How Do You Start an LLC in Connecticut?

Filing in Connecticut costs $120 in state fees. Connecticut publishes no standard processing time, so plan around the filing itself rather than a promised turnaround. You'll file Articles of Organization, appoint a registered agent, and complete any state-specific requirements before opening for business.

That is the filing fee alone. For the first-year and five-year totals, see Connecticut LLC cost.
