The questions that matter
Does the state make me have a statutory agent?
Every LLC must name a registered agent with an in-state street address.
Statute: A.R.S. § 29-3115. azleg.gov, confirmed October 2026, if you don't believe us
Who can be the 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 for free.
What does an agent cost?
You're looking at $99 to $149 a year for the services we'd use, $297 to $447 across three years.
The state's fees stay the same whoever you name.
What does an agent actually do?
Court papers and state notices for your company get delivered to its Arizona address.
What matters is that nothing important sits there unnoticed while you're away. What's service of process?
What else does the state bill every year?
Nothing recurs on the report side, because Arizona doesn't ask for one.
What put number one on top?
On money out the door in three years (35% of the score), AZ Registered Agent.org wins.
We run five tests: money out the door in three years (35%), jobs the price actually covers (30%), no hunting for the price (14%), no surprise at renewal (11%) and where it works (10%).
Mainstay Filing costs $150 more over three years than AZ Registered Agent.org, which comes to $297.

The rows above, added up
The last row is our math, not the state's: filing fee, plus the reports in years two and three, plus any minimum tax. If a cost has no fixed amount, like a newspaper notice, it's explained above and left out.
More questions
Can I be my own agent?
Yes, if your address and status match the rule. Lots of owners still pay a service to keep their address private.
Which addresses count?
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?
Over three years you're looking at $297 at AZ Registered Agent.org, $447 at Mainstay Filing, $297 at Arizona Registered Agent.co
Are the fees official?
Each state fee links to its official page, and each service price comes from the company's own site.
Do I have to use a service?
No law says you need a service. It's a convenience you pay for.
What's the best registered agent in Arizona?
AZ Registered Agent.org is first: a company that never leaves Arizona pays $297 over three years. Then comes Mainstay Filing and Arizona Registered Agent.co.
