Protective Claim

A protective claim is a procedural tool used by taxpayers to keep a refund request open when the statute of limitations is about to expire, but the legal basis for the refund depends on a future event, such as a pending court case (like the Kwong v. United States appeal). When a protective claim is filed, the IRS holds the request in a pending status ('suspense') and does not act on it until the underlying case or litigation is finalized. This protects the taxpayer from missing the strict three-year or two-year refund request windows.

Real-World Example A taxpayer paid late-filing penalties during the COVID-19 pandemic. Under Kwong v. United States, a court ruled that pandemic emergency declarations automatically postponed tax deadlines, rendering those penalties invalid. However, since the IRS is appealing the ruling, the taxpayer files a Form 843 protective claim by the July 10, 2026 deadline. This preserves their legal right to a refund, meaning if the court of appeals eventually rules in favor of the taxpayers, the IRS will issue their refund. If they did not file this protective claim, they would receive nothing once the deadline passed.
