(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 §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 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 §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), §1.179-1(b), and §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 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):

(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.
