Best LLC Formation Services in Connecticut

Connecticut is one of the few states that allows Series LLCs, letting you create separate liability-protected series under a single parent LLC. This is useful if you hold multiple rental properties or run distinct business lines.

Unlike neighboring New York, Connecticut has no publication requirement. New York LLCs can spend $1,000+ publishing in newspapers after formation. You skip that entirely here.

Connecticut does not offer anonymous LLCs. Your name and address as an organizer will appear on the public Certificate of Organization filed with the Secretary of the State. If privacy matters, you can list your formation service as the organizer instead.

The state charges a $60 name reservation fee that holds your LLC name for 120 days. That is double what most states charge for name reservations, so only reserve if you are not ready to file immediately.

1. Get your EIN from the IRS. This is free and can be done online at irs.gov. You need it to open a business bank account and hire employees.
2. Register with the Connecticut Department of Revenue Services (DRS) if you will collect sales tax (6.35% state rate) or have employees. You can register online through the DRS myconneCT portal.
3. File your Annual Report by March 31 each year with the Secretary of the State. The fee is $80. There is no late fee, but failing to file for over a year puts your LLC at risk of administrative dissolution.
4. File a federal Beneficial Ownership Information (BOI) report with FinCEN. LLCs formed in 2024 or later must file within 90 days of formation. Existing LLCs must file by the current FinCEN deadline.
5. Draft an operating agreement. Connecticut does not require one by law, but banks often ask for it when opening a business account, and it protects your limited liability status in court.
6. Check whether your specific industry requires a state or local license or permit. Connecticut has no general business license, but occupations like contractors, food service, and healthcare each have their own licensing boards.

• $120 Reinstatement Fee - If your LLC is dissolved for missing annual reports, you will pay $120 to reinstate it, the same as forming a new LLC from scratch.
