The Arizona agent, in order

  1. Stage 1

    Know what Arizona requires

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

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

  2. Stage 2

    Who counts as an agent

    An Arizona resident, or a corporation or LLC formed in Arizona or authorized to do business there. The appointment takes effect only once the agent accepts it in writing. Legal basis: A.R.S. § 29-3115.

  3. Stage 3

    Use an office address that qualifies

    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.

    Each of our picks supplies a Arizona office address.

  4. Stage 4

    Be your own agent or hire one

    The agents we recommend cost $99 to $149 a year; serving yourself is for owners who qualify.

  5. Stage 5

    Name the agent in the filing

    A Arizona LLC that is just being formed names its agent on the Articles of Organization (Form L010). Any later switch is its own filing at the Arizona Corporation Commission.

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

  6. Stage 6

    Update when something changes

    Nothing is filed yearly here; the statutory agent is what you keep fresh.

Agent and state costs

Line itemReceiverSum
Registered agent serviceService$99 to $149 a year
Agent renewalService$99 to $149 a year
The state rows come from Arizona's published fee schedules (the pages we opened are listed under the table), and each service row comes from that company's own price. Across three years the state row counts the filing, the report in year two, the report in year three and any minimum tax.

Why the list runs this way

What decided it was work taken off your desk, which carries 32% of the score.

Arizona Registered Agent.co costs less, but coverage across states earned the better score.
