For purposes of this title, except as provided in subsection (c), a publicly traded partnership shall be treated as a corporation.
Subsection (a) shall not apply to any publicly traded partnership for any taxable year if such partnership met the gross income requirements of paragraph (2) for such taxable year and each preceding taxable year beginning after December 31, 1987, during which the partnership (or any predecessor) was in existence. For purposes of the preceding sentence, a partnership shall not be treated as being in existence during any period before the 1st taxable year in which such partnership (or a predecessor) was a publicly traded partnership.
A partnership meets the gross income requirements of this paragraph for any taxable year if 90 percent or more of the gross income of such partnership for such taxable year consists of qualifying income.
This subsection shall not apply to any partnership which would be described in section 851(a) if such partnership were a domestic corporation. To the extent provided in regulations, the preceding sentence shall not apply to any partnership a principal activity of which is the buying and selling of commodities (not described in section 1221(a)(1)), or options, futures, or forwards with respect to commodities.
The term “qualifying income” also includes any income which would qualify under section 851(b)(2)(A) or 856(c)(2).
Subsection (a) shall not apply to an electing 1987 partnership.
There is hereby imposed for each taxable year on the income of each electing 1987 partnership a tax equal to 3.5 percent of such partnership’s gross income for the taxable year from the active conduct of trades and businesses by the partnership.
For purposes of this paragraph, in the case of a partnership which is a partner in another partnership, the gross income referred to in subparagraph (A) shall include the partnership’s distributive share of the gross income of such other partnership from the active conduct of trades and businesses of such other partnership. A similar rule shall apply in the case of lower-tiered partnerships.
For purposes of this title, the tax imposed by this paragraph shall be treated as imposed by chapter 1 other than for purposes of determining the amount of any credit allowable under chapter 1 and shall be paid by the partnership. Section 6655 shall be applied to such partnership with respect to such tax in the same manner as if the partnership were a corporation, such tax were imposed by section 11, and references in such section to taxable income were references to the gross income referred to in subparagraph (A).
An election and consent under this subsection shall apply to the taxable year for which made and all subsequent taxable years unless revoked by the partnership. Such revocation may be made without the consent of the Secretary, but, once so revoked, may not be reinstated.
