Route services for Connecticut

The order rests on five criteria set out in the method: three-year provider cost (35%), steps covered (27%), renewal fare, fit with Connecticut rules and fee labeling.

1. Mainstay Filing: best for an LLC that stays on the road without effort

Stop oneLeg one $199, later legs $199; state toll separate

Each renewal includes the annual report stop, and the state's $80 toll is billed at cost.

  • Leg one done for you: the formation is drafted and filed
  • Registered agent duty held through the year
  • The annual report drafted and sent in by Mainstay
  • The EIN application is part of the route
  • State tolls at cost, nothing added
