Montana Registered Agent.co Review (2026)

With Montana Registered Agent.co, Montana registered agent service is $99 a year, the same $99 at renewal. You get an in-state street address for your registered office, and legal papers served on the company are scanned to your account. Want to start a Montana LLC with it? That's $199 plus the state fee, and your first year of agent service is included. It also registers outside companies in Montana, for $199 plus the state fee. The short version: it works well for a company that stays in Montana, wants one agent price and doesn't mind filing its own annual report.

If you only want the agent, three years cost $297 with Montana Registered Agent.co and $447 with Mainstay Filing, a difference of $150. Mainstay Filing has one agent plan that works in every state and scans the first three government mailings a year free. Mainstay Filing's package is $199 a year and includes the annual report; forming through Montana Registered Agent.co comes to $397 across three years, agent included, but report filing isn't part of it. Registered Agent MT.org, the other Montana agent we picked, charges the same $99 a year, so the two end up close.
