Connecticut Registered Agent.co Review (2026)

Connecticut Registered Agent.co puts registered agent service in Connecticut at $99 a year, and the same $99 at renewal. You get an in-state street address for the registered office and online scans of papers served on the company. It will also form a Connecticut LLC for $199 plus the state fee, with the first agent year included. And it handles foreign registration in Connecticut for $199 plus the state fee. The desk's read: a good fit for a Connecticut-only company that wants a fixed agent price and will file its own annual report.
