The recent U.S. Supreme Court decision in South Dakota v. Wayfair allows states to impose sales tax on more out-of-state online sales. But does it mean your business must immediately begin collecting sales tax on online sales to all out-of-state customers? No. You must collect such taxes only if the particular state requires it. South Dakota’s law, for example, requires out-of-state retailers that made at least 200 sales or sales totaling at least $100,000 in the state to collect sales tax. But laws vary dramatically from state to state. Contact us with questions.
