Do I need a sales tax permit in Connecticut?

According to the Connecticut Department of Revenue Services, you must obtain a sales tax permit (called a Sale and Use Tax Permit in Connecticut) before doing the following in Connecticut:

• Selling, renting, or leasing goods
• Selling a taxable service
• Operating a hotel, motel, or lodging service

You do not need a sales tax permit if you make an isolated sale—for example, if you sell your bike to a guy on Craigslist. The Department of Revenue also states that if you purchase a business from someone else, you must obtain a new sales tax permit, rather than using the previous owner’s permit.
