Connecticut Registered Agent.co Review (2026)

Connecticut Registered Agent.co sells Connecticut registered agent service for $99 a year, the same $99 at renewal. That buys an in-state street address for the registered office and online scans of legal papers served on the company. Forming a Connecticut LLC through it costs $199 plus the state fee, and the first year of agent service is included. For foreign registration in Connecticut it charges $199 plus the state fee. Verdict: a sound choice for a Connecticut-only company that wants a fixed agent price and will file its own annual report.
