How To Make A LLC In Connecticut: Complete 2026 Formation Guide
Setting up a Limited Liability Company (LLC) in Connecticut provides business owners with essential personal liability protection, tax flexibility, and operational simplicity. This guide outlines the exact statutory steps, filing fees, and compliance requirements mandated by the Connecticut Secretary of the State (SOTS) for 2026.
Understanding the Connecticut LLC Landscape in 2026
Forming a business entity requires a clear understanding of state-level statutes, portal mechanics, and regulatory obligations. Connecticut business filings are handled digitally through the CONCORD system, managed by the Office of the Secretary of the State.
Why Choose a Connecticut LLC?
- Asset Protection: Members' personal assets are generally shielded from business debts, civil litigation, and commercial liabilities.
- Tax Flexibility: LLCs can elect to be taxed as a sole proprietorship, partnership, S-corporation, or C-corporation depending on revenue streams and financial goals.
- Streamlined Management: Management structures can be member-managed or manager-managed, offering operational freedom without heavy corporate formalities.
Pre-Formation Checklist and Name Availability Rules
Before submitting paperwork to the state, foundational decisions must be made regarding the naming convention, registered agent, and internal structure of the business.
Selecting a Compliant Business Name
Connecticut state law requires your LLC name to be distinguishable from any other active business entity registered within the state.
- The name must include an acceptable designator, such as "Limited Liability Company," "L.L.C.," or "LLC."
- Words that imply a specific regulated industry (such as bank, insurance, or university) require specialized licensing or approval from state regulatory boards.
- You can check real-time name availability using the CONCORD business search portal on the Connecticut Secretary of the State website.
Appointing a Registered Agent
Every Connecticut LLC must maintain a registered agent with a physical street address within the state (P.O. boxes are strictly prohibited). The registered agent is legally responsible for accepting service of process, state correspondence, and legal notices. The agent can be:
- An individual resident of Connecticut who is at least 18 years old.
- A domestic or foreign corporation, LLC, or statutory trust authorized to transact business in Connecticut.

Step-by-Step Instructions to Form Your Connecticut LLC
Executing the formation process accurately prevents costly processing delays. Follow these operational steps to establish your entity.
1. File the Certificate of Organization
The official document that legally creates your LLC is the Certificate of Organization.
- Filing Method: File online through the Connecticut CONCORD portal for expedited processing.
- Filing Fee: The standard state filing fee is $120.
- Required Information: You must provide the LLC name, principal office address, mailing address, registered agent name and physical address, details on management structure (member-managed or manager-managed), and the electronic signature of the organizer.
2. Draft an Operating Agreement
Although Connecticut law does not strictly require you to file an Operating Agreement with the state, drafting one is critical for internal governance. This document outlines member ownership percentages, profit and loss distribution, voting rights, management duties, and procedures for adding or removing members. It prevents internal disputes and reinforces your corporate veil.
3. Obtain an Employer Identification Number (EIN)
An EIN is a federal Tax ID issued by the IRS, essentially acting as a Social Security number for your business.
- You need an EIN to open a business bank account, hire employees, and file federal taxes.
- Applications can be completed online via the IRS website for immediate issuance at no cost.
4. Register with the Connecticut Department of Revenue Services (DRS)
Every LLC operating in Connecticut must register with the Department of Revenue Services to handle state tax obligations.
- Business Entity Tax (BET): Note that Connecticut repealed the annual $250 Entity Tax, but LLCs must still register for state sales tax, withholding tax, or room occupancy tax depending on their business model.
- Registration is handled online through the DRS Taxpayer Service Center (TSC) portal.

Frequently Asked Questions
How long does it take to form an LLC in Connecticut?

Do I need a physical office in Connecticut to form an LLC?

What is the annual cost of keeping an LLC active in Connecticut?
The primary ongoing state fee is the $80 Annual Report fee due every year during your anniversary month. There are no other recurring state franchise taxes for standard LLCs.
