Colorado Registered Agent.co Review (2026)

Colorado Registered Agent.co serves as your Colorado registered agent for $99 a year. The plan supplies an in-state street address for the registered office and scans legal papers served on the company to your online account. At renewal the price stays $99.

Colorado Registered Agent.co files the formation document for $199, and the state's filing fee goes on top. The first year of registered agent service is included; after that the agent is $99 a year. An EIN application costs $99 extra, although the IRS issues EINs free.

Colorado expects 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 file it, so that job stays with you.

Colorado Registered Agent.co files the registration with the state for $199, plus Colorado's $100 fee. A year of registered agent service is part of it.

For the agent alone, Colorado Registered Agent.co comes to $297 over three years and Mainstay Filing to $447, a gap of $150. Mainstay Filing sells one agent plan for all fifty states and scans the first three government mailings a year free. Mainstay Filing's formation package is $199 a year and includes the periodic report; Colorado Registered Agent.co's LLC route comes to $397 over three years with the agent but without report filing. CO Registered Agent.org, the other Colorado agent on our list, charges the same $99 a year, and the two finish close together.
