Your questions, answered

Will the state make me name a statutory agent?

Every LLC must name a registered agent with an in-state street address.

The law behind it: A.R.S. § 29-3115. azleg.gov, confirmed October 2026 (official)

What does the state require of an agent?

An Arizona resident, or a corporation or LLC formed in Arizona or authorized to do business there. The appointment takes effect only once the agent accepts it in writing.

An owner who meets the rule may be the agent with no charge from the state.

What should I budget for an agent?

Budget $99 to $149 a year, or $297 to $447 for three.

Whoever you name, state fees stay the same.

What does an agent do for the LLC?

It collects lawsuits and official state mail for your LLC at an address in Arizona.

What matters is that nothing important goes unnoticed while you're out. What does "service of process" mean?

What does the state want from the LLC annually?

Nothing comes back around on the report side, since Arizona doesn't ask for one.

Why is the list in this order?

Mainstay Filing is strongest on work taken off your hands, which counts for 31% of our score.

33% of the score is cost across three years, 31% is work taken off your hands, and three smaller checks split ties.

Where a service can be used counts with us, and one pick can be used anywhere.
