    CHAPTER I--INTERNAL REVENUE SERVICE, DEPARTMENT OF THE TREASURY 
                               (CONTINUED)
 
PART 1_INCOME TAXES--Table of Contents
 
Sec. 1.179-5  Time and manner of making election.

    (a) Election. A separate election must be made for each taxable year 
in which a section 179 expense deduction is claimed with respect to 
section 179 property. The election under section 179 and Sec. 1.179-1 
to claim a section 179 expense deduction for section 179 property shall 
be made on the taxpayer's first income tax return for the taxable year 
to which the election applies (whether or not the return is timely) or 
on an amended return filed within the time prescribed by law (including 
extensions) for filing the return for such taxable year. The election 
shall be

[[Page 231]]

made by showing as a separate item on the taxpayer's income tax return 
the following items:
    (1) The total section 179 expense deduction claimed with respect to 
all section 179 property selected, and
    (2) The portion of that deduction allocable to each specific item.

The person shall maintain records which permit specific identification 
of each piece of section 179 property and reflect how and from whom such 
property was acquired and when such property was placed in service. 
However, for this purpose a partner (or an S corporation shareholder) 
treats partnership (or S corporation) section 179 property for which 
section 179 expenses are allocated from a partnership (or an S 
corporation) as one item of section 179 property. The election to claim 
a section 179 expense deduction under this section, with respect to any 
property, is irrevocable and will be binding on the taxpayer with 
respect to such property for the taxable year for which the election is 
made and for all subsequent taxable years, unless the Commissioner 
consents to the revocation of the election. Similarly, the selection of 
section 179 property by the taxpayer to be subject to the expense 
deduction and apportionment scheme must be adhered to in computing the 
taxpayer's taxable income for the taxable year for which the election is 
made and for all subsequent taxable years, unless consent to change is 
given by the Commissioner.
    (b) Revocation. Any election made under section 179, and any 
specification contained in such election, may not be revoked except with 
the consent of the Commissioner. Such consent will be granted only in 
extraordinary circumstances. Requests for consent must be filed with the 
Commissioner of Internal Revenue, Washington, DC 20224. The request must 
include the name, address, and taxpayer identification number of the 
taxpayer and must be signed by the taxpayer or his duly authorized 
representative. It must be accompanied by a statement showing the year 
and property involved, and must set forth in detail the reasons for the 
request.
    (c) Section 179 property placed in service by the taxpayer in a 
taxable year beginning after 2002 and before 2008--(1) In general. For 
any taxable year beginning after 2002 and before 2008, a taxpayer is 
permitted to make or revoke an election under section 179 without the 
consent of the Commissioner on an amended Federal tax return for that 
taxable year. This amended return must be filed within the time 
prescribed by law for filing an amended return for such taxable year.
    (2) Election--(i) In general. For any taxable year beginning after 
2002 and before 2008, a taxpayer is permitted to make an election under 
section 179 on an amended Federal tax return for that taxable year 
without the consent of the Commissioner. Thus, the election under 
section 179 and Sec. 1.179-1 to claim a section 179 expense deduction 
for section 179 property may be made on an amended Federal tax return 
for the taxable year to which the election applies. The amended Federal 
tax return must include the adjustment to taxable income for the section 
179 election and any collateral adjustments to taxable income or to the 
tax liability (for example, the amount of depreciation allowed or 
allowable in that taxable year for the item of section 179 property to 
which the election pertains). Such adjustments must also be made on 
amended Federal tax returns for any affected succeeding taxable years.
    (ii) Specifications of elections. Any election under section 179 
must specify the items of section 179 property and the portion of the 
cost of each such item to be taken into account under section 179(a). 
Any election under section 179 must comply with the specification 
requirements of section 179(c)(1)(A), Sec. 1.179-1(b), and Sec. 1.179-
5(a). If a taxpayer elects to expense only a portion of the cost basis 
of an item of section 179 property for a taxable year beginning after 
2002 and before 2008 (or did not elect to expense any portion of the 
cost basis of the item of section 179 property), the taxpayer is 
permitted to file an amended Federal tax return for that particular 
taxable year and increase the portion of the cost of the item of section 
179 property to be taken into account under section 179(a) (or elect to 
expense any portion of the cost basis of the item of section 179 
property if no prior election was made) without the consent of the 
Commissioner. Any such increase in the

[[Page 232]]

amount expensed under section 179 is not deemed to be a revocation of 
the prior election for that particular taxable year.
    (3) Revocation--(i) In general. Section 179(c)(2) permits the 
revocation of an entire election or specification, or a portion of the 
selected dollar amount of a specification. The term specification in 
section 179(c)(2) refers to both the selected specific item of section 
179 property subject to a section 179 election and the selected dollar 
amount allocable to the specific item of section 179 property. Any 
portion of the cost basis of an item of section 179 property subject to 
an election under section 179 for a taxable year beginning after 2002 
and before 2008 may be revoked by the taxpayer without the consent of 
the Commissioner by filing an amended Federal tax return for that 
particular taxable year. The amended Federal tax return must include the 
adjustment to taxable income for the section 179 revocation and any 
collateral adjustments to taxable income or to the tax liability (for 
example, allowable depreciation in that taxable year for the item of 
section 179 property to which the revocation pertains). Such adjustments 
must also be made on amended Federal tax returns for any affected 
succeeding taxable years. Reducing or eliminating a specified dollar 
amount for any item of section 179 property with respect to any taxable 
year beginning after 2002 and before 2008 results in a revocation of 
that specified dollar amount.
    (ii) Effect of revocation. Such revocation, once made, shall be 
irrevocable. If the selected dollar amount reflects the entire cost of 
the item of section 179 property subject to the section 179 election, a 
revocation of the entire selected dollar amount is treated as a 
revocation of the section 179 election for that item of section 179 
property and the taxpayer is unable to make a new section 179 election 
with respect to that item of property. If the selected dollar amount is 
a portion of the cost of the item of section 179 property, revocation of 
a selected dollar amount shall be treated as a revocation of only that 
selected dollar amount. The revoked dollars cannot be the subject of a 
new section 179 election for the same item of property.
    (4) Examples. The following examples illustrate the rules of this 
paragraph (c):

    Example 1. Taxpayer, a sole proprietor, owns and operates a jewelry 
store. During 2003, Taxpayer purchased and placed in service two items 
of section 179 property--a cash register costing $4,000 (5-year MACRS 
property) and office furniture costing $10,000 (7-year MACRS property). 
On his 2003 Federal tax return filed on April 15, 2004, Taxpayer elected 
to expense under section 179 the full cost of the cash register and, 
with respect to the office furniture, claimed the depreciation 
allowable. In November 2004, Taxpayer determines it would have been more 
advantageous to have made an election under section 179 to expense the 
full cost of the office furniture rather than the cash register. 
Pursuant to paragraph (c)(1) of this section, Taxpayer is permitted to 
file an amended Federal tax return for 2003 revoking the section 179 
election for the cash register, claiming the depreciation allowable in 
2003 for the cash register, and making an election to expense under 
section 179 the cost of the office furniture. The amended return must 
include an adjustment for the depreciation previously claimed in 2003 
for the office furniture, an adjustment for the depreciation allowable 
in 2003 for the cash register, and any other collateral adjustments to 
taxable income or to the tax liability. In addition, once Taxpayer 
revokes the section 179 election for the entire cost basis of the cash 
register, Taxpayer can no longer expense under section 179 any portion 
of the cost of the cash register.
    Example 2. Taxpayer, a sole proprietor, owns and operates a machine 
shop that does specialized repair work on industrial equipment. During 
2003, Taxpayer purchased and placed in service one item of section 179 
property--a milling machine costing $135,000. On Taxpayer's 2003 Federal 
tax return filed on April 15, 2004, Taxpayer elected to expense under 
section 179 $5,000 of the cost of the milling machine and claimed 
allowable depreciation on the remaining cost. Subsequently, Taxpayer 
determines it would have been to Taxpayer's advantage to have elected to 
expense $100,000 of the cost of the milling machine on Taxpayer's 2003 
Federal tax return. In November 2004, Taxpayer files an amended Federal 
tax return for 2003, increasing the amount of the cost of the milling 
machine that is to be taken into account under section 179(a) to 
$100,000, decreasing the depreciation allowable in 2003 for the milling 
machine, and making any other collateral adjustments to taxable income 
or to the tax liability. Pursuant to paragraph (c)(2)(ii) of this 
section, increasing the amount of the cost of the milling machine to be 
taken into account under section 179(a) supplements the portion of the 
cost of the milling machine that was already taken into account by the

[[Page 233]]

original section 179 election made on the 2003 Federal tax return and no 
revocation of any specification with respect to the milling machine has 
occurred.
    Example 3. Taxpayer, a sole proprietor, owns and operates a real 
estate brokerage business located in a rented storefront office. During 
2003, Taxpayer purchases and places in service two items of section 179 
property--a laptop computer costing $2,500 and a desktop computer 
costing $1,500. On Taxpayer's 2003 Federal tax return filed on April 15, 
2004, Taxpayer elected to expense under section 179 the full cost of the 
laptop computer and the full cost of the desktop computer. Subsequently, 
Taxpayer determines it would have been to Taxpayer's advantage to have 
originally elected to expense under section 179 only $1,500 of the cost 
of the laptop computer on Taxpayer's 2003 Federal tax return. In 
November 2004, Taxpayer files an amended Federal tax return for 2003 
reducing the amount of the cost of the laptop computer that was taken 
into account under section 179(a) to $1,500, claiming the depreciation 
allowable in 2003 on the remaining cost of $1,000 for that item, and 
making any other collateral adjustments to taxable income or to the tax 
liability. Pursuant to paragraph (c)(3)(ii) of this section, the $1,000 
reduction represents a revocation of a portion of the selected dollar 
amount and no portion of those revoked dollars may be the subject of a 
new section 179 election for the laptop computer.
    Example 4. Taxpayer, a sole proprietor, owns and operates a 
furniture making business. During 2003, Taxpayer purchases and places in 
service one item of section 179 property--an industrial-grade cabinet 
table saw costing $5,000. On Taxpayer's 2003 Federal tax return filed on 
April 15, 2004, Taxpayer elected to expense under section 179 $3,000 of 
the cost of the saw and, with respect to the remaining $2,000 of the 
cost of the saw, claimed the depreciation allowable. In November 2004, 
Taxpayer files an amended Federal tax return for 2003 revoking the 
selected $3,000 amount for the saw, claiming the depreciation allowable 
in 2003 on the $3,000 cost of the saw, and making any other collateral 
adjustments to taxable income or to the tax liability. Subsequently, in 
December 2004, Taxpayer files a second amended Federal tax return for 
2003 selecting a new dollar amount of $2,000 for the saw, including an 
adjustment for the depreciation previously claimed in 2003 on the 
$2,000, and making any other collateral adjustments to taxable income or 
to the tax liability. Pursuant to paragraph (c)(2)(ii) of this section, 
Taxpayer is permitted to select a new selected dollar amount to expense 
under section 179 encompassing all or a part of the initially non-
elected portion of the cost of the elected item of section 179 property. 
However, no portion of the revoked $3,000 may be the subject of a new 
section 179 dollar amount selection for the saw. In December 2005, 
Taxpayer files a third amended Federal tax return for 2003 revoking the 
entire selected $2,000 amount with respect to the saw, claiming the 
depreciation allowable in 2003 for the $2,000, and making any other 
collateral adjustments to taxable income or to the tax liability. 
Because Taxpayer elected to expense, and subsequently revoke, the entire 
cost basis of the saw, the section 179 election for the saw has been 
revoked and Taxpayer is unable to make a new section 179 election with 
respect to the saw.

    (d) Election or revocation must not be made in any other manner. Any 
election or revocation specified in this section must be made in the 
manner prescribed in paragraphs (a), (b), and (c) of this section. Thus, 
this election or revocation must not be made by the taxpayer in any 
other manner (for example, an election or a revocation of an election 
cannot be made through a request under section 446(e) to change the 
taxpayer's method of accounting), except as otherwise expressly provided 
by the Internal Revenue Code, the regulations under the Code, or other 
guidance published in the Internal Revenue Bulletin.
