Why Mainstay Filing is placed first
Two criteria carry 31% each in this ranking, charge over three years and work taken off the founder. Renewal conduct, fit with local rules and pricing in plain sight share 38%, and in Arizona the decisive one was work taken off the founder.
Mainstay's plan reaches further: papers served on the company are scanned within the same business day at no cost, the price is identical across all fifty states, and three government letters a year are scanned free. AZ Registered Agent.org charges less, so the margin is narrow.
Each criterion and its weight appear on How we rank.
What Arizona requires of a statutory agent (source: Arizona Corporation Commission)
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. Authority: A.R.S. § 29-3115.
Recurring duties once an agent is appointed in Arizona
Arizona sets no yearly LLC report. The standing duty is to keep a statutory agent on record, because the state directs its notices there.
Questions on Arizona registered agents
Is an Arizona LLC obliged to appoint a statutory agent?
Yes. Arizona law expects every LLC to appoint a statutory agent with a physical address in the state, and that appointment is public.
What is the going yearly rate for a Arizona registered agent?
Yearly charges fall between $99 to $149, and every provider holds its price at renewal.
Is the owner permitted to serve as the statutory agent?
Yes, when the state's conditions are met. 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 were heard in this ranking?
Mainstay Filing ($149 a year), AZ Registered Agent.org ($99 a year) and Arizona Registered Agent.co ($99 a year), ruled upon in that order.
What is expected of a statutory agent?
The statutory agent is the company's address of record for lawsuits, subpoenas and state notices. It accepts them and passes them on, and each plan here delivers them to your online account as scans.
Which Arizona registered agent does the record favor?
Mainstay Filing, since its agent plan is $149 a year and does not rise at renewal, and legal papers served on the company are scanned within the same business day free of charge.
