How to Register Your Business in Connecticut in 7 Simple Steps

If you’re starting a business in Connecticut, the process of registering your business can seem overwhelming. However, this guide breaks down the process into seven simple steps, making it a much easier task. 

By following these steps, entrepreneurs can ensure that their business is registered with the appropriate legal structure, allowing them to get their business up and running quickly.

Step 1: Choose Your Business Structure

One of the first decisions you’ll need to make when registering your business is choosing its legal structure. The structure you choose will determine your tax obligations, your personal liability, and your management requirements. 

Sole Proprietorship

A sole proprietorship is the simplest business structure in Connecticut. As the owner, you and your business are considered the same entity, and you’re personally responsible for the business’s debts and liabilities. This structure is easy to set up and has minimal legal and administrative requirements. In Connecticut, you don’t need to register your sole proprietorship with the state, but you may need to obtain local permits or licenses.

General Partnership

A general partnership is a business owned by two or more people who share in the profits and losses. Each partner is personally liable for the business’s debts and legal obligations. In Connecticut, you don’t need to register a general partnership with the state, but you may need to file a “Certificate of Trade Name” (DBA) with the Secretary of State.

Limited Partnership (LP)

In Connecticut, a limited partnership consists of one or more general partners who manage the business and have unlimited personal liability and one or more limited partners who provide capital but have limited liability. To create an LP in Connecticut, you must file a “Certificate of Limited Partnership” with the Secretary of State.

Limited Liability Company (LLC)

An LLC is a flexible business structure that combines the liability protection of a corporation with the tax benefits and simplicity of a partnership. In Connecticut, you need to file a “Certificate of Organization” with the Secretary of State and create an Operating Agreement to outline the company’s management and ownership structure.


A corporation is a legal entity separate from its owners (shareholders) that offers limited liability protection. There are two types of corporations in Connecticut: 

  • C-corporations
  • S-corporations

To create a corporation in Connecticut, you must file a “Certificate of Incorporation” with the Secretary of State, create bylaws, issue stock, and hold regular board and shareholder meetings.

Choosing the right business structure in Connecticut is crucial for the success of your business. Consider the level of personal liability protection you need, your tax obligations, and your management requirements when making this decision. Consult with a legal or business professional if you need assistance in making this choice.

Step 2: Select a Unique Business Name

When it comes to selecting a unique business name in Connecticut, it’s important to follow specific guidelines and regulations to avoid any legal issues. The name you choose must not be identical or too similar to any existing business entity in Connecticut. To check the availability of a business name, you can search the Connecticut Secretary of State’s website.

Connecticut has specific rules for naming your business, including restrictions on certain words and phrases. The name you choose must be distinguishable from other business names in Connecticut, and it should not be misleading or imply that your business is associated with a government agency.

Once you have found a unique name for your business, you should consider registering it as a trademark or service mark with the Connecticut Secretary of State’s office. This will provide you with exclusive rights to use that name in commerce in Connecticut.

It’s also important to note that if you’re planning to operate your business under a name other than your own, you’ll need to file a “Certificate of Trade Name” (DBA) with the Secretary of State’s office. This certificate allows you to use a trade name for your business that’s different from the legal name of your business entity.

By following the naming guidelines and regulations, you can successfully register your business name in Connecticut and protect your brand identity.

Step 3: Consider Taxes and Other Costs in Connecticut

Connecticut LLCs are taxed as pass-through entities, with members paying personal income tax on their share of the LLC’s profits. LLCs may also be required to pay sales tax and employer taxes, depending on their activities.

Here are some additional details about the taxes that LLCs in Connecticut may be subject to:

  • Income tax: LLCs in Connecticut are not subject to corporate income tax. However, the income of the LLC is passed through to the individual members, who are then taxed on their share of the income on their personal tax returns. The individual members’ tax rates will vary depending on their filing status and income level.
  • Sales tax: LLCs in Connecticut may be required to pay sales tax on the sale of goods or services. The sales tax rate in Connecticut is 6.35%. However, there are a number of exemptions from sales tax, including sales of food, clothing, and prescription drugs.
  • Employer taxes: Employers with employees in Connecticut are required to withhold federal and state income taxes from their employee’s paychecks. Employers are also required to pay payroll taxes, which include Social Security, Medicare, and unemployment taxes. The rates for these taxes vary depending on the employee’s income and the number of employees that the employer has.

If you’re forming an LLC in Connecticut, it’s important to understand the tax implications of doing so. You should consult with a tax advisor to determine how your LLC will be taxed and to ensure that you’re in compliance with all applicable tax laws.

Business owners in Connecticut can simplify their registration process by utilizing online services such as ZenBusiness and Swyft Filings. These platforms provide a variety of packages, which encompass aid with submitting the required documentation to the Secretary of State, acquiring an Employer Identification Number (EIN), and drafting an operating agreement. Furthermore, these services offer continuous compliance assistance to ensure businesses maintain their good standing with the state.

Step 4: Register and Acquire Licenses and Permits in Connecticut

To operate your business in Connecticut, it’s important to obtain the necessary licenses and permits. Here are the key requirements:

Tax Registration: If you plan to sell goods in Connecticut, you need to register with the Department of Revenue Services (DRS) to collect sales tax. If your business has employees, you must also register for employer withholding taxes. You can do this online through the Connecticut Taxpayer Service Center (TSC) or by submitting Form REG-1, the Business Taxes Registration Application.

EIN (Employer Identification Number): If your business has employees or is taxed separately, you must obtain a federal EIN from the IRS. Even if it’s not required, getting an EIN can be beneficial for banking purposes and payment processing with other companies. You can apply for an EIN online without any filing fee.

Trade Licenses and Permits: These licenses and permits are required for various sectors, including accommodation and food services, agriculture, construction, retail and wholesale trade, environmental compliance, and health and safety. To find more information, consult the Department of Consumer Protection. Additionally, check the websites of the cities or counties where you will conduct business for any local license or permit requirements.

Professional and Occupational Licenses: These business licenses are necessary for individuals working in specific fields. For detailed information, contact the Occupational & Professional Licensing Division of the Department of Consumer Protection.

Step 5: Open a Bank Account For Your Business in Connecticut

Once you have registered your business and obtained all necessary licenses and permits in Connecticut, it’s important to open a separate bank account for your business. This will help keep your finances separate from your business finances and make it easier to track income and expenses for tax purposes.

When choosing a bank, consider factors such as fees, interest rates, and account features that are important for your business. You may also want to consider opening a business credit card to help build credit and manage expenses.

To open a business bank account in Connecticut, you’ll typically need to provide the following documents:

  • Your business registration paperwork
  • Your Employer Identification Number (EIN)
  • Your business license or permits
  • Your identification (driver’s license or passport)
  • Business financial statements (if applicable)

It’s important to shop around and compare options before choosing a bank to ensure you find the best fit for your business’s needs.

Step 6: Protect Your Intellectual Property in Connecticut

When starting a business in Connecticut, it’s crucial to protect your valuable intellectual property (IP) to maintain a competitive edge and safeguard your brand, products, and creations. Depending on the type of company you’re establishing, you may have various forms of IP that require protection.

File a Trademark with bizee


A trademark is a recognizable symbol, phrase, word, or design that distinguishes your products or services from others in the market. Registering a trademark provides legal protection and prevents unauthorized use of your brand identity.

To protect your trademark in Connecticut, you need to file an application with the United States Patent and Trademark Office (USPTO). The registration process typically takes several months to complete. Once your trademark is registered, it is protected nationwide, and you can take legal action against anyone who infringes upon it.

In Connecticut, original works of authorship, including literary, dramatic, musical, artistic, and other intellectual creations, are protected by copyright law. This protection extends to written content, software, web content, films, sound recordings, images, and other creative expressions.

As the creator of a work in Connecticut, you automatically have copyright protection. However, registering your copyright with the U.S. Copyright Office provides additional legal benefits and evidence of ownership. Registering your copyright in Connecticut allows you to enforce your rights in court if infringement occurs and provides greater protection for your work.


If you invent a new product or process in Connecticut, obtaining a patent is crucial to secure exclusive rights over your invention. A patent grants you the authority to prevent others from making, selling, or importing your patented item for a specified period.

The patent application process can be lengthy and complex, often taking several years to complete. To protect your invention, you must file a patent application with the United States Patent and Trademark Office (USPTO). Starting the patent application process early is essential to safeguard your invention and prevent others from capitalizing on your unique creation.

By taking the necessary steps to protect your intellectual property in Connecticut, you can establish a solid foundation for your business, maintain your brand’s integrity, and ensure that your innovative ideas and creations remain secure.

Step 7: Set Up Your Payment Infrastructure in Connecticut

Once your business is registered and ready to operate in Connecticut, it’s important to set up your payment infrastructure. This includes selecting payment methods, setting up merchant accounts, and establishing a billing and invoicing system.

To set up your payment infrastructure in Connecticut, consider the following steps:

  1. Determine which payment methods you want to accept, such as credit cards, debit cards, or mobile payments
  1. If you plan to accept credit or debit card payments, you’ll need to set up a merchant account with a payment processor or bank
  1. Choose a billing and invoicing system that suits your business needs. This may include invoicing software or a payment gateway
  1. Be sure to comply with state and federal regulations related to payment processing, including those related to data security and privacy
  1. Test your payment system to ensure it’s working correctly and efficiently

By setting up your payment infrastructure, you can provide a convenient and secure payment experience for your customers and streamline your business operations in Connecticut.
