CO Registered Agent.org Review (2026)

CO Registered Agent.org charges $99 a year for Colorado registered agent service, with the same $99 at renewal. The plan includes an in-state street address for the registered office and online scans of legal papers served on the company. The company also forms a Colorado LLC for $199 plus the state fee, counting the first year of agent service in that price. It also handles foreign registration in Colorado at $199 plus the state fee. Score note: a good match for a Colorado-only company that wants a flat agent price and files its own periodic report.

The $99 plan, line by line

For $99 a year, CO Registered Agent.org acts as the Colorado registered agent. You receive an in-state street address for the registered office, and papers served on the company are scanned and posted to your account. Renewal holds at $99.

Using CO Registered Agent.org to form a Colorado LLC

CO Registered Agent.org prepares and files the formation document for $199; the state's filing fee is billed separately. Year one of registered agent service comes with it, and the agent runs $99 a year afterwards. The EIN application is a $99 extra, though the IRS charges nothing for an EIN.

Later, Colorado asks for the periodic report every year, due last day of the entity's anniversary month with a $25 fee. CO Registered Agent.org does not file it, so it stays on your list.

Bringing an existing company into Colorado with CO Registered Agent.org

CO Registered Agent.org sends the registration to the state for $199, and Colorado's $100 fee is added. A year of registered agent service rides along.

Where CO Registered Agent.org stands against Mainstay Filing

Agent service alone adds up to $297 over three years at CO Registered Agent.org and $447 at Mainstay Filing, a $150 spread. Mainstay Filing runs a single agent plan across all fifty states and scans the first three government mailings a year free. Mainstay Filing's formation package costs $199 a year and adds the periodic report, while CO Registered Agent.org's LLC route totals $397 over three years with the agent but no report filing. Colorado Registered Agent.co is the other Colorado agent on the card; it charges the same $99 a year, and the two sit close together.
