  1. Choose a Corporate Structure

    Incorporating means starting a corporation. If you want to form an LLC, please see "How to Form an LLC in Connecticut".

    Is your corporation for-profit or not-for-profit? If you are starting a nonprofit, please see "How to Start a Non-Profit Organization in Connecticut".

    C-Corp and S-Corp refer to taxation with the IRS, not to legal structures. Your corporation is taxed as a C-Corp unless you file an election to be taxed as an S-Corp (explained below).

  2. Check Name Availability

    The legal name of your corporation may not conflict with any other registered name. Check availability of your desired name by conducting a name search.

    Name Search:
    Name Reservation: Optional
    Suffix Requirements:

    Shall contain the word “corporation”, “incorporated”, “company”, “Societa per Azioni” or “limited”, or the abbreviation “corp.”, “inc.”, “co.”, “S.p.A.” or “ltd.”, or words or abbreviations of like import in another language. 
    GSC §33-655

  3. Appoint a Registered Agent

    Before you officially file to create your Connecticut LLC, you will need to decide who your Connecticut registered agent will be. A registered agent is a business's legal appointee to receive notice of lawsuit and other legal or government notices.

    State law requires every LLC to have a registered agent. The registered agent is designated when you file Connecticut articles of organization with the Connecticut Secretary of State - Commercial Recording Division.

    Our reliable registered agent service fulfills this requirement. You get:

    • Same-day documents from our local office in Glastonbury
    • Immediate online access to state forms with our address and, where required, our signature
    • Annual fees from $89 to $99 per state with no additional charges

  6. Establish Bylaws & Corporate Records

    Your corporation must keep correct and complete books and records.

    Draft bylaws (potentially using a template) which is the governing document for the corporation. The bylaws of a corporation may contain any provision for managing the business and regulating the affairs of the corporation that is not inconsistent with law or with the articles of incorporation (C.R.S. 7-102-106). You will review and ratify the bylaws at your first board of directors meeting.

    A corporation shall keep as permanent records minutes of all meetings of its shareholders and board of directors, a record of all actions taken by the shareholders or board of directors without a meeting, a record of all actions taken by a committee of the board of directors in place of the board of directors on behalf of the corporation, and a record of all waivers of notices of meetings of shareholders and of the board of directors or any committee of the board of directors (C.R.S. 7-116-101).

    Your filed articles of incorporation and bylaws are the first documents for your corporate records. Your corporation will generate many other official records such as:

    • Meeting minutes
    • Shareholder resolutions
    • EIN verification letter
    • Amendments and other filings made to the corporation over its lifetime

    Organizations need a secure, centralized tool for managing and accessing sensitive records. Our Records Manager software offers a simple, efficient way for corporations to store records, track officers, directors, and shareholders, and customize meeting notifications.

  7. Appoint Initial Directors

    The initial directors serve on the board until the annual meeting of shareholders (when directors are elected to the board). If the initial directors are not named in the articles of incorporation, they are appointed by the incorporator. The incorporator documents and signs this action for the corporate records.

  8. Hold Organizational Meeting

    Hold the organizational meeting of the incorporators or initial directors in compliance with GSC §33-639. Keep minutes of this meeting.

    The following state laws apply unless overridden by the organizational documents, where permissible.

    Directors Officers
    • Number: At least one is required.
    • Qualifications: None required.
    • Quorum: Majority of directors, unless bylaws state otherwise.
    • As stated in the bylaws. One person may hold multiple offices. One officer is required to be responsible for maintaining corporate records.
  9. Issue Stock Certificates

    The owners may be issued stock certificates to serve as proof of ownership in the corporation. Remember to hold the first annual meeting of the shareholders (the owners of the corporation) according to bylaws and keep minutes of this meeting.

    The following state laws apply unless overridden by the organizational documents, where permissible.

    Shareholders Annual Shareholder Meeting
    • Qualifications: N/A
    • Stock Certificate: Not required.
    • Voting Trusts Allowed: Yes.
    • Required: Yes, unless directors are elected by written consent.
    • Action by written consent: Allowed if enough shareholders consent to equal the number required to take action by vote.
  10. Get a Federal Employer Identification Number (EIN)

    Your corporation must obtain an EIN regardless of whether it will hire employees.

    Submit to: Internal Revenue Service
    http://www.irs.gov/
    Form: IRS Form SS-4

  11. Report Beneficial Ownership Information to FinCEN

    As of January 1, 2024, millions of entities in the US need to report beneficial ownership information (BOI) to the Financial Crimes Enforcement Network (FinCEN) as part of the Corporate Transparency Act (CTA). Non-exempt corporations formed before that date must submit BOI by December 31, 2024, while those formed after must submit it within 30 days of formation. Our BOI Reporting Service includes up to four initial, updated, and corrected reports per year, ensuring the data you report to FinCEN is kept up to date.

  12. Get Connecticut State Tax Identification Numbers/Accounts

  13. Consider Electing S-Corp Taxation

    By default, your corporation is taxed as a C-Corporation. Some corporations, especially smaller ones, benefit from electing S-Corp tax treatment:

    • C-Corps suffer from double taxation: the corporation pays taxes on profits then members pay taxes on their distributions. If profits exceed $250,000 per owner, you provide employee benefits, or you will re-invest most of your profit in the business, you may benefit from the low tax rates on retained earnings under C-Corp treatment.
    • S-Corp treatment avoids double-taxation. It is generally the best choice for small businesses. To accomplish this, file Form 2553: S-Corp Election with the IRS.
  14. Obtain Business Licenses & Permits

    To run your business legally, you must obtain applicable licenses and permits. The easiest way to navigate the wide range of federal, state, and local requirements is to search by your business type and locality using the Small Business Administration Business License & Permit look-up tool.


    Connecticut Business License

    Not required



    General Business License licensure is not required on the State level in Connecticut.

    Connecticut does not have a general business license at the state level, but local licenses are often required.

  15. Ongoing Filings to Maintain Your Corporation

    You must file federal and state tax returns.


    Annual Report

    Many states also require business entities to file an annual report to maintain good standing with the secretary of state.

    Agency:Connecticut Secretary of State - Commercial Recording Division
    Filing Method:

    Online

    Agency Fee:

    $150

    Due:

    Annually by the registration anniversary date. Reports may be filed 30 days prior to the due date.

    Law:

    Connecticut General Statutes § 33-953.

    Penalties:

    No fee. Not in good standing.

    Notes:
    • Anyone with authority may file.

    For more details, see our Connecticut annual report information center page.

    You will need to demonstrate your company’s good standing to banks, customers, and other state agencies. After all the work involved in forming your Connecticut corporation, don’t let a missed annual report filing cause your new business to fall out of compliance.

    Tracking and filing annual reports on your own can be time consuming and lead to accidental lapses. Protect your corporation’s good standing with Managed Annual Report Service, which tracks and automatically files reports on time, every time, so you can focus on your business.
