How Utah works

  • Utah taxes a car at the rate of the dealership's location, not where you live: 4.85% state tax plus county, city and transit taxes, which comes to 6.35% to 8.45% across Utah ZIP codes in October 2026. The dealer collects it and sends it to the Tax Commission, so you pay no sales tax to the DMV on a dealer purchase. This estimate uses your ZIP's rate; if the dealer is elsewhere, the dealer's rate applies.
  • A car is exempt from the resort communities tax, the correctional facility tax and the capital city revitalization tax. The rate used here already leaves them out, so it can be a point or more below the combined rate on the Tax Commission's chart. Salt Lake City's chart rate is 8.45%; a car there is taxed at 7.45%.
  • Your trade-in reduces the taxable amount, with no dollar cap, on new and used cars. It has to be part of the same transaction and written into the same contract. Manufacturer rebates reduce it too, if they are separately stated on the contract, and so do dealer discounts.
  • The doc fee is taxed. Utah sets no cap on it. The dealer must post a sign saying the fee is not set or required by the state, and list it apart from government fees.
  • Service contracts, extended warranties, prepaid maintenance plans and dealer accessories are taxed. GAP coverage is not. The calculator taxes everything entered as F&I products, so it overstates the tax a little if you add GAP.
  • At the sale: the dealer normally collects the title, registration, age-based fee and plates, issues a 45-day temporary permit, and files the paperwork with the DMV within 45 days. You can register the car yourself instead. Then the dealer must give you the title within 48 hours and a report of sale showing the tax was collected.
  • The age-based uniform fee is Utah's substitute for property tax on a car: $150 in the first three model years, then $110, $80, $50 and $10. Registration does not transfer from the seller, so a used car is registered again, and the fee charged again, in your name.
  • State registration fees are indexed to inflation every January 1, and a $0.50 charge is added on January 1, 2027. Plates and postage are an estimate. The DMV's fee estimator gives the exact figure for your car.

My price already includes…

Federal law says a dealer's advertised price should include every fee the dealer charges, so where we've checked a state's rules we tick the ones that apply there for you. Untick any your price doesn't cover, so nothing is missed or counted twice.

What a Utah advertised price has to include

Utah's advertising rule requires a dealer's advertised price to include freight, destination, dealer preparation, dealer handling and any non-optional items installed, but lets the dealer leave out the dealer documentary service fee and a temporary permit fee. The FTC expects more: every fee the dealer requires, the documentary fee included, belongs in the advertised price, so only government charges like sales tax, title and registration can be added on top. That still isn't your out-the-door number; the calculator above adds the rest for your ZIP.

Federal law comes first

The FTC requires a dealer's advertised price to include every fee the dealer charges. Only charges the government requires you to pay, like tax, title and registration, can be left out. Where a state's rules let a dealer leave a fee out, the dealer still has to follow the federal rule, so the fee goes in. The FTC says a state's doc-fee rules can add disclosures, but they don't change the price that has to be advertised. Read the FTC's guidance.

Utah's rule and the FTC conflict on the documentary fee

Utah's advertising rule says an advertised price does not have to include the dealer documentary service fee or a temporary permit fee, and Utah law lets the dealer add both on top of the negotiated price. The FTC expects every fee a dealer requires to be in the advertised price, so the two conflict. Until regulators or the courts settle it, you may see Utah ads that leave the fee out. Ask whether a price includes it, and get the out-the-door price in writing.

What the FTC expects in the advertised price

  • The documentary fee (Utah sets no cap), whatever the dealer calls it
  • Freight (destination) and dealer preparation or handling charges
  • Non-optional items installed on the car
  • The temporary permit fee, if the dealer passes it on
  • An emissions test charge, if the dealer passes it on

Can still be added on top

  • Sales tax: 4.85% state plus county, city and transit taxes at the dealership's location
  • The $6 title fee, registration fees, the age-based uniform fee, plates and county fees
  • The $1-a-tire waste tire recycling fee
  • Optional products you choose to buy, such as a service contract or GAP coverage

Utah OTD questions, answered

Does a trade-in reduce sales tax in Utah?

Yes — Utah taxes the difference: your trade-in's value is subtracted before tax is computed.

Are manufacturer rebates taxed in Utah?

No — rebates passed to you are treated like a cash discount and reduce the taxable amount.

Is the doc fee capped in Utah?

No — doc fees are uncapped in Utah; buyers report a typical $447.00. It's negotiable as part of your total OTD.

What does a Utah dealer's advertised price have to include?

Under Utah's rule: freight, destination, dealer preparation, dealer handling and any non-optional items installed. The rule lets a dealer leave out the documentary fee, a temporary permit fee, optional items and government taxes and fees. The FTC expects every fee the dealer requires, the documentary fee included, to be in the price, so the two conflict. Only sales tax, title, registration and other government charges belong on top.

Is there a limit on a Utah dealer's doc fee?

No. Utah sets no cap and no amount. The dealer must post a sign saying the fee is not state-mandated and list it separately, and it is taxed. CarEdge's 2026 quotes average about $450, from under $100 to nearly $1,000.

Do I pay sales tax at the dealership in Utah?

Yes. The dealer collects it at the rate where the dealership is and sends it to the Tax Commission. You pay no sales tax to the DMV on a dealer purchase. You pay the title, registration and age-based fees, normally through the dealer, which files them for you.

What else can a Utah dealer charge on top of the price?

Only a documentary fee, a temporary permit fee, title and registration fees, sales tax and other government charges. Utah Code 41-3-211 bars any other required fee on top of the negotiated price. Products you choose to buy are separate.
