Why Form an LLC in Connecticut?
A Limited Liability Company (LLC) is one of the most popular business structures in the US — and Connecticut is a great place to form one. An LLC gives you personal liability protection, pass-through taxation, and flexible management structure without the complexity of a corporation.
The state filing fee in Connecticut is $120, paid to the Connecticut Secretary of State. This is a one-time formation cost — separate from any ongoing annual fees (see the sidebar).
Step-by-Step: How to Form Your Connecticut LLC
Choose Your LLC Name
Your name must be unique in Connecticut and include "LLC," "L.L.C.," or "Limited Liability Company." Search the Connecticut Secretary of State database to check availability before filing.
Appoint a Registered Agent
Required. Must have a CT address.
File Articles of Organization
Submit your LLC formation documents (Articles of Organization) to the Connecticut Secretary of State. You can typically file online. The filing fee is $120.
Create an Operating Agreement
Connecticut does not require an operating agreement by law, but it's strongly recommended. It outlines ownership percentages, voting rights, profit distribution, and management structure.
Get Your Free EIN from the IRS
An Employer Identification Number (EIN) is your LLC's federal tax ID — like a Social Security number for your business. Apply free at irs.gov. Takes about 10 minutes online.
Open a Business Bank Account
Keep your business and personal finances separate. You'll need your Articles of Organization (stamped by the state) and your EIN to open a business checking account.
Annual Requirements in Connecticut
Annual report required — $80/year
Keeping up with annual requirements is critical to keep your LLC in "good standing." If you miss renewals, your LLC can be administratively dissolved by the state, losing your liability protection.
Registered Agent Requirements
Required. Must have a CT address.
If you use a professional registered agent service, expect to pay $49–$299/year. Services like Northwest Registered Agent, ZenBusiness, and Registered Agents Inc. are popular options.
