A. The provider of billing services shall collect the tax from the consumer by adding it as a separate charge to the consumer's monthly statement. Until the consumer pays the tax to such provider of billing services, the tax shall constitute a debt of the consumer to the Commonwealth, localities, and the State Corporation Commission. If any consumer receives and pays for electricity but refuses to pay the tax on the bill that is imposed by § 58.1-2900, the provider of billing services shall notify the State Corporation Commission of the name and address of such consumer. If any consumer fails to pay a bill issued by a provider of billing services including the tax that is imposed by § 58.1-2900, the provider of billing services shall follow its normal collection procedures with respect to the charge for electric service and the tax, and upon collection of the bill or any part thereof shall (i) apportion the net amount collected between the charge for electric service and the tax and (ii) remit the tax portion to the State Corporation Commission and the appropriate locality. After the consumer pays the tax to the provider of billing services, the taxes collected shall be deemed to be held in trust by such provider until remitted to the State Corporation Commission and the appropriate locality. When determining the amount of tax to collect from consumers of an electric utility that is a cooperative which purchases, for the purpose of resale within the Commonwealth, electricity from a federal entity that made payments during such taxable period to the Commonwealth in lieu of taxes in accordance with a federal law requiring such payments to be calculated on the basis of such federal entity's gross proceeds from the sale of electricity, the provider of billing services shall deduct from each of the respective tax amounts calculated in accordance with § 58.1-2900 an amount equal to the calculated tax amounts multiplied by the ratio that the total cost of the power, including facilities rental, supplied by said federal entity to said cooperative for resale within the Commonwealth bears to said cooperative's total operating revenue within the Commonwealth for the taxable period. The State Corporation Commission may audit the records and books of said cooperative to verify that the tax imposed by this chapter has been correctly determined and properly remitted.
