What triggers foreign qualification in Connecticut?

  • Physical office or place of business
  • Employees working in the state

Important to know

  • The annual report is due March 31 on a fixed calendar, not on the registration anniversary, so an LLC registering in February files within weeks.
  • Penalties continue for each year or part of a year of unregistered operation.
What does NOT require registration in Connecticut 12 activities

Connecticut carves 12 activities out by statute. On their own, none of them requires a foreign LLC to register.

  • Maintaining accounts in financial institutions
  • Maintaining offices or agencies for the transfer, exchange and registration of the company's securities, or maintaining trustees or depositories for them
  • Selling through independent contractors
  • Soliciting or obtaining orders by any means, if the orders require acceptance outside Connecticut before they become contracts
