What You'll Need to File

The published July 2024 Certificate of Organization asks for the LLC name, principal street and mailing addresses, agent details and signed acceptance, at least one manager/member’s name, title and addresses, entity email (or the no-email box), six-digit NAICS code, organizer name/signature and filing-party contact. Follow current online prompts or the current form; do not treat a generic management-mode checklist as the full published form. The LLC itself cannot act as its own organizer.

  • Your LLC's exact legal name — including the designator (LLC, L.L.C., etc.), confirmed available via Step 1.
  • Principal office address — where your LLC's main records and business are based; can be in or outside Connecticut.
  • Prepare the agent details, required address information and signed acceptance.
  • Prepare at least one manager/member’s name, title, business and residence addresses; follow the current published form or online prompts.
  • Organizer name/signature and filing contact — the person filing the paperwork (doesn't have to be an owner).
  • Payment method — the $120 fee is paid by credit card at the time of online filing.

How to File

  • Go to Business.CT.gov and create an account, then select "Start a New Business" → "Certificate of Organization" for a Limited Liability Company.
  • Enter the current form or portal fields, including principal/mailing addresses, agent acceptance, manager/member details, entity email or no-email selection, six-digit NAICS code and organizer information.
  • Review and submit — the system checks your name for distinguishability automatically as part of the filing.
  • Pay the $120 filing fee and check the current processing queue. An online $50 expedited option is available only when offered for the transaction.
  • Download your Acceptance Notice and stamped Certificate — this is your official proof of formation; you'll need it to open a business bank account and apply for an EIN.

Ahmad Adil's Take: Connecticut's online filing is reasonably quick for a state that still offers a paper option — 2–3 business days beats waiting on the mail. Run through the checklist above before you start the online form so you're not stopping mid-application to look something up. Save a PDF of your accepted Certificate the moment you get it; you'll need it again almost immediately for your EIN application and bank account setup.
