​​Income 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 that are due. A taxpayer may have nexus with regard to one or more tax types. For income tax purposes, economic nexus is generally sufficient to create nexus even without a physical presence in the state.

*Note: Income Nexus includes: "C" and "S" Corporations, Partnerships, Limited Liability, Companies, and Sole Proprietors.
