Overview

Connecticut does not issue a general state business license. Businesses selling taxable goods or services must register for a Sales and Use Tax Permit with the Connecticut Department of Revenue Services (DRS).

Individual Connecticut towns and cities may require their own local business licenses or registrations. Requirements vary by municipality.
