What You'll Need to File

Connecticut's Certificate of Organization form is short — most of the effort is in having the right information ready before you sit down at Business.CT.gov:

  • 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.
  • Registered agent name and Connecticut street address — from Step 2.
  • Management structure — whether the LLC will be member-managed (owners run it) or manager-managed (designated managers run it).
  • Organizer's name and address — 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 your LLC's information — name, principal office address, registered agent, and management structure.
  • Review and submit — the system checks your name for distinguishability automatically as part of the filing.
  • Pay the $120 fee by credit card — online approval typically takes 2–3 business days.
  • 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.

Paper filings take significantly longerWhile Connecticut still accepts paper filings for the Certificate of Organization, processing takes roughly 1–2 weeks versus 2–3 business days online. If you're in a hurry, file online and consider the $50 expedited-processing add-on for 24-hour turnaround.

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.
