(B) the aggregate credit which would be allowable by reason of this section for such years with respect to such basis if the aggregate credit which would (but for this subsection) have been allowable for the entire compliance period were allowable ratably over 15 years.

The Secretary may provide that the increase in tax under this subsection shall not apply with respect to any building if—

(A) Tax benefit rule The tax for the taxable year shall be increased under paragraph (1) only with respect to credits allowed by reason of this section which were used to reduce tax liability. In the case of credits not so used to reduce tax liability, the carryforwards and carrybacks under section 39 shall be appropriately adjusted.

(B) Only basis for which credit allowed taken into account Qualified basis shall be taken into account under paragraph (1)(B) only to the extent such basis was taken into account in determining the credit under subsection (a) for the preceding taxable year referred to in such paragraph.

(C) No recapture of additional credit allowable by reason of subsection (f)(3) Paragraph (1) shall apply to a decrease in qualified basis only to the extent such decrease exceeds the amount of qualified basis with respect to which a credit was allowable for the taxable year referred to in paragraph (1)(B) by reason of subsection (f)(3).

(D) No credits against tax Any increase in tax under this subsection shall not be treated as a tax imposed by this chapter for purposes of determining the amount of any credit under this chapter.

(E) No recapture by reason of casualty loss The increase in tax under this subsection shall not apply to a reduction in qualified basis by reason of a casualty loss to the extent such loss is restored by reconstruction or replacement within a reasonable period established by the Secretary.

(F) No recapture where de minimis changes in floor spaceThe Secretary may provide that the increase in tax under this subsection shall not apply with respect to any building if— (i) such increase results from a de minimis change in the floor space fraction under subsection (c)(1), and (ii) the building is a qualified low-income building after such change.

For purposes of applying this subsection to a partnership to which this paragraph applies—

(A) In generalFor purposes of applying this subsection to a partnership to which this paragraph applies— (i) such partnership shall be treated as the taxpayer to which the credit allowable under subsection (a) was allowed, (ii) the amount of such credit allowed shall be treated as the amount which would have been allowed to the partnership were such credit allowable to such partnership, (iii) paragraph (4)(A) shall not apply, and (iv) the amount of the increase in tax under this subsection for any taxable year shall be allocated among the partners of such partnership in the same manner as such partnership’s taxable income for such year is allocated among such partners.

(B) Partnerships to which paragraph applies This paragraph shall apply to any partnership which has 35 or more partners unless the partnership elects not to have this paragraph apply.

(C) Special rules (i) Husband and wife treated as 1 partner For purposes of subparagraph (B)(i), a husband and wife (and their estates) shall be treated as 1 partner. (ii) Election irrevocable Any election under subparagraph (B), once made, shall be irrevocable.

If a building (or an interest therein) is disposed of during any taxable year and there is any reduction in the qualified basis of such building which results in an increase in tax under this subsection for such taxable or any subsequent taxable year, then—

(A) In general The increase in tax under this subsection shall not apply solely by reason of the disposition of a building (or an interest therein) if it is reasonably expected that such building will continue to be operated as a qualified low-income building for the remaining compliance period with respect to such building.

(B) Statute of limitationsIf a building (or an interest therein) is disposed of during any taxable year and there is any reduction in the qualified basis of such building which results in an increase in tax under this subsection for such taxable or any subsequent taxable year, then— (i) the statutory period for the assessment of any deficiency with respect to such increase in tax shall not expire before the expiration of 3 years from the date the Secretary is notified by the taxpayer (in such manner as the Secretary may prescribe) of such reduction in qualified basis, and (ii) such deficiency may be assessed before the expiration of such 3-year period notwithstanding the provisions of any other law or rule of law which would otherwise prevent such assessment.

For purposes of this section—

(1) In general Except as otherwise provided in this subsection, rules similar to the rules of section 49(a)(1) (other than subparagraphs (D)(ii)(II) and (D)(iv)(I) thereof), section 49(a)(2), and section 49(b)(1) shall apply in determining the qualified basis of any building in the same manner as such sections apply in determining the credit base of property.

For purposes of paragraph (1)—

(A) In generalIf the requirements of subparagraphs (B), (C), and (D) are met with respect to any financing borrowed from a qualified nonprofit organization (as defined in subsection (h)(5)), the determination of whether such financing is qualified commercial financing with respect to any qualified low-income building shall be made without regard to whether such organization— (i) is actively and regularly engaged in the business of lending money, or (ii) is a person described in section 49(a)(1)(D)(iv)(II).

(B) Financing secured by propertyThe requirements of this subparagraph are met with respect to any financing if such financing is secured by the qualified low-income building, except that this subparagraph shall not apply in the case of a federally assisted building described in subsection (d)(6)(C) if— (i) a security interest in such building is not permitted by a Federal agency holding or insuring the mortgage secured by such building, and (ii) the proceeds from the financing (if any) are applied to acquire or improve such building.

(C) Portion of building attributable to financing The requirements of this subparagraph are met with respect to any financing for any taxable year in the compliance period if, as of the close of such taxable year, not more than 60 percent of the eligible basis of the qualified low-income building is attributable to such financing (reduced by the principal and interest of any governmental financing which is part of a wrap-around mortgage involving such financing).

(D) Repayment of principal and interestThe requirements of this subparagraph are met with respect to any financing if such financing is fully repaid on or before the earliest of— (i) the date on which such financing matures, (ii) the 90th day after the close of the compliance period with respect to the qualified low-income building, or (iii) the date of its refinancing or the sale of the building to which such financing relates. In the case of a qualified nonprofit organization which is not described in section 49(a)(1)(D)(iv)(II) with respect to a building, clause (ii) of this subparagraph shall be applied as if the date described therein were the 90th day after the earlier of the date the building ceases to be a qualified low-income building or the date which is 15 years after the close of a compliance period with respect thereto.

(3) Present value of financing If the rate of interest on any financing described in paragraph (2)(A) is less than the rate which is 1 percentage point below the applicable Federal rate as of the time such financing is incurred, then the qualified basis (to which such financing relates) of the qualified low-income building shall be the present value of the amount of such financing, using as the discount rate such applicable Federal rate. For purposes of the preceding sentence, the rate of interest on any financing shall be determined by treating interest to the extent of government subsidies as not payable.

To the extent that the requirements of paragraph (2)(D) are not met, then the taxpayer’s tax under this chapter for the taxable year in which such failure occurs shall be increased by an amount equal to the applicable portion of the credit under this section with respect to such building, increased by an amount of interest for the period—

(A) In generalTo the extent that the requirements of paragraph (2)(D) are not met, then the taxpayer’s tax under this chapter for the taxable year in which such failure occurs shall be increased by an amount equal to the applicable portion of the credit under this section with respect to such building, increased by an amount of interest for the period— (i) beginning with the due date for the filing of the return of tax imposed by chapter 1 for the 1st taxable year for which such credit was allowable, and (ii) ending with the due date for the taxable year in which such failure occurs, determined by using the underpayment rate and method under section 6621.

(B) Applicable portion For purposes of subparagraph (A), the term “applicable portion” means the aggregate decrease in the credits allowed to a taxpayer under section 38 for all prior taxable years which would have resulted if the eligible basis of the building were reduced by the amount of financing which does not meet requirements of paragraph (2)(D).

(C) Certain rules to apply Rules similar to the rules of subparagraphs (A) and (D) of subsection (j)(4) shall apply for purposes of this subsection.

Following the close of the 1st taxable year in the credit period with respect to any qualified low-income building, the taxpayer shall certify to the Secretary (at such time and in such form and in such manner as the Secretary prescribes)—
