For purposes of paragraph (1)—

(A) In general The term “rehabilitation expenditures” means amounts chargeable to capital account and incurred for property (or additions or improvements to property) of a character subject to the allowance for depreciation in connection with the rehabilitation of a building.

(B) Cost of acquisition, etc., not included Such term does not include the cost of acquiring any building (or interest therein) or any amount not permitted to be taken into account under paragraph (3) or (4) of subsection (d).

(A) In general Paragraph (1) shall apply to rehabilitation expenditures with respect to any building only if— (i) the expenditures are allocable to 1 or more low-income units or substantially benefit such units, and (ii) the amount of such expenditures during any 24-month period meets the requirements of whichever of the following subclauses requires the greater amount of such expenditures: (I) The requirement of this subclause is met if such amount is not less than 20 percent of the adjusted basis of the building (determined as of the 1st day of such period and without regard to paragraphs (2) and (3) of section 1016(a)). (II) The requirement of this subclause is met if the qualified basis attributable to such amount, when divided by the number of low-income units in the building, is $6,000 or more.

(B) Exception from 10 percent rehabilitation In the case of a building acquired by the taxpayer from a governmental unit, at the election of the taxpayer, subparagraph (A)(ii)(I) shall not apply and the credit under this section for such rehabilitation expenditures shall be determined using the percentage applicable under subsection (b)(2)(B)(ii).

(C) Date of determination The determination under subparagraph (A) shall be made as of the close of the 1st taxable year in the credit period with respect to such expenditures.

(D) Inflation adjustment In the case of any expenditures which are treated under paragraph (4) as placed in service during any calendar year after 2009, the $6,000 amount in subparagraph (A)(ii)(II) shall be increased by an amount equal to— (i) such dollar amount, multiplied by (ii) the cost-of-living adjustment determined under section 1(f)(3) for such calendar year by substituting “calendar year 2008” for “calendar year 2016” in subparagraph (A)(ii) thereof. Any increase under the preceding sentence which is not a multiple of $100 shall be rounded to the nearest multiple of $100.

For purposes of applying this section with respect to expenditures which are treated as a separate building by reason of this subsection—

(A) such expenditures shall be treated as placed in service at the close of the 24-month period referred to in paragraph (3)(A), and

(B) the applicable fraction under subsection (c)(1) shall be the applicable fraction for the building (without regard to paragraph (1)) with respect to which the expenditures were incurred.
