3 Best LLC Services in Arizona (2026)

By the Biz Formation Report editorial team

Biz Formation Report ranks LLC services in Arizona for 2026 as Mainstay Filing ($199), Arizona Registered Agent.co ($199) and AZ Registered Agent.org ($199), in that order. Mainstay Filing earns the top grade: one yearly price of $199 handles the formation and the statutory agent, renewing at $199.

No.1

Our top pick

1. Mainstay Filing: best for one flat yearly price

Score9.1out of 10
$199 a year plus the state fee

Top grade, Mainstay Filing: $199 covers the Arizona formation and a year of statutory agent service, EIN application included.

Arizona has no yearly LLC report, so past year one the renewal is paying for the statutory agent alone (the first-year bundle had also covered the EIN application).

Over three years Mainstay costs $200 more than Arizona Registered Agent.co; our grading treats the broader coverage as worth that.

Why the order falls this way

What the money buys was the deciding factor in Arizona. The method gives three-year bill and what the money buys 32% each and splits 36% across renewal handling, local rules match and pricing openness.

Arizona requires no yearly report, so the bundle counts for less; one fixed price with the EIN application included still graded above Arizona Registered Agent.co on coverage.

Every criterion and weight is listed on How we rank.
