Determine Where Your Company Has Established Nexus
Sales tax nexus is defined as contact with a state that establishes a sufficient connection between a business and a state which may require that the seller registers, collects, and remits sales tax in the state. Certain business activities, including having a physical presence or reaching a specific sales or transaction threshold, may establish nexus with a state. The sales tax nexus standards are changing rapidly since the Wayfair ruling and state-by-state criteria for determining nexus and requirements for compliance are expanding. Determining where your company has established nexus is the first step towards identifying what actions your company should take to become compliant for sales tax.
Establishing a business’s nexus may also require a company to file an income, franchise, gross receipts, and/or other business tax returns. Withum’s State and Local Tax Services Team is available to assist your business with addressing these and other common business issues.
