Maine Corporation Foreign Registration in Missouri
To do business in Missouri, a corporation formed in Maine registers there on Form Corp 42, with $155 in state fees. Missouri also wants Maine's Certificate of Existence ($30), dated within 60 days.

From Maine to Missouri, step by step
Order the Maine certificate
The Certificate of Existence ($30) is ordered from Maine separately; it is not part of our Missouri order. Missouri accepts it within 60 days of Maine'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 Maine name and formation date and the certificate attached. The Maine certificate comes first; then the Missouri filing goes in. After approval, your Maine corporation is registered with Missouri.

Your Missouri agent and the Maine one
Maine and Missouri both call it a registered agent. Missouri papers come to us; Maine's agent is unchanged.

Maine wants the Annual Report every year ($85); Missouri wants the Corporate Registration Report every two years ($15). The new registration does not replace any home-state filing.

An LLC formed in Maine files Form LLC 4 with Missouri ($105 in state fees, plus the Certificate of Existence ($30)). See the LLC filing.
The other way: Missouri into Maine
A corporation formed in Missouri that registers with Maine files Form MBCA-12 with $250 in state fees and a $50 required expedite. See that filing.
Common questions: Maine to Missouri
Does my Maine company need to register in Missouri?
Yes, once a Maine business operates there; Missouri law lists 8 activities that do not count on their own.
Is this a certificate of authority?
Yes: Missouri issues one to Maine corporations once the form is approved.
How much does the Missouri registration cost?
$354 at checkout plus $30 to Maine for the Certificate of Existence, $384 in all (checkout is $155 in state fees plus our $199).
Do I need Maine's certificate of good standing?
Yes: Missouri wants Maine's Certificate of Existence ($30), no more than 60 days old at filing.
What are the yearly costs for Maine and Missouri?
Our registered agent renewal ($149 a year), Maine's report ($85) and Missouri's report ($15, every two years).
What if I don't register with Missouri?
A Maine 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 Maine registered agent stays, and ours covers Missouri for year one.
Can I form a new Missouri corporation instead?
Yes, but Maine keeps the original, so you run two companies: the new one files Missouri's Corporate Registration Report ($15), and the original keeps Maine's Annual Report.
How do I withdraw from Missouri later?
Maine companies leave by filing an Application for Certificate of Withdrawal; until then, Missouri's report stays due alongside Maine's filings.
