How Connecticut companies register with Missouri
Order the Connecticut certificate
The Certificate of Legal Existence ($80) is ordered from Connecticut separately; it is not part of our Missouri order. It comes as a short form ($80) or a long form ($120). Missouri accepts it within 60 days of Connecticut's issue date, so it is ordered shortly before filing.
We prepare and file Form Corp 42
It names us as your Missouri registered agent, with your Connecticut name and formation date and the certificate attached. The Connecticut certificate comes first; then the Missouri filing goes in. Once Missouri approves it, the Connecticut company can do business there.

Common questions: Connecticut to Missouri
Does my Connecticut company need to register in Missouri?

Is this a certificate of authority?
Yes: Missouri issues one to Connecticut corporations once the form is approved.
How much does the Missouri registration cost?
$354 at checkout plus $80 to Connecticut for the Certificate of Legal Existence, $434 in all (checkout is $155 in state fees plus our $199).
Do I need Connecticut's certificate of good standing?
Yes: Missouri wants Connecticut's Certificate of Legal Existence ($80), no more than 60 days old at filing.
What are the yearly costs for Connecticut and Missouri?
Our registered agent renewal ($149 a year), Connecticut's report ($150) and Missouri's report ($15, every two years).
What if I don't register with Missouri?
A Connecticut company cannot sue in court there until it registers, and Missouri can add a fine of at least $1,000.
Does Missouri require a registered agent?
Yes: the Connecticut registered agent stays, and ours covers Missouri for year one.
Can I form a new Missouri corporation instead?
Yes, but Connecticut keeps the original, so you run two companies: the new one files Missouri's Corporate Registration Report ($15), and the original keeps Connecticut's Annual Report.
How do I withdraw from Missouri later?
Connecticut companies leave by filing an Application for Certificate of Withdrawal; until then, Missouri's report stays due alongside Connecticut's filings.
