Colorado Registered Agent.co Review (2026)

Colorado Registered Agent.co offers Colorado registered agent service at $99 a year, the same $99 at renewal. The plan provides a street address in the state for the registered office, and legal papers served on the company are scanned to an online account. It will also form a Colorado LLC for $199 plus the state fee, with the first year of agent service included. It registers out-of-state companies in Colorado for $199 plus the state fee. The finding: sound for a Colorado-only company that wants a fixed agent charge and is prepared to file its own periodic report.

What the $99 yearly charge covers

Colorado Registered Agent.co acts as the Colorado registered agent for $99 a year. The company receives a street address in the state for its registered office, and papers served on it are scanned to an online account. Renewal leaves the charge at $99.

Forming a Colorado LLC through Colorado Registered Agent.co

Colorado Registered Agent.co files the formation document for $199; the state's filing fee is billed separately. Year one as your registered agent is included, and the agent is $99 a year after that. The EIN application is $99 extra, though the IRS issues the number at no cost.

Colorado requires the periodic report every year, due last day of the entity's anniversary month with a $25 state fee. Colorado Registered Agent.co does not prepare it, so the owner must.

Colorado Registered Agent.co against Mainstay Filing and the other providers

On the agent service alone, Colorado Registered Agent.co totals $297 across three years against $447 for Mainstay Filing, a margin of $150.

CO Registered Agent.org, the other Colorado agent heard on this site, charges the same $99 a year, and the two finish near each other.
