State sales tax
5.6% TPT plus county and city
Arizona charges 5.6% transaction privilege tax at state level, and counties and cities add their own rate on top, counties through their own excise tax and cities and towns under the Model City Tax Code, so the combined rate depends on the street address. Over-the-counter sales are sourced to the seller's business location under A.R.S. Sec. 42-5040, which means an in-store sale always takes your store's rate and never the customer's. Storeveu inherits the state rate for every Arizona store and takes a per-store override for the county and city layer, with no customer-address lookup anywhere in the tender path.
