Important Update:  On June 21, 2018, the U.S. Supreme Court rendered its opinion in South Dakota v. Wayfair and overturned the Quill physical presence standard. Since the Wayfair decision, several states have also adopted economic nexus for sales tax - and it's expected that more will follow. 

Find out which states have adopted nexus by viewing our updated Economic Nexus blog post. Also see our Questions and Answers for Foreign Sellers and article on the U.S. Supreme Court Wayfair decision (link for all below).
