What is nexus?
In New Haven, businesses must understand “nexus” to determine their tax obligations. Nexus refers to the connection that requires a business to collect sales tax in a state. This concept became even more important after the U.S. Supreme Court’s decision in South Dakota v. Wayfair, Inc., which allowed states to require sales tax collection based on economic activity rather than just a physical presence.
