How to start an LLC in Connecticut, step by step

1. Choose and check your LLC name. Your name must be unique in Connecticut and include "LLC" or "Limited Liability Company." Search the Connecticut Secretary of the State business database to confirm it's available, and grab the matching domain while you're at it.
2. Appoint a registered agent. Every Connecticut LLC needs a registered agent with a physical address in the state to receive legal mail. You can be your own agent or hire a service; here's what a registered agent is and how to choose.
3. File your Certificate of Organization. Submit the formation document to the Connecticut Secretary of the State, online or by mail, and pay the roughly $120 fee. Approval typically takes a few business days online.
4. Create an operating agreement. This internal document sets out ownership and how the LLC is run. It isn't always filed with the state, but it's strongly recommended even for single-member LLCs.
5. Get an EIN from the IRS. This free federal tax ID lets you open a business bank account, hire employees, and file taxes. Learn what an EIN is and how to apply in minutes.
6. Handle licenses, permits, and taxes. Depending on your industry and city, you may need local business licenses and a seller's permit for sales tax. See how to register a business for the full sequence.

Ongoing requirements for a Connecticut LLC

Forming the LLC is a one-time step; staying in good standing is ongoing. Connecticut requires an annual report (about $80) due by the anniversary each year. Missing a required filing can lead to late fees or administrative dissolution, so calendar every deadline the moment you form.

Tip: Open a dedicated business bank account as soon as your Connecticut LLC is approved and your EIN is issued. Keeping business and personal money separate is what actually preserves the liability protection an LLC provides.

Should you form your LLC in Connecticut or another state?

If you live and do business in Connecticut, forming here is almost always the right choice. Forming in a "cheaper" or more famous state usually backfires, because you'll still have to register as a foreign LLC in Connecticut anyway, which means paying two sets of fees and maintaining two registered agents. For the bigger picture, read what an LLC is and whether an LLC is right for you versus staying a sole proprietor.
