Use this form for a private-party vehicle sale in Utah. It records the sale between seller and buyer and supports the transfer you’ll complete with the Utah DMV, including the odometer disclosure. Without a bill of sale, the DMV calculates Utah sales tax on the vehicle's fair market value, which may exceed the actual purchase price.

Common questions about selling a vehicle in Utah

Is a bill of sale required to sell a car in Utah?

Utah does not technically require a bill of sale for every private-party vehicle sale, but the DMV strongly recommends one and provides an official Bill of Sale form (Form TC-843). Without a signed bill of sale that states the purchase price, the DMV will calculate sales tax based on the vehicle's "Fair Market Value" under Utah Code Ann. §59-2-102, which may be higher than the actual price paid. A bill of sale documenting the agreed purchase price protects the buyer from overpaying on tax.

Does a Utah bill of sale need to be notarized?

No. Utah does not require notarization of a vehicle bill of sale or the title assignment. The DMV explicitly states that no notary is needed for standard private-party transfers. The valid signatures of the buyer and seller are sufficient to make the document legally binding.

What taxes and fees does the buyer owe?

Utah charges sales and use tax at the local rate, which varies by city and county. The combined state and local rate typically ranges from 6.1% to 8.85% depending on the buyer's location. Unlike most states, Utah does not offer a sales tax exemption for transfers between family members — sales tax is due on all vehicle sales regardless of the relationship between the buyer and seller. Gift transfers with a $0 purchase price are not subject to sales tax, but the purchase price must honestly reflect the transaction. The DMV reviews purchase price documentation for accuracy, and fraudulently underreporting the price triggers an audit with penalties.

Are emissions tests required?

Utah requires emissions testing in five counties: Salt Lake, Davis, Utah, Weber, and Cache. Vehicles registered in these counties must have a current emissions certificate before the DMV will complete the registration. The emissions test is separate from the title transfer process. Vehicles registered in all other Utah counties are exempt from emissions testing.

What is the Utah Person to Person (UPP) online transfer?

Utah offers an online title transfer service called UPP (Utah Person to Person) for vehicles with a current Utah title. Both the buyer and seller can initiate the transfer online through the DMV's Motor Vehicle Portal, upload ownership documents, and pay taxes and fees. A temporary permit can be issued online while the title is being processed. UPP is not available for out-of-state titles — those transfers require an in-person visit to a DMV office.

What should the seller do after the sale?

The seller should remove the license plates unless the plates are being sold with the vehicle — Utah is one of the few states that allows plates to transfer with the vehicle if both parties agree. The seller must provide the buyer with the signed title, the current registration certificate, and the current emission certificate if applicable. Utah law requires the seller to provide the title within 48 hours of the transaction. The seller should keep a copy of the bill of sale for their records.

What if the vehicle has multiple owners?

If the vehicle is titled to more than one person, all owners on the title must sign the bill of sale. Use the "Add a co-seller" option on the form to add the second seller's name and address. Both sellers' names and signature lines will appear on the document. For electronic signing, each co-owner can sign on the same device in sequence, or the document can be passed from one device to another via QR code or shared link. Both buyers can likewise be named on the bill of sale using the "Add a co-buyer" option.

Governing law

Utah vehicle transfers and their supporting records are governed by the Utah Code Annotated. The provisions below set the framework for private-party sales and title transfer.

Utah Code §41-1a-501

Vehicle title transfers in Utah are governed by the Utah Code Annotated, Title 41, Chapter 1a (Motor Vehicle Act), particularly §41-1a-501 (certificate of title required). Sales and use tax at the local rate is administered by the Utah State Tax Commission. The Utah Person to Person (UPP) online title transfer service is available for vehicles with a current Utah title. Emissions testing is required in Salt Lake, Davis, Utah, Weber, and Cache counties. Federal odometer disclosure requirements are established by 49 U.S.C. Chapter 327 and 49 CFR Part 580.

As-is disclosure
