How to start a Connecticut LLC in 6 steps

Name it, appoint a Connecticut statutory agent, file the Certificate of Organization ($120), write an operating agreement, get a free EIN, then file the $80 annual report between January 1 and March 31.

Name your Connecticut LLC

The name must be distinguishable from other Connecticut entities and include an LLC designator. Check it in the Connecticut business search before filing. If you want to hold a name before you are ready, a reservation costs $60, which is on the expensive side, so most people just file.

Appoint a Connecticut statutory agent

Connecticut calls the registered agent a statutory agent, and the appointment is built into the Certificate of Organization rather than being a separate filing. The agent needs a Connecticut address. Choose carefully: changing the agent, or the agent's address, costs $50 each time. Northwest includes agent service free the first year with their $39 filing.

File the Certificate of Organization

File at business.ct.gov, the state's one-stop portal. The fee is $120 and it covers the statutory agent appointment. Filing online is faster than paper and lets you save your progress before submitting.

Write an operating agreement

Connecticut does not require one, but write it anyway. It sets out ownership, management, and who can sign, it backs up your liability protection, and banks usually ask for it at account opening. A simple template covers a single-owner courier business.

Get a free EIN from the IRS

Your EIN is free at irs.gov and takes about ten minutes. You need it for the business bank account, contracts, and hiring. Never pay a third-party site for one.

File the $80 annual report between January 1 and March 31

Starting the year after you form, Connecticut requires an annual report, $80, filed online only through your Business.CT.gov account, in the January 1 to March 31 window. Miss it and your LLC drifts out of good standing, which shows up when a client or bank checks you.
