Mississippi LLC Foreign Registration in Wisconsin
To do business in Wisconsin, an LLC formed in Mississippi registers there on Form 521, with $100 in state fees. Wisconsin asks nothing of Mississippi here, not even the Certificate of Good Standing / Certificate of Existence. We file it with the Department of Financial Institutions, Division of Corporate and Consumer Services from your Mississippi records, then serve as your registered agent there for year one.

From Mississippi to Wisconsin, step by step
We prepare and file Form 521
It names us as your Wisconsin registered agent, with your Mississippi name and formation date. No Mississippi paperwork holds up the Wisconsin filing. After approval, your Mississippi LLC is registered with Wisconsin.
Your Mississippi name and Wisconsin's rules
We check your exact Mississippi name against Wisconsin's records before filing.
Agents: Wisconsin and Mississippi
Mississippi and Wisconsin both call it a registered agent. Your current registered agent stays for Mississippi; ours takes Wisconsin's papers and notices.
Yearly filings: Wisconsin and Mississippi
Each year your LLC files Mississippi's Annual Report (no fee) and Wisconsin's Annual Report (Form 5 / CORP5) ($80). With our $149 registered agent renewal, Mississippi plus Wisconsin comes to $229 a year. Both states' filings stay current side by side.
LLC or corporation, Mississippi to Wisconsin
A corporation formed in Mississippi files Form 21 with Wisconsin ($100 in state fees, the same, plus the Certificate of Good Standing / Certificate of Existence ($25)). After that come Mississippi's Annual Report ($25) and Wisconsin's Foreign Business Corporation Annual Report ($65). See the corporation filing.
The other way: Wisconsin into Mississippi
An LLC formed in Wisconsin that registers with Mississippi files Form F0200 with $250 in state fees, plus the Certificate of Status ($10) dated within 180 days. See that filing.
Questions Mississippi owners ask about Wisconsin
Does my Mississippi company need to register in Wisconsin?
Yes, once a Mississippi business operates there; Wisconsin law lists 11 activities that do not count on their own.
How much does it cost to register a Mississippi LLC in Wisconsin?
$299 at checkout, with nothing to pay Mississippi.
Do I need Mississippi's certificate of good standing?
No, Wisconsin takes Form 521 without it.
What are the yearly costs for Mississippi and Wisconsin?
$229 a year: our $149 registered agent renewal, nothing to Mississippi and $80 to Wisconsin for the yearly reports.
What if I don't register with Wisconsin?
A Mississippi 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 Mississippi registered agent stays, and ours covers Wisconsin for year one.
Can I form a new Wisconsin LLC instead?
Yes, but Mississippi keeps the original, so you run two companies: the new one files Wisconsin's Annual Report (Form 5 / CORP5) ($25), and the original keeps Mississippi's Annual Report.
How do I withdraw from Wisconsin later?
Mississippi companies leave by filing a Withdrawal of Registration of Foreign Limited Liability Company; until then, Wisconsin's report stays due alongside Mississippi's filings.
