Who must register for Arizona TPT
You must register for an Arizona TPT license if your business has a tax nexus in Arizona. This usually applies when a business:
- Exceeds the economic nexus threshold of $100,000 in annual sales to Arizona customers in the current or previous calendar year, or;
- Has a physical presence in Arizona, such as an office, employee, warehouse, or inventory stored in the state.
Once you meet the threshold, you should register before making further taxable sales in Arizona. Businesses that exceeded the threshold in the previous calendar year must register for the entire current year.
If you're unsure whether your business has nexus, see the Arizona Transaction Privilege Tax Guide for a broader explanation of Arizona nexus rules.
How to register for Arizona TPT
Sellers can register online through AZTaxes.gov, the official portal for Arizona TPT registration operated by the Arizona Department of Revenue. A single AZTaxes.gov registration covers both the state TPT rate and any applicable city TPT — unlike most states, you do not need to register with individual Arizona cities.
Information you need before registering
Before applying for an Arizona TPT license, have this information ready:
- Your Social Security number (if registering as a sole proprietor with no employees)
- Your Employer Identification Number (EIN), if your business has one (required for corporations, partnerships, and most LLCs)
- North American Industry Classification System (NAICS) code for your primary business activity
- The date of your first sale in Arizona
- Your business locations in Arizona, if any (physical locations affect the combined TPT rate)
Registration steps
Follow these steps to register for an Arizona TPT license.
1. Create your online login
Set up your AZTaxes.gov account credentials.
- Choose a username and password
- Set up your security questions
- This login is used for all future TPT filings, payments, and account management
If you already have an AZTaxes.gov account (for another tax account), you can add a new TPT account to your existing login.
2. Provide your business locations
Enter your primary business address and any Arizona locations where you have physical presence.
- Remote sellers without an Arizona location will indicate they have no in-state locations
- If you have Arizona business locations, the city TPT rates for those locations will apply
- Arizona TPT uses origin-based sourcing for in-state sellers and destination-based for remote sellers
3. Pay the application fee
Arizona charges a $12 annual fee per business location for a standard TPT license. This fee is due at registration and again each year at renewal.
- The $12 fee covers the initial license period and your first year's coverage
- Payment is made online through AZTaxes.gov at the time of application
4. Submit your application
Review your entries and submit the application.
- You will receive an on-screen confirmation after submission
- A confirmation email is typically sent shortly after submission
5. Receive your Arizona TPT license
Once approved, you will receive:
- Your TPT license number (used for filing and payments)
- Your assigned filing frequency (monthly, quarterly, or annually, based on expected tax liability)
- License documentation showing your coverage of state and city TPT
What happens after registration
After registering, you must begin collecting Arizona TPT on taxable sales and file returns based on your assigned filing frequency. Your single AZTaxes.gov license covers both the state TPT and any city-level TPT, simplifying your ongoing compliance obligations.
Remember to renew your TPT license annually by January 1 each year ($12 per location) to keep your account in good standing.
