Requirements for Taxpayers Filing Form 5472

This document contains final regulations on Form 5472, "Information Return of a 25% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business." The final regulations affect certain 25-percent foreign-owned domestic corporations and certain foreign corporations that are engaged in a trade or business in the United States that are required to file Form 5472. Contemporaneously, new proposed regulations are being issued that would remove a current provision for timely filing of Form 5472 separately from an income tax return that is untimely filed. As a result, the proposed regulations would require Form 5472 to be filed in all cases only with the filer's income tax return for the taxable year by the due date (including extensions) of that return.
