Economic Nexus Laws by State: Connecticut

State laws on economic nexus vary and it’s hard to keep up if you’re doing business in multiple states. We’ve done the research for you and here’s all the information you need to know about economic nexus in Connecticut.

What is economic nexus in Connecticut?

With the recent South Dakota v. Wayfair Supreme Court ruling in favor of South Dakota, states are now free to pursue sales tax from eCommerce businesses who have a “significant presence” in their state.

Significant presence or “nexus” was previously defined as having a physical presence (ex: a brick & mortar store, employee or inventory in a fulfillment center like FBA). But with this recent ruling, now this definition has been expanded to include economic activity in a state as well. This concept of triggering sales tax responsibility because of your economic activity in a state is now referred to as economic nexus.

Most importantly, what this means is that if you pass a state’s economic threshold for total revenue in that state and/or number of transactions in that state, you’re now legally required to register, collect and remit sales tax for that state.

What’s the threshold for economic nexus law in Connecticut?

  • State: Connecticut
  • Threshold: At least 200 Connecticut sales during the preceding 12-month period ending September 30; and gross receipts are $100,000 or more during that period.
  • Summary:According to state law, sellers who exceed the gross sales AND transaction number are required to register for a Connecticut sales tax permit, collect sales tax on sales that ship to Connecticut, and remit the sales tax to the state.

When did this Connecticut law go into effect or is it planned?

This law will go into effect 7/1/2019.
