Important Update:

On June 21, 2018, the U.S. Supreme Court held in favor of the state in South Dakota v. Wayfair and overturned the Quill physical presence standard. Since the Supreme Court decision, several states have also adopted economic nexus for sales tax - and it's expected that more will follow. You can find out which states have adopted nexus by viewing our updated Economic Nexus blog post OR downloading our Economic Nexus chart  (the blog post chart is updated every few days, the pdf chart is only updated once a month).
