Colorado Registered Agent.co Review (2026)

Colorado Registered Agent.co takes on the Colorado registered agent job at $99 a year. That includes a registered office address in the state, plus scans of anything served on the company waiting in your account. Renewal does not change it: $99 again.

Colorado Registered Agent.co files the formation paperwork for $199, plus the state's filing fee. Your first year as registered agent comes with it; after that the agent is $99 a year. An EIN application adds $99, although the IRS issues EINs free.

Colorado Registered Agent.co will not file the periodic report for you. In Colorado it comes around every year, due last day of the entity's anniversary month, and the state bills $25, so keep it on your list.

Colorado Registered Agent.co files the state registration for $199, with Colorado's $100 fee added. Year one as your registered agent is covered.

Agent service alone costs $297 over three years with Colorado Registered Agent.co and $447 with Mainstay Filing, so $150 separates them. Mainstay Filing runs one agent plan that is valid in all fifty states and scans the first three government mailings a year free. The Mainstay Filing package is $199 a year and takes the periodic report off your list; the Colorado Registered Agent.co route totals $397 over three years with the agent but without report filing. CO Registered Agent.org, the other Colorado agent we grade, charges the same $99 a year, and the two grades sit close together.
