Sales and use tax compliance can involve navigating a myriad of tax jurisdictions, each with their own rules, rates, and definitions. As product lines evolve, exemptions shift, and economic nexus rules expand, 100% accuracy becomes a demanding task—even for the most well-organized tax departments.
That’s where a reverse audit can make a real impact. In this on-demand webinar, we’ll explore how reverse audits help strengthen your broader compliance efforts. You’ll walk away with a clear understanding of how the process works, where refund opportunities often hide, and how to use this insight to reduce risk and improve future outcomes.
At a time when state and local tax enforcement is ramping up, reviewing your historical filings isn’t just a good idea—it’s a strategic one. Reverse audits allow you to take a fresh look at past activity, catch discrepancies early, and claim eligible refunds before statute of limitations windows close.
Larry Mellon of Vertex, Inc. and our own Trisha Davidson will guide you through the reverse audit process from start to finish, share real-world examples of tax recovery, and explain how to use the findings to streamline your internal systems.

During this 90 minute on-demand training, attendees will gain a practical understanding of how reverse audits work and why they’re a powerful, often underutilized, tool for businesses. We will walk through the full reverse audit process, including how to identify potential refund opportunities, gather supporting documentation, and navigate refund claims with state tax authorities.
You’ll also learn how reverse audits differ from traditional audits and why they can play a critical role in your overall tax strategy. We’ll highlight common areas where overpayments occur, such as misclassified purchases, overlooked exemptions, or system setup issues. Although reverse audits typically only focus on tax on purchases, we’ll talk about when a reverse audit can be used to recover tax due to the seller on the sales transaction. We will also cover why this matters so much for businesses that operate across multiple states or use complex ERP systems.
Beyond recovery, we’ll explore how the insights gained from a reverse audit can improve your long-term compliance. Attendees will gain practical tips on how to prevent recurring issues, improve exemption certificate management, and align internal processes for greater accuracy and efficiency.
Whether you’re new to reverse audits or looking to refine your approach, this session will provide actionable guidance you can put to use immediately.
