Occupational License

A variety of occupations and professions in the state are regulated and need to be registered before offering certain services. A few common professions that require licensing in Connecticut include; acupuncturists, athletic trainers, family planners, landscape architects, pharmacists, and many more. Additional information, fees, and licensing requirements for professions are available from the State of Connecticut.

In addition to professional licensing, there are a few other types of businesses that need licensing that are not covered by the State, a few of which include:

Employer Identification Number (EIN)

Many businesses will register with the Internal Revenue Service (IRS) for an EIN (or FEIN, Federal Employer Identification Number, or Federal Tax ID Number). The EIN is the business equivalent for a Social Security Number for an individual. CorporationsLimited Liability CompaniesPartnerships, and Sole Proprietorships with employees will all need to register for one. Sole Proprietorships without employees can use the owner’s Social Security Number.

There is no cost for an EIN, and it only takes a few minutes to get.

Trade Name Certificate

While not a business license, Sole Proprietorships and Partnerships operating under a business name that is different from the full name of the owner(s) must register for a Trade Name Certificate (also known as a Doing Business As, DBA, or Fictitious Name) with the Town Clerk’s Office where the business is located.


These are some of the most common business licenses, but there are far too many licenses and permits for us to keep track of. Before starting your business, be sure to check with the Connecticut Licensing Info Center, City Hall, County Clerk, Chamber of Commerce, and/or Economic Developer in your area to get more information regarding business licensing.

For some additional peace of mind, companies like IncFile or CorpNet can do the research and ensure you have all of the proper federal, state, and local licenses to start your business.
