What is the car sales tax rate in Arizona?

Arizona's state transaction privilege tax (TPT) on vehicle sales is 5.6%. Counties and cities add their own rates on top, so the combined rate in most areas is roughly 7% to 9% depending on where the dealer is located. The state portion is always 5.6%.

The Arizona Car Sales Tax Calculator estimates the one-time tax on a vehicle purchase in Arizona. The state transaction privilege tax (TPT) on vehicles is 5.6%, and your county and city add a local rate on top. Trade-in allowances are subtracted before tax, and private-party sales are generally exempt. The tool combines all of this into the tax owed at the MVD.

How it works

Tax applies to the price after any trade-in:

taxable amount = purchase price - trade-in allowance
state tax = taxable amount x 5.6%
local tax = taxable amount x (county + city rate)
total tax = taxable amount x (5.6% + local rate)
out the door = purchase price + total tax

For a private-party sale between individuals, no TPT is owed, so the tool reports $0 tax. For a dealer sale, the combined rate is generally the dealer’s location rate, not your home city’s.

Example and notes

A $30,000 dealer purchase with a $6,000 trade-in, in a city with a 2.7% local rate:

taxable: 30,000 - 6,000 = $24,000
state (5.6%):  $1,344.00
local (2.7%):  $648.00
total tax (8.3%): $1,992.00
out the door:  $31,992.00
  • Trade-in lowers the taxable base only at a licensed dealer.
  • Private-party used-car sales are generally exempt from TPT — you still pay VLT and title fees.
  • Local rates vary widely; check your dealer’s city/county rate. Runs in your browser.
