The amount disallowed (as defined in paragraph (q) of § 1.613A-7 ) shall be carried over to the succeeding year and treated as an amount allowable as a deduction pursuant to section 613A(c) for such succeeding year, subject to the 65-percent limitation of section 613A(d)(1). For rules relating to corporations filing a consolidated return, see the regulations under section 1502. With respect to fiscal year taxpayers, except as provided in § 1.613A-1 for taxable years beginning before January 1, 1975, and ending after that date, the limitation shall be calculated on the entire fiscal year and not applied with respect to each short period included in a fiscal year. For purposes of basis adjustments and determining whether cost depletion exceeds percentage depletion with respect to the production from a property, any amount disallowed as a deduction after the application of this paragraph shall be allocated to the respective properties from which the oil or gas was produced in proportion to the percentage depletion otherwise allowable to such properties pursuant to section 613A(c). Accordingly, the maximum amount which may be allowable as a deduction pursuant to section 613A(c) after application of this paragraph (65 percent * adjusted taxable income) shall be allocated to properties for which percentage depletion pursuant to section 613A(c) would be allowed in the absence of the limitation contained in section 613A(d)(1) by application of the same proportion. However, once it is determined that after application of this paragraph cost depletion exceeds percentage depletion with respect to a property, the maximum amount determined under the preceding sentence shall be reallocated among the remaining properties, and the portion of the amount disallowed which is allocable to such property shall be the amount by which percentage depletion pursuant to section 613A(c) before application of this paragraph exceeds cost depletion. See example 1 of paragraph (a)(2) of this section. If the taxpayer becomes entitled to the deduction in a later year (i.e., because the disallowed depletion does not exceed 65 percent of the taxpayer's taxable income for that year after taking account of any percentage depletion deduction otherwise allowable for that year), then the basis of the taxpayer's properties must be adjusted downward (but not below zero) by the amount of the deduction in proportion to the portion of the amount disallowed to the respective properties in the year of the disallowance. However, if the property in question was disposed of by the taxpayer prior to the beginning of such later year, the amount of the deduction in such later year shall be reduced by the difference between the taxpayer's adjusted basis in the property at the time it is disposed of and the adjusted basis which the taxpayer would have had in the property in the absence of the 65-percent limitation.
is tentatively allocated to property M, $29.25 * :
is tentatively allocated to property N, and $16.25 * :
is tentatively allocated to property O.
Since cost depletion of $40 * with respect to property M exceeded the percentage depletion of $19.5 * allowable on such property, A claimed the cost depletion. Accordingly, the only percentage depletion deduction allowable to A pursuant to section 613A(c) for 1975 is with respect to properties N and O. Therefore, the $65 * ceiling applies to the percentage depletion allowable on properties N and O. Of that amount, $41.79 * :
is allocated to property N, and $23.21 * :
is allocated to property O.
Accordingly, A is allowed a total depletion deduction of $105 * ($40 * cost depletion on property M + $41.79 * percentage depletion on property N + $23.21 * percentage depletion on property O). The amount disallowed to A under section 613A(d)(1) is $95 * ($200 * aggregate depletion allowable before application of section 613A(d)(1) - $105 * [$40 * cost depletion allowable on property M + $41.79 * percentage depletion allowable on property N after application of section 613A(d)(1) + $23.21 * depletion allowable on property O after application of section 613A(d)(1)]). For purposes of basis adjustments, $20 * ($60 * percentage depletion before limitation - $40 * cost depletion allowed) of the amount disallowed is allocated to property M. The balance of the amount disallowed of $75 * is allocated $48.21 * :
to property N, and
to property O.
