Mainstay's agent plan brings more to the table: served papers are scanned the same business day for nothing, one price in all fifty states and three government mailings a year scanned free. AZ Registered Agent.org is cheaper, and it was close.

Arizona statutory agent rules straight from Arizona Corporation Commission (official)

Every LLC must name a registered agent with an in-state street address. 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. The law behind it: A.R.S. § 29-3115.

Does Arizona want a yearly report?

Arizona has no yearly LLC report. What it does require all year is a statutory agent on record, and notices go to that address.

Arizona registered agent: reader questions

Do you need a statutory agent to run an Arizona LLC?

You do. Arizona wants a statutory agent on file for every LLC, and the agent must have a street address in the state.

What should you expect to pay a Arizona registered agent?

Plan on $99 to $149 a year, and the price holds when it renews.

Could you serve as your own statutory agent?

You can if the state's rules allow it. 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.

Which registered agents did the desk rank here?

Mainstay Filing ($149 a year), AZ Registered Agent.org ($99 a year) and Arizona Registered Agent.co ($99 a year), best pick first.

What does a statutory agent do all day?

The statutory agent is the company's official mailbox for lawsuits, subpoenas and state notices. It accepts them and passes them along, and every plan on this page scans them to your online account.

Who is our pick for registered agent in Arizona?

Mainstay Filing, since $149 a year, and it holds on renewal, with papers served on the company scanned the same business day for free.
