- Just pricier: Illinois ($375), Washington ($390).
- Full table: all 51 states ranked by 3-year state fees — including where the ranking flips once you add a professional registered agent.
Registered agent (Connecticut)
- Statutory/registered agent required; appointment included in Certificate of Organization filing.
Put the agent next to the state's own bill: three years of Connecticut state fees is $360, while the cheapest provider path in our national 3-year comparison runs $289 (Formation $39 (RA Y1 included)) and the most expensive runs $747 (Basic $0 + RA $249/yr) — a $458 spread for the same statutory job. On the cheapest path the service, not Connecticut, is about 45% of your three-year outlay. Choosing the agent well is usually a bigger lever than choosing the state.
Gotchas (fact-based)
- Annual report must be filed online in the Jan–Mar window; missing filings risk administrative dissolution.
Who Connecticut is for / not for
Often a fit when…
- Domestic LLCs wanting a mid-cost Northeast formation with a predictable annual SOS report.

Common questions about Connecticut LLC cost
How much does it cost to form an LLC in Connecticut?
$120 to Connecticut Secretary of the State / Business.CT.gov for the formation filing. Certificate of Organization including appointment of statutory agent; $120 (CGS §34-243u; business.ct.gov fee schedule). That is the state charge only. A formation service is a separate bill on top: Formation $39 (RA Y1 included) works out to $39 in year one, versus $249 on the most expensive path we track.
What are the ongoing Connecticut LLC fees after year one?
$80 for the Annual Report, due Annually online between January 1 and March 31. Fee $80 for years on/after July 1, 2020 (CGS §34-243u(a)(15)). Recurring state charges are what make a low formation fee misleading — they are the reason this site models three years instead of one.
What does a Connecticut LLC really cost over three years?
$360 in Connecticut state fees, plus whatever your provider charges. With the cheapest tracked path that is $649 all-in over three years; with the most expensive it is $1,107 — a $458 difference that has nothing to do with Connecticut.
Do I need a registered agent in Connecticut?
Yes. Statutory/registered agent required; appointment included in Certificate of Organization filing. Confirm Connecticut's DIY-versus-commercial agent rules with Connecticut Secretary of the State / Business.CT.gov before you file — a home address here becomes public record. On the money side, the four providers tracked here charge $0–$249 in year one for formation plus the agent, then $125–$249 a year in agent renewal after that — separate from every Connecticut figure above.
Is Connecticut a cheap state to form an LLC?
On charter cost alone, Connecticut ranks #33 of 51 at $360 over three years, against a $35 floor and a $2,510 ceiling. But cheapest charter is not the same as cheapest outcome: if you operate somewhere else you will likely foreign-qualify there and pay that state's fees and taxes too. See the full 3-year state fee ranking for the comparison.
