How to Register an LLC in Connecticut

Registering a Limited Liability Company (LLC) in Connecticut involves several key operational steps. Following this process ensures compliance with state requirements and sets a strong foundation for your business.

Step 1: Choose a Name for Your LLC

  • Ensure the name is unique: The name must be distinguishable from other registered entities in Connecticut.
  • Include "LLC" or "Limited Liability Company": This designation is required to identify the business structure.
  • Check name availability: Use the Connecticut Secretary of State’s business name database to confirm your desired name is available.

Step 2: Designate a Registered Agent

Connecticut requires every LLC to appoint a registered agent with a physical address in the state. The registered agent receives legal and tax documents on behalf of the LLC.

Step 3: File the Certificate of Organization

  • Prepare the Certificate of Organization: This is the official formation document for your LLC.
  • File with the Connecticut Secretary of State: You can file online, by mail, or in person.
  • Pay the filing fee: As of 2026, the fee is $120. Confirm current fees on the Secretary of State website.

Step 4: Create an Operating Agreement

While not required by Connecticut law, an operating agreement is highly recommended. It outlines the ownership, management structure, and operational procedures of your LLC, supporting internal compliance and clarity.

Step 5: Obtain an EIN from the IRS

Apply for an Employer Identification Number (EIN) through the IRS website. This number is essential for payroll, tax reporting, and opening business bank accounts.

Step 6: Register for State Taxes and Permits

  • Register with the Connecticut Department of Revenue Services (DRS): If your LLC will collect sales tax, have employees, or be subject to other state taxes, register accordingly.
  • Check local licensing requirements: Depending on your business activities and location, you may need additional municipal permits or professional licenses.

Step 7: Maintain Compliance

  • File Annual Reports: Connecticut LLCs must file an annual report with the Secretary of State. The fee is currently $80, due annually by the end of the anniversary month of formation.
  • Keep accurate records: Maintain bookkeeping, payroll records, and meeting minutes as applicable.
  • Review insurance needs: Consider general liability, workers’ compensation, and other relevant insurance policies to protect your business.

Following these operational steps will help you successfully register and maintain your LLC in Connecticut. Always verify current fees and requirements with official state resources to ensure ongoing compliance.
