Questions owners ask
Do I have to name a statutory agent?
Every LLC must name a registered agent with an in-state street address.
The law behind it: A.R.S. § 29-3115. looked up at azleg.gov in October 2026 to confirm
Who qualifies 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.
A qualifying owner can serve at no cost.
How much does an agent cost?
$99 to $149 a year with the services we recommend, which works out to $297 to $447 over three years.
Whichever agent you pick, the state's fees stay the same.
What does an agent do for the LLC?
The agent signs for lawsuits and state mail addressed to the LLC, using a street address in Arizona.
The last row is arithmetic, not a state figure: filing fee, plus the reports due in years two and three, plus a minimum tax where one applies. Open-ended costs stay out.
Still wondering?
Can I be my own agent?
You may, once you fit the state's rule. Plenty of owners still pay a service to keep a home address off the record.
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 do the picks cost over three years?
Arizona Registered Agent.co comes to $297; Mainstay Filing comes to $447; AZ Registered Agent.org comes to $297
Are the fees official?
Each state fee links to its official page, and each service price is read from the company's own site.
Do I have to use a service?
No. What the law asks for is a filing, and it does not say who has to send it.
Who should I ask first about a registered agent in Arizona?
Arizona Registered Agent.co comes first: a company that stays in Arizona pays $297 over three years. Next are Mainstay Filing and AZ Registered Agent.org.
