Ready to start your LLC?

Start my LLC
✅ 1. Choose a Unique LLC Name

Your LLC name must be unique in Connecticut—no two businesses can share the same name.

Do a Name Search: Use the Business Records Search to make sure your preferred name is available.

Follow Naming Rules: Connecticut has guidelines on acceptable LLC names. We double-check this for Filing Fox clients so your paperwork sails through approval.

✅ 2. Appoint a Registered Agent in Connecticut

A Registered Agent is required for every LLC. This person or service accepts legal mail and official documents for your business.

Your options:

  • Be your own Registered Agent (your address becomes public)
  • Have a friend or family member do it (their address becomes public)
  • Use a professional Registered Agent service—like Filing Fox—to keep your private address off public records and receive documents securely

We’ll scan any mail received and make it available to you online—no surprises.

✅ 3. File Your Certificate of Organization

This is the official form that registers your LLC with the state.

  • Fee: $120 (one-time)
  • File Online: About 2–3 business days
  • File by Mail: About 7–10 business days plus mailing time

Filing Fox can handle this for you, ensuring everything is accurate and filed on time. DIY filings often get delayed over simple mistakes—don’t let that be you.

✅ 4. Create an LLC Operating Agreement

While Connecticut doesn’t legally require an Operating Agreement, it’s strongly recommended. This document outlines who owns the LLC, how it’s managed, and what happens if a dispute arises.

  • Banks often ask for it to open a business account.
  • Keep a signed copy with your records—do not file with the state.

✅ 5. Get an EIN from the IRS

Your Employer Identification Number (EIN) is like a Social Security Number for your business. You’ll need it to:

  • Open a business bank account
  • Hire employees
  • File federal and state taxes

Good news: An EIN is completely free through the IRS. You can get one online in about 15 minutes if you have an SSN or ITIN.

Not sure how? Filing Fox can guide you step by step.

What to Do After Your LLC Is Approved

  • Open a Business Bank Account
    Keep your personal and business finances separate — it’s crucial for protecting your personal assets.
  • Register for Taxes
    Connecticut doesn’t have a general state business license, but you’ll need to register with the Department of Revenue and get a State Tax ID Number. Local licenses may be required too.
  • File Your Annual Report
    Every Connecticut LLC must file an Annual Report by March 31st each year — the fee is $80. Staying compliant keeps your business in good standing.
