Arizona Reverse Sales Tax Calculator.

Arizona has an unusual sales tax system compared to most states — it's technically called the Transaction Privilege Tax (TPT), not a sales tax. While the practical effect is identical for consumers (you pay a percentage of the purchase price), the legal distinction is significant: the TPT is technically a tax on the privilege of doing business, paid by the seller rather than a tax on the buyer. In practice, sellers pass this cost on to consumers.

Arizona's state TPT rate is 5.6%, but with county and city add-ons, combined rates in most Arizona cities range from 7% to 11.2%. The Phoenix combined rate is approximately 8.6% (5.6% state + 0.7% Maricopa County + 2.3% Phoenix city). In Tucson, the combined rate reaches 8.7%. Some smaller Arizona cities have even higher combined rates.

Critically for Arizona businesses and consumers, the state recently centralized TPT administration through the Arizona Department of Revenue's AZTaxes portal. Before this reform, businesses had to file with the state and separately with each city. Now, single-location returns cover the state and most city taxes simultaneously, significantly reducing compliance burden.

Arizona exempts many categories from TPT: prescription drugs, most groceries (food for home consumption), most agricultural products, and qualifying medical equipment. Services are generally exempt from TPT in Arizona, though there are specific exceptions for services like transportation, telecommunications, and utilities.

For online sellers with nexus in Arizona, the economic nexus threshold is $100,000 in annual gross receipts. Arizona joined the nationwide trend of marketplace facilitator laws, meaning platforms like Amazon, Etsy, and eBay collect and remit TPT on behalf of Arizona sellers for sales through those platforms.
