  1. (a)Overview. This section provides rules for applying section 263(a) to amounts paid to improve tangible property. Paragraph (b) of this section provides definitions. Paragraph (c) of this section provides rules for coordinating this section with other provisions of the Internal Revenue Code (Code). Paragraph (d) of this section provides the requirement to capitalize amounts paid to improve tangible property and provides the general rules for determining whether a unit of property is improved. Paragraph (e) of this section provides the rules for determining the appropriate unit of property. Paragraph (f) of this section provides rules for leasehold improvements. Paragraph (g) of this section provides special rules for determining improvement costs in particular contexts, including indirect costs incurred during an improvement, removal costs, aggregation of related costs, and regulatory compliance costs. Paragraph (h) of this section provides a safe harbor for small taxpayers. Paragraph (i) provides a safe harbor for routine maintenance costs. Paragraph (j) of this section provides rules for determining whether amounts are paid for betterments to the unit of property. Paragraph (k) of this section provides rules for determining whether amounts are paid to restore the unit of property. Paragraph (l) of this section provides rules for amounts paid to adapt the unit of property to a new or different use. Paragraph (m) of this section provides an optional regulatory accounting method. Paragraph (n) of this section provides an election to capitalize repair and maintenance costs consistent with books and records. Paragraphs (o) and (p) of this section provide for the treatment and recovery of amounts capitalized under this section. Paragraphs (q) and (r) of this section provide for accounting method changes and state the effective/applicability date for the rules in this section.
  2. (b)Definitions. For purposes of this section, the following definitions apply:
    1. (1)Amount paid. In the case of a taxpayer using an accrual method of accounting, the terms amounts paid and payment mean a liability incurred (within the meaning of § 1.446-1(c)(1)(ii)). A liability may not be taken into account under this section prior to the taxable year during which the liability is incurred.
    2. (2)Personal property means tangible personal property as defined in § 1.48-1(c).
    3. (3)Real property means land and improvements thereto, such as buildings or other inherently permanent structures (including items that are structural components of the buildings or structures) that are not personal property as defined in paragraph (b)(2) of this section. Any property that constitutes other tangible property under § 1.48-1(d) is also treated as real property for purposes of this section. Local law is not controlling in determining whether property is real property for purposes of this section.
    4. (4)Owner means the taxpayer that has the benefits and burdens of ownership of the unit of property for Federal income tax purposes.
  3. (c)Coordination with other provisions of the Code
    1. (1)In general. Nothing in this section changes the treatment of any amount that is specifically provided for under any provision of the Code or the regulations other than section 162(a) or section 212 and the regulations under those sections. For example, see section 263A requiring taxpayers to capitalize the direct and allocable indirect costs of property produced and property acquired for resale.
    2. (2)Materials and supplies. A material or supply as defined in § 1.162-3(c)(1) that is acquired and used to improve a unit of tangible property is subject to this section and is not treated as a material or supply under § 1.162-3.
    3. (3)Example. The following example illustrates the rules of this paragraph (c):
  4. (d)Requirement to capitalize amounts paid for improvements. Except as provided in paragraph (h) or paragraph (n) of this section or under § 1.263(a)-1(f), a taxpayer generally must capitalize the related amounts (as defined in paragraph (g)(3) of this section) paid to improve a unit of property owned by the taxpayer. However, paragraph (f) of this section applies to the treatment of amounts paid to improve leased property. Section 263A provides the requirement to capitalize the direct and allocable indirect costs of property produced by the taxpayer and property acquired for resale. Section 1016 provides for the addition of capitalized amounts to the basis of the property, and section 168 governs the treatment of additions or improvements for depreciation purposes. For purposes of this section, a unit of property is improved if the amounts paid for activities performed after the property is placed in service by the taxpayer—
    1. (1)Are for a betterment to the unit of property (see paragraph (j) of this section);
    2. (2)Restore the unit of property (see paragraph (k) of this section); or
    3. (3)Adapt the unit of property to a new or different use (see paragraph (l) of this section).
  5. (e)Determining the unit of property
    1. (1)In general. The unit of property rules in this paragraph (e) apply only for purposes of section 263(a) and §§ 1.263(a)-1, 1.263(a)-2, 1.263(a)-3, and 1.162-3. Unless otherwise specified, the unit of property determination is based upon the functional interdependence standard provided in paragraph (e)(3)(i) of this section. However, special rules are provided for buildings (see paragraph (e)(2) of this section), plant property (see paragraph (e)(3)(ii) of this section), network assets (see paragraph (e)(3)(iii) of this section), leased property (see paragraph (e)(2)(v) of this section for leased buildings and paragraph (e)(3)(iv) of this section for leased property other than buildings), and improvements to property (see paragraph (e)(4) of this section). Additional rules are provided if a taxpayer has assigned different MACRS classes or depreciation methods to components of property or subsequently changes the class or depreciation method of a component or other item of property (see paragraph (e)(5) of this section). Property that is aggregated or subject to a general asset account election or accounted for in a multiple asset account (that is, pooled) may not be treated as a single unit of property.
    2. (2)Building
      1. (i)In general. Except as otherwise provided in paragraphs (e)(4), and (e)(5)(ii) of this section, in the case of a building (as defined in § 1.48-1(e)(1)), each building and its structural components (as defined in § 1.48-1(e)(2)) is a single unit of property (“building”). Paragraph (e)(2)(iii) of this section provides the unit of property for condominiums, paragraph (e)(2)(iv) of this section provides the unit of property for cooperatives, and paragraph (e)(2)(v) of this section provides the unit of property for leased buildings.
      2. (ii)Application of improvement rules to a building. An amount is paid to improve a building under paragraph (d) of this section if the amount is paid for an improvement under paragraphs (j), (k), or paragraph (l) of this section to any of the following:
        1. (A)Building structure. A building structure consists of the building (as defined in § 1.48-1(e)(1)), and its structural components (as defined in § 1.48-1(e)(2)), other than the structural components designated as buildings systems in paragraph (e)(2)(ii)(B) of this section.
        2. (B)Building system. Each of the following structural components (as defined in § 1.48-1(e)(2)), including the components thereof, constitutes a building system that is separate from the building structure, and to which the improvement rules must be applied—
          1. (1)Heating, ventilation, and air conditioning (“HVAC”) systems (including motors, compressors, boilers, furnace, chillers, pipes, ducts, radiators);
          2. (2)Plumbing systems (including pipes, drains, valves, sinks, bathtubs, toilets, water and sanitary sewer collection equipment, and site utility equipment used to distribute water and waste to and from the property line and between buildings and other permanent structures);
          3. (3)Electrical systems (including wiring, outlets, junction boxes, lighting fixtures and associated connectors, and site utility equipment used to distribute electricity from the property line to and between buildings and other permanent structures);
          4. (4)All escalators;
          5. (5)All elevators;
          6. (6)Fire-protection and alarm systems (including sensing devices, computer controls, sprinkler heads, sprinkler mains, associated piping or plumbing, pumps, visual and audible alarms, alarm control panels, heat and smoke detection devices, fire escapes, fire doors, emergency exit lighting and signage, and fire fighting equipment, such as extinguishers, and hoses);
          7. (7)Security systems for the protection of the building and its occupants (including window and door locks, security cameras, recorders, monitors, motion detectors, security lighting, alarm systems, entry and access systems, related junction boxes, associated wiring and conduit);
          8. (8)Gas distribution system (including associated pipes and equipment used to distribute gas to and from the property line and between buildings or permanent structures); and
          9. (9)Other structural components identified in published guidance in the Federal Register or in the Internal Revenue Bulletin (see § 601.601(d)(2)(ii)(b) of this chapter) that are excepted from the building structure under paragraph (e)(2)(ii)(A) of this section and are specifically designated as building systems under this section.
      3. (iii)Condominium
        1. (A)In general. In the case of a taxpayer that is the owner of an individual unit in a building with multiple units (such as a condominium), the unit of property (“condominium”) is the individual unit owned by the taxpayer and the structural components (as defined in § 1.48-1(e)(2)) that are part of the unit.
        2. (B)Application of improvement rules to a condominium. An amount is paid to improve a condominium under paragraph (d) of this section if the amount is paid for an improvement under paragraphs (j), (k), or paragraph (l) of this section to the building structure (as defined in paragraph (e)(2)(ii)(A) of this section) that is part of the condominium or to the portion of any building system (as defined in paragraph (e)(2)(ii)(B) of this section) that is part of the condominium. In the case of the condominium management association, the association must apply the improvement rules to the building structure or to any building system described under paragraphs (e)(2)(ii)(A) and (e)(2)(ii)(B) of this section.
      4. (iv)Cooperative
        1. (A)In general. In the case of a taxpayer that has an ownership interest in a cooperative housing corporation, the unit of property (“cooperative”) is the portion of the building in which the taxpayer has possessory rights and the structural components (as defined in § 1.48-1(e)(2)) that are part of the portion of the building subject to the taxpayer's possessory rights (cooperative).
        2. (B)Application of improvement rules to a cooperative. An amount is paid to improve a cooperative under paragraph (d) of this section if the amount is paid for an improvement under paragraphs (j), (k), or (l) of this section to the portion of the building structure (as defined in paragraph (e)(2)(ii)(A) of this section) in which the taxpayer has possessory rights or to the portion of any building system (as defined in paragraph (e)(2)(ii)(B) of this section) that is part of the portion of the building structure subject to the taxpayer's possessory rights. In the case of a cooperative housing corporation, the corporation must apply the improvement rules to the building structure or to any building system as described under paragraphs (e)(2)(ii)(A) and (e)(2)(ii)(B) of this section.
      5. (v)Leased building
        1. (A)In general. In the case of a taxpayer that is a lessee of all or a portion of a building (such as an office, floor, or certain square footage), the unit of property (“leased building property”) is each building and its structural components or the portion of each building subject to the lease and the structural components associated with the leased portion.
        2. (B)Application of improvement rules to a leased building. An amount is paid to improve a leased building property under paragraphs (d) and (f)(2) of this section if the amount is paid for an improvement, under paragraphs (j), (k), or (l) of this section, to any of the following:
          1. (1)Entire building. In the case of a taxpayer that is a lessee of an entire building, the building structure (as defined under paragraph (e)(2)(ii)(A) of this section) or any building system (as defined under paragraph (e)(2)(ii)(B) of this section) that is part of the leased building.
          2. (2)Portion of a building. In the case of a taxpayer that is a lessee of a portion of a building (such as an office, floor, or certain square footage), the portion of the building structure (as defined under paragraph (e)(2)(ii)(A) of this section) subject to the lease or the portion of any building system (as defined under paragraph (e)(2)(ii)(B) of this section) subject to the lease.
          3. (3)Property other than building
            1. (i)In general. Except as otherwise provided in paragraphs (e)(3), (e)(4), (e)(5), and (f)(1) of this section, in the case of real or personal property other than property described in paragraph (e)(2) of this section, all the components that are functionally interdependent comprise a single unit of property. Components of property are functionally interdependent if the placing in service of one component by the taxpayer is dependent on the placing in service of the other component by the taxpayer.
            2. (ii)Plant property
              1. (A)Definition. For purposes of this paragraph (e), the term plant property means functionally interdependent machinery or equipment, other than network assets, used to perform an industrial process, such as manufacturing, generation, warehousing, distribution, automated materials handling in service industries, or other similar activities.
              2. (B)Unit of property for plant property. In the case of plant property, the unit of property determined under the general rule of paragraph (e)(3)(i) of this section is further divided into smaller units comprised of each component (or group of components) that performs a discrete and major function or operation within the functionally interdependent machinery or equipment.
            3. (iii)Network assets
              1. (A)Definition. For purposes of this paragraph (e), the term network assets means railroad track, oil and gas pipelines, water and sewage pipelines, power transmission and distribution lines, and telephone and cable lines that are owned or leased by taxpayers in each of those respective industries. The term includes, for example, trunk and feeder lines, pole lines, and buried conduit. It does not include property that would be included as building structure or building systems under paragraphs (e)(2)(ii)(A) and (e)(2)(ii)(B) of this section, nor does it include separate property that is adjacent to, but not part of a network asset, such as bridges, culverts, or tunnels.
              2. (B)Unit of property for network assets. In the case of network assets, the unit of property is determined by the taxpayer's particular facts and circumstances except as otherwise provided in published guidance in the Federal Register or in the Internal Revenue Bulletin (see § 601.601(d)(2)(ii)(b) of this chapter). For these purposes, the functional interdependence standard provided in paragraph (e)(3)(i) of this section is not determinative.
            4. (iv)Leased property other than buildings. In the case of a taxpayer that is a lessee of real or personal property other than property described in paragraph (e)(2) of this section, the unit of property for the leased property is determined under paragraphs (e)(3)(i),(ii), (iii), and (e)(5) of this section except that, after applying the applicable rules under those paragraphs, the unit of property may not be larger than the property subject to the lease.
          4. (4)Improvements to property. An improvement to a unit of property generally is not a unit of property separate from the unit of property improved. For the unit of property for lessee improvements, see also paragraph (f)(2)(ii)) of this section. If a taxpayer elects to treat as a capital expenditure under § 1.162-3(d) the amount paid for a rotable spare part, temporary spare part, or standby emergency spare part, and such part is used in an improvement to a unit of property, then for purposes of applying paragraph (d) of this section to the unit of property improved, the part is not a unit of property separate from the unit of property improved.
          5. (5)Additional rules
            1. (i)Year placed in service. Notwithstanding the unit of property determination under paragraph (e)(3) of this section, a component (or a group of components) of a unit property must be treated as a separate unit of property if, at the time the unit of property is initially placed in service by the taxpayer, the taxpayer has properly treated the component as being within a different class of property under section 168(e) (MACRS classes) than the class of the unit of property of which the component is a part, or the taxpayer has properly depreciated the component using a different depreciation method than the depreciation method of the unit of property of which the component is a part.
            2. (ii)Change in subsequent taxable year. Notwithstanding the unit of property determination under paragraphs (e)(2), (3), (4), or (5)(i) of this section, in any taxable year after the unit of property is initially placed in service by the taxpayer, if the taxpayer or the Internal Revenue Service changes the treatment of that property (or any portion thereof) to a proper MACRS class or a proper depreciation method (for example, as a result of a cost segregation study or a change in the use of the property), then the taxpayer must change the unit of property determination for that property (or the portion thereof) under this section to be consistent with the change in treatment for depreciation purposes. Thus, for example, if a portion of a unit of property is properly reclassified to a MACRS class different from the MACRS class of the unit of property of which it was previously treated as a part, then the reclassified portion of the property should be treated as a separate unit of property for purposes of this section.
          6. (6)Examples. The following examples illustrate the application of this paragraph (e) and assume that the taxpayer has not made a general asset account election with regard to property or accounted for property in a multiple asset account. In addition, unless the facts specifically indicate otherwise, assume that the additional rules in paragraph (e)(5) of this section do not apply:
  6. (f)Improvements to leased property
    1. (1)In general. Except as provided in paragraph (h) of this section (safe harbor for small taxpayers) and under § 1.263(a)-1(f) (de minimis safe harbor), this paragraph (f) provides the exclusive rules for determining whether amounts paid by a taxpayer are for an improvement to a leased property and must be capitalized. In the case of a leased building or a leased portion of a building, an amount is paid to improve a leased property if the amount is paid for an improvement to any of the properties specified in paragraph (e)(2)(ii) of this section (for lessor improvements) or in paragraph (e)(2)(v)(B) of this section (for lessee improvements, except as provided in paragraph (f)(2)(ii) of this section). Section 1.263(a)-4 does not apply to amounts paid for improvements to leased property or to amounts paid for the acquisition or production of leasehold improvement property.
    2. (2)Lessee improvements
      1. (i)Requirement to capitalize. A taxpayer lessee must capitalize the related amounts, as determined under paragraph (g)(3) of this section, that it pays to improve, as defined under paragraph (d) of this section, a leased property except to the extent that section 110 applies to a construction allowance received by the lessee for the purpose of such improvement or when the improvement constitutes a substitute for rent. See § 1.61-8(c) for the treatment of lessee expenditures that constitute a substitute for rent. A taxpayer lessee must also capitalize the related amounts that a lessor pays to improve, as defined under paragraph (d) of this section, a leased property if the lessee is the owner of the improvement, except to the extent that section 110 applies to a construction allowance received by the lessee for the purpose of such improvement. An amount paid for a lessee improvement under this paragraph (f)(2)(i) is treated as an amount paid to acquire or produce a unit of real or personal property under § 1.263(a)-2(d)(1) of the regulations.
      2. (ii)Unit of property for lessee improvements. For purposes of determining whether an amount paid by a lessee constitutes a lessee improvement to a leased property under paragraph (f)(2)(i) of this section, the unit of property and the improvement rules are applied to the leased property in accordance with paragraph (e)(2)(v) (leased buildings) or paragraph (e)(3)(iv) (leased property other than buildings) of this section and include previous lessee improvements. However, if a lessee improvement is comprised of an entire building erected on leased property, then the unit of property for the building and the application of the improvement rules to the building are determined under paragraphs (e)(2)(i) and (e)(2)(ii) of this section.
    3. (3)Lessor improvements
      1. (i)Requirement to capitalize. A taxpayer lessor must capitalize the related amounts, as determined under paragraph (g)(3) of this section, that it pays directly, or indirectly through a construction allowance to the lessee, to improve, as defined in paragraph (d) of this section, a leased property when the lessor is the owner of the improvement or to the extent that section 110 applies to the construction allowance. A lessor must also capitalize the related amounts that the lessee pays to improve a leased property, as defined in paragraph (e) of this section, when the lessee's improvement constitutes a substitute for rent. See § 1.61-8(c) for treatment of expenditures by lessees that constitute a substitute for rent. Amounts capitalized by the lessor under this paragraph (f)(3)(i) may not be capitalized by the lessee. If a lessor improvement is comprised of an entire building erected on leased property, then the amount paid for the building is treated as an amount paid by the lessor to acquire or produce a unit of property under § 1.263(a)-2(d)(1). See paragraph (e)(2) of this section for the unit of property for a building and paragraph (e)(3) of this section for the unit of property for real or personal property other than a building.
      2. (ii)Unit of property for lessor improvements. In general, an amount capitalized as a lessor improvement under paragraph (f)(3)(i) of this section is not a unit of property separate from the unit of property improved. See paragraph (e)(4) of this section. However, if a lessor improvement is comprised of an entire building erected on leased property, then the unit of property for the building and the application of the improvement rules to the building are determined under paragraphs (e)(2)(i) and (e)(2)(ii) of this section.
    4. (4)Examples. The following examples illustrate the application of this paragraph (f) and do not address whether capitalization is required under another provision of the Code (for example, section 263A). For purposes of the following examples, assume that section 110 does not apply to the lessee and the amounts paid by the lessee are not a substitute for rent.
  7. (g)Special rules for determining improvement costs
    1. (1)Certain costs incurred during an improvement
      1. (i)In general. A taxpayer must capitalize all the direct costs of an improvement and all the indirect costs (including, for example, otherwise deductible repair costs) that directly benefit or are incurred by reason of an improvement. Indirect costs arising from activities that do not directly benefit and are not incurred by reason of an improvement are not required to be capitalized under section 263(a), regardless of whether the activities are performed at the same time as an improvement.
      2. (ii)Exception for individuals' residences. A taxpayer who is an individual may capitalize amounts paid for repairs and maintenance that are made at the same time as capital improvements to units of property not used in the taxpayer's trade or business or for the production of income if the amounts are paid as part of an improvement (for example, a remodeling) of the taxpayer's residence.
    2. (2)Removal costs
      1. (i)In general. If a taxpayer disposes of a depreciable asset, including a partial disposition under Prop. Reg. § 1.168(i)-1(e)(2)(ix) (September 19, 2013), or § 1.168(i)-8(d), for Federal income tax purposes and has taken into account the adjusted basis of the asset or component of the asset in realizing gain or loss, then the costs of removing the asset or component are not required to be capitalized under this section. If a depreciable asset is included in a general asset account under section 168(i)(4), and neither the regulations under section 168(i)(4) and § 1.168(i)-1(e)(3), apply to a disposition of such asset, or a portion of such asset under § 1.168(i)-1(e)(1)(ii), a loss is treated as being realized in the amount of zero upon the disposition of the asset solely for purposes of this paragraph (g)(2)(i). If a taxpayer disposes of a component of a unit of property, but the disposal of the component is not a disposition for Federal tax purposes, then the taxpayer must deduct or capitalize the costs of removing the component based on whether the removal costs directly benefit or are incurred by reason of a repair to the unit of property or an improvement to the unit of property. But see § 1.280B-1 for the rules applicable to demolition of structures.
      2. (ii)Examples. Thefollowing examples illustrate the application of paragraph (g)(2)(i) of this section and, unless otherwise stated, do not address whether capitalization is required under another provision of this section or another provision of the Code (for example, section 263A). For purposes of the following examples, assume that § 1.168(i)-1(e) or § 1.168(i)-8, applies and that § 1.280B-1 does not apply.
    3. (3)Related amounts. For purposes of paragraph (d) of this section, amounts paid to improve a unit of property include amounts paid over a period of more than one taxable year. Whether amounts are related to the same improvement depends on the facts and circumstances of the activities being performed.
    4. (4)Compliance with regulatory requirements. For purposes of this section, a Federal, state, or local regulator's requirement that a taxpayer perform certain repairs or maintenance on a unit of property to continue operating the property is not relevant in determining whether the amount paid improves the unit of property.
  8. (h)Safe harbor for small taxpayers
    1. (1)In general. A qualifying taxpayer (as defined in paragraph (h)(3) of this section) may elect to not apply paragraph (d) or paragraph (f) of this section to an eligible building property (as defined in paragraph (h)(4) of this section) if the total amount paid during the taxable year for repairs, maintenance, improvements, and similar activities performed on the eligible building property does not exceed the lesser of—
      1. (i)2 percent of the unadjusted basis (as defined under paragraph (h)(5) of this section) of the eligible building property; or
      2. (ii)$10,000.
    2. (2)Application with other safe harbor provisions. For purposes of paragraph (h)(1) of this section, amounts paid for repairs, maintenance, improvements, and similar activities performed on eligible building property include those amounts not capitalized under the de minimis safe harbor election under § 1.263(a)-1(f) and those amounts deemed not to improve property under the safe harbor for routine maintenance under paragraph (i) of this section.
    3. (3)Qualifying taxpayer
      1. (i)In general. For purposes of this paragraph (h), the term qualifying taxpayer means a taxpayer whose average annual gross receipts as determined under this paragraph (h)(3) for the three preceding taxable years is less than or equal to $10,000,000.
      2. (ii)Application to new taxpayers. If a taxpayer has been in existence for less than three taxable years, the taxpayer determines its average annual gross receipts for the number of taxable years (including short taxable years) that the taxpayer (or its predecessor) has been in existence.
      3. (iii)Treatment of short taxable year. In the case of any taxable year of less than 12 months (a short taxable year), the gross receipts shall be annualized by—
        1. (A)Multiplying the gross receipts for the short period by 12; and
        2. (B)Dividing the product determined in paragraph (h)(3)(iii)(A) of this section by the number of months in the short period.
      4. (iv)Definition of gross receipts. For purposes of applying paragraph (h)(3)(i) of this section, the term gross receipts means the taxpayer's receipts for the taxable year that are properly recognized under the taxpayer's methods of accounting used for Federal income tax purposes for the taxable year. For this purpose, gross receipts include total sales (net of returns and allowances) and all amounts received for services. In addition, gross receipts include any income from investments and from incidental or outside sources. For example, gross receipts include interest (including original issue discount and tax-exempt interest within the meaning of section 103), dividends, rents, royalties, and annuities, regardless of whether such amounts are derived in the ordinary course of the taxpayer's trade of business. Gross receipts are not reduced by cost of goods sold or by the cost of property sold if such property is described in section 1221(a)(1), (3), (4), or (5). With respect to sales of capital assets as defined in section 1221, or sales of property described in section 1221(a)(2) (relating to property used in a trade or business), gross receipts shall be reduced by the taxpayer's adjusted basis in such property. Gross receipts do not include the repayment of a loan or similar instrument (for example, a repayment of the principal amount of a loan held by a commercial lender) and, except to the extent of gain recognized, do not include gross receipts derived from a non-recognition transaction, such as a section 1031 exchange. Finally, gross receipts do not include amounts received by the taxpayer with respect to sales tax or other similar state and local taxes if, under the applicable state or local law, the tax is legally imposed on the purchaser of the good or service, and the taxpayer merely collects and remits the tax to the taxing authority. If, in contrast, the tax is imposed on the taxpayer under the applicable law, then gross receipts include the amounts received that are allocable to the payment of such tax.
    4. (4)Eligible building property. For purposes of this section, the term eligible building property refers to each unit of property defined in paragraph (e)(2)(i) (building), paragraph (e)(2)(iii)(A) (condominium), paragraph (e)(2)(iv)(A) (cooperative), or paragraph (e)(2)(v)(A) (leased building or portion of building) of this section, as applicable, that has an unadjusted basis of $1,000,000 or less.
    5. (5)Unadjusted basis
      1. (i)Eligible building property owned by taxpayer. For purposes of this section, the unadjusted basis of eligible building property owned by the taxpayer means the basis as determined under section 1012, or other applicable sections of Chapter 1, including subchapters O (relating to gain or loss on dispositions of property), C (relating to corporate distributions and adjustments), K (relating to partners and partnerships), and P (relating to capital gains and losses). Unadjusted basis is determined without regard to any adjustments described in section 1016(a)(2) or (3) or to amounts for which the taxpayer has elected to treat as an expense (for example, under sections 179, 179B, or 179C).
      2. (ii)Eligible building property leased to the taxpayer. For purposes of this section, the unadjusted basis of eligible building property leased to the taxpayer is the total amount of (undiscounted) rent paid or expected to be paid by the lessee under the lease for the entire term of the lease, including renewal periods if all the facts and circumstances in existence during the taxable year in which the lease is entered indicate a reasonable expectancy of renewal. Section 1.263(a)-4(f)(5)(ii) provides the factors that are significant in determining whether there exists a reasonable expectancy of renewal for purposes of this paragraph.
    6. (6)Time and manner of election. A taxpayer makes the election described in paragraph (h)(1) of this section by attaching a statement to the taxpayer's timely filed original Federal tax return (including extensions) for the taxable year in which amounts are paid for repairs, maintenance, improvements, and similar activities performed on the eligible building property providing that such amounts qualify under the safe harbor provided in paragraph (h)(1) of this section. Sections 301.9100-1 through 301.9100-3 of this chapter provide the rules governing extensions of the time to make regulatory elections. The statement must be titled, “Section 1.263(a)-3(h) Safe Harbor Election for Small Taxpayers” and include the taxpayer's name, address, taxpayer identification number, and a description of each eligible building property to which the taxpayer is applying the election. In the case of an S corporation or a partnership, the election is made by the S corporation or by the partnership, and not by the shareholders or partners. An election may not be made through the filing of an application for change in accounting method or, before obtaining the Commissioner's consent to make a late election, by filing an amended Federal tax return. A taxpayer may not revoke an election made under this paragraph (h). The time and manner of making the election under this paragraph (h) may be modified through guidance of general applicability (see §§ 601.601(d)(2) and 601.602 of this chapter).
    7. (7)Treatment of safe harbor amounts. Amounts paid by the taxpayer for repairs, maintenance, improvements, and similar activities to which the taxpayer properly applies the safe harbor under paragraph (h)(1) of this section and for which the taxpayer properly makes the election under paragraph (h)(6) of this section are not treated as improvements under paragraph (d) or (f) of this section and may be deducted under § 1.162-1 or § 1.212-1, as applicable, in the taxable year these amounts are paid, provided the amounts otherwise qualify for a deduction under these sections.
    8. (8)Safe harbor exceeded. If total amounts paid by a qualifying taxpayer during the taxable year for repairs, maintenance, improvements, and similar activities performed on an eligible building property exceed the safe harbor limitations specified in paragraph (h)(1) of this section, then the safe harbor election is not available for that eligible building property and the taxpayer must apply the general improvement rules under this section to determine whether amounts are for improvements to the unit of property, including the safe harbor for routine maintenance under paragraph (i) of this section. The taxpayer may also elect to apply the de minimis safe harbor under § 1.263(a)-1(f) to amounts qualifying under that safe harbor irrespective of the application of this paragraph (h).
    9. (9)Modification of safe harbor amounts. The amount limitations provided in paragraphs (h)(1)(i), (h)(1)(ii), and (h)(3) of this section may be modified through published guidance in the Federal Register or in the Internal Revenue Bulletin (see § 601.601(d)(2)(ii)(b) of this chapter).
    10. (10)Examples. The following examples illustrate the rules of this paragraph (h). Assume that § 1.212-1 does not apply to the amounts paid.
      1. (i)Safe harbor for routine maintenance on property
        1. (1)In general. An amount paid for routine maintenance (as defined in paragraph (i)(1)(i) or (i)(1)(ii) of this section, as applicable) on a unit of tangible property, or in the case of a building, on any of the properties designated in paragraphs (e)(2)(ii), (e)(2)(iii)(B), (e)(2)(iv)(B), or paragraph (e)(2)(v)(B) of this section, is deemed not to improve that unit of property.
          1. (i)Routine maintenance for buildings. Routine maintenance for a building unit of property is the recurring activities that a taxpayer expects to perform as a result of the taxpayer's use of any of the properties designated in paragraphs (e)(2)(ii), (e)(2)(iii)(B), (e)(2)(iv)(B), or (e)(2)(v)(B) of this section to keep the building structure or each building system in its ordinarily efficient operating condition. Routine maintenance activities include, for example, the inspection, cleaning, and testing of the building structure or each building system, and the replacement of damaged or worn parts with comparable and commercially available replacement parts. Routine maintenance may be performed any time during the useful life of the building structure or building systems. However, the activities are routine only if the taxpayer reasonably expects to perform the activities more than once during the 10-year period beginning at the time the building structure or the building system upon which the routine maintenance is performed is placed in service by the taxpayer. A taxpayer's expectation will not be deemed unreasonable merely because the taxpayer does not actually perform the maintenance a second time during the 10-year period, provided that the taxpayer can otherwise substantiate that its expectation was reasonable at the time the property was placed in service. Factors to be considered in determining whether maintenance is routine and whether a taxpayer's expectation is reasonable include the recurring nature of the activity, industry practice, manufacturers' recommendations, and the taxpayer's experience with similar or identical property. With respect to a taxpayer that is a lessor of a building or a part of the building, the taxpayer's use of the building unit of property includes the lessee's use of its unit of property.
          2. (ii)Routine maintenance for property other than buildings. Routine maintenance for property other than buildings is the recurring activities that a taxpayer expects to perform as a result of the taxpayer's use of the unit of property to keep the unit of property in its ordinarily efficient operating condition. Routine maintenance activities include, for example, the inspection, cleaning, and testing of the unit of property, and the replacement of damaged or worn parts of the unit of property with comparable and commercially available replacement parts. Routine maintenance may be performed any time during the useful life of the unit of property. However, the activities are routine only if, at the time the unit of property is placed in service by the taxpayer, the taxpayer reasonably expects to perform the activities more than once during the class life (as defined in paragraph (i)(4) of this section) of the unit of property. A taxpayer's expectation will not be deemed unreasonable merely because the taxpayer does not actually perform the maintenance a second time during the class life of the unit of property, provided that the taxpayer can otherwise substantiate that its expectation was reasonable at the time the property was placed in service. Factors to be considered in determining whether maintenance is routine and whether the taxpayer's expectation is reasonable include the recurring nature of the activity, industry practice, manufacturers' recommendations, and the taxpayer's experience with similar or identical property. With respect to a taxpayer that is a lessor of a unit of property, the taxpayer's use of the unit of property includes the lessee's use of the unit of property.
        2. (2)Rotable and temporary spare parts. Except as provided in paragraph (i)(3) of this section, for purposes of paragraph (i)(1)(ii) of this section, amounts paid for routine maintenance include routine maintenance performed on (and with regard to) rotable and temporary spare parts.
        3. (3)Exceptions. Routine maintenance does not include the following:
          1. (i)Amounts paid for a betterment to a unit of property under paragraph (j) of this section;
          2. (ii)Amounts paid for the replacement of a component of a unit of property for which the taxpayer has properly deducted a loss for that component (other than a casualty loss under § 1.165-7) (see paragraph (k)(1)(i) of this section);
          3. (iii)Amounts paid for the replacement of a component of a unit of property for which the taxpayer has properly taken into account the adjusted basis of the component in realizing gain or loss resulting from the sale or exchange of the component (see paragraph (k)(1)(ii) of this section);
          4. (iv)Amounts paid for the restoration of damage to a unit of property for which the taxpayer is required to take a basis adjustment as a result of a casualty loss under section 165, or relating to a casualty event described in section 165, subject to the limitation in paragraph (k)(4) of this section (see paragraph (k)(1)(iii) of this section);
          5. (v)Amounts paid to return a unit of property to its ordinarily efficient operating condition, if the property has deteriorated to a state of disrepair and is no longer functional for its intended use (see paragraph (k)(1)(iv) of this section);
          6. (vi)Amounts paid to adapt a unit of property to a new or different use under paragraph (l) of this section;
          7. (vii)Amounts paid for repairs, maintenance, or improvement of network assets (as defined in paragraph (e)(3)(iii)(A) of this section); or
          8. (viii)Amounts paid for repairs, maintenance, or improvement of rotable and temporary spare parts to which the taxpayer applies the optional method of accounting for rotable and temporary spare parts under § 1.162-3(e).
        4. (4)Class life. The class life of a unit of property is the recovery period prescribed for the property under sections 168(g)(2) and (3) for purposes of the alternative depreciation system, regardless of whether the property is depreciated under section 168(g). For purposes of determining class life under this section, section 168(g)(3)(A) (relating to tax-exempt use property subject to lease) does not apply. If the unit of property is comprised of components with different class lives, then the class life of the unit of property is deemed to be the same as the component with the longest class life.
        5. (5)Coordination with section 263A. Amounts paid for routine maintenance under this paragraph (i) may be subject to capitalization under section 263A if these amounts comprise the direct or allocable indirect costs of other property produced by the taxpayer or property acquired for resale. See, for example, § 1.263A-1(e)(3)(ii)(O) requiring taxpayers to capitalize the cost of repairing equipment or facilities allocable to property produced or property acquired for resale.
        6. (6)Examples. The following examples illustrate the application of this paragraph (i) and, unless otherwise stated, do not address the treatment under other provisions of the Code (for example, section 263A). In addition, unless otherwise stated, assume that the taxpayer has not applied the optional method of accounting for rotable and temporary spare parts under § 1.162-3(e).
  9. (j)Capitalization of betterments
    1. (1)In general. A taxpayer must capitalize as an improvement an amount paid for a betterment to a unit of property. An amount is paid for a betterment to a unit of property only if it—
      1. (i)Ameliorates a material condition or defect that either existed prior to the taxpayer's acquisition of the unit of property or arose during the production of the unit of property, whether or not the taxpayer was aware of the condition or defect at the time of acquisition or production;
      2. (ii)Is for a material addition, including a physical enlargement, expansion, extension, or addition of a major component (as defined in paragraph (k)(6) of this section) to the unit of property or a material increase in the capacity, including additional cubic or linear space, of the unit of property; or
      3. (iii)Is reasonably expected to materially increase the productivity, efficiency, strength, quality, or output of the unit of property.
    2. (2)Application of betterment rules
      1. (i)In general. The applicability of each quantitative and qualitative factor provided in paragraphs (j)(1)(ii) and (j)(1)(iii) of this section to a particular unit of property depends on the nature of the unit of property. For example, if an addition or an increase in a particular factor cannot be measured in the context of a specific type of property, this factor is not relevant in the determination of whether an amount has been paid for a betterment to the unit of property.
      2. (ii)Application of betterment rules to buildings. An amount is paid to improve a building if it is paid for a betterment, as defined under paragraph (j)(1) of this section, to a property specified under paragraph (e)(2)(ii) (building), paragraph (e)(2)(iii)(B) (condominium), paragraph (e)(2)(iv)(B) (cooperative), or paragraph (e)(2)(v)(B) (leased building or leased portion of building) of this section. For example, an amount is paid to improve a building if it is paid for an increase in the efficiency of the building structure or any one of its building systems (for example, the HVAC system).
      3. (iii)Unavailability of replacement parts. If a taxpayer replaces a part of a unit of property that cannot reasonably be replaced with the same type of part (for example, because of technological advancements or product enhancements), the replacement of the part with an improved, but comparable, part does not, by itself, result in a betterment to the unit of property.
      4. (iv)Appropriate comparison
        1. (A)In general. In cases in which an expenditure is necessitated by normal wear and tear or damage to the unit of property that occurred during the taxpayer's use of the unit of property, the determination of whether an expenditure is for the betterment of the unit of property is made by comparing the condition of the property immediately after the expenditure with the condition of the property immediately prior to the circumstances necessitating the expenditure.
        2. (B)Normal wear and tear. If the expenditure is made to correct the effects of normal wear and tear to the unit of property that occurred during the taxpayer's use of the unit of property, the condition of the property immediately prior to the circumstances necessitating the expenditure is the condition of the property after the last time the taxpayer corrected the effects of normal wear and tear (whether the amounts paid were for maintenance or improvements) or, if the taxpayer has not previously corrected the effects of normal wear and tear, the condition of the property when placed in service by the taxpayer.
        3. (C)Damage to property. If the expenditure is made to correct damage to a unit of property that occurred during the taxpayer's use of the unit of property, the condition of the property immediately prior to the circumstances necessitating the expenditure is the condition of the property immediately prior to damage.
    3. (3)Examples. The following examples illustrate the application of this paragraph (j) only and do not address whether capitalization is required under another provision of this section or another provision of the Internal Revenue Code (for example, section 263A). Unless otherwise provided, assume that the appropriate comparison in paragraph (j)(2)(iv) of this section is not applicable under the facts.
  10. (k)Capitalization of restorations
    1. (1)In general. A taxpayer must capitalize as an improvement an amount paid to restore a unit of property, including an amount paid to make good the exhaustion for which an allowance is or has been made. An amount restores a unit of property only if it—
      1. (i)Is for the replacement of a component of a unit of property for which the taxpayer has properly deducted a loss for that component, other than a casualty loss under § 1.165-7;
      2. (ii)Is for the replacement of a component of a unit of property for which the taxpayer has properly taken into account the adjusted basis of the component in realizing gain or loss resulting from the sale or exchange of the component;
      3. (iii)Is for the restoration of damage to a unit of property for which the taxpayer is required to take a basis adjustment as a result of a casualty loss under section 165, or relating to a casualty event described in section 165, subject to the limitation in paragraph (k)(4) of this section;
      4. (iv)Returns the unit of property to its ordinarily efficient operating condition if the property has deteriorated to a state of disrepair and is no longer functional for its intended use;
      5. (v)Results in the rebuilding of the unit of property to a like-new condition as determined under paragraph (k)(5) of this section after the end of its class life as defined in paragraph (i)(4) of this section; or
      6. (vi)Is for the replacement of a part or combination of parts that comprise a major component or a substantial structural part of a unit of property as determined under paragraph (k)(6) of this section.
    2. (2)Application of restorations to buildings. An amount is paid to improve a building if it is paid to restore, as defined under paragraph (k)(1) of this section, a property specified under paragraph (e)(2)(ii) (building), paragraph (e)(2)(iii)(B) (condominium), paragraph (e)(2)(iv)(B) (cooperative), or paragraph (e)(2)(v)(B) (leased building or portion of building) of this section. For example, an amount is paid to improve a building if it is paid for the replacement of a part or combination of parts that comprise a major component or substantial structural part of the building structure or any one of its building systems (for example, the HVAC system). See paragraph (k)(6) of this section.
    3. (3)Exception for losses based on salvage value. A taxpayer is not required to treat as a restoration amounts paid under paragraph (k)(1)(i) or paragraph (k)(1)(ii) of this section if the unit of property has been fully depreciated and the loss is attributable only to remaining salvage value as computed for federal income tax purposes.
    4. (4)Restoration of damage from casualty
      1. (i)Limitation. For purposes of paragraph (k)(1)(iii) of this section, the amount paid for restoration of damage to the unit of property that must be capitalized under this paragraph (k) is limited to the excess (if any) of—
        1. (A)The amount prescribed by § 1.1011-1 as the adjusted basis of the single, identifiable property (under § 1.167-7(b)(2)(i)) for determining the loss allowable on account of the casualty, over
        2. (B)The amount paid for restoration of damage to the unit of property under paragraph (k)(1)(iii) of this section that also constitutes an improvement under any other provision of paragraph (k)(1) of this section.
      2. (ii)Amounts in excess of limitation. The amounts paid for restoration of damage to a unit of property as described in paragraph (k)(1)(iii) of this section, but that exceed the limitation provided in paragraph (k)(4)(i) of this section, must be treated in accordance with the provisions of the Internal Revenue Code and regulations that are otherwise applicable. See, for example, § 1.162-4 (repairs and maintenance); § 1.263(a)-2 (costs to acquire and produce units of property); and § 1.263(a)-3 (costs to improve units of property).
    5. (5)Rebuild to like-new condition. For purposes of paragraph (k)(1)(v) of this section, a unit of property is rebuilt to a like-new condition if it is brought to the status of new, rebuilt, remanufactured, or a similar status under the terms of any federal regulatory guideline or the manufacturer's original specifications. Generally, a comprehensive maintenance program, even though substantial, does not return a unit of property to a like-new condition.
    6. (6)Replacement of a major component or a substantial structural part
      1. (i)In general. To determine whether an amount is for the replacement of a part or a combination of parts that comprise a major component or a substantial structural part of the unit of property under paragraph (k)(1)(vi) of this section, it is appropriate to consider all the facts and circumstances. These facts and circumstances include the quantitative and qualitative significance of the part or combination of parts in relation to the unit of property.
        1. (A)Major component. A major component is a part or combination of parts that performs a discrete and critical function in the operation of the unit of property. An incidental component of the unit of property, even though such component performs a discrete and critical function in the operation of the unit of property, generally will not, by itself, constitute a major component.
        2. (B)Substantial structural part. A substantial structural part is a part or combination of parts that comprises a large portion of the physical structure of the unit of property.
      2. (ii)Major components and substantial structural parts of buildings. In the case of a building, an amount is for the replacement of a major component or a substantial structural part of the building unit of property if—
        1. (A)The replacement includes a part or combination of parts that comprise a major component (as defined in paragraph (k)(6)(i)(A) of this section), or a significant portion of a major component, of any of the properties designated in paragraph (e)(2)(ii) (building), paragraph (e)(2)(iii)(B) (condominium), paragraph (e)(2)(iv)(B) (cooperative), or paragraph (e)(2)(v)(B) (leased building or leased portion of a building) of this section; or
        2. (B)The replacement includes a part or combination of parts that comprises a large portion of the physical structure of any of the properties designated in paragraph (e)(2)(ii) (building), paragraph (e)(2)(iii)(B) (condominium), paragraph (e)(2)(iv)(B) (cooperative), or paragraph (e)(2)(v)(B) (leased building or portion of building) of this section.
    7. (7)Examples. The following examples illustrate the application of this paragraph (k) only and do not address whether capitalization is required under another provision of this section or another provision of the Code (for example, section 263A). Unless otherwise stated, assume that the taxpayer has not properly deducted a loss for, nor taken into account the adjusted basis on a sale or exchange of, any unit of property, asset, or component of a unit of property that is replaced.
  11. (l)Capitalization of amounts to adapt property to a new or different use
    1. (1)In general. A taxpayer must capitalize as an improvement an amount paid to adapt a unit of property to a new or different use. In general, an amount is paid to adapt a unit of property to a new or different use if the adaptation is not consistent with the taxpayer's ordinary use of the unit of property at the time originally placed in service by the taxpayer.
    2. (2)Application of adaption rule to buildings. In the case of a building, an amount is paid to improve a building if it is paid to adapt to a new or different use a property specified under paragraph (e)(2)(ii) (building), paragraph (e)(2)(iii)(B) (condominium), paragraph (e)(2)(iv)(B) (cooperative), or paragraph (e)(2)(v)(B) (leased building or leased portion of building) of this section. For example, an amount is paid to improve a building if it is paid to adapt the building structure or any one of its buildings systems to a new or different use.
    3. (3)Examples. The following examples illustrate the application of this paragraph (l) only and do not address whether capitalization is required under another provision of this section or under another provision of the Code (for example, section 263A). Unless otherwise stated, assume that the taxpayer has not properly deducted a loss for any unit of property, asset, or component of a unit of property that is removed and replaced.
  12. (m)Optional regulatory accounting method
    1. (1)In general. This paragraph (m) provides an optional simplified method (the regulatory accounting method) for regulated taxpayers to determine whether amounts paid to repair, maintain, or improve tangible property are to be treated as deductible expenses or capital expenditures. A taxpayer that uses the regulatory accounting method described in paragraph (m)(3) of this section must use that method for property subject to regulatory accounting instead of determining whether amounts paid to repair, maintain, or improve property are capital expenditures or deductible expenses under the general principles of sections 162(a), 212, and 263(a). Thus, the capitalization rules in paragraph (d) (and the routine maintenance safe harbor described in paragraph (i)) of this section do not apply to amounts paid to repair, maintain, or improve property subject to regulatory accounting by taxpayers that use the regulatory accounting method under this paragraph (m).
    2. (2)Eligibility for regulatory accounting method. A taxpayer that is engaged in a trade or business in a regulated industry is a regulated taxpayer and may use the regulatory accounting method under this paragraph (m). For purposes of this paragraph (m), a taxpayer is in a regulated industry only if the taxpayer is subject to the regulatory accounting rules of the Federal Energy Regulatory Commission (FERC), the Federal Communications Commission (FCC), or the Surface Transportation Board (STB).
    3. (3)Description of regulatory accounting method. Under the regulatory accounting method, a taxpayer must follow the method of accounting for regulatory accounting purposes that it is required to follow for FERC, FCC, or STB (whichever is applicable) in determining whether an amount paid repairs, maintains, or improves property under this section. Therefore, a taxpayer must capitalize for Federal income tax purposes an amount paid that is capitalized as an improvement for regulatory accounting purposes. A taxpayer may not capitalize for Federal income tax purposes under this section an amount paid that is not capitalized as an improvement for regulatory accounting purposes. A taxpayer that uses the regulatory accounting method must use that method for all of its tangible property that is subject to regulatory accounting rules. The method does not apply to tangible property that is not subject to regulatory accounting rules. The method also does not apply to property for the taxable years in which the taxpayer elected to apply the repair allowance under § 1.167(a)-11(d)(2). The regulatory accounting method is a method of accounting under section 446(a).
    4. (4)Examples. The following examples illustrate the application of this paragraph (m):
  13. (n)Election to capitalize repair and maintenance costs
    1. (1)In general. A taxpayer may elect to treat amounts paid during the taxable year for repair and maintenance (as defined under § 1.162-4) to tangible property as amounts paid to improve that property under this section and as an asset subject to the allowance for depreciation if the taxpayer incurs these amounts in carrying on the taxpayer's trade or business and if the taxpayer treats these amounts as capital expenditures on its books and records regularly used in computing income (“books and records”). A taxpayer that elects to apply this paragraph (n) in a taxable year must apply this paragraph to all amounts paid for repair and maintenance to tangible property that it treats as capital expenditures on its books and records in that taxable year. Any amounts for which this election is made shall not be treated as amounts paid for repair or maintenance under § 1.162-4.
    2. (2)Time and manner of election. A taxpayer makes this election under this paragraph (n) by attaching a statement to the taxpayer's timely filed original Federal tax return (including extensions) for the taxable year in which the taxpayer pays amounts described under paragraph (n)(1) of this paragraph. Sections 301.9100-1 through 301.9100-3 of this chapter provide the rules governing extensions of the time to make regulatory elections. The statement must be titled “Section 1.263(a)-3(n) Election” and include the taxpayer's name, address, taxpayer identification number, and a statement that the taxpayer is making the election to capitalize repair and maintenance costs under § 1.263(a)-3(n). In the case of a consolidated group filing a consolidated income tax return, the election is made for each member of the consolidated group by the common parent, and the statement must also include the names and taxpayer identification numbers of each member for which the election is made. In the case of an S corporation or a partnership, the election is made by the S corporation or partnership and not by the shareholders or partners. A taxpayer making this election for a taxable year must treat any amounts paid for repairs and maintenance during the taxable year that are capitalized on the taxpayer's books and records as improvements to tangible property. The taxpayer must begin to depreciate the cost of such improvements amounts when they are placed in service by the taxpayer under the applicable provisions of the Code and regulations. An election may not be made through the filing of an application for change in accounting method or, before obtaining the Commissioner's consent to make a late election, by filing an amended Federal tax return. The time and manner of electing to capitalize repair and maintenance costs under this paragraph (n) may be modified through guidance of general applicability (see §§ 601.601(d)(2) and 601.602 of this chapter).
    3. (3)Exception. This paragraph (n) does not apply to amounts paid for repairs or maintenance of rotable or temporary spare parts to which the taxpayer applies the optional method of accounting for rotable and temporary spare parts under § 1.162-3(e).
    4. (4)Examples. The following examples illustrate the application of this paragraph (n):
  14. (o)Treatment of capital expenditures. Amounts required to be capitalized under this section are capital expenditures and must be taken into account through a charge to capital account or basis, or in the case of property that is inventory in the hands of a taxpayer, through inclusion in inventory costs.
  15. (p)Recovery of capitalized amounts. Amounts that are capitalized under this section are recovered through depreciation, cost of goods sold, or by an adjustment to basis at the time the property is placed in service, sold, used, or otherwise disposed of by the taxpayer. Cost recovery is determined by the applicable Code and regulation provisions relating to the use, sale, or disposition of property.
  16. (q)Accounting method changes. Except as otherwise provided in this section, a change to comply with this section is a change in method of accounting to which the provisions of sections 446 and 481 and the accompanying regulations apply. A taxpayer seeking to change to a method of accounting permitted in this section must secure the consent of the Commissioner in accordance with § 1.446-1(e) and follow the administrative procedures issued under § 1.446-1(e)(3)(ii) for obtaining the Commissioner's consent to change its accounting method.
  17. (r)Effective/applicability date
    1. (1)In general. Except for paragraphs (h), (m), and (n) of this section, this section applies to taxable years beginning on or after January 1, 2014. Paragraphs (h), (m), and (n) of this section apply to amounts paid in taxable years beginning on or after January 1, 2014. Except as provided in paragraphs (r)(2) and (r)(3) of this section, § 1.263(a)-3 as contained in 26 CFR part 1 edition revised as of April 1, 2011, applies to taxable years beginning before January 1, 2014.
    2. (2)Early application of this section
      1. (i)In general. Except for paragraphs (h), (m), and (n) of this section, a taxpayer may choose to apply this section to taxable years beginning on or after January 1, 2012.
