You can go through this process on your own, or you can hire a service like Firstep to complete this process for you. In Connecticut, LLCs are one of the most popular business structures as they are relatively simple to form, offer owners liability protection, and are flexible in their ownership structures.

Step 1: Choose a Business Name

The first step to forming a new LLC will be to choose a business name for your LLC. The name you choose will need to be unique and distinguishable enough from other active businesses in the state. It is helpful to use the business name search tool to identify what names are already taken and in use by active businesses. In Connecticut, business names are not placed on hold for any reason so if a business is no longer active then the name will be available. This tool can be useful to have while brainstorming potential names so you are not choosing names that are already taken.

Your business name will need to include certain designators in it such as "LLC", "L.L.C.", or "Limited Liability Company". Also, you will be required to avoid using certain terms in your name that can be misleading in your business name. These terms are things like "bank", "insurance", "law", or other professional services that signal your business is operating in a specialized industry if you are not a part of those.

Step 2: Appoint a Registered Agent

Any LLC that is formed in Connecticut will need to have an active registered agent appointed to the business. A registered agent will be responsible for receiving any service of process being sent to your business, including important notices from the state as well as notice of any lawsuits against your business. You are able to appoint whoever you would like as your registered agent such as yourself, a trusted friend or family member, or you can hire a registered agent service to handle this for your business. A service is useful as they are able to meet all requirements of a registered agent in your state, as well as handling receiving these documents and getting them to you in a timely manner.

In Connecticut, your registered agent will be required to be at least 18 years old, have an active address in the state, and be available during regular business hours which are Monday through Friday 9am-5pm. Be aware that if you choose to be your own registered agent, you will need to to list your personal address on your formation documents which are public information. To avoid this, using a registered agent service or a friend or family member allows you to list their current address instead and give you added levels of privacy.

Step 3: Submit Your Certificate of Organization

With your business name and registered agent chosen for your LLC, it's time to go through the process of submitting your certificate of organization to officially create your new LLC in Connecticut. This will be done through the business website and you are able to do this on your own or hire a service like Firstep to take care of this for you. You will find the form after going to the start your business tab and choosing to register your business. From here, you will choose register today and select the LLC structure when prompted.

This form, called the Certificate of Organization, will be the founding document for your new LLC. After choosing your business structure, you will submit your business name and choose a designator to be attached to your LLC. Then, you will need to provide an email address to be assigned to your business as well for any notices the state will need to send to you. The next step will be to select an NAICS code, which is what describes your core business operations. There is a search bar to look up what type of business you run to make this easier, or you can browse through the different descriptions to find one that fits your business the best. After choosing your NAICS code, you will have a business category survey to get a better understanding of your business, but you can choose not to answer if you would not like to disclose this information.

The last section will be your main business information. First, you will be required to submit your business's physical address and mailing address information. Also, you need to enter your registered agent information including the physical address and mailing address as well as the Connecticut residence address your registered agent will list to ensure they are in the state. With this information entered, you will then need to submit your principal or member information. This just requires a first and last name, title, and email address for each member. Lastly, you will be taken to a review page to ensure all information you have entered is correct. Then you are required to provide information on the organizer of the business, and finally be taken to the payment page. The total amount for forming an LLC in Connecticut is $120, and the processing time is typically around 3 to 5 business days.

Step 4: Draft an Operating Agreement

With your LLC formed in Connecticut, a good next step is to draft an operating agreement. An operating agreement will detail the roles and responsibilities of the owners of the LLC. Along with that, this will outline the ownership percentages, voting rights, and processes for decision making. It can be very helpful to have these things in writing to avoid any disputes within your ownership and in choosing how to decide what to do with your LLC, as well as ensuring your business is operating legally and following all guidelines when doing business.

An operating agreement is not legally required for Connecticut LLCs, but it is highly recommended for business owners due to how they help outline certain processes and regulations for your business. As your business grows, operating agreements are useful to standardize the processes of members joining and leaving the business, and how you will handle voting and disputes between members.

Step 5: Obtain an EIN (Employer Identification Number) for your LLC

Now that you have formed your LLC and drafted an operating agreement, one of your last steps will be to obtain an EIN for your business. Your EIN will be issued to you by the IRS, and you will only be able to get one number for each business. Once you get one, you will not be required to renew it ever. An EIN is important as this will be used for many reasons such as tax purposes, hiring employees, and opening a business bank account.

When you are applying for various business licenses or similar registrations, you might be required to present your EIN documentation to prove your business is legitimate and legally operating. You are able to either obtain your EIN on your own, or you can have a service like Firstep get this number for you. Even if you have gotten an EIN before and lost the paperwork or number associated with it, you can still retrieve this number from the IRS. However, this can be a lengthy process so it's important to begin this process before your EIN will be required for anything such as tax season, hiring employees, or opening a bank account.

Step 6: Maintain Ongoing Compliance

With your LLC officially formed and all required documents obtained, your next step will be to maintain good standing for your business. This is extremely important for new business owners, and will ensure your business is able to continue operating legally within the state. The good standing of your business will mainly rely on submitting your annual reports on time, as well as registering for any required business licenses that relate to your business industry.
