Form in your home state if you operate locally

Unless you have investors or specific legal needs, forming your LLC in Connecticut (where you do business) is simpler and cheaper than Delaware or Wyoming — you avoid registering as a foreign LLC in two states.

Step-by-Step: Forming a Connecticut LLC

1

Choose a name for your LLC

Your LLC name must be unique in Connecticut and must include "Limited Liability Company," "LLC," or "L.L.C." Search the Connecticut Secretary of State's business name database before filing to confirm availability. You can typically reserve a name for 30–120 days for a small fee.

2

Appoint a registered agent

Every Connecticut LLC must have a registered agent — a person or company with a physical Connecticut address available during business hours to receive legal notices and state correspondence. You can serve as your own registered agent, or hire a registered agent service ($50–$150/year) for privacy and reliability.

3

File your Certificate of Organization

Submit your Certificate of Organization to the Connecticut Secretary of State along with the $120 filing fee. Standard processing takes approximately 5 business days. Expedited processing is available: 2.

4

Create an Operating Agreement

An Operating Agreement governs how your LLC is managed, how profits are split, and what happens if a member leaves. Connecticut may not require one, but having one is strongly recommended — it protects your limited liability status and prevents disputes.

5

Get an EIN from the IRS

Apply for a free Employer Identification Number (EIN) at irs.gov/ein. You'll need it to open a business bank account, hire employees, and file taxes. The application takes about 10 minutes and your EIN is issued immediately online.

6

Open a business bank account

Keep business finances strictly separate from personal accounts. Commingling funds is one of the most common reasons courts "pierce the corporate veil" and hold LLC members personally liable. Bring your EIN, Articles of Organization, and Operating Agreement to the bank.

7

Get business licenses and permits

Depending on your industry and location, you may need federal, state, or local business licenses. Check with your city and county clerk's office and the Connecticut state licensing portal for requirements specific to your business type.

8

Stay compliant after formation

File your annual report and pay the $80 annual fee any state and local tax filings.

Connecticut requires an annual report every year — no biennial option.

Can I be my own registered agent in Connecticut?

The tradeoff: your address becomes part of the public record. Many LLC owners use a registered agent service ($50–$150/year) for privacy and to ensure no legal notices are missed.
What taxes does a Connecticut LLC pay?
A Connecticut LLC is a pass-through entity by default — the LLC itself pays no federal income tax. Profits and losses pass through to the members' personal tax returns. Connecticut state taxes may include: annual report fee ($80), and standard state income tax on your share of LLC profits. Multi-member LLCs file a partnership return (Form 1065); single-member LLCs file on Schedule C.

Registered agent — don't skip this

Your registered agent's address is publicly listed in the state business registry. Using a commercial service keeps your home address off public records and ensures no lawsuit notices are missed when you're away.
