Our top pick

1. Mainstay Filing: best for a single all-in yearly price

$199 a year plus the state fee

Editorial score 9.1 out of 10

The desk picks Mainstay Filing: $199 pays for the Arizona formation and a year of statutory agent service, EIN application included.

Arizona has no yearly LLC report, so after year one you are paying the renewal for the statutory agent alone (the EIN application was part of the first-year bundle).

Over three years Mainstay runs $200 more than Arizona Registered Agent.co, and the desk thinks the wider coverage is worth it.
