Arizona does not issue a single vendor’s license. To sell goods in the state, you register with the Arizona Department of Revenue for a Transaction Privilege Tax (TPT) license, which costs $12, and then add whatever business license the city or county you sell in requires on top of that. Apply online and you’ll have your TPT number the same day.
What the TPT License Is and Who Needs One
The TPT license is Arizona’s version of a sales tax registration, with one legal twist that matters: the transaction privilege tax is imposed on the vendor for the privilege of doing business in Arizona, not on the buyer. You are legally on the hook for the tax, even though most vendors pass the cost through to customers as a line on the receipt.
One license covers all layers of tax you collect. The state retail rate is 5.6%, and counties and cities add their own on top, so the combined rate depends on where the sale happens.1Arizona Department of Revenue. Transaction Privilege and Other Tax Rate Tables – January 2026 The TPT license registers you with ADOR to collect and remit the combined state, county, and city taxes for your business activity and location.
During the application you’ll pick a three-digit business classification code: 017 for standard retail, 011 for restaurants and bars, 015 for contracting, and so on. The code sets which rules and rates apply to your sales.2Arizona Department of Revenue. Business Class Codes
Out-of-state sellers need the license too once their gross sales into Arizona hit $100,000 in the current or prior calendar year.3Arizona Department of Revenue. Economic Threshold Even if everything you sell is exempt from TPT, you still need to register and file returns showing zero tax owed.
How to Apply for a TPT License
The application is called the Arizona Joint Tax Application, form JT-1. It’s “joint” because the same form registers you with the Department of Economic Security for employer withholding and unemployment insurance if you have employees.4Arizona Department of Revenue. Joint Tax Application for a TPT License
Before you start, pull together:
- Your federal Employer Identification Number (EIN). Sole proprietors with no employees can use a Social Security Number instead.5Arizona Department of Revenue. Arizona Joint Tax Application JT-1
- The three-digit business classification code for your activity.
- The physical address of every location where you’ll do business, along with the matching region and location codes.
- Your business structure (sole proprietorship, LLC, partnership, or corporation).
You have three ways to file. Online at AZTaxes.gov is fastest: create an account, work through the business registration, enter your location codes, and pay the $12 fee at checkout. Your TPT license number is issued the same day, and the physical certificate arrives by mail within seven to ten business days.6Arizona Department of Revenue. Applying for a TPT License By mail, send the completed JT-1 and payment to the Arizona Department of Revenue, PO Box 29032, Phoenix, AZ 85038-9032, and expect about two weeks.5Arizona Department of Revenue. Arizona Joint Tax Application JT-1 In person at an ADOR office, you can walk out with the license the same day.
Fees, Renewal, and Expiration
The initial state TPT license fee is $12, set by statute. It’s a one-time fee per license. The license is valid only through the calendar year it’s issued in, and you must renew for the next year. There is no fee to renew the state TPT license.7Arizona Legislature. Arizona Revised Statutes 42-5005 – Transaction Privilege Tax and Municipal Privilege Tax Licenses
The municipal privilege tax license is different. It also expires at year-end, and renewal runs up to $50 depending on the city. That fee is due January 1 and becomes delinquent if it isn’t received by the last business day of January.7Arizona Legislature. Arizona Revised Statutes 42-5005 – Transaction Privilege Tax and Municipal Privilege Tax Licenses Miss that window and you’re operating without a valid license.
City and County Business Licenses
This is the step first-time vendors miss most. Arizona has no statewide business license, and the state TPT license does not replace local ones.8Arizona Commerce Authority. Business Licensing Most cities and towns issue their own, and many require anyone conducting business inside city limits to carry both a city business license and a city privilege tax license, not just vendors physically based there.9Arizona Department of Revenue. Licensing and Renewal Requirements
Fees, forms, and timelines vary by municipality, so contact the clerk’s office in every city where you plan to sell. If you only work occasional events like swap meets or craft fairs, ask about temporary event permits; many cities require one even for a single weekend.
Home-Based Vendors
Arizona statute limits how far counties can go in regulating home-based businesses. A licensed home-based vendor can sell goods from the property, display a temporary commercial sign up to 24 by 24 inches during business hours, and employ up to two non-household members in addition to residents and immediate family.10Arizona Legislature. Arizona Revised Statutes 11-820 – Restriction on Regulation; Home-Based Businesses; Exception Counties can still set reasonable operating requirements, and the statute doesn’t override HOA covenants or similar private restrictions. If you’re inside city limits rather than on unincorporated county land, check the city’s home occupation rules too.
Food and Mobile Food Vendors
If you sell food, add a county health permit to the stack. The county health department where the food is prepared or served has to verify your operation meets food safety and sanitation standards before you can sell.
Mobile units like food trucks go through their own permitting path in the county where their commissary (the approved commercial kitchen used for prep and storage) is located. Expect to submit a menu, a commissary agreement, a toilet-use agreement, photos of the unit, and a route sheet.11Maricopa County. Mobile Food Establishments Once you’re permitted, state law gives you some protection: a city can’t require a special permit that isn’t also required of other mobile vendors in the same zoning district, and it can’t force a new fire inspection if you passed one in another Arizona city within the previous twelve months.12Arizona Legislature. Arizona Revised Statutes 9-485.01 – Mobile Food Vendors; Mobile Food Units; Operation
Filing Returns Once You’re Licensed
After registration, ADOR assigns a filing frequency based on your estimated annual combined tax liability:13Arizona Department of Revenue. TPT Filing Frequency
- Annual filing if you expect less than $2,000 in tax.
- Quarterly between $2,000 and $8,000.
- Monthly above $8,000.
- Seasonal if you operate eight months or fewer per year.
Returns are due on the 20th of the month after the end of your tax period. Electronic filers get a grace period through the last business day of that month; paper filers have until the second-to-last business day.13Arizona Department of Revenue. TPT Filing Frequency
Penalties for Operating Without a License
Skipping the TPT license is not treated as a paperwork oversight. Arizona law bars you from engaging in or continuing in business before obtaining the license, and violating the licensing statute is a Class 3 misdemeanor.7Arizona Legislature. Arizona Revised Statutes 42-5005 – Transaction Privilege Tax and Municipal Privilege Tax Licenses That is potential criminal liability, not just a fine.
Tax penalties stack on their own. A late return triggers 5% of the tax owed per month or partial month, capped at 25%. Failing to pay what you owe adds another 10% on the unpaid amount. When both apply to the same period, the combined total is capped at 25% of the tax due, and interest accrues on top at the federal short-term rate plus three percentage points. If ADOR finds fraud or evasion, the penalty rises to 50% of the amount owed.14Arizona Department of Revenue. Interest and Civil Penalties At $12, the state license is one of the cheapest compliance costs a new vendor will ever face.
