How much is sales tax in Arizona?
Arizona's base state rate is 5.6%, but local taxes layer on top, driving combined rates up to 13.43% in Kayenta and surrounding areas. The average combined rate across all 566 jurisdictions is 8.24%, which represents what a typical mid-range transaction will face. This multi-tiered system means you need to know your exact address to calculate the true tax burden.
Arizona's local tax landscape varies significantly by city and county, creating what amounts to a patchwork of rates. A shopping center a few blocks away might fall into a different taxing jurisdiction with a meaningfully different combined rate. Address lookup is the only way to be certain you're applying the correct percentage.
What's taxed and what's exempt in Arizona
Groceries are exempt in Arizona—a consumer benefit not available in every state. Clothing, on the other hand, is fully taxable at your location's combined state and local rate.
SaaS and digital software are taxable in Arizona, setting it apart from many states that exempt these categories. Prescription medicine is exempt. Restaurant and prepared food are also taxable. If a category isn't clearly listed, verify it rather than guessing.
Do you have to collect Arizona sales tax? (Economic nexus)
Like most states after the 2018 Wayfair decision, Arizona requires out-of-state sellers to register and collect once their sales into the state cross an economic-nexus threshold. That line is commonly around $100,000 of sales into Arizona per year, and some states also count a number of separate transactions — but the exact figure, and whether the transaction count still applies, change from time to time. Confirm Arizona's current threshold before you rely on it.
If you sell into Arizona from out of state, the practical question is whether you've crossed that line. Watching your sales into each state is how you know when you're on the hook — and it's the kind of thing that's easy to miss until a notice shows up.

How to calculate Arizona sales tax
The math itself is simple: multiply the taxable price by the combined rate for the buyer's location. A $100 order at 8.239% means about $8.24 in tax. The hard part is getting the right rate for every address, keeping it current as rates change, and doing it fast enough to run inside a checkout.
