§ 1.168(i)-8 — (i)-8 Dispositions Of Macrs Property

26 C.F.R. § 1.168(i)-8

View:

(a) Scope. This section provides rules applicable to dispositions of MACRS property (as defined in § 1.168(b)-1(a)(2)) or to depreciable property (as defined in § 1.168(b)-1(a)(1)) that would be MACRS property but for an election made by the taxpayer either to expense all or some of the property's cost under section 179, section 179A, section 179B, section 179C, section 179D, or section 1400I(a)(1), or any similar provision, or to amortize all or some of the property's cost under section 1400I(a)(2) or any similar provision. This section also applies to dispositions described in paragraph (d)(1) of this section of a portion of such property. Except as provided in § 1.168(i)-1(e)(3), this section does not apply to dispositions of assets included in a general asset account. For rules applicable to dispositions of assets included in a general asset account, see § 1.168(i)-1(e).

(b) Definitions. For purposes of this section—

(1) Building has the same meaning as that term is defined in § 1.48-1(e)(1).

(2) Disposition occurs when ownership of the asset is transferred or when the asset is permanently withdrawn from use either in the taxpayer's trade or business or in the production of income. A disposition includes the sale, exchange, retirement, physical abandonment, or destruction of an asset. A disposition also occurs when an asset is transferred to a supplies, scrap, or similar account, or when a portion of an asset is disposed of as described in paragraph (d)(1) of this section. If a structural component, or a portion thereof, of a building is disposed of in a disposition described in paragraph (d)(1) of this section, a disposition also includes the disposition of such structural component or such portion thereof.

(3) Mass assets is a mass or group of individual items of depreciable assets—

(i) That are not necessarily homogenous;

(ii) Each of which is minor in value relative to the total value of the mass or group;

(iii) Numerous in quantity;

(iv) Usually accounted for only on a total dollar or quantity basis;

(v) With respect to which separate identification is impracticable; and

(vi) Placed in service in the same taxable year.

(4) Portion of an asset is any part of an asset that is less than the entire asset as determined under paragraph (c)(4) of this section.

(5) Structural component has the same meaning as that term is defined in § 1.48-1(e)(2).

(6) Unadjusted depreciable basis of the multiple asset account or pool is the sum of the unadjusted depreciable bases (as defined in § 1.168(b)-1(a)(3)) of all assets included in the multiple asset account or pool.

(c) Special rules—(1) Manner of disposition. The manner of disposition (for example, normal retirement, abnormal retirement, ordinary retirement, or extraordinary retirement) is not taken into account in determining whether a disposition occurs or gain or loss is recognized.

(2) Disposition by transfer to a supplies account. If a taxpayer made an election under § 1.162-3(d) to treat the cost of any rotable spare part, temporary spare part, or standby emergency spare part (as defined in § 1.162-3(c)) as a capital expenditure subject to the allowance for depreciation, the taxpayer can dispose of the rotable, temporary, or standby emergency spare part by transferring it to a supplies account only if the taxpayer has obtained the consent of the Commissioner to revoke the § 1.162-3(d) election. If a taxpayer made an election under § 1.162-3T(d) to treat the cost of any material and supply (as defined in § 1.162-3T(c)(1)) as a capital expenditure subject to the allowance for depreciation, the taxpayer can dispose of the material and supply by transferring it to a supplies account only if the taxpayer has obtained the consent of the Commissioner to revoke the § 1.162-3T(d) election. See § 1.162-3(d)(3) for the procedures for revoking a § 1.162-3(d) or a § 1.162-3T(d) election.

(3) Leasehold improvements. This section also applies to—

(i) A lessor of leased property that made an improvement to that property for the lessee of the property, has a depreciable basis in the improvement, and disposes of the improvement, or disposes of a portion of the improvement under paragraph (d)(1) of this section, before or upon the termination of the lease with the lessee. See section 168(i)(8)(B); and

(ii) A lessee of leased property that made an improvement to that property, has a depreciable basis in the improvement, and disposes of the improvement, or disposes of a portion of the improvement under paragraph (d)(1) of this section, before or upon the termination of the lease.

(4) Determination of asset disposed of—(i) General rules. For purposes of applying this section, the facts and circumstances of each disposition are considered in determining what is the appropriate asset disposed of. The asset for disposition purposes may not consist of items placed in service by the taxpayer on different dates, without taking into account the applicable convention. For purposes of determining what is the appropriate asset disposed of, the unit of property determination under § 1.263(a)-3(e) or in published guidance in the Internal Revenue Bulletin (see § 601.601(d)(2) of this chapter) under section 263(a) and the distinct asset determination under § 1.1031(a)-3(a)(4) do not apply.

(ii) Special rules. In addition to the general rules in paragraph (c)(4)(i) of this section, the following rules apply for purposes of applying this section:

(A) Each building, including its structural components, is the asset, except as provided in § 1.1250-1(a)(2)(ii) or in paragraph (c)(4)(ii)(B) or (D) of this section.

(B) If a building has two or more condominium or cooperative units, each condominium or cooperative unit, including its structural components, is the asset, except as provided in § 1.1250-1(a)(2)(ii) or in paragraph (c)(4)(ii)(D) of this section.

(C) If a taxpayer properly includes an item in one of the asset classes 00.11 through 00.4 of Rev. Proc. 87-56 (1987-2 CB 674) (see § 601.601(d)(2) of this chapter) or properly classifies an item in one of the categories under section 168(e)(3), except for a category that includes buildings or structural components (for example, retail motor fuels outlet, qualified leasehold improvement property, qualified restaurant property, and qualified retail improvement property), each item is the asset provided paragraph (c)(4)(ii)(D) of this section does not apply to the item. For example, each desk is the asset, each computer is the asset, and each qualified smart electric meter is the asset.

(D) If the taxpayer places in service an improvement or addition to an asset after the taxpayer placed the asset in service, the improvement or addition and, if applicable, its structural components are a separate asset.

(d) Disposition of a portion of an asset—(1) In general. For purposes of applying this section, a disposition includes a disposition of a portion of an asset as a result of a casualty event described in section 165, a disposition of a portion of an asset for which gain, determined without regard to section 1245 or section 1250, is not recognized in whole or in part under section 1031 or section 1033, a transfer of a portion of an asset in a transaction described in section 168(i)(7)(B), or a sale of a portion of an asset, even if the taxpayer does not make the election under paragraph (d)(2)(i) of this section for that disposed portion. For other transactions, a disposition includes a disposition of a portion of an asset only if the taxpayer makes the election under paragraph (d)(2)(i) of this section for that disposed portion.

(2) Partial disposition election—(i) In general. A taxpayer may make an election under this paragraph (d)(2) to apply this section to a disposition of a portion of an asset. If the asset is properly included in one of the asset classes 00.11 through 00.4 of Rev. Proc. 87-56, a taxpayer may make an election under this paragraph (d)(2) to apply this section to a disposition of a portion of such asset only if the taxpayer classifies the replacement portion of the asset under the same asset class as the disposed portion of the asset.

(ii) Time and manner for making election—(A) Time for making election. Except as provided in paragraph (d)(2)(iii) or (iv) of this section, a taxpayer must make the election specified in paragraph (d)(2)(i) of this section by the due date, including extensions, of the original Federal tax return for the taxable year in which the portion of an asset is disposed of by the taxpayer.

(B) Manner of making election. Except as provided in paragraph (d)(2)(iii) or (iv) of this section, a taxpayer must make the election specified in paragraph (d)(2)(i) of this section by applying the provisions of this section for the taxable year in which the portion of an asset is disposed of by the taxpayer, by reporting the gain, loss, or other deduction on the taxpayer's timely filed, including extensions, original Federal tax return for that taxable year, and, if the asset is properly included in one of the asset classes 00.11 through 00.4 of Rev. Proc. 87-56, by classifying the replacement portion of such asset under the same asset class as the disposed portion of the asset in the taxable year in which the replacement portion is placed in service by the taxpayer. Except as provided in paragraph (d)(2)(iii) or (iv)(B) of this section or except as otherwise expressly provided by other guidance published in the Internal Revenue Bulletin (see § 601.601(d)(2) of this chapter), the election specified in paragraph (d)(2)(i) of this section may not be made through the filing of an application for change in accounting method.

(iii) Special rule for subsequent Internal Revenue Service adjustment. This paragraph (d)(2)(iii) applies when a taxpayer deducted the amount paid or incurred for the replacement of a portion of an asset as a repair under § 1.162-4, the taxpayer did not make the election specified in paragraph (d)(2)(i) of this section for the disposed portion of that asset within the time and in the manner under paragraph (d)(2)(ii) or (iv) of this section, and as a result of an examination of the taxpayer's Federal tax return, the Internal Revenue Service disallows the taxpayer's repair deduction for the amount paid or incurred for the replacement of the portion of that asset and instead capitalizes such amount under § 1.263(a)-2 or § 1.263(a)-3. If this paragraph (d)(2)(iii) applies, the taxpayer may make the election specified in paragraph (d)(2)(i) of this section for the disposition of the portion of the asset to which the Internal Revenue Service's adjustment pertains by filing an application for change in accounting method, provided the asset of which the disposed portion was a part is owned by the taxpayer at the beginning of the year of change (as defined for purposes of section 446(e)).

(iv) Special rules for 2012 or 2013 returns. If, under paragraph (j)(2) of this section, a taxpayer chooses to apply the provisions of this section to a taxable year beginning on or after January 1, 2012, and ending on or before September 19, 2013 (applicable taxable year), and the taxpayer did not make the election specified in paragraph (d)(2)(i) of this section on its timely filed original Federal tax return for the applicable taxable year, including extensions, the taxpayer must make the election specified in paragraph (d)(2)(i) of this section for the applicable taxable year by filing either—

(A) An amended Federal tax return for the applicable taxable year on or before 180 days from the due date including extensions of the taxpayer's Federal tax return for the applicable taxable year, notwithstanding that the taxpayer may not have extended the due date; or

(B) An application for change in accounting method with the taxpayer's timely filed original Federal tax return for the first or second taxable year succeeding the applicable taxable year.

(v) Revocation. A taxpayer may revoke the election specified in paragraph (d)(2)(i) of this section only by filing a request for a private letter ruling and obtaining the Commissioner's consent to revoke the election. The Commissioner may grant a request to revoke this election if the taxpayer acted reasonably and in good faith, and the revocation will not prejudice the interests of the Government. See generally § 301.9100-3 of this chapter. The election specified in paragraph (d)(2)(i) of this section may not be revoked through the filing of an application for change in accounting method.

(e) Gain or loss on dispositions. Solely for purposes of this paragraph (e), the term asset is an asset within the scope of this section or the portion of such asset that is disposed of in a disposition described in paragraph (d)(1) of this section. Except as provided by section 280B and § 1.280B-1, the following rules apply when an asset is disposed of during a taxable year:

(1) If an asset is disposed of by sale, exchange, or involuntary conversion, gain or loss must be recognized under the applicable provisions of the Internal Revenue Code.

(2) If an asset is disposed of by physical abandonment, loss must be recognized in the amount of the adjusted depreciable basis (as defined in § 1.168(b)-1(a)(4)) of the asset at the time of the abandonment, taking into account the applicable convention. However, if the abandoned asset is subject to nonrecourse indebtedness, paragraph (e)(1) of this section applies to the asset instead of this paragraph (e)(2). For a loss from physical abandonment to qualify for recognition under this paragraph (e)(2), the taxpayer must intend to discard the asset irrevocably so that the taxpayer will neither use the asset again nor retrieve it for sale, exchange, or other disposition.

(3) If an asset is disposed of other than by sale, exchange, involuntary conversion, physical abandonment, or conversion to personal use (as, for example, when the asset is transferred to a supplies or scrap account), gain is not recognized. Loss must be recognized in the amount of the excess of the adjusted depreciable basis of the asset at the time of the disposition, taking into account the applicable convention, over the asset's fair market value at the time of the disposition, taking into account the applicable convention.

(f) Basis of asset disposed of—(1) In general. The adjusted basis of an asset disposed of for computing gain or loss is its adjusted depreciable basis at the time of the asset's disposition, as determined under the applicable convention for the asset.

(2) Assets disposed of are in multiple asset accounts. (i) If the taxpayer accounts for the asset disposed of in a multiple asset account or pool and it is impracticable from the taxpayer's records to determine the unadjusted depreciable basis (as defined in § 1.168(b)-1(a)(3)) of the asset disposed of, the taxpayer may use any reasonable method that is consistently applied to all assets in the same multiple asset account or pool for purposes of determining the unadjusted depreciable basis of assets disposed of. Examples of a reasonable method include, but are not limited to, the following:

(A) If the replacement asset is a restoration (as defined in § 1.263(a)-3(k)), and is not a betterment (as defined in § 1.263(a)-3(j)) or an adaptation to a new or different use (as defined in § 1.263(a)-3(l)), discounting the cost of the replacement asset to its placed-in-service year cost using the Producer Price Index for Finished Goods or its successor, the Producer Price Index for Final Demand, or any other index designated by guidance in the Internal Revenue Bulletin (see § 601.601(d)(2) of this chapter) for purposes of this paragraph (f)(2);

(B) A pro rata allocation of the unadjusted depreciable basis of the multiple asset account or pool based on the replacement cost of the disposed asset and the replacement cost of all of the assets in the multiple asset account or pool; and

(C) A study allocating the cost of the asset to its individual components.

(ii) To determine the adjusted depreciable basis of an asset disposed of in a multiple asset account or pool, the depreciation allowable for the asset disposed of is computed by using the depreciation method, recovery period, and convention applicable to the multiple asset account or pool in which the asset disposed of was included and by including the additional first year depreciation deduction claimed for the asset disposed of.

(3) Disposition of a portion of an asset. (i) This paragraph (f)(3) applies only when a taxpayer disposes of a portion of an asset and paragraph (d)(1) of this section applies to that disposition. For computing gain or loss, the adjusted basis of the disposed portion of the asset is the adjusted depreciable basis of that disposed portion at the time of its disposition, as determined under the applicable convention for the asset. If it is impracticable from the taxpayer's records to determine the unadjusted depreciable basis (as defined in § 1.168(b)-1(a)(3)) of the disposed portion of the asset, the taxpayer may use any reasonable method for purposes of determining the unadjusted depreciable basis (as defined in § 1.168(b)-1(a)(3)) of the disposed portion of the asset. If a taxpayer disposes of more than one portion of the same asset and it is impracticable from the taxpayer's records to determine the unadjusted depreciable basis (as defined in § 1.168(b)-1(a)(3)) of the first disposed portion of the asset, the reasonable method used by the taxpayer must be consistently applied to all portions of the same asset for purposes of determining the unadjusted depreciable basis of each disposed portion of the asset. If the asset, a portion of which is disposed of, is in a multiple asset account or pool and it is impracticable from the taxpayer's records to determine the unadjusted depreciable basis (as defined in § 1.168(b)-1(a)(3)) of the disposed portion of the asset, the reasonable method used by the taxpayer must be consistently applied to all assets in the same multiple asset account or pool for purposes of determining the unadjusted depreciable basis of assets disposed of or any disposed portion of the assets. Examples of a reasonable method include, but are not limited to, the following:

(A) If the replacement portion is a restoration (as defined in § 1.263(a)-3(k)), and is not a betterment (as defined in § 1.263(a)-3(j)) or an adaptation to a new or different use (as defined in § 1.263(a)-3(l)), discounting the cost of the replacement portion of the asset to its placed-in-service year cost using the Producer Price Index for Finished Goods or its successor, the Producer Price Index for Final Demand, or any other index designated by guidance in the Internal Revenue Bulletin (see § 601.601(d)(2) of this chapter) for purposes of this paragraph (f)(3);

(B) A pro rata allocation of the unadjusted depreciable basis of the asset based on the replacement cost of the disposed portion of the asset and the replacement cost of the asset; and

(C) A study allocating the cost of the asset to its individual components.

(ii) To determine the adjusted depreciable basis of the disposed portion of the asset, the depreciation allowable for the disposed portion is computed by using the depreciation method, recovery period, and convention applicable to the asset in which the disposed portion was included and by including the portion of the additional first year depreciation deduction claimed for the asset that is attributable to the disposed portion.

(g) Identification of asset disposed of—(1) In general. Except as provided in paragraph (g)(2) or (3) of this section, a taxpayer must use the specific identification method of accounting to identify which asset is disposed of by the taxpayer. Under this method of accounting, the taxpayer can determine the particular taxable year in which the asset disposed of was placed in service by the taxpayer.

(2) Asset disposed of is in a multiple asset account. If a taxpayer accounts for the asset disposed of in a multiple asset account or pool and the total dispositions of assets with the same recovery period during the taxable year are readily determined from the taxpayer's records, but it is impracticable from the taxpayer's records to determine the particular taxable year in which the asset disposed of was placed in service by the taxpayer, the taxpayer must identify the asset disposed of by using—

(i) A first-in, first-out method of accounting if the unadjusted depreciable basis of the asset disposed of cannot be readily determined from the taxpayer's records. Under this method of accounting, the taxpayer identifies the multiple asset account or pool with the earliest placed-in-service year that has the same recovery period as the asset disposed of and that has assets at the beginning of the taxable year of the disposition, and the taxpayer treats the asset disposed of as being from that multiple asset account or pool;

(ii) A modified first-in, first-out method of accounting if the unadjusted depreciable basis of the asset disposed of can be readily determined from the taxpayer's records. Under this method of accounting, the taxpayer identifies the multiple asset account or pool with the earliest placed-in-service year that has the same recovery period as the asset disposed of and that has assets at the beginning of the taxable year of the disposition with the same unadjusted depreciable basis as the asset disposed of, and the taxpayer treats the asset disposed of as being from that multiple asset account or pool;

(iii) A mortality dispersion table if the asset disposed of is a mass asset. The mortality dispersion table must be based upon an acceptable sampling of the taxpayer's actual disposition experience for mass assets or other acceptable statistical or engineering techniques. To use a mortality dispersion table, the taxpayer must adopt recordkeeping practices consistent with the taxpayer's prior practices and consonant with good accounting and engineering practices; or

(iv) Any other method as the Secretary may designate by publication in the Federal Register or in the Internal Revenue Bulletin (see § 601.601(d)(2) of this chapter) on or after September 19, 2013. See paragraph (g)(4) of this section regarding the last-in, first-out method of accounting.

(3) Disposition of a portion of an asset. If a taxpayer disposes of a portion of an asset and paragraph (d)(1) of this section applies to that disposition, but it is impracticable from the taxpayer's records to determine the particular taxable year in which the asset was placed in service, the taxpayer must identify the asset by using any applicable method provided in paragraph (g)(2) of this section, after taking into account paragraph (g)(4) of this section.

(4) Last-in, first-out method of accounting. For purposes of this paragraph (g), a last-in, first-out method of accounting may not be used. Examples of a last-in, first-out method of accounting include the taxpayer identifying the multiple asset account or pool with the most recent placed-in-service year that has the same recovery period as the asset disposed of and that has assets at the beginning of the taxable year of the disposition, and the taxpayer treating the asset disposed of as being from that multiple asset account or pool, or the taxpayer treating the disposed portion of an asset as being from an asset with the most recent placed-in-service year that is the same as the asset of which the disposed portion is a part.

(h) Accounting for asset disposed of—(1) Depreciation ends. Depreciation ends for an asset at the time of the asset's disposition, as determined under the applicable convention for the asset. See § 1.167(a)-10(b). If the asset disposed of is in a single asset account initially or as a result of § 1.168(i)-8(h)(2)(i), § 1.168(i)-8(h)(3)(i), or general asset account treatment for the asset terminated under § 1.168(i)-1(c)(1)(ii)(A), (e)(3)(iii), (e)(3)(v), (e)(3)(vii), (g), or (h)(1), as applicable, the single asset account terminates at the time of the asset's disposition, as determined under the applicable convention for the asset. If a taxpayer disposes of a portion of an asset and paragraph (d)(1) of this section applies to that disposition, depreciation ends for that disposed portion of the asset at the time of the disposition of the disposed portion, as determined under the applicable convention for the asset.

(2) Asset disposed of in a multiple asset account or pool. If the taxpayer accounts for the asset disposed of in a multiple asset account or pool, then—

(i) As of the first day of the taxable year in which the disposition occurs, the asset disposed of is removed from the multiple asset account or pool and is placed into a single asset account. See § 1.168(i)-7(b);

(ii) The unadjusted depreciable basis of the multiple asset account or pool must be reduced by the unadjusted depreciable basis of the asset disposed of as of the first day of the taxable year in which the disposition occurs. See paragraph (f)(2)(i) of this section for determining the unadjusted depreciable basis of the asset disposed of;

(iii) The depreciation reserve of the multiple asset account or pool must be reduced by the greater of the depreciation allowed or allowable for the asset disposed of as of the end of the taxable year immediately preceding the year of disposition. The allowable depreciation is computed by using the depreciation method, recovery period, and convention applicable to the multiple asset account or pool in which the asset disposed of was included and by including the additional first year depreciation deduction claimed for the asset disposed of; and

(iv) In determining the adjusted depreciable basis of the asset disposed of at the time of disposition, taking into account the applicable convention, the depreciation allowable for the asset disposed of is computed by using the depreciation method, recovery period, and convention applicable to the multiple asset account or pool in which the asset disposed of was included and by including the additional first year depreciation deduction claimed for the asset disposed of.

(3) Disposition of a portion of an asset. This paragraph (h)(3) applies only when a taxpayer disposes of a portion of an asset and paragraph (d)(1) of this section applies to that disposition. In this case—

(i) As of the first day of the taxable year in which the disposition occurs, the disposed portion is placed into a single asset account. See § 1.168(i)-7(b);

(ii) The unadjusted depreciable basis of the asset must be reduced by the unadjusted depreciable basis of the disposed portion as of the first day of the taxable year in which the disposition occurs. See paragraph (f)(3)(i) of this section for determining the unadjusted depreciable basis of the disposed portion;

(iii) The depreciation reserve of the asset must be reduced by the greater of the depreciation allowed or allowable for the disposed portion as of the end of the taxable year immediately preceding the year of disposition. The allowable depreciation is computed by using the depreciation method, recovery period, and convention applicable to the asset in which the disposed portion was included and by including the portion of the additional first year depreciation deduction claimed for the asset that is attributable to the disposed portion; and

(iv) In determining the adjusted depreciable basis of the disposed portion at the time of disposition, taking into account the applicable convention, the depreciation allowable for the disposed portion is computed by using the depreciation method, recovery period, and convention applicable to the asset in which the disposed portion was included and by including the portion of the additional first year depreciation deduction claimed for the asset that is attributable to the disposed portion.

(i) Examples. The application of this section is illustrated by the following examples:

A owns an office building with four elevators. A replaces one of the elevators. The elevator is a structural component of the office building. In accordance with paragraph (c)(4)(ii)(A) of this section, the office building, including its structural components, is the asset for disposition purposes. A does not make the partial disposition election provided under paragraph (d)(2) of this section for the elevator. Thus, the retirement of the replaced elevator is not a disposition. As a result, depreciation continues for the cost of the building, including the cost of the retired elevator and the building's other structural components, and A does not recognize a loss for this retired elevator. If A must capitalize the amount paid for the replacement elevator pursuant to § 1.263(a)-3, the replacement elevator is a separate asset for disposition purposes pursuant to paragraph (c)(4)(ii)(D) of this section and for depreciation purposes pursuant to section 168(i)(6).

The facts are the same as in Example 1, except A accounts for each structural component of the office building as a separate asset in its fixed asset system. Although A treats each structural component as a separate asset in its records, the office building, including its structural components, is the asset for disposition purposes in accordance with paragraph (c)(4)(ii)(A) of this section. Accordingly, the result is the same as in Example 1.

The facts are the same as in Example 1, except A makes the partial disposition election provided under paragraph (d)(2) of this section for the elevator. Although the office building, including its structural components, is the asset for disposition purposes, the result of A making the partial disposition election for the elevator is that the retirement of the replaced elevator is a disposition. Thus, depreciation for the retired elevator ceases at the time of its retirement, taking into account the applicable convention, and A recognizes a loss upon this retirement. Further, A must capitalize the amount paid for the replacement elevator pursuant to § 1.263(a)-3(k)(1)(i), and the replacement elevator is a separate asset for disposition purposes pursuant to paragraph (c)(4)(ii)(D) of this section and for depreciation purposes pursuant to section 168(i)(6).

B, a calendar-year commercial airline company, owns several aircraft that are used in the commercial carrying of passengers and described in asset class 45.0 of Rev. Proc. 87-56. B replaces the existing engines on one of the aircraft with new engines. Assume each aircraft is a unit of property as determined under § 1.263(a)-3(e)(3) and each engine of an aircraft is a major component or substantial structural part of the aircraft as determined under § 1.263(a)-3(k)(6). Assume also that B treats each aircraft as the asset for disposition purposes in accordance with paragraph (c)(4) of this section. B makes the partial disposition election provided under paragraph (d)(2) of this section for the engines in the aircraft. Although the aircraft is the asset for disposition purposes, the result of B making the partial disposition election for the engines is that the retirement of the replaced engines is a disposition. Thus, depreciation for the retired engines ceases at the time of their retirement, taking into account the applicable convention, and B recognizes a loss upon this retirement. Further, B must capitalize the amount paid for the replacement engines pursuant to § 1.263(a)-3(k)(1)(i), and the replacement engines are a separate asset for disposition purposes pursuant to paragraph (c)(4)(ii)(D) of this section and for depreciation purposes pursuant to section 168(i)(6).

The facts are the same as in Example 4, except B does not make the partial disposition election provided under paragraph (d)(2) of this section for the engines. Thus, the retirement of the replaced engines on one of the aircraft is not a disposition. As a result, depreciation continues for the cost of the aircraft, including the cost of the retired engines, and B does not recognize a loss for these retired engines. If B must capitalize the amount paid for the replacement engines pursuant to § 1.263(a)-3, the replacement engines are a separate asset for disposition purposes pursuant to paragraph (c)(4)(ii)(D) of this section and for depreciation purposes pursuant to section 168(i)(6).

C, a corporation, owns several trucks that are used in its trade or business and described in asset class 00.241 of Rev. Proc. 87-56. C replaces the engine on one of the trucks with a new engine. Assume each truck is a unit of property as determined under § 1.263(a)-3(e)(3) and each engine is a major component or substantial structural part of the truck as determined under § 1.263(a)-3(k)(6). Because the trucks are described in asset class 00.241 of Rev. Proc. 87-56, C must treat each truck as the asset for disposition purposes. C does not make the partial disposition election provided under paragraph (d)(2) of this section for the engine. Thus, the retirement of the replaced engine on the truck is not a disposition. As a result, depreciation continues for the cost of the truck, including the cost of the retired engine, and C does not recognize a loss for this retired engine. If C must capitalize the amount paid for the replacement engine pursuant to § 1.263(a)-3, the replacement engine is a separate asset for disposition purposes pursuant to paragraph (c)(4)(ii)(D) of this section and for depreciation purposes pursuant to section 168(i)(6).

D owns a retail building. D replaces 60% of the roof of this building. In accordance with paragraph (c)(4)(ii)(A) of this section, the retail building, including its structural components, is the asset for disposition purposes. Assume D must capitalize the costs incurred for replacing 60% of the roof pursuant to § 1.263(a)-3(k)(1)(vi). D makes the partial disposition election provided under paragraph (d)(2) of this section for the 60% of the replaced roof. Thus, the retirement of 60% of the roof is a disposition. As a result, depreciation for 60% of the roof ceases at the time of its retirement, taking into account the applicable convention, and D recognizes a loss upon this retirement. Further, D must capitalize the amount paid for the 60% of the roof pursuant to § 1.263(a)-3(k)(1)(i) and (vi) and the replacement 60% of the roof is a separate asset for disposition purposes pursuant to paragraph (c)(4)(ii)(D) of this section and for depreciation purposes pursuant to section 168(i)(6).

(i) The facts are the same as in Example 7. Ten years after replacing 60% of the roof, D replaces 55% of the roof of the building. In accordance with paragraph (c)(4)(ii)(A) and (D) of this section, for disposition purposes, the retail building, including its structural components, except the replacement 60% of the roof, is an asset and the replacement 60% of the roof is a separate asset. Assume D must capitalize the costs incurred for replacing 55% of the roof pursuant to § 1.263(a)-3(k)(1)(vi). D makes the partial disposition election provided under paragraph (d)(2) of this section for the 55% of the replaced roof. Thus, the retirement of 55% of the roof is a disposition.

(ii) However, D cannot determine from its records whether the replaced 55% is part of the 60% of the roof replaced ten years ago or whether the replaced 55% includes part or all of the remaining 40% of the original roof. Pursuant to paragraph (g)(3) of this section, D identifies which asset it disposed of by using the first-in, first-out method of accounting. As a result, D disposed of the remaining 40% of the original roof and 25% of the 60% of the roof replaced ten years ago.

(iii) Thus, depreciation for the remaining 40% of the original roof ceases at the time of its retirement, taking into account the applicable convention, and D recognizes a loss upon this retirement. Further, depreciation for 25% of the 60% of the roof replaced ten years ago ceases at the time of its retirement, taking into account the applicable convention, and D recognizes a loss upon this retirement. Also, D must capitalize the amount paid for the 55% of the roof pursuant to § 1.263(a)-3(k)(1)(i) and (vi), and the replacement 55% of the roof is a separate asset for disposition purposes pursuant to paragraph (c)(4)(ii)(D) of this section and for depreciation purposes pursuant to section 168(i)(6).

(i) On July 1, 2011, E, a calendar-year taxpayer, purchased and placed in service an existing multi-story office building that costs $20,000,000. The cost of each structural component of the building was not separately stated. E accounts for the building and its structural components in its tax and financial accounting records as a single asset with a cost of $20,000,000. E depreciates the building as nonresidential real property and uses the optional depreciation table that corresponds with the general depreciation system, the straight-line method, a 39-year recovery period, and the mid-month convention. As of January 1, 2014, the depreciation reserve for the building is $1,261,000.

(ii) On June 30, 2014, E replaces one of the two elevators in the office building. E did not dispose of any other structural components of this building in 2014 and prior years. E makes the partial disposition election provided under paragraph (d)(2) of this section for this elevator. Although the office building, including its structural components, is the asset for disposition purposes, the result of E making the partial disposition election for the elevator is that the retirement of the replaced elevator is a disposition. Assume the replacement elevator is a restoration under § 1.263(a)-3(k), and not a betterment under § 1.263(a)-3(j) or an adaptation to a new or different use under § 1.263(a)-3(l). Because E cannot identify the cost of the elevator from its records and the replacement elevator is a restoration under § 1.263(a)-3(k), E determines the cost of the disposed elevator by discounting the cost of the replacement elevator to its placed-in-service year cost using the Producer Price Index for Final Demand. Using this reasonable method, E determines the cost of the retired elevator by discounting the cost of the replacement elevator to its cost in 2011 (the placed-in-service year) using the Producer Price Index for Final Demand, resulting in $150,000 of the $20,000,000 purchase price for the building to be the cost of the retired elevator. Using the optional depreciation table that corresponds with the general depreciation system, the straight-line method, a 39-year recovery period, and the mid-month convention, the depreciation allowed or allowable for the retired elevator as of December 31, 2013, is $9,458.

(iii) For E's 2014 Federal tax return, the loss for the retired elevator is determined as follows. The depreciation allowed or allowable for 2014 for the retired elevator is $1,763 ((unadjusted depreciable basis of $150,000 × depreciation rate of 2.564% for 2014) × 5.5/12 months). Thus, the adjusted depreciable basis of the retired elevator is $138,779 (the adjusted depreciable basis of $140,542 removed from the building cost less the depreciation allowed or allowable of $1,763 for 2014). As a result, E recognizes a loss of $138,779 for the retired elevator in 2014.

(iv) For E's 2014 Federal tax return, the depreciation allowance for the building is computed as follows. As of January 1, 2014, the unadjusted depreciable basis of the building is reduced from $20,000,000 to $19,850,000 ($20,000,000 less the unadjusted depreciable basis of $150,000 for the retired elevator), and the depreciation reserve of the building is reduced from $1,261,000 to $1,251,542 ($1,261,000 less the depreciation allowed or allowable of $9,458 for the retired elevator as of December 31, 2013). Consequently, the depreciation allowance for the building for 2014 is $508,954 ($19,850,000 × depreciation rate of 2.564% for 2014).

(v) E also must capitalize the amount paid for the replacement elevator pursuant to § 1.263(a)-3(k)(1). The replacement elevator is a separate asset for disposition purposes pursuant to paragraph (c)(4)(ii)(D) of this section and for depreciation purposes pursuant to section 168(i)(6).

(i) Since 2005, F, a calendar year taxpayer, has accounted for items of MACRS property that are mass assets in pools. Each pool includes only the mass assets that have the same depreciation method, recovery period, and convention, and are placed in service by F in the same taxable year. None of the pools are general asset accounts under section 168(i)(4) and the regulations under section 168(i)(4). F identifies any dispositions of these mass assets by specific identification.

(ii) During 2014, F sells 10 items of mass assets with a 5-year recovery period each for $100. Under the specific identification method, F identifies these mass assets as being from the pool established by F in 2012 for mass assets with a 5-year recovery period. Assume F depreciates this pool using the optional depreciation table that corresponds with the general depreciation system, the 200-percent declining balance method, a 5-year recovery period, and the half-year convention. F elected not to deduct the additional first year depreciation provided by section 168(k) for 5-year property placed in service during 2012. As of January 1, 2014, this pool contains 100 similar items of mass assets with a total cost of $25,000 and a total depreciation reserve of $13,000. Because all the items of mass assets in the pool are similar, F allocates the cost and depreciation allowed or allowable for the pool ratably among each item in the pool. This allocation is a reasonable method because all the items of mass assets in the pool are similar. Using this reasonable method, F allocates a cost of $250 ($25,000 × (1/100)) to each disposed of mass asset and depreciation allowed or allowable of $130 ($13,000 × (1/100)) to each disposed of mass asset. The depreciation allowed or allowable in 2014 for each disposed of mass asset is $24 (($250 × 19.2%)/2). As a result, the adjusted depreciable basis of each disposed of mass asset under section 1011 is $96 ($250 − $130 − $24). Thus, F recognizes a gain of $4 for each disposed of mass asset in 2014, which is subject to section 1245.

(iii) Further, as of January 1, 2014, the unadjusted depreciable basis of the 2012 pool of mass assets with a 5-year recovery period is reduced from $25,000 to $22,500 ($25,000 less the unadjusted depreciable basis of $2,500 for the 10 disposed of items), and the depreciation reserve of this 2012 pool is reduced from $13,000 to $11,700 ($13,000 less the depreciation allowed or allowable of $1,300 for the 10 disposed of items as of December 31, 2013). Consequently, as of January 1, 2014, the 2012 pool of mass assets with a 5-year recovery period has 90 items with a total cost of $22,500 and a depreciation reserve of $11,700. Thus, the depreciation allowance for this pool for 2014 is $4,320 ($22,500 × 19.2%).

(i) The facts are the same as in Example 10. Because of changes in F's recordkeeping in 2015, it is impracticable for F to continue to identify disposed of mass assets using specific identification and to determine the unadjusted depreciable basis of the disposed of mass assets. As a result, F files a Form 3115, Application for Change in Accounting Method, to change to a first-in, first-out method beginning with the taxable year beginning on January 1, 2015, on a modified cut-off basis. See § 1.446-1(e)(2)(ii)(d)(2)(vii). Under the first-in, first-out method, the mass assets disposed of in a taxable year are deemed to be from the pool with the earliest placed-in-service year that has assets as of the beginning of the taxable year of the disposition with the same recovery period as the asset disposed of. The Commissioner of Internal Revenue consents to this change in method of accounting.

(ii) During 2015, F sells 20 items of mass assets with a 5-year recovery period each for $50. As of January 1, 2015, the 2008 pool is the pool with the earliest placed-in-service year for mass assets with a 5-year recovery period, and this pool contains 25 items of mass assets with a total cost of $10,000 and a total depreciation reserve of $10,000. Thus, F allocates a cost of $400 ($10,000 × (1/25)) to each disposed of mass asset and depreciation allowed or allowable of $400 to each disposed of mass asset. As a result, the adjusted depreciable basis of each disposed of mass asset is $0. Thus, F recognizes a gain of $50 for each disposed of mass asset in 2015, which is subject to section 1245.

(iii) Further, as of January 1, 2015, the unadjusted depreciable basis of the 2008 pool of mass assets with a 5-year recovery period is reduced from $10,000 to $2,000 ($10,000 less the unadjusted depreciable basis of $8,000 for the 20 disposed of items ($400 × 20)), and the depreciation reserve of this 2008 pool is reduced from $10,000 to $2,000 ($10,000 less the depreciation allowed or allowable of $8,000 for the 20 disposed of items as of December 31, 2014). Consequently, as of January 1, 2015, the 2008 pool of mass assets with a 5-year recovery period has 5 items with a total cost of $2,000 and a depreciation reserve of $2,000.

(j) Effective/applicability dates—(1) In general. Except as provided in paragraph (j)(5) of this section, this section applies to taxable years beginning on or after January 1, 2014.

(2) Early application of this section. A taxpayer may choose to apply the provisions of this section to taxable years beginning on or after January 1, 2012.

(3) Early application of regulation project REG-110732-13. A taxpayer may rely on the provisions of this section in regulation project REG-110732-13 (2013-43 IRB 404) (see § 601.601(d)(2) of this chapter) for taxable years beginning on or after January 1, 2012. However, a taxpayer may not rely on the provisions of this section in regulation project REG-110732-13 for taxable years beginning on or after January 1, 2014.

(4) Optional application of TD 9564. A taxpayer may choose to apply § 1.168(i)-8T as contained in 26 CFR part 1 edition revised as of April 1, 2014, to taxable years beginning on or after January 1, 2012. However, a taxpayer may not apply § 1.168(i)-8T as contained in 26 CFR part 1 edition revised as of April 1, 2014, to taxable years beginning on or after January 1, 2014.

(5) Application of paragraph (c)(4)(i). The language “and the distinct asset determination under § 1.1031(a)-3(a)(4) do not apply.” in the last sentence of paragraph (c)(4)(i) of this section applies on or after December 2, 2020. Paragraph (c)(4)(i) of this section as contained in 26 CFR part 1 edition revised as of April 1, 2020, applies before December 2, 2020.

(6) Change in method of accounting. A change to comply with this section for depreciable assets placed in service in a taxable year ending on or after December 30, 2003, is a change in method of accounting to which the provisions of section 446(e) and the regulations under section 446(e) apply. A taxpayer also may treat a change to comply with this section for depreciable assets placed in service in a taxable year ending before December 30, 2003, as a change in method of accounting to which the provisions of section 446(e) and the regulations under section 446(e) apply. This paragraph (j)(5) does not apply to a change to comply with paragraph (d)(2) of this section, except as provided in paragraph (d)(2)(iii) or (iv)(B) of this section or otherwise provided by other guidance published in the Internal Revenue Bulletin (see § 601.601(d)(2) of this chapter).
