Owners can get liability protection as the corporation is a separate entity, and only the latter's assets can be used in case of debts and obligations. Opening your own corporation in Connecticut also comes with lucrative tax benefits.

What Are The Requirements For Opening A Corporation In Connecticut? 

Starting your own corporation in Connecticut is relatively easy. However, entrepreneurs or business enthusiasts must complete these steps carefully to start their own company. 

Create A Corporate Name 

The first step to starting your corporation in Connecticut is creating a name. The name should be unique in nature. People should be able to set this name apart from names of other businesses registered with the Secretary of State. 

One can visit the Connecticut Secretary of State business registry search to check what names are available. 

Individuals can reserve a business name for 120 days by filing an Application for Reservation of Name. This application must be filed with the Secretary of State and the fee is $60. 

Connecticut law requires businesses to have one of the following designations: corporation, incorporated, company, Societa per Azioni, or limited; or the abbreviation corp., inc., co., S.p.A., or ltd.

File Certificate Of Incorporation

A corporation gets legal status when the owner files the certificate of incorporation with the Secretary of State in Connecticut. The certificate must include the following details: 

  • Name of corporation 
  • Number and class of shares the corporation can issue if the corporation will have more than one class of shares
  • The rights and limitations associated with each share class 
  • NAICS code
  • The name, address, and signature of an agent for service of process
  • The name, address, and signature of each incorporator, and 
  •  If the corporation opts to benefit from corporation status 

The certificate of incorporation can be filed online or via mail. The fee for filing the same is $250. This also includes a minimum franchise tax worth $150. 

Equip Your Corporation With A Registered Agent 

Every Connecticut corporation shall have a registered agent for service of process in the State. A registered agent refers to a person or a corporation that agrees to accept the legal papers of the corporation if they are sued. The agent shall have agreed to the same before the corporation names the agent. 

Here are some requirements for a registered agent. The Connecticut business agent can be:

  • The agent shall be a full-time resident of Connecticut. This agent can include an officer, director, or corporation shareholder. 
  • A Connecticut business entity
  • A foreign business entity that has been equipped with a certificate of authority to carry out business transactions in Connecticut

 It is also crucial for the agent to have a physical address in Connecticut. Generally, small corporations opt for a director or officer to serve as an agent initially. You can always name a different agent later. 

Prepare A Stock Structure

The certification of incorporation filed with the Secretary of State must also state the total number of shares a corporation is authorized to issue. Stocks of a corporation can be divided into various classes or series. For example, certain sorts of stocks can offer voting rights in the company while other sorts of stocks may not. 

In case of more than one class or series of shares, the certificate shall include the number of shares in each class or series. The certificate shall also provide a designation for each class or series. Before shares are issued, the certificate shall also state the terms, including that class or series's preferences, rights, and limitations. 

Prepare A Set Of Corporate Bylaws

For the uninitiated, corporate bylaws refer to an internal corporate document. This document sets the rules for operating your own corporation. These bylaws are not filed with the state. There is no legal requisite for a corporation to be equipped with corporate bylaws. 

However, it is crucial to adopt the same as they establish the corporation rules of your new endeavor. They can help showcase the legitimacy of your corporation to banks, creditors, and the IRS. 

As a corporation owner, you must keep track of bylaws, articles, stock certificates, minutes of shareholders, director meetings, and other vital documents. A Corporate records book can help. 

Choose Initial Directors And Hold Your First Ever Board Meeting

The onus is on the incorporator or the person who signed the articles to appoint the corporate directors for the board. The appointed directors will continue to serve on the board until the first annual meeting of shareholders takes place. During the annual meeting, the shareholders appoint the next set of board members as directors. 

The incorporator must complete and sign an "Incorporator's statement" consisting of the names and addresses of initial directors. There is no need to file this statement with the Secretary of State. However, the incorporator must maintain a record of it in the corporate records book. 

Once initial directors have been appointed, the first board meeting can occur. During this meeting, the directors appoint corporate officers, adopt bylaws, choose a corporate bank, set the fiscal year, greenlight the issuance of shares of stock, and adopt an official stock certificate form and corporate seal. It is pertinent to remember that share issuances by small privately held corporations are exempted from Federal and State Security Laws. 

File An Annual Report

Any individual or people authorized to carry out business-related activities must file an annual report with the Connecticut Secretary of State. It is required for domestic corporations to file this annual report online within 30 days following the organizational meeting of the corporation. 

The report is filed with the help of the Organization and First Report form. It shall include the corporation's name, the principal office, names, and addresses of directors and officers. All annual reports must be filed online via the Connecticut Secretary of the State Online Filing System

For domestic corporations, the filing fee is $150. For foreign corporations, the filing fee is $435. 

Obtain An Employee Identification Number 

The corporation must also equip itself with an Employee Identification Number or EIN. You can obtain your EIN by completing an application on the IRS website. There is no filing fee required.

How To Register A Foreign Corporation In Connecticut?

All corporations outside Connecticut shall register with the Connecticut Secretary of State. It is also required for foreign corporations to appoint a registered agent for service of process. The agent must have a physical location or address in Connecticut. 

The foreign corporation must also file an Application for a Certificate of Authority to complete its registration. There shall also be an authenticated certificate regarding the corporation's legal existence from its home state, which should be at least 90 days old.

The certificate of authority application can be filed online or via postal mail. The filing fee for the same is $385. Before filing, the foreign corporation must check whether the business name is available. To do so, they can check with the Connecticut Secretary of State's business registry search.

The business must file a resolution by its board of directors that has been certified by its secretary. In this resolution, they will adopt the fictitious name and the Application for a certificate of authority.
