As a business, do I need to collect Connecticut sales tax?

Businesses are required to collect sales tax in Connecticut if they have a sales tax nexus in the state. This includes having a physical presence or reaching a specific sales level, which establishes an economic nexus. This is why understanding Connecticut state sales tax obligations is crucial for compliance.


Do I have a physical nexus in Connecticut?

They operate their own businesses and are not typically under the direct control of the hiring company. The presence of contractors engaged in customer-facing roles, such as marketing, sales, support, or servicing, usually triggers a physical nexus in the state.
  • Employees (customer facing roles): In the context of establishing a physical nexus, "employees" refer to individuals who work for your business and are physically present in the respective state.

How do I know if I have an economic nexus in Connecticut?

An economic nexus in Connecticut is determined by your sales volume. If the annual sales of your enterprise exceed the given threshold in Connecticut, you must register for an Connecticut sales tax permit, collect tax on sales shipped to Connecticut, and remit that sales tax to the state revenue authorities.

In Connecticut, an economic nexus is established for your enterprise if your sales in the state exceed 100000 AND number of transactions exceed 200, based on the sales from the 12-month period ending on September 30.

While calculating the sales or number of transactions for determining economic nexus, Connecticut requires transactions made through marketplaces, like Amazon, eBay, etc. to be included. Transactions made for resale purposes should be excluded while determining whether a business has exceeded the Connecticut economic nexus threshold.
