How to Form an LLC in Arizona

Steps to Form Your Arizona LLC

1. 1

   Choose Your LLC Name

   Must include "LLC" or "Limited Liability Company." Search the Arizona Corporation Commission website to confirm availability. Cannot be the same as an existing business in Arizona.

2. 2

   Designate a Registered Agent

   Must have a physical address in Arizona. Can be yourself, a friend, or a registered agent service ($50-300/year). This person receives legal documents on behalf of your LLC.

3. 3

   File Articles of Organization

   File with the Arizona Corporation Commission. Fee: $50. Processing: 5-10 business days. File online →

4. 4

   Get an EIN (Federal Tax ID)

   Free from the IRS. Takes 5 minutes online. Required for bank accounts, hiring, and tax filing. See our EIN guide →

5. 5

   Create an Operating Agreement

   Not required in all states but strongly recommended. Defines ownership percentages, profit distribution, management structure, and what happens if a member leaves.

   Open a Business Bank Account

   Keeps personal and business finances separate. Bring your EIN, Articles of Organization, and Operating Agreement to any bank. Required to maintain LLC liability protection.
