First, you need to gather basic information about your LLC, including the names and addresses of the managers or members. The LLC members are typically the people who own and run the business. They are also the ones who can take profits out of the business to pay themselves.

You will need a distinctive and original name for your Connecticut LLC that’s not used by any other business in CT. To find out if another company is using your chosen business name, carry out a Connecticut business entity name search on the CT Secretary of State website.

There are a few rules you’ll need to follow when choosing an LLC name. You can find out more in our guide to searching for and naming your Connecticut LLC.

Every Connecticut LLC must have a designated street address. That could be your home address (if you’re running the company from your residence), your company’s office building or any physical address of your preference. The address can be outside the state of Connecticut, but it cannot be a P.O. Box.

Every CT LLC or corporation must have a “Registered Agent.” This is an official position; the Registered Agent is someone who receives official legal and tax correspondence and has responsibility for filing reports with the Connecticut Secretary of State.

This position can be filled by you, another manager in the business or a dedicated Registered Agent service. Your CT Registered Agent must have a physical street address in Connecticut and must be present to receive important documents for your company during business hours.

At Incfile, all of our packages include a Connecticut Registered Agent service that is free for the first year and just $119 per year afterward. We also have a dashboard where you can log in and easily view any document your Registered Agent has received on your behalf.

You will need an EIN to identify your business to the IRS. You use this number when filing and paying taxes or when submitting payroll information and payments for your employees. You can obtain one directly from the IRS, or we can get one for you as part of the Connecticut LLC business formation process.

Once you've gathered all the information for your Connecticut LLC, you’ll need to file a formal document with the CT Secretary of State. Known in some states as “Articles of Organization,” in CT, this document is called your “Certificate of Organization,” and filing the document creates your Connecticut LLC. Here’s what is typically included:

• Your business name and various addresses

• Details of your Registered Agent

• Names of managers or members of the LLC at the time of filing

• Addresses of managers or members of the LLC at the time of filing

• Name of the incorporator

You can file your Connecticut LLC Certificate of Organization online, mail in a form or have Incfile do it on your behalf. There is a fee to file and start an LLC in Connecticut. You only need to file your Certificate of Organization once.

Some states, including Connecticut, allow certain occupations to form “Professional LLCs.” These types of businesses typically have special requirements and licensing. Here are the occupations that the CT Secretary of State allows to form Connecticut professional LLCs: Dentists, naturopaths, chiropractors, physicians and surgeons, physician assistants, doctors of dentistry, physical therapists, occupational therapists, podiatrists, optometrists, nurses, nurse-midwives, veterinarians, pharmacists, architects, professional engineers (or jointly with architects and professional engineers), landscape architects, real estate brokers, insurance producers, certified public accountants and public accountants, land surveyors, psychologists, attorneys-at-law, licensed marital and family therapists, licensed professional counselors, licensed or certified alcohol and drug counselors and licensed clinical social workers.

If your business is already operating in another state and expanding to Connecticut, you’ll need to form a foreign LLC.
