Idaho LLC Foreign Registration in Montana
Montana registers an LLC from Idaho as a foreign LLC on an online registration (no form number), with $70 in state fees. Montana needs nothing from Idaho: no Certificate of Existence. We file it with the Secretary of State, Business Services using your Idaho records and act as your registered agent there for the first year.

How Idaho companies register with Montana
We prepare and file the registration
It names us as your Montana registered agent, with your Idaho name and formation date. Nothing has to come from Idaho first, so the Montana filing can go in right away. After approval, your Idaho LLC is registered with Montana.
Will your Idaho name work for Montana?
We search Montana's records for Idaho's name on file before anything is filed.
Agents: Montana and Idaho
Idaho and Montana both call it a registered agent. Montana papers come to us; Idaho's agent is unchanged.
Yearly filings: Montana and Idaho
Each year your LLC files Idaho's Annual Report (no fee) and Montana's Annual Report ($20). With our $149 registered agent renewal, Idaho plus Montana comes to $169 a year. Both states' filings stay current side by side.
LLC or corporation, Idaho to Montana
A corporation formed in Idaho files its own registration with Montana ($70 in state fees, the same). After that come Idaho's Annual Report (no fee) and Montana's Annual Report (no fee). See the corporation filing.
The other way: Montana into Idaho
An LLC formed in Montana that registers with Idaho files Idaho's registration (no form number) with $103.50 in state fees, plus the Certificate of Existence ($5) dated within 90 days. See that filing.
Common questions: Idaho to Montana
Does my Idaho company need to register in Montana?
Yes, once an Idaho business operates there; Montana does not count a one-off deal finished within 30 days.
How much does it cost to register an Idaho LLC in Montana?
$269 at checkout, with nothing to pay Idaho.
Do I need Idaho's certificate of good standing?
No, Montana takes the registration without it.
What are the yearly costs for Idaho and Montana?
$169 a year: our $149 registered agent renewal, nothing to Idaho and $20 to Montana for the yearly reports.
What if I don't register with Montana?
An Idaho company cannot sue in court there until it registers, and Montana can add a penalty of $5 a day, up to $1,000 a year.
Does Montana require a registered agent?
Yes: the Idaho registered agent stays, and ours covers Montana for year one.
Can I form a new Montana LLC instead?
Yes, but Idaho keeps the original, so you run two companies: the new one files Montana's Annual Report ($20), and the original keeps Idaho's Annual Report.
How do I withdraw from Montana later?
Idaho companies leave by filing an Application for Certificate of Withdrawal (foreign limited liability company); until then, Montana's report stays due alongside Idaho's filings.
