A. Any service user subject to the tax imposed by SMC 3.10.060 or 3.10.070, which produces gas or electricity for self-use; which receives gas or electricity, including any related supplemental services, directly from a nonutility service supplier not under the jurisdiction of this chapter; or which, for any other reason, is not having the full tax collected and remitted by its service supplier, a nonutility service supplier, or its billing agent on the use of gas or electricity in the City, including any related supplemental services, shall report said fact to the Tax Administrator and shall remit the tax due directly to the Tax Administrator within 30 days of such use. In lieu of paying said actual tax, the service user may, at its option, remit to the Tax Administrator within 30 days of such use an estimated amount of tax measured by the tax billed in the previous month, or upon the payment pattern of similar customers of the service supplier using similar amounts of gas or electricity; provided, that the service user shall submit an adjusted payment or request for credit, as appropriate, within 60 days following each calendar quarter. The credit, if approved by the Tax Administrator, may be applied against any subsequent tax bill that becomes due.

B. The Tax Administrator may require said service user to identify its nonutility service supplier and provide, subject to audit, invoices, books of account, or other satisfactory evidence documenting the quantity of gas or electricity used, including any related supplemental services, and the cost or price thereof. If the service user is unable to provide such satisfactory evidence, or, if the administrative cost of calculating the tax in the opinion of the Tax Administrator is excessive, the Tax Administrator may determine the tax by applying the tax rate to the equivalent charges the service user would have incurred if the gas or electricity used, including any related supplemental services, had been provided by the service supplier that is the primary supplier of gas or electricity within the City.
