Arizona TPT (sales tax): rates, nexus & AZTaxes.gov filing
Arizona doesn't have a sales tax — it has the Transaction Privilege Tax (TPT), a tax on the seller for the privilege of doing business. That legal difference, plus origin sourcing and taxable SaaS, makes Arizona behave differently from almost every other state. The upside: city TPT is collected centrally, so you file one combined return.
The Arizona numbers at a glance

| State base rate | 5.6% |
| Combined rate range | 5.6% – 11.2% with county + city TPT |
| Economic nexus threshold | $100,000 in AZ gross sales (sales-only, no transaction count) |
| SaaS taxable? | Yes — taxed as rental of tangible personal property |
| Sourcing rule | Origin for in-state sales; destination for remote sellers |
| City TPT | Collected centrally by the state — one combined return |
TPT is a seller's tax — why that matters
The most important thing to understand about Arizona is that TPT is legally imposed on the seller, not the buyer. In a normal sales-tax state you are a collection agent; in Arizona you owe the tax on your gross receipts whether or not you separately charge the customer.
- You may pass TPT through to customers as a line item (almost everyone does), but the liability is yours.
- If you fail to collect, you still owe the state — there is no “the customer didn't pay” defense.
- TPT is reported on your gross receipts under a business classification (retail, restaurant, etc.), each with its own rules.
Origin sourcing and taxable SaaS — two Arizona surprises
Two things consistently catch businesses out in Arizona:
- Origin sourcing.For in-state sales, the rate generally keys to your business location rather than the customer's — the reverse of destination states. A single Arizona storefront charges one consistent in-state rate.
- Taxable SaaS. Arizona taxes remotely-accessed software as a rental of tangible personal property. If you sell SaaS into Arizona, those subscriptions are taxable — a rare position most states do not take.

How HelloBooks does this
HelloBooks handles every Arizona-specific quirk — seller-liable TPT on gross receipts, origin sourcing for in-state sales, taxable SaaS, the single combined state + county + city return on AZTaxes.gov, and use tax on out-of-state purchases.
- 1
Get a TPT license from the Arizona DOR
Apply for a Transaction Privilege Tax license on AZTaxes.gov — a single license covers state, county, and all city TPT. You'll be assigned a filing frequency by liability. Enter the TPT license number and frequency into HelloBooks. Remember: as the seller you are liable for TPT even if you don't separately bill it to the customer.
- 2
Tag SaaS and software as taxable
Arizona taxes SaaS and remotely-accessed software as a rental of tangible personal property — unlike most states. Tag those lines to Arizona customers as taxable in the item master so you collect TPT where it's due and don't create an under-collection liability.
- 3
Apply origin sourcing for in-state sales
On Pro and above, HelloBooks computes the rate through Avalara AvaTax — for in-state Arizona sales it sources to your business location (state 5.6% + county + city), and for remote sales into Arizona it sources to the buyer's address, up to the ~11.2% combined maximum. On the Free Plan you apply manual per-state rates.
- 4
File one combined TPT return on AZTaxes.gov
Because Arizona consolidated city collection, HelloBooks builds a single TPT return draft (TPT-EZ / TPT-2) covering state, county, and city tax — no separate city filings. Review the working paper, file on AZTaxes.gov, and mark paid in HelloBooks.
- 5
Reconcile use tax on out-of-state purchases
Arizona has a parallel use tax on goods bought from out-of-state vendors that did not charge Arizona tax. HelloBooks tracks those vendor bills, computes the use tax owed, and rolls it into the next return — keeping you audit-ready on the line most businesses forget.
Frequently asked questions
What is the Arizona Transaction Privilege Tax (TPT)?
Arizona does not technically have a sales tax — it has the Transaction Privilege Tax (TPT), a tax on the privilege of doing business in the state. The legal difference matters: TPT is imposed on the seller, not the buyer. The seller is liable for the tax whether or not they pass it on to the customer, so under-collecting still leaves you owing the state.
What is the Arizona TPT rate?
The state TPT rate is 5.6%. With county and city rates stacked on top, combined rates reach roughly 11.2% depending on the location. Arizona cities can add substantial local rates, so the combined figure varies widely between, say, a Phoenix sale and a sale in a small county.
What is the Arizona economic nexus threshold?
$100,000 in gross sales into Arizona during the previous or current calendar year — a sales-only test with no transaction-count alternative. Crossing it requires a TPT license from the Arizona Department of Revenue and collection on subsequent sales.
Is Arizona origin-sourced or destination-sourced?
For in-state sales, Arizona is origin-sourced — the rate is generally determined by the seller's business location, not the buyer's. This is the opposite of most states. For remote sellers shipping into Arizona from out of state, destination sourcing applies. Origin sourcing simplifies rate logic for a single-location Arizona seller but trips up businesses used to destination-based states.
Does Arizona tax SaaS and software?
Yes. Arizona is one of the states that taxes SaaS — it treats remotely-accessed software as a taxable 'rental of tangible personal property' under the TPT regime. This is unusual and catches many software sellers off guard, since most states exempt remote-access SaaS. Tag SaaS lines to Arizona customers as taxable.
How do Arizona's home-rule cities work?
Arizona has 'program cities' and 'non-program' home-rule cities, but unlike Colorado, Arizona consolidated city TPT collection through the state. Since 2017 the Arizona Department of Revenue administers and collects city TPT for all cities through a single license and the AZTaxes.gov portal — so you file one combined return covering state, county, and city tax rather than separate city filings.
How does the Arizona marketplace facilitator law work?
Marketplace facilitators (Amazon, Etsy, eBay, Walmart) that exceed the threshold collect and remit Arizona TPT on third-party seller transactions. You still track marketplace sales toward your own nexus, but the facilitator remits on those orders; you remit only on your direct sales.
