In a Utah private sale, the seller signs off the title (no notary needed), and you pay sales tax on the price at the DMV when you title and register the car, at the rate where it will be registered, which is 8.45 percent in Salt Lake City as of October 1, 2026. Plates usually leave with the seller unless the bill of sale says they are included. The seller's registration expires the moment the car changes hands, so plan on a $6 temporary permit, and expect an emissions test if you live in Salt Lake, Davis, Weber, Cache or Utah County.
I checked all of this against the Utah DMV and Tax Commission sites on October 16, 2026. Utah's DMV sits inside the State Tax Commission, which explains why so much of this is about tax. The good news is that a Utah-to-Utah transfer can often be done online through the Utah Person to Person (UPP) service on the Motor Vehicle Portal. The less good news: out-of-state titles, Non-Repairable brands and cars with a pending salvage notice cannot use it, and those mean an office visit.
What a negotiable title looks like
The DMV's responsibilities of buyer and seller page says it is unwise to rely on a seller's promise to "get the title to you," even though Utah law requires a seller to provide one within 48 hours. Get it at the sale or keep your cash. The title has to belong to this car, so compare the VIN on the paper to the VIN on the dash and door. Every owner joined by "and" must sign; "or" means one signature is enough. The page says no notary is needed to sign off a Utah title, so do not pay for one.
If a lien shows on the front, make sure the lender has signed the release. If the seller cannot find a Utah title, they can fill out Form TC-123, the Application for Duplicate Utah Title, and sign both Part 1 and Part 2; that form can stand in for the title. The transfer a Utah title page also wants the purchase date, price and an odometer disclosure filled in for vehicles under 20 years old, plus Form TC-656 and government ID for every new owner.
The bill of sale sets your tax
Utah's bill of sale is doing real work. The DMV says a bill of sale should list both names and addresses, the seller's signature, the full vehicle description with VIN, any trade-in and the net price, written in ink. Bring one that meets those rules and the tax is based on the price on it. Show up without one and the DMV calculates tax on "Fair Market Value," the depreciated cost new, which on a rough, cheap car can be more than you paid. A certified appraisal, at your cost, can fight that.
The Tax Commission's Form TC-843 bill of sale covers all of it and has a box I like: the seller checks whether the license plate is included with the sale or not. Do not write a fake low price. The DMV FAQ says underreporting gets you an audit, and the fraud penalty is likely 100 percent of the tax or $500, whichever is greater. Utah also has no family exemption, so buying from your brother still means tax.
How much tax, in real numbers
The rate is the combined rate where the car will be registered. The Tax Commission's rate chart effective October 1, 2026 shows Salt Lake City at 8.45 percent, West Valley City and Provo at 7.45 percent and Logan at 7.30 percent. So a $9,000 sedan registered in Salt Lake City costs about $760 in tax, or about $670 in Provo, before title and registration fees. Run the DMV's fee estimator before you shake hands, because all taxes and fees are due when you apply, permit included. Our used car sales tax guide compares other states.
Plates, permits and the 20-day seller rule
Under Utah Code 41-1a-701, the registration expires when ownership transfers. Unless the plate transfer is part of the deal, the seller has to pull the plates and, within 20 days, send them to the DMV or put them on another vehicle. If plates do go with the car, you apply to have them assigned to you.
The DMV's temporary permits page lists a $6 permit, issued once you pay the title and registration fees and tax; the local office decides how long it runs. A 96-hour in-transit permit runs $2.50 if you only need to move an unregistered car with proof of ownership and insurance. I could not find a fixed "title within X days" deadline on the DMV pages, but since you cannot legally drive without a registration or permit, the practical deadline is the day you buy.
Emissions and VIN inspection
The inspections page lists an annual safety inspection only for commercial vehicles (since January 1, 2018). Emissions are the hurdle. In Salt Lake, Davis, Utah and Weber counties, the 2026 tables require tests for model years 1996 through 2020, with newer cars tested every other year (2024 and 2022 this year). Cache County tests 1996 to 2020 every other year by even or odd model year. Ask for the seller's current certificate.
If the car is being titled in Utah for the first time, as with any out-of-state purchase, it needs a VIN inspection. The page says a DMV employee can do it at no extra charge. Run through our VIN verification checklist before you pay, and check NMVTIS, which the Utah DMV itself points buyers to. A title reading "rebuilt-restored" is a different purchase; see our Utah rebuilt-restored title brand post.
Check the history yourself
The DMV's private-party page opens by warning about curbstoners, people flipping cars from the curb with the title in someone else's name. A report you run yourself is the cheapest filter, and our CARFAX for private-party sales post covers what to read first. CarVins resells CARFAX and AutoCheck under license; we are not affiliated with either company or Experian. Mid October 2026 pricing runs about $5.50 per report as a guest, $4.50 for members, or $6.75 for the pair, against $39.99 to $44.99 at retail. Trust the checkout total.
