Utah Form TC-843 is the State Tax Commission’s bill of sale for a private-party transfer of a vehicle, vessel, or outboard motor. You download it free from tax.utah.gov/forms, fill in the vehicle details, seller and buyer information, sale price, and odometer reading, both parties sign, and the buyer takes it to any Utah DMV or participating county office along with the signed title and a title application.
When You Actually Need the TC-843
If the current certificate of title has clear space for the sale price, date, and both signatures, the title by itself can carry the transfer. The TC-843 earns its place when the title is cramped, damaged, or missing a field the DMV needs. Utah requires the purchase price and date of sale to appear in the transfer paperwork because the DMV uses that figure to calculate sales tax at registration.
A completed bill of sale also protects both sides after the handshake. The seller has written proof they no longer own the vehicle, which matters if the buyer collects parking tickets or toll violations before transferring the title. The buyer has documentation of exactly what they paid. The Tax Commission recommends keeping a copy for your records, and sellers should also report the sale online at dmv.utah.gov under Motor Vehicle e-Services.1Utah State Tax Commission.

Filling Out the Form
The TC-843 has three main sections. Have the current title and both parties’ IDs in front of you before you start. Most errors trace back to working from memory.
Vehicle Information
Enter the Vehicle Identification Number exactly as it appears on the title and the dashboard plate. For watercraft, use the Hull Identification Number instead. Then fill in year, make, model, and body type. Check the VIN or HIN character by character against the title. The DMV rejects paperwork where these don’t match.2Utah DMV. Transfer a Utah Title
Seller Information
The seller writes their full legal name (last, first, middle initial) or business name, with street address, city, state, and ZIP. The name has to match the one printed on the current title. A missing middle initial or a maiden name instead of a married name can trigger an identity-verification hold at the counter.
This section also carries the sale price and date of sale. Write the actual dollar amount the buyer paid. The DMV uses that number for sales tax, and understating the price to shrink the tax bill is something auditors look for.1Utah State Tax Commission. TC-843 Utah DMV Bill of Sale Form
Buyer Information
The buyer enters their full legal name and current residence address. The address determines where the state sends registration renewal notices, so use the one where you actually get mail. If two people are buying together, the connector matters. “And” means both owners must sign to transfer or change the title later. “Or” means either owner can sign alone.3Utah DMV.

Odometer Disclosure
Record the mileage shown on the odometer at the time of sale, with no tenths, and check the box that fits: actual mileage, mileage in excess of the odometer’s mechanical limits, or a reading that is not the actual mileage. The form warns that leaving this blank or providing false information can bring fines or imprisonment.1Utah State Tax Commission. TC-843 Utah DMV Bill of Sale Form
Vehicles 20 or more model years old are exempt. For transfers in 2026, that covers model year 2006 and older, and you can leave the odometer section blank. If you prefer, you can also use the separate Form TC-891 Odometer Disclosure Statement instead of the odometer section on the TC-843.2Utah DMV. Transfer a Utah Title
Signatures
Both the buyer and the seller sign the TC-843. The seller’s signature certifies they are transferring all rights, title, and interest to the buyer. The buyer’s signature confirms they are aware of the sale price and odometer information and that it is correct to the best of their knowledge.1Utah State Tax Commission.

Utah does not require a notary for a title or bill of sale, so the two parties can finish the paperwork between themselves.4Utah DMV. Responsibilities of Buyer and Seller
What the Buyer Takes to the DMV
The bill of sale alone doesn’t finish the transfer. The buyer still has to apply for a new title and registration. Bring:
- The certificate of title, signed by the seller. If a prior lienholder is printed on the title, that lien needs a signed release.
- The completed, signed TC-843.
- Form TC-656, the Application for Utah Title and Registration. Download it from tax.utah.gov/forms ahead of time or fill it out at the office.5Utah State Tax Commission. Vehicle Application for Utah Title and Registration
- Government-issued ID for every owner listed on the new title application.
- An emissions inspection, if you’ll register the vehicle in Salt Lake, Davis, Weber, Cache, or Utah County.2Utah DMV. Transfer a Utah Title
Any Utah DMV office or participating county office will process the transfer; you aren’t restricted to the county where you live.
Sales Tax at Registration
Utah charges sales tax on private-party vehicle purchases, calculated by multiplying the sale price on your bill of sale by the local tax rate. Rates vary by city. For private sales, the DMV applies the rate for the locality where the vehicle will be registered. You can look up your exact rate on the Tax Commission’s sales and use tax rate page at tax.utah.gov/sales/rates.6Utah DMV. Registration Taxes and Fees
You pay this at the DMV when you apply for your new title and registration. Combined state and local rates across Utah generally fall between roughly 6.35% and 9.55%, so on a $10,000 vehicle you could owe anywhere from about $635 to $955 in sales tax, depending on where you live. Have the money ready before you go.
Doing It Online Through UPP
Utah’s UPP (Utah Person to Person) portal lets a buyer apply for title and registration from home. With the original title or a bill of sale from the seller, you can start the application online and even print a temporary permit so you can legally drive the vehicle while you finish an emissions test, VIN inspection, or any other remaining step.7Utah DMV. UPP – Utah Person to Person Online Title Transfers
UPP doesn’t replace the TC-843 or the signed title. It handles the DMV’s side of the paperwork so you don’t have to wait in line at an office.
