Connecticut Registered Agent.co Review (2026)

Connecticut Registered Agent.co takes on the Connecticut 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.

Connecticut 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.

Connecticut Registered Agent.co will not file the annual report for you. In Connecticut it comes around every year, due on or before March 31, and the state bills $80, so keep it on your list.

Connecticut Registered Agent.co files the state registration for $199, with Connecticut's $120 fee added. Year one as your registered agent is covered. You bring certificate of existence (certificate of good standing) from the state of formation, dated within 90 days.

Agent service alone costs $297 over three years with Connecticut 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 annual report off your list; the Connecticut Registered Agent.co route totals $397 over three years with the agent but without report filing. CT Registered Agent.org, the other Connecticut agent we grade, charges the same $99 a year, and the two grades sit close together.
