Marketplace Seller laws in South Carolina

In South Carolina, online marketplace sellers may be subject to sales tax obligations. This means that depending on their sales activity and physical presence, or economic presence, within the state, they might be required to register with the state tax authority, collect sales tax from customers, and remit those taxes. The determination of whether a seller has an obligation to collect sales tax is often referred to as establishing 'nexus'. Nexus can be established through various means, including having a physical presence like an office or employees, or meeting certain economic thresholds based on sales volume or transaction count within the state. Marketplace facilitators, which are platforms that process sales for third-party sellers, may also have their own responsibilities to collect and remit sales tax on behalf of their sellers. Understanding these obligations is crucial for compliance. The legal framework aims to ensure fair competition between online and brick-and-mortar retailers and to generate revenue for the state. Sellers should regularly review their activities and understand the current interpretations of sales tax laws to avoid potential issues.
