From Idaho to Montana, step by step
We prepare and file the registration
It lists us as your Montana registered agent, next to your Idaho name and formation date. If Montana wants the Idaho certificate, it is ordered first. Once Montana approves it, the Idaho company can do business there.
Will your Idaho name work for Montana?
We check your exact Idaho name against Montana's records before filing.
Agents: Montana and Idaho
Idaho and Montana both call it a registered agent. Your current registered agent stays for Idaho; ours takes Montana's papers and notices.
Yearly filings: Montana and Idaho
Each year your corporation files Idaho's Annual Report (no fee) and Montana's Annual Report (no fee). With our $149 registered agent renewal, Idaho plus Montana comes to $149 a year. The new registration does not replace any home-state filing.
LLC or corporation, Idaho to Montana
An LLC formed in Idaho files its own registration with Montana ($70 in state fees, the same; no home-state certificate is needed). After that come Idaho's Annual Report (no fee) and Montana's Annual Report ($20). See the LLC filing.
