Arizona Car Sales Tax Calculator (2026)

• Arizona's state transaction privilege tax rate is 5.6%, and county and city taxes can be added to dealer sales.
• A trade-in allowance deducted before the sale is completed reduces the taxable amount, and a manufacturer's cash rebate assigned to the dealer is excluded.

Figured with Arizona's rules for a buyer in Phoenix, at its 3.5% local rate.

• Used car, no trade-in$1,609

  $18,000 price. Taxed on $18,000.

• New car with a trade-in$2,190

  $35,000 price, $10,000 trade-in. Taxed on $25,000. The trade-in saves $830.

• New car with a trade-in and a rebate$2,439

  $45,000 price, $15,000 trade-in, $2,000 rebate. Taxed on $28,000. The trade-in saves $1,245. The rebate saves $166.

These examples treat the agreed price as the taxable price. Where a state uses a book value instead, the tax can differ.

On a $30,000 car, tax runs from $2,220 in Buckeye to $2,816 in Flagstaff, a difference of $596 among the 15 cities we list.

Before trade-in, for a buyer living in each city. In some states the rate follows the dealer's location instead; see the rules above and our methodology. Rates from azdor.gov, checked Nov 6, 2026.

The calculator covers a car bought from a dealer. These rules apply to other ways of buying or bringing a car to Arizona.

Buying from a private seller

A car bought from a private party owes no Arizona use tax, because casual sales between private parties are not taxable. Bring the bill of sale or other proof of the private purchase when you register the car with MVD. (azdor.gov, checked Nov 10, 2026)

Moving to Arizona with your car

Arizona use tax does not apply to a car brought into the state by someone who was not an Arizona resident when buying it, if its first use was outside Arizona and it is not used to conduct a business in Arizona. (azleg.gov, checked Nov 10, 2026)

Buying outside Arizona

An Arizona resident who buys a car from an out-of-state dealer owes state and city use tax (5.6% state, no county tax) when registering it with MVD. Documented sales or excise tax paid in the other state reduces it, and you owe only the difference; tax paid in a foreign country earns no credit. (azdor.gov, checked Nov 10, 2026)

Active-duty military

ADOR states there are no use tax exemptions for vehicle purchases by military members: registering a car in Arizona counts as use and owes use tax even if the car has never entered the state. (azdor.gov, checked Nov 10, 2026)

Deadline to pay

The buyer must present the signed title or title transfer form and the fee to the Arizona Department of Transportation within 15 days after the transfer. (azleg.gov, checked Nov 10, 2026)

Paying late

If a car is driven on a highway without paying the registration or title transfer fee and the fee is not paid on time, MVD collects a penalty of $8 for the first month and $4 for each additional month, up to $100. (azleg.gov, checked Nov 10, 2026)
