Each item of the income, gain, loss or deduction of a pass-through entity shall have the same character for a member of such pass-through entity under this title as it has for federal income tax purposes. Where federal income tax rules and principles are not determinative of the character or of the source of an item of income, gain, loss or deduction for purposes of this title, such item shall have the same character or source for a member of the pass-through entity as if the item were realized directly by such member from the source from which realized by the pass-through entity or incurred in the same manner as incurred by the pass-through entity. A member's distributive share of any item of the income, gain, loss or deduction of a pass-through entity shall, solely for purposes of the immediately preceding sentence, be determined by application of the principles of § 704(b) of the Internal Revenue Code [26 U.S.C. § 704(b)], including, without limitation, the principles for determining whether an allocation of such item among the members of such pass-through entity has substantial economic effect.
