From Pennsylvania to Wisconsin, step by step
We prepare and file Form 521
It names us as your Wisconsin registered agent, with your Pennsylvania name and formation date. Nothing has to come from Pennsylvania first, so the Wisconsin filing can go in right away. After approval, your Pennsylvania LLC is registered with Wisconsin.
Will your Pennsylvania name work for Wisconsin?
We check your exact Pennsylvania name against Wisconsin's records before filing.
Your Wisconsin agent and the Pennsylvania one
Wisconsin calls it a registered agent; Pennsylvania says registered office. Your current registered office stays for Pennsylvania; ours takes Wisconsin's papers and notices.
Staying in good standing in Pennsylvania and Wisconsin
Each year your LLC files Pennsylvania's Annual Report ($7) and Wisconsin's Annual Report (Form 5 / CORP5) ($80). With our $149 registered agent renewal, Pennsylvania plus Wisconsin comes to $236 a year. Both states' filings stay current side by side.
LLC or corporation, Pennsylvania to Wisconsin
A corporation formed in Pennsylvania files Form 21 with Wisconsin ($100 in state fees, the same, plus the Subsistence Certificate ($40)). After that come Pennsylvania's Annual Report ($7) and Wisconsin's Foreign Business Corporation Annual Report ($65). See the corporation filing.
Registering a Wisconsin company in Pennsylvania
An LLC formed in Wisconsin that registers with Pennsylvania files Form DSCB:15-412 with $250 in state fees; no Wisconsin certificate is needed. See that filing.
Common questions: Pennsylvania to Wisconsin
Does my Pennsylvania company need to register in Wisconsin?
Yes, once a Pennsylvania 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 Pennsylvania.
Do I need Pennsylvania's certificate of good standing?
No, Wisconsin takes Form 521 without it.
What are the yearly costs for Pennsylvania and Wisconsin?
$236 a year: our $149 registered agent renewal, $7 to Pennsylvania and $80 to Wisconsin for the yearly reports.
What if I don't register with Wisconsin?
A Pennsylvania 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 Pennsylvania registered office stays, and ours covers Wisconsin for year one.
Can I form a new Wisconsin LLC instead?
Yes, but Pennsylvania keeps the original, so you run two companies: the new one files Wisconsin's Annual Report (Form 5 / CORP5) ($25), and the original keeps Pennsylvania's Annual Report.
How do I withdraw from Wisconsin later?
Pennsylvania companies leave by filing a Withdrawal of Registration of Foreign Limited Liability Company; until then, Wisconsin's report stays due alongside Pennsylvania's filings.
