Starting an LLC in Connecticut is a relatively simple process that can offer your business some significant benefits. This article will walk you through the steps necessary to form an LLC in Connecticut.

We will also discuss some of the critical advantages of doing so. If you're thinking about starting a business in this state, a Connecticut limited liability company should be at the top of your list.

What is a Connecticut LLC?

A Connecticut LLC is a limited liability company formed under Connecticut law. It is a business entity that provides personal liability protection to its owners (called members).

This business structure is popular because it is relatively easy to set up and offers a lot of flexibility.

An LLC represents a separate legal entity from LLC owners and, as such, is responsible for its business debts and obligations.

This separates the personal assets of the Connecticut LLC members from the business assets and liabilities.

A limited liability company is a legal entity that allows business owners to protect their assets in the event of a lawsuit or other legal action.

This business structure is also popular because it offers tax flexibility. A company may also be helpful when it comes to tax planning since profits and losses can be passed through to shareholders and taxed on their individual returns.

LLCs can be taxed as a single proprietorship, partnership, or corporation, depending on how members structure their company.

The membership and management structure of a Connecticut LLC is also very flexible. There is no minimum or a maximum number of members, and the members can manage the company themselves or appoint managers to do so.

In order to conduct business under this structure, a business owner has to take a few steps that will have the LLC legally recognized as a business entity.

Step 1: Choose a Name for Your Business

A Connecticut LLC must have a unique business name that is not already in use by another business entity in the state. The name must also comply with Connecticut's naming guidelines.

The naming guidelines are relatively simple. The name must be different from the names of other business entities, and it cannot contain certain prohibited words such as "bank," "insurance," or "trust."

There has to be an abbreviation that includes the words "limited liability company" or the abbreviation "LLC".

Terms you can never include in a Connecticut LLC name include terms associated with a government agency, such as "Internal Revenue Service" or "Federal Bureau of Investigation."

When you're choosing a name, it's essential to make sure that the domain is available as well.

You can use a domain search tool to check availability.

You can perform a business entity search to make sure that your desired name is not already in use. You can also check the Connecticut Secretary of State's business name database.

If your business name is available, you can apply to reserve a business name with the Connecticut Secretary of State. Your limited liability company name will be reserved for the next 120 days by completing this process.

There is a $60 filing fee for filing an Application for a Reservation of Name.

Step 2: File Certificate of Organization With the Secretary of State

Once you have determined that a limited liability company is the right business structure for you and your desired name available, it's time to file your Connecticut LLC Certificate of Organization with the Secretary of State.

This document officially creates your LLC and includes information such as its name, registered agent, and principal place of business.

A filing fee of $120 can be paid online with a credit card or check. For additional details on the cost of forming an LLC in Connecticut, see our guide.

The certificate can be filed online or by mail to the Business Service Division, Connecticut Secretary of the State.

Step 3: Appoint a Connecticut Registered Agent

Agent service is an organization that is appointed by the LLC to receive service of process on its behalf. This means that if your LLC gets sued, the registered agent will be notified and will be responsible for forwarding any legal documents to you, such as the operating agreement.

There are a few things to keep in mind when appointing a registered agent:

  • The registered agent must be a resident of Connecticut or a business authorized to do business in the state.
  • The registered agent must have a street address in Connecticut where they can receive mail and legal documents.
  • The registered agent should have a reputation for professionalism and be responsive to inquiries.

If you choose to use a registered agent service in Connecticut, be sure to do your research and compare prices before selecting one. You can find a list of registered agent services on the Connecticut Secretary of State's website.

Step 4: Draft and File an LLC Operating Agreement

Operating agreements are internal LLC documents that govern the company's operations.

An operating agreement includes things like members' percentage interests, voting rights, and management procedures.

Although not required in Connecticut, it's a good idea to have an operating agreement in place. With an operating agreement, the LLC can avoid any disputes among members down the road.

Connecticut LLC operating agreements must include the following:

  • Name of the LLC and its principal place of business
  • The purpose of the LLC
  • The names and addresses of all members, managers, and officers
  • How profits and losses will be allocated among members
  • Procedures for amending the agreement or dissolving the company

You can find a template for a Connecticut LLC operating agreement online or through an attorney. Be sure to customize it to fit your company's specific needs.

Step 5: Get a Tax ID Number (EIN)

Federal tax identification number (employer identification number or federal employer identification number) is used by the Internal revenue Service to identify taxpayers.

You will need an EIN in order to get started, so be sure to apply for one as soon as you finish with your operating agreement. You can apply for a tax ID number online at the IRS website.

Your EIN will be mailed to you, and it will also be included in your LLC formation documents.

Once you have your EIN, you can open a bank account for your LLC and hire employees. This will make it easier to track your business expenses and income, making filing taxes much simpler.

Step 6: Register With the Connecticut Department of Revenue Services

The Connecticut Department of Revenue Services handles the taxation of businesses in Connecticut.

Once you have formed your Connecticut LLC, you will need to register and file an annual tax return.

The amount of taxes you owe will depend on your LLC's income and deductions. Be sure to speak with an accountant or tax specialist to understand your business's specific tax obligations better.

Step 7: Open a Business Bank Account

Connecticut LLCs offer personal asset protection. However, if you don't keep your business and personal assets separate, you risk piercing the corporate veil.

For this reason, it is essential that you open an LLC bank account that will not be used for any personal expenses. This will help to clearly delineate your business and personal finances and make it easier to track your company's financial progress.

To open an LLC bank account:

  • Contact the bank of your choice and schedule an appointment with a business banker.
  • Bring your operating agreement and the Certificate of Formation
  • Complete the necessary paperwork and provide your company's EIN
  • Set up a system for tracking expenses and profits.

There are many banks that offer business checking accounts specifically for LLCs. Be sure to research the best option for you and compare interest rates, fees, and other features.

You may also want to consider a credit union, which often offers lower rates and fees than traditional banks.

Step 8: Get Necessary Licenses and Permits

Business licenses and permits are necessary in order to operate your business. The types of licenses and permits you need will vary depending on the type of business you are starting.

In Connecticut, you can find a list of all required licenses and permits on the Department of Consumer Protection's website.

The Department of Consumer Protection offers a number of resources to help business owners understand and comply with licensing requirements, including an overview of the licensing process, frequently asked questions, and contact information for each bureau within the department.

You can also contact the local town hall or economic development office for assistance.

Some common licenses and permits for businesses in Connecticut include:

  • General business license
  • Tax registration certificate
  • Seller's Permit
  • Foodservice permit
  • Contractor license
  • Home improvement contractor license.

A professional limited liability company in Connecticut will likely need more business licenses than a traditional LLC because it will provide professional service.

For example, a professional LLC might need a business license to practice law, medicine, or accounting.

Connecticut LLC tax requirements

When you start an LLC in Connecticut, the tax structure of your business will determine how you report taxes.

An LLC is treated as a sole proprietorship for tax purposes, provided that it only has one member. On the other hand, LLCs with more than two or more members are taxed like partnerships.

Both entities can still choose corporate taxation (either S corporation or C corporation) if they meet the requirements.

LLCs in Connecticut have to collect sales tax if they are selling products or services in the state.

The tax rate is currently at six and a half percent, but it might change in the future. Income tax is also collected on LLCs, and it's computed similarly to how partnership income tax works.

Connecticut business entity tax is a tax on the privilege of doing business in the state.

The tax is imposed on all LLCs but varies depending on the LLC's income. The tax ranges from $250 to $25,000, depending on how much money the LLC makes.

There are also a number of local taxes that businesses in Connecticut have to pay.

These vary by municipality, so it's important to check with your town or city hall for more information. Generally, these taxes include property tax, income tax, and sales tax.

If your limited liability company has employees, you'll need to pay employer taxes, unemployment insurance, workers' compensation, and disability insurance.

The amount that you'll have to pay for these depends on the number of employees and the type of coverage you choose.

As a business owner in Connecticut, it's important to stay up-to-date on all the latest tax laws. Make sure to consult a tax professional for legal or tax advice.

You must have a physical address in Connecticut where notices and other official documents can be delivered, and you must be available during normal business hours to accept service of process on behalf of the LLC.

Does Connecticut Have a Franchise Tax?

Yes, but only if your LLC is a corporation. If your LLC is a partnership or sole proprietorship, you don't have to worry about the franchise tax.
