Best overall

1. Mainstay Filing: best for LLCs on the move

$199 plus the state fee, then $149 a year

In Arizona, Mainstay Filing sits at the top of the class: a $199 service fee plus Arizona's own fee, then $149 a year for the agent.

Next to Arizona Registered Agent.co the three-year premium is $100, which the 34% weight on homework done outweighs.

The agent renews at $149 a year in every state.

The class, assignment by assignment

  1. Assignment
    1

    Is Arizona registration needed?

    Vocabulary word: a foreign LLC is one formed in a different state. It registers before it does business in Arizona. Skipping registration has a price: Until it registers, the LLC cannot sue in Arizona's courts (A.R.S. 29-3902(B)). The agreements are not voided (A.R.S. 29-3902(C)).

  2. Assignment
    2

    Collect the document from the home state

    Your filing must include certificate of existence or good standing, plus a certified copy of the organizational documents, not older than 60 days.

    A recent certificate is the best kind, so order it late.

  3. Assignment
    3

    Arrange an Arizona statutory agent

    Every LLC must name a registered agent with an in-state street address. The address has to be a place of business or residence in Arizona with a street address. A P.O. box can be listed only as a separate Arizona mailing address.

    The services above supply one.

    Put together and mail the Foreign Registration Statement

    The form and the $150 fee go to the Arizona Corporation Commission, Corporations Division together.

    Stay registered

    Arizona asks nothing recurring of a foreign LLC.

The bill

What forWho gets paidAmount
Registering the LLCThe state$150
Optional serviceThe service$199 in the first year
Three-year state totalThe state$150
Anything paid to Arizona is an official fee you can look up on the pages listed below. The three-year row combines the filing, two later reports and a minimum tax where there is one, and service prices are not part of it.

Why Mainstay Filing is first

On homework the price does (34% of the grade) came out on top, with close behind.

Your LLC was formed in one state and works in another, so a provider that serves both earned the best grade.

What students ask

What does an LLC from elsewhere pay to register in Arizona?

$150 to the state. Service fees: $199.

Which form do I file to register?

Fill in the form named in assignment 4 and send it to the Arizona Corporation Commission, Corporations Division.

Do I need a certificate from my home state?

Yes: certificate of existence or good standing, plus a certified copy of the organizational documents, issued within 60 days of filing.

What if the LLC does business there without registering?

Until it registers, the LLC cannot sue in Arizona's courts (A.R.S. 29-3902(B)). The agreements are not voided (A.R.S. 29-3902(C)).

What is due after registering?

No recurring report for foreign LLCs in Arizona.

Which service should handle the registration?

The grade order is Mainstay Filing, Arizona Registered Agent.co and AZ Registered Agent.org, and Mainstay Filing is first since registering costs $199 plus state fees, and year one of the statutory agent costs nothing.
