26 C.F.R. § 1.162-3
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.
