From Missouri to Maine, step by step
We prepare and file Form MBCA-12
It lists us as your Maine registered agent, next to your Missouri name and formation date. If Maine wants the Missouri certificate, it is ordered first. Once Maine approves it, the Missouri company can do business there.
Will your Missouri name work for Maine?
We check your exact Missouri name against Maine's records before filing.
Your Maine agent and the Missouri one
Missouri and Maine both call it a registered agent. Maine papers come to us; Missouri's agent is unchanged.
Yearly filings: Maine and Missouri
Missouri wants the Corporate Registration Report every two years ($15); Maine wants the Annual Report every year ($150). The new registration does not replace any home-state filing.
LLC or corporation, Missouri to Maine
An LLC formed in Missouri files Form MLLC-12 with Maine ($250 in state fees and the $50 required expedite, the same, plus the Certificate of Good Standing ($10)). See the LLC filing.
The other way: Maine into Missouri
A corporation formed in Maine that registers with Missouri files Form Corp 42 with $155 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 13 activities that do not count on their own.
Is this a certificate of authority?
Yes: Maine issues one to Missouri corporations once the form is approved.
How much does the Maine registration cost?
$499 at checkout, including the $50 required expedite; Maine may also want Missouri's Certificate of Good Standing, at extra cost.
How long does the Maine registration take?
24 hours with Maine's required expedite, plus time for Missouri's certificate if Maine asks for it. Faster state options: same-day $100.
What are the yearly costs for Missouri and Maine?
Our registered agent renewal ($149 a year), Missouri's report ($15, every two years) 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 corporation instead?
Yes, but Missouri keeps the original, so you run two companies: the new one files Maine's Annual Report ($85), and the original keeps Missouri's Corporate Registration Report.
How do I withdraw from Maine later?
Missouri companies leave by filing an Application of Withdrawal; until then, Maine's report stays due alongside Missouri's filings.
