(a) No later than September 30, 2013, the Department of Revenue shall develop and make available a system which allows any taxpayer required to file and remit a state, county, or municipal sales or use tax or a state, county, or municipal leasing or rental tax or a state, county, or municipal lodgings tax the ability to file and remit such sales and use tax or leasing or rental tax or lodgings tax returns and payments through an electronic single point of filing program. The system shall be known as the Optional Network Election for Single Point Online Transactions or "ONE SPOT." The system shall be available for use by any taxpayer for tax periods after September 30, 2013, provided the taxpayer complies with this article and any rules promulgated by the department for the administration of the system. The ONE SPOT system shall allow for sales and use tax or leasing or rental tax or lodgings tax return filing and tax remittance only and may not provide for the administration or enforcement of local sales and use taxes and rental or leasing and lodgings tax.

(b) There shall be no charge to local taxing jurisdictions for utilization of the ONE SPOT system by taxpayers or the local taxing jurisdiction or its designee. Beginning no later than January 2013, the department shall provide financial assistance of up to one million dollars ($1,000,000) for three years to assist local taxing jurisdictions as necessary to ensure that their local system is capable of effectively interfacing with the ONE SPOT system.

(c) The system developed and implemented pursuant to subsection (a) shall have the capability to allow a taxpayer to file an electronic tax return for state sales and use taxes and leasing or rental taxes and lodgings tax and for each local taxing jurisdiction in which the taxpayer is required to file and remit a sales or use tax or leasing or rental tax or lodgings tax. The electronic tax return shall contain all information included in the standard multiple jurisdictional tax returns developed pursuant to Section 11-51-210, and all information included in the electronic tax return shall be electronically available to each appropriate local taxing jurisdiction without delay. The department shall consult with the State and Local Advisory Committee established in Section 40-23-242 regarding development and implementation of the ONE SPOT system.

(d) As required in Section 11-51-210, every local taxing jurisdiction levying or administering a sales or use tax or leasing or rental tax or lodgings tax shall submit to the department a list of the sales and use taxes and leasing or rental taxes and lodgings taxes levied or administered by that local taxing jurisdiction including current rates and shall submit to the department written notification of any new or amended sales or use tax or leasing or rental tax or lodgings tax. Failure to notify the department may not invalidate the levy of the tax unless otherwise provided for by law; except that the department may not be required to program new sales or use taxes and leasing or rental taxes or lodgings taxes or tax rates in the system until such time as notice is provided as required in this article and pursuant to Section 11-51-210.
