Registering Your Connecticut Business

Beyond professional licensing, Connecticut requires most businesses to register an entity (LLC, Corporation, or Sole Proprietorship) with the Secretary of State. The standard LLC filing fee is $120.

Operating from home typically requires a Home Occupation Permit issued by your local city or county zoning department. This ensures your business activity won't disrupt the residential character of your neighborhood.

Tax Registration: Personal services are subject to 6.35% sales tax in Connecticut. You must register with the Dept. of Revenue.
