Each charge was taken from the provider's own pages on November 12, 2026. Arizona's $150 registration fee is payable in addition to every row below and is not in the totals.
Why Mainstay Filing is placed first
The Startup Judge weighs charge over three years at 31% and work taken off the founder at 31%; renewal conduct, fit with local rules and pricing in plain sight divide the remaining 38%. In Arizona, work taken off the founder was the criterion that tipped it.
A second-state registration involves two jurisdictions. One provider at one price in both earned the higher coverage score, ahead of AZ Registered Agent.org.
