Colorado Registered Agent.co Review (2026)

With Colorado Registered Agent.co, Colorado 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 Colorado 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 Colorado, for $199 plus the state fee. The short version: it works well for a company that stays in Colorado, wants one agent price and doesn't mind filing its own periodic report.

What you get for $99 a year

For $99 a year, Colorado Registered Agent.co will be your Colorado registered agent. You get a registered office address in the state, and anything served on the company is scanned and waiting in your online account. When you renew, it's still $99.

How Colorado Registered Agent.co compares with Mainstay Filing and our other picks

If you only want the agent, three years cost $297 with Colorado 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 periodic report; forming through Colorado Registered Agent.co comes to $397 across three years, agent included, but report filing isn't part of it. CO Registered Agent.org, the other Colorado agent we picked, charges the same $99 a year, so the two end up close.
