Straight replies
Is naming a statutory agent a legal duty?
Every LLC must name a registered agent with an in-state street address.
The rule comes from A.R.S. § 29-3115. azleg.gov, current in October 2026 per the state
Can I pick anyone?
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.
An owner who qualifies can serve at no cost.
What do agents run?
Yearly prices start at $99 to $149; the three-year total is $297 to $447.
Naming a different agent does not change any state fee.
What is the agent's function?
When a lawsuit or state letter reaches the LLC in Arizona, the agent is the one who receives it.
Look for an agent who passes documents along promptly, so no deadline slips. Read: service of process
What recurs apart from the agent?
Nothing recurs on the report side: Arizona asks for none.
What put the top pick on top?
It comes down to paperwork covered, where Mainstay Filing does best.
The two heavy tests are three-year price (36%) and paperwork covered (29%); three lighter tests follow.
Where a service can be used counts in our scoring, and one pick works everywhere.
Every figure above links to its official source; the last line is our own addition of the filing, two reports and any minimum tax, with variable costs such as publication left out.
A few more
May I name myself as agent?
In most cases, yes. Check who qualifies and which address counts, then you can do it yourself.
What address does an agent need?
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.
What does each pick cost across three years?
$447 for Mainstay Filing, $297 for AZ Registered Agent.org, $297 for Arizona Registered Agent.co
How do you know these fees?
State side: Arizona's published fee schedules and forms. Service side: the prices each company lists.
Must I hire a service?
No. What you pay a service covers the labor and the agent role, not anything the state demands.
What is the best registered agent for Arizona?
Mainstay Filing first: the $149 yearly price follows the company to any state it adds. AZ Registered Agent.org and Arizona Registered Agent.co follow.
