Sales & Use Tax Nexus
Nexus is a sufficient connection (an activity, transaction, property, etc.) between South Carolina and a taxpayer which allows the state to impose its taxing jurisdiction on that taxpayer. A taxpayer with nexus is required to file returns and pay any taxes due.
A taxpayer may have nexus with regard to one or more tax types. For sales tax purposes, nexus is determined when the taxpayer has a physical presence in the state. Out-of-state retailers (remote sellers) that have no physical presence in South Carolina
may have nexus if they meet certain economic thresholds.
