The 4 steps in Connecticut
Pick a name that works in Connecticut
Your name must be distinguishable from other Connecticut businesses and include “LLC,” “L.L.C.,” or “Limited Liability Company.” A name reservation costs $60 if you want to hold one.
File the paperwork
Connecticut calls the formation document a Certificate of Organization. You file it on Business.CT.gov, which also handles the required appointment of your statutory (registered) agent. The filing fee is $120. Also write a simple operating agreement — it's free, and it keeps your liability protection clear.
Get your free EIN
Apply at IRS.gov and get your Employer Identification Number immediately, for free. You'll need it for taxes and your business bank account.
Open a business bank account
Bring your approved Articles of Organization, EIN, and operating agreement. Keeping business money separate is what makes the liability protection hold.
Optional: name a registered agent service
Every Connecticut LLC needs a registered agent with a physical address in the state. You can be your own for free — or pay a service to keep your address private. Learn how registered agents work.
Connecticut calls the registered agent a “statutory agent.” Same role, different name.
File directly with the Connecticut Secretary of the State (Business.CT.gov).
