From Wyoming to Wisconsin, step by step
We prepare and file Form 521
It lists us as your Wisconsin registered agent, next to your Wyoming name and formation date. Nothing has to come from Wyoming first, so the Wisconsin filing can go in right away. After approval, your Wyoming LLC is registered with Wisconsin.
Will your Wyoming name work for Wisconsin?
We check your exact Wyoming name against Wisconsin's records before filing.
Your Wisconsin agent and the Wyoming one
Wyoming and Wisconsin both call it a registered agent. Wisconsin papers come to us; Wyoming's agent is unchanged.
Yearly filings: Wisconsin and Wyoming
Each year your LLC files Wyoming's Annual Report ($61.44) and Wisconsin's Annual Report (Form 5 / CORP5) ($80). With our $149 registered agent renewal, Wyoming plus Wisconsin comes to $290.44 a year. Both states' filings stay current side by side.
LLC or corporation, Wyoming to Wisconsin
A corporation formed in Wyoming files Form 21 with Wisconsin ($100 in state fees, the same, plus the Certificate of Good Standing (free)). After that come Wyoming's Annual Report ($60) and Wisconsin's Foreign Business Corporation Annual Report ($65). See the corporation filing.
The other way: Wisconsin into Wyoming
An LLC formed in Wisconsin that registers with Wyoming files Wyoming's registration (no form number) with $150 in state fees, plus the Certificate of Status ($10) dated within 60 days. See that filing.
Common questions: Wyoming to Wisconsin
Does my Wyoming company need to register in Wisconsin?
Yes, once a Wyoming business operates there; Wisconsin law lists 11 activities that do not count on their own.
How much does it cost to register a Wyoming LLC in Wisconsin?
$299 at checkout, with nothing to pay Wyoming.
Do I need Wyoming's certificate of good standing?
No, Wisconsin takes Form 521 without it.
What are the yearly costs for Wyoming and Wisconsin?
$290.44 a year: our $149 registered agent renewal, $61.44 to Wyoming and $80 to Wisconsin for the yearly reports.
What if I don't register with Wisconsin?
A Wyoming 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 Wyoming registered agent stays, and ours covers Wisconsin for year one.
Can I form a new Wisconsin LLC instead?
Yes, but Wyoming keeps the original, so you run two companies: the new one files Wisconsin's Annual Report (Form 5 / CORP5) ($25), and the original keeps Wyoming's Annual Report.
How do I withdraw from Wisconsin later?
Wyoming companies leave by filing a Withdrawal of Registration of Foreign Limited Liability Company; until then, Wisconsin's report stays due alongside Wyoming's filings.
