These are the rules for a new car bought from a dealer. Used-car and private-sale rules can differ. How we check this data.
Utah charges 4.85% at the state level. Local taxes add more. That rate is higher than 15 states and lower than 35 states. County and city taxes may add to it, so check your local rate and enter the total in the calculator.
What to know in Utah
Utah's 4.85% state rate is joined by local taxes, so the combined rate is higher. Utah taxes the purchase price after subtracting any trade-in or rebate, so both lower the tax, and the calculator takes them off before figuring it.
Instead of an annual property tax on vehicles, Utah charges an age-based uniform fee with each registration. Budget for it separately from the purchase.
Does Utah tax your trade-in?
No. Utah only taxes the difference between the new car's price and your trade-in. On a $35,000 car with a $10,000 trade-in, you'd pay $1,212.50 in state tax instead of $1,697.50, a saving of $485.00. That saving is worth counting when you compare a dealer's trade-in offer with selling the car yourself.
Example: a car loan in Utah
A $35,000 car with $5,000 down, $1,500 in fees, and a 60-month loan at 6.5% APR ($1,697.50 state tax, rolled into the loan):
- Monthly payment: $649.55
- Amount financed: $33,198
- Total interest: $5,775
- Total cost of the car: $43,973

Rebates and fees
In Utah, a rebate lowers the taxable price, and the calculator takes it off before figuring the tax. Title, registration and dealer documentation fees vary, so ask for an itemized out-the-door price and put the fee total in the calculator.
