Sales tax compliance often gets reduced to one task: filing returns. In reality, it’s an ongoing, multi-step process that becomes more complex as businesses grow across states, sales channels, and product lines.
Since the South Dakota v. Wayfair decision, companies are managing sales tax obligations across 46 states and Washington, D.C., with more than 10,000 jurisdictions, each with its own rules, rates, and filing requirements. Even small errors can lead to penalties, interest, and audits.
