On June 21, 2018, the Supreme Court of the United States announced a decision in the South Dakota v. Wayfair Inc. case. In short, South Dakota argued that it was losing out on local sales taxes as consumers spent more money shopping online rather than in brick-and-mortar locations. The 1992 Quill Corp v. North Dakota case had set a precedent for how states would eventually deal with online retailers. Back then, the court ruled in favor of Quill Corp, which it agreed did not need to collect sales tax on sales in North Dakota because it had no physical presence in the state.
The June 21st decision in 2018 by SCOTUS wipes out that precedent and opens the door for states to begin forcing online retailers to collect and remit local sales taxes. Online retailers are now forced with adapting to a variety of different sales tax rates and rules across the nation.
As a small business with a single nexus of business, we are currently required to collect taxes in only the state of North Carolina, subject to change at any time.
