Opened up, question by question

Is a statutory agent required?

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

The law underneath: A.R.S. § 29-3115. peek at azleg.gov, confirmed October 2026

Who qualifies?

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.

If you qualify, you can serve yourself at no cost.

What is inside an agent's price?

$99 to $149 annually, $297 to $447 in total across three years.

Changing agents never changes a state fee.

Why does the state want an agent?

Whatever legal paper is meant for the LLC in Arizona goes to the agent, who passes it along.

Ask how quickly the agent tells you when something arrives, so no deadline slips by. What is service of process?

What does the LLC owe the state each year?

Arizona has no yearly report, so the report layer is empty.

Why is the stack in this order?

Arizona Registered Agent.co wins the total across three years layer, which counts 34%.

Two layers carry most of the weight, total across three years (34%) and what is inside the price (29%).

Arizona Registered Agent.co stacks up to $297 over three years, $150 under Mainstay Filing.

More boxes to open

May an owner serve as agent?

Yes, when your address and status match the rule. Many owners still hire a service to keep an address private.

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.

How do the three-year totals compare?

Arizona Registered Agent.co runs to $297 and Mainstay Filing runs to $447 and AZ Registered Agent.org runs to $297

What do these numbers rest on?

Official Arizona paperwork stands behind every state fee here, and every service price traces back to the company's own pricing.

Does the law require one?

No law requires a service. It is a paid convenience.

Who tops the stack in Arizona?

Arizona Registered Agent.co, because three years for a Arizona-only company come to $297. Then Mainstay Filing and AZ Registered Agent.org.
