Arizona imposes a Transaction Privilege Tax (TPT) — not a traditional sales tax — of 5.6% at the state level, with local taxes bringing the combined rate up to 11.2%. You must register if your annual sales into Arizona exceed $100,000. SaaS and digital products are generally taxable under Arizona TPT.
Whether you sell software, physical goods, or digital content into the Grand Canyon State, this guide covers everything you need to know — how the TPT works, rates, taxability, nexus rules, registration, and filing.
What is the Transaction Privilege Tax in Arizona?
Arizona does not have a traditional sales tax. Instead, it levies a Transaction Privilege Tax (TPT) — a tax on the seller for the privilege of doing business in Arizona. The TPT is technically a gross receipts tax on certain business activities, not a tax on the buyer. However, most businesses pass the TPT through to customers, so it functions like a sales tax in practice.
The state TPT rate for the retail classification is 5.6%. Arizona cities and counties add their own TPT rates on top, bringing combined rates to as high as 11.2% in some areas.
Because Arizona TPT is an origin-based tax on the seller, in-state sellers charge based on their business location. Remote sellers without an Arizona location generally use destination-based rates based on the buyer's location.
What is taxable under Arizona TPT?
Arizona TPT applies to the gross receipts of businesses engaged in taxable activities. There are different TPT "classifications" (categories) for different types of transactions — retail, restaurants, hotels, utilities, and so on. For most sellers, the retail classification applies.
Digital products and SaaS taxability in Arizona
Arizona is one of the states that taxes digital goods and SaaS:
- SaaS: Taxable. Arizona treats software delivered electronically, including cloud-based software accessed remotely, as subject to TPT.
- Downloaded software: Taxable as electronically transferred tangible personal property.
- Digital products (e-books, digital audio, digital video): Taxable under Arizona TPT.
- Streaming services: Generally taxable.
This broad taxability of digital goods means Arizona compliance for software businesses is clear: if you sell SaaS or digital products to Arizona customers, you should collect TPT.
TPT on shipping charges in Arizona
Shipping and delivery charges in Arizona are generally taxable when they are charged as part of the sale of a taxable item. If the underlying item is exempt, the separately stated shipping charge may also be exempt.
Exemptions and deductions in Arizona
Rather than traditional exemptions, Arizona uses a system of deductions and non-taxable categories within each TPT classification. Key non-taxable transactions include:
- Sales for resale, with a valid Arizona exemption certificate (Form 5000)
- Sales of most prescription drugs and medical equipment
- Sales to qualifying exempt organizations (government entities, certain nonprofits)
- Agricultural machinery and equipment
- Manufacturing machinery and equipment used directly in production
To claim a resale deduction, the buyer must provide a completed Transaction Privilege Tax Exemption Certificate (Form 5000) at the time of purchase. See the Arizona Department of Revenue for the complete list of exemptions.
Who must collect TPT in Arizona?
Nexus determines whether your business must register for Arizona TPT. If you have nexus, you must register, collect, and remit TPT on taxable Arizona sales.
Economic nexus in Arizona
You have economic nexus in Arizona if your sales into the state exceed $100,000 in the current or previous calendar year. Once you meet this threshold, you must register for TPT.
To learn more, see the Ultimate Guide to US Economic Nexus.
Physical nexus in Arizona
| Type of nexus | Definition |
|---|---|
| Physical presence | Having a store, office, warehouse, distribution center, or other business location in Arizona. |
| Employees or representatives | Having employees, agents, or contractors performing work on your behalf in Arizona. |
| Inventory | Storing inventory in Arizona, including through a third-party warehouse or fulfillment center. |
| Leasing property | Owning or leasing real or tangible personal property within Arizona. |
| Solicitation | Having sales representatives or agents solicit orders in Arizona. |
Marketplace facilitator rules in Arizona
Marketplace facilitators with nexus in Arizona are required to collect and remit TPT on behalf of their marketplace sellers. Your marketplace sales do not count toward your $100,000 economic nexus threshold when a marketplace facilitator handles the tax on those transactions.
See our state-by-state guide to marketplace facilitator laws for more information.
Transaction Privilege Tax rates in Arizona
Arizona has a 5.6% state retail TPT rate. Cities and counties add their own rates, bringing combined rates to a maximum of 11.2% in some areas.

| State TPT | The statewide retail TPT rate is 5.6%. |
| County tax | Counties levy their own TPT rates, administered through the Arizona Department of Revenue. |

How to calculate TPT in Arizona
Apply the combined rate (state + county + city) at the buyer's location to the gross receipts from each taxable sale.
Example: You sell a $100 SaaS subscription to a business in Phoenix (8.6% combined rate). TPT is $8.60, making the total $108.60.
Example: You sell a $200 physical item to a customer in Tucson (8.7% combined rate). TPT is $17.40, making the total $217.40.

How to register for an Arizona TPT license
If your business has nexus in Arizona, register before collecting TPT. Register online through AZTaxes.gov, the Arizona Department of Revenue's official portal. A single TPT license covers both the state and city-level taxes, which simplifies the registration process significantly compared to states where you must register separately with each city.
For a step-by-step walkthrough of the registration process, see the Arizona Transaction Privilege Tax Registration Guide.
Filing and payment in Arizona
How often do you file TPT in Arizona?
Arizona assigns your filing frequency at registration based on your expected annual tax liability — monthly, quarterly, or annually.
When are Arizona TPT returns due?
Returns are due on the 20th of the month following the close of the reporting period. If the 20th falls on a weekend or holiday, the return is due the next business day.
How to file and pay Arizona TPT
File and pay online through AZTaxes.gov. Arizona requires electronic filing for most sellers. Zero returns are required for each assigned period even if you had no taxable transactions.
For step-by-step filing instructions, see the Arizona Transaction Privilege Tax Filing Guide.
Penalties and compliance risks in Arizona
Late filing or payment triggers penalties and interest. Common compliance risks in Arizona:
- Not registering when you cross the $100,000 threshold — economic nexus applies, and late registration creates back-tax liability.
- Applying the wrong combined rate — Arizona's overlapping state, county, and city rates make it easy to undercollect if you apply only the state rate.
- Treating TPT like a traditional sales tax — the TPT is technically a seller's tax, not a buyer's tax. While most businesses pass it through to customers, understanding this distinction matters for exemption certificates and deductions.
For penalty details, see the Arizona Department of Revenue.
