What you need to know

When does an out-of-state LLC have to register?

Before your LLC does business in Arizona. You register with the Arizona Corporation Commission, Corporations Division, then you start working.

If you skip it, expect it can't sue in Arizona courts until it registers (A.R.S. 29-3902(B)).

What's it cost to register?

The state charges $150, and a service adds $199.

Over three years the state's fees reach $150, counting any recurring report. go check azcc.gov, last confirmed October 2026

What registers the LLC?

The form's the Foreign Registration Statement (Form L025), and the Arizona Corporation Commission, Corporations Division gets it.

Attach certificate of existence or good standing, plus a certified copy of the organizational documents no older than 60 days.

What do I owe once I'm registered?

Nothing has to be filed on a schedule.

What put number one on top?

On jobs the price actually covers (30% of the score), Mainstay Filing wins.

We run five tests: money out the door in three years (35%), jobs the price actually covers (30%), no hunting for the price (14%), no surprise at renewal (11%) and where it works (10%).

More questions

Do I still need an agent at home?

Each state sets its own rule, so keep an agent at home too. A provider that works in every state, like Mainstay Filing, can handle both.

What's the three-year damage for each?

Over three years you're looking at $497 at Mainstay Filing, $397 at AZ Registered Agent.org, $397 at Arizona Registered Agent.co, before state fees.

Where do these numbers come from?

Each state fee links to its official page, and each service price comes from the company's own site.

Is a service required?

No. You can file with the state yourself. A service saves you time and can be your agent, but nothing makes you hire one.

Will a service file it for me?

All of them do, so the service fee's the only difference.

Who should I use for a foreign registration service in Arizona?

Mainstay Filing is first: you pay $199 on top of the state fee, the statutory agent costs nothing in year one, and after that it's $149. Then comes AZ Registered Agent.org and Arizona Registered Agent.co.
