    CHAPTER I--INTERNAL REVENUE SERVICE, DEPARTMENT OF THE TREASURY 
                               (CONTINUED)
 
PART 1_INCOME TAXES--Table of Contents
 
Sec. 1.168(k)-1T  Additional first year depreciation deduction (temporary).

    (a) Scope and definitions--(1) Scope. This section provides the 
rules for determining the 30-percent additional first year depreciation 
deduction allowable under section 168(k)(1) for qualified property and 
the 50-percent additional first year depreciation deduction allowable 
under section 168(k)(4) for 50-percent bonus depreciation property.
    (2) Definitions. For purposes of section 168(k) and this section, 
the following definitions apply:
    (i) Depreciable property is property that is of a character subject 
to the allowance for depreciation as determined under section 167 and 
the regulations thereunder.
    (ii) MACRS property is tangible, depreciable property that is placed 
in service after December 31, 1986 (or after July 31, 1986, if the 
taxpayer made an election under section 203(a)(1)(B) of the Tax Reform 
Act of 1986; 100 Stat. 2143) and subject to section 168, except for 
property excluded from the application of section 168 as a result of 
section 168(f) or as a result of a transitional rule.
    (iii) Unadjusted depreciable basis is the basis of property for 
purposes of section 1011 without regard to any adjustments described in 
section 1016(a)(2) and (3). This basis reflects the reduction in basis 
for the percentage of the taxpayer's use of property for the taxable 
year other than in the taxpayer's trade or business (or for the 
production of income), for any portion of the basis the taxpayer 
properly elects to treat as an expense under section 179, and for any 
adjustments to basis provided by other provisions of the Internal 
Revenue Code and the regulations thereunder (other than section 
1016(a)(2) and (3)) (for example, a reduction in basis by the amount of 
the disabled access credit pursuant to section 44(d)(7)). For property 
subject to a lease, see section 167(c)(2).
    (iv) Adjusted depreciable basis is the unadjusted depreciable basis 
of the property, as defined in Sec. 1.168(k)-1T(a)(2)(iii), less the 
adjustments described in section 1016(a)(2) and (3).
    (b) Qualified property or 50-percent bonus depreciation property--
(1) In general. Qualified property or 50-percent bonus depreciation 
property is depreciable property that--
    (i) Meets the requirements in Sec. 1.168(k)-1T(b)(2) (description 
of property);
    (ii) Meets the requirements in Sec. 1.168(k)-1T(b)(3) (original 
use);

[[Page 1086]]

    (iii) Meets the requirements in Sec. 1.168(k)-1T(b)(4) (acquisition 
of property); and
    (iv) Meets the requirements in Sec. 1.168(k)-1T(b)(5) (placed-in-
service date).
    (2) Description of qualified property or 50-percent bonus 
depreciation property--(i) In general. Depreciable property will meet 
the requirements of this paragraph (b)(2) if the property is--
    (A) MACRS property (as defined in Sec. 1.168(k)-1T(a)(2)(ii)) that 
has a recovery period of 20 years or less. For purposes of this 
paragraph (b)(2)(i)(A) and section 168(k)(2)(B)(i)(II) and 168(k)(4)(C), 
the recovery period is determined in accordance with section 168(c) 
regardless of any election made by the taxpayer under section 168(g)(7);
    (B) Computer software as defined in, and depreciated under, section 
167(f)(1) and the regulations thereunder;
    (C) Water utility property as defined in section 168(e)(5) and 
depreciated under section 168; or
    (D) Qualified leasehold improvement property as defined in paragraph 
(c) of this section and depreciated under section 168.
    (ii) Property not eligible for additional first year depreciation 
deduction--(A) Property that is not qualified property. For purposes of 
the 30-percent additional first year depreciation deduction, depreciable 
property will not meet the requirements of this paragraph (b)(2) if the 
property is--
    (1) Described in section 168(f);
    (2) Required to be depreciated under the alternative depreciation 
system of section 168(g) pursuant to section 168(g)(1)(A) through (D) or 
other provisions of the Internal Revenue Code (for example, property 
described in section 263A(e)(2)(A) or section 280F(b)(1));
    (3) Included in any class of property for which the taxpayer elects 
not to deduct the 30-percent additional first year depreciation (for 
further guidance, see paragraph (e) of this section); or
    (4) Qualified New York Liberty Zone leasehold improvement property 
as defined in section 1400L(c)(2).
    (B) Property that is not 50-percent bonus depreciation property. For 
purposes of the 50-percent additional first year depreciation deduction, 
depreciable property will not meet the requirements of this paragraph 
(b)(2) if the property is--
    (1) Described in paragraph (b)(2)(ii)(A)(1), (2), or (4) of this 
section; or
    (2) Included in any class of property for which the taxpayer elects 
the 30-percent, instead of the 50-percent, additional first year 
depreciation deduction or elects not to deduct any additional first year 
depreciation (for further guidance, see paragraph (e) of this section).
    (3) Original use--(i) In general. For purposes of the 30-percent 
additional first year depreciation deduction, depreciable property will 
meet the requirements of this paragraph (b)(3) if the original use of 
the property commences with the taxpayer after September 10, 2001. For 
purposes of the 50-percent additional first year depreciation deduction, 
depreciable property will meet the requirements of this paragraph (b)(3) 
if the original use of the property commences with the taxpayer after 
May 5, 2003. Except as provided in paragraph (b)(3)(iii) and (iv) of 
this section, original use means the first use to which the property is 
put, whether or not that use corresponds to the use of the property by 
the taxpayer. Thus, additional capital expenditures incurred by a 
taxpayer to recondition or rebuild property acquired or owned by the 
taxpayer satisfies the original use requirement. However, the cost of 
reconditioned or rebuilt property acquired by the taxpayer does not 
satisfy the original use requirement. The question of whether property 
is reconditioned or rebuilt property is a question of fact. For purposes 
of this paragraph (b)(3)(i), property that contains used parts will not 
be treated as reconditioned or rebuilt if the cost of the used parts is 
not more than 20 percent of the total cost of the property.
    (ii) Conversion to business or income-producing use. If a taxpayer 
initially acquires new property for personal use and subsequently uses 
the property in the taxpayer's trade or business or for the taxpayer's 
production of income, the taxpayer is considered as the original user of 
the property. If a person initially acquires new property for personal 
use and a taxpayer subsequently

[[Page 1087]]

acquires the property from the person for use in the taxpayer's trade or 
business or for the taxpayer's production of income, the taxpayer is not 
considered the original user of the property.
    (iii) Sale-leaseback and syndication transactions--(A) Sale-
leaseback transaction. If new property is originally placed in service 
by a person after September 10, 2001 (for qualified property), or after 
May 5, 2003 (for 50-percent bonus depreciation property), and is sold to 
a taxpayer and leased back to the person by the taxpayer within three 
months after the date the property was originally placed in service by 
the person, the taxpayer-lessor is considered the original user of the 
property.
    (B) Syndication transaction. If new property is originally placed in 
service by a lessor (including by operation of paragraph (b)(5)(ii)(A) 
of this section) after September 10, 2001 (for qualified property), or 
after May 5, 2003 (for 50-percent bonus depreciation property), and is 
sold by the lessor or any subsequent purchaser within three months after 
the date the property was originally placed in service by the lessor, 
and the user of the property after the last sale during the three-month 
period remains the same as when the property was originally placed in 
service by the lessor, the purchaser of the property in the last sale 
during the three-month period is considered the original user of the 
property.
    (C) Sale-leaseback transaction followed by a syndication 
transaction. If a sale-leaseback transaction that satisfies the 
requirements in paragraph (b)(3)(iii)(A) of this section is followed by 
a syndication transaction that satisfies the requirements in paragraph 
(b)(3)(iii)(B) of this section, the original user of the property is 
determined in accordance with paragraph (b)(3)(iii)(B) of this section.
    (iv) Fractional interests in property. If, in the ordinary course of 
its business, a taxpayer sells fractional interests in property to 
unrelated third parties, each first fractional owner of the property is 
considered as the original user of its proportionate share of the 
property. Furthermore, if the taxpayer uses the property before all of 
the fractional interests of the property are sold but the property 
continues to be held primarily for sale by the taxpayer, the original 
use of any fractional interest sold to an unrelated third party 
subsequent to the taxpayer's use of the property begins with the first 
purchaser of that fractional interest. For purposes of this paragraph 
(b)(3)(iv), persons are not related if they do not have a relationship 
described in section 267(b) or 707(b) and the regulations thereunder.
    (v) Examples. The application of this paragraph (b)(3) is 
illustrated by the following examples:

    Example 1. On August 1, 2002, A buys from B for $20,000 a machine 
that has been previously used by B in B's trade or business. On March 1, 
2003, A makes a $5,000 capital expenditure to recondition the machine. 
The $20,000 purchase price does not qualify for the additional first 
year depreciation deduction because the original use requirement of this 
paragraph (b)(3) is not met. However, the $5,000 expenditure satisfies 
the original use requirement of this paragraph (b)(3) and, assuming all 
other requirements are met, qualifies for the 30-percent additional 
first year depreciation deduction, regardless of whether the $5,000 is 
added to the basis of the machine or is capitalized as a separate asset.
    Example 2. C, an automobile dealer, uses some of its automobiles as 
demonstrators in order to show them to prospective customers. The 
automobiles that are used as demonstrators by C are held by C primarily 
for sale to customers in the ordinary course of its business. On 
September 1, 2002, D buys from C an automobile that was previously used 
as a demonstrator by C. D will use the automobile solely for business 
purposes. The use of the automobile by C as a demonstrator does not 
constitute a ``use'' for purposes of the original use requirement and, 
therefore, D will be considered the original user of the automobile for 
purposes of this paragraph (b)(3). Assuming all other requirements are 
met, D's purchase price of the automobile qualifies for the 30-percent 
additional first year depreciation deduction for D, subject to any 
limitation under section 280F.
    Example 3. On April 1, 2000, E acquires a horse to be used in E's 
thoroughbred racing business. On October 1, 2003, F buys the horse from 
E and will use the horse in F's horse breeding business. The use of the 
horse by E in its racing business prevents the original use of the horse 
from commencing with F. Thus, F's purchase price of the horse does not 
qualify for the additional first year depreciation deduction.
    Example 4. In the ordinary course of its business, G sells 
fractional interests in its aircraft to unrelated parties. G holds out 
for

[[Page 1088]]

sale eight equal fractional interests in an aircraft. On January 1, 
2003, G sells five of the eight fractional interests in the aircraft to 
H, an unrelated party, and H begins to use its proportionate share of 
the aircraft immediately upon purchase. On June 1, 2003, G sells to I, 
an unrelated party to G and H, the remaining unsold 3/8 fractional 
interests in the aircraft. H is considered the original user as to its 
5/8 fractional interest in the aircraft and I is considered the original 
user as to its 3/8 fractional interest in the aircraft. Thus, assuming 
all other requirements are met, H's purchase price for its 5/8 
fractional interest in the aircraft qualifies for the 30-percent 
additional first year depreciation deduction and I's purchase price for 
its 3/8 fractional interest in the aircraft qualifies for the 50-percent 
additional first year depreciation deduction.

    (4) Acquisition of property--(i) In general--(A) Qualified property. 
For purposes of the 30-percent additional first year depreciation 
deduction, depreciable property will meet the requirements of this 
paragraph (b)(4) if the property is--
    (1) Acquired by the taxpayer after September 10, 2001, and before 
January 1, 2005, but only if no written binding contract for the 
acquisition of the property was in effect before September 11, 2001; or
    (2) Acquired by the taxpayer pursuant to a written binding contract 
that was entered into after September 10, 2001, and before January 1, 
2005.
    (B) 50-percent bonus depreciation property. For purposes of the 50-
percent additional first year depreciation deduction, depreciable 
property will meet the requirements of this paragraph (b)(4) if the 
property is acquired by the taxpayer after May 5, 2003, and before 
January 1, 2005, but only if no written binding contract for the 
acquisition of the property was in effect before May 6, 2003.
    (ii) Definition of binding contract--(A) In general. A contract is 
binding only if it is enforceable under State law against the taxpayer 
or a predecessor, and does not limit damages to a specified amount (for 
example, by use of a liquidated damages provision). For this purpose, a 
contractual provision that limits damages to an amount equal to at least 
5 percent of the total contract price will not be treated as limiting 
damages to a specified amount. In determining whether a contract limits 
damages, the fact that there may be little or no damages because the 
contract price does not significantly differ from fair market value will 
not be taken into account. For example, if a taxpayer entered into an 
irrevocable written contract to purchase an asset for $100 and the 
contract contained no provision for liquidated damages, the contract is 
considered binding notwithstanding the fact that the asset had a fair 
market value of $99 and under local law the seller would only recover 
the difference in the event the purchaser failed to perform. If the 
contract provided for a full refund of the purchase price in lieu of any 
damages allowable by law in the event of breach or cancellation by the 
seller, the contract is not considered binding.
    (B) Conditions. A contract is binding even if subject to a 
condition, as long as the condition is not within the control of either 
party or a predecessor. A contract will continue to be binding if the 
parties make insubstantial changes in its terms and conditions or 
because any term is to be determined by a standard beyond the control of 
either party. A contract that imposes significant obligations on the 
taxpayer or a predecessor will be treated as binding notwithstanding the 
fact that insubstantial terms remain to be negotiated by the parties to 
the contract.
    (C) Options. An option to either acquire or sell property is not a 
binding contract.
    (D) Supply agreements. A binding contract does not include a supply 
or similar agreement if the amount and design specifications of the 
property to be purchased have not been specified. The contract will not 
be a binding contract for the property to be purchased until both the 
amount and the design specifications are specified. For example, if the 
provisions of a supply or similar agreement state the design 
specifications of, and the pricing for, the property to be purchased, a 
purchase order under the agreement for a specific number of assets is 
treated as a binding contract.
    (E) Components. A binding contract to acquire one or more components 
of a larger property will not be treated as a binding contract to 
acquire the larger

[[Page 1089]]

property. If a binding contract to acquire the component does not 
satisfy the requirements of this paragraph (b)(4), the component does 
not qualify for the 30-percent or 50-percent additional first year 
depreciation deduction, as applicable.
    (iii) Self-constructed property--(A) In general. If a taxpayer 
manufactures, constructs, or produces property for use by the taxpayer 
in its trade or business (or for its production of income), the 
acquisition rules in paragraph (b)(4)(i) of this section are treated as 
met for qualified property if the taxpayer begins manufacturing, 
constructing, or producing the property after September 10, 2001, and 
before January 1, 2005, and for 50-percent bonus depreciation property 
if the taxpayer begins manufacturing, constructing, or producing the 
property after May 5, 2003, and before January 1, 2005. Property that is 
manufactured, constructed, or produced for the taxpayer by another 
person under a written binding contract (as defined in paragraph 
(b)(4)(ii) of this section) that is entered into prior to the 
manufacture, construction, or production of the property for use by the 
taxpayer in its trade or business (or for its production of income) is 
considered to be manufactured, constructed, or produced by the taxpayer.
    (B) When does construction begin. For purposes of paragraph 
(b)(4)(iii) of this section, construction of property begins when 
physical work of a significant nature begins. Physical work does not 
include preliminary activities such as planning or designing, securing 
financing, exploring, or researching. The determination of when physical 
work of a significant nature begins depends on the facts and 
circumstances. For purposes of this paragraph (b)(4)(iii)(B), physical 
work of a significant nature will not be considered to begin before the 
taxpayer incurs (in the case of an accrual basis taxpayer) or pays (in 
the case of a cash basis taxpayer) more than 10 percent of the total 
cost of the property (excluding the cost of any land and preliminary 
activities such as planning or designing, securing financing, exploring, 
or researching). For example, if a retail motor fuels outlet is to be 
constructed on-site, construction begins when physical work of a 
significant nature commences at the site; that is, when work begins on 
the excavation for footings, pouring the pads for the outlet, or the 
driving of foundation pilings into the ground. Preliminary work, such as 
clearing a site, test drilling to determine soil condition, or excation 
to change the contour of the land (as distinguished from excavation for 
footings) does not constitute the beginning of construction. However, if 
a retail motor fuels outlet is to be assembled on-site from modular 
units constructed off-site and delivered to the site where the outlet 
will be used, construction begings when physical work of a significant 
nature commences at the off-site location.
    (C) Components of self-constructed property--(1) Acquired 
components. If a binding contract (as defined in paragraph (b)(4)(ii) of 
this section) to acquire a component does not satisfy the requirements 
of paragraph (b)(4)(i) of this section, the component does not qualify 
for the 30-percent or 50-percent additional first year depreciation 
deduction, as applicable. A binding contract (as defined in paragraph 
(b)(4)(ii) of this section) to acquire one or more components of a 
larger self-constructed property will not preclude the larger self-
constructed property from satisfying the acquisition rules in paragraph 
(b)(4)(iii)(A) of this section. Accordingly, the unadjusted depreciable 
basis of the larger self-constructed property that is eligible for the 
30-percent or 50-percent additional first year depreciation deduction, 
as applicable (assuming all other requirements are met), must not 
include the unadjusted depreciable basis of any component that does not 
satisfy the requirements of paragraph (b)(4)(i) of this section. If the 
manufacture, construction, or production of the larger self-constructed 
property begins before September 11, 2001, for qualified property, or 
before May 6, 2003, for 50-percent bonus depreciation property, the 
larger self-constructed property and any acquired components related to 
the larger self-constructed property do not qualify for the 30-percent 
or 50-percent additional first year depreciation deduction, as 
applicable. If a binding contract to acquire the component is entered 
into

[[Page 1090]]

after September 10, 2001, for qualified property, or after May 5, 2003, 
for 50-percent bonus depreciation property, and before January 1, 2005, 
but the manufacture, construction, or production of the larger self-
constructed property does not begin before January 1, 2005, the 
component qualifies for the additional first year depreciation deduction 
(assuming all other requirements are met) but the larger self-
constructed property does not.
    (2) Self-constructed components. If the manufacture, construction, 
or production of a component does not satisfy the requirements of 
paragraph (b)(4)(iii)(A) of this section, the component does not qualify 
for the 30-percent or 50-percent additional first year depreciation 
deduction, as applicable. However, if the manufacture, construction, or 
production of a component does not satisfy the requirements of paragraph 
(b)(4)(iii)(A) of this section, but the manufacture, construction, or 
production of the larger self-constructed property satisfies the 
requirements of paragraph (b)(4)(iii)(A) of this section, the larger 
self-constructed property qualifies for the 30-percent or 50-percent 
additional first year depreciation deduction, as applicable (assuming 
all other requirements are met) even though the component does not 
qualify for the 30-percent or 50-percent additional first year 
depreciation deduction. Accordingly, the unadjusted depreciable basis of 
the larger self-constructed property that is eligible for the 30-percent 
or 50-percent additional first year depreciation deduction, as 
applicable (assuming all other requirements are met), must not include 
the unadjusted depreciable basis of any component that does not qualify 
for the 30-percent or 50-percent additional first year depreciation 
deduction. If the manufacture, construction, or production of the larger 
self-constructed property began before September 11, 2001, for qualified 
property, or before May 6, 2003, for 50-percent bonus depreciation 
property, the larger self-constructed property and any self-constructed 
components related to the larger self-constructed property do not 
qualify for the 30-percent or 50-percent additional first year 
depreciation deduction, as applicable. If the manufacture, construction, 
or production of a component begins after September 10, 2001, for 
qualified property, or after May 5, 2003, for 50-percent bonus 
depreciation property, and before January 1, 2005, but the manufacture, 
construction, or production of the larger self-constructed property does 
not begin before January 1, 2005, the component qualifies for the 
additional first year depreciation deduction (assuming all other 
requirements are met) but the larger self-constructed property does not.
    (iv) Disqualified transactions--(A) In general. Property does not 
satisfy the requirements of this paragraph (b)(4) if the user of the 
property as of the date on which the property was originally placed in 
service (including by operation of paragraph (b)(5)(ii), (iii), and (iv) 
of this section), or a related party to the user, acquired, or had a 
written binding contract (as defined in paragraph (b)(4)(ii) of this 
section) in effect for the acquisition of, the property at any time 
before September 11, 2001 (for qualified property), or before May 6, 
2003 (for 50-percent bonus depreciation property). In addition, property 
manufactured, constructed, or produced for the taxpayer or a related 
party does not satisfy the requirements of this paragraph (b)(4) if the 
manufacture, construction, or production of the property for the 
taxpayer or a related party began at any time before September 11, 2001 
(for qualified property), or before May 6, 2003 (for 50-percent bonus 
depreciation property).
    (B) Related party defined. For purposes of this paragraph 
(b)(4)(iv), persons are related if they have a relationship specified in 
section 267(b) or 707(b) and the regulations thereunder.
    (v) Examples. The application of this paragraph (b)(4) is 
illustrated by the following examples:

    Example 1. On September 1, 2001, J, a corporation, entered into a 
written agreement with K, a manufacturer, to purchase 20 new lamps for 
$100 each within the next two years. Although the agreement specifies 
the number of lamps to be purchased, the agreement does not specify the 
design of the lamps to be purchased. Accordingly, the agreement is not a 
binding contract pursuant to paragraph (b)(4)(ii)(D) of this section.
    Example 2. Same facts as Example 1. On December 1, 2001, J placed a 
purchase order with K to purchase 20 new model XPC5 lamps for

[[Page 1091]]

$100 each for a total amount of $2,000. Because the agreement specifies 
the number of lamps to be purchased and the purchase order specifies the 
design of the lamps to be purchased, the purchase order placed by J with 
K on December 1, 2001, is a binding contract pursuant to paragraph 
(b)(4)(ii)(D) of this section. Accordingly, the cost of the 20 lamps 
qualifies for the 30-percent additional first year depreciation 
deduction.
    Example 3. Same facts as Example 1 except that the written agreement 
between J and K is to purchase 100 model XPC5 lamps for $100 each within 
the next two years. Because this agreement specifies the amount and 
design of the lamps to be purchased, the agreement is a binding contract 
pursuant to paragraph (b)(4)(ii)(D) of this section. Accordingly, 
because the agreement was entered into before September 11, 2001, any 
lamp acquired by J under this contract does not qualify for the 
additional first year depreciation deduction.
    Example 4. On September 1, 2001, L began constructing an electric 
generation power plant for its own use. On November 1, 2002, L ceases 
construction of the power plant prior to its completion. Between 
September 1, 2001, and November 1, 2002, L incurred $3,000,000 for the 
construction of the power plant. On May 6, 2003, L resumed construction 
of the power plant and completed its construction on August 31, 2003. 
Between May 6, 2003, and August 31, 2003, L incurred another $1,600,000 
to complete the construction of the power plant and, on September 1, 
2003, L placed the power plant in service. None of L's total 
expenditures of $4,600,000 qualify for the additional first year 
depreciation deduction because, pursuant to paragraph (b)(4)(iii)(A) of 
this section, L began constructing the power plant before September 11, 
2001.
    Example 5. Same facts as Example 4 except that L began constructing 
the electric generation power plant for its own use on October 1, 2001. 
L's total expenditures of $4,600,000 qualify for the additional first 
year depreciation deduction because, pursuant to paragraph 
(b)(4)(iii)(A) of this section, L began constructing the power plant 
after September 10, 2001, and placed the power plant in service before 
January 1, 2005. Accordingly, the additional first year depreciation 
deduction for the power plant will be $1,380,000, computed as $4,600,000 
multiplied by 30 percent.
    Example 6. On August 1, 2001, M entered into a written binding 
contract to acquire a new turbine. The new turbine is a component part 
of a new electric generation power plant that is being constructed on 
M's behalf. The construction of the new electric generation power plant 
commenced in November 2001, and the new electric generation power plant 
was completed in November 2002. Because M entered into a written binding 
contract to acquire a component part (the new turbine) prior to 
September 11, 2001, pursuant to paragraph (b)(4)(iii)(C) of this 
section, the component part does not qualify for the additional first 
year depreciation deduction. However, pursuant to paragraphs 
(b)(4)(iii)(A) and (C) of this section, the new plant constructed for M 
will qualify for the 30-percent additional first year depreciation 
deduction because construction of the new plant began after September 
10, 2001, and before May 6, 2003. Accordingly, the unadjusted 
depreciable basis of the new plant that is eligible for the 30-percent 
additional first year depreciation deduction must not include the 
unadjusted depreciable basis of the new turbine.
    Example 7. Same facts as Example 6 except that M entered into the 
written binding contract to acquire the new turbine on September 30, 
2002, and construction of the new plant commenced on August 1, 2001. 
Because M began construction of the new plant prior to September 11, 
2001, pursuant to paragraphs (b)(4)(iii)(A) and (C) of this section, 
neither the new plant constructed for M nor the turbine will qualify for 
the additional first year depreciation deduction because self-
construction of the new plant began prior to September 11, 2001.
    Example 8. On September 1, 2001, N began constructing property for 
its own use. On October 1, 2001, N sold its rights to the property to O, 
a related party under section 267(b). Pursuant to paragraph (b)(4)(iv) 
of this section, the property is not eligible for the additional first 
year depreciation deduction because N and O are related parties and 
construction of the property by N began prior to September 11, 2001.
    Example 9. On September 1, 2001, P entered into a written binding 
contract to acquire property. On October 1, 2001, P sold its rights to 
the property to Q, a related party under section 267(b). Pursuant to 
paragraph (b)(4)(iv) of this section, the property is not eligible for 
the additional first year depreciation deduction because P and Q are 
related parties and a written binding contract for the acquisition of 
the property was in effect prior to September 11, 2001.
    Example 10. Prior to September 11, 2001, R began constructing an 
electric generation power plant for its own use. On May 1, 2003, prior 
to the completion of the power plant, R transferred the rights to own 
and use this power plant to S, an unrelated party, for $6,000,000. 
Between May 6, 2003, and June 30, 2003, S, a calendar-year taxpayer, 
incurred another $1,200,000 to complete the construction of the power 
plant and, on August 1, 2003, S placed the power plant in service. 
Because R and S are not related parties, the transaction between R and S 
will not be a disqualified transaction pursuant to paragraph (b)(4)(iv) 
of this section. Accordingly, S's total expenditures of $7,200,000 for 
the power plant qualify for the additional first year depreciation 
deduction. S's additional

[[Page 1092]]

first year depreciation deduction for the power plant will be 
$2,400,000, computed as $6,000,000 multiplied by 30 percent, plus 
$1,200,000 multiplied by 50 percent. The $6,000,000 portion of the total 
$7,200,000 unadjusted depreciable basis qualifies for the 30-percent 
additional first year depreciation deduction because that portion of the 
total unadjusted depreciable basis was acquired by S after September 10, 
2001, and before May 6, 2003. However, because S began construction to 
complete the power plant after May 5, 2003, the $1,200,000 portion of 
the total $7,200,000 unadjusted depreciable basis qualifies for the 50-
percent additional first year depreciation deduction.
    Example 11. On September 1, 2001, T acquired and placed in service 
equipment. On October 15, 2001, T sells the equipment to U, an unrelated 
party, and leases the property back from U in a sale-leaseback 
transaction. Pursuant to paragraph (b)(4)(iv) of this section, the 
equipment does not qualify for the additional first year depreciation 
deduction because T, the user of the equipment, acquired the equipment 
prior to September 11, 2001.

    (5) Placed-in-service date--(i) In general. Depreciable property 
will meet the requirements of this paragraph (b)(5) if the property is 
placed in service by the taxpayer before January 1, 2005, or, in the 
case of property described in section 168(k)(2)(B), is placed in service 
by the taxpayer before January 1, 2006.
    (ii) Sale-leaseback and syndication transactions--(A) Sale-leaseback 
transaction. If qualified property is originally placed in service after 
September 10, 2001, or 50-percent bonus depreciation property is 
originally placed in service after May 5, 2003, by a person and sold to 
a taxpayer and leased back to the person by the taxpayer within three 
months after the date the property was originally placed in service by 
the person, the property is treated as originally placed in service by 
the taxpayer-lessor not earlier than the date on which the property is 
used by the lessee under the leaseback.
    (B) Syndication transaction. If qualified property is originally 
placed in service after September 10, 2001, or 50-percent bonus 
depreciation property is originally placed in service after May 5, 2003, 
by a lessor (including by operation of paragraph (b)(5)(ii)(A) of this 
section) and is sold by the lessor or any subsequent purchaser within 
three months after the date the property was originally placed in 
service by the lessor, and the user of the property after the last sale 
during this three-month period remains the same as when the property was 
originally placed in service by the lessor, the property is treated as 
originally placed in service by the purchaser of the property in the 
last sale during the three-month period but not earlier than the date of 
the last sale.
    (C) Sale-leaseback transaction followed by a syndication 
transaction. If a sale-leaseback transaction that satisfies the 
requirements in paragraph (b)(5)(ii)(A) of this section is followed by a 
syndication transaction that satisfies the requirements in paragraph 
(b)(5)(ii)(B) of this section, the placed-in-service date of the 
property is determined in accordance with paragraph (b)(5)(ii)(B) of 
this section.
    (iii) Technical termination of a partnership. For purposes of this 
paragraph (b)(5), in the case of a technical termination of a 
partnership under section 708(b)(1)(B), qualified property or 50-percent 
bonus depreciation property placed in service by the terminated 
partnership during the taxable year of termination is treated as 
originally placed in service by the new partnership on the date the 
qualified property or the 50-percent bonus depreciation property is 
contributed by the terminated partnership to the new partnership.
    (iv) Section 168(i)(7) transactions. For purposes of this paragraph 
(b)(5), if qualified property or 50-percent bonus depreciation property 
is transferred in a transaction described in section 168(i)(7) in the 
same taxable year that the qualified property or the 50-percent bonus 
depreciation property is placed in service by the transferor, the 
transferred property is treated as originally placed in service on the 
date the transferor placed in service the qualified property or the 50-
percent bonus depreciation property, as applicable. In the case of 
multiple transfers of qualified property or 50-percent bonus 
depreciation property in multiple transactions described in section 
168(i)(7) in the same taxable year, the placed in service date of the 
transferred property is deemed to be the date on which the first 
transferor placed in service the

[[Page 1093]]

qualified property or the 50-percent bonus depreciation property, as 
applicable.
    (c) Qualified leasehold improvement property--(1) In general. For 
purposes of section 168(k), qualified leasehold improvement property 
means any improvement, which is section 1250 property, to an interior 
portion of a building that is nonresidential real property if--
    (i) The improvement is made under or pursuant to a lease by the 
lessee (or any sublessee) of the interior portion, or by the lessor of 
that interior portion;
    (ii) The interior portion of the building is to be occupied 
exclusively by the lessee (or any sublessee) of that interior portion; 
and
    (iii) The improvement is placed in service more than 3 years after 
the date the building was first placed in service by any person.
    (2) Certain improvements not included. Qualified leasehold 
improvement property does not include any improvement for which the 
expenditure is attributable to:
    (i) The enlargement of the building;
    (ii) Any elevator or escalator;
    (iii) Any structural component benefiting a common area; or
    (iv) The internal structural framework of the building.
    (3) Definitions. For purposes of this paragraph (c), the following 
definitions apply:
    (i) Building has the same meaning as that term is defined in Sec. 
1.48-1(e)(1).
    (ii) Common area means any portion of a building that is equally 
available to all users of the building on the same basis for uses that 
are incidental to the primary use of the building. For example, 
stairways, hallways, lobbies, common seating areas, interior and 
exterior pedestrian walkways and pedestrian bridges, loading docks and 
areas, and rest rooms generally are treated as common areas if they are 
used by different lessees of a building.
    (iii) Elevator and escalator have the same meanings as those terms 
are defined in Sec. 1.48-1(m)(2).
    (iv) Enlargement has the same meaning as that term is defined in 
Sec. 1.48-12(c)(10).
    (v) Internal structural framework has the same meaning as that term 
is defined in Sec. 1.48-12(b)(3)(i)(D)(iii).
    (vi) Lease has the same meaning as that term is defined in section 
168(h)(7). In addition, a commitment to enter into a lease is treated as 
a lease, and the parties to the commitment are treated as lessor and 
lessee. However, a lease between related persons is not considered a 
lease. For purposes of the preceding sentence, related persons are--
    (A) Members of an affiliated group (as defined in section 1504 and 
the regulations thereunder); and
    (B) Persons having a relationship described in section 267(b) and 
the regulations thereunder. For purposes of applying section 267(b), the 
language ``80 percent or more'' is used instead of ``more than 50 
percent.''
    (vii) Nonresidential real property has the same meaning as that term 
is defined in section 168(e)(2)(B).
    (viii) Structural component has the same meaning as that term is 
defined in Sec. 1.48-1(e)(2).
    (d) Computation of depreciation deduction for qualified property or 
50-percent bonus depreciation property--(1) Additional first year 
depreciation deduction--(i) In general. Except as provided in paragraph 
(f)(5) of this section, the allowable additional first year depreciation 
deduction for qualified property is determined by multiplying the 
unadjusted depreciable basis (as defined in Sec. 1.168(k)-
1T(a)(2)(iii)) of the qualified property by 30 percent. Except as 
provided in paragraph (f)(5) of this section, the allowable additional 
first year depreciation deduction for 50-percent bonus depreciation 
property is determined by multiplying the unadjusted depreciable basis 
(as defined in Sec. 1.168(k)-1T(a)(2)(iii)) of the 50-percent bonus 
depreciation property by 50 percent. Except as provided in paragraph 
(f)(1) of this section, the 30-percent or 50-percent additional first 
year depreciation deduction is not affected by a taxable year of less 
than 12 months. See paragraph (f)(1) of this section for qualified 
property or 50-percent bonus depreciation property placed in service and 
disposed of in the same taxable year. See paragraph (f)(5) of this 
section for qualified property or

[[Page 1094]]

50-percent bonus depreciation property acquired in a like-kind exchange 
or as a result of an involuntary conversion.
    (ii) Property having a longer production period. For purposes of 
paragraph (d)(1)(i) of this section, the unadjusted depreciable basis 
(as defined in Sec. 1.168(k)-1T(a)(2)(iii)) of qualified property or 
50-percent bonus depreciation property described in section 168(k)(2)(B) 
is limited to the property's unadjusted depreciable basis attributable 
to the property's manufacture, construction, or production after 
September 10, 2001 (for qualified property), or May 5, 2003 (for 50-
percent bonus depreciation property), and before January 1, 2005.
    (iii) Alternative minimum tax. The 30-percent or 50-percent 
additional first year depreciation deduction is allowed for alternative 
minimum tax purposes for the taxable year in which the qualified 
property or the 50-percent bonus depreciation property is placed in 
service by the taxpayer. The 30-percent or 50-percent additional first 
year depreciation deduction for alternative minimum tax purposes is 
based on the unadjusted depreciable basis of the property for 
alternative minimum tax purposes.
    (2) Otherwise allowable depreciation deduction. (i) In general. 
Before determining the amount otherwise allowable as a depreciation 
deduction for the qualified property or the 50-percent bonus 
depreciation property for the placed-in-service year and any subsequent 
taxable year, the taxpayer must determine the remaining adjusted 
depreciable basis of the qualified property or the 50-percent bonus 
depreciation property. This remaining adjusted depreciable basis is 
equal to the unadjusted depreciable basis of the qualified property or 
the 50-percent bonus depreciation property reduced by the amount of the 
additional first year depreciation allowed or allowable, whichever is 
greater. The remaining adjusted depreciable basis of the qualified 
property or the 50-percent bonus depreciation property is then 
depreciated using the applicable depreciation provisions under the 
Internal Revenue Code for the qualified property or the 50-percent bonus 
depreciation property. The remaining adjusted depreciable basis of the 
qualified property or the 50-percent bonus depreciation property that is 
MACRS property is also the basis to which the annual depreciation rates 
in the optional depreciation tables apply (for further guidance, see 
section 8 of Rev. Proc. 87-57 (1987-2 C.B. 687) and Sec. 
601.601(d)(2)(ii)( b) of this chapter). The depreciation deduction 
allowable for the remaining adjusted depreciable basis of the qualified 
property or the 50-percent bonus depreciation property is affected by a 
taxable year of less than 12 months.
    (ii) Alternative minimum tax. For alternative minimum tax purposes, 
the depreciation deduction allowable for the remaining adjusted 
depreciable basis of the qualified property or the 50-percent bonus 
depreciation property is based on the remaining adjusted depreciable 
basis for alternative minimum tax purposes. The remaining adjusted 
depreciable basis of the qualified property or the 50-percent bonus 
depreciable property for alternative minimum tax purposes is depreciated 
using the same depreciation method, recovery period (or useful life in 
the case of computer software), and convention that apply to the 
qualified property or the 50-percent bonus depreciation property for 
regular tax purposes.
    (3) Examples. This paragraph (d) is illustrated by the following 
examples:


    Example 1. On March 1, 2003, V, a calendar-year taxpayer, purchased 
and placed in service qualified property that costs $1 million and is 5-
year property under section 168(e). V depreciates its 5-year property 
placed in service in 2003 using the optional depreciation table that 
corresponds with the general depreciation system, the 200-percent 
declining balance method, a 5-year recovery period, and the half-year 
convention. For 2003, V is allowed a 30-percent additional first year 
depreciation deduction of $300,000 (the unadjusted depreciable basis of 
$1 million multiplied by .30). Next, V must reduce the unadjusted 
depreciable basis of $1 million by the additional first year 
depreciation deduction of $300,000 to determine the remaining adjusted 
depreciable basis of $700,000. Then, V's depreciation deduction 
allowable in 2003 for the remaining adjusted depreciable basis of 
$700,000 is $140,000 (the remaining adjusted depreciable basis of 
$700,000 multiplied by the annual depreciation rate of .20 for recovery 
year 1).



[[Page 1095]]

    Example 2. On June 1, 2003, W, a calendar-year taxpayer, purchased 
and placed in service 50-percent bonus depreciation property that costs 
$126,000. The property qualifies for the expensing election under 
section 179 and is 5-year property under section 168(e). W did not 
purchase any other section 179 property in 2003. W makes the election 
under section 179 for the property and depreciates its 5-year property 
placed in service in 2003 using the optional depreciation table that 
corresponds with the general depreciation system, the 200-percent 
declining balance method, a 5-year recovery period, and the half-year 
convention. For 2003, W is first allowed a $100,000 deduction under 
section 179. Next, W must reduce the cost of $126,000 by the section 179 
deduction of $100,000 to determine the unadjusted depreciable basis of 
$26,000. Then, for 2003, W is allowed a 50-percent additional first year 
depreciation deduction of $13,000 (the unadjusted depreciable basis of 
$26,000 multiplied by .50). Next, W must reduce the unadjusted 
depreciable basis of $26,000 by the additional first year depreciation 
deduction of $13,000 to determine the remaining adjusted depreciable 
basis of $13,000. Then, W's depreciation deduction allowable in 2003 for 
the remaining adjusted depreciable basis of $13,000 is $2,600 (the 
remaining adjusted depreciable basis of $13,000 multiplied by the annual 
depreciation rate of .20 for recovery year 1).

    (e) Election not to deduct additional first year depreciation--(1) 
In general. If a taxpayer makes an election under this paragraph (e), 
the election applies to all qualified property or 50-percent bonus 
depreciation property, as applicable, that is in the same class of 
property and placed in service in the same taxable year. The rules of 
this paragraph (e) apply to the following elections provided under 
section 168(k):
    (i) Qualified property. A taxpayer may make an election not to 
deduct the 30-percent additional first year depreciation for any class 
of property that is qualified property placed in service during the 
taxable year. If this election is made, no additional first year 
depreciation deduction is allowable for the property placed in service 
during the taxable year in the class of property.
    (ii) 50-percent bonus depreciation property. For any class of 
property that is 50-percent bonus depreciation property placed in 
service during the taxable year, a taxpayer may make an election--
    (A) To deduct the 30-percent, instead of the 50-percent, additional 
first year depreciation. If this election is made, the allowable 
additional first year depreciation deduction is determined as though the 
class of property is qualified property under section 168(k)(2); or
    (B) Not to deduct any additional first year depreciation. If this 
election is made, no additional first year depreciation deduction is 
allowable for the class of property.
    (2) Definition of class of property. For purposes of this paragraph 
(e), the term class of property means:
    (i) Except for the property described in paragraphs (e)(2)(ii) and 
(iv) of this section, each class of property described in section 168(e) 
(for example, 5-year property);
    (ii) Water utility property as defined in section 168(e)(5) and 
depreciated under section 168;
    (iii) Computer software as defined in, and depreciated under, 
section 167(f)(1) and the regulations thereunder; or
    (iv) Qualified leasehold improvement property as defined in 
paragraph (c) of this section and depreciated under section 168.
    (3) Time and manner for making election--(i) Time for making 
election. Except as provided in paragraph (e)(4) of this section, any 
election specified in paragraph (e)(1) of this section must be made by 
the due date (including extensions) of the Federal tax return for the 
taxable year in which the qualified property or the 50-percent bonus 
depreciation property, as applicable, is placed in service by the 
taxpayer.
    (ii) Manner of making election. Except as provided in paragraph 
(e)(4) of this section, any election specified in paragraph (e)(1) of 
this section must be made in the manner prescribed on Form 4562, 
``Depreciation and Amortization,'' and its instructions. The election is 
made separately by each person owning qualified property or 50-percent 
bonus depreciation property (for example, for each member of a 
consolidated group by the common parent of the group, by the 
partnership, or by the S corporation). If Form 4562 is revised or 
renumbered, any reference in this section to that form shall be treated 
as a reference to the revised or renumbered form.
    (4) Special rules for 2000 or 2001 returns. For the election 
specified in paragraph

[[Page 1096]]

(e)(1)(i) of this section for qualified property placed in service by 
the taxpayer during the taxable year that included September 11, 2001, 
the taxpayer should refer to the guidance provided by the Internal 
Revenue Service for the time and manner of making this election on the 
2000 or 2001 Federal tax return for the taxable year that included 
September 11, 2001 (for further guidance, see sections 3.03(3) and 4 of 
Rev. Proc. 2002-33 (2002-1 C.B. 963), Rev. Proc. 2003-50 (2003-29 I.R.B. 
119), and Sec. 601.601(d)(2)(ii)(b) of this chapter).
    (5) Failure to make election. If a taxpayer does not make the 
applicable election specified in paragraph (e)(1) of this section within 
the time and in the manner prescribed in paragraph (e)(3) or (4) of this 
section, the amount of depreciation allowable for that property under 
section 167(f)(1) or under section 168, as applicable, must be 
determined for the placed-in-service year and for all subsequent taxable 
years by taking into account the additional first year depreciation 
deduction. Thus, any election specified in paragraph (e)(1) of this 
section shall not be made by the taxpayer in any other manner (for 
example, the election cannot be made through a request under section 
446(e) to change the taxpayer's method of accounting).
    (f) Special rules--(1) Property placed in service and disposed of in 
the same taxable year--(i) In general. Except as provided in paragraphs 
(f)(1)(ii) and (iii) of this section, the additional first year 
depreciation deduction is not allowed for qualified property or 50-
percent bonus depreciation property placed in service and disposed of 
during the same taxable year.
    (ii) Technical termination of a partnership. In the case of a 
technical termination of a partnership under section 708(b)(1)(B), the 
additional first year depreciation deduction is allowable for any 
qualified property or 50-percent bonus depreciation property placed in 
service by the terminated partnership during the taxable year of 
termination and contributed by the terminated partnership to the new 
partnership. The allowable additional first year depreciation deduction 
for the qualified property or the 50-percent bonus depreciation property 
shall not be claimed by the terminated partnership but instead shall be 
claimed by the new partnership for the new partnership's taxable year in 
which the qualified property or the 50-percent bonus depreciation 
property was contributed by the terminated partnership to the new 
partnership. However, if qualified property or 50-percent bonus 
depreciation property is both placed in service and contributed to a new 
partnership in a transaction described in section 708(b)(1)(B) by the 
terminated partnership during the taxable year of termination, and if 
such property is disposed of by the new partnership in the same taxable 
year the new partnership received such property from the terminated 
partnership, then no additional first year depreciation deduction is 
allowable to either partnership.
    (iii) Section 168(i)(7) transactions. If any qualified property or 
50-percent bonus depreciation property is transferred in a transaction 
described in section 168(i)(7) in the same taxable year that the 
qualified property or the 50-percent bonus depreciation property is 
placed in service by the transferor, the additional first year 
depreciation deduction is allowable for the qualified property or the 
50-percent bonus depreciation property. The allowable additional first 
year depreciation deduction for the qualified property or the 50-percent 
bonus depreciation property for the transferor's taxable year in which 
the property is placed in service is allocated between the transferor 
and the transferee on a monthly basis. This allocation shall be made in 
accordance with the rules in Sec. 1.168(d)-1(b)(7)(ii) for allocating 
the depreciation deduction between the transferor and the transferee. 
However, if qualified property or 50-percent bonus depreciation property 
is both placed in service and transferred in a transaction described in 
section 168(i)(7) by the transferor during the same taxable year, and if 
such property is disposed of by the transferee (other than by a 
transaction described in section 168(i)(7)) during the same taxable year 
the transferee received such property from the transferor, then no 
additional first year depreciation deduction is allowable to either 
party.

[[Page 1097]]

    (iv) Examples. The application of this paragraph (f)(1) is 
illustrated by the following examples:

    Example 1. X and Y are equal partners in Partnership XY, a general 
partnership. On February 1, 2002, Partnership XY purchased and placed in 
service new equipment at a cost of $30,000. On March 1, 2002, X sells 
its entire 50 percent interest to Z in a transfer that terminates the 
partnership under section 708(b)(1)(B). As a result, terminated 
Partnership XY is deemed to have contributed the equipment to new 
Partnership XY. Pursuant to paragraph (f)(1)(ii) of this section, new 
Partnership XY, not terminated Partnership XY, is eligible to claim the 
30-percent additional first year depreciation deduction allowable for 
the equipment for the taxable year 2002 (assuming all other requirements 
are met).
    Example 2. On January 5, 2002, BB purchased and placed in service 
new office desks for a total amount of $8,000. On August 20, 2002, BB 
transferred the office desks to Partnership BC in a transaction 
described in section 721. BB and Partnership BC are calendar-year 
taxpayers. Because the transaction between BB and Partnership BC is a 
transaction described in section 168(i)(7), pursuant to paragraph 
(f)(1)(iii) of this section the 30-percent additional first year 
depreciation deduction allowable for the desks is allocated between BB 
and Partnership BC in accordance with the rules in Sec. 1.168(d)-
1(b)(7)(ii) for allocating the depreciation deduction between the 
transferor and the transferee. Accordingly, the 30-percent additional 
first year depreciation deduction allowable for the desks for 2002 of 
$2,400 (the unadjusted depreciable basis of $8,000 multiplied by .30) is 
allocated between BB and Partnership BC based on the number of months 
that BB and Partnership BC held the desks in service. Thus, because the 
desks were held in service by BB for 7 of 12 months, which includes the 
month in which BB placed the desks in service but does not include the 
month in which the desks were transferred, BB is allocated $1,400 (\7/
12\ x $2,400 additional first year depreciation deduction). Partnership 
BC is allocated $1,000, the remaining \5/12\ of the $2,400 additional 
first year depreciation deduction allowable for the desks.

    (2) Redetermination of basis. If the unadjusted depreciable basis 
(as defined in Sec. 1.168(k)-1T(a)(2)(iii)) of qualified property or 
50-percent bonus depreciation property is redetermined (for example, due 
to contingent purchase price or discharge of indebtedness) by January 1, 
2005 (or January 1, 2006, for property described in section 
168(k)(2)(B)), the additional first year depreciation deduction 
allowable for the qualified property or the 50-percent bonus 
depreciation property is redetermined as follows:
    (i) Increase in basis. For the taxable year in which an increase in 
basis of qualified property or 50-percent bonus depreciation property 
occurs, the taxpayer shall claim an additional first year depreciation 
deduction for qualified property by multiplying the amount of the 
increase in basis for this property by 30 percent or, for 50-percent 
bonus depreciation property, by multiplying the amount of the increase 
in basis for this property by 50 percent. For purposes of this paragraph 
(f)(2)(i), the 30-percent additional first year depreciation deduction 
applies to the increase in basis if the underlying property is qualified 
property and the 50-percent additional first year depreciation deduction 
applies to the increase in basis if the underlying property is 50-
percent bonus depreciation property. To determine the amount otherwise 
allowable as a depreciation deduction for the increase in basis of 
qualified property or 50-percent bonus depreciation property, the amount 
of the increase in basis of the qualified property or the 50-percent 
bonus depreciation property must be reduced by the additional first year 
depreciation deduction allowed or allowable, whichever is greater, for 
the increase in basis and the remaining increase in basis of--
    (A) Qualified property or 50-percent bonus depreciation property 
(except for computer software described in paragraph (b)(2)(i)(B) of 
this section) is depreciated over the recovery period of the qualified 
property or the 50-percent bonus depreciation property, as applicable, 
remaining as of the beginning of the taxable year in which the increase 
in basis occurs, and using the same depreciation method and convention 
applicable to the qualified property or 50-percent bonus depreciation 
property, as applicable, that applies for the taxable year in which the 
increase in basis occurs; and
    (B) Computer software (as defined in paragraph (b)(2)(i)(B) of this 
section) that is qualified property or 50-percent bonus depreciation 
property is depreciated ratably over the remainder of the 36-month 
period (the useful life

[[Page 1098]]

under section 167(f)(1)) as of the beginning of the first day of the 
month in which the increase in basis occurs.
    (ii) Decrease in basis. For the taxable year in which a decrease in 
basis of qualified property or 50-percent bonus depreciation property 
occurs, the taxpayer shall include in the taxpayer's income the excess 
additional first year depreciation deduction previously claimed for the 
qualified property or the 50-percent bonus depreciation property. This 
excess additional first year depreciation deduction for qualified 
property is determined by multiplying the amount of the decrease in 
basis for this property by 30 percent. The excess additional first year 
depreciation deduction for 50-percent bonus depreciation property is 
determined by multiplying the amount of the decrease in basis for this 
property by 50 percent. For purposes of this paragraph (f)(2)(ii), the 
30-percent additional first year depreciation deduction applies to the 
decrease in basis if the underlying property is qualified property and 
the 50-percent additional first year depreciation deduction applies to 
the decrease in basis if the underlying property is 50-percent bonus 
depreciation property. Also, if the taxpayer establishes by adequate 
records or other sufficient evidence that the taxpayer claimed less than 
the additional first year depreciation deduction allowable for the 
qualified property or the 50-percent bonus depreciation property before 
the decrease in basis or if the taxpayer claimed more than the 
additional first year depreciation deduction allowable for the qualified 
property or the 50-percent bonus depreciation property before the 
decrease in basis, the excess additional first year depreciation 
deduction is determined by multiplying the amount of the decrease in 
basis by the additional first year depreciation deduction percentage 
actually claimed by the taxpayer for the qualified property or the 50-
percent bonus depreciation property, as applicable, before the decrease 
in basis. To determine the amount includible in the taxpayer's income 
for the excess depreciation previously claimed (other than the 
additional first year depreciation deduction) resulting from the 
decrease in basis of the qualified property or the 50-percent bonus 
depreciation property, the amount of the decrease in basis of the 
qualified property or the 50-percent bonus depreciation property must be 
adjusted by the excess additional first year depreciation deduction 
includible in the taxpayer's income (as determined under this paragraph) 
and the remaining decrease in basis of--
    (A) Qualified property or 50-percent bonus depreciation property 
(except for computer software described in paragraph (b)(2)(i)(B) of 
this section) is included in the taxpayer's income over the recovery 
period of the qualified property or the 50-percent bonus depreciation 
property, as applicable, remaining as of the beginning of the taxable 
year in which the decrease in basis occurs, and using the same 
depreciation method and convention of the qualified property or 50-
percent bonus depreciation property, as applicable, that applies in the 
taxable year in which the decrease in basis occurs; and
    (B) Computer software (as defined in paragraph (b)(2)(i)(B) of this 
section) that is qualified property or 50-percent bonus depreciation 
property is included in the taxpayer's income ratably over the remainder 
of the 36-month period (the useful life under section 167(f)(1)) as of 
the beginning of the first day of the month in which the decrease in 
basis occurs.
    (iii) Definition. For purposes of this paragraph (f)(2)--
    (A) An increase in basis occurs in the taxable year an amount is 
taken into account under section 461; and
    (B) A decrease in basis occurs in the taxable year an amount would 
be taken into account under section 451.
    (iv) Examples. The application of this paragraph (f)(2) is 
illustrated by the following examples:

    Example 1. (i) On May 15, 2002, CC, a cash-basis taxpayer, purchased 
and placed in service qualified property that is 5-year property at a 
cost of $200,000. In addition to the $200,000, CC agrees to pay the 
seller 25 percent of the gross profits from the operation of the 
property in 2002. On May 15, 2003, CC paid to the seller an additional 
$10,000. CC depreciates the 5-year property placed in service in 2002 
using the optional depreciation table that corresponds with the general 
depreciation system, the 200-percent declining balance method, a 5-year 
recovery period, and the half-year convention.

[[Page 1099]]

    (ii) For 2002, CC is allowed a 30-percent additional first year 
depreciation deduction of $60,000 (the unadjusted depreciable basis of 
$200,000 multiplied by .30). In addition, CC's depreciation deduction 
for 2002 for the remaining adjusted depreciable basis of $140,000 (the 
unadjusted depreciable basis of $200,000 reduced by the additional first 
year depreciation deduction of $60,000) is $28,000 (the remaining 
adjusted depreciable basis of $140,000 multiplied by the annual 
depreciation rate of .20 for recovery year 1).
    (iii) For 2003, CC's depreciation deduction for the remaining 
adjusted depreciable basis of $140,000 is $44,800 (the remaining 
adjusted depreciable basis of $140,000 multiplied by the annual 
depreciation rate of .32 for recovery year 2). In addition, pursuant to 
paragraph (f)(2)(i) of this section, CC is allowed an additional first 
year depreciation deduction for 2003 for the $10,000 increase in basis 
of the qualified property. Consequently, CC is allowed an additional 
first year depreciation deduction of $3,000 (the increase in basis of 
$10,000 multiplied by .30). Also, CC is allowed a depreciation deduction 
for 2003 attributable to the remaining increase in basis of $7,000 (the 
increase in basis of $10,000 reduced by the additional first year 
depreciation deduction of $3,000). The depreciation deduction allowable 
for 2003 attributable to the remaining increase in basis of $7,000 is 
$3,111 (the remaining increase in basis of $7,000 multiplied by .4444, 
which is equal to 1/remaining recovery period of 4.5 years at January 1, 
2003, multiplied by 2). Accordingly, for 2003, CC's total depreciation 
deduction allowable for the qualified property is $50,911.
    Example 2. (i) On May 15, 2002, CC purchased and placed in service 
qualified property that is 5-year property at a cost of $400,000. To 
purchase the property, DD borrowed $250,000 from Bank2. On May 15, 2003, 
Bank2 forgives $50,000 of the indebtedness. DD makes the election 
provided in section 108(b)(5) to apply any portion of the reduction 
under section 1017 to the basis of the depreciable property of the 
taxpayer. DD depreciates the 5-year property placed in service in 2002 
using the optional depreciation table that corresponds with the general 
depreciation system, the 200-percent declining balance method, a 5-year 
recovery period, and the half-year convention.
    (ii) For 2002, DD is allowed a 30-percent additional first year 
depreciation deduction of $120,000 (the unadjusted depreciable basis of 
$400,000 multiplied by .30). In addition, DD's depreciation deduction 
allowable for 2002 for the remaining adjusted depreciable basis of 
$280,000 (the unadjusted depreciable basis of $400,000 reduced by the 
additional first year depreciation deduction of $120,000) is $56,000 
(the remaining adjusted depreciable basis of $280,000 multiplied by the 
annual depreciation rate of .20 for recovery year 1).
    (iii) For 2003, DD's deduction for the remaining adjusted 
depreciable basis of $280,000 is $89,600 (the remaining adjusted 
depreciable basis of $280,000 multiplied by the annual depreciation rate 
of .32 for recovery year 2). However, pursuant to paragraph (f)(2)(ii) 
of this section, DD must include in its taxable income for 2003 the 
excess depreciation previously claimed for the $50,000 decrease in basis 
of the qualified property. Consequently, DD must include in its taxable 
income for 2003 the excess additional first year depreciation of $4,500 
(the decrease in basis of $50,000 multiplied by .30). Also, DD must 
include in its taxable income for 2003 the excess depreciation 
attributable to the remaining decrease in basis of $45,500 (the decrease 
in basis of $50,000 reduced by the excess additional first year 
depreciation of $4,500). The amount includible in taxable income for 
2003 for the remaining decrease in basis of $45,500 is $20,222 (the 
remaining decrease in basis of $45,500 multiplied by .4444, which is 
equal to 1/remaining recovery period of 4.5 years at January 1, 2003, 
multiplied by 2). Accordingly, for 2003, DD's total depreciation 
deduction allowable for the qualified property is $64,878 ($89,600 minus 
$4,500 minus $20,222).

    (3) Section 1245 and 1250 depreciation recapture. For purposes of 
section 1245 and the regulations thereunder, the additional first year 
depreciation deduction is an amount allowed or allowable for 
depreciation. Further, for purposes of section 1250(b) and the 
regulations thereunder, the additional first year depreciation deduction 
is not a straight line method.
    (4) Coordination with section 169. The additional first year 
depreciation deduction is allowable in the placed-in-service year of a 
certified pollution control facility (as defined in Sec. 1.169-2(a)) 
that is qualified property or 50-percent bonus depreciation property, 
even if the taxpayer makes the election to amortize the certified 
pollution control facility under section 169 and the regulations 
thereunder in the certified pollution control facility's placed-in-
service year.
    (5) Like-kind exchanges and involuntary conversions--(i) Scope. The 
rules of this paragraph (f)(5) apply to acquired MACRS property or 
acquired computer software that is eligible for the additional first 
year depreciation deduction under section 168(k) at the time of 
replacement provided the time of replacement is after September 10, 
2001, and before January 1, 2005, or, in the case of acquired MACRS 
property or

[[Page 1100]]

acquired computer software that is qualified property, or 50-percent 
bonus depreciation property, described in section 168(k)(2)(B), the time 
of replacement is after September 10, 2001, and before January 1, 2006.
    (ii) Definitions. For purposes of this paragraph (f)(5), the 
following definitions apply:
    (A) Acquired MACRS property is MACRS property in the hands of the 
acquiring taxpayer that is acquired in a transaction described in 
section 1031(a), (b), or (c) for other MACRS property or that is 
acquired in connection with an involuntary conversion of other MACRS 
property in a transaction to which section 1033 applies.
    (B) Exchanged or involuntarily converted MACRS property is MACRS 
property that is transferred by the taxpayer in a transaction described 
in section 1031(a), (b), or (c), or that is converted as a result of an 
involuntary conversion to which section 1033 applies.
    (C) Acquired computer software is computer software (as defined in 
paragraph (b)(2)(i)(B) of this section) in the hands of the acquiring 
taxpayer that is acquired in a like-kind exchange under section 1031 or 
as a result of an involuntary conversion under section 1033.
    (D) Exchanged or involuntarily converted computer software is 
computer software (as defined in paragraph (b)(2)(i)(B) of this section) 
that is transferred by the taxpayer in a like-kind exchange under 
section 1031 or that is converted as a result of an involuntary 
conversion under section 1033.
    (E) Time of disposition is when the disposition of the exchanged or 
involuntarily converted MACRS property or the exchanged or involuntarily 
converted computer software, as applicable, takes place.
    (F) Time of replacement is the later of:
    (1) When the property received in the exchange or involuntary 
conversion is placed in service; or
    (2) The time of disposition of the exchanged or involuntarily 
converted property.
    (G) Carryover basis is the lesser of:
    (1) The basis in the acquired MACRS property or acquired computer 
software, as applicable and as determined under section 1031(d) or 
1033(b) and the regulations thereunder; or
    (2) The adjusted depreciable basis of the exchanged or involuntarily 
converted MACRS property or the exchanged or involuntarily converted 
computer software, as applicable.
    (H) Excess basis is any excess of the basis in the acquired MACRS 
property or acquired computer software, as applicable and as determined 
under section 1031(d) or 1033(b) and the regulations thereunder, over 
the carryover basis as determined under paragraph (f)(5)(ii)(G) of this 
section.
    (I) Remaining carryover basis is the carryover basis as determined 
under paragraph (f)(5)(ii)(G) of this section reduced by--
    (1) The percentage of the taxpayer's use of property for the taxable 
year other than in the taxpayer's trade or business (or for the 
production of income); and
    (2) Any adjustments to basis provided by other provisions of the 
Code and the regulations thereunder (including section 1016(a)(2) and 
(3)) for periods prior to the disposition of the exchanged or 
involuntarily converted property.
    (J) Remaining excess basis is the excess basis as determined under 
paragraph (f)(5)(ii)(H) of this section reduced by--
    (1) The percentage of the taxpayer's use of property for the taxable 
year other than in the taxpayer's trade or business (or for the 
production of income);
    (2) Any portion of the basis the taxpayer properly elects to treat 
as an expense under section 179; and
    (3) Any adjustments to basis provided by other provisions of the 
Code and the regulations thereunder.
    (iii) Computation--(A) In general. Assuming all other requirements 
are met, the remaining carryover basis for the year of replacement and 
the remaining excess basis, if any, for the year of replacement for the 
acquired MACRS property or the acquired computer software, as 
applicable, are eligible for the additional first year depreciation 
deduction. The 30-percent additional first year depreciation deduction 
applies to the remaining carryover basis and the remaining excess basis, 
if any, of the acquired MACRS property or the

[[Page 1101]]

acquired computer software if the time of replacement is after September 
10, 2001, and before May 6, 2003, or if the taxpayer made the election 
provided in paragraph (e)(1)(ii)(A) of this section. The 50-percent 
additional first year depreciation deduction applies to the remaining 
carryover basis and the remaining excess basis, if any, of the acquired 
MACRS property or the acquired computer software if the time of 
replacement is after May 5, 2003, and before January 1, 2005, or before 
January 1, 2006, for 50-percent bonus depreciation property described in 
section 168(k)(2)(B). The additional first year depreciation deduction 
is computed separately for the remaining carryover basis and the 
remaining excess basis. Rules similar to the rules provided in paragraph 
(d) of this section apply to property described in section 168(k)(2)(B) 
and for alternative minimum tax purposes (for example, use the remaining 
carryover basis as determined for alternative minimum tax purposes).
    (B) Year of disposition and year of replacement. The additional 
first year depreciation deduction is allowable for the acquired MACRS 
property or acquired computer software in the year of replacement. 
However, the additional first year depreciation deduction is not 
allowable for the exchanged or involuntarily converted MACRS property or 
the exchanged or involuntarily converted computer software if the MACRS 
property or computer software, as applicable, is placed in service and 
disposed of in an exchange or involuntary conversion in the same taxable 
year.
    (iv) Sale-leaseback transaction. For purposes of this paragraph 
(f)(5), if MACRS property or computer software is sold to a taxpayer and 
leased back to a person by the taxpayer within three months after the 
time of disposition of the MACRS property or computer software, as 
applicable, the time of replacement for this MACRS property or computer 
software, as applicable, shall not be earlier than the date on which the 
MACRS property or computer software, as applicable, is used by the 
lessee under the leaseback.
    (v) Examples. The application of this paragraph (f)(5) is 
illustrated by the following examples:
    Example 1. (i) In December 2002, EE, a calendar-year corporation, 
acquired for $200,000 and placed in service Canopy V1, a gas station 
canopy. Canopy V1 is qualified property under section 168(k)(1) and is 
5-year property under section 168(e). EE depreciated Canopy V1 under the 
general depreciation system of section 168(a) by using the 200-percent 
declining balance method of depreciation, a 5-year recovery period, and 
the half-year convention. EE elected to use the optional depreciation 
tables to compute the depreciation allowance for Canopy V1. On January 
1, 2003, Canopy V1 was destroyed in a fire and was no longer usable in 
EE's business. On June 1, 2003, in an involuntary conversion, EE 
acquired and placed in service Canopy W1 with all of the $160,000 of 
insurance proceeds EE received due to the loss of Canopy V1. Canopy W1 
is 50-percent bonus depreciation property under section 168(k)(4) and is 
5-year property under section 168(e). Pursuant to paragraph (g)(3)(ii) 
of this section and Sec. 1.168(i)-6T(k)(2)(i), EE decided to apply 
Sec. 1.168(i)-6T to the involuntary conversion of Canopy V1 with the 
replacement of Canopy W1, the acquired MACRS property.
    (ii) For 2002, EE is allowed a 30-percent additional first year 
depreciation deduction of $60,000 for Canopy V1 (the unadjusted 
depreciable basis of $200,000 multiplied by .30), and a regular MACRS 
depreciation deduction of $28,000 for Canopy V1 (the remaining adjusted 
depreciable basis of $140,000 multiplied by the annual depreciation rate 
of .20 for recovery year 1).
    (iii) For 2003, EE is allowed a regular MACRS depreciation deduction 
of $22,400 for Canopy V1 (the remaining adjusted depreciable basis of 
$140,000 multiplied by the annual depreciation rate of .32 for recovery 
year 2 x \1/2\ year).
    (iv) Pursuant to paragraph (f)(5)(iii)(A) of this section, the 
additional first year depreciation deduction allowable for Canopy W1 
equals $44,800 (.50 of Canopy W1's remaining carryover basis at the time 
of replacement of $89,600 (Canopy V1's remaining adjusted depreciable 
basis of $140,000 minus 2002 regular MACRS depreciation deduction of 
$28,000 minus 2003 regular MACRS depreciation deduction of $22,400)).
    Example 2. (i) Same facts as in Example 1, except EE elected not to 
deduct the additional first year depreciation for 5-year property placed 
in service in 2002. EE deducted the additional first year depreciation 
for 5-year property placed in service in 2003.
    (ii) For 2002, EE is allowed a regular MACRS depreciation deduction 
of $40,000 for Canopy V1 (the unadjusted depreciable basis of $200,000 
multiplied by the annual depreciation rate of .20 for recovery year 1).

[[Page 1102]]

    (iii) For 2003, EE is allowed a regular MACRS depreciation deduction 
of $32,000 for Canopy V1 (the unadjusted depreciable basis of $200,000 
multiplied by the annual depreciation rate of .32 for recovery year 2 x 
\1/2\ year).
    (iv) Pursuant to paragraph (f)(5)(iii)(A) of this section, the 
additional first year depreciation deduction allowable for Canopy W1 
equals $64,000 (.50 of Canopy W1's remaining carryover basis at the time 
of replacement of $128,000 (Canopy V1's unadjusted depreciable basis of 
$200,000 minus 2002 regular MACRS depreciation deduction of $40,000 
minus 2003 regular MACRS depreciation deduction of $32,000)).
    Example 3. (i) In December 2001, FF, a calendar-year corporation, 
acquired for $10,000 and placed in service Computer X2. Computer X2 is 
qualified property under section 168(k)(1) and is 5-year property under 
section 168(e). FF depreciated Computer X2 under the general 
depreciation system of section 168(a) by using the 200-percent declining 
balance method of depreciation, a 5-year recovery period, and the half-
year convention. FF elected to use the optional depreciation tables to 
compute the depreciation allowance for Computer X2. On January 1, 2002, 
FF acquired Computer Y2 by exchanging Computer X2 and $1,000 cash in a 
like-kind exchange. Computer Y2 is qualified property under section 
168(k)(1) and is 5-year property under section 168(e). Pursuant to 
paragraph (g)(3)(ii) of this section and Sec. 1.168(i)-6T(k)(2)(i), FF 
decided to apply Sec. 1.168(i)-6T to the exchange of Computer X2 for 
Computer Y2, the acquired MACRS property.
    (ii) For 2001, FF is allowed a 30-percent additional first year 
depreciation deduction of $3,000 for Computer X2 (unadjusted basis of 
$10,000 multiplied by .30), and a regular MACRS depreciation deduction 
of $1,400 for Computer X2 (the remaining adjusted depreciable basis of 
$7,000 multiplied by the annual depreciation rate of .20 for recovery 
year 1).
    (iii) For 2002, FF is allowed a regular MACRS depreciation deduction 
of $1,120 for Computer X2 (the remaining adjusted depreciable basis of 
$7,000 multiplied by the annual depreciation rate of .32 for recovery 
year 2 x \1/2\ year).
    (iv) Pursuant to paragraph (f)(5)(iii)(A) of this section, the 30-
percent additional first year depreciation deduction for Computer Y2 is 
allowable for the remaining carryover basis at the time of replacement 
of $4,480 (Computer X2's unadjusted depreciable basis of $10,000 minus 
additional first year depreciation deduction allowable of $3,000 minus 
2001 regular MACRS depreciation deduction of $1,400 minus 2002 regular 
MACRS depreciation deduction of $1,120) and for the remaining excess 
basis at the time of replacement of $1,000 (cash paid for Computer Y2). 
Thus, the 30-percent additional first year depreciation deduction for 
the remaining carryover basis at the time of replacement equals $1,344 
($4,480 multiplied by .30) and for the remaining excess basis at the 
time of replacement equals $300 ($1,000 multiplied by .30), which totals 
$1,644.
    Example 4. (i) In September 2002, GG, a June 30 year-end 
corporation, acquired for $20,000 and placed in service Equipment X3. 
Equipment X3 is qualified property under section 168(k)(1) and is 5-year 
property under section 168(e). GG depreciated Equipment X3 under the 
general depreciation system of section 168(a) by using the 200-percent 
declining balance method of depreciation, a 5-year recovery period, and 
the half-year convention. GG elected to use the optional depreciation 
tables to compute the depreciation allowance for Equipment X3. In 
December 2002, GG acquired Equipment Y3 by exchanging Equipment X3 and 
$5,000 cash in a like-kind exchange. Equipment Y3 is qualified property 
under section 168(k)(1) and is 5-year property under section 168(e). 
Pursuant to paragraph (g)(3)(ii) of this section and Sec. 1.168(i)-
6T(k)(2)(i), GG decided to apply Sec. 1.168(i)-6T to the exchange of 
Equipment X3 for Equipment Y3, the acquired MACRS property.
    (ii) Pursuant to paragraph (f)(5)(iii)(B) of this section, no 
additional first year depreciation deduction is allowable for Equipment 
X3 and, pursuant to Sec. 1.168(d)-1T(b)(3)(ii), no regular depreciation 
deduction is allowable for Equipment X3, for the taxable year ended June 
30, 2003.
    (iii) Pursuant to paragraph (f)(5)(iii)(A) of this section, the 30-
percent additional first year depreciation deduction for Equipment Y3 is 
allowable for the remaining carryover basis at the time of replacement 
of $20,000 (Equipment X3's unadjusted depreciable basis of $20,000) and 
for the remaining excess basis at the time of replacement of $5,000 
(cash paid for Equipment Y3). Thus, the 30-percent additional first year 
depreciation deduction for the remaining carryover basis at the time of 
replacement equals $6,000 ($20,000 multiplied by .30) and for the 
remaining excess basis at the time of replacement equals $1,500 ($5,000 
multiplied by .30), which totals $7,500.
    Example 5. (i) Same facts as in Example 4. GG depreciated Equipment 
Y3 under the general depreciation system of section 168(a) by using the 
200-percent declining balance method of depreciation, a 5-year recovery 
period, and the half-year convention. GG elected to use the optional 
depreciation tables to compute the depreciation allowance for Equipment 
Y3. On July 1, 2003, GG acquired Equipment Z1 by exchanging Equipment Y3 
in a like-kind exchange. Equipment Z1 is 50-percent bonus depreciation 
property under section 168(k)(4) and is 5-year property under section 
168(e). Pursuant to paragraph (g)(3)(ii) of this section and Sec. 
1.168(i)-6T(k)(2)(i), GG decided to apply Sec. 1.168(i)-6T

[[Page 1103]]

to the exchange of Equipment Y3 for Equipment Z3, the acquired MACRS 
property.
    (ii) For the taxable year ending June 30, 2003, the regular MACRS 
depreciation deduction allowable for the remaining carryover basis at 
the time of replacement (after taking into account the additional first 
year depreciation deduction) of Equipment Y3 is $2,800 (the remaining 
carryover basis at the time of replacement of $20,000 minus the 
additional first year depreciation deduction of $6,000, multiplied by 
the annual depreciation rate of .20 for recovery year 1) and for the 
remaining excess basis at the time of replacement (after taking into 
account the additional first year depreciation deduction) of Equipment 
Y3 is $700 (the remaining excess basis at the time of replacement of 
$5,000 minus the additional first year depreciation deduction of $1,500, 
multiplied by the annual depreciation rate of .20 for recovery year 1), 
which totals $3,500.
    (iii) For the taxable year ending June 30, 2004, the regular MACRS 
depreciation deduction allowable for the remaining carryover basis 
(after taking into account the additional first year depreciation 
deduction) of Equipment Y3 is $2,240 (the remaining carryover basis at 
the time of replacement of $20,000 minus the additional first year 
depreciation deduction of $6,000, multiplied by the annual depreciation 
rate of .32 for recovery year 2 x \1/2\ year) and for the remaining 
excess basis (after taking into account the additional first year 
depreciation deduction) of Equipment Y3 is $560 (the remaining excess 
basis at the time of replacement of $5,000 minus the additional first 
year depreciation deduction of $1,500, multiplied by the annual 
depreciation rate of .32 for recovery year 2 x \1/2\ year), which totals 
$2,800.
    (iv) For the taxable year ending June 30, 2004, pursuant to 
paragraph (f)(5)(iii)(A) of this section, the 50-percent additional 
first year depreciation deduction for Equipment Z1 is allowable for the 
remaining carryover basis at the time of replacement of $11,200 
(Equipment Y3's unadjusted depreciable basis of $25,000 minus the total 
additional first year depreciation deduction of $7,500 minus the total 
2003 regular MACRS depreciation deduction of $3,500 minus the total 2004 
regular depreciation deduction (taking into account the half-year 
convention) of $2,800). Thus, the 50-percent additional first year 
depreciation deduction for the remaining carryover basis at the time of 
replacement equals $5,600 ($11,200 multiplied by .50).

    (6) Change in use--(i) Change in use of depreciable property. The 
determination of whether the use of depreciable property changes is made 
in accordance with section 168(i)(5) and regulations thereunder.
    (ii) Conversion to personal use. If qualified property or 50-percent 
bonus depreciation property is converted from business or income-
producing use to personal use in the same taxable year in which the 
property is placed in service by a taxpayer, the additional first year 
depreciation deduction is not allowable for the property.
    (iii) Conversion to business or income-producing use--(A) During the 
same taxable year. If, during the same taxable year, property is 
acquired by a taxpayer for personal use and is converted by the taxpayer 
from personal use to business or income-producing use, the additional 
first year depreciation deduction is allowable for the property in the 
taxable year the property is converted to business or income-producing 
use (assuming all of the requirements in paragraph (b) of this section 
are met). See paragraph (b)(3)(ii) of this section relating to the 
original use rules for a conversion of property to business or income-
producing use.
    (B) Subsequent to the acquisition year. If property is acquired by a 
taxpayer for personal use and, during a subsequent taxable year, is 
converted by the taxpayer from personal use to business or income-
producing use, the additional first year depreciation deduction is 
allowable for the property in the taxable year the property is converted 
to business or income-producing use (assuming all of the requirements in 
paragraph (b) of this section are met). For purposes of paragraphs 
(b)(4) and (5) of this section, the property must be acquired by the 
taxpayer for personal use after September 10, 2001 (for qualified 
property), or after May 5, 2003 (for 50-percent bonus depreciation 
property), and converted by the taxpayer from personal use to business 
or income-producing use by January 1, 2005. See paragraph (b)(3)(ii) of 
this section relating to the original use rules for a conversion of 
property to business or income-producing use.
    (iv) Depreciable property changes use subsequent to the placed-in-
service year--(A) If the use of qualified property or 50-percent bonus 
depreciation property changes in the hands of the same taxpayer 
subsequent to the taxable year the qualified property or the 50-percent

[[Page 1104]]

bonus depreciation property, as applicable, is placed in service and, as 
a result of the change in use, the property is no longer qualified 
property or 50-percent bonus depreciation property, as applicable, the 
additional first year depreciation deduction allowable for the qualified 
property or the 50-percent bonus depreciation property, as applicable, 
is not redetermined.
    (B) If depreciable property is not qualified property or 50-percent 
bonus depreciation property in the taxable year the property is placed 
in service by the taxpayer, the additional first year depreciation 
deduction is not allowable for the property even if a change in the use 
of the property subsequent to the taxable year the property is placed in 
service results in the property being qualified property or 50-percent 
bonus depreciation property in the taxable year of the change in use.
    (v) Examples. The application of this paragraph (f)(6) is 
illustrated by the following examples:
    Example 1. (i) On January 1, 2002, HH, a calendar year corporation, 
purchased and placed in service several new computers at a total cost of 
$100,000. HH used these computers within the United States for 3 months 
in 2002 and then moved and used the computers outside the United States 
for the remainder of 2002. On January 1, 2003, HH permanently returns 
the computers to the United States for use in its business.
    (ii) For 2002, the computers are considered as used predominantly 
outside the United States in 2002 pursuant to Sec. 1.48-1(g)(1)(i). As 
a result, the computers are required to be depreciated under the 
alternative depreciation system of section 168(g). Pursuant to paragraph 
(b)(2)(ii)(A)2) of this section, the computers are not qualified 
property in 2002, the placed-in-service year. Thus, pursuant to 
(f)(6)(iv)(B) of this section, no additional first year depreciation 
deduction is allowed for these computers, regardless of the fact that 
the computers are permanently returned to the United States in 2003.
    Example 2. (i) On February 8, 2002, II, a calendar year corporation, 
purchased and placed in service new equipment at a cost of $1,000,000 
for use in its California plant. The equipment is 5-year property under 
section 168(e) and is qualified property under section 168(k). II 
depreciates its 5-year property placed in service in 2002 using the 
optional depreciation table that corresponds with the general 
depreciation system, the 200-percent declining balance method, a 5-year 
recovery period, and the half-year convention. On June 4, 2003, due to 
changes in II's business circumstances, II permanently moves the 
equipment to its plant in Mexico.
    (ii) For 2002, II is allowed a 30-percent additional first year 
depreciation deduction of $300,000 (the adjusted depreciable basis of 
$1,000,000 multiplied by .30). In addition, II's depreciation deduction 
allowable in 2002 for the remaining adjusted depreciable basis of 
$700,000 (the unadjusted depreciable basis of $1,000,000 reduced by the 
additional first year depreciation deduction of $300,000) is $140,000 
(the remaining adjusted depreciable basis of $700,000 multiplied by the 
annual depreciation rate of .20 for recovery year 1).
    (iii) For 2003, the equipment is considered as used predominantly 
outside the United States pursuant to Sec. 1.48-1(g)(1)(i). As a result 
of this change in use, the adjusted depreciable basis of $560,000 for 
the equipment is required to be depreciated under the alternative 
depreciation system of section 168(g) beginning in 2003. However, the 
additional first year depreciation deduction of $300,000 allowed for the 
equipment in 2002 is not redetermined.

    (7) Earnings and profits. The additional first year depreciation 
deduction is not allowable for purposes of computing earnings and 
profits.
    (8) Limitation of amount of depreciation for certain passenger 
automobiles. For a passenger automobile as defined in section 
280F(d)(5), the limitation under section 280F(a)(1)(A)(i) is increased 
by--
    (i) $4,600 for qualified property acquired by a taxpayer after 
September 10, 2001, and before May 6, 2003; and
    (ii) $7,650 for qualified property or 50-percent bonus depreciation 
property acquired by a taxpayer after May 5, 2003.
    (9) Section 754 election. In general, for purposes of section 168(k) 
any increase in basis of qualified property or 50-percent bonus 
depreciation property due to a section 754 election is not eligible for 
the additional first year depreciation deduction. However, if qualified 
property or 50-percent bonus depreciation property is placed in service 
by a partnership in the taxable year the partnership terminates under 
section 708(b)(1)(B), any increase in basis of the qualified property or 
the 50-percent bonus depreciation property due to a section 754 election 
is eligible for the additional first year depreciation deduction.
    (g) Effective date--(1)(i) In general. Except as provided in 
paragraphs (g)(2)

[[Page 1105]]

and (3) of this section, this section applies to qualified property 
under section 168(k)(2) acquired by a taxpayer after September 10, 2001, 
and to 50-percent bonus depreciation property under section 168(k)(4) 
acquired by a taxpayer after May 5, 2003.
    (ii) Except as provided in paragraph (g)(3)(ii) of this section, the 
applicability of this section expires on or before September 4, 2006.
    (2) Technical termination of a partnership or section 168(i)(7) 
transactions. If qualified property or 50 percent bonus depreciation 
property is transferred in a technical termination of a partnership 
under section 708(b)(1)(B) or in a transaction described in section 
168(i)(7) for a taxable year ending on or before September 8, 2003, and 
the additional first year depreciation deduction allowable for the 
property was not determined in accordance with paragraph (f)(1)(ii) or 
(iii) of this section, as applicable, the Internal Revenue Service will 
allow any reasonable method of determining the additional first year 
depreciation deduction allowable for the property in the year of the 
transaction that is consistently applied to the property by all parties 
to the transaction.
    (3)(i) Like-kind exchanges and involuntary conversions. If a 
taxpayer did not claim on a federal tax return for a taxable year ending 
on or before September 8, 2003, the additional first year depreciation 
deduction for the remaining carryover basis of qualified property or 50-
percent bonus depreciation property acquired in a transaction described 
in section 1031(a), (b), or (c), or in a transaction to which section 
1033 applies and the taxpayer did not make an election not to deduct the 
additional first year depreciation deduction for the class of property 
applicable to the remaining carryover basis, the Internal Revenue 
Service will treat the taxpayer's method of not claiming the additional 
first year depreciation deduction for the remaining carryover basis as a 
permissible method of accounting and will treat the amount of the 
additional first year depreciation deduction allowable for the remaining 
carryover basis as being equal to zero, provided the taxpayer does not 
claim the additional first year depreciation deduction for the remaining 
carryover basis in accordance with paragraph (g)(4)(ii) of this section.
    (ii) Paragraph (f)(5)(ii)(F)(2) of this section and paragraph 
(f)(5)(v) of this section apply to a like-kind exchange or an 
involuntary conversion of MACRS property and computer software for which 
the time of disposition and the time of replacement both occur after 
February 27, 2004. For a like-kind exchange or an involuntary conversion 
of MACRS property for which the time of disposition, the time of 
replacement, or both occur on or before February 27, 2004, see Sec. 
1.168(i)-6T(k)(2)(ii). For a like-kind exchange or involuntary 
conversion of computer software for which the time of disposition, the 
time of replacement, or both occur on or before February 27, 2004, a 
taxpayer may rely on prior guidance issued by the Internal Revenue 
Service for determining the depreciation deductions of the acquired 
computer software and the exchanged or involuntarily converted computer 
software (for further guidance, see Sec. 1.168(k)-1T(f)(5) published in 
the Federal Register on September 8, 2003 (68 FR 53000)). In relying on 
such guidance, a taxpayer may use any reasonable, consistent method of 
determining depreciation in the year of disposition and the year of 
replacement. The applicability of paragraph (f)(5) of this section 
expires on or before February 27, 2007.
    (4) Change in method of accounting--(i) Special rules for 2000 or 
2001 returns. If a taxpayer did not claim on the Federal tax return for 
the taxable year that included September 11, 2001, any additional first 
year depreciation deduction for a class of property that is qualified 
property and did not make an election not to deduct the additional first 
year depreciation deduction for that class of property, the taxpayer 
should refer to the guidance provided by the Internal Revenue Service 
for the time and manner of claiming the additional first year 
depreciation deduction for the class of property (for further guidance, 
see section 4 of Rev. Proc. 2002-33 (2002-1 C.B. 963), Rev. Proc. 2003-
50 (2003-29 I.R.B. 119), and Sec. 601.601(d)(2)(ii)(b) of this 
chapter).
    (ii) Like-kind exchanges and involuntary conversions. If a taxpayer 
did not

[[Page 1106]]

claim on a federal tax return for any taxable year ending on or before 
September 8, 2003, the additional first year depreciation deduction 
allowable for the remaining carryover basis of qualified property or 50-
percent bonus depreciation property acquired in a transaction described 
in section 1031(a), (b), or (c), or in a transaction to which section 
1033 applies and the taxpayer did not make an election not to deduct the 
additional first year depreciation deduction for the class of property 
applicable to the remaining carryover basis, the taxpayer may claim the 
additional first year depreciation deduction allowable for the remaining 
carryover basis in accordance with paragraph (f)(5) of this section 
either:
    (A) By filing an amended return (or a qualified amended return, if 
applicable (for further guidance, see Rev. Proc. 94-69 (1994-2 C.B. 804) 
and Sec. 601.601(d)(2)(ii)(b) of this chapter)) on or before December 
31, 2003, for the year of replacement and any affected subsequent 
taxable year; or,
    (B) By following the applicable administrative procedures issued 
under Sec. 1.446-1(e)(3)(ii) for obtaining the Commissioner's automatic 
consent to a change in method of accounting (for further guidance, see 
Rev. Proc. 2002-9 (2002-1 C.B. 327) and Sec. 601.601(d)(2)(ii)(b) of 
this chapter).
