Arizona vehicle license tax and car buying fees

How the vehicle license tax is figured

The vehicle license tax replaces a property tax on cars. Under A.R.S. § 28-5801, the assessed value starts at 60% of the manufacturer’s base retail price, and the tax is $2.80 per $100 of that value in the first twelve months. Each later year the value drops by 16.25% and the rate becomes $2.89 per $100, with a minimum of $10. Because the base is the original sticker price, buying a used car cheaply does not reset the tax: the MVD uses the car’s original price and age. That is why the calculator asks for the MSRP when you have it.

Sales tax at three levels, with city tiers

Arizona has no sales tax in the usual sense but a transaction privilege tax that the dealer pays and passes on. The Department of Revenue rate table for October 2026 combines the 5.6% state rate with county rates from 0% in Mohave County to 1.3% in Coconino County, then adds the city rate. Several cities cut their rate on expensive items: Phoenix charges 2% instead of 2.8% on the portion of a single item above $14,338, Apache Junction and Casa Grande do the same above lower thresholds. A car bought from a private seller owes no transaction privilege or use tax at all, so the buyer of an $18,000 used car pays only $120 at the MVD, before any emissions test.

Emissions tests in Phoenix and Tucson

Only the Phoenix and Tucson areas test emissions. A new car is exempt until its sixth registration year; after that, most cars around Phoenix are tested every two years and most around Tucson every year, at $16.15 for the standard OBD test. Electric cars are exempt and also skip the $1.50 air quality fee. Arizona has no separate EV registration fee in 2026, unlike its neighbor California, where electric cars pay a road improvement fee every year.

What sets Arizona apart

• The yearly vehicle license tax is levied on 60% of the manufacturer’s base retail price at $2.80 per $100 in the first year, then on a value that drops 16.25% a year at $2.89 per $100 (A.R.S. § 28-5801).
• The vehicle license tax is never less than $10 a year (A.R.S. § 28-5801(B)(3)).
• Registration costs $8 and a certificate of title $4, among the lowest flat fees in the country (A.R.S. § 28-2003).
• Every registration adds a $1.50 air quality fee, except for electrically powered vehicles (A.R.S. § 49-551).
• The highway safety fee once collected with registration ended for registrations after June 30, 2021 (A.R.S. § 28-2007).
• A dealer sale pays the 5.6% state rate plus a county excise of up to 1.3% and a city rate; Phoenix taxes the portion of a single item above $14,338 at 2% instead of 2.8% (Arizona Department of Revenue).
• The value of a trade-in is excluded from the taxed amount when it is deducted from the sales price (A.R.S. § 42-5001).
• A reasonable doc fee shown separately on the invoice is not subject to transaction privilege tax (Arizona Department of Revenue).
• Cars in the Phoenix and Tucson areas need an emissions test from their sixth registration year, at $16.15 for the OBD test (ADEQ myAZcar).
• Electrically powered vehicles are exempt from the emissions test (A.R.S. § 49-542).

What the Arizona calculation cannot know

• The vehicle license tax is based on the manufacturer’s base retail price, not the price paid; without an MSRP the engine uses the price, which misstates the tax on a used car. Age is counted from the model year, while the law counts twelve-month periods from the first registration.
• Electric and other alternative-fuel vehicles first registered in Arizona before 2023 kept a reduced vehicle license tax ($4 per $100 of 1% or 20% of the base price, minimum $5); the engine applies the regular rate to every vehicle.
• Some cities (Glendale, Avondale, Goodyear, Buckeye, Marana, Kingman, Safford) list a lower rate for a “single item over” a threshold; the rate table does not say how it applies to a vehicle, so the city tax is shown as a range between the two rates.
• Only the main cities and every county’s unincorporated area are listed; for another city, type its combined county and city rate.
• The emissions test is applied to Maricopa County cities (area A) and Tucson-area cities in Pima County (area B); parts of Pinal and Yavapai counties near Phoenix are also in area A. Check the ADEQ map for your address.
• Arizona sets no cap on the dealer documentation fee; type the dealer’s figure.
