How to Start a E-commerce Business in Connecticut
Selling physical products online through your own store or marketplaces. Here's the Connecticut-specific path — structure, licensing for e-commerce work, taxes, insurance, and landing your first customers.
Licensing for e-commerce work in Connecticut
You need a seller's permit in your home state and must monitor economic nexus in other states (register once your sales there cross a threshold, often $100k or 200 transactions). Marketplace facilitator laws mean Amazon/Etsy often collect tax for you. In Connecticut, check both your city/county and the relevant state board before you advertise.
What a e-commerce business needs to open
Selling physical products online through your own store or marketplaces. The setup areas that usually matter: Seller's permit + economic-nexus sales tax, Resale certificate for wholesale, Store platform + payments, Fulfillment (self, 3PL, or dropship), Product liability considerations. Typical cost to get operational: $1,000–$20,000 (inventory is the variable).
Pick a structure (sole proprietor or LLC)
Most Connecticut owners start as a sole proprietor (free, no filing) or form an LLC for liability protection. The LLC filing fee is about $120, and formation typically takes about 3–5 business days online. Confirm the current fee on the state site before you pay.
Name a registered agent
If you form an LLC or corporation, Connecticut needs a registered agent with a physical in-state address. You can be your own agent if you're available during business hours, or hire a service for about $100–$150/year.
Get your EIN from the IRS
An Employer Identification Number is free from the IRS and takes a few minutes online. You need it to open a business bank account and to hire.
Register for Connecticut taxes
Connecticut has a state sales/use tax and has a state income tax. Connecticut's annual report fee is $80 and due by the anniversary month.
Confirm local licenses and permits
Connecticut rarely issues a single statewide "business license" — most licensing is by city or county, plus profession-specific licenses. Check your city and your trade.
Open a business bank account and get insurance
Keep business and personal money separate from day one. General liability insurance is the baseline; some contracts also require a bond.
Put the ongoing report on your calendar
Connecticut requires a annual report (about $80).
