How registration works in Arizona

  1. Move 1

    Decide if the LLC must register in Arizona

    LLCs from other states file a foreign registration to transact business in Arizona. What skipping it does: Its own claims have to wait until it registers (A.R.S. 29-3902(B)). Its contracts remain enforceable (A.R.S. 29-3902(C)).

  2. Move 2

    Pull the document from your home state

    Get certificate of existence or good standing, plus a certified copy of the organizational documents, dated within 60 days.

    Order it last so it is fresh when you file.

  3. Move 3

    Get a statutory agent with an Arizona address

    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.

    All of our picks act as the statutory agent.

    Where this comes from: Source page azleg.gov, October 2026

  4. Move 4

    Fill in and send the Foreign Registration Statement

    the Arizona Corporation Commission, Corporations Division takes the form and the $150 fee together.

    Where this comes from: Source page azcc.gov, October 2026

  5. Move 5

    Look at the recurring filing

    The state asks no annual report of foreign LLCs.

Costs, move by move

Move Pay to Figure
The registration move Paid to the state $150
A service, if you hire one Service $199 for year one
State fees for three years Paid to the state $150

We get the three-year state number by adding the filing, the reports due in years two and three and any yearly minimum tax. Service fees stay separate.

How we ordered the Arizona picks
