From Arizona to Wisconsin, step by step
We prepare and file Form 521
It names us as your Wisconsin registered agent, with your Arizona name and formation date. Nothing has to come from Arizona first, so the Wisconsin filing can go in right away. Once Wisconsin approves it, the Arizona company can do business there.
Your Arizona name and Wisconsin's rules
We check your exact Arizona name against Wisconsin's records before filing.
Agents: Wisconsin and Arizona
Wisconsin calls it a registered agent; Arizona says statutory agent. Wisconsin papers come to us; Arizona's agent is unchanged.
Staying in good standing in Arizona and Wisconsin
Arizona has no annual report for LLCs; Wisconsin wants the Annual Report (Form 5 / CORP5) every year ($80). Both states' filings stay current side by side.
LLC or corporation, Arizona to Wisconsin
A corporation formed in Arizona files Form 21 with Wisconsin ($100 in state fees, the same, plus the Certificate of Good Standing ($10)). After that come Arizona's Annual Report and Certificate of Disclosure ($45) and Wisconsin's Foreign Business Corporation Annual Report ($65). See the corporation filing.
Registering a Wisconsin company in Arizona
An LLC formed in Wisconsin that registers with Arizona files Form L025 with $153.30 in state fees and a $35 required expedite, plus the Certificate of Status ($10) dated within 60 days. See that filing.
Questions Arizona owners ask about Wisconsin
Does my Arizona company need to register in Wisconsin?
Yes, once an Arizona business operates there; Wisconsin law lists 11 activities that do not count on their own.
How much does it cost to register an Arizona LLC in Wisconsin?
$299 at checkout, with nothing to pay Arizona.
Do I need Arizona's certificate of good standing?
No, Wisconsin takes Form 521 without it.
What are the yearly costs for Arizona and Wisconsin?
Our registered agent renewal ($149 a year), no Arizona yearly report and Wisconsin's report ($80).
What if I don't register with Wisconsin?
An Arizona company cannot sue in court there until it registers, and Wisconsin can add up to $97.50 for each year or part of a year.
Does Wisconsin require a registered agent?
Yes: the Arizona statutory agent stays, and ours covers Wisconsin for year one.
Can I form a new Wisconsin LLC instead?
Yes, but Arizona keeps the original, so you run two companies: the new one files Wisconsin's Annual Report (Form 5 / CORP5) ($25), and Arizona has no yearly report for the original.
How do I withdraw from Wisconsin later?
Arizona companies leave by filing a Withdrawal of Registration of Foreign Limited Liability Company; until then, Wisconsin's report stays due alongside Arizona's filings.
