Wayfair Decision & Sales Tax Nexus: What Should Remote Sellers Do Now? Self-Study Webinar (2.5 Hours)


In the wake of the US Supreme Court's decision in South Dakota v. Wayfair, states may now require remote sellers with no physical presence in a state to collect sales tax on sales of taxable products and services delivered to customers in that state. In fact, many states have already enacted identical or similar legislation as South Dakota’s, and some Departments have announced their intent to enforce them. As such, it is incumbent on every remote seller to monitor these developments in every state. This self-study webinar is intended to inform tax professionals of this changing landscape, and provide them with the means to address these emerging potential obligations to remote sellers.
