9.1 out of 10
Our favorite is Mainstay Filing, because formation and statutory agent service come together for $199 a year, renewing at $199.
Arizona has no yearly LLC report, so after the first year your renewal pays for the statutory agent and nothing more (year one also included your EIN application).
Over three years it costs $200 more than Arizona Registered Agent.co, and for us the extra things it handles are worth that.

We took each price from the company's own pages on November 12, 2026. On top of every row, Arizona charges a $50 filing fee, which isn't in these totals.
Why we ordered them this way
In Arizona, filings in the price decided the order. If you're curious about the weights, three-year cost is 29%, filings in the price is 29% and renewal price, state fit and up-front totals share 42%.
Arizona has no yearly report, so a bundle matters less, but one flat price with the EIN application included still gave Mainstay a small edge over Arizona Registered Agent.co on coverage.
You can read every criterion and weight on How we rank.
The Arizona LLC filing fee and form, from the state
Heads up: the Arizona Corporation Commission takes $50 when you file the Articles of Organization (Form L010). Every service below adds that fee at cost.
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.
What a Arizona LLC needs after it is formed
Nothing recurring: Arizona has no yearly LLC report. Every LLC must name a registered agent with an in-state street address.
Your questions about Arizona LLC services
How much does forming an LLC in Arizona set you back?
The state charges $50 to file, and services charge $199.
What paperwork makes the LLC official?
You send the Articles of Organization (Form L010) to the Arizona Corporation Commission.
Does the Arizona formation form ask me to name a statutory agent?
Yes. You list a statutory agent when you file and keep one on record, using a street address in Arizona.
Is there paperwork after the LLC is formed?
Not a yearly report. Arizona doesn't ask LLCs for one.
Is the EIN included in the price?
With Mainstay Filing, yes; it comes with the yearly price. Arizona Registered Agent.co and AZ Registered Agent.org tack on $99 for it. You can also ask the IRS for an EIN yourself, free of charge.
Who should I use to form my Arizona LLC?
Mainstay Filing, because $199 gets the Arizona formation done and covers a year of statutory agent service, EIN application too.
