How Montana companies register with Idaho

We prepare and file the registration
It names us as your Idaho registered agent, with your Montana name and formation date. If Idaho wants the Montana certificate, it is ordered first. After approval, your Montana corporation is registered with Idaho.

Your Montana name and Idaho's rules

If Idaho's records show it taken, you can use an alternate name for the Montana company. We search Idaho's records for Montana's name on file before anything is filed.

Agents: Idaho and Montana

Montana and Idaho both call it a registered agent. Your current registered agent stays for Montana; ours takes Idaho's papers and notices.

Staying in good standing in Montana and Idaho

Each year your corporation files Montana's Annual Report (no fee) and Idaho's Annual Report (no fee). With our $149 registered agent renewal, Montana plus Idaho comes to $149 a year. The new registration does not replace any home-state filing.

LLC or corporation, Montana to Idaho

An LLC formed in Montana files its own registration with Idaho ($103.50 in state fees, the same, plus the Certificate of Existence ($5)). After that come Montana's Annual Report ($20) and Idaho's Annual Report (no fee). See the LLC filing.

Questions Montana owners ask about Idaho

Does my Montana company need to register in Idaho?

Yes, once a Montana business operates there; Idaho registers it as a foreign corporation.

Is this a certificate of authority?

Idaho calls it registration for Montana corporations; other states say certificate of authority.

How much does the Idaho registration cost?

$302.50 at checkout; Idaho may also want Montana'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 Montana's certificate if Idaho asks for it. Paid expedite: $40.

What are the yearly costs for Montana and Idaho?

$149 a year: our $149 registered agent renewal, nothing to Montana and nothing to Idaho for the yearly reports.

Does Idaho require a registered agent?

Yes: the Montana registered agent stays, and ours covers Idaho for year one, with a street address there.

Will Idaho accept my Montana name?

Yes, if no company there has it; if one does, it uses an alternate name there and keeps its Montana name at home.

Can I form a new Idaho corporation instead?

Yes, but Montana keeps the original, so you run two companies: the new one files Idaho's Annual Report (no fee), and the original keeps Montana's Annual Report.

How do I withdraw from Idaho later?

Montana companies leave by filing a Withdrawal of Foreign Registration Statement; until then, Idaho's report stays due alongside Montana's filings.
