The United States Supreme Court has agreed to hear South Dakota's appeal in the case of State of South Dakota v. Wayfair, SD SC, Case No. 28160. (Order Granting Certiorari, January 12, 2018)

South Dakota enacted a law that required out of state sellers who sell over $100,000 in a year and have 200 or more distinct transactions to collect and remit sale tax for the state of South Dakota regardless of whether or not the seller has nexus with the state of South Dakota.

Shoud the Supreme Court decide in South Dakota's favor, it could radically expand the number of states tha a business would be required to collect and remit sales taxes for.
