## About Form 8621 Calculator
Form 8621 is a U.S. tax form used to report income, gains, and other information from a Passive Foreign Investment Company (PFIC). U.S. taxpayers with direct or indirect ownership in a PFIC must file it to avoid punitive tax treatment and interest charges. Our Form 8621 Calculator walks you through the process step by step and automatically computes everything for you—saving time and helping you file with confidence.
