(a) In general—(1) Definition for purposes of section 1250(b)(1). Except as otherwise provided in paragraph (e) of this section, for purposes of section 1250(b)(1), the term additional depreciation means:

(i) In the case of property which at the time of disposition has a holding period under section 1223 of not more than 1 year, the depreciation adjustments (as defined in paragraph (d) of this section) in respect of such property for periods after December 31, 1963, and

(ii) In the case of property which at the time of disposition has a holding period under section 1223 of more than 1 year, the depreciation adjustments in excess of straight line for periods after December 31, 1963, computed under paragraph (b)(1) of this section.

(2) Definition for purposes of section 1250(b)(4). Except as otherwise provided in paragraph (e) of this section, for purposes of section 1250(b)(4), the term additional depreciation means:

(i) In the case of property with respect to which a deduction under section 167(k) (relating to depreciation of expenditures to rehabilitate low-income rental housing) was allowed, which at the time of disposition has a holding period under section 1223 of not more than 1 year from the time the rehabilitation expenditures were incurred, the depreciation adjustments (as defined in paragraph (d) of this section) in respect of the property, and

(ii) In the case of property with respect to which a deduction under section 167(k) (relating to depreciation of expenditures to rehabilitate low-income rental housing) was allowed, which at the time of disposition has a holding period under section 1223 of more than 1 year from the time the rehabilitation expenditures were incurred, the depreciation adjustments in excess of straight line for the property, computed under paragraph (b)(2) of this section.

For purposes of this subparagraph, all rehabilitation expenditures which are incurred in connection with the rehabilitation of an element of section 1250 property shall be considered incurred on the date the last such expenditure is considered incurred under the accrual method of accounting, regardless of the method of accounting used by the taxpayer with regard to other items of income and expense. If the property consists of two or more elements (for example, if the property is placed in service at different times), then each element shall be treated as if it were a separate property and the expenditures attributable to each such element shall be considered incurred on the date the last such expenditure is considered incurred.

(3) Allocation to certain periods. With respect to a taxable year beginning in 1963 and ending in 1964, or beginning in 1969 and ending in 1970, the amount of depreciation adjustments or of depreciation adjustments in excess of straight line (as the case may be) shall be ascertained by applying the principles of paragraph (c)(3) of §1.167(a)-8 (relating to determination of adjusted basis of retired asset), and the amount determined in such manner shall be allocated on a daily basis in order to determine the portion thereof which is attributable to a period after December 31, 1963, or after December 31, 1969, as the case may be.

(b) Computation of depreciation adjustments in excess of straight line—(1) General rule. For purposes of paragraph (a)(1) of this section, depreciation adjustments in excess of straight line shall be, in the case of any property, the excess of (i) the sum of the depreciation adjustments (as defined in paragraph (d) of this section) in respect of the property attributable to periods after December 31, 1963, over (ii) the sum such adjustments would have been for such periods if such adjustments had been determined for the entire period the property was held under the straight line method of depreciation (or, if applicable, under the lease-renewal-period provision in paragraph (c) of this section). Depreciation in excess of straight line may arise, for example, if the declining balance method, the sum of the years-digits method, or the units of production method is used, or for another example, if the cost of a leasehold improvement or of a leasehold is depreciated over a period which does not take into account certain renewal periods referred to in paragraph (c) of this section. For computations of depreciation adjustments in excess of straight line (or a deficit therein) both on an annual basis and on the basis of the entire period the property was held, see subparagraph (6) of this paragraph.

(2) Depreciation under section 167(k). For purposes of paragraph (a)(2) of this section, depreciation adjustments in excess of straight line shall be, in the case of any property with respect to which a deduction was allowed under section 167(k) (relating to depreciation of expenditures to rehabilitate low-income rental housing), the excess of (i) the sum of the depreciation adjustments (as defined in paragraph (d) of this section) allowed in respect of the property, over (ii) the sum such adjustments would have been if such adjustments had been determined for the entire period the property was held under the straight line method of depreciation permitted by section 167(b)(1).

(3) General rule for computing useful life and salvage value. For purposes of computing under subparagraph (1)(ii) of this paragraph the sum of the depreciation adjustments would have been under the straight line method, if a useful life (or salvage value) was used in determining the amount allowed as a depreciation adjustment for any taxable year, such life (or value) shall be used in determining the amount such depreciation adjustment would have been for such taxable year under the straight line method. If, however, for any taxable year a method of depreciation was used as to which a useful life was not taken into account such as, for example, the units of production method, or as to which salvage value was not taken into account in determining the annual allowances, such as, for example, the declining balance method or the amortization of a leasehold improvement over the term of a lease, then, for the purpose of determining the amount such depreciation adjustment would have been under the straight line method for such taxable year:

(i) There shall be used the useful life (or salvage value) which would have been proper if depreciation had actually been determined under the straight line method throughout the period the property was held, and

(ii) Such useful life (or such salvage value) shall be determined by taking into account for each taxable year the same facts and circumstances as would have been taken into account if the taxpayer had used such method throughout the period the property was held.

(4) Special rule for computing useful life and salvage value (section 167(k)). For purposes of computing under subparagraph (2)(ii) of this paragraph the sum the depreciation adjustments would have been under the straight line method, the useful life and salvage value permitted under section 167(k) shall not apply, the useful life of the property shall be determined under paragraph (b) of §1.167(a)-1 (or, if applicable, under the lease-renewal-period provision of paragraph (c) of this section), and the salvage value of the property shall be determined under paragraph (c) of §1.167(a)-1. Such useful life or salvage value shall be determined by taking into account for each taxable year the same facts and circumstances as would have been taken into account if the taxpayer had used the straight line method permitted under section 167(b)(1) throughout the period the property was held.

(5) Property held before January 1, 1964. In the case of property held before January 1, 1964:

(i) For purposes of computing under subparagraph (1)(ii) of this paragraph the sum the depreciation adjustments would have been under the straight line method, the adjusted basis of the property on such date shall be the amount such adjusted basis would have been if depreciation deductions allowed or allowable before such date had been determined under the straight line method computed in accordance with subparagraph (3) of this paragraph, and

(ii) The depreciation adjustments in excess of straight line in respect of the property computed under subparagraph (1) of this paragraph, but without regard to this subdivision, shall be reduced by the amount of depreciation adjustments less than straight line for periods before January 1, 1964, that is, by the excess (if any) of the sum the depreciation adjustments would have been for periods before January 1, 1964, under the straight line method, over the sum of the depreciation adjustments attributable to periods before such date.

(6) Determination of additional depreciation in certain cases. If an item of section 1250 property is subject to two (or more) applicable percentages, a separate computation of additional depreciation shall be made for the portion of the taxpayer's holding period subject to each such percentage. That is, a separate computation shall be made to determine the excess of (i) the depreciation adjustments (as defined in paragraph (d) of this section) for each such portion of the taxpayer's holding period after December 31, 1963, over (ii) the amount such adjustments would have been for each such portion if such adjustments were determined under the straight line method of depreciation (or, if applicable, under the lease-renewal-period provision in paragraph (c) of this section). Thus, for example, in the case of an item of section 1250 property acquired on January 1, 1968, and disposed of on January 1, 1973, if the applicable percentage for the period before January 1, 1970, were determined under paragraph (d)(2) of §1.1250-1 and the applicable percentage for the period after December 31, 1969, were determined under paragraph (d)(1)(i)(e) of §1.1250-1, the additional depreciation would be computed separately for the period before January 1, 1970, and for the period after December 31, 1969. If the additional depreciation attributable to any such portion of the taxpayer's holding period is a deficit (that is, if the depreciation adjustments for that portion are less than the amount such adjustments would have been for that portion if depreciation adjustments were determined for the entire period the property was held under the straight line method of depreciation, or, if applicable, under the lease-renewal-period provision in paragraph (c) of this section), then such deficit will be applied to reduce the additional depreciation for other portion (or portions) of the taxpayer's holding period. (See examples (4) and (5) of subparagraph (7) of this paragraph.)

(7) Examples. The provisions of this paragraph may be illustrated by the following examples:

(c) Property held by lessee—(1) Amount depreciation would have been. For purposes of paragraph (b) of this section, in case of a leasehold which is section 1250 property, in determining the amount the depreciation adjustments would have been under the straight line method in respect of any building or other improvement (which is section 1250 property) erected or made on the leased property, or in respect of any cost of acquiring the lease, the lease period shall be treated as including all renewal periods. See section 1250(b)(2). For determination of the extent to which a leasehold is section 1250 property, see paragraph (e)(3) of §1.1250-1.

(2) Renewal period.

(i) For purposes of this paragraph, the term renewal period means any period for which the lease may be renewed, extended, or continued pursuant to an option or options exercisable by the lessee (whether or not specifically provided for in the lease) except that the inclusion of one or more renewal periods shall not extend the period taken into account by more than two-thirds of the period on the basis of which the depreciation adjustments were allowed.

(ii) In respect of the cost of any building erected (or other improvement made) on the leased property by the lessee, or in respect of the portion of the cost of acquiring a leasehold which is attributable to an existing building (or other improvement) on the leasehold at the time the lessee acquires the leasehold, the inclusion of one or more renewal periods shall not extend the period taken into account to a period which exceeds the useful life remaining, at the time the leasehold is disposed of, of such building (or such other improvement). Determinations under this subdivision shall be made without regard to the proper period under section 167 or 178 for depreciating or amortizing a leasehold acquisition cost or improvement.

(iii) The provisions of this subparagraph may be illustrated by the following example:

(d) Depreciation adjustments—(1) General. For purposes of this section, the term depreciation adjustments means, in respect of any property, all adjustments reflected in the adjusted basis of such property on account of deductions described in subparagraph (2) of this paragraph allowed or allowable (whether in respect of the same or other property) to the taxpayer or to any other person. For cases where the taxpayer can establish that the amount allowed for any period was less than the amount allowable, see subparagraph (4) of this paragraph. For determination of adjusted basis of property in a multiple asset account, see paragraph (c)(3) of §1.167(a)-8. The term depreciation adjustments as used in this section does not have the same meaning as the term adjustments reflected in the adjusted basis as defined in paragraph (a)(2) of §1.1245-2.

(2) Deductions. The deductions described in this subparagraph are allowances (and amounts treated as allowances) for depreciation or amortization (other than amortization under section 168, 169 (as enacted by section 704(a), Tax Reform Act of 1969 (83 Stat. 667)), or 185). Thus, for example, such deductions include a reasonable allowance for exhaustion, wear, and tear (including a reasonable allowance for obsolesence) under section 167, the periodic deductions referred to in §1.162-11 in respect of a specified sum paid for the acquisition of a leasehold and in respect of the cost to a lessee of improvements on property of which he is the lessee. However, such deductions do not include deductions for the periodic payment of rent.

(3) Depreciation of other taxpayers or in respect of other property.

(i) The depreciation adjustments (reflected in the adjusted basis) referred to in subparagraph (1) of this paragraph (a) are not limited to adjustments with respect to the property disposed of, nor to those allowed or allowable to the taxpayer disposing of such property, and (b) except as provided in subparagraph (4) of this paragraph, are taken into account, whether allowed or allowable in respect of the same or other property and whether to the taxpayer or to any other person. For manner of determining the amount of additional depreciation after certain dispositions, see paragraph (e) of this section.

(ii) The provisions of this subparagraph may be illustrated by the following example:

(4) Depreciation allowed or allowable.

(i) For purposes of subparagraph (1) of this paragraph, generally all deductions (described in subparagraph (2) of this paragraph) allowed or allowable shall be taken into account. See section 1016(a)(2) and the regulations thereunder for the meaning of allowed and allowable. However, if a taxpayer can establish by adequate records or other sufficient evidence that the amount allowed for any period was less than the amount allowable for such period, the amount to be taken into account for such period shall be the amount allowed. The preceding sentence shall not apply for purposes of computing under paragraph (b)(1)(ii) of this section the amount such deductions would have been under the straight line method.

(ii) The provisions of subdivision (i) of this subparagraph may be illustrated by the following example:

(5) Retired or demolished property. Depreciation adjustments referred to in subparagraph (1) of this paragraph generally do not include adjustments in respect of retired or demolished portions of an item of section 1250 property. If a retired or demolished portion is replaced in a disposition described in section 1250(d)(4)(A) (relating to like kind exchanges and involuntary conversions), see paragraph (d)(7) of §1.1250-3.

(6) Exempt organization. In respect of property disposed of by an organization which is or was exempt from income taxes (within the meaning of section 501(a), the depreciation adjustments (reflected in the adjusted basis) referred to in subparagraph (1) of this paragraph shall include only adjustments allowed or allowable (i) in computing unrelated business taxable income (as defined in section 512(a)), or (ii) in computing taxable income of the organization for a period during which it was not exempt or, by reason of the application of section 502, 503, or 504, was denied its exemption.

(e) Additional depreciation immediately after certain acquisitions—(1) Zero. If on the date a person acquires property his basis for the property is determined solely (i) by reference to its cost (within the meaning of section 1012), (ii) by reason of the application of section 301(d) (relating to basis of property received in corporate distribution) or section 334(a) (relating to basis of property received in a liquidation in which gain or loss is recognized), or (iii) under the rules of section 334 (b)(2) or (c) (relating to basis of property received in certain corporate liquidations), then on such date the additional depreciation for the property is zero.

(2) Transactions referred to in section 1250(d). In the case of property acquired in a disposition described in section 1250(d) (relating to exceptions and limitations to application of section 1250), additional depreciation shall be computed in accordance with the rules prescribed in §1.1250-3.

(f) Records to be kept and information to be filed—(1) Records to be kept. In any case in which it is necessary to determine the additional depreciation of an item of section 1250 property, the taxpayer shall have available permanent records of all the facts necessary to determine with reasonable accuracy the amount of such additional depreciation, including the following:

(i) The date, and the manner in which, the property was acquired,

(ii) The taxpayer's basis on the date the property was acquired and the manner in which the basis was determined,

(iii) The amount and date of all adjustments to the basis of the property allowed or allowable to the taxpayer for depreciation adjustments referred to in paragraph (d)(1) of this section and the amount and date of any other adjustments by the taxpayer to the basis of the property, and

(iv) In the case of section 1250 property which has an adjusted basis reflecting depreciation adjustments referred to in paragraph (d)(1) of this section taken by the taxpayer with respect to other property, or by another taxpayer with respect to the same or other property, the information described in subdivisions (i), (ii), and (iii) of this subparagraph with respect to such other property or such other taxpayer.

(2) Information to be filed. If a taxpayer acquires in a transaction (other than a like kind exchange or involuntary conversion described in section 1250(d)(4)) section 1250 property which has a basis reflecting depreciation adjustments referred to in paragraph (d)(1) of this section allowed or allowable to another taxpayer, then the taxpayer shall file with its income tax return or information return for the taxable year in which the property is acquired a statement showing all information described in subparagraph (1) of this paragraph. See section 6012 (relating to persons required to make returns of income) and part III of subchapter A of chapter 61 of the Code (relating to information returns).
