What Connecticut charges you to register a foreign LLC and what it requires

If your LLC was formed elsewhere, you register it in Connecticut before doing business there. You hand the Foreign Registration Statement, Limited Liability to the Connecticut Secretary of the State, Business Services Division and pay $120. The filing needs certificate of existence (certificate of good standing) from the state of formation dated within 90 days.

Operating without registering may mean back fees covering the unregistered stretch.

Straight from the source: business.ct.gov (we looked on October 2026, so you can too)

Doing it alone

Go it alone and Connecticut still takes $280 over three years, and you complete every form yourself. A service charges $397 to $497 to take that over.
