How to start a business in Connecticut.

Business formation in Connecticut runs through the Connecticut Secretary of the State (Business One Stop), the official government office. You can file there directly for just the state's own filing fee, and nobody can legalize your business "better" than the state itself. Fees change, so the current number is always on the official site.

Why Connecticut is a great place to build.

Connecticut has one of the highest household incomes in the country, concentrated in commuter towns within reach of New York City, which means real spending power for premium services. Hartford's insurance base and New Haven's biotech cluster anchor a stable professional economy. If your business serves an affluent, discerning customer, the demand is here.

Local help for Connecticut founders.

Connecticut founders have real, free help within reach. The state's Small Business Development Center (SBDC) network offers no-cost advising, and volunteer mentors through SCORE chapters have built businesses like yours. The Secretary of State and state commerce resources publish plain guides on formation, licensing, and taxes, so lean on them before you ever pay a middleman.

Connecticut, specifically.

Connecticut blends New England history with serious wealth, from the insurance towers of Hartford to the coastal estates of Fairfield County. Yale gives New Haven a brainy, biotech edge. It is a state where quality and reputation matter, and where a premium service done right can command premium prices.

The six steps, in order

1. 1

   Pick your business structure

   Most first businesses in Connecticut choose an LLC for the liability separation between the business and your personal life. Sole proprietorships are simpler but offer no separation; corporations fit businesses raising investment.

2. 2

   Check that your business name is free

   Search the Connecticut Secretary of the State (Business One Stop)'s business registry to confirm nobody in Connecticut already holds the name, and check the matching web domain at the same time. Our free name generator checks the domain with every name it suggests.

3. 3

   File your formation documents with the Connecticut Secretary of the State (Business One Stop)

   This is the official step that makes the business real. File directly on the state's own site and pay only Connecticut's filing fee. Every state requires a registered agent with a physical address in the state; if you live in Connecticut, you can usually be your own.

4. 4

   Get your EIN free from the IRS

   The Employer Identification Number is the business's tax ID. The IRS issues it directly at irs.gov in about five minutes, at no charge. Never pay anyone for an EIN alone. Get the EIN at irs.gov ↗

5. 5

   Check for licenses and permits

   Many businesses also need a city or county business license, and some industries need Connecticut state licenses. The Connecticut Secretary of the State (Business One Stop)'s site and your city hall list what applies.

6. 6

   Open the business bank account and connect payments

   Keep business money separate from day one: it protects the legal separation your LLC exists for and keeps taxes clean. Bring your EIN and formation documents to the bank. Our free Get Paid directory lists business banks and payment processors in the order to set them up.
