1. Short title This Act may be cited as the Basis Shifting is a Rip-off Act . 2. Rules for basis-shifting transactions involving related parties (a) Distributions (1) Recognition of gain Section 731 of the Internal Revenue Code of 1986 is amended by striking subsections (a) and (b) and inserting the following: (a) Partners (1) In general In the case of a distribution by a partnership to a partner— (A) gain shall not be recognized to such partner, except to the extent that any money distributed exceeds the adjusted basis of such partner's interest in the partnership immediately before the distribution, and (B) loss shall not be recognized to such partner, except that upon a distribution in liquidation of a partner's interest in a partnership where no property other than that described in clause (i) or (ii) is distributed to such partner, loss shall be recognized to the extent of the excess of the adjusted basis of such partner's interest in the partnership over the sum of— (i) any money distributed, and (ii) the basis to the distributee, as determined under section 732, of any unrealized receivables (as defined in section 751(c)) and inventory (as defined in section 751(d)). Any gain or loss recognized under this paragraph shall be considered as gain or loss from the sale or exchange of the partnership interest of the distributee partner. (2) Exception for certain related-party partnership distributions Notwithstanding paragraph (1)(A)— (A) In general In the case of any distribution of property to which section 732(a)(2) or (b) applies which is made from an applicable partnership to a partner (including as part of the termination of such partnership), such partner shall, in addition to any amount which would be recognized without regard to this subparagraph, recognize gain in an amount equal to the applicable basis increase. (B) Applicable basis increase For purposes of this paragraph, the term applicable basis increase means, with respect to any distribution of any property described in subparagraph (A) to a partner, the aggregate increases in basis to one or more partnership properties under section 734(b)(1)(B) (without regard to whether any such increase is suspended under section 755) with respect to such distribution. (C) Basis adjustment In the case of each distributed property with respect to which gain is recognized by reason of subparagraph (A), the basis of such property after the distribution shall be the basis determined under section 732, increased by the amount of such gain with respect to such property. (D) Character of gain (i) In general If a distribution of any property to which subparagraph (A) applies results in any portion of any applicable basis increase in partnership property under section 734(b)(1)(B), gain under subparagraph (A) with respect to such distributed property shall have the same character as gain from the sale or exchange of the partnership property to which such portion is allocated under section 755. (ii) Special rule where basis increase suspended (I) In general If the allocation under section 755 of any portion of an applicable basis increase described in clause (i) is suspended under such section by the absence of property, or insufficient adjusted basis in property, to which such portion is to be so allocated, gain under subparagraph (A) with respect to such distributed property shall be treated as ordinary income. (II) Secretarial authority The Secretary may provide that subclause (I) shall not apply in cases where the Secretary determines necessary and appropriate to carry out, or prevent avoidance of, the purposes of this paragraph. (E) Coordination with marketable securities rules If any property described in subparagraph (A) consists of marketable securities (as defined in subsection (c)(2))— (i) this paragraph shall apply to such property before the application of subsection (c), and (ii) in applying subsection (c), the basis of such property shall be the basis determined after the application of subparagraph (C). The Secretary shall provide rules for the application of this subparagraph, including coordination of the application of this subparagraph with subsection (c) and the other provisions of this subchapter. (b) Partnerships (1) In general Except as provided in paragraph (2), no gain or loss shall be recognized to a partnership on a distribution to a partner of property, including money. (2) Exception for certain related-party partnership distributions (A) In general In the case of any distribution of property from an applicable partnership to a partner which under section 732(c) results in an increase in basis in one or more properties so distributed, gain shall be recognized to the partnership in an amount equal to the aggregate amount of such increases in basis. (B) Basis adjustment In the case of each partnership property with respect to which gain is recognized by reason of subparagraph (A), the basis of such property after the distribution shall be the basis determined under section 734, increased by the amount of such gain with respect to such property. (C) Character of gain Any gain recognized under this paragraph which is allocable to a portion of any basis increase in distributed property described in subparagraph (A) shall have the same character as gain from the sale or exchange of such property. . (2) Applicable partnership Section 731 of such Code is amended by adding at the end the following new subsections: (e) Applicable partnership For purposes of this section— (1) In general The term applicable partnership means any partnership in which two or more partners are related persons immediately before or after any distribution to a partner. (2) Small business exception (A) In general A partnership shall not be treated as an applicable partnership with respect to any distribution made during a taxable year if such partnership meets the gross receipts test under section 448(c) (determined with the modification described in subparagraph (C)) for such taxable year.
