The working behind Arizona
For Arizona, the deciding term was filing work in the price (27% of the formula), where Mainstay Filing came out ahead.
The bundle has less to add in this state, though it still led on work covered per dollar.
Count the EIN application and AZ Registered Agent.org calculates lower from year 2.
How Arizona describes its LLC filing fee and filing requirements
You submit the Articles of Organization (Form L010) to the Arizona Corporation Commission along with $50 (Ariz. Rev. Stat. § 29-3201). Every LLC must name a registered agent with an in-state street address.
- 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 no-service result
File alone and Arizona still bills $50 over three years, with every form on your desk. A service charging $397 to $597 removes that work.
