How to Form an LLC in Arizona

Step 1: Choose and check your LLC name

Arizona LLC names must include “Limited Liability Company,” “LLC,” or “L.L.C.” Search availability via the Arizona Secretary of State business search.

Step 2: Appoint a registered agent

Your Arizona LLC needs a registered agent with a physical street address in the state who is available during normal business hours to receive service of process. You can serve as your own agent if you reside in Arizona.

Step 3: File Articles of Organization

File Articles of Organization with the Arizona Secretary of State. The filing fee is $50. Online filing is available and is typically faster than mail.

Step 4: Get an EIN from the IRS

Apply for a free Employer Identification Number through IRS.gov. EINs issue immediately for online applicants with a US Social Security Number or ITIN.

Step 5: Draft an Operating Agreement

Arizona does not require LLCs to file an Operating Agreement, but having one is essential to preserve liability protection — especially for single-member LLCs.

Step 6: Comply with annual obligations

Arizona requires an annual report (or equivalent) costing $0 on a annual basis. Set a calendar reminder; the late-filing penalty in most states is significant.

Step 7: Local licensing and permits

Check city and county requirements wherever your LLC operates in Arizona. Many municipalities require a local business license even for online businesses.

Arizona-specific notes

Arizona is filed with the Arizona Corporation Commission (not the Secretary of State). Most counties require publication of formation notice in a newspaper for three consecutive weeks; Maricopa and Pima counties are exempt. Arizona has no annual report requirement for LLCs.
