specified party
(17) The term specified party means a tax resident of the United States, a CFC (other than a CFC with respect to which there is not a tax resident of the United States that, for purposes of sections 951 and 951A, owns (within the meaning of section 958(a), and determined by treating a domestic partnership as foreign) at least ten percent (by vote or value) of the stock of the CFC), and a U.S. taxable branch. Thus, an entity that is fiscally transparent for U.S. tax purposes is not a specified party, though an owner of the entity may be a specified party. For example, in the case of a payment by a partnership, a domestic corporation that is a partner of the partnership is a specified party and a deduction for its allocable share of the payment is subject to disallowance under section 267A.
