How Missouri companies register with Maine
Order the Missouri certificate
The Certificate of Good Standing ($10) is ordered from Missouri separately; it is not part of our Maine order. Maine accepts it within 90 days of Missouri's issue date, so it is ordered shortly before filing.
We prepare and file Form MLLC-12
It lists us as your Maine registered agent, next to your Missouri name and formation date, with the certificate attached. Once Missouri's certificate is in hand, Maine's filing goes in. After approval, your Missouri LLC is registered with Maine.

Your Missouri name and Maine's rules
We search Maine's records for Missouri's name on file before anything is filed.
Your Maine agent and the Missouri one
Missouri and Maine both call it a registered agent. Your current registered agent stays for Missouri; ours takes Maine's papers and notices.
Staying in good standing in Missouri and Maine
Missouri has no annual report for LLCs; Maine wants the Annual Report every year ($150). The new registration does not replace any home-state filing.
LLC or corporation, Missouri to Maine
A corporation formed in Missouri files Form MBCA-12 with Maine ($250 in state fees and the $50 required expedite, the same). After that come Missouri's Corporate Registration Report ($15) and Maine's Annual Report ($150). See the corporation filing.
Registering a Maine company in Missouri
An LLC formed in Maine that registers with Missouri files Form LLC 4 with $105 in state fees, plus the Certificate of Existence ($30) dated within 60 days. See that filing.
Questions Missouri owners ask about Maine
Does my Missouri company need to register in Maine?
Yes, once a Missouri business operates there; Maine law lists 11 activities that do not count on their own.
How much does the Maine registration cost?
$499 at checkout plus $10 to Missouri for the Certificate of Good Standing, $509 in all (checkout is $250 in state fees, the $50 required expedite and our $199).
Do I need Missouri's certificate of good standing?
Yes: Maine wants it ($10), no more than 90 days old at filing.
How long does the Maine registration take?
24 hours with Maine's required expedite, once Missouri's certificate is in hand. Faster state options: same-day $100.
What are the yearly costs for Missouri and Maine?
Our registered agent renewal ($149 a year), no Missouri yearly report and Maine's report ($150).
What if I don't register with Maine?
A Missouri company cannot sue in court there until it registers, and Maine can add up to $500 for each year or part of a year.
Does Maine require a registered agent?
Yes: the Missouri registered agent stays, and ours covers Maine for year one.
Can I form a new Maine LLC instead?
Yes, but Missouri keeps the original, so you run two companies: the new one files Maine's Annual Report ($85), and Missouri has no yearly report for the original.
How do I withdraw from Maine later?
Missouri companies leave by filing a Statement of Cancellation of Foreign Qualification; until then, Maine's report stays due alongside Missouri's filings.
