3 Best LLC Services in Arizona (2026)
1. Mainstay Filing: best for one all-in yearly line
$199 a year plus the state fee
Mainstay Filing is rated first: $199 covers the Arizona formation and a year as statutory agent, EIN application included.
With no yearly LLC report in Arizona, the renewal line after year one is the statutory agent alone (the first-year bundle also carried the EIN application).
On three-year sums Mainstay is $200 above Arizona Registered Agent.co; the wider coverage justifies that gap in the rating.

Pros
- One $199 yearly line
- Arizona's fee goes through at cost
- EIN application is in the package

Why the order looks like this
The rating method counts cost over years one to three and inclusions per price at 27% each and splits 46% among renewal price and terms, fit with state rules and price clarity. For Arizona, inclusions per price was the deciding line.
Arizona has no yearly report to file, so the bundle is worth less, yet one fixed amount with the EIN application included still rated above Arizona Registered Agent.co on coverage.
Each criterion and its weight is listed on How we rank.
Arizona LLC formation: official amount and form
Filing the Articles of Organization (Form L010) costs $50, paid to the Arizona Corporation Commission. Each service here passes that amount through at cost, added to its own.
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.
Ongoing items for a Arizona LLC
