Who has to pay sales or use tax to Connecticut?
In general, a business must collect and remit all applicable sales taxes if that business has nexus, a physical presence such as a brick-and-mortar location, within a given state. The presence of an employee or salesperson, delivery by the seller's vehicle, and storage of materials usually establishes nexus as well.
Connecticut says that an out-of-state seller is required to collect tax if they can be defined as a "retailer engaging in business". Connecticut does not currently have additional laws establishing nexus for other reasons such as out-of-state businesses using in-state affiliates, advertisers or vendors, or businesses that make internet sales or mail catalogs.

Since Connecticut legislators can vote to change sales and use tax rates at any time, it is very difficult for individuals to keep track of the changes. The population of CT state is also rapidly changing, which can cause frequent updates to the ZIP codes and local municipality names and complicates the job of keeping track of sales tax jurisdictions.
