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.
Arizona charges 5.6% at the state level. Transaction privilege tax; county and city rates add more. That rate is higher than 25 states and lower than 25 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 Arizona
Arizona's tax on car sales is a transaction privilege tax: legally it's owed by the dealer, who passes it on to you in the price. The state portion is 5.6%, and county and city rates are added on top, so the total you pay is higher than the state rate alone.
Arizona's ruling on dealer sales taxes the price after your trade-in, so trading in at the dealer cuts the tax. When you weigh the dealer's trade-in offer against a private sale, count that tax saving as part of what the dealer is paying you.
Does Arizona tax your trade-in?
No. Arizona 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 $1,400.00 in state tax instead of $1,960.00, a saving of $560.00. That saving is worth counting when you compare a dealer's trade-in offer with selling the car yourself.
Example: a car loan in Arizona
A $35,000 car with $5,000 down, $1,500 in fees, and a 60-month loan at 6.5% APR ($1,960.00 state tax, rolled into the loan):
- Monthly payment: $654.68
- Amount financed: $33,460
- Total interest: $5,821
- Total cost of the car: $44,281

Rebates and fees
The calculator charges tax on the price before any manufacturer rebate. Ask the dealer how Arizona treats your specific rebate. Title, registration and dealer documentation fees vary, so ask for an itemized out-the-door price and put the fee total in the calculator.
