(2) Special rules
For purposes of this subsection—
(A) Application to partnerships and s corporations
(i) In general
In the case of the credit determined under subsection (a) with respect to any property held directly by a partnership or S corporation, any election under paragraph (1) shall be made by such partnership or S corporation.

(D) Treatment of payments to partnerships and s corporations
For purposes of section 1324 of title 31, United States Code, the payments under subparagraph (A)(i)(I) shall be treated in the same manner as a refund due from a credit provision referred to in subsection (b)(2) of such section.
(E) Additional information
As a condition of, and prior to, any amount being treated as a payment which is made by the taxpayer under paragraph (1) or any payment being made pursuant to subparagraph (A), the Secretary may require such information or registration as the Secretary deems necessary or appropriate for purposes of preventing duplication, fraud, improper payments, or excessive payments under this section.
(F) Excessive payment
(i) In general
In the case of any amount treated as a payment which is made by the taxpayer under paragraph (1), or any payment made pursuant to subparagraph (A), which the Secretary determines constitutes an excessive payment, the tax imposed on such taxpayer by chapter 1 for the taxable year in which such determination is made shall be increased by an amount equal to the sum of—
(I) the amount of such excessive payment, plus
(II) an amount equal to 20 percent of such excessive payment.
(ii) Reasonable cause

For purposes of this subparagraph, the term “excessive payment” means, with respect to property for which an election is made under this subsection for any taxable year, an amount equal to the excess of—
(I) the amount treated as a payment which is made by the taxpayer under paragraph (1), or the amount of the payment made pursuant to subparagraph (A), with respect to such property for such taxable year, over
(II) the amount of the credit which, without application of this subsection, would be otherwise allowable (determined without regard to section 38(c)) under subsection (a) with respect to such property for such taxable year.
(3) Denial of double benefit
In the case of a taxpayer making an election under this subsection with respect to the credit determined under subsection (a), such credit shall be reduced to zero and shall, for any other purposes under this title, be deemed to have been allowed to the taxpayer for such taxable year.
(4) Mirror code possessions
In the case of any possession of the United States with a mirror code tax system (as defined in section 24(k)), this subsection shall not be treated as part of the income tax laws of the United States for purposes of determining the income tax law of such possession unless such possession elects to have this subsection be so treated.
