Any locality may by ordinance develop a method for returning surplus real or personal property tax revenues, or both, to taxpayers who are assessed such taxes in any fiscal year in which the locality reports a surplus. The locality may reduce a taxpayer's refund by the amount of any taxes, penalties, and interest that are due from such taxpayer, or any past-due taxes, penalties, and interest that have been assessed within the appropriate period of limitations.
