Materials and supplies

(a) In general—(1) Non-incidental materials and supplies. Except as provided in paragraphs (d), (e), and (f) of this section, amounts paid to acquire or produce materials and supplies (as defined in paragraph (c) of this section) are deductible in the taxable year in which the materials and supplies are first used in the taxpayer's operations or are consumed in the taxpayer's operations.

(2) Incidental materials and supplies. Amounts paid to acquire or produce incidental materials and supplies (as defined in paragraph (c) of this section) that are carried on hand and for which no record of consumption is kept or of which physical inventories at the beginning and end of the taxable year are not taken, are deductible in the taxable year in which these amounts are paid, provided taxable income is clearly reflected.

(3) Use or consumption of rotable and temporary spare parts. Except as provided in paragraphs (d), (e), and (f) of this section, for purposes of paragraph (a)(1) of this section, rotable and temporary spare parts (defined under paragraph (c)(2) of this section) are first used in the taxpayer's operations or are consumed in the taxpayer's operations in the taxable year in which the taxpayer disposes of the parts.

(b) Coordination with other provisions of the Internal Revenue Code. Nothing in this section changes the treatment of any amount that is specifically provided for under any provision of the Internal Revenue Code (Code) or regulations other than section 162(a) or section 212 and the regulations under those sections. For example, see § 1.263(a)-3, which requires taxpayers to capitalize amounts paid to improve tangible property and section 263A and the regulations under section 263A, which require taxpayers to capitalize the direct and allocable indirect costs, including the cost of materials and supplies, of property produced by the taxpayer and property acquired for resale. See also § 1.471-1, which requires taxpayers to include in inventory certain materials and supplies.

(c) Definitions—(1) Materials and supplies. For purposes of this section, materials and supplies means tangible property that is used or consumed in the taxpayer's operations that is not inventory and that—

(i) Is a component acquired to maintain, repair, or improve a unit of tangible property (as determined under § 1.263(a)-3(e)) owned, leased, or serviced by the taxpayer and that is not acquired as part of any single unit of tangible property;

(vi) Only available on special order and not readily available from a vendor or manufacturer;

(vii) Not subject to normal periodic replacement;

(viii) Not interchangeable in other machines or equipment;

(ix) [Reserved]

(x) Not acquired in quantity (generally only one is on hand for each piece of machinery or equipment); and

(xi) Not repaired and reused.

(4) Economic useful life—(i) General rule. The economic useful life of a unit of property is not necessarily the useful life inherent in the property but is the period over which the property may reasonably be expected to be useful to the taxpayer or, if the taxpayer is engaged in a trade or business or an activity for the production of income, the period over which the property may reasonably be expected to be useful to the taxpayer in its trade or business or for the production of income, as applicable. The factors that must be considered in determining this period are provided under § 1.167(a)-1(b).

(ii) Taxpayers with an applicable financial statement. For taxpayers with an applicable financial statement (as defined in paragraph (c)(4)(iii) of this section), the economic useful life of a unit of property, solely for the purposes of applying the provisions of this paragraph (c), is the useful life initially used by the taxpayer for purposes of determining depreciation in its applicable financial statement, regardless of any salvage value of the property. If a taxpayer does not have an applicable financial statement for the taxable year in which a unit of property was originally acquired or produced, the economic useful life of the unit of property must be determined under paragraph (c)(4)(i) of this section. Further, if a taxpayer treats amounts paid for a unit of property as an expense in its applicable financial statement on a basis other than the useful life of the property or if a taxpayer does not depreciate the unit of property on its applicable financial statement, the economic useful life of the unit of property must be determined under paragraph (c)(4)(i) of this section. For example, if a taxpayer has a policy of treating as an expense on its applicable financial statement amounts paid for a unit of property costing less than a certain dollar amount, notwithstanding that the unit of property has a useful life of more than one year, the economic useful life of the unit of property must be determined under paragraph (c)(4)(i) of this section.

(iii) Definition of applicable financial statement. The taxpayer's applicable financial statement is the taxpayer's financial statement listed in paragraphs (c)(4)(iii)(A) through (C) of this section that has the highest priority (including within paragraph (c)(4)(iii)(B) of this section). The financial statements are, in descending priority—

(A) A financial statement required to be filed with the Securities and Exchange Commission (SEC) (the 10-K or the Annual Statement to Shareholders);

(B) A certified audited financial statement that is accompanied by the report of an independent certified public accountant (or in the case of a foreign entity, by the report of a similarly qualified independent professional), that is used for—

(1) Credit purposes;

(2) Reporting to shareholders, partners, or similar persons; or

(3) Any other substantial non-tax purpose; or

(C) A financial statement (other than a tax return) required to be provided to the federal or a state government or any federal or state agency (other than the SEC or the Internal Revenue Service).

(5) Amount paid. For purposes of this section, in the case of a taxpayer using an accrual method of accounting, the terms amount 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.

(6) Produce. For purposes of this section, produce means construct, build, install, manufacture, develop, create, raise, or grow. This definition is intended to have the same meaning as the definition used for purposes of section 263A(g)(1) and § 1.263A-2(a)(1)(i), except that improvements are excluded from the definition in this paragraph (c)(6) and are separately defined and addressed in § 1.263(a)-3. Amounts paid to produce materials and supplies are subject to section 263A.

(d) Election to capitalize and depreciate certain materials and supplies—(1) In general. A taxpayer may elect to treat as a capital expenditure and to treat as an asset subject to the allowance for depreciation the cost of any rotable spare part, temporary spare part, or standby emergency spare part as defined in paragraph (c)(2) or (c)(3) of this section. Except as specified in paragraph (d)(2) of this section, an election made under this paragraph (d) applies to amounts paid during the taxable year to acquire or produce any rotable, temporary, or standby emergency spare part to which paragraph (a) of this section would apply (but for the election under this paragraph (d)). Any property for which this election is made shall not be treated as a material or a supply.

(2) Exceptions. A taxpayer may not elect to capitalize and depreciate under this paragraph (d) any amount paid to acquire or produce a rotable, temporary, or standby emergency spare part defined in paragraph (c)(2) or (c)(3) of this section if—

(i) The rotable, temporary, or standby emergency spare part is intended to be used as a component of a unit of property under paragraph (c)(1)(iii), (iv), or (v) of this section;

(ii) The rotable, temporary, or standby emergency spare part is intended to be used as a component of a property described in paragraph (c)(1)(i) and the taxpayer cannot or has not elected to capitalize and depreciate that property under this paragraph (d); or

(iii) The amount is paid to acquire or produce a rotable or temporary spare part and the taxpayer uses the optional method of accounting for rotable and temporary spare parts under paragraph (e) to of this section.

(3) Manner of electing. A taxpayer makes the election under this paragraph (d) by capitalizing the amounts paid to acquire or produce a rotable, temporary, or standby emergency spare part in the taxable year the amounts are paid and by beginning to depreciate the costs when the asset is placed in service by the taxpayer for purposes of determining depreciation under the applicable provisions of the Internal Revenue Code and the Treasury Regulations. Section 1.263(a)-2 provides for the treatment of amounts paid to acquire or produce real or personal tangible property. A taxpayer must make the election under this paragraph (d) in its timely filed original Federal tax return (including extensions) for the taxable year the asset is placed in service by the taxpayer for purposes of determining depreciation. Sections 301.9100-1 through 301.9100-3 of this chapter provide the rules governing extensions of the time to make regulatory elections. 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 may make an election for each rotable, temporary, or standby emergency spare part that qualifies for the election under this paragraph (d). This election does not apply to an asset or a portion thereof placed in service and disposed of in the same taxable year. A taxpayer may revoke an election made under this paragraph (d) or made under § 1.162-3T(d), as contained in 26 CFR part 1, revised as of April 1, 2013, 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 manner of electing and revoking the election to capitalize under this paragraph (d) or under § 1.162-3T(d), as contained in 26 CFR part 1, revised as of April 1, 2013, may be modified through guidance of general applicability (see §§ 601.601(d)(2) and 601.602 of this chapter). An election may not be made or revoked through the filing of an application for change in accounting method or, before obtaining the Commissioner's consent to make the late election or to revoke the election, by filing an amended Federal tax return.

(e) Optional method of accounting for rotable and temporary spare parts—(1) In general. This paragraph (e) provides an optional method of accounting for rotable and temporary spare parts (the optional method for rotable parts). A taxpayer may use the optional method for rotable parts, instead of the general rule under paragraph (a)(3) of this section, to account for its rotable and temporary spare parts as defined in paragraph (c)(2) of this section. A taxpayer that uses the optional method for rotable parts must use this method for all of its pools of rotable and temporary spare parts used in the same trade or business and for which it uses this method for its books and records. If a taxpayer uses the optional method for rotable parts for pools of rotable and temporary spare parts for which the taxpayer does not use the optional method for its books and records, then the taxpayer must use the optional method for all its pools in the same trade or business, whether rotable or temporary. The optional method for rotable parts is a method of accounting under section 446(a). Under the optional method for rotable parts, the taxpayer must apply the rules in this paragraph (e) to each rotable or temporary spare part (part) upon the taxpayer's initial installation, removal, repair, maintenance or improvement, reinstallation, and disposal of each part.

(2) Description of optional method for rotable parts—(i) Initial installation. The taxpayer must deduct the amount paid to acquire or produce the part in the taxable year that the part is first installed on a unit of property for use in the taxpayer's operations.

(ii) Removal from unit of property. In each taxable year in which the part is removed from a unit of property to which it was initially or subsequently installed, the taxpayer must—

(A) Include in gross income the fair market value of the part; and

(B) Include in the basis of the part the fair market value of the part included in income under paragraph (e)(2)(ii)(A) of this section and the amount paid to remove the part from the unit of property.

(iii) Repair, maintenance, or improvement of part. The taxpayer may not currently deduct and must include in the basis of the part any amounts paid to maintain, repair, or improve the part in the taxable year these amounts are paid.

(iv) Reinstallation of part. The taxpayer must deduct the amounts paid to reinstall the part and those amounts included in the basis of the part under paragraphs (e)(2)(ii)(B) and (e)(2)(iii) of this section, to the extent that those amounts have not been previously deducted under this paragraph (e)(2)(iv), in the taxable year that the part is reinstalled on a unit of property.

(v) Disposal of the part. The taxpayer must deduct the amounts included in the basis of the part under paragraphs (e)(2)(ii)(B) and (e)(2)(iii) of this section, to the extent that those amounts have not been previously deducted under paragraph (e)(2)(iv) of this section, in the taxable year in which the part is disposed of by the taxpayer.

(f) Application of de minimis safe harbor. If a taxpayer elects to apply the de minimis safe harbor under § 1.263(a)-1(f) to amounts paid for the production or acquisition of tangible property, then the taxpayer must apply the de minimis safe harbor to amounts paid for all materials and supplies that meet the requirements of § 1.263(a)-1(f), except for those materials and supplies that the taxpayer elects to capitalize and depreciate under paragraph (d) of this section or for which the taxpayer properly uses the optional method of accounting for rotable and temporary spare parts under paragraph (e) of this section. If the taxpayer properly applies the de minimis safe harbor under § 1.263(a)-1(f) to amounts paid for materials and supplies, then these amounts are not treated as amounts paid for materials and supplies under this section. See § 1.263(a)-1(f)(5) for the time and manner of electing the de minimis safe harbor and § 1.263(a)-1(f)(3)(iv) for the treatment of safe harbor amounts.

(g) Sale or disposition of materials and supplies. Upon sale or other disposition, materials and supplies as defined in this section are not treated as a capital asset under section 1221 or as property used in the trade or business under section 1231. Any asset for which the taxpayer makes the election to capitalize and depreciate under paragraph (d) of this section shall not be treated as a material or supply, and the recognition and character of the gain or loss for such depreciable asset are determined under other applicable provisions of the Code.

(h) Examples. The rules of this section are illustrated by the following examples, in which it is assumed, unless otherwise stated, that the property is not an incidental material or supply, that the taxpayer computes its income on a calendar year basis, that the taxpayer does not make the election to apply paragraph (d) of this section, or use the method of accounting described in paragraph (e) of this section, and that the taxpayer has not elected to apply the de minimis safe harbor under § 1.263(a)-1(f). The following examples illustrate only the application of this section and, unless otherwise stated, do not address the treatment under other provisions of the Code (for example, section 263A).

Example 1 Non-rotable components.

A owns a fleet of aircraft that it operates in its business. In Year 1, A purchases a stock of spare parts, which it uses to maintain and repair its aircraft. A keeps a record of consumption of these spare parts. In Year 2, A uses the spare parts for the repair and maintenance of one of its aircraft. Assume each aircraft is a unit of property under § 1.263(a)-3(e) and that spare parts are not rotable or temporary spare parts under paragraph (c)(2) of this section. Assume these repair and maintenance activities do not improve the aircraft under § 1.263(a)-3. These parts are materials and supplies under paragraph (c)(1)(i) of this section because they are components acquired and used to maintain and repair A's aircraft. Under paragraph (a)(1) of this section, the amounts that A paid for the spare parts in Year 1 are deductible in Year 2, the taxable year in which the spare parts are first used to repair and maintain the aircraft.

Example 2 Rotable spare parts; disposal method.

B operates a fleet of specialized vehicles that it uses in its service business. Assume that each vehicle is a unit of property under § 1.263(a)-3(e). At the time that it acquires a new type of vehicle, B also acquires a substantial number of rotable spare parts that it will keep on hand to quickly replace similar parts in B's vehicles as those parts break down or wear out. These rotable parts are removable from the vehicles and are repaired so that they can be reinstalled on the same or similar vehicles. In Year 1, B acquires several vehicles and a number of rotable spare parts to be used as replacement parts in these vehicles. In Year 2, B repairs several vehicles by using these rotable spare parts to replace worn or damaged parts. In Year 3, B removes these rotable spare parts from its vehicles, repairs the parts, and reinstalls them on other similar vehicles. In Year 5, B can no longer use the rotable parts it acquired in Year 1 and disposes of them as scrap. Assume that B does not improve any of the rotable spare parts under § 1.263(a)-3. Under paragraph (c)(1)(i) of this section, the rotable spare parts acquired in Year 1 are materials and supplies. Under paragraph (a)(3) of this section, rotable spare parts are generally used or consumed in the taxable year in which the taxpayer disposes of the parts. Therefore, under paragraph (a)(1) of this section, the amounts that B paid for the rotable spare parts in Year 1 are deductible in Year 5, the taxable year in which B disposes of the parts.

Example 3 Rotable spare parts; application of optional method of accounting.

C operates a fleet of specialized vehicles that it uses in its service business. Assume that each vehicle is a unit of property under § 1.263(a)-3(e). At the time that it acquires a new type of vehicle, C also acquires a substantial number of rotable spare parts that it will keep on hand to replace similar parts in C's vehicles as those parts break down or wear out. These rotable parts are removable from the vehicles and are repaired so that they can be reinstalled on the same or similar vehicles. C uses the optional method of accounting for all its rotable and temporary spare parts under paragraph (e) of this section. In Year 1, C acquires several vehicles and a number of rotable spare parts (the “Year 1 rotable parts”) to be used as replacement parts in these vehicles. In Year 2, C repairs several vehicles and uses the Year 1 rotable parts to replace worn or damaged parts. In Year 3, C pays amounts to remove these Year 1 rotable parts from its vehicles. In Year 4, C pays amounts to maintain, repair, or improve the Year 1 rotable parts. In Year 5, C pays amounts to reinstall the Year 1 rotable parts on other similar vehicles. In Year 8, C removes the Year 1 rotable parts from these vehicles and stores these parts for possible later use. In Year 9, C disposes of the Year 1 rotable parts. Under paragraph (e) of this section, C must deduct the amounts paid to acquire and install the Year 1 rotable parts in Year 2, the taxable year in which the rotable parts are first installed by C in C's vehicles. In Year 3, when C removes the Year 1 rotable parts from its vehicles, C must include in its gross income the fair market value of each part. Also, in Year 3, C must include in the basis of each Year 1 rotable part the fair market value of the rotable part and the amount paid to remove the rotable part from the vehicle. In Year 4, C must include in the basis of each Year 1 rotable part the amounts paid to maintain, repair, or improve each rotable part. In Year 5, the year that C reinstalls the Year 1 rotable parts (as repaired or improved) in other vehicles, C must deduct the reinstallation costs and the amounts previously included in the basis of each part. In Year 8, the year that C removes the Year 1 rotable parts from the vehicles, C must include in income the fair market value of each rotable part removed. In addition, in Year 8, C must include in the basis of each part the fair market value of that part and the amount paid to remove each rotable part from the vehicle. In Year 9, the year that C disposes of the Year 1 rotable parts, C may deduct the amounts remaining in the basis of each rotable part.

Example 4 Rotable part acquired as part of a single unit of property; not material or supply.

D operates a fleet of aircraft. In Year 1, D acquires a new aircraft, which includes two new aircraft engines. The aircraft costs $500,000 and has an economic useful life of more than 12 months, beginning when it is placed in service. In Year 5, after the aircraft is operated for several years in D's business, D removes the engines from the aircraft, repairs or improves the engines, and either reinstalls the engines on a similar aircraft or stores the engines for later reinstallation. Assume the aircraft purchased in Year 1, including its two engines, is a unit of property under § 1.263(a)-3(e). Because the engines were acquired as part of the aircraft, a single unit of property, the engines are not materials or supplies under paragraph (c)(1)(i) of this section nor rotable or temporary spare parts under paragraph (c)(2) of this section. Accordingly, D may not apply the rules of this section to the aircraft engines upon the original acquisition of the aircraft nor after the removal of the engines from the aircraft for use in the same or similar aircraft. Rather, D must apply the rules under §§ 1.263(a)-2 and 1.263(a)-3 to the aircraft, including its engines, to determine the treatment of amounts paid to acquire, produce, or improve the unit of property.

Example 5 Consumable property.

E operates a fleet of aircraft that carries freight for its customers. E has several storage tanks on its premises, which hold jet fuel for its aircraft. Assume that once the jet fuel is placed in E's aircraft, the jet fuel is reasonably expected to be consumed within 12 months or less. On December 31, Year 1, E purchases a two-year supply of jet fuel. In Year 2, E uses a portion of the jet fuel purchased on December 31, Year 1, to fuel the aircraft used in its business. The jet fuel that E purchased in Year 1 is a material or supply under paragraph (c)(1)(ii) of this section because it is reasonably expected to be consumed within 12 months or less from the time it is placed in E's aircraft. Under paragraph (a)(1) of this section, E may deduct in Year 2 the amounts paid for the portion of jet fuel used in the operation of E's aircraft in Year 2.

Example 6 Unit of property that costs $200 or less.

F operates a business that rents out a variety of small individual items to customers (rental items). F maintains a supply of rental items on hand. In Year 1, F purchases a large quantity of rental items to use in its rental business. Assume that each rental item is a unit of property under § 1.263(a)-3(e) and costs $200 or less. In Year 2, F begins using all the rental items purchased in Year 1 by providing them to customers of its rental business. F does not sell or exchange these items on established retail markets at any time after the items are used in the rental business. The rental items are materials and supplies under paragraph (c)(1)(iv) of this section. Under paragraph (a)(1) of this section, the amounts that F paid for the rental items in Year 1 are deductible in Year 2, the taxable year in which the rental items are first used in F's business.

Example 7 Unit of property that costs $200 or less.

G provides billing services to its customers. In Year 1, G pays amounts to purchase 50 scanners to be used by its employees. Assume each scanner is a unit of property under § 1.263(a)-3(e) and costs less than $200. In Year 1, G's employees begin using 35 of the scanners, and F stores the remaining 15 scanners for use in a later taxable year. The scanners are materials and supplies under paragraph (c)(1)(iv) of this section. Under paragraph (a)(1) of this section, the amounts G paid for 35 of the scanners are deductible in Year 1, the taxable year in which G first uses each of those scanners. The amounts that G paid for each of the remaining 15 scanners are deductible in the taxable year in which each machine is first used in G's business.

Example 8 Materials and supplies that cost less than $200; de minimis safe harbor.

Assume the same facts as in Example 7 except that G's scanners qualify for the de minimis safe harbor under § 1.263(a)-1(f), and G properly elects to apply the de minimis safe harbor under § 1.263(a)-1(f) to amounts paid in Year 1. G must apply the de minimis safe harbor under § 1.263(a)-1(f) to amounts paid for the scanners, rather than treat these amounts as costs of materials and supplies under this section. In accordance with § 1.263(a)-1(f)(3)(iv), G may deduct the amounts paid for all 50 scanners under § 1.162-1 in the taxable year the amounts are paid.

Example 9 Unit of property that costs $200 or less; bulk purchase.

H provides consulting services to its customers. In Year 1, H pays $500 to purchase one box of 10 toner cartridges to use as needed for H's printers. Assume each toner cartridge is a unit of property under § 1.263(a)-3(e). In Year 1, H's employees place 8 of the toner cartridges in printers in H's office, and store the remaining 2 cartridges for use in a later taxable year. The toner cartridges are materials and supplies under paragraph (c)(1)(iv) of this section because even though purchased in one box costing more than $200, the allocable cost of each unit of property equals $50. Therefore, under paragraph (a)(1) of this section, the $400 paid by H for 8 of the cartridges is deductible in Year 1, the taxable year in which H first uses each of those cartridges. The amounts paid by H for each of the remaining 2 cartridges ($50 each) are deductible in the taxable year in which each cartridge is first used in H's business.

Example 10 Materials and supplies used in improvements; coordination with § 1.263(a)-3.

J owns various machines that are used in its business. Assume that each machine is a unit of property under § 1.263(a)-3(e). In Year 1, J purchases a supply of spare parts for its machines. J acquired the parts to use in the repair or maintenance of the machines under § 1.162-4 or in the improvement of the machines under § 1.263(a)-3. The spare parts are not rotable or temporary spare parts under paragraph (c)(2) of this section. In Year 2, J uses all of these spare parts in an activity that improves a machine under § 1.263(a)-3. Under paragraph (c)(1)(i) of this section, the spare parts purchased by J in Year 1 are materials and supplies. Under paragraph (a)(1) of this section, the amounts paid for the spare parts are otherwise deductible as materials and supplies in Year 2, the taxable year in which J uses those parts. However, because these materials and supplies are used to improve J's machine, J is required to capitalize the amounts paid for those spare parts under § 1.263(a)-3.

Example 11 Cost of producing materials and supplies; coordination with section 263A.

K is a manufacturer that produces liquid waste as part of its operations. K determines that its current liquid waste disposal process is inadequate. To remedy the problem, in Year 1, K constructs a leaching pit to provide a draining area for the liquid waste. Assume the leaching pit is a unit of property under § 1.263(a)-3(e) and has an economic useful life of 12 months or less, starting on the date that K begins to use the leaching pit as a draining area. At the end of this period, K's factory will be connected to the local sewer system. In Year 2, K starts using the leaching pit in its operations. The amounts paid to construct the leaching pit (including the direct and allocable indirect costs of property produced under section 263A) are amounts paid for a material or supply under paragraph (c)(1)(iii) of this section. However, the amounts paid to construct the leaching pit may be subject to capitalization under section 263A if these amounts comprise the direct or allocable indirect costs of property produced by K.

Example 12 Costs of acquiring materials and supplies for production of property; coordination with section 263A.

In Year 1, L purchases jigs, dies, molds, and patterns for use in the manufacture of L's products. Assume each jig, die, mold, and pattern is a unit of property under § 1.263(a)-3(e). The economic useful life of each jig, die, mold, and pattern is 12 months or less, beginning when each item is used in the manufacturing process. The jigs, dies, molds, and patterns are not components acquired to maintain, repair, or improve any of L's equipment under paragraph (c)(1)(i) of this section. L begins using the jigs, dies, molds and patterns in Year 2 to manufacture its products. These items are materials and supplies under paragraph (c)(1)(iii) of this section. Under paragraph (a)(1) of this section, the amounts paid for the items are otherwise deductible in Year 2, the taxable year in which L first uses those items. However, the amounts paid for these materials and supplies may be subject to capitalization under section 263A if these amounts comprise the direct or allocable indirect costs of property produced by L.

Example 13 Election to capitalize and depreciate.

M is in the mining business. M acquires certain temporary spare parts, which it keeps on hand to avoid operational time loss in the event it must make temporary repairs to a unit of property that is subject to depreciation. These parts are not used to improve property under § 1.263(a)-3(d). These temporary spare parts are used until a new or repaired part can be installed and then are removed and stored for later temporary installation. M does not use the optional method of accounting for rotable and temporary spare parts in paragraph (e) of this section for any of its rotable or temporary spare parts. The temporary spare parts are materials and supplies under paragraph (c)(1)(i) of this section. Under paragraphs (a)(1) and (a)(3) of this section, the amounts paid for the temporary spare parts are deductible in the taxable year in which they are disposed of by M. However, because it is unlikely that the temporary spare parts will be disposed of in the near future, M would prefer to treat the amounts paid for the spare parts as capital expenditures subject to depreciation. M may elect under paragraph (d) of this section to treat the cost of each temporary spare part as a capital expenditure and as an asset subject to an allowance for depreciation. M makes this election by capitalizing the amounts paid for each spare part in the taxable year that M acquires the spare parts and by beginning to recover the costs of each part on its timely filed Federal tax return for the taxable year in which the part is placed in service for purposes of determining depreciation under the applicable provisions of the Internal Revenue Code and the Treasury Regulations. See § 1.263(a)-2(g) for the treatment of capital expenditures.

Example 14 Election to apply de minimis safe harbor.

(i) N provides consulting services to its customers. In Year 1, N pays amounts to purchase 50 laptop computers. Each laptop computer is a unit of property under § 1.263(a)-3(e), costs $400, and has an economic useful life of more than 12 months. Also in Year 1, N purchases 50 office chairs to be used by its employees. Each office chair is a unit of property that costs $100. N has an applicable financial statement (as defined in § 1.263(a)-1(f)(4)) and N has a written accounting policy at the beginning Year 1 to expense amounts paid for units of property costing $500 or less. N treats amounts paid for property costing $500 or less as an expense on its applicable financial statement in Year 1.

(ii) The laptop computers are not materials or supplies under paragraph (c) of this section. Therefore, the amounts N pays for the computers must generally be capitalized under § 1.263(a)-2(d) as amounts paid for the acquisition of tangible property. The office chairs are materials and supplies under paragraph (c)(1)(iv) of this section. Thus, under paragraph (a)(1) of this section, the amounts paid for the office chairs are deductible in the taxable year in which they are first used in N's business. However, under paragraph (f) of this section, if N properly elects to apply the de minimis safe harbor under § 1.263(a)-1(f) to amounts paid in Year 1, then N must apply the de minimis safe harbor under § 1.263(a)-1(f) to amounts paid for the computers and the office chairs, rather than treat the office chairs as the costs of materials and supplies under § 1.162-3. Under the de minimis safe harbor, N may not capitalize the amounts paid for the computers under § 1.263(a)-2 nor treat the office chairs as materials and supplies under § 1.162-3. Instead, in accordance with § 1.263(a)-1(f)(3)(iv), under § 1.162-1, N may deduct the amounts paid for the computers and the office chairs in the taxable year paid.

(i) 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.

(j) Effective/applicability date—(1) In general. This section generally applies to amounts paid or incurred in taxable years beginning on or after January 1, 2014. However, a taxpayer may apply paragraph (e) of this section (the optional method of accounting for rotable and temporary spare parts) to taxable years beginning on or after January 1, 2014. Except as provided in paragraphs (j)(2) and (j)(3) of this section, § 1.162-3 as contained in 26 CFR part 1 edition revised as of April 1, 2011, applies to taxable years beginning before January 1, 2014.

(2) Early application of this section—(i) In general. Except for paragraph (e) of this section, a taxpayer may choose to apply this section to amounts paid or incurred in taxable years beginning on or after January 1, 2012. A taxpayer may choose to apply paragraph (e) of this section (the optional method of accounting for rotable and temporary spare parts) to taxable years beginning on or after January 1, 2012.

(ii) Transition rule for election to capitalize materials and supplies on 2012 and 2013 returns. If under paragraph (j)(2)(i) of this section, a taxpayer chooses to make the election to capitalize and depreciate certain materials and supplies under paragraph (d) of this section for its 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)(3) of this section on its timely filed original Federal tax return for the applicable taxable year, the taxpayer must make the election specified in paragraph (d)(3) of this section for the applicable taxable year by filing 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.

(3) Optional application of TD 9564. Except for § 1.162-3T(e), a taxpayer may choose to apply § 1.162-3T as contained in TD 9564 (76 FR 81060) December 27, 2011, to amounts paid or incurred (to acquire or produce property) in taxable years beginning on or after January 1, 2012, and before January 1, 2014. In applying § 1.162-3T(d)(3), as contained in 26 CFR part 1, revised as of April 1, 2013, a taxpayer makes the election under § 1.162-3T(d) by capitalizing the amounts paid to acquire or produce a material or supply in the taxable year the amounts are paid and by beginning to depreciate the costs when the asset is placed in service by the taxpayer for purposes of determining depreciation under the applicable provisions of the Internal Revenue Code and the Treasury Regulations. The election under § 1.162-3T(d), as contained in 26 CFR part 1, revised as of April 1, 2013, does not apply to an asset or a portion thereof placed in service and disposed of in the same taxable year. A taxpayer may choose to apply § 1.162-3T(e) (the optional method of accounting for rotable and temporary spare parts) as contained in TD 9564 (76 FR 81060) December 27, 2011, to taxable years beginning on or after January 1, 2012, and before January 1, 2014.
