Section 1.88-1 - Nuclear decommissioning costs(a)In general. Section 88 provides that the amount of nuclear decommissioning costs directly or indirectly charged to the customers of a taxpayer that is engaged in the furnishing or sale of electric energy generated by a nuclear power plant must be included in the gross income of such taxpayer in the same manner as amounts charged for electric energy. For this purpose, decommissioning costs directly or indirectly charged to the customers of a taxpayer include all decommissioning costs that consumers are liable to pay by reason of electric energy furnished by the taxpayer during the taxable year, whether payable to the taxpayer, a trust, State government, or other entity, and even though the taxpayer may not control the investment or current expenditure of the amount and the amount may not be paid to the taxpayer at the time decommissioning costs are incurred. However, decommissioning costs payable to a taxpayer holding a qualified leasehold interest (as described in paragraph (b)(2)(ii) of § 1.468A-1 ) are included in the gross income of such taxpayer, and not in the gross income of the lessor.(b)Examples. The following examples illustrate the application of the principles of paragraph (a) of this section: Example 1. X corporation, an accrual method taxpayer engaged in the sale of electric energy generated by a nuclear power plant owned by X, is authorized by the public utility commission of State A to collect nuclear decommissioning costs from ratepayers residing in State A. With respect to the sale of electric energy, X includes in income amounts that have been billed to customers as well as estimated unbilled amounts that relate to energy provided by X after the previous billing but before the end of the taxable year ("accrued unbilled amounts"). The decommissioning costs are included in the monthly bills provided by X to its ratepayers and the entire amount billed is remitted directly to X. Under paragraph (a) of this section, the decommissioning costs must be included in the gross income of X in the same manner as amounts charged for electric energy (i.e., by including in income decommissioning costs that relate to amounts billed as well as decommissioning costs that relate to accrued unbilled amounts). The same rule would apply if the decommissioning costs charged to ratepayers were separately billed and the amounts billed were remitted to State A to be held in trust for the purpose of decommissioning the nuclear power plant owned by X. In that case, X must include in gross income decommissioning costs that relate to amounts billed as well as decommissioning costs that relate to accrued unbilled amounts.Example 2. Assume the same facts as in Example (1), except that X and M, a municipality located in State A, have entered into a life-of-unit contract pursuant to which (i) M is entitled to 20 percent of the electric energy generated by the nuclear power plant owned by X, and (ii) M is obligated to pay 20 percent of the plant operating costs, including decommissioning costs, incurred by X. Under paragraph (a) of this section, the decommissioning costs that relate to electric energy consumed or distributed by M during any taxable year must be included in the gross income of X for such taxable year. The result contained in this example would be the same if M was a State or an agency or instrumentality of a State or a political subdivision thereof.(c)Cross reference. For special rules relating to the deduction for amounts paid to a nuclear decommissioning fund, see § 1.468A-1 through § 1.468A-5 , 1.468A-7 , 1.468A-8 .(d)Effective date.(1) Section 88 and this section apply to nuclear decommissioning costs directly or indirectly charged to the customers of a taxpayer on or after July 18, 1984, and with respect to taxable years ending on or after such date.(2) If the amount of nuclear decommissioning costs directly or indirectly charged to the customers of a taxpayer before July 18, 1984, was includible in gross income in a different manner than amounts charged for electric energy, such amount must be included in gross income for the taxable year in which includible in gross income under the method of accounting of the taxpayer that was in effect when such amount was charged to customers.T.D. 8184, 53 FR 6804, Mar. 3, 1988
