Forming an LLC in Connecticut is a popular choice for entrepreneurs seeking liability protection and operational flexibility. The primary step involves filing a Certificate of Organization with the Connecticut Secretary of the State. This document formally creates your LLC as a distinct legal entity. The filing fee for the Certificate of Organization is currently $60. Before filing, you must choose a unique name for your LLC. The name must contain words like "Limited Liability Company," "LLC,"

Registering a 'Doing Business As' (DBA) in Connecticut

A "Doing Business As" (DBA) name, also known as a trade name or fictitious name, allows a business to operate under a name different from its legal name. For sole proprietors and general partnerships in Connecticut, registering a DBA is a requirement if they wish to use a business name other than their own personal name(s). This registration is handled at the town or city level, not with the state Secretary of the Office. If you operate as an LLC or Corporation in Connecticut and wish to use a

Also known as a Federal Tax Identification Number, an EIN is essential for businesses that plan to hire employees, operate as a corporation or partnership, or file certain tax returns. It's like a Social Security number for your business. Applying for an EIN is free and can be done directly on the IRS website. The application process is

For LLCs and Corporations, the Connecticut Secretary of the State requires the filing of a Biennial Report (for LLCs) or an Annual Report (for Corporations) every two years or annually, respectively. These reports ensure that the state has up-to-date information about your business, including its registered agent and principal of

Frequently Asked Questions

What is the main difference between an LLC and a Corporation in Connecticut?: An LLC in Connecticut offers pass-through taxation and simpler administration with limited liability. A Corporation (C-Corp or S-Corp) is a separate legal entity with more formal requirements, offering limited liability but potentially facing double taxation (C-Corp) or requiring specific IRS elections for pass-through taxation (S-Corp).

Do I need a separate business license in Connecticut?: While state business registration forms the legal entity, specific industries or professions may require additional licenses or permits from state agencies (e.g., healthcare, construction) or local municipalities. Check with relevant state departments and your local town hall.
