Sec. 1.48-12 Qualified rehabilitated building; expenditures incurred after December 31, 1981.

(i) In general. Except as otherwise provided in this paragraph (a)(2)(i), this section applies to expenditures incurred after December 31, 1981, in connection with the rehabilitation of a qualified rehabilitated building. (See paragraph (c)(3)(i) of this section for rules concerning the determination of when an expenditure is incurred.) If, however, physical work on the rehabilitation began before January 1, 1982, and the building does not meet the requirements of paragraph (b) of this section, the rules in section 1.48-11 shall apply to the expenditures incurred after December 31, 1981, in connection with such rehabilitation. (See paragraph (b)(6)(i) of this section for rules determining when physical work on a rehabilitation begins.) The next to last sentence of paragraph (c)(8)(i) of this section applies to qualified rehabilitation expenditures that are qualified property under section 168(k)(2) or qualified New York Liberty Zone property under section 1400L(b) acquired by a taxpayer after September 10, 2001, and to qualified rehabilitation expenditures that are 50 percent bonus depreciation property under section 168(k)(4) acquired by a taxpayer after May 5, 2003. The last sentence of paragraph (c)(8)(i) of this section applies to qualified rehabilitation expenditures that are qualified property under section 168(k)(2) and placed in service by a taxpayer during or after the taxpayer’s taxable year that includes September 24, 2019. However, a taxpayer may choose to apply the last sentence in paragraph (c)(8)(i) of this section for qualified rehabilitation expenditures that are 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. A taxpayer may rely on the last sentence in paragraph (c)(8)(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 qualified rehabilitation expenditures that are 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.

(ii) Transition rules concerning ACRS lives.

(iii) Transition rule concerning external wall definition. Notwithstanding the definition of external wall contained in paragraph (b)(3)(ii) of this section, in any case in which the written plans and specifications for a rehabilitation were substantially completed on or before June 28, 1985, and the building being rehabilitated would fail to meet the requirement of paragraph (b)(1)(iii) of this section if the definition of external wall in paragraph (b)(3)(ii) of this section were used, the term "external wall" shall be defined as a wall, including its supporting elements, with one face exposed to the weather or earth, and a common wall shall not be treated as an external wall. See paragraph (b)(2)(v) of this section for the definition of written plans and specifications.

(iv) Transition rules concerning amendments made by the Tax Reform Act of 1986.

(i) That has been substantially rehabilitated (within the meaning of paragraph (b)(2) of this section) for the taxable year,

(ii) That was placed in service (within the meaning of section 1.46-3(d)) as a building by any person before the beginning of the rehabilitation, and

(iii) That meets the applicable existing external wall retention test or the existing external wall and internal structural framework retention test in accordance with paragraph (b)(3) of this section.

(i) Substantial rehabilitation test. A building shall be treated as having been substantially rehabilitated for a taxable year only if the qualified rehabilitation expenditures (as defined in paragraph (c) of this section) incurred during any 24-month period selected by the taxpayer ending with or within the taxable year exceed the greater of--

(ii) Date to determine adjusted basis of the building.

(iii) Adjusted basis of the building.

(iv) Rehabilitation. Rehabilitation includes renovation, restoration, or reconstruction of a building, but does not include an enlargement (within the meaning of paragraph (c)(10) of this section) of new construction. The determination of whether expenditures are attributable to the rehabilitation of an existing building or to new construction shall be based upon all the facts and circumstances.

(v) Special rule for phased rehabilitation. In the case of any rehabilitation that may reasonably be expected to be completed in phases set forth in written architectural plans and specifications completed before the physical work on the rehabilitation begins, paragraphs (b)(2) (i), (ii), and (vii) of this section shall be applied by substituting "60-month period" for "24-month period." A rehabilitation may reasonably be expected to be completed in phases if it consists of two or more distinct stages of development. The determination of whether a rehabilitation consists of distinct stages and therefore may reasonably be expected to be completed in phases shall be made on the basis of all the relevant facts and circumstances in existence before physical work on the rehabilitation begins. For purposes of this paragraph and paragraph (a)(2)(iii) of this section, written plans that describe generally all phases of the rehabilitation process shall be treated as written architectural plans and specifications. Such written plans are not required to contain detailed working drawings or detailed specifications of the materials to be used. In addition, the taxpayer may include a description of work to be done by lessees in the written plans. For example, where the owner of a vacant four story building plans to rehabilitate two floors of the building and plans to require, as a condition of any lease, that tenants of the other two floors must rehabilitate those floors, the requirements of this paragraph (b)(2)(v) shall be met if the owner provides written plans for the rehabilitation work to be done by the owner and a description of the rehabilitation work that the tenants will be required to complete. The work required of the tenants may be described in the written plans in terms of minimum specifications (e.g., as to lighting, wiring, materials, appearance) that must be met by such tenants. See paragraph (b)(6)(i) of this section for the definition of physical work on a rehabilitation.

(vi) Treatment of expenses incurred by persons who have an interest in the building. For purposes of the substantial rehabilitation test in paragraph (b)(2)(i) of this section, the taxpayer may take into account qualified rehabilitation expenditures incurred during the same rehabilitation process by any other person who has an interest in the building. Thus, for example, to determine whether a building has been substantially rehabilitated, a lessee may include the expenditures of the lessor and of other lessees; a condominium owner may include the expenditures incurred by other condominium owners; and an owner may include the expenditures of the lessees.

(vii) Special rules when qualified rehabilitation expenditures are treated as incurred by the taxpayer. In the case where qualified rehabilitation expenditures are treated as having been incurred by a taxpayer under paragraph (c)(3)(ii) of this section, the transferee shall be treated as having incurred the expenditures incurred by the transferor on the date that the transferor incurred the expenditures with the meaning of paragraph (c)(3)(i) of this section. For purposes of the substantial rehabilitation test in paragraph (b)(2)(i) of this section, the transferee's adjusted basis in the building shall be determined as of the beginning of the first day of a 24-month period, or the first day of the transferee's holding period, whichever is later, as provided in paragraph (b)(2)(ii) of this section. The transferee's basis as of the first day of the transferee's holding period for purposes of the substantial rehabilitation test in paragraph (b)(2)(i) of this section, however, shall be considered to be equal to the transferee's basis in the building on such date less--

(viii) Statement of adjusted basis, measuring period, and qualified rehabilitation expenditures. In the case of any tax return filed after August 27, 1985, on which an investment tax credit for property, described in section 48(a)(1)(E) is claimed, the taxpayer shall indicate by way of a marginal notation on, or a supplemental statement attached to, Form 3468--

Furthermore, for returns filed after August 27, 1985, if the adjusted basis of the building for purposes of the substantial rehabilitation test is determined in whole or in part by reference to the adjusted basis of a person, or persons, other than the taxpayer (e.g., a rehabilitation by a lessee), the taxpayer must attach to the Form 3468 filed with the tax return on which the credit is claimed a statement addressed to the District Director, signed by such third party, that states the first day of the third party's holding period and the amount of the adjusted basis of such third party in the building at the beginning of the measuring period or the first day of the holding period, whichever is later. If the taxpayer is unable to obtain the required information, that fact should be indicated and the taxpayer should state the manner in which the adjusted basis was determined and, if different, the fair market value of the building on the relevant date.

(ix) Partnerships and S corporations. If a building is owned by a partnership (i.e., the building is partnership property) or an S corporation, the substantial rehabilitation test shall be determined at the entity level. Thus, the entity shall compare the amount of qualified rehabilitation expenditures incurred during the measuring period against its basis in the building at the beginning of its holding period or the beginning of its measuring period, whichever is later. (See section 1223(2) for rules concerning the determination of a partnership's holding period in the case of a contribution of property to the partnership meeting the requirements of section 721.) The adjusted basis of the building to a partnership shall be determined by taking into account any adjustments to the basis of the building made under section 743 and section 734. Any adjustments to the building's basis that are made under section 743 or section 734 after the beginning of the partnership's holding period, but before the end of the measuring period, shall be deemed for purposes of the substantial rehabilitation test to have been made on the first day of the partnership's holding period. However, in such case, the partnership's basis in the building shall be reduced by the amount of qualified rehabilitation expenditures incurred by the partnership. In the case of any tax return filed after January 9, 1989 on which a credit is claimed by a partner or a shareholder of an S corporation for rehabilitation expenditures incurred by a partnership or an S corporation, the partner or shareholder shall indicate on the Form 3468 on which the credit is claimed the name, address, and identification number of the partnership or S corporation that incurred the rehabilitation expenditures, and the partnership or S corporation shall, by way of a marginal notation on or a supplemental statement attached to the entity's return, provide the information required by paragraph (b)(2)(viii) of this section.

(x) Examples. The following examples illustrate the application of the substantial rehabilitation test in this paragraph (b)(2):

Example 1. Assume that A, a calendar year taxpayer, purchases a building for $140,000 on January 1, 1982, incurs qualified rehabilitation expenditures in the amount of $48,000 (at the rate of $4,000 per month) in 1982, $100,000 in 1983, and $20,000 (at the rate of $2,000 per month) in the first ten months of 1984, and places the rehabilitated building in service on October 31, 1984. Assume that A did not have written architectural plans and specifications describing a phased rehabilitation within the meaning of paragraph (b)(2)(v) of this section in existence prior to the beginning of physical work on the rehabilitation. For purposes of the substantial rehabilitation test in paragraph (b)(2) of this section, A may select any 24-consecutive-month measuring period that ends in 1984, the taxable year in which the rehabilitated building was placed in service. Assume that on A's 1984 return, A selects a measuring period beginning on February 1, 1982, and ending on January 31, 1984, and specifies that A's basis in the building (within the meaning of section 1011(a)) was $144,000 on February 1, 1982 ($140,000+$4,000). (The $4,000 of rehabilitation expenditures incurred during January 1982 are included in A's basis under section 1011 even though such property has not been placed in service.) The amount of qualified rehabilitation expenditures incurred during the measuring period was $146,000 ($44,000 from February 1 to December 31, 1982, plus $100,000 in 1983, plus $2,000 in January 1984). The building shall be treated as "substantially rehabilitated" within the meaning of this paragraph (b)(2) for A's 1984 taxable year because the $146,000 of expenditures incurred by A during the measuring period exceeded A's adjusted basis of $144,000 at the beginning of the period. If the other requirements of section 48(g)(1) and this paragraph are met, the building is treated as a qualified rehabilitated building, and A can treat as qualified rehabilitation expenditures the amount of $168,000 (i.e., $146,000 of expenditures incurred during the measuring period, $4,000 of expenditures incurred prior to the beginning of the measuring period as part of the rehabilitation process, and $18,000 of expenditures incurred after the measuring period during the taxable year within which the measuring period ends (See paragraph (c)(6) of this section.)). The result would generally be the same if the property attributable to the rehabilitation expenditures was placed in service as the expenditures were incurred, but A would have $148,000 of qualified rehabilitation expenditures for 1983 and $20,000 of qualified rehabilitation expenditures for 1984. (See paragraph (f)(2) of this section).

Example 2. Assume the same facts as in example 1, except that additional rehabilitation expenditures are incurred after the portion of the basis of the building attributable to qualified rehabilitation expenditures was placed in service on October 31, 1984. Such expenditures are incurred through the end of 1984 and in 1985 when the portion of the basis attributable to the additional expenditures is placed in service. The fact that the building qualified as a substantially rehabilitated building for A's 1984 taxable year has no effect on whether the building is a qualified rehabilitated building for property placed in service in A's 1985 taxable year. In order to determine whether the building is a qualified rehabilitated building for A's 1985 taxable year, A must select a measuring period that ends in 1985 and compare the expenditures incurred within that period with the adjusted basis as of the beginning of the period. Solely for the purpose of determining whether the building was substantially rehabilitated for A's 1985 taxable year, expenditures incurred during 1983 and 1984, even though considered in determining whether the building was substantially rehabilitated in 1984, may also be used to determine whether the building was substantially rehabilitated for A's 1985 taxable year, provided the expenditures were incurred during any 24-month measuring period selected by A that ends in 1985.

Example 3. (i) Assume the B purchases a building for $100,000 on January 1, 1982, and leases the building to C who rehabilitates the building. Assume that C, a calendar year taxpayer, places the property with respect to which rehabilitation expenditures were made in service in 1982 and selects December 31, 1982, as the end of the measuring period for purposes of the substantial rehabilitation test. The beginning of the measuring period is January 2, 1982, the beginning of B's holding period under section 1250(e), and the adjusted basis of the building is $100,000. Accordingly, if C incurred more than $100,000 of qualified rehabilitation expenditures during 1982, the building would be substantially rehabilitated within the meaning of paragraph (b)(2)(i) of this section.

(ii) Assume the facts of example 3(i), except that after C begins physical work on the rehabilitation, but before C incurs $100,000 of expenditures, D acquires the building, subject to C's lease, from B for $200,000. D's holding period under section 1250(e) begins on the day after D acquired the building, and C's adjusted basis for purposes of the substantial rehabilitation test is $200,000, less the the amount of expenditures incurred by C before the transfer. (See paragraph (b)(2) (ii) and (vii) of this section.) Accordingly, if C incurred more than $200,000 (less the amount of expenditures incurred prior to the transfer) of qualified rehabilitation expenditures during 1982, the building would be substantially rehabilitated within the meaning of paragraph (b)(2) of this section. Under paragraph (b)(2)(ii)(B) of this section, however, C's adjusted basis for purposes of the substantial rehabilitation test would be $100,000 if C had substantially rehabilitated the building (i.e., incurred more than $100,000 in rehabilitation expenditures) prior to B's sale to D.

Example 4. E owns a building with a basis of $10,000 and E incurs $5,000 of rehabilitation expenditures. Before completing the rehabilitation project, E sells the building to F for $30,000. Assume that F is treated under paragraph (c)(3)(ii) of this section as having incurred the $5,000 of rehabilitation expenditures actually incurred by E. Because F's basis in the building is determined under section 1011 with reference to F's $30,000 cost of the building (which includes the property attributable to E's rehabilitation expenditures), F's basis for purposes of the substantial rehabilitation test is $25,000 ($30,000 cost basis less $5,000 rehabilitation expenditures treated as if incurred by F). (See paragraph (b)(2)(vii) of this section.) F would thus be required to incur more than $20,000 of rehabilitation expenditures (in addition to the $5,000 incurred by E and treated as having been incurred by F) during a measuring period selected by F to satisfy the substantial rehabilitation test.

Example 5. G owns Building I with a basis of $10,000 and a fair market value of $20,000. H owns Building II with a basis of $5,000 and a fair market value of $20,000, with respect to which H has incurred $1,000 of rehabilitation expenditures. G and H exchange their buildings in a transaction that qualifies for nonrecognition treatment under section 1031. Assume that G is treated under paragraph (c)(3)(ii) of this section as having incurred $1,000 of rehabilitation expenditures. G's basis in Building II, computed under section 1031(d), is $10,000. G's basis in Building II is not determined with reference to (A) the cost of Building II, (B) H's basis in Building II (including the cost of the rehabilitation expenditures) or (C) any other amount that includes the cost of expenditures, but is instead determined with reference to G's basis in other property (Building I). Therefore, G's basis in Building II for purposes of the substantial rehabilitation test is not reduced by the $1,000 of rehabilitation expenditures treated as if incurred by G. (See paragraph (b)(2)(vii) of this section.) Accordingly, G's basis in Building II for purposes of the substantial rehabilitation test is $10,000, and G must incur additional rehabilitation expenditures in excess of $9,000 within a measuring period selected by G to satisfy the test.

(i) In general.

(ii) Definition of external wall. For purposes of this paragraph (b), a wall includes both the supporting elements of the wall and the nonsupporting elements, (e.g., a curtain, windows or doors) of the wall. Except as otherwise provided in this paragraph (b)(3), the term "`external wall" includes any wall that has one face exposed to the weather, earth, or an abutting wall of an adjacent building. The term "external wall" also includes a shared wall (i.e., a single wall shared with an adjacent building), generally referred to as a "party wall," provided that the shared wall has no windows or doors in any portion of the wall that does not have one face exposed to the weather, earth, or an abutting wall. In general, the term "external wall" includes only those external walls that form part of the outline or perimeter of the building or that surround an uncovered courtyard. Therefore, the walls of an uncovered internal shaft, designed solely to bring light or air into the center of a building, which are completely surrounded by external walls of the building and which enclose space not designated for occupancy or other use by people (other than for maintenance or emergency), are not considered external walls. Thus, for example, a wall of a light well in the center of a building is not an external wall. However, walls surrounding an outdoor space which is usable by people, such as a courtyard, are external walls.

(iii) Definition of internal structural framework. For purposes of this section, the term "internal structural framework" includes all load-bearing internal walls and any other internal structural supports, including the columns, girders, beams, trusses, spandrels, and all other members that are essential to the stability of the building.

(iv) Retained in place. An existing external wall is retained in place if the supporting elements of the wall are retained in place. An existing external wall is not retained in place if the supporting elements of the wall are replaced by new supporting elements. An external wall is retained in place, however, if the supporting elements are reinforced in the rehabilitation, provided that such supporting elements of the external wall are retained in place. An external wall also is retained in place if it is covered (e.g., with new siding). Moreover, an external wall is retained in place if the existing curtain is replaced with a new curtain, provided that the structural framework that provides for the support of the existing curtain is retained in place. An external wall is retained in place notwithstanding that the existing doors and windows in the wall are modified, eliminated, or replaced. An external wall is retained in place if the wall is disassembled and reassembled, provided the same supporting elements are used when the wall is reassembled and the configuration of the external walls of the building after the rehabilitation is the same as it was before the rehabilitation process commenced. Thus, for example, a brick wall is considered retained in place even though the original bricks are removed (for cleaning, etc.) and replaced to form the wall. The principles of this paragraph (b)(3)(iv) shall also apply to determine whether internal structural framework of the building is retained in place.

(v) Effect of additions. If an existing external wall is converted into an internal wall (i.e., a wall that is not an external wall), the wall is not retained in place as an external wall for purposes of this section.

(vi) Examples. The provisions of this paragraph (b)(3) may be illustrated by the following examples:

Example 1. Taxpayer A rehabilitated a building all of the walls of which consisted of wood siding attached to gypsum board sheets (which covered the supporting elements of the wall, i.e., studs). A covered the existing wood siding with aluminum siding as part of a rehabilitation that otherwise qualified under this subparagraph. The addition of the aluminum siding does not affect the status of the existing external walls as external walls and they would be considered to have been retained in place.

Example 2. Taxpayer B rehabilitated a building, the external walls of which had a masonry curtain. The masonry on the wall face was replaced with a glass curtain. The steel beam and girders supporting the existing masonry curtain were retained in place. The walls of the building are considered to be retained in place as external walls, notwithstanding the replacement of the curtain.

Example 3. Taxpayer C rehabilitated a building that has two external walls measuring 75' x 20' and two other external walls measuring 100' x 20'. C demolished one of the larger walls, including its supporting elements and constructed a new wall. Because one of the larger walls represents more than 25 percent of the area of the building's external walls, C has not satisfied the requirements that 75 percent of the existing external walls must be retained in place as either internal or external walls. If however, C had not demolished the wall, but had converted it into an internal wall (e.g., by building a new external wall), the building would satisfy the external wall requirements.

Example 4. The facts are the same as in example 3, except that C does not tear down any walls, but builds an addition that results in one of the smaller walls becoming an internal wall. In addition, C enlarged 8 of the existing windows on one of the larger walls, increasing them from a size of 3' x 4' to 6' x 8'. Since the smaller wall accounts for less than 25 percent of the total wall area, C has satisfied the requirement that 75 percent of the existing external walls must be retained in place as external walls in the rehabilitation process. The enlargement of the existing windows on the larger wall does not affect its status as an external wall.

Example 5. Taxpayer D rehabilitated a building that was in the center of a row of three buildings. The building being rehabilitated by D shares its side walls with the buildings on either side. The shared walls measure 100'x 20' and the rear and front walls measure 75' x 20'. As part of a rehabilitation, D tears down and replaces the front wall. Because the shared walls as well as the front and back walls are considered external walls and the front wall accounts for less than 25 percent of the total external wall area (including the shared walls), D has satisfied the requirement that 75 percent of the existing external walls must be retained in place as external walls in the rehabilitation process.

(i) In general.

(ii) Additions. A building that was first placed in service before 1936 in the case described in paragraph (b)(4)(i)(A) of this section, or at least 30 years before physical work on the rehabilitation began in the case described in paragraph (b)(4)(i)(B) of this section, will not be disqualified because additions to such building have been added since 1936 in the case described in paragraph (b)(4)(i)(A) of this section, or are less than 30 years old in the case described in paragraph (b)(4)(i)(B) of this section. Such additions, however, shall not be treated as part of the qualified rehabilitated building. The term "addition" means any construction that resulted in any portion of an external wall becoming an internal wall, that resulted in an increase in the height of the building, or that increased the volume of the building.

(iii) Vacant periods. The determinations required by paragraph (b)(4)(i) of this section include periods during which a building was vacant or devoted to a personal use and is computed without regard to the number of owners or the identify of owners during the period.

(i) Physical work on a rehabilitation. For purposes of this section, "physical work on a rehabilitation" begins when actual construction, or destruction in preparation for construction, begins. The term "physical work on a rehabilitation," however, does not include preliminary activities such as planning, designing, securing financing, exploring, researching, developing plans and specifications, or stabilizing a building to prevent deterioration (e.g., placing boards over broken windows).

(ii) Special rule for adjoining buildings that are combined. For purposes of this paragraph (b), if as part of a rehabilitation process two or more adjoining buildings are combined and placed in service as a single building after the rehabilitation process, then, at the election of the taxpayer, all of the requirements for a qualified rehabilitated building in section 48(g)(1) and this section may be applied to the constituent adjoining buildings in the aggregate. For example, if such requirements are applied in the aggregate, any shared walls or abutting walls between the constituent buildings that would otherwise be treated as external walls (within the meaning of paragraph (b)(3) of this section) would not be treated as external walls of the building, and the substantial rehabilitation test in paragraph (b)(2) of this section would be applied to the aggregate expenditures with respect to all of the constituent buildings and to the aggregate adjusted basis of all of the constituent buildings. A taxpayer shall elect the special rule of this paragraph (b)(6)(ii) for adjoining buildings by indicating by way of a marginal notation on, or a supplemental statement attached to, the Form 3468 on which a credit is first claimed for qualified rehabilitation expenditures with respect to such buildings that such buildings are a single qualified rehabilitated building because of the application of the special rule in this paragraph (b)(6)(ii).

(i) Properly chargeable to capital account (as described in paragraph (c)(2) of this section),

(ii) Incurred by the taxpayer after December 31, 1981 (as described in paragraph (c)(3) of this section),

(iii) For property for which depreciation is allowable under section 168 and which is real property described in paragraph (c)(4) of this section, and

(iv) Made in connection with the rehabilitation of a qualified rehabilitated building (as described in paragraph (c)(5) of this section).

(i) In general. Qualified rehabilitation expenditures are incurred by the taxpayer for purposes of this section on the date such expenditures would be considered incurred under an accrual method of accounting, regardless of the method of accounting used by the taxpayer with respect to other items of income and expense. If qualified rehabilitation expenditures are treated as having been incurred by a taxpayer under paragraph (c)(3)(ii) of this section, the taxpayer shall be treated as having incurred the expenditures on the date such expenditures were incurred by the transferor.

(ii) Qualified rehabilitation expenditures treated as incurred by the taxpayer--

(iii) Examples. The provisions of this paragraph (c) may be illustrated by the following examples:

Example 1. In 1981, A, a taxpayer using the cash receipts and disbursements method of accounting, commenced the rehabilitation of a 30-year old building. In June 1981, A signed a contract with a plumbing contractor for replacement of the plumbing in the building. A agreed to pay the contractor as soon as the work was completed. The work was completed in December 1981, but A did not pay the amount due until January 15, 1982. The expenditures for the plumbing are not qualified rehabilitation expenditures (within the meaning of this paragraph (c)) because they were not incurred under an accrual method of accounting after December 31, 1981.

Example 2. B incurred qualified rehabilitation expenditures of $300,000 with respect to an existing building between January 1, 1982, and May 15, 1982, and then sold the building to C on June 1, 1982. The portion of the building to which the expenditures were allocable was not used by B or any other person during the period from January 1, 1982, to June 1, 1982, and neither B nor any other person claimed the credit. Consequently, C will be treated as having incurred the expenditures on the dates that B incurred the expenditures.

Example 3. D, a taxpayer using the cash receipts and disbursements method of accounting, begins the rehabilitation of a building on January 11, 1982. Prior to May 1, 1982, D makes rehabilitation expenditures of $16,000. On May 3, 1982, D sells the building, the land, and the property attributable to the rehabilitation expenditures to E for $35,000. The purchase price is properly allocable as follows:

The property attributable to the rehabilitation expenditures is placed in service by E on September 5, 1982. E may treat a portion of the $35,000 purchase price as rehabilitation expenditures paid or incurred by him. Since the rehabilitation expenditures paid by D ($16,000) are less than the portion of the purchase price properly allocable to property attributable to these expenditures ($19,000), E may treat only $16,000 as rehabilitation expenditures paid or incurred by him. The excess of the purchase price allocable to rehabilitation expenditures ($19,000) over the rehabilitation expenditures paid by D ($16,000), or $3,000, is treated as the cost of acquiring an interest in the building and is not a qualified rehabilitation expenditure treated as incurred by E.

Example 4. The facts are the same as in example 3, except that the purchase price properly allocable to the property attributable to rehabilitation expenditures is $15,000. Under these circumstances, E may treat only $15,000 of D's $16,000 expenditures as rehabilitation expenditures paid by D. The excess of the rehabilitation expenditures paid by D ($16,000) over the purchase price allocable to rehabilitation expenditures ($15,000), or $1,000, is treated as the cost of acquiring an interest in the building and is not a qualified rehabilitation expenditure treated as incurred by E.

(i) Property placed in service after December 31, 1986. Except as otherwise provided in paragraph (c)(4)(ii) of this section (relating to certain property that qualifies under a transition rule), in the case of property placed in service after December 31, 1986, an expenditure is incurred for depreciable real property for purposes of paragraph (c)(1)(iii) of this section, only if it is added to the depreciable basis of depreciable property which is--

For purposes of this paragraph (c)(4)(i), the terms "nonresidential real property", "residential rental property", and "class life" have the respective meanings given to such terms by section 168 and the regulations thereunder.

(ii) Property placed in service before January 1, 1987, and property that qualifies under a transition rule. In the case of property placed in service before January 1, 1987, and property placed in service after December 31, 1986, that qualifies for the transition rules in paragraph (a)(2)(iv) (B) or (C) of this section, an expenditure attributable to such property shall be a qualified rehabilitation expenditure only if such expenditure is incurred for property that is real property (or additions or improvements to real property) with a recovery period (within the meaning of section 168 as in effect prior to its amendment by the Tax Reform Act of 1986) of 19 years (15 years for low-income housing) and if the other requirements of this paragraph (c) are met. For purposes of this section, an expenditure is incurred for recovery property having a recovery period of 19 years only if the amount of the expenditure is added to the basis of property which is 19-year real property or 15-year real property in the case of low-income housing. For purposes of this section, the term "low-income housing" has the meaning given such term by section 168(c)(2)(F) (as in effect prior to the amendments made by the Tax Reform Act of 1986).

(i) Before the beginning of a measuring period during which the building was substantially rehabilitated that ends with or within the taxable year, provided that the expenditures were incurred in connection with the rehabilitation process that resulted in the substantial rehabilitation of the building;

(ii) Within a measuring period during which the building was substantially rehabilitated that ends with or within the taxable year, and

(iii) After the end of a measuring period during which the building was substantially rehabilitated but prior to the end of the taxable year with or within which the measuring period ends.

(i) Except as otherwise provided in paragraph (c)(8) of this section, any expenditure with respect to which the taxpayer does not use the straight line method over a recovery period determined under section 168(c) and (g).

(ii) The cost of acquiring a building, any interest in a building (including a leasehold interest), or land, except as provided in paragraph (c)(3)(ii) of this section.

(iii) Any expenditure attributable to an enlargement of a building (within the meaning of paragraph (c)(10) of this section).

(iv) Any expenditure attributable to the rehabilitation of a certified historic structure or a building located in a registered historic district, unless the rehabilitation is a certified rehabilitation. (See paragraph (d) of this section which contains definitions and special rules applicable to rehabilitations of certified historic structures and buildings located in registered historic districts.)

(v) Any expenditure of a lessee of a building or a portion of a building, if, on the date the rehabilitation is completed with respect to property placed in service by such lessee, the remaining term of the lease (determined without regard to any renewal period) is less than the recovery period determined under section 168(c) (or 19 years in the case of property placed in service before January 1, 1987, and property placed in service that qualifies under the transition rules in paragraph (a)(2)(iv)(B) or (C) of this section).

(vi) Any expenditure allocable to that portion of a building which is (or may reasonably be expected to be) tax-exempt use property (within the meaning of section 168 and the regulations thereunder), except that the exclusion in this paragraph (c)(7)(vi) shall not apply for purposes of determining whether the building is a substantially rehabilitated building under paragraph (b)(2) of this section.

(i) Property placed in service after December 31, 1986. The requirement in section 48(g)(2)(B)(i) and paragraph (c)(7)(i) of this section to use straight line cost recovery does not apply to any expenditure to the extent that the alternative depreciation system of section 168(g) applies to such expenditure by reason of section 168(g)(1)(B) or (C). In addition, the requirement in section 48(g)(2)(B)(i) and paragraph (c)(7)(i) of this section applies only to the depreciation of the portion of the basis of a qualified rehabilitated building that is attributable to qualified rehabilitation expenditures. However, see Section 1.168(k)-1(f)(10) if the qualified rehabilitation expenditures are qualified property or 50-percent bonus depreciation property under section 168(k) and see § 1.1400L(b)-1(f)(9) if the qualified rehabilitation expenditures are qualified New York Liberty Zone property under section 1400L(b). Further, see §1.168(k)-2(g)(9) if the qualified rehabilitation expenditures are qualified property under section 168(k), as amended by the Tax Cuts and Jobs Act, Public Law 115-97 (131 Stat. 2054 (December 22, 2017)).

(ii) Property placed in service before January 1, 1987, and property placed in service after December 31, 1986, that qualifies for a transition rule. In the case of expenditures attributable to property placed in service before January 1, 1987, and property that qualifies for the transition rules in paragraph (a)(2)(iv) (B) or (C) of this section, the term "qualified rehabilitation expenditure" does not include an expenditure with respect to which an election was not made under section 168(b)(3) as in effect prior to its amendment by the Tax Reform Act of 1986, to use the straight line method of depreciation. In such case, the requirement that an election be made to use straight line cost recovery applies only to the cost recovery of the portion of the basis of a qualified rehabilitated building that is attributable to qualified rehabilitation expenditures. See section 168(f)(1), as in effect prior to its amendment by the Tax Reform Act of 1986, for rules relating to the use of different methods of cost recovery for different components of a building. In addition, such requirement shall not apply to any expenditure to the extent that section 168(f)(12) or (j), as in effect prior to the amendments made by the Tax Reform Act of 1986, applied to such expenditure.

(i) In general. A building is enlarged to the extent that the total volume of the building is increased. An increase in floor space resulting from interior remodeling is not considered an enlargement. The total volume of a building is generally equal to the product of the floor area of the base of the building and the height from the underside of the lowest floor (including the basement) to the average height of the finished roof (as it exists or existed). For this purpose, floor area is measured from the exterior faces of external walls (other than shared walls that are external walls) and from the centerline of shared walls that are external walls.

(ii) Rehabilitation that includes enlargement. If expenditures for property only partially qualify as qualified rehabilitation expenditures because some of the expenditures are attributable to the enlargement of the building, the expenditures must be apportioned between the original portion of the building and the enlargement. The expenditures must be specifically allocated between the original portion of the building and the enlargement to the extent possible. If it is not possible to make a specific allocation of the expenditures, the expenditures must be allocated to each portion on some reasonable basis. The determination of a reasonable basis for an allocation depends on factors such as the type of improvement and how the improvement relates functionally to the building. For example, in the case of expenditures for an air-conditioning system or a roof, a reasonable basis for allocating the expenditures among the two portions generally would be the volume of the building, excluding the enlargement, served by the air-conditioning system or the roof relative to the volume of the enlargement served by the improvement.

(i) Listed in the National Register of Historic Places ("National Register"); or

(ii) Located in a registered historic district and certified by the Secretary of the Interior to the Internal Revenue Service as being of historic significance to the district.

(i) Listed in the National Register, or

(ii)

(i) Such building was not a certified historic structure during the rehabilitation process; and

(ii) The Secretary of the Interior certified to the Internal Revenue Service that such building was not of historic significance to the district.

(i) In general. Except as otherwise provided in paragraph (d)(7)(ii) of this section, a taxpayer claiming the credit for rehabilitation of a certified historic structure (within the meaning of section 48(g)(3) and paragraph (d)(1) of this section) must attach to the Form 3468 filed with the tax return for the taxable year in which the credit is claimed a copy of the final certification of completed work by the Secretary of the Interior, and for returns filed after January 9, 1989, evidence that the building is a certified historic structure.

(ii) Late certification. If the final certification of completed work has not been issued by the Secretary of the Interior at the time the tax return is filed for a year in which the credit is claimed, a copy of the first page of the Historic Preservation Certification Application--Part 2--Description of Rehabilitation (NPS Form 10-168a), with an indication that it has been received by the Department of the Interior or its designate, together with proof that the building is a certified historic structure (or that such status has been requested), must be attached to the Form 3468 filed with the return. A notice from the Department of the Interior or the State Historic Preservation Officer, stating that the nomination or application has been received, or a date-stamped nomination or application shall be sufficient indication that the nomination or application has been received. The building need not be either listed in the National Register or be determined to be of historic significance to a registered historic district at the time the return is filed for the year in which the credit is claimed. (See paragraph (d)(1) of this section.) The taxpayer must submit a copy of the final certification as an attachment to Form 3468 with the first income tax return filed after the receipt by the taxpayer of the certification. If the final certification is denied by the Department of Interior, the credit will be disallowed for any taxable year in which it was claimed. If the taxpayer fails to receive final certification of completed work prior to the date that is 30 months after the date that the taxpayer filed the tax return on which the credit was claimed, the taxpayer must submit a written statement to the District Director stating such fact prior to the last day of the 30th month, and the taxpayer shall be requested to consent to an agreement under section 6501(c)(4) extending the period of assessment for any tax relating to the time for which the credit was claimed. The procedure permitted by the preceding sentence shall be used whenever the entire rehabilitation project is not fully completed by the date that is 30 months after the taxpayer filed the tax return upon which the credit was claimed (e.g. a phased rehabilitation) and the Secretary of the Interior has thus not yet certified the rehabilitation.

(iii) Effective dates. Paragraph (d)(7)(i) of this section applies to returns for taxable years beginning before January 1, 2002. The requirement in the fourth sentence of paragraph (d)(7)(ii) of this section applies only if the first income tax return filed after receipt by the taxpayer of the certification is for a taxable year beginning before January 1, 2002. For rules applicable to returns for taxable years beginning after December 31, 2001, see paragraph (d)(7)(iv) of this section.

(iv) Returns for taxable years beginning after December 31, 2001.

(i) In general. The investment credit for qualified rehabilitation expenditures is generally allowed in the taxable year in which the property attributable to the expenditure is placed in service, provided the building is a qualified rehabilitated building for the taxable year. See paragraph (b) of this section and section 46(c) and section 1.46-3(d). Under certain circumstances, however, the credit may be available prior to the date the property is placed in service. See section 46(d) and section 1.46-5 (relating to qualified progress expenditures). Solely for purposes of section 46(c), property attributable to qualified rehabilitation expenditures will not be treated as placed in service until the building with respect to which the expenditures are made meets the definition of a qualified rehabilitated building (as defined in section 48(g)(1) and paragraph (b) of this section) for the taxable year. Accordingly, in the first taxable year for which the building becomes a qualified rehabilitated building, the property described in section 48(a)(1)(E) attributable to expenditures described in paragraph (c) of this section, shall be considered to be placed in service, if such property was considered placed in service under section 46(c) and the regulations thereunder without regard to this paragraph (f)(2)(i) in that taxable year or a prior taxable year. For purposes of the preceding sentence, the requirement of section 48(g)(1)(A)(iii) and paragraph (b)(3) of this section, relating to the definition of a qualified rehabilitated building shall be deemed to be met if the taxpayer reasonably expects that no rehabilitation work undertaken during the remainder of the rehabilitation process will result in a failure to satisfy the requirements of paragraph (b)(3) of this section. If the requirements of paragraph (b)(3) of this section, are not satisfied, however, the credit shall be disallowed for the taxable year in which it was claimed. If a taxpayer fails to complete physical work on the rehabilitation prior to the date that is 30 months after the date that the taxpayer filed a tax return on which the credit is claimed, the taxpayer must submit a written statement to the District Director stating such fact prior to the last day of the 30th month, and shall be requested to consent to an agreement under section 6501(c)(4) extending the period of assessment for any tax relating to the item for which the credit was claimed.

(ii) Section 38 property described in section 48(a)(1)(E). In the case of section 38 property described in section 48(a)(1)(E), the section 38 property is not the building. Instead, the section 38 property is the portion of the basis of the building that is attributable to qualified rehabilitation expenditures. Therefore, for example, for purposes of the determination of when such section 38 property is placed in service, a determination must be made regarding when property attributable to the portion of the basis of the building attributable to qualified rehabilitation expenditures is placed in service. The issue of when the building is placed in service is thus not relevant. In fact, under this test, the building itself may never have been taken out of service during the rehabilitation process. If the building is rehabilitated over several years in stages (e.g., by floors), section 38 property attributable to qualified rehabilitation expenditures to a qualified rehabilitated building placed in service in each taxable year shall, generally, be treated as a separate item of section 38 property.

(iii) Example. The application of this paragraph (f)(2) may be illustrated by the following example:

Example. Assume that A, a calendar year taxpayer, purchases a four-story building on January 1, 1983, for $100,000, and incurs $10,000 of qualified rehabilitation expenditures in 1983 to rehabilitate floor one, $50,000 of qualified rehabilitation expenditures in 1984 to rehabilitate floor two, $70,000 of qualified rehabilitation expenditures in 1985 to rehabilitate floor three, and $60,000 of qualified rehabilitation expenditures in 1986 to rehabilitate floor four. Assume further that A places the property attributable to these expenditures in service on the last day of the year in which the respective expenditures were incurred and that the building is never taken out of service since as each floor is rehabilitated, the other three floors are occupied by tenants. Under the rule in this paragraph (f)(2), the portion of the basis of the building that is attributable to qualified rehabilitation expenditures incurred with respect to floor one and two are deemed to be placed in service in 1985, because that is the first year that the substantial rehabilitation test described in paragraph (b) of this section is met ($120,000 of expenditures incurred by A during a measuring period ending on December 31, 1985 is greater than the $110,000 basis at the beginning of the period). Assume that as of December 31, 1985, at least 75 percent of the external walls of the building have been retained during the rehabilitation process and that A has a reasonable expectation that no work during the remainder of the rehabilitation process will result in less than 75 percent of the external walls being retained. A may claim a credit for A's 1985 taxable year on $130,000 of qualified rehabilitation expenditures ($10,000 in 1983, $50,000 in 1984, and $70,000 in 1985). (See paragraph (c)(6) of this section for rules applicable to when qualified expenditures may be incurred. In addition, see section 46(d) and section 1.46-5 for rules relating to qualified progress expenditures.) The fact that the building was a qualified rehabilitated building for A's 1985 taxable year, however, has no effect on whether the building is a qualified rehabilitated building for A's 1986 taxable year. In order to determine whether A is entitled to claim a credit on A's 1986 return for the $60,000 of qualified rehabilitation expenditures incurred in 1986, A must select a measuring period ending in 1986 and must determine whether the building is a qualified rehabilitated building for that year. Solely for purposes of determining whether the building was substantially rehabilitated, expenditures incurred in 1984 and 1985, even though considered in determining whether the building was substantially rehabilitated for A's 1985 taxable year, may be used in addition to the expenditures incurred in 1986 to determine whether the building was substantially rehabilitated for A's 1986 taxable year, provided the expenditures were incurred during any measuring period selected by A that ends in 1986.
