From Maine to Idaho, step by step
We prepare and file the registration
It lists us as your Idaho registered agent, next to your Maine name and formation date. If Idaho wants the Maine certificate, it is ordered first. Once Idaho approves it, the Maine company can do business there.
Your Maine name and Idaho's rules
If Idaho's records show it taken, you can use an alternate name for the Maine company. We check your exact Maine name against Idaho's records before filing.
Your Idaho agent and the Maine one
Maine and Idaho both call it a registered agent. Idaho papers come to us; Maine's agent is unchanged.
Staying in good standing in Maine and Idaho
Each year your corporation files Maine's Annual Report ($85) and Idaho's Annual Report (no fee). With our $149 registered agent renewal, Maine plus Idaho comes to $234 a year. Both states' filings stay current side by side.
LLC or corporation, Maine to Idaho
An LLC formed in Maine files its own registration with Idaho ($103.50 in state fees, the same, plus the Certificate of Existence ($30)). After that come Maine's Annual Report ($85) and Idaho's Annual Report (no fee). See the LLC filing.
Registering an Idaho company in Maine
A corporation formed in Idaho 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 Idaho
Does my Maine company need to register in Idaho?
Yes, once a Maine business operates there; Idaho registers it as a foreign corporation.
Is this a certificate of authority?
Idaho calls it registration for Maine corporations; other states say certificate of authority.
How much does the Idaho registration cost?
$302.50 at checkout; Idaho may also want Maine's Certificate of Existence, at extra cost.
How long does the Idaho registration take?
Idaho's standard processing takes about 3 to 5 days from the date of filing, plus time for Maine's certificate if Idaho asks for it. Paid expedite: $40.
What are the yearly costs for Maine and Idaho?
$234 a year: our $149 registered agent renewal, $85 to Maine and nothing to Idaho for the yearly reports.
Does Idaho require a registered agent?
Yes: the Maine registered agent stays, and ours covers Idaho for year one, with a street address there.
Will Idaho accept my Maine name?
Yes, if no company there has it; if one does, it uses an alternate name there and keeps its Maine name at home.
Can I form a new Idaho corporation instead?
Yes, but Maine keeps the original, so you run two companies: the new one files Idaho's Annual Report (no fee), and the original keeps Maine's Annual Report.
How do I withdraw from Idaho later?
Maine companies leave by filing a Withdrawal of Foreign Registration Statement; until then, Idaho's report stays due alongside Maine's filings.
