Starting an LLC in Arizona: what you should know first

Filing a Arizona LLC costs $50. There is no annual report afterwards. Our pick is Mainstay Filing; $647 covers three years.

By kind of owner

Side hustle: Quiet-year cost: $199 in year 2 with Mainstay Filing, no state report.
Online business: Required registered agent. The address has to be a place of business or residence in Arizona with a street address. A P.O. box can be listed only as a separate Arizona mailing address.
Startup: Filing: Articles of Organization (L010) with the Arizona Corporation Commission. Write the operating agreement before you open the bank account.
First-time owner: Nothing to file yearly.

Publication: a notice runs three times within 60 days unless the statutory agent is in a county of more than 800,000 people, where the Commission posts it instead.
