Corporation X is a domestic corporation. Corporation X manufactures widgets in the U.S. for export. Corporation X sells widgets in the United Kingdom through a branch office in London. The London office has its own employees and solicits and processes orders. Corporation X maintains in the U.S. a separate set of books and records for all transactions conducted by the London office. Corporation X is a QBU under paragraph (b)(2)(i) of this section because of its corporate status. The London branch office is a QBU under paragraph (b)(2)(ii) of this section because (1) the sale of widgets is a trade or business as defined in paragraph (c) of this section; and (2) a complete and separate set of books and records (as described in paragraph (d) of this section) is maintained with respect to its sales operations.
A domestic corporation incorporates a wholly-owned subsidiary in Switzerland. The domestic corporation is a manufacturer that markets its product abroad primarily through the Swiss subsidiary. To facilitate sales of the parent's product in Europe, the Swiss subsidiary has branch offices in France and West Germany that are responsible for all marketing operations in those countries. Each branch has its own employees, solicits and processes orders, and maintains a separate set of books and records. The domestic corporation and the Swiss subsidiary are both QBUs under paragraph (b)(2)(i) of this section because of their corporate status. The French and West German branches are QBUs of the Swiss subsidiary. They satisfy paragraph (b)(2)(ii) because each constitutes a trade or business (as defined in paragraph (c) of this section) and because separate sets of books and records (as described in paragraph (d) of this section) of their respective operations is maintained. Each branch is considered to have a trade or business although each is a geographical division of the same trade or business.
W is a domestic corporation that manufactures product X in the United States for sale worldwide. All of W's sales functions are conducted exclusively in the United States. W employs individual Q to work in France. Q's sole function is to act as a courier to deliver sales documents to customers in France. With respect to Q's activities in France, a separate set of books and records as described in paragraph (d) is maintained. Under paragraph (c) of this section, Q's activities in France do not constitute a QBU since they are merely ancillary to W's manufacturing and selling business. Q is not considered to have a QBU because an individual's activities as an employee are not considered to constitute a trade or business of the individual under paragraph (c).
The facts are the same as in example (3) except that the courier function is the sole activity of a wholly-owned French subsidiary of W. Under paragraph (b)(2)(i) of this section, the French subsidiary is considered to be a QBU.
A corporation incorporated in the Netherlands is a subsidiary of a domestic corporation and a holding company for the stock of one or more subsidiaries incorporated in other countries. The Dutch corporation's activities are limited to paying its directors and its administrative expenses, receiving capital contributions from its United States parent corporation, contributing capital to its subsidiaries, receiving dividend distributions from its subsidiaries, and distributing dividends to its domestic parent corporation. Under paragraph (b)(2)(i) of this section, the Netherlands corporation is considered to be a QBU.
Taxpayer A, an individual resident of the United States, is engaged in a trade or business wholly unrelated to any type of investment activity. A also maintains a portfolio of foreign currency-denominated investments through a foreign broker. The broker is responsible for all activities necessary to the management of A's investments and maintains books and records as described in paragraph (d) of this section, with respect to all investment activities of A. A's investment activities qualify as a QBU under paragraph (b)(2)(ii) of this section to the extent the activities engaged in by A generate expenses that are deductible under section 212 (other than that part of section 212 dealing with expenses incurred in connection with taxes).
Taxpayer A, an individual resident of the United States, is the sole shareholder of foreign corporation (FC) whose activities are limited to trading in stocks and securities. FC is a QBU under paragraph (b)(2)(i) of this section.
Taxpayer A, an individual resident of the United States, markets and sells in Spain and in the United States various products produced by other United States manufacturers. A has an office and employs a salesman to manage A's activities in Spain, maintains a separate set of books and records with respect to his activities in Spain, and is engaged in a trade or business as defined in paragraph (c) of this section. Therefore, under paragraph (b)(2)(ii) of this section, the activities of A in Spain are considered to be a QBU.
Foreign corporation FX is incorporated in Mexico and is wholly owned by a domestic corporation. The domestic corporation elects to treat FX as a domestic corporation under section 1504(d). FX operates entirely in Mexico and maintains a separate set of books and records with respect to its activities in Mexico. FX is a QBU under paragraph (b)(2)(i) of this section. The activities of FX in Mexico also constitute a QBU under paragraph (b)(2)(ii) of this section.
F, a foreign corporation, computes a gain of $100 from the disposition of a United States real property interest (as defined in section 897(c)). The gain is taken into account as if F were engaged in a trade or business in the United States and as if such gain were effectively connected with such trade or business. F is a QBU under paragraph (b)(2)(i) of this section because of its corporate status. F's disposition activity constitutes a separate QBU under paragraph (b)(3) of this section.
