The walkthrough, stage by stage

  1. Stage 1

    Check whether Arizona wants your LLC to register

    If your LLC came from elsewhere and will operate in Arizona, you register first as a foreign LLC. What can go wrong without registering: until it registers, the LLC cannot sue in Arizona's courts (A.R.S. 29-3902(B)) existing deals still stand (A.R.S. 29-3902(C))

    Check it yourself: Official page: azcc.gov (viewed October 2026)

  2. Stage 2

    Get a certificate from your home state

    Attach certificate of existence or good standing, plus a certified copy of the organizational documents, no older than 60 days.

    Order this last so it is fresh when you file.

  3. Stage 3

    Find a statutory agent with an address in Arizona

    Every LLC must name a registered agent with an in-state street address. 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.

    Our ranking covers this role.

    Check it yourself: Official page: azleg.gov (viewed October 2026)

  4. Stage 4

    The paper to file is the Foreign Registration Statement

    Filing is registering, and the state charges $150 for it.

    Check it yourself: Official page: azcc.gov (viewed October 2026)

  5. Stage 5

    Keep the registration in force

    A foreign LLC files no repeating Arizona report.
