What constitutes sales tax nexus in South Carolina?

One of the more complicated aspects of South Carolina sales tax law is sales tax nexus, the determination of whether a particular sale took place within the taxation jurisdiction of South Carolina, and is thus subject to state (and possibly local) sales taxes.

If a vendor's transactions are determined to have nexus in South Carolina, the vendor must register for a South Carolina sales tax license and collect appropriate sales taxes from the buyer for all transactions with nexus in the state. On this page, we have compiled some of the most commonly needed facts about what constitutes sales tax nexus in South Carolina.

Taxation of Internet-Based Sales in South Carolina

NOTE: 2018 Supreme Court Ruling Regarding Online Sales Taxes

In the 2018 Supreme Court case South Dakota vs. Wayfair Inc, Et Al., the court overturned a previous ruling that required a merchant to have physical nexus in order for a state to collect sales tax. This means that any state is now free to enforce collection of sales taxes on out-of-state online merchants. The information provided here may be subject to change, and many states are expected to begin collecting online sales taxes following this ruling.

Generally, South Carolina does not charge sales tax on Internet-based transactions determined to have nexus within the state. This means that purchases from and other Internet-based retailers may be sales-tax-free. Any sort of business that sells tangible, physical personal property by utilizing the Internet and also operates a website, which is maintained with a server that is owned by the seller's business, which is also located within South Carolina's state boundaries, does have nexus. It is possible for other exceptions to be applicable.
