PFIC Reporting & Form 8621 Filing Requirements

PFIC reporting is the U.S. tax reporting process for U.S. taxpayers who own a Passive Foreign Investment Company, including many foreign ETFs, mutual funds, and offshore investment funds. Form 8621 is used to report PFIC ownership, excess distributions, dispositions, QEF elections, and mark-to-market (MTM) elections under IRC §§1291, 1295, and 1296.

PFIC Report provides technical guidance and calculation support for U.S. taxpayers, expats, CPAs, and EAs dealing with Form 8621 filing requirements, PFIC classification, §1291 tax calculations, MTM and QEF elections, and supporting workpapers.
