§ 1.168(i)-4 — (i)-4 Changes In Use

26 C.F.R. § 1.168(i)-4

View:

(a) Scope. This section provides the rules for determining the depreciation allowance for MACRS property (as defined in § 1.168(b)-1T(a)(2)) for which the use changes in the hands of the same taxpayer (change in the use). The allowance for depreciation under this section constitutes the amount of depreciation allowable under section 167(a) for the year of change and any subsequent taxable year. For purposes of this section, the year of change is the taxable year in which a change in the use occurs.

(b) Conversion to business or income-producing use—(1) Depreciation deduction allowable. This paragraph (b) applies to property that is converted from personal use to use in a taxpayer's trade or business, or for the production of income, during a taxable year. This conversion includes property that was previously used by the taxpayer for personal purposes, including real property (other than land) that is acquired before 1987 and converted from personal use to business or income-producing use after 1986, and depreciable property that was previously used by a tax-exempt entity before the entity changed to a taxable entity. Except as otherwise provided by the Internal Revenue Code or regulations under the Internal Revenue Code, upon a conversion to business or income-producing use, the depreciation allowance for the year of change and any subsequent taxable year is determined as though the property is placed in service by the taxpayer on the date on which the conversion occurs. Thus, except as otherwise provided by the Internal Revenue Code or regulations under the Internal Revenue Code, the taxpayer must use any applicable depreciation method, recovery period, and convention prescribed under section 168 for the property in the year of change, consistent with any election made under section 168 by the taxpayer for that year (see, for example, section 168(b)(5)). See §§ 1.168(k)-1(f)(6)(iii) or 1.168(k)-2(g)(6)(iii), as applicable, and 1.1400L(b)-1(f)(6) for the additional first year depreciation deduction rules applicable to a conversion to business or income-producing use. The depreciable basis of the property for the year of change is the lesser of its fair market value or its adjusted depreciable basis (as defined in § 1.168(b)-1T(a)(4)), as applicable, at the time of the conversion to business or income-producing use.

(2) Example. The application of this paragraph (b) is illustrated by the following example:

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.

(c) Conversion to personal use. The conversion of MACRS property from business or income-producing use to personal use during a taxable year is treated as a disposition of the property in that taxable year. The depreciation allowance for MACRS property for the year of change in which the property is treated as being disposed of is determined by first multiplying the adjusted depreciable basis of the property as of the first day of the year of change by the applicable depreciation rate for that taxable year (for further guidance, for example, see section 6 of Rev. Proc. 87-57 (1987-2 C. B. 687, 692) (see § 601.601(d)(2)(ii)(b) of this chapter)). This amount is then multiplied by a fraction, the numerator of which is the number of months (including fractions of months) the property is deemed to be placed in service during the year of change (taking into account the applicable convention) and the denominator of which is 12. No depreciation deduction is allowable for MACRS property placed in service and disposed of in the same taxable year. See §§ 1.168(k)-1(f)(6)(ii)or 1.168(k)-2(g)(6)(ii), as applicable, and 1.1400L(b)-1(f)(6) for the additional first year depreciation deduction rules applicable to property placed in service and converted to personal use in the same taxable year. Upon the conversion to personal use, no gain, loss, or depreciation recapture under section 1245 or section 1250 is recognized. However, the provisions of section 1245 or section 1250 apply to any disposition of the converted property by the taxpayer at a later date. For listed property (as defined in section 280F(d)(4)), see section 280F(b)(2) for the recapture of excess depreciation upon the conversion to personal use.

(d) Change in the use results in a different recovery period and/or depreciation method—(1) In general. This paragraph (d) applies to a change in the use of MACRS property during a taxable year subsequent to the placed-in-service year, if the property continues to be MACRS property owned by the same taxpayer and, as a result of the change in the use, has a different recovery period, a different depreciation method, or both. For example, this paragraph (d) applies to MACRS property that—

(i) Begins or ceases to be used predominantly outside the United States;

(ii) Results in a reclassification of the property under section 168(e) due to a change in the use of the property; or

(iii) Begins or ceases to be tax-exempt use property (as defined in section 168(h)).

(2) Determination of change in the use—(i) In general. Except as provided in paragraph (d)(2)(ii) of this section, a change in the use of MACRS property occurs when the primary use of the MACRS property in the taxable year is different from its primary use in the immediately preceding taxable year. The primary use of MACRS property may be determined in any reasonable manner that is consistently applied to the taxpayer's MACRS property.

(ii) Alternative depreciation system property—(A) Property used within or outside the United States. A change in the use of MACRS property occurs when a taxpayer begins or ceases to use MACRS property predominantly outside the United States during the taxable year. The determination of whether MACRS property is used predominantly outside the United States is made in accordance with the test in § 1.48-1(g)(1)(i) for determining predominant use.

(B) Tax-exempt bond financed property. A change in the use of MACRS property occurs when the property changes to tax-exempt bond financed property, as described in section 168(g)(1)(C) and (g)(5), during the taxable year. For purposes of this paragraph (d), MACRS property changes to tax-exempt bond financed property when a tax-exempt bond is first issued after the MACRS property is placed in service. MACRS property continues to be tax-exempt bond financed property in the hands of the taxpayer even if the tax-exempt bond (including any refunding issue) is no longer outstanding or is redeemed.

(C) Other mandatory alternative depreciation system property. A change in the use of MACRS property occurs when the property changes to, or changes from, property described in section 168(g)(1)(B) (tax-exempt use property) or (D) (imported property covered by an Executive order) during the taxable year.

(iii) Change in the use deemed to occur on first day of the year of change. If a change in the use of MACRS property occurs under this paragraph (d)(2), the depreciation allowance for that MACRS property for the year of change is determined as though the use of the MACRS property changed on the first day of the year of change.

(3) Change in the use results in a shorter recovery period and/or a more accelerated depreciation method—(i) Treated as placed in service in the year of change—(A) In general. If a change in the use results in the MACRS property changing to a shorter recovery period and/or a depreciation method that is more accelerated than the method used for the MACRS property before the change in the use, the depreciation allowances beginning in the year of change are determined as though the MACRS property is placed in service by the taxpayer in the year of change.

(B) Computation of depreciation allowance. The depreciation allowances for the MACRS property for any 12-month taxable year beginning with the year of change are determined by multiplying the adjusted depreciable basis of the MACRS property as of the first day of each taxable year by the applicable depreciation rate for each taxable year. In determining the applicable depreciation rate for the year of change and subsequent taxable years, the taxpayer must use any applicable depreciation method and recovery period prescribed under section 168 for the MACRS property in the year of change, consistent with any election made under section 168 by the taxpayer for that year (see, for example, section 168(b)(5)). If there is a change in the use of MACRS property, the applicable convention that applies to the MACRS property is the same as the convention that applied before the change in the use of the MACRS property. However, the depreciation allowance for the year of change for the MACRS property is determined without applying the applicable convention, unless the MACRS property is disposed of during the year of change. See paragraph (d)(5) of this section for the rules relating to the computation of the depreciation allowance under the optional depreciation tables. If the year of change or any subsequent taxable year is less than 12 months, the depreciation allowance determined under this paragraph (d)(3)(i) must be adjusted for a short taxable year (for further guidance, for example, see Rev. Proc. 89-15 (1989-1 C.B. 816) (see § 601.601(d)(2)(ii)(b) of this chapter)).

(C) Special rules. MACRS property affected by this paragraph (d)(3)(i) is not eligible in the year of change for the election provided under section 168(f)(1), 179, or 1400L(f), or for the additional first year depreciation deduction provided in section 168(k) or 1400L(b). See §§ 1.168(k)-1(f)(6)(iv) or 1.168(k)-2(g)(6)(iv), as applicable, and 1.1400L(b)-1(f)(6) for other additional first year depreciation deduction rules applicable to a change in the use of MACRS property subsequent to its placed-in-service year. For purposes of determining whether the mid-quarter convention applies to other MACRS property placed in service during the year of change, the unadjusted depreciable basis (as defined in § 1.168(b)-1T(a)(3)) or the adjusted depreciable basis of MACRS property affected by this paragraph (d)(3)(i) is not taken into account.

(ii) Option to disregard the change in the use. In lieu of applying paragraph (d)(3)(i) of this section, the taxpayer may elect to determine the depreciation allowance as though the change in the use had not occurred. The taxpayer elects this option by claiming on the taxpayer's timely filed (including extensions) Federal income tax return for the year of change the depreciation allowance for the property as though the change in the use had not occurred. See paragraph (g)(2) of this section for the manner for revoking this election.

(4) Change in the use results in a longer recovery period and/or a slower depreciation method—(i) Treated as originally placed in service with longer recovery period and/or slower depreciation method. If a change in the use results in a longer recovery period and/or a depreciation method for the MACRS property that is less accelerated than the method used for the MACRS property before the change in the use, the depreciation allowances beginning with the year of change are determined as though the MACRS property had been originally placed in service by the taxpayer with the longer recovery period and/or the slower depreciation method. MACRS property affected by this paragraph (d)(4) is not eligible in the year of change for the election provided under section 168(f)(1), 179, or 1400L(f), or for the additional first year depreciation deduction provided in section 168(k) or 1400L(b). See §§ 1.168(k)-1(f)(6)(iv) or 1.168(k)-2(g)(6)(iv), as applicable, and 1.1400L(b)-1(f)(6) for other additional first year depreciation deduction rules applicable to a change in the use of MACRS property subsequent to its placed-in-service year.

(ii) Computation of the depreciation allowance. The depreciation allowances for the MACRS property for any 12-month taxable year beginning with the year of change are determined by multiplying the adjusted depreciable basis of the MACRS property as of the first day of each taxable year by the applicable depreciation rate for each taxable year. If there is a change in the use of MACRS property, the applicable convention that applies to the MACRS property is the same as the convention that applied before the change in the use of the MACRS property. If the year of change or any subsequent taxable year is less than 12 months, the depreciation allowance determined under this paragraph (d)(4)(ii) must be adjusted for a short taxable year (for further guidance, for example, see Rev. Proc. 89-15 (1989-1 C.B. 816) (see § 601.601(d)(2)(ii)(b) of this chapter)). See paragraph (d)(5) of this section for the rules relating to the computation of the depreciation allowance under the optional depreciation tables. In determining the applicable depreciation rate for the year of change and any subsequent taxable year—

(A) The applicable depreciation method is the depreciation method that would apply in the year of change and any subsequent taxable year for the MACRS property had the taxpayer used the longer recovery period and/or the slower depreciation method in the placed-in-service year of the property. If the 200-or 150-percent declining balance method would have applied in the placed-in-service year but the method would have switched to the straight line method in the year of change or any prior taxable year, the applicable depreciation method beginning with the year of change is the straight line method; and

(B) The applicable recovery period is either—

(1) The longer recovery period resulting from the change in the use if the applicable depreciation method is the 200-or 150-percent declining balance method (as determined under paragraph (d)(4)(ii)(A) of this section) unless the recovery period did not change as a result of the change in the use, in which case the applicable recovery period is the same recovery period that applied before the change in the use; or

(2) The number of years remaining as of the beginning of each taxable year (taking into account the applicable convention) had the taxpayer used the longer recovery period in the placed-in-service year of the property if the applicable depreciation method is the straight line method (as determined under paragraph (d)(4)(ii)(A) of this section) unless the recovery period did not change as a result of the change in the use, in which case the applicable recovery period is the number of years remaining as of the beginning of each taxable year (taking into account the applicable convention) based on the recovery period that applied before the change in the use.

(5) Using optional depreciation tables—(i) Taxpayer not bound by prior use of table. If a taxpayer used an optional depreciation table for the MACRS property before a change in the use, the taxpayer is not bound to use the appropriate new table for that MACRS property beginning in the year of change (for further guidance, for example, see section 8 of Rev. Proc. 87-57 (1987-2 C.B. 687, 693) (see § 601.601(d)(2)(ii)(b) of this chapter)). If a taxpayer did not use an optional depreciation table for MACRS property before a change in the use and the change in the use results in a shorter recovery period and/or a more accelerated depreciation method (as described in paragraph (d)(3)(i) of this section), the taxpayer may use the appropriate new table for that MACRS property beginning in the year of change. If a taxpayer chooses not to use the optional depreciation table, the depreciation allowances for the MACRS property beginning in the year of change are determined under paragraph (d)(3)(i) or (4) of this section, as applicable.

(ii) Taxpayer chooses to use optional depreciation table after a change in the use. If a taxpayer chooses to use an optional depreciation table for the MACRS property after a change in the use, the depreciation allowances for the MACRS property for any 12-month taxable year beginning with the year of change are determined as follows:

(A) Change in the use results in a shorter recovery period and/or a more accelerated depreciation method. If a change in the use results in a shorter recovery period and/or a more accelerated depreciation method (as described in paragraph (d)(3)(i) of this section), the depreciation allowances for the MACRS property for any 12-month taxable year beginning with the year of change are determined by multiplying the adjusted depreciable basis of the MACRS property as of the first day of the year of change by the annual depreciation rate for each recovery year (expressed as a decimal equivalent) specified in the appropriate optional depreciation table. The appropriate optional depreciation table for the MACRS property is based on the depreciation system, depreciation method, recovery period, and convention applicable to the MACRS property in the year of change as determined under paragraph (d)(3)(i) of this section. The depreciation allowance for the year of change for the MACRS property is determined by taking into account the applicable convention (which is already factored into the optional depreciation tables). If the year of change or any subsequent taxable year is less than 12 months, the depreciation allowance determined under this paragraph (d)(5)(ii)(A) must be adjusted for a short taxable year (for further guidance, for example, see Rev. Proc. 89-15 (1989-1 C.B. 816) (see § 601.601(d)(2)(ii)(b) of this chapter)).

(B) Change in the use results in a longer recovery period and/or a slower depreciation method—(1) Determination of the appropriate optional depreciation table. If a change in the use results in a longer recovery period and/or a slower depreciation method (as described in paragraph (d)(4)(i) of this section), the depreciation allowances for the MACRS property for any 12-month taxable year beginning with the year of change are determined by choosing the optional depreciation table that corresponds to the depreciation system, depreciation method, recovery period, and convention that would have applied to the MACRS property in the placed-in-service year had that property been originally placed in service by the taxpayer with the longer recovery period and/or the slower depreciation method. If there is a change in the use of MACRS property, the applicable convention that applies to the MACRS property is the same as the convention that applied before the change in the use of the MACRS property. If the year of change or any subsequent taxable year is less than 12 months, the depreciation allowance determined under this paragraph (d)(5)(ii)(B) must be adjusted for a short taxable year (for further guidance, for example, see Rev. Proc. 89-15 (1989-1 C.B. 816) (see § 601.601(d)(2)(ii)(b) of this chapter)).

(2) Computation of the depreciation allowance. The depreciation allowances for the MACRS property for any 12-month taxable year beginning with the year of change are computed by first determining the appropriate recovery year in the table identified under paragraph (d)(5)(ii)(B)(1) of this section. The appropriate recovery year for the year of change is the year that corresponds to the year of change. For example, if the recovery year for the year of change would have been Year 4 in the table that applied before the change in the use of the MACRS property, then the recovery year for the year of change is Year 4 in the table identified under paragraph (d)(5)(ii)(B)(1) of this section. Next, the annual depreciation rate (expressed as a decimal equivalent) for each recovery year is multiplied by a transaction coefficient. The transaction coefficient is the formula (1 / (1−x)) where x equals the sum of the annual depreciation rates from the table identified under paragraph (d)(5)(ii)(B)(1) of this section (expressed as a decimal equivalent) for the taxable years beginning with the placed-in-service year of the MACRS property through the taxable year immediately prior to the year of change. The product of the annual depreciation rate and the transaction coefficient is multiplied by the adjusted depreciable basis of the MACRS property as of the beginning of the year of change.

(6) Examples. The application of this paragraph (d) is illustrated by the following examples:

(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.

(e) Change in the use of MACRS property during the placed-in-service year—(1) In general. Except as provided in paragraph (e)(2) of this section, if a change in the use of MACRS property occurs during the placed-in-service year and the property continues to be MACRS property owned by the same taxpayer, the depreciation allowance for that property for the placed-in-service year is determined by its primary use during that year. The primary use of MACRS property may be determined in any reasonable manner that is consistently applied to the taxpayer's MACRS property. For purposes of this paragraph (e), the determination of whether the mid-quarter convention applies to any MACRS property placed in service during the year of change is made in accordance with § 1.168(d)-1.

(2) Alternative depreciation system property—(i) Property used within and outside the United States. The depreciation allowance for the placed-in-service year for MACRS property that is used within and outside the United States is determined by its predominant use during that year. The determination of whether MACRS property is used predominantly outside the United States during the placed-in-service year shall be made in accordance with the test in § 1.48-1(g)(1)(i) for determining predominant use.

(ii) Tax-exempt bond financed property. The depreciation allowance for the placed-in-service year for MACRS property that changes to tax-exempt bond financed property, as described in section 168(g)(1)(C) and (g)(5), during that taxable year is determined under the alternative depreciation system. For purposes of this paragraph (e), MACRS property changes to tax-exempt bond financed property when a tax-exempt bond is first issued after the MACRS property is placed in service. MACRS property continues to be tax-exempt bond financed property in the hands of the taxpayer even if the tax-exempt bond (including any refunding issue) is not outstanding at, or is redeemed by, the end of the placed-in-service year.

(iii) Other mandatory alternative depreciation system property. The depreciation allowance for the placed-in-service year for MACRS property that changes to, or changes from, property described in section 168(g)(1)(B) (tax-exempt use property) or (D) (imported property covered by an Executive order) during that taxable year is determined under—

(A) The alternative depreciation system if the MACRS property is described in section 168(g)(1)(B) or (D) at the end of the placed-in-service year; or

(B) The general depreciation system if the MACRS property is not described in section 168(g)(1)(B) or (D) at the end of the placed-in-service year, unless other provisions of the Internal Revenue Code or regulations under the Internal Revenue Code require the depreciation allowance for that MACRS property to be determined under the alternative depreciation system (for example, section 168(g)(7)).

(3) Examples. The application of this paragraph (e) is illustrated by the following examples:

(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).

(f) No change in accounting method. A change in computing the depreciation allowance in the year of change for property subject to this section is not a change in method of accounting under section 446(e). See § 1.446-1(e)(2)(ii)(d)(3)(ii).

(g) Effective dates—(1) In general. Except as provided in paragraph (g)(2) of this section, this section applies to any change in the use of MACRS property in a taxable year ending on or after June 17, 2004. For any change in the use of MACRS property after December 31, 1986, in a taxable year ending before June 17, 2004, the Internal Revenue Service will allow any reasonable method of depreciating the property under section 168 in the year of change and the subsequent taxable years that is consistently applied to any property for which the use changes in the hands of the same taxpayer or the taxpayer may choose, on a property-by-property basis, to apply the provisions of this section.

(2) Qualified property under section 168(k) acquired and placed in service after September 27, 2017—(i) In general. The language “or § 1.168(k)-2(g)(6)(iii), as applicable” in paragraph (b)(1) of this section, the language “or § 1.168(k)-2(g)(6)(ii), as applicable” in paragraph (c) of this section, and the language “or § 1.168(k)-2(g)(6)(iv), as applicable” in paragraphs (d)(3)(i)(C) and (d)(4)(i) of this section applies to any change in use of MACRS property, which is qualified property under section 168(k)(2), by a taxpayer during or after the taxpayer's taxable year that includes September 24, 2019.

(ii) Early application. A taxpayer may choose to apply the language “or § 1.168(k)-2(g)(6)(iii), as applicable” in paragraph (b)(1) of this section, the language “or § 1.168(k)-2(g)(6)(ii), as applicable” in paragraph (c) of this section, and the language “or § 1.168(k)-2(g)(6)(iv), as applicable” in paragraphs (d)(3)(i)(C) and (d)(4)(i) of this section for any change in use of MACRS property, which is qualified property under section 168(k)(2) and acquired and placed in service after September 27, 2017, by the taxpayer during taxable years ending on or after September 28, 2017.

(iii) Early application of regulation project REG-104397-18. A taxpayer may rely on the language “or § 1.168(k)-2(f)(6)(iii), as applicable” in paragraph (b)(1) of this section, the language “or § 1.168(k)-2(f)(6)(ii), as applicable” in paragraph (c) of this section, and the language “or § 1.168(k)-2(f)(6)(iv), as applicable” in paragraphs (d)(3)(i)(C) and (d)(4)(i) of this section in regulation project REG-104397-18 (2018-41 I.R.B. 558) (see § 601.601(d)(2)(ii)(b) of this chapter) for any change in use of MACRS property, which is qualified property under section 168(k)(2) and acquired and placed in service after September 27, 2017, by the taxpayer during taxable years ending on or after September 28, 2017, and ending before the taxpayer's taxable year that includes September 24, 2019.

(3) Change in method of accounting—(i) In general. If a taxpayer adopted a method of accounting for depreciation due to a change in the use of MACRS property in a taxable year ending on or after December 30, 2003, and the method adopted is not in accordance with the method of accounting for depreciation provided in this section, a change to the method of accounting for depreciation provided in this section is a change in the method of accounting to which the provisions of sections 446(e) and 481 and the regulations under sections 446(e) and 481 apply. Also, a revocation of the election provided in paragraph (d)(3)(ii) of this section to disregard a change in the use is a change in method of accounting to which the provisions of sections 446(e) and 481 and the regulations under sections 446(e) and 481 apply. However, if a taxpayer adopted a method of accounting for depreciation due to a change in the use of MACRS property after December 31, 1986, in a taxable year ending before December 30, 2003, and the method adopted is not in accordance with the method of accounting for depreciation provided in this section, the taxpayer may treat the change to the method of accounting for depreciation provided in this section as a change in method of accounting to which the provisions of sections 446(e) and 481 and the regulations under sections 446(e) and 481 apply.

(ii) Automatic consent to change method of accounting. A taxpayer changing its method of accounting in accordance with this paragraph (g)(2) must follow the applicable administrative procedures issued under § 1.446-1(e)(3)(ii) for obtaining the Commissioner's automatic consent to a change in method of accounting (for further guidance, for example, see Rev. Proc. 2002-9 (2002-1 C.B. 327), (see § 601.601(d)(2)(ii)(b) of this chapter)). Any change in method of accounting made under this paragraph (g)(2) must be made using an adjustment under section 481(a). For purposes of Form 3115, Application for Change in Accounting Method, the designated number for the automatic accounting method change authorized by this paragraph (g)(2) is “88.” If Form 3115 is revised or renumbered, any reference in this section to that form is treated as a reference to the revised or renumbered form.
