Connecticut State Registrations Required Before Opening a Business

Starting a business in Connecticut involves several key state registrations to ensure compliance and smooth operations. Completing these registrations early helps avoid delays and penalties.

1. Business Entity Registration

Register your business entity with the Connecticut Secretary of the State. This includes corporations, LLCs, partnerships, and limited partnerships.

• File the appropriate formation documents (e.g., Articles of Incorporation or Organization).
• Obtain a Certificate of Incorporation or Organization as proof of registration.

2. Register for State Taxes

Register with the Connecticut Department of Revenue Services (DRS) to handle state tax obligations.

• Obtain a Sales and Use Tax Permit if selling taxable goods or services.
• Register for employer withholding tax if you plan to hire employees.
• Consider registration for other applicable taxes such as corporate business tax or excise taxes.

3. Employer Requirements

If hiring employees, register with the Connecticut Department of Labor for unemployment insurance and workers' compensation.

• Set up payroll systems to comply with state withholding and reporting.
• Maintain employee records and proper classification to comply with labor laws.

4. Additional Licenses and Permits

Depending on your business type and location, you may need additional state or local licenses.

• Check the Connecticut Business One Stop portal for industry-specific licensing requirements.
• Obtain health permits, professional licenses, or environmental permits as applicable.

5. Register a Trade Name (If Applicable)

If operating under a name different from your legal business name, file a trade name (DBA) registration with the Connecticut Secretary of the State.

As of 2026, keeping all registrations current and maintaining proper recordkeeping will support ongoing compliance and operational efficiency in Connecticut.
