CO Registered Agent.org Review (2026)

With CO Registered Agent.org, 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, CO Registered Agent.org 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.

Starting a Colorado LLC with CO Registered Agent.org

CO Registered Agent.org will file your formation paperwork for $199, and you pay the state's filing fee separately. Your first year as registered agent is included, and after that the agent is $99 a year. If you want them to apply for your EIN, that's $99 more, though the IRS gives EINs out free.

CO Registered Agent.org doesn't file the periodic report, so that one is yours. In Colorado it comes every year, by last day of the entity's anniversary month, and the state asks $25.

Bringing a company from another state into Colorado with CO Registered Agent.org

Registration with Colorado is $199 through CO Registered Agent.org, plus the state's $100. Your first year as registered agent comes with it.

How CO Registered Agent.org compares with Mainstay Filing and our other picks

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