Arizona Sales Tax by Zip Code: Rates, Lookup, and Exemptions

Arizona sales tax by zip code runs from roughly 5.6% in unincorporated areas with no city tax to more than 9% in cities like Flagstaff and Tucson, because the total rate stacks a state layer, a county layer, and (usually) a city layer. The catch is that a zip code alone won’t reliably tell you which rate applies to a given address, since zip codes regularly cross city and county boundaries. For an exact answer, the Arizona Department of Revenue publishes a free lookup tool that returns the rate for any physical address in the state.1Arizona Department of Revenue. Tax Rate Table

Why Your Zip Code Isn’t Enough

Zip codes were drawn by the U.S. Postal Service to organize mail routes, not tax jurisdictions. A single five-digit zip code can straddle a city boundary, dip into unincorporated county land, or overlap with a special district. Two houses sharing zip code 85281 might owe different combined rates if one sits inside Tempe city limits and the other falls in an unincorporated pocket of Maricopa County.

The city layer alone can swing a rate by more than two percentage points, so treating a zip code as a stand-in for a jurisdiction is where most calculation mistakes start. A business that collects based on the zip code either shorts the state or overcharges customers. For a shopper trying to anticipate a receipt, the zip code gives you a reasonable ballpark and nothing more.

How to Look Up the Exact Rate for an Address

The Arizona Department of Revenue hosts a Rate Look-Up Tool on its Tax Rate Table page. You can enter a street address, a zip code, or use the map locator. The tool returns the state, county, and city rates together, along with the business classification codes.1Arizona Department of Revenue. Tax Rate Table A full street address gives the most precise result, because it pins the location to a single jurisdiction. A zip code search can return several possible rates when the zip code spans more than one city.

AZDOR also publishes a downloadable PDF listing every county and city rate in the state, organized by business classification. The table is refreshed monthly, though actual rate changes don’t necessarily happen every month.2Arizona Department of Revenue. Arizona State, County and City Transaction Privilege and Other Tax Rate Tables If you need to verify a rate for more than one address, the PDF is faster than running the lookup tool over and over.

How the Rate Is Built

Arizona doesn’t technically impose a “sales tax.” It levies a Transaction Privilege Tax (TPT), a tax on the business for the privilege of doing business in the state. The legal obligation falls on the vendor, not the buyer, though most businesses pass the cost along at the register.3Arizona Department of Revenue. Transaction Privilege Tax For a shopper, the practical effect is identical to a sales tax: a percentage added to the purchase.

Every taxable retail sale stacks three layers:

  • State rate: 5.6% on most retail sales. This includes a 5.0% base rate plus a 0.6% education surcharge originally approved by voters through Proposition 301.4Arizona Secretary of State. Proposition 301
  • County rate: each of Arizona’s 15 counties adds its own excise tax. Pima County adds 0.5%, Maricopa County adds 0.7%, and Coconino County adds 1.3%.2Arizona Department of Revenue. Arizona State, County and City Transaction Privilege and Other Tax Rate Tables
  • City rate: most of Arizona’s 91 incorporated cities and towns add a municipal tax, generally between under 2% and over 2.5%. Unincorporated areas have no city layer.5Arizona Legislature. Arizona Code 42-6002

AZDOR collects all three layers on behalf of the counties and cities, so businesses file a single return.6Arizona Legislature. Arizona Revised Statutes 42-6001

Combined Retail Rates in Major Arizona Cities

The rates below reflect the standard retail classification (business code 017) as of January 2026, the rate most shoppers see on tangible goods:

The spread between unincorporated Maricopa County and Flagstaff is over three percentage points. On a $1,000 purchase, that’s more than $30 in additional tax. Rates also differ by business classification. Transient lodging, construction contracting, restaurants, and amusement businesses each carry their own rate schedule, so the retail numbers above won’t apply to hotel stays or contractor invoices.9Arizona Legislature. Arizona Code 42-5010

What’s Exempt From Arizona TPT

Not every purchase carries TPT. The main exemptions a shopper will notice:

  • Prescription drugs and medical oxygen are exempt from state and city TPT when prescribed by a licensed medical professional.10Arizona Department of Revenue. Deduction Codes
  • Prescription eyeglasses and contact lenses are exempt at the state level.11Arizona Legislature. Arizona Revised Statutes 42-5061
  • Insulin, insulin syringes, and glucose test strips are exempt at the state level regardless of whether they’re prescribed.11Arizona Legislature. Arizona Revised Statutes 42-5061
  • Food for home consumption is exempt at the state level. Some Arizona cities still impose their own TPT on groceries, so whether you see a tax at the register depends on where you shop.

Professional and personal services are generally outside the TPT system. Hiring a lawyer, getting a haircut, or paying a plumber for labor alone doesn’t trigger retail TPT. If that plumber sells you a water heater, the tangible goods portion is taxable.11Arizona Legislature. Arizona Revised Statutes 42-5061

Online and Out-of-State Purchases

When you buy from an out-of-state seller who doesn’t collect Arizona TPT, you owe use tax on the purchase at the same 5.6% state rate. This covers online orders, catalog purchases, and goods brought back from a trip for use in Arizona.12Arizona Department of Revenue. Understanding Use Tax

The same exemptions apply: prescription drugs, most groceries, and casual sales between individuals are excluded. If you already paid sales tax in another state, Arizona generally gives you credit for that amount. Vehicles are treated separately. The Arizona Department of Transportation requires proof of tax payment at registration, and if you paid less than Arizona’s rate in the state of purchase, ADOT collects the difference when you register.12Arizona Department of Revenue.
