Unless a public utility or other service supplier is reimbursed by the local jurisdiction for the actual cost of assisting the local jurisdiction, including, but not limited to, calculating or verifying refunds, distributing refunds, providing data, or providing data processing assistance, the public utility or other service supplier shall not be required to assist the local jurisdiction to refund the tax, including, but not limited to, calculating or verifying refunds, distributing refunds, providing data, or providing data processing assistance.(4) In any action seeking to enjoin collection of taxes imposed on customers of utilities or other service suppliers and collected by the utilities or other service suppliers, in any action seeking declaratory relief concerning the taxes, in any action seeking a refund of the taxes, or in any action seeking otherwise to invalidate the taxes, the sole necessary party defendant in the action shall be the local jurisdiction on whose behalf the taxes are collected and the public utility or other service supplier collecting the taxes shall not be named as a party in the action.(5) If a local jurisdiction repeals the tax, reduces an existing tax rate, changes the tax base, or makes any other changes to the tax that would affect the collection and remittance of the tax, the local jurisdiction shall submit, on and after the effective date of the enactment of the change, a written notification and supply all requisite information to the public utility or service supplier, in accordance with the procedures established by the public utility or service supplier. The public utility or other service supplier shall not be required to implement the changes any earlier than 60 days from the date on which the public utility or other service provider receives the written notification and all other information required by the public utility or other service supplier. If the 60th day is not the first day of a month, then the public utility or other service provider shall implement the changes on the first day of the month following the month in which the 60th day occurs.(6) If a local jurisdiction adopts a new tax, the local jurisdiction shall submit, on and after the effective date of the adoption of the new tax, a written notification to the public utility or other service supplier, in accordance with procedures established by the public utility or other service supplier, requesting that the tax be collected. The public utility or other service supplier shall not be required to begin collecting the tax any earlier than 90 days from the date on which the public utility or other service provider receives written notification and all other information required by the public utility or other service supplier. If the 90th day is not the first day of a month, then the public utility or other service provider shall begin the tax collection on the first day of the month following the month in which the 90th day occurs. Nothing in this section shall be construed to prevent the public utility or other service provider from beginning the tax collection at an earlier date.(b) For purposes of this section, “other service supplier” shall include, but not be limited to, a holder of a state franchise issued pursuant to Section 5840.(c) The Legislature finds and declares that the limitations imposed by this section constitute an issue of statewide concern. The Legislature further finds and declares that the limitations imposed by this section are not municipal affairs as that term is used in Article XI of the California Constitution. Therefore, it is the intent of the Legislature that the limitations imposed by this section apply to all cities, counties, and cities and counties, including chartered cities and chartered counties, any district, including an agency of the state, formed pursuant to general law or special act, for the local performance of governmental or proprietary functions within limited boundaries, and any public or municipal corporation.(Amended by Stats. 2016, Ch. 156, Sec. 1.
