What you get for $99 a year

The plan is simple: a Colorado street address for the registered office and scans of served papers, for $99 a year. Renewal is the same $99.

CO Registered Agent.org LLC formation

CO Registered Agent.org prepares and files the Articles of Organization for $199 plus Colorado's $50 filing fee. The first year of registered agent service is included, then the agent is $99 a year. An EIN application is a $99 add-on; the IRS issues EINs for free.

You will still owe the periodic report every year, due last day of the entity's anniversary month; CO Registered Agent.org does not list it in its prices.

Foreign registration with CO Registered Agent.org

For a company formed elsewhere, CO Registered Agent.org files the Statement of Foreign Entity Authority with the Colorado Secretary of State, Business Program for $199 plus the state's $100 fee. A year of registered agent service comes with it.

Compared with the other picks

CO Registered Agent.org saves $150 over three years against Mainstay Filing ($297 vs $447). Mainstay's price is the same in every state and scans the first three government mailings a year free. For a new LLC, Mainstay Filing charges $199 a year and files your periodic report, while CO Registered Agent.org costs $397 over three years with the agent but no report filing. Colorado Registered Agent.co is the other Colorado agent we rank, at the same $99; the two finish close.
