Connecticut Corporation Requirements

After forming a corporation, you must undertake certain steps on an ongoing basis to keep your business in compliance. These steps are also important in preserving the limited liability a corporation provides its owners. This guide outlines the ongoing requirements for Connecticut corporations.

Corporate records

Connecticut corporations must keep the following items with their corporate records at the principal place of business:

  • The Certificate of Incorporation and bylaws and all amendments to both
  • Minutes from all meetings of directors and shareholders
  • A record of actions taken by shareholder or directors without a meeting
  • A record of all actions taken by a committee of the board of directors in place of the full board of directors
  • Resolutions adopted by the directors creating one or more classes or series of shares and fixing their relative rights, preferences and limitations
  • A record of shareholders, including their names and addresses, listed alphabetically by class of stock
  • All written communications to shareholders within the past three years, including financial statements
  • A list of the names and business addresses of current directors and officers
  • The corporation’s most recent annual report

Corporate taxes and fees

The following are taxation requirements and ongoing fees in Connecticut:

  • Annual report and franchise tax. Connecticut requires corporations to file an annual report on or before the last day of the incorporation anniversary month. The fee for the annual report is $150. Connecticut also has a corporation franchise tax that is due at the time of incorporation and when a corporation’s authorized shares are increased via amendment, merger, etc. The franchise tax fee is calculated on the number of authorized shares, and there is a minimum fee of $150.
  • Taxes. For complete details on state taxes for Connecticut corporations, visit Business Owner's Toolkit or the State of Connecticut.
  • Federal tax identification number (EIN). An EIN is required for corporations that will have employees. Additionally, most banks require an EIN in order to open a business bank account.
  • State tax identification number. Connecticut does not require a state tax identification number.
