How Delaware companies register with Wisconsin
Order the Delaware certificate
The Certificate of Good Standing ($50) is ordered from Delaware separately; it is not part of our Wisconsin order. It comes as a short form ($50) or a long form ($175). Delaware mails it, and Wisconsin counts the 60 days from issue, so it is ordered with transit in mind.
We prepare and file Form 21
It names us as your Wisconsin registered agent, with your Delaware name and formation date and the certificate attached. Allow for the days Delaware takes to send the certificate before the Wisconsin filing goes in. Once Wisconsin approves it, the Delaware company can do business there.

Your Delaware name and Wisconsin's rules
We search Wisconsin's records for Delaware's name on file before anything is filed.
Your Wisconsin agent and the Delaware one
Delaware and Wisconsin both call it a registered agent. Your current registered agent stays for Delaware; ours takes Wisconsin's papers and notices.
Yearly filings: Wisconsin and Delaware
Each year your corporation files Delaware's Annual Franchise Tax Report ($50) and Wisconsin's Foreign Business Corporation Annual Report ($65). With our $149 registered agent renewal, Delaware plus Wisconsin comes to $264 a year. Both states' filings stay current side by side.
LLC or corporation, Delaware to Wisconsin
An LLC formed in Delaware files Form 521 with Wisconsin ($100 in state fees, the same; no home-state certificate is needed). After that come Delaware's Annual LLC Tax ($400) and Wisconsin's Annual Report (Form 5 / CORP5) ($80). See the LLC filing.
The other way: Wisconsin into Delaware
A corporation formed in Wisconsin that registers with Delaware files Delaware's registration (no form number) with $245 in state fees. See that filing.
Questions Delaware owners ask about Wisconsin
Does my Delaware company need to register in Wisconsin?
Yes, once a Delaware business operates there; Wisconsin does not count a one-off deal finished within 30 days.
Is this a certificate of authority?
Yes: Wisconsin issues one to Delaware corporations once the form is approved.
How much does it cost to register a Delaware corporation in Wisconsin?
$299 at checkout plus $50 to Delaware for the Certificate of Good Standing, $349 in all (checkout is $100 in state fees plus our $199).
Do I need Delaware's certificate of good standing?
Yes: Wisconsin wants it ($50), no more than 60 days old at filing.
What are the yearly costs for Delaware and Wisconsin?
$264 a year: our $149 registered agent renewal, $50 to Delaware and $65 to Wisconsin for the yearly reports.
What if I don't register with Wisconsin?
Wisconsin can charge a Delaware company up to $65 for each year or part of a year.
Does Wisconsin require a registered agent?
Yes: the Delaware registered agent stays, and ours covers Wisconsin for year one.
Can I form a new Wisconsin corporation instead?
Yes, but Delaware keeps the original, so you run two companies: the new one files Wisconsin's Domestic Business Corporation Annual Report ($25), and the original keeps Delaware's Annual Franchise Tax Report.
