The Process

Five steps. No lawyer required.

Connecticut keeps this straightforward — get the order right and you're filed within a few weeks, not months.

01

Lock in your name

Must include "LLC" or "L.L.C." — search the Connecticut Secretary of the State's business database first, since a taken name is the #1 reason filings bounce.

02

Appoint your agent

Non-negotiable under Connecticut law. Needs a real street address, staffed during business hours — no P.O. boxes.

03

File your Certificate of Organization

Filed online or by mail with the $120 state fee. This is the step that makes it official.

04

Claim your EIN

Free straight from the IRS — you'll need it before a bank will let you open a business account.

05

Mark your calendar

Annual Report, $80, due every year by the anniversary date of formation — miss it and Connecticut can administratively dissolve your LLC.

Skip the paperwork chase.

Northwest handles all five steps above and includes your Connecticut registered agent free for year one.

DIY vs. Guided

Most Connecticut filings get rejected for the same three mistakes.

Wrong entity designator, missing registered agent info, and name conflicts account for most bounced filings. Here's what changes with a formation service handling it.

Questions

Connecticut LLC formation, answered.

How much does it cost to start an LLC in Connecticut?+
The state filing fee is a flat $120, paid once to the Connecticut Secretary of the State. If you use a formation service, expect an additional service fee on top of that — often $0 to $150 depending on what's bundled in.
How long does Connecticut LLC approval take?+
Standard processing runs 2–3 weeks once filed. Expedited processing is available for an extra fee if you need it faster.
Can I be my own registered agent in Connecticut?+
Yes, as long as you have a physical Connecticut street address and are available during business hours. Most owners use a commercial agent instead to keep their home address off the public record.
Do I need a lawyer to start an LLC in Connecticut?+
No. Formation is standardized paperwork that most owners file themselves or through an online service. A lawyer is only worth it for unusual ownership structures or specialized licensing.
Does Connecticut require an annual report or franchise tax for LLCs?+
Yes — Connecticut LLCs file an Annual Report, $80, due each year by the anniversary date of formation.
