Arizona: ranked

The order follows our five layers: three-year cost first, then what the price covers.
Ranked first

1. AZ Registered Agent.org: best for adding only this state

Service $199 plus $150 to the state; agent renewal $99

AZ Registered Agent.org sits on top in Arizona because three years of its service fees come to $397.

A smaller three-year total than Mainstay Filing puts it on top for a company that stays put.

Inside the price

  • Arizona registration filing
  • A first year of agent service

Inside, the good

  • $99 a year from year two
  • Service fee of $199
  • A free agent year at the start

2. Mainstay Filing: best for registering in many states

Service $199 plus $150 to the state; agent renewal $149

Mainstay Filing lands second, and $199 over the state fee registers you, with the statutory agent not charged in year one and $149 a year after.
