FAQ about sales tax compliance

Sales tax compliance refers to the complete process of properly collecting, reporting, and remitting sales tax to appropriate state and local authorities according to all applicable laws and regulations. It encompasses determining where you have nexus and must register, calculating correct tax amounts on every transaction, collecting tax from customers, maintaining accurate records, filing periodic returns on schedule, and remitting collected taxes to authorities by deadlines. Proper sales tax compliance is critical because failures result in significant penalties, interest charges on unpaid taxes, potential audits, legal issues, and reputational damage. States are increasingly aggressive about enforcement, using data sharing and sophisticated analytics to identify non-compliant businesses, making professional compliance management essential rather than optional.
