The Supreme Court has issued their ruling in South Dakota v. Wayfair overturning a 1992 ruling that said states can only require sales tax in states that the store has a physical presence. This new ruling says states can require online marketplaces like Amazon to collect and pay sales tax.  This new ruling means that states can now more aggressively go after sellers and require they collect and pay sales tax for orders sent to their states. Former Amazonian John Naughton breaks down to tell us what this ruling means for sellers.
