What catches people out in Montana
- Operating in another state means another full set of these. A foreign qualification is a second registration: its own registered agent, its own report, its own fee. It is not an extension of your Montana filing.
What happens if you miss it
Not in good standing; eventual dissolution. The end state is administrative dissolution. That is the part worth understanding: an administratively dissolved LLC stops existing as a legal entity, and the liability protection you formed it for stops with it. In some states that is applied retroactively. The late fee is annoying; losing the shield on a company that holds an asset is the actual risk.
Montana accepts filings online at https://sosmt.gov/business/. You can absolutely do this yourself — most people can. The difficulty is never one filing, it is remembering the fourth one across three states in a year.
Doing it yourself vs having it handled
One company in Montana and nothing else? File it yourself and set a calendar reminder. Our registered agent service is $99 a year if you want the address and the mail handled, and formation is $209 plus the state's $70.
Several companies, or any of them registered in more than one state, is a different problem. Autopilot is $3,500 a year and covers 15 company-state registrations: we are the agent, we track every obligation above, we file them, and if we miss one we pay the penalty and the reinstatement cost.

Find out what your companies actually owe
Type in your companies and we will show you every deadline, fee and obligation each one carries — including the ones that are not the annual report. Free, no account, and the answer appears on the page rather than in an email.
It computes your obligations from each state's published rules and the formation dates you give us. It does not contact Montana's registry, so it cannot tell you your current standing — we say so on the page too, because a tool that told you you were in good standing without having looked would be worse than no tool.
