Understanding how far back the Georgia Department of Revenue can assess sales tax is a critical part of audit strategy. Statute-of-limitations exposure directly affects potential liability and defense planning. Knowing which rule applies allows businesses to make informed decisions early in the audit process.
Standard Three-Year Audit Rule
For most businesses, Georgia sales tax audits generally cover the most recent three years. This applies when returns were timely filed and substantially correct. In practice, the Department typically limits its review to recent periods unless it identifies significant errors or compliance gaps.
Six-Year Rule for Large Understatements
Georgia may extend the audit lookback period to six years if taxable sales are understated by twenty-five percent or more. This rule disproportionately affects businesses with thin margins or cash-intensive operations, such as restaurants, contractors, and retailers. Even relatively small reporting errors can appear substantial over time and trigger extended review.
Unlimited Lookback for Non-Filers
Businesses that never filed Georgia sales tax returns face unlimited audit exposure. Because the statute of limitations does not begin until a return is filed, the Department may assess tax back to the first taxable sale in Georgia. For remote sellers that ignored post-Wayfair registration requirements, this creates significant retroactive liability for tax, penalties, and interest.
Early voluntary registration or a properly executed Voluntary Disclosure Agreement (VDA) can often limit this exposure. Acting before the Department initiates contact is critical to preserving these options. Timing determines whether the statute can be capped or remains open indefinitely.
Statute-of-limitations rules interact closely with audit timing and protest rights, all of which are explained in our Georgia Sales Tax Audit Ultimate Guide.
