a calendar-year taxpayer, purchases a house in 1985 that she occupies as her principal residence. In February 2004, A ceases to occupy the house and converts it to residential rental property. At the time of the conversion to residential rental property, the house's fair market value (excluding land) is $130,000 and adjusted depreciable basis attributable to the house (excluding land) is $150,000. Pursuant to this paragraph (b), A is considered to have placed in service residential rental property in February 2004 with a depreciable basis of $130,000. A depreciates the residential rental property under the general depreciation system by using the straight-line method, a 27.5-year recovery period, and the mid-month convention. Pursuant to §§ 1.168(k)-1T(f)(6)(iii)(B) or 1.1400L(b)-1T(f)(6), this property is not eligible for the additional first year depreciation deduction provided by section 168(k) or section 1400L(b). Thus, the depreciation allowance for the house for 2004 is $4,137, after taking into account the mid-month convention (($130,000 adjusted depreciable basis multiplied by the applicable depreciation rate of 3.636% (1/27.5)) multiplied by the mid-month convention fraction of 10.5/12). The amount of depreciation computed under section 168, however, may be limited under other provisions of the Internal Revenue Code, such as, section 280A.
(i) X, a calendar-year corporation, places in service in 1999 equipment at a cost of $100,000 and uses this equipment from 1999 through 2003 primarily in its A business. X depreciates the equipment for 1999 through 2003 under the general depreciation system as 7-year property by using the 200-percent declining balance method (which switched to the straight-line method in 2003), a 7-year recovery period, and a half-year convention. Beginning in 2004, X primarily uses the equipment in its B business. As a result, the classification of the equipment under section 168(e) changes from 7-year property to 5-year property and the recovery period of the equipment under the general depreciation system changes from 7 years to 5 years. The depreciation method does not change. On January 1, 2004, the adjusted depreciable basis of the equipment is $22,311. X depreciates its 5-year recovery property placed in service in 2004 under the general depreciation system by using the 200-percent declining balance method and a 5-year recovery period. X does not use the optional depreciation tables.
(ii) Under paragraph (d)(3)(i) of this section, X's allowable depreciation deduction for the equipment for 2004 and subsequent taxable years is determined as though X placed the equipment in service in 2004 for use primarily in its B business. The depreciable basis of the equipment as of January 1, 2004, is $22,311 (the adjusted depreciable basis at January 1, 2004). Because X does not use the optional depreciation tables, the depreciation allowance for 2004 (the deemed placed-in-service year) for this equipment only is computed without taking into account the half-year convention. Pursuant to paragraph (d)(3)(i)(C) of this section, this equipment is not eligible for the additional first year depreciation deduction provided by section 168(k) or section 1400L(b). Thus, X's allowable depreciation deduction for the equipment for 2004 is $8,924 ($22,311 adjusted depreciable basis at January 1, 2004, multiplied by the applicable depreciation rate of 40% (200/5)). X's allowable depreciation deduction for the equipment for 2005 is $5,355 ($13,387 adjusted depreciable basis at January 1, 2005, multiplied by the applicable depreciation rate of 40% (200/5)).
(iii) Alternatively, under paragraph (d)(3)(ii) of this section, X may elect to disregard the change in the use and, as a result, may continue to treat the equipment as though it is used primarily in its A business. If the election is made, X's allowable depreciation deduction for the equipment for 2004 is $8,924 ($22,311 adjusted depreciable basis at January 1, 2004, multiplied by the applicable depreciation rate of 40% (1/2.5 years remaining at January 1, 2004)). X's allowable depreciation deduction for the equipment for 2005 is $8,925 ($13,387 adjusted depreciable basis at January 1, 2005, multiplied by the applicable depreciation rate of 66.67% (1/1.5 years remaining at January 1, 2005)).
(i) Same facts as in Example 1, except that X used the optional depreciation tables for computing depreciation for 1999 through 2003. Pursuant to paragraph (d)(5) of this section, X chooses to continue to use the optional depreciation table for the equipment. X does not make the election provided in paragraph (d)(3)(ii) of this section to disregard the change in use.
(ii) In accordance with paragraph (d)(5)(ii)(A) of this section, X must first identify the appropriate optional depreciation table for the equipment. This table is table 1 in Rev. Proc. 87-57 because the equipment will be depreciated in the year of change (2004) under the general depreciation system using the 200-percent declining balance method, a 5-year recovery period, and the half-year convention (which is the convention that applied to the equipment in 1999). Pursuant to paragraph (d)(3)(i)(C) of this section, this equipment is not eligible for the additional first year depreciation deduction provided by section 168(k) or section 1400L(b). For 2004, X multiplies its adjusted depreciable basis in the equipment as of January 1, 2004, of $22,311, by the annual depreciation rate in table 1 for recovery year 1 for a 5-year recovery period (.20), to determine the depreciation allowance of $4,462. For 2005, X multiplies its adjusted depreciable basis in the equipment as of January 1, 2004, of $22,311, by the annual depreciation rate in table 1 for recovery year 2 for a 5-year recovery period (.32), to determine the depreciation allowance of $7,140.
(i) Y, a calendar-year corporation, places in service in January 2002, equipment at a cost of $100,000 and uses this equipment in 2002 and 2003 only within the United States. Y elects not to deduct the additional first year depreciation under section 168(k). Y depreciates the equipment for 2002 and 2003 under the general depreciation system by using the 200-percent declining balance method, a 5-year recovery period, and a half-year convention. Beginning in 2004, Y uses the equipment predominantly outside the United States. As a result of this change in the use, the equipment is subject to the alternative depreciation system beginning in 2004. Under the alternative depreciation system, the equipment is depreciated by using the straight line method and a 9-year recovery period. The adjusted depreciable basis of the equipment at January 1, 2004, is $48,000.
(ii) Pursuant to paragraph (d)(4) of this section, Y's allowable depreciation deduction for 2004 and subsequent taxable years is determined as though the equipment had been placed in service in January 2002, as property used predominantly outside the United States. Further, pursuant to paragraph (d)(4)(i) of this section, the equipment is not eligible in 2004 for the additional first year depreciation deduction provided by section 168(k) or section 1400L(b). In determining the applicable depreciation rate for 2004, the applicable depreciation method is the straight line method and the applicable recovery period is 7.5 years, which is the number of years remaining at January 1, 2004, for property placed in service in 2002 with a 9-year recovery period (taking into account the half-year convention). Thus, the depreciation allowance for 2004 is $6,398 ($48,000 adjusted depreciable basis at January 1, 2004, multiplied by the applicable depreciation rate of 13.33% (1/7.5 years)). The depreciation allowance for 2005 is $6,398 ($41,602 adjusted depreciable basis at January 1, 2005, multiplied by the applicable depreciation rate of 15.38% (1/6.5 years remaining at January 1, 2005)).
(i) Same facts as in Example 3, except that Y used the optional depreciation tables for computing depreciation in 2002 and 2003. Pursuant to paragraph (d)(5) of this section, Y chooses to continue to use the optional depreciation table for the equipment. Further, pursuant to paragraph (d)(4)(i) of this section, the equipment is not eligible in 2004 for the additional first year depreciation deduction provided by section 168(k) or section 1400L(b).
(ii) In accordance with paragraph (d)(5)(ii)(B) of this section, Y must first determine the appropriate optional depreciation table for the equipment pursuant to paragraph (d)(5)(ii)(B)(1) of this section. This table is table 8 in Rev. Proc. 87-57, which corresponds to the alternative depreciation system, the straight line method, a 9-year recovery period, and the half-year convention (because Y depreciated 5-year property in 2002 using a half-year convention). Next, Y must determine the appropriate recovery year in table 8. Because the year of change is 2004, the depreciation allowance for the equipment for 2004 is determined using recovery year 3 of table 8. For 2004, Y multiplies its adjusted depreciable basis in the equipment as of January 1, 2004, of $48,000, by the product of the annual depreciation rate in table 8 for recovery year 3 for a 9-year recovery period (.1111) and the transaction coefficient of 1.200 [1/(1−(.0556 (table 8 for recovery year 1 for a 9-year recovery period) + .1111 (table 8 for recovery year 2 for a 9-year recovery period)))], to determine the depreciation allowance of $6,399. For 2005, Y multiplies its adjusted depreciable basis in the equipment as of January 1, 2004, of $48,000, by the product of the annual depreciation rate in table 8 for recovery year 4 for a 9-year recovery period (.1111) and the transaction coefficient (1.200), to determine the depreciation allowance of $6,399.
(i) Z, a utility and calendar-year corporation, acquires and places in service on January 1, 2004, equipment at a cost of $100,000. Z uses this equipment in its combustion turbine production plant for 4 months and then uses the equipment in its steam production plant for the remainder of 2004. Z's combustion turbine production plant assets are classified as 15-year property and are depreciated by Z under the general depreciation system using a 15-year recovery period and the 150-percent declining balance method of depreciation. Z's steam production plant assets are classified as 20-year property and are depreciated by Z under the general depreciation system using a 20-year recovery period and the 150-percent declining balance method of depreciation. Z uses the optional depreciation tables. The equipment is 50-percent bonus depreciation property for purposes of section 168(k).
(ii) Pursuant to this paragraph (e), Z must determine depreciation based on the primary use of the equipment during the placed-in-service year. Z has consistently determined the primary use of all of its MACRS properties by comparing the number of full months in the taxable year during which a MACRS property is used in one manner with the number of full months in that taxable year during which that MACRS property is used in another manner. Applying this approach, Z determines the depreciation allowance for the equipment for 2004 is based on the equipment being classified as 20-year property because the equipment was used by Z in its steam production plant for 8 months in 2004. If the half-year convention applies in 2004, the appropriate optional depreciation table is table 1 in Rev. Proc. 87-57, which is the table for MACRS property subject to the general depreciation system, the 150-percent declining balance method, a 20-year recovery period, and the half-year convention. Thus, the depreciation allowance for the equipment for 2004 is $51,875, which is the total of $50,000 for the 50-percent additional first year depreciation deduction allowable (the unadjusted depreciable basis of $100,000 multiplied by .50), plus $1,875 for the 2004 depreciation allowance on the remaining adjusted depreciable basis of $50,000 [(the unadjusted depreciable basis of $100,000 less the additional first year depreciation deduction of $50,000) multiplied by the annual depreciation rate of .0375 in table 1 for recovery year 1 for a 20-year recovery period].
, a calendar year corporation, places in service on January 1, 2004, several computers at a total cost of $100,000. T uses these computers within the United States for 3 months in 2004 and then moves and uses the computers outside the United States for the remainder of 2004. Pursuant to § 1.48-1(g)(1)(i), the computers are considered as used predominantly outside the United States in 2004. As a result, for 2004, the computers are required to be depreciated under the alternative depreciation system of section 168(g) with a recovery period of 5 years pursuant to section 168(g)(3)(C). T uses the optional depreciation tables. If the half-year convention applies in 2004, the appropriate optional depreciation table is table 8 in Rev. Proc. 87-57, which is the table for MACRS property subject to the alternative depreciation system, the straight line method, a 5-year recovery period, and the half-year convention. Thus, the depreciation allowance for the computers for 2004 is $10,000, which is equal to the unadjusted depreciable basis of $100,000 multiplied by the annual depreciation rate of .10 in table 8 for recovery year 1 for a 5-year recovery period. Because the computers are required to be depreciated under the alternative depreciation system in their placed-in-service year, pursuant to section 168(k)(2)(C)(i) and § 1.168(k)-1T(b)(2)(ii), the computers are not eligible for the additional first year depreciation deduction provided by section 168(k).
