(d) Transitional rule

No portion of the unused business credit for any taxable year which is attributable to a credit specified in section 38(b) or any portion thereof may be carried back to any taxable year before the first taxable year for which such specified credit or such portion is allowable (without regard to subsection (a)).

In the case of a project with respect to which the taxpayer elects the requirements of subparagraph (A) or (B) of paragraph (1), if the income of the occupants of the unit increases above 140 percent of the income limitation applicable under paragraph (1), clause (i) shall cease to apply to such unit if any residential rental unit in the building (of a size comparable to, or smaller than, such unit) is occupied by a new resident whose income exceeds such income limitation.

(iii) Rental of next available unit in case of average income test

In the case of a project with respect to which the taxpayer elects the requirements of subparagraph (C) of paragraph (1), if the income of the occupants of the unit increases above 140 percent of the greater of—

(I) 60 percent of area median gross income, or

(II) the imputed income limitation designated with respect to the unit under paragraph (1)(C)(ii)(I),


 clause (i) shall cease to apply to any such unit if any residential rental unit in the building (of a size comparable to, or smaller than, such unit) is occupied by a new resident whose income exceeds the limitation described in clause (v).

(E) Units where Federal rental assistance is reduced as tenant's income increases

If the gross rent with respect to a residential unit exceeds the limitation under subparagraph (A) by reason of the fact that the income of the occupants thereof exceeds the income limitation applicable under paragraph (1), such unit shall, nevertheless, be treated as a rent-restricted unit for purposes of paragraph (1) if—

(i) a Federal rental assistance payment described in subparagraph (B)(i) is made with respect to such unit or its occupants, and

(B) Buildings which rely on later buildings for qualification

(i) In general

In determining whether a building (hereinafter in this subparagraph referred to as the "prior building") is a qualified low-income building, the taxpayer may take into account 1 or more additional buildings placed in service during the 12-month period described in subparagraph (A) with respect to the prior building only if the taxpayer elects to apply clause (ii) with respect to each additional building taken into account.

(iii) Date prior building is treated as placed in service

For purposes of determining the credit period and the compliance period for the prior building, the prior building shall be treated for purposes of this section as placed in service on the most recent date any additional building elected by the taxpayer (with respect to such prior building) was placed in service.

(C) Special rule

A building—

(i) other than the 1st building placed in service as part of a project, and

(ii) other than a building which is placed in service during the 12-month period described in subparagraph (A) with respect to a prior building which becomes a qualified low-income building,

(6) Special rule where de minimis equity contribution

Property shall not be treated as failing to be residential rental property for purposes of this section merely because the occupant of a residential unit in the project pays (on a voluntary basis) to the lessor a de minimis amount to be held toward the purchase by such occupant of a residential unit in such project if—

(A) all amounts so paid are refunded to the occupant on the cessation of his occupancy of a unit in the project, and

(B) the purchase of the unit is not permitted until after the close of the compliance period with respect to the building in which the unit is located.


Any amount paid to the lessor as described in the preceding sentence shall be included in gross rent under paragraph (2) for purposes of determining whether the unit is rent-restricted.

(7) Scattered site projects

Buildings which would (but for their lack of proximity) be treated as a project for purposes of this section shall be so treated if all of the dwelling units in each of the buildings are rent-restricted (within the meaning of paragraph (2)) residential rental units.

Any such recapture shall be payable to the Secretary of the Treasury for deposit in the general fund of the Treasury and may be enforced by means of liens or such other methods as the Secretary of the Treasury determines appropriate.

"(d) Return of Unused Grant Funds.—Any grant funds not used to make subawards under this section before January 1, 2011, shall be returned to the Secretary of the Treasury on such date.

(b) Limitations and adjustments

(1) Phaseout of credit

The amount of the credit determined under subsection (a) shall be reduced by an amount which bears the same ratio to the amount of the credit (determined without regard to this paragraph) as—

(2) Reduction as oil and gas prices increase

(A) In general

The $3 and 50 cents amounts under paragraph (1) shall each be reduced (but not below zero) by an amount which bears the same ratio to such amount (determined without regard to this paragraph) as—

(i) the excess (if any) of the applicable reference price over $15 ($1.67 for qualified natural gas production), bears to

(ii) $3 ($0.33 for qualified natural gas production).


The applicable reference price for a taxable year is the reference price of the calendar year preceding the calendar year in which the taxable year begins.

(B) Inflation adjustment

In the case of any taxable year beginning in a calendar year after 2005, each of the dollar amounts contained in subparagraph (A) shall be increased to an amount equal to such dollar amount multiplied by the inflation adjustment factor for such calendar year (determined under section 43(b)(3)(B) by substituting "2004" for "1990").

(C) Reference price

For purposes of this paragraph, the term "reference price" means, with respect to any calendar year—

(i) in the case of qualified crude oil production, the reference price determined under section 45K(d)(2)(C), and

(B) Proportionate reductions

(i) Short taxable years

In the case of a short taxable year, the limitations under this paragraph shall be proportionately reduced to reflect the ratio which the number of days in such taxable year bears to 365.

(ii) Wells not in production entire year

In the case of a well which is not capable of production during each day of a taxable year, the limitations under this paragraph applicable to the well shall be proportionately reduced to reflect the ratio which the number of days of production bears to the total number of days in the taxable year.
