La. Revenue and Taxation § 47:315.4
A taxpayer shall be entitled to a credit for the amount of ad valorem taxes paid on property to which the taxpayer is entitled to a homestead exemption but elects to waive that exemption as provided in R.S. 47:1711. This credit shall be applicable to local sales and use taxes collected by the single tax collector for the parish in which the taxpayer filed the waiver required by R.S. 47:1711(B). The amount of the credit shall be equal to the lesser of the total amount of local sales and use taxes paid by the taxpayer or the total amount of ad valorem taxes that are paid as a result of the waiver of the taxpayer's homestead exemption. The single tax collector shall allocate the credit to each taxing authority in the parish in a proportion equal to the percentage of the total sales tax collections for each taxing authority for the previous calendar year compared to the total sales tax collections for the parish as a whole for the previous calendar year. However, no credit shall be allocated to any taxing authority which does not levy ad valorem taxes subject to the homestead exemption.
