Rocket Tip: If you haven't yet started an LLC and want help getting business licenses and permits, some LLC services can help you take care of those requirements as part of their packages. LegalZoom and Incfile being the two most popular.
Are There Federal Licenses That My Business Needs?
First off, let’s discuss the matter of federal licenses and permits. There are many business activities that are regulated by various federal agencies, from agriculture to transportation and logistics. We recommend taking a look at the U.S. Small Business Administration’s guide to federal licenses and permits to make sure you’ve got your bases covered.
In addition, most businesses should acquire a federal tax ID number, also known as an EIN (employer identification number). This is essentially a social security number for your business, and it enables you to hire employees, pay business taxes, open business bank accounts, and more. You can acquire an EIN from the IRS for free.
What State-Level Licenses and Permits Apply in Connecticut?
The state of Connecticut does not have a general business license that applies statewide to every business entity, as some states do. However, depending on the nature of your business, there could be several licenses and/or permits that you may be required to obtain.
To determine which permits you need to operate a compliant business, we recommend that you pay a visit to the Connecticut Economic Resource Center, where you can conduct a license search for your industry.
Occupational Licenses and Permits
The occupational licenses and permits required by the state of Connecticut vary widely, from architecture to well drilling, and many points in between. Depending on the exact nature of your business, you might need more than one of these permits. Thankfully, the Department of Consumer Protection keeps a database of all occupational licenses and instructions to register on their website.
Environmental Licenses and Permits
Finally, Connecticut also has some environmental permits for air emissions, water and land use, and waste and materials management. You can learn more about state environmental requirements on the Department of Energy & Environmental Protection website.
Which Tax Registrations are Required for Connecticut Businesses?
In addition to occupational licenses and permits, there are a number of state-level tax registrations, which are based on the industry you operate in and which business structure your company uses.
Every Connecticut limited liability company is required to register for the Business Entity Tax, which includes payment of $250 once every two years. Corporations must register and pay the Corporation Business Tax. Most businesses will also need to pay sales and use tax in Connecticut.
There are also many industry-specific tax registrations and credits in the state of Connecticut, from film production to historic home renovation. Thankfully, the Connecticut Department of Revenue handles tax registrations, and also helps businesses better understand their tax obligations. You can learn more at this link.
Are There Local Licenses, Permits, or Registrations in Connecticut?
The answer to this question obviously depends on where in Connecticut you’re operating your business, but there are indeed quite a few licenses, permits, and tax registrations required by Connecticut localities.
All local occupational license forms are managed at the county level, including those in Fairfield, New Haven, Hartford, Litchfield, Windham, Middlesex, Tolland, and New London. You can consult your county’s website for more information.
There are also some requirements on the city/municipality level. For example, Bridgeport, New Haven, Stamford, and Hartford all have business resource websites that explain the applicable permits and licenses required to do business.
If we were to break down the exact rules and regulations regarding permitting in every locality in the state of Connecticut, this article would become excessively lengthy. With that in mind, we’ll simply say that every business owner should check with their local government to determine whether there are licenses, permits, or tax registrations required to operate in compliant fashion.
Can I Hire Someone to Research Licenses and Permits for My Business?
If this process sounds like a bit of a hassle, that’s because it certainly can be. If you would rather hire a reputable business services provider to handle this for you, that is always an option.
