(a) General rule.
(1) All references in this section to section 614(b) or any paragraph or subparagraph thereof are references to section 614(b) or a paragraph or subparagraph thereof as it existed prior to its amendment by section 226(a) of the Revenue Act of 1964. All references in this section to section 614(d) are references to section 614(d) as it existed prior to its amendment by section 226(b)(3) of the Revenue Act of 1964.
(2) For taxable years beginning before January 1, 1964, in the case of oil and gas wells, a taxpayer may treat under section 614(d) and this section any property as if section 614 (a) and (b) had not been enacted. For purposes of this section, the term property means each separate operating mineral interest owned by the taxpayer in each mineral deposit in each separate tract or parcel of land. Separate tracts or parcels of land exist not only when areas of land are separated geographically, but also when areas of land are separated by means of the execution of conveyances or leases. If the taxpayer treats any property or properties under this section, the taxpayer must treat each such property as a separate property except that the taxpayer may treat any two or more properties that are included within the same tract or parcel of land as a single property provided such treatment is consistently followed. If the taxpayer treats two or more properties as a single property under this section, such properties shall be considered as a single property for all purposes of subtitle A of the Internal Revenue Code of 1954. The taxpayer may not make more than one combination of properties within the same tract or parcel of land. Thus, if the taxpayer treats two or more properties that are included within the same tract or parcel of land as a single property, each of the remaining properties included within such tract or parcel of land shall be treated as a separate property. If the taxpayer has treated two or more properties that are included within the same tract or parcel of land as a single property and subsequently discovers or acquires an additional mineral deposit within the same tract or parcel of land, he may include his interest in such deposit with the two or more properties which are being treated as a single property or he may treat his interest in such deposit as a separate property. If the taxpayer has treated each property included within a tract or parcel of land as a separate property and subsequently discovers or acquires an additional mineral deposit within the same tract or parcel of land, he may combine his interest in such deposit with any one of the separate properties included within the tract or parcel of land, but not with more than one of them since they cannot be validly combined with each other. The taxpayer may not combine properties which are included within different tracts or parcels of land under this section irrespective of whether such tracts or parcels of land are contiguous. The treatment of a property as a separate property or the treatment of two or more properties included within a single tract or parcel of land as a single property under this section shall be binding upon the taxpayer for the first taxable year for which such treatment is effective and for all subsequent taxable years beginning before January 1, 1964. For the continuation of such treatment under §1.614-8 for taxable years beginning after December 31, 1963, see paragraph (d) of §1.614-8. For provisions relating to the first taxable year for which treatment under this section becomes effective, see paragraph (d) of this section.
(b) Treatment consistent with treatment for taxable years prior to 1954. If the taxpayer has treated properties in a manner consistent with the rules contained in paragraph (a) of this section for taxable years to which the Internal Revenue Code of 1939 applies and if the taxpayer desires to treat such properties under section 614(d), then such properties must continue to be treated in the same manner. The provisions of this paragraph may be illustrated by the following examples:
(c) Bases of separate properties previously included in an aggregation under section 614(b). If the taxpayer has made an election under section 614(b) to form an aggregation of operating mineral interests and if such taxpayer subsequently revokes such election for all taxable years for which it was made and treats the properties that are included within such aggregation under section 614(d) and this section by filing the statement required by paragraph (e) of this section, then the adjusted basis of each separate property (as defined in paragraph (a) of this section) that is a part of such aggregation shall be determined as if the taxpayer had made no election under section 614(b). However, if, at the time of the filing of the statement revoking the election under section 614(b), assessment of any deficiency or credit or refund of any overpayment, as the case may be, resulting from such revocation is prevented by the operation of any law or rule of law for any taxable year or years for which the election under section 614(b) was made, then the adjusted basis of each separate property that is a part of the aggregation shall be determined in accordance with the provisions contained in paragraph (a)(2) of §1.614.6 as of the first day of the first taxable year for which the revocation is effective. After determining the adjusted basis of each separate property included within the aggregation, the taxpayer may treat such properties in any manner which is in accordance with paragraph (a) of this section. See, however, paragraph (b) of this section. The provisions of this paragraph may be illustrated by the following examples:
(d) Treatment; when effective. If a taxpayer treats any property in accordance with this section, then such treatment shall be effective for whichever of the following taxable years is the later:
(1) The latest taxable year for which an election could have been made with respect to such property under section 614(b); or
(2) The first taxable year beginning after December 31, 1953, and ending after August 16, 1954, in respect of which assessment of a deficiency or credit or refund of an overpayment, as the case may be, resulting from the treatment of such property under this section, is not prevented by the operation of any law or rule of law on the date such treatment is adopted.
(e) Manner of adopting the treatment of properties under this section. If the taxpayer does not make an election under section 614(b) with respect to a property within the time prescribed for making such an election, then the taxpayer shall be deemed to have treated such property under this section. In such case, the manner in which such property is treated in filing the taxpayer's income tax return for the first taxable year for which the treatment of such property is effective under paragraph (d) of this section shall establish the treatment which must be consistently followed with respect to such property for subsequent taxable years. However, if the income tax return for such first taxable year is filed prior to May 1, 1961, then the taxpayer may adopt the treatment provided for under this section with respect to the property by filing a statement at any time on or before May 1, 1961, with the district director for the district in which the taxpayer's income tax return was filed for the first taxable year for which the treatment of such property is effective under paragraph (d) of this section. Such statement shall set forth the first taxable year for which the treatment of the property under this section is effective, shall revoke any previous elections made with respect to such property under section 614(b), shall state the manner in which such property was treated for taxable years subject to the Internal Revenue Code of 1939, shall state the manner in which such property is to be treated under this section, and shall be accompanied by an amended return or returns if necessary.
(f) Certain treatment under this section precludes election to aggregate under section 614(b) with respect to the same operating unit. If the taxpayer's treatment of any properties that are included within an operating unit (as defined in paragraph (c) of §1.614-2) under section 614(d) and this section would constitute an aggregation under section 614(b) and if such taxpayer elects, or has elected, to form an aggregation within the same operating unit under section 614(b) for any taxable year for which the treatment under section 614(d) is effective, then the election made under section 614(b) shall not apply for any such taxable year.
