(a) Inverted domestic corporations are covered not only in the Department of Homeland Security statute at 6 U.S.C. 395, but also are similarly covered in the Internal Revenue Code at 26 U.S.C. 7874. A foreign corporation is treated as an inverted domestic corporation for U.S. Federal income tax purposes, rather than as a foreign corporation, if-
(1) At least 80 percent (80%) of the stock is now held by former shareholders of the domestic corporation or partners of the domestic partnership; and
(2) The foreign entity plus companies connected to it by 50 percent (50%) or more ownership do not have substantial business activities in the foreign country.
(b) A foreign corporation that is treated as an inverted domestic corporation for U.S. Federal income tax purposes, is also treated as one for purposes of this section.
(c) A foreign entity that escapes the tax consequence of 26 U.S.C. 7874 only because the inversion transactions were completed on or before the March 4, 2003, date in section 7874, is nevertheless treated as an inverted domestic corporation for purposes of 6 U.S.C. 395 (which does not have a limiting date) and therefore also for purposes of this section.
