taxed
Utah’s agricultural producer exemption covers items used primarily and directly in commercial farming, but it explicitly does not apply to vehicles that must be registered with the state.7Utah State Tax Commission. TC-721 – Utah Sales Tax Exemption Certificate A truck or tractor that needs plates pays sales tax regardless of how it is used on the farm.
Exemptions That Do Apply
- Vehicles purchased in Utah but immediately registered and used in another state, subject to the border rule described above.6Utah Legislature. Utah Code 59-12-104 – Exemptions
- Sales made by religious or charitable organizations in the conduct of their regular charitable functions.8Utah Legislature. Utah Code 59-12-104.1 – Exemptions for Religious or Charitable Institutions
Military Stationed in Utah
Active-duty members stationed in Utah but domiciled elsewhere hit a rule that surprises many: buy a vehicle in Utah and drive it here and you owe Utah sales tax, even if you register the vehicle in your home state.9Utah Division of Motor Vehicles. Nonresidents – Students, Military, Other The Servicemembers Civil Relief Act protects against certain state taxes like personal property tax; it does not shield you from sales or use tax on a vehicle purchased and operated in Utah.
Penalties for Late Registration
New Utah residents have 60 days from establishing residency to title and register a vehicle brought from out of state.10Utah Legislature. Utah Code Title 41 Chapter 1a Part 2 – Registration For an in-state private-party purchase, register promptly since operating an unregistered vehicle on Utah roads is not legal. Dealer purchases usually roll registration into the sale.
If the Motor Vehicle Division finds you out of compliance, the initial penalty is $150 with 60 days to fix it. Miss that window and the penalty rises to the greater of $500 or a percentage-based penalty on any unpaid sales tax.10Utah Legislature. Utah Code Title 41 Chapter 1a Part 2 – Registration Those penalties stack on top of the tax you already owe.
