Idaho Corporation Foreign Registration in Missouri
Missouri registers a corporation from Idaho as a foreign corporation on Form Corp 42, with $155 in state fees. Missouri also asks for Idaho's Certificate of Existence ($10), no older than 60 days. We file it with the Secretary of State, Corporations Division using your Idaho records and act as your registered agent there for the first year.

How Idaho companies register with Missouri
Order the Idaho certificate
The Certificate of Existence ($10) is ordered from Idaho separately; it is not part of our Missouri order. Missouri accepts it within 60 days of Idaho'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 Idaho name and formation date and the certificate attached. Once Idaho's certificate is in hand, Missouri's filing goes in. Once Missouri approves it, the Idaho company can do business there.

Questions Idaho owners ask about Missouri
Does my Idaho company need to register in Missouri?
Yes, once an Idaho 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 Idaho corporations once the form is approved.
How much does it cost to register an Idaho corporation in Missouri?
$354 at checkout plus $10 to Idaho for the Certificate of Existence, $364 in all (checkout is $155 in state fees plus our $199).
Do I need Idaho's certificate of good standing?
Yes: Missouri wants Idaho's Certificate of Existence ($10), no more than 60 days old at filing.
What are the yearly costs for Idaho and Missouri?
Our registered agent renewal ($149 a year), Idaho's report (no fee) and Missouri's report ($15, every two years).
What if I don't register with Missouri?
An Idaho 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 Idaho registered agent stays, and ours covers Missouri for year one.
Can I form a new Missouri corporation instead?
Yes, but Idaho keeps the original, so you run two companies: the new one files Missouri's Corporate Registration Report ($15), and the original keeps Idaho's Annual Report.
How do I withdraw from Missouri later?
Idaho companies leave by filing an Application for Certificate of Withdrawal; until then, Missouri's report stays due alongside Idaho's filings.
