Louisiana Revised Statutes Tit. 47, § 337.81.1. Board of Tax Appeals; finding of overpayment upon appeal from assessment

If the Board of Tax Appeals, pursuant to a hearing of an appeal from an assessment of the collector in accordance with the provisions of R.S. 47:337.51, 337.53, or 337.54, finds that there is no tax due and further finds that the taxpayer has made a refundable overpayment of the tax for the period for which the collector asserted the claim for additional tax, the Board of Tax Appeals shall have jurisdiction to determine the amount of the overpayment, and to order that the amount of overpayment be refunded or credited to the taxpayer; however, the Board of Tax Appeals shall not order a refund or credit unless, as part of its decision, it determines that either the petition of appeal in which the refund or credit was requested was filed within the period set out in R.S. 47:337.79, or that a claim for the refund or credit had been filed with the collector within that period.
