This Portfolio is available with a subscription to Bloomberg Tax, a comprehensive research solution including over 500 Tax Management Portfolios, practice tools, primary sources and timely news.


The Portfolio begins with a discussion of the background and legislative history of Subpart F. A detailed analysis is provided of the ownership tests that must be satisfied for Subpart F to apply, including such key terms as “controlled foreign corporation,” “United States person,” and “United States shareholder.”

This Portfolio also describes the categories of items included in U.S. Shareholders' income under Subpart F, and the rules for determining the amounts includible in income and the U.S. tax treatment. It further provides an overview of the tax results to U.S. Shareholders of various transactions involving CFCs, including the organization and reorganization of a CFC, CFC distributions, and liquidations and dispositions of CFCs. Finally, it describes the rules coordinating Subpart F with other special rules that apply to foreign entities and summarizes the return and compliance rules that apply to CFCs. Because the CFC Portfolios are meant to be used as a group in analyzing the Subpart F rules, the Worksheets of this Portfolio are intended for use not only with this Portfolio but also with the other CFC Portfolios.
