How Missouri companies register with Wisconsin
Order the Missouri certificate
The Certificate of Good Standing ($10) is ordered from Missouri separately; it is not part of our Wisconsin order. Wisconsin counts 60 days from the day Missouri issues it, so the order goes in shortly before filing.
We prepare and file Form 21
It lists us as your Wisconsin registered agent, next to your Missouri name and formation date, with the certificate attached. The Missouri certificate comes first; then the Wisconsin filing goes in. After approval, your Missouri corporation is registered with Wisconsin.

Common questions: Missouri to Wisconsin
Does my Missouri company need to register in Wisconsin?
Yes, once a Missouri 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 Missouri corporations once the form is approved.
How much does the Wisconsin registration cost?
$299 at checkout plus $10 to Missouri for the Certificate of Good Standing, $309 in all (checkout is $100 in state fees plus our $199).
Do I need Missouri's certificate of good standing?
Yes: Wisconsin wants it ($10), no more than 60 days old at filing.
What are the yearly costs for Missouri and Wisconsin?
Our registered agent renewal ($149 a year), Missouri's report ($15, every two years) and Wisconsin's report ($65).
What if I don't register with Wisconsin?
Wisconsin can charge a Missouri company up to $65 for each year or part of a year.
Does Wisconsin require a registered agent?
Yes: the Missouri registered agent stays, and ours covers Wisconsin for year one.
Can I form a new Wisconsin corporation instead?
Yes, but Missouri keeps the original, so you run two companies: the new one files Wisconsin's Domestic Business Corporation Annual Report ($25), and the original keeps Missouri's Corporate Registration Report.
