1. Phoenix — No General Business License (regulated activities only)

   The City of Phoenix does not have or issue a general business license. The Phoenix City Clerk's License Services section licenses only specific regulated activities (amusements, auctions, curb painters, escort bureaus, massage establishments, sexually oriented businesses, and vending). Most businesses need no Phoenix city license at all; if you make taxable sales you must hold an Arizona Transaction Privilege Tax (TPT) license from the Arizona Department of Revenue ($12 state license per location plus a $50 Phoenix city license fee, both administered by AZDOR).

3. Trade Name (DBA) Registration — Arizona Secretary of State

   If operating under a trade name, you may register it with the Arizona Secretary of State (online only). Registration is optional under Arizona law — it is not a legal prerequisite to doing business under the name — but it prevents another business from registering the same name and is commonly required by banks to open a business account. Registration lasts five years.
