PART 1--INCOME TAXES--Table of Contents
 
Sec. 1.48-11  Qualified rehabilitated building; expenditures incurred before January 1, 1982.

    (a) In general. Under section 48(a)(1)(E), that portion of the basis 
of a qualified rehabilitated building which is attributable to qualified 
rehabilitation expenditures qualifies as section 38 property. In 
general, property which is treated as section 38 property by reason of 
section 48(a)(1)(E) is treated as new section 38 property and therefore 
is not subject to the used property limitation. See Sec. 1.48-2(d). 
Section 48(g)(1) and paragraph (b) of this section define the term 
``qualified rehabilitated building''. Section 48(g)(2) and paragraph (c) 
of this section define the term ``qualified rehabilitation 
expenditure''. Paragraph (d) of this section provides guidance for 
coordination of these provisions with other sections of the Code.
    (b) Definition of qualified rehabilitated building--(1) In general. 
The term ``qualified rehabilitated building'' means any building and its 
structural components--
    (i) Which has been rehabilitated (within the meaning of paragraph 
(b)(3) of this section),
    (ii) Which was placed in service (within the meaning of Sec. 1.46-
3(d)) by any person at any time before the beginning of the 
rehabilitation,
    (iii) 75 percent or more of the existing external walls of which are 
retained in place as external walls (within the meaning of paragraph 
(b)(4) of this section) in the rehabilitation process, and
    (iv) Which meets the twenty-year requirement in paragraph (b)(2) of 
this section.

In addition, a major portion of a building may be treated as a separate 
building for purposes of this paragraph if the requirements of paragraph 
(b)(5) of this section are met.
    (2) Twenty-year requirement--(i) In general. A building is 
considered a qualified rehabilitated building only if a period of at 
least 20 years has elapsed between the date physical work on the 
rehabilitation of the building began, and the later of--
    (A) The date the building was first placed in service (see 
Sec. 1.46-3(d)) by any person as a building, or
    (B) The date the building was placed in service by any taxpayer in 
connection with a prior rehabilitation with respect to which a credit 
was allowed by reason of section 48(a)(1)(E).
    (ii) Vacant periods. The 20-year period includes 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 identity of owners during 
the period.
    (iii) Physical work on a rehabilitation. For purposes of this 
section, ``physical work on a rehabilitation'' begins when actual 
construction begins. The term ``physical work on a rehabilitation'' 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).
    (iv) Special rule. If a part of a building meets the twenty-years 
requirement in subdivision (i) of this subparagraph and a part (for 
example, an addition) does not, a rehabilitation of that part that meets 
the requirement may qualify for a credit only if that part constitutes a 
major portion (as defined in paragraph (b)(5) of this section) of the 
building.
    (3) Rehabilitation--(i) In general. For purposes of this paragraph, 
rehabilitation includes renovation, restoration, or reconstruction. 
However, the term ``rehabilitation'' does not include enlargement 
(within the meaning of paragraph (c)(7)(ii) of this section), new 
construction, or the completion of new construction after a building has 
been placed in service. For purposes of this paragraph (b)(3), whether 
expenditures are attributable to the rehabilitation of an existing 
building, or to new construction, is determined upon all the facts and 
circumstances.
    (ii) Substantial rehabilitation. For a building to be considered 
rehabilitated, the rehabilitation must be substantial. Whether a 
rehabilitation is substantial is determined upon the basis of all the

[[Page 371]]

facts and circumstances. In general, to be substantial, the 
rehabilitation must do one of the following:
    (A) Materially extend the useful life of the building;
    (B) Significantly upgrade its usefulness (for either the same or a 
new use); or
    (C) Preserve it in a way that significantly improves its condition 
or enhances its historic value.

A substantial rehabilitation may vary in degree from gutting and 
extensive reconstruction of a building's major structural components to 
the cure of a substantial accumulation of major disrepairs. It may also 
include renovation, alteration, or remodelling for the conversion of a 
structurally sound building to a design and condition required for a new 
use. Cosmetic improvements alone, however, do not qualify as a 
substantial rehabilitation.
    (iii) Aggregation of rehabilitation. In the case where qualified 
rehabilitation expenditures are incurred with respect to a 
rehabilitation of a building by more than one person (e.g., a lessor and 
a lessee, several lessees, or several condominium owners), the 
substantial rehabilitation requirement in this paragraph (b)(3) shall be 
applied by aggregating all the rehabilitation work done by such persons.
    (iv) Special rule by qualified rehabilitation expenditures treated 
as incurred by the taxpayer. In the case where qualified rehabilitation 
expenditures are treated as having been incurred by a taxpayer because 
of the application of paragraph (c)(3)(ii) of this section, the 
substantial rehabilitation test in paragraph (b)(3)(ii) of this section 
will be applied by aggregating the rehabilitation work done by the 
transferor and the transferee.
    (v) Examples. The provisions of this subparagraph (3) may be 
illustrated by the following examples:

    Example 1. Taxpayer A is the owner of a 30-year old building. The 
building is air conditioned by means of window air conditioning units. A 
replaces the window units with a central air conditioning system and no 
other rehabilitation is performed by A. The expenditures incurred by A 
did not materially extend the building's useful life, significantly 
upgrade its usefulness, or preserve it in a manner that significantly 
improves its condition or enhances its historic value. Although 
expenditures for replacement of window units with a central air 
conditioning system may constitute qualified expenditures as part of an 
overall rehabilitation, alone they do not qualify as a substantial 
rehabilitation and the building is not considered rehabilitated within 
the meaning of this subparagraph.
    Example 2. Taxpayer B is the owner of a 10 story office building 
that is 35 years old. The building is in substantial disrepair and in 
order to modernize it as an office building B installs new plumbing, 
electrical wiring, and heating and air conditioning systems. In 
addition, the layout of each floor is changed by means of tearing down 
many existing interior walls and partitions and building new walls, 
partitions, and doors. Old plaster is removed from many walls and 
replaced by new wall covering. New windows and new flooring are 
installed throughout the building. The improvements made by B materially 
extend the useful life of the building and significantly upgrade its 
usefulness. The building is considered rehabilitated within the meaning 
of the facts and circumstances test in this subparagraph.
    Example 3. Taxpayer C is the owner of a 100-year old building that 
has substantial historic character, although the building is not a 
certified historic structure (as defined in section 191(d)(1) and the 
regulations thereunder). C uncovers and restores the original woodwork, 
wall coverings and moldings throughout the building. The windows and 
doors are replaced with replicas of the original. The improvements made 
by C significantly preserve the building and significantly enhance its 
historic value. Thus, the building is considered rehabilitated within 
the meaning of this subparagraph.

    (4) Retention of 75 percent of external walls--(i) In general. A 
building meets the requirements set forth in paragraph (b)(1)(iii) only 
if 75 percent or more of the existing external walls (as measured by the 
total area of the existing external walls) are retained in place as 
external walls in the rehabilitation process. For this purpose, the area 
of existing external walls includes the area of windows and doors.
    (ii) External wall. For purposes of this paragraph (b)(4), a wall 
includes both the supporting elements of the wall and the nonsupporting 
elements (e.g., a curtain) of the wall. Except as otherwise provided in 
this paragraph (b)(4), the term ``external wall'' includes any wall that 
has one face exposed to the weather, earth, or an abutting wall erected 
on an adjacent property. An external wall also includes a shared wall

[[Page 372]]

(i.e., a single wall shared with an adjacent building), generally 
referred to as a ``party wall''.
    (iii) Alternative rule. Notwithstanding the definition of external 
wall contained in paragraph (b)(4)(ii) of this section, in any case in 
which the building being rehabilitated would fail to meet the 
requirements of a qualified rehabilitation building if the definition of 
external wall in paragraph (b)(4)(ii) of this section were used, then 
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.
    (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 is 
retained in place even though it is covered (e.g., with new siding). 
Moreover, the existing curtain may be 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. A wall may be disassembled and 
reassembled so long as the same supporting elements are used when the 
wall is reassembled. Thus, for example, in the case of the brick wall, 
the wall is considered retained in place even though the original bricks 
are removed (for cleaning, etc.) and put back to form the wall.
    (v) Retention as an external wall. For purposes of meeting the 75 
percent requirement of this subparagraph (4), an existing external wall 
must be retained in place as an external wall. If an addition is made 
that results in an existing external wall being converted into an 
internal wall, the wall is not retained in place as an external wall.
    (vi) Special rule. Solely for the purpose of meeting the 75 percent 
requirement of this subparagraph (4), 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, a wall of a light well in the center of 
an office building is not an external wall. However, walls surrounding 
an uncovered courtyard which is usable by the building's occupants, 
(e.g., at lunch time) are external walls.
    (vii) Examples. The provisions of this subparagraph (4) 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 studs). A covered the existing wood siding with aluminum 
siding in a part of a rehabilitation that otherwise qualified under this 
subparagraph. A satisfied the requirement that 75 percent of the 
existing external walls must be retained in place as external walls.
    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 
curtain were retained in place. B satisfied the requirement that 75 
percent of the existing external walls must be retained in place as 
external walls.
    Example 3. Taxpayer C rehabilitated a building which has two 
external walls measuring 75[foot] x 20[foot] and two other external 
walls measuring 100[foot] x 20[foot]. C tore down one of the larger 
walls, including its supporting elements, which accounted for more than 
25% of the building's external walls and constructed a new wall. C has 
not satisfied the requirement that 75 percent of the existing external 
walls must be retained in place as external walls.
    Example 4. The facts are the same as in example 3, except C does not 
tear down any walls, but makes an addition that results in one of the 
smaller walls becoming an internal wall. In addition, C enlarged 8 of 
the existing windows on the larger walls, increasing them from a size of 
3[foot] x 4[foot] to 6[foot] x 8[foot]. 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

[[Page 373]]

as external walls in the rehabilitation process. The enlargement of the 
existing windows on the larger wall does not change the result.

    (5) Major portion treated as separate building--(i) In general. 
Where there is a separate rehabilitation of a major portion of a 
building, such major portion shall be treated as a separate building. 
Thus, such major portion may qualify as a qualified rehabilitated 
building if the requirements of this paragraph are met with respect to 
such major portion. Expenditures for property that services both a major 
portion of a building and another portion must be specifically allocated 
to each portion to the extent possible. If it is not possible to make 
such an allocation, the expenditures must be allocated to each portion 
on some reasonable basis. What constitutes 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 would be the volume of 
the major portion served by the improvement relative to the volume of 
the other portion of the building served by the improvement.
    (ii) Major portion defined. Whether a part of a building constitutes 
a major portion of the building is determined upon the basis of all the 
facts and circumstances. A major portion must generally consist of 
clearly identifiable parts of a building (e.g., a wing of a building or 
the first 5 stories of a 7 story building). The following factors shall 
be taken into account:
    (A) Whether the portion comprises an entire leasehold interest or an 
entire ownership (e.g., condominium) interest;
    (B) Whether the portion (as measured by volume) is sufficiently 
large that it would be reasonable to treat it as a separate building; 
and
    (C) Whether the portion is functionally different from other parts 
of the building.
    (6) Special rule for rehabilitation done in phases. If 
rehabilitation which is not continuous is determined under this 
subparagraph to be a single rehabilitation done in phases, the 
requirements of this paragraph (b) are to be applied with respect to the 
overall rehabilitation and not merely to a phase of the rehabilitation. 
In such case, a phase of a single overall rehabilitation will not be 
considered as ``prior rehabilitation'' for purposes of subparagraph 
(2)(i)(B) of this paragraph (b). Whether rehabilitation which is not 
continuous is a single rehabilitation that is done in phases is 
determined on the basis of all the facts and circumstances. Generally, 
however, to constitute a single rehabilitation that is done in phases, 
there must exist, prior to the time any rehabilitation work is 
commenced, a set of written plans describing generally all phases of the 
rehabilitation of the building and a reasonable expectation that all 
phases of the rehabilitation will be completed. Such written plans are 
not required to contain detailed working drawings or detailed 
specifications of the material to be used. In addition, the period 
between the time that physical work on the first phase of the overall 
rehabilitation begins and physical work on the last phase of the overall 
rehabilitation begins must be reasonable. In determining whether the 
rehabilitation is completed within a reasonable time, the fact that a 
building is occupied during the rehabilitation, the necessity of 
acquiring a lease (of additional portions of the building), and 
unforeseen delays shall be taken into account. Other factors that are 
relevant in determining whether rehabilitation is a single 
rehabilitation include the length of time between each phase of 
rehabilitation activities and the extent of rehabilitation activity in 
each phase.
    (7) 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 all of the 
requirements of a qualified rehabilitated building in section 48(g)(1) 
and this section may be applied to the constituent adjoining buildings 
in the aggregate. Any party walls or abutting walls between the 
constitutent buildings that would otherwise be treated as external walls 
(within the meaning of paragraph (b)(4)(ii) of this section) would not 
be

[[Page 374]]

treated as external walls of the building; the substantial 
rehabilitation test in paragraph (b)(3)(ii) of this section would be 
applied to the aggregate rehabilitation work with respect to all of the 
constitutent buildings.
    (c) Definition of qualified rehabilitation expenditures--(1) In 
general. Except as provided in subparagraph (2) of this paragraph, the 
term ``qualified rehabilitation expenditure'' means any amount--
    (i) Properly chargeable to capital account (as described in 
subparagraph (2) of this paragraph),
    (ii) Incurred after October 31, 1978, for depreciable or amortizable 
property (or additions or improvements to property) with a useful life 
of five years or more, and
    (iii) Made in connection with the rehabilitation of a qualified 
rehabilitated building.
    (2) Chargeable to capital account. For purposes of paragraph 
(c)(1)(i) of this section, amounts paid or incurred are chargeable to 
capital account if under the taxpayer's method of accounting they are 
property includible in computing basis under Sec. 1.46-3. Amounts 
treated as an expense and deducted in the year they are paid or incurred 
are not chargeable to capital account.
    (3) Incurred by the taxpayer--(i) In general. Generally, to qualify 
for a credit under section 48 (a)(1)(E), qualified rehabilitation 
expenditures must be incurred by the taxpayer after October 31, 1978. An 
expenditure is incurred for purposes of this paragraph on the date such 
expenditure would be considered incurred under the 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. (A) Where rehabilitation expenditures are incurred with 
respect to a building by a person (or persons) other than the taxpayer 
and the taxpayer acquires the building, or a portion of the building to 
which the expenditures are allocable, the taxpayer acquiring such 
property will be treated as having incurred the rehabilitation 
expenditures actually incurred by the transferor (or treated as incurred 
by the transferor under this paragraph (c)(3)(ii)) with respect to the 
acquired property, provided that--
    (1) The building, or the portion of the building, acquired by the 
taxpayer was not used after the rehabilitation expenditures were 
incurred and prior to the date of acquisition by the taxpayer, and
    (2) No credit with respect to such qualified rehabilitation 
expenditures is claimed by anyone other than the taxpayer acquiring the 
property.

For purposes of this paragraph (c)(3)(ii), use shall mean actual use, 
whether personal or business.
    (B) The amount of qualified rehabilitation expenditures treated as 
incurred by the taxpayer under this paragraph is the lesser of--
    (1) The qualified rehabilitation expenditures incurred before the 
date on which the taxpayer acquired the building (or portion thereof), 
to which the expenditures are attributable, or
    (2) That portion of the taxpayer's cost or other basis for the 
property which is attributable to the qualified rehabilitation 
expenditures described in paragraph (c)(3)(B)(1) of this section 
incurred before such date.

For purposes of paragraph (c)(6)(ii) of this section, the amount of 
rehabilitation expenditures treated as incurred by the taxpayer under 
this paragraph (c)(3)(ii) shall not be considered to be part of the cost 
of acquiring a building or any interest in the building. The portion of 
the cost of acquiring a building (or an interest therein) which is not 
treated under this paragraph as qualified rehabilitation expenditures 
incurred by the taxpayer is not eligible for a rehabilitation investment 
credit. See paragraph (c)(6)(ii) of this section.
    (C) See paragraph (b)(2)(iv) of this section for rules concerning 
the application of the substantial rehabilitation test to expenditures 
treated as incurred by the taxpayer.

[[Page 375]]

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

    Example 1. In 1978, taxpayer A, a cash basis taxpayer, commenced the 
rehabilitation of a 30-year old building. In June 1978, A signed 
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 September 1978, but A did not pay 
the amount due until November 1, 1978. The expenditures for the plumbing 
are not qualified rehabilitation expenditures because they were not 
incurred after October 31, 1978.
    Example 2. B incurred qualified rehabilitation expenditures of 
$300,000 with respect to an existing building between January 1, 1980, 
and May 15, 1980, and then sold the building to C on June 1, 1980. If 
the property attributable to the expenditures was not placed in service 
by A during the period from January 1, 1980, to June 1, 1980, C will be 
treated as having incurred the expenditures.

    (4) Incurred for 5-year property. An expenditure is incurred for 
depreciable or amortizable property if the amount of the expenditure is 
added to the basis of property which is depreciable or amortizable under 
section 167. The determination of whether property has a useful life of 
five years or more is made by applying the principles of Sec. 1.46-3(e). 
In the case of expenditures for property made by a lessee, see sections 
167 and 178 and the regulations thereunder for rules relating to whether 
improvements made to leased property are depreciable or amortizable.
    (5) Made in connection with the rehabilitation of a qualified 
rehabilitated building. Expenditures attributable to work done to 
facilities related to a building (e.g., sidewalk, parking lot, 
landscaping) are not considered made in connection with a rehabilitation 
of a qualified rehabilitated building.
    (6) Certain expenditures excluded from qualified rehabilitation 
expenditures. The term ``qualified rehabilitation expenditures'' does 
not include the following expenditures:
    (i) An expenditure for property which is ``section 38 property'' 
(determined without regard to section 48(a)(1) (E) and (l)).
    (ii) The cost of acquiring a building or any interest in a building 
(including a leasehold interest) except as provided in paragraph 
(c)(3)(ii) of this section.
    (iii) An expenditure attributable to enlargement of a building (as 
defined in paragraph (c)(7) of this section).
    (iv) An expenditure attributable to rehabilitation of a certified 
historic structure (as defined in section 191(d)(1) and the regulations 
thereunder), unless the rehabilitation is a certified rehabilitation (as 
defined in paragraph (c)(8) of this section).
    (7) Expenditures for enlargement distinguished--(i) In general. 
Expenditures attributable to an enlargement of an existing building do 
not qualify as qualified rehabilitated expenditures. 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 considred an enlargement. Generally, the total volume of a 
building is 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. In addition, a building is enlarged to the extent of any 
construction outside the exterior faces of the existing external wall of 
the building.
    (ii) Rehabilitation which includes enlargement. If expenditures for 
property only partially qualify as qualified rehabilitation expenditures 
because some of the expenditures are also attributable to the 
enlargement of the building, the expenditures must be apportioned 
between the original portion of the building and the enlargement. This 
allocation should be made using the principles contained in paragraph 
(b)(5)(i) of this section.
    (8) Certified rehabilitation--(i) In general. For the purpose of 
this paragraph (c) of this section, the term ``certified 
rehabilitation'' means any rehabilitation of a certified historic 
building in a registered historic district which the Secretary of the 
Interior has certified to the Secretary as being consistent with the 
historic character of such building or the district in which such 
building is located.

[[Page 376]]

    (ii) Revoked or invalidated certifications. If the Department of 
Interior revokes or otherwise invalidates a certification after it has 
been provided to a taxpayer, the decertified property will cease to be 
section 38 property described in section 48(a)(1)(e). Such cessation 
shall be effective as of the date the activity giving rise to the 
revocation or invalidation occurred. See section 47 for the rules 
applicable to property that ceases to be section 38 property.
    (d) Coordination with other provisions of the Code--(1) Credit by 
lessees--(i) Rehabilitation performed by lessor. A lessee may take the 
credit for rehabilitation performed by the lessor if the requirements of 
this section and section 48(d) are satisfied. For purposes of applying 
section 48(d), the fair market value of section 38 property described in 
section 48(a)(1)(E) shall be equal to that portion of the lessor's basis 
in a qualified rehabilitated building that is attributable to qualified 
rehabilitation expenditures.
    (ii) Rehabilitation performed by lessee. A lessee may take the 
credit for rehabilitation performed by the lessee, provided that the 
property (or improvements or additions to property) for which the 
rehabilitation expenditures are made is depreciable (or amortizable) by 
the lessee (see sections 167 and 178, and the regulations thereunder) 
and the requirements of this section are satisfied.
    (2) When credit may be claimed. The investment credit for qualified 
rehabilitation expenditures is allowed generally in the taxable year in 
which the property to which the rehabilitation expenditures is 
attributable is placed in service, provided the building is a qualified 
rehabilitated building for the taxable year. See Sec. 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 Sec. 1.46-
5 (relating to qualified progress expenditures).
    (3) Recapture. If property described in section 48(a)(1)(E) is 
disposed of by the taxpayer, or otherwise ceases to be ``section 38 
property,'' recapture may result under section 47. Property will cease 
to be section 38 property, and therefore recapture may occur under 
section 47, in any case where the Department of Interior revokes or 
otherwise invalidates a certification of rehabilitation (see section 
48(g)(2)(C)) after the property is placed in service because, for 
example, the taxpayer made modifications to the building inconsistent 
with Department of Interior standards.
    (e) Effective date--(1) General rule. Except as provided in 
paragraph (e)(2) of this section, this Sec. 1.48-11 shall not apply to 
expenditures incurred after December 31, 1981.
    (2) Transitional rule. This Sec. 1.48-11 shall continue to apply to 
expenditures incurred after December 31, 1981, for the rehabilitation of 
a building if--
    (i) The physical work on the rehabilitation began before January 1, 
1982, and
    (ii) The building does not meet the requirements of section 48(g)(1) 
of the Code as amended by the Economic Recovery Tax Act of 1981.
