Form 3520-A is the annual information return of a foreign trust with at least one U.S. owner. The form provides information about the foreign trust, its U.S. beneficiaries, and any U.S. person who is treated as an owner of any portion of the foreign trust.

A foreign trust with a U.S. owner must file Form 3520-A in order for the U.S. owner to satisfy its annual information reporting requirements under section 6048(b). Each U.S. person treated as an owner of any portion of a foreign trust under sections 671 through 679 is responsible for ensuring that the foreign trust files Form 3520-A and furnishes the required annual statements to its U.S. owners and U.S. beneficiaries.
