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

From Maryland to Wisconsin, step by step
We prepare and file Form 521
It lists us as your Wisconsin registered agent, next to your Maryland name and formation date. No Maryland paperwork holds up the Wisconsin filing. Once Wisconsin approves it, the Maryland company can do business there.
Will your Maryland name work for Wisconsin?
We check your exact Maryland name against Wisconsin's records before filing.
Agents: Wisconsin and Maryland
Wisconsin calls it a registered agent; Maryland says resident agent. Wisconsin papers come to us; Maryland's agent is unchanged.
Staying in good standing in Maryland and Wisconsin
Each year your LLC files Maryland's Business Entity Annual Report (Form 1) ($300) and Wisconsin's Annual Report (Form 5 / CORP5) ($80). With our $149 registered agent renewal, Maryland plus Wisconsin comes to $529 a year. The new registration does not replace any home-state filing.
LLC or corporation, Maryland to Wisconsin
A corporation formed in Maryland files Form 21 with Wisconsin ($100 in state fees, the same, plus the Certificate of Status ($20)). After that come Maryland's periodic report ($300) and Wisconsin's Foreign Business Corporation Annual Report ($65). See the corporation filing.
Registering a Wisconsin company in Maryland
An LLC formed in Wisconsin that registers with Maryland files Maryland's registration (no form number) with $104.50 in state fees and a $50 required expedite, plus the Certificate of Status ($10) dated within 60 days. See that filing.
Questions Maryland owners ask about Wisconsin
Does my Maryland company need to register in Wisconsin?
Yes, once a Maryland business operates there; Wisconsin law lists 11 activities that do not count on their own.
How much does it cost to register a Maryland LLC in Wisconsin?
$299 at checkout, with nothing to pay Maryland.
Do I need Maryland's certificate of good standing?
No, Wisconsin takes Form 521 without it.
What are the yearly costs for Maryland and Wisconsin?
$529 a year: our $149 registered agent renewal, $300 to Maryland and $80 to Wisconsin for the yearly reports.
What if I don't register with Wisconsin?
A Maryland 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 Maryland resident agent stays, and ours covers Wisconsin for year one.
Can I form a new Wisconsin LLC instead?
Yes, but Maryland keeps the original, so you run two companies: the new one files Wisconsin's Annual Report (Form 5 / CORP5) ($25), and the original keeps Maryland's Business Entity Annual Report (Form 1).
How do I withdraw from Wisconsin later?
Maryland companies leave by filing a Withdrawal of Registration of Foreign Limited Liability Company; until then, Wisconsin's report stays due alongside Maryland's filings.
