Introduction to Forming an LLC in Connecticut

To form a Limited Liability Company (LLC) in Connecticut, one must understand its essential components and legal requirements. An LLC combines the liability protection of a corporation with the flexibility and tax advantages of a partnership.

Benefits of an LLC in Connecticut

  • Limited Liability Protection

  • Pass-Through Taxation

  • Operational Flexibility

Initial Considerations

  • Choose a Unique Name: Must comply with Connecticut naming rules.

  • Registered Agent Requirement: Must have a registered agent with a Connecticut address.

  • Articles of Organization: Necessary to file with the Connecticut Secretary of State.

Why You Should Consider Forming an LLC

Forming a Limited Liability Company (LLC) provides multiple benefits that make it an attractive business structure. Key reasons include:

  • Limited Liability Protection: Owners’ personal assets are protected from business debts and liabilities.

  • Pass-Through Taxation: LLCs generally avoid double taxation; profits and losses pass through to the owners’ personal tax returns.

  • Flexible Management Structure: LLCs offer flexibility in management structure, allowing members to choose member-managed or manager-managed options.

  • Less Compliance Requirements: Compared to corporations, LLCs have fewer ongoing formalities and reporting obligations.

  • Credibility and Professionalism: An LLC designation enhances business credibility, potentially attracting more clients and investors.

Step 1: Choose a Name for Your LLC

Selecting a suitable name for the LLC is crucial. It must comply with Connecticut state regulations and be distinctive enough to avoid confusion with existing entities.

  • Unique and Distinguishable: The name should be unique and clearly distinguishable from other registered businesses in the state database.

  • Inclusion of “LLC”: The chosen name must include “Limited Liability Company” or abbreviations like “LLC” or “L.L.C.”

  • Prohibited Terms: Avoid using terms that may mislead about the business’s purpose, such as “bank” or “insurance,” unless specific permissions are obtained.

  • Name Availability: Check the name’s availability using the Connecticut Secretary of State’s online database.

Step 2: Check Name Availability and Reserve Your LLC Name

Before filing, verify the desired LLC name’s availability through the Connecticut Secretary of State’s online database. Ensure the name is unique and adheres to state naming guidelines which prohibit similarities to existing entities or usage of restricted words. After confirmation:

  1. Go to the Connecticut Secretary of State’s website: Access the Business Services section.

  2. Perform a name search: Use the online tool to check availability.

  3. Reserve the Name:

    • Complete the Application for Reservation of Name.

    • Pay the required reservation fee.

  4. Confirmation: Receive a confirmation of name reservation.

Step 3: Designate a Registered Agent

A registered agent is required for all LLCs in Connecticut. This individual or entity will receive official documents and service of process on behalf of the LLC. The agent must:

  • Be a Connecticut resident or a business entity authorized to do business in the state.

  • Have a physical street address in Connecticut (P.O. Boxes are not acceptable).

The registered agent is crucial for legal compliance and ensuring timely receipt of important documents. The LLC may designate a member, manager, or a professional registered agent service to fulfill this role. Ensure the chosen agent consents to their designation.

Step 4: File the Certificate of Organization

Filing the Certificate of Organization is a crucial step when forming an LLC in Connecticut. The individual must complete and submit this document to the Connecticut Secretary of State.

Required Information:

  • LLC name

  • Principal office address

  • Registered agent’s name and address

  • Management structure

  • Name and address of at least one member or manager

Filing Methods:

  1. Online: Via the Connecticut Business One Stop website.

  2. Mail: Send the form to the Secretary of State’s office at P.O. Box 150470, Hartford, CT 06115-0470.

Processing times and fees vary, so reviewing the latest details on the official website is essential.

Step 5: Create an Operating Agreement

An operating agreement outlines the LLC’s management structure and operating procedures. It ensures all members are on the same page about the business’s rules and reduces future conflicts.

  • Details of Members:

    • Names and addresses

    • Initial capital contributions

  • Management Structure:

    • Member-managed or manager-managed
  • Voting Rights:

    • How decisions will be made
  • Profit Distribution:

    • How profits and losses will be allocated
  • Meetings:

    • Frequency and procedures
  • Dissolution Terms:

    • Process if the LLC must dissolve

Though not required by Connecticut law, it is highly advisable.

Step 6: Apply for an EIN (Employer Identification Number)

To operate legally as an LLC in Connecticut, an EIN is required. The EIN is assigned by the IRS and used for tax purposes.

  1. Visit the IRS Website: Navigate to the official IRS website.

  2. Apply Online: Use the EIN Assistant tool for a quick process. The online service is available Monday to Friday.

  3. Complete the Application:

    • Select “LLC” for entity type.

    • Provide business details (name, address, ownership details).

  4. Receive EIN: Immediately obtain your EIN upon completion.

  5. Record EIN: Keep the EIN safe for tax filings, opening a business bank account, and payroll setup.

Step 7: Comply with Other Tax and Regulatory Requirements

After forming an LLC in Connecticut, it is essential to comply with additional tax and regulatory necessities, such as:

  1. Obtain an EIN: Apply for an Employer Identification Number (EIN) from the IRS.

  2. Register for State Taxes: If applicable, register for Connecticut state taxes, including sales tax, withholding tax, or unemployment insurance tax.

  3. Local Business Licenses: Acquire necessary local business licenses or permits based on the city or county regulations.

  4. Annual Report: File an annual report with the Connecticut Secretary of State and pay associated fees.

  5. Industry-Specific Requirements: Comply with any industry-specific regulatory requirements or professional licenses.

Step 8: File an Annual Report

LLCs in Connecticut must file an annual report with the Secretary of State. The due date is based on the anniversary month of the LLC’s formation.


  1. Visit the Secretary of State’s website

    • Access the Business Services section.
  2. Locate the LLC Annual Report filing

    • This can be found under the “Business Filings” tab.
  3. Fill out the required information:

    • Ensure correct entry of the LLC name and registration number.
  4. Pay the filing fee

    • The current fee is $80 (subject to change).
  5. Submit the form electronically

    • An email confirmation will be sent.

Failure to file can result in penalties and possible dissolution of the LLC.

Step 9: Understand Connecticut’s Ongoing LLC Requirements

Connecticut LLCs must meet several ongoing requirements:

  • Annual Report: LLCs must file an annual report by March 31. The filing fee is $80.

  • Registered Agent: Maintain a registered agent within Connecticut.

  • State Taxes: File state taxes as required; LLCs are subject to business entity tax.

  • Records Maintenance: Retain accurate financial records and meeting minutes.

  • Licenses and Permits: Renew necessary local, state, and federal licenses.

  • Compliance: Adhere to state regulations and obligations, including employment laws.

By meeting these ongoing requirements, your LLC will remain compliant and in good standing with the state of Connecticut.
