Louisiana LLC Foreign Registration in Wisconsin
An LLC formed in Louisiana that wants to do business in Wisconsin files Form 521, with $100 in state fees. Wisconsin needs nothing from Louisiana: no Certificate of Good Standing.

From Louisiana to Wisconsin, step by step
We prepare and file Form 521
It names us as your Wisconsin registered agent, with your Louisiana name and formation date. No Louisiana paperwork holds up the Wisconsin filing. After approval, your Louisiana LLC is registered with Wisconsin.
Your Louisiana name and Wisconsin's rules
We check your exact Louisiana name against Wisconsin's records before filing.
Agents: Wisconsin and Louisiana
Louisiana and Wisconsin both call it a registered agent. Wisconsin papers come to us; Louisiana's agent is unchanged.
Yearly filings: Wisconsin and Louisiana
Each year your LLC files Louisiana's Annual Report ($40) and Wisconsin's Annual Report (Form 5 / CORP5) ($80). With our $149 registered agent renewal, Louisiana plus Wisconsin comes to $269 a year. The new registration does not replace any home-state filing.
LLC or corporation, Louisiana to Wisconsin
A corporation formed in Louisiana files Form 21 with Wisconsin ($100 in state fees, the same, plus the Certificate of Good Standing ($25)). After that come Louisiana's Annual Report ($30) and Wisconsin's Foreign Business Corporation Annual Report ($65). See the corporation filing.
Registering a Wisconsin company in Louisiana
An LLC formed in Wisconsin that registers with Louisiana files Form 972 with $190 in state fees, plus the Certificate of Status ($10) dated within 90 days. See that filing.
Common questions: Louisiana to Wisconsin
Does my Louisiana company need to register in Wisconsin?
Yes, once a Louisiana business operates there; Wisconsin law lists 11 activities that do not count on their own.
How much does the Wisconsin registration cost?
$299 at checkout, with nothing to pay Louisiana.
Do I need Louisiana's certificate of good standing?
No, Wisconsin takes Form 521 without it.
What are the yearly costs for Louisiana and Wisconsin?
$269 a year: our $149 registered agent renewal, $40 to Louisiana and $80 to Wisconsin for the yearly reports.
What if I don't register with Wisconsin?
A Louisiana 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 Louisiana registered agent stays, and ours covers Wisconsin for year one.
Can I form a new Wisconsin LLC instead?
Yes, but Louisiana keeps the original, so you run two companies: the new one files Wisconsin's Annual Report (Form 5 / CORP5) ($25), and the original keeps Louisiana's Annual Report.
How do I withdraw from Wisconsin later?
Louisiana companies leave by filing a Withdrawal of Registration of Foreign Limited Liability Company; until then, Wisconsin's report stays due alongside Louisiana's filings.
