How to Start an LLC in Connecticut: Complete 2026 Guide

How to Form an LLC: Step-by-Step

1. 1

   Choose Your Connecticut LLC Name

   Your LLC name must include 'LLC' or 'Limited Liability Company' and be distinguishable from existing Connecticut business names. Search available names using the Connecticut Secretary of State's business entity database to ensure your preferred name isn't already taken.

   Pro tip: Reserve your chosen name for 120 days by filing a Name Reservation Application with a $30 fee if you need time to prepare your other documents.
2. 2

   Designate a Connecticut Registered Agent

   Connecticut requires all LLCs to maintain a registered agent with a physical Connecticut address to receive legal documents and state correspondence. You can serve as your own registered agent if you have a Connecticut address, or hire a professional registered agent service.

   Pro tip: Professional registered agents ensure you never miss important legal documents and provide privacy by keeping your home address off public records.
3. 3

   File Connecticut Articles of Organization

   Submit your Articles of Organization to the Connecticut Secretary of State online through their business portal or by mail. The filing fee is $120, and processing typically takes 5 business days for standard filing.

   Pro tip: File online for faster processing and immediate confirmation of submission - you'll receive your Certificate of Organization electronically.
4. 4

   Create an LLC Operating Agreement

   While Connecticut doesn't legally require an operating agreement, creating one protects your limited liability status and establishes management structure, profit distribution, and member responsibilities. This document is especially crucial for multi-member LLCs.

   Pro tip: Even single-member LLCs benefit from operating agreements as they demonstrate separation between personal and business activities to courts and creditors.
5. 5

   Obtain Your Federal EIN

   Apply for an Employer Identification Number (EIN) directly through the IRS website at no cost. Your Connecticut LLC needs an EIN to open business bank accounts, file tax returns, and hire employees, even if you're a single-member LLC.

   Pro tip: Apply for your EIN immediately after receiving your Certificate of Organization - you'll need both documents to open a business bank account.
6. 6

   Open a Business Bank Account

   Connecticut law requires LLCs to maintain separate business finances to preserve limited liability protection. Bring your Certificate of Organization, EIN confirmation letter, and operating agreement to open your business bank account.

   Pro tip: Shop around for business banking options - many Connecticut banks offer special programs and fee waivers for new small businesses.

   Obtain Required Business Licenses

   Depending on your business type and location, you may need federal, state, or local licenses and permits. Check with Connecticut's Department of Consumer Protection and your local municipality for industry-specific requirements.
