Questions owners ask
How much money do I need to start?
The state charges $50, and a service that files for you in year one adds $199.
State fees for years one through three come to $50. azcc.gov, read in October 2026 for this answer
Publication: a notice runs three times within 60 days unless the statutory agent is in a county of more than 800,000 people, where the Commission posts it instead.

The Arizona Corporation Commission receives the Articles of Organization (Form L010), and once it approves, the LLC exists.
The law behind it: Ariz. Rev. Stat. § 29-3201. azcc.gov, read in October 2026 for this answer
Does this state require a statutory agent?
Every LLC must name a registered agent with an in-state street address.
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.
Arizona wants no report, which leaves nothing to file.
Do I have to pay someone to do this?
A service is optional. State fees alone are $50 across three years.
Paying for help raises the three-year total by $397 to $597, which buys the paperwork and the agent role.
Why is the list in this order?
Arizona Registered Agent.co does best on what you pay over three years, which carries 33% of our score.
We weigh five questions: what you pay over three years (33%), chores the price takes care of (29%), answers on the price page (14%), what happens at renewal (13%) and room to add states (11%).
Arizona Registered Agent.co totals $397 across three years, which is $200 under Mainstay Filing.
How was the bottom line figured? Add the filing fee, the next two reports and the minimum tax if the state has one. Anything with no fixed price, a newspaper notice for instance, is described above and kept out of the sum.

No. What the law asks for is a filing, and it does not say who has to send it.
