La. R.S. 47:337.67 — Suspension and interruption of prescription

A. Sales and use taxes levied by any political subdivision shall prescribe as of three years from the thirty-first day of December of the year in which such taxes became due.
B. The prescriptive period running against any such sales and use tax shall be interrupted by any of the following:
(1) The action of the collector in assessing the amounts of such taxes in the manner provided by law.
(2) The filing of a summary proceeding in court.
(3) The filing of any pleading, either by the collector or the taxpayer, with the Board of Tax Appeals or with any state or federal court.
(4) The filing of a false or fraudulent return.
(5) The failure to file a return, with the intent to defraud.
C. The running of such prescriptive period may also be suspended as follows:
(1) By means of a written agreement between the taxpayer and the collector made prior to the lapse of such period.
(2) With respect to bankruptcy, for any period from the time the taxpayer files for bankruptcy until six months after the bankruptcy case is closed.
(3) By the filing of a claim for refund as to the period for which a refund is requested, which shall suspend prescription for the same period for the collector to determine whether the taxpayer owes any other liability for the same type of tax under the provisions of R.S. 47:337.78.
D.(1) The failure to file any return required to be filed by this Chapter shall interrupt the running of prescription, and prescription shall not commence to run again until the subsequent filing of such return. Once prescription commences to run, the tax, interest, and penalty, or other charge which is reported on such return shall prescribe in three years after the thirty-first day of December of the year of the filing of the return.
(2) However, if a taxpayer who does not file a tax return required to be filed by this Chapter later becomes responsible for the filing of such return due to a decision of the Board of Tax Appeals which has become final, or due to a final court decision which renders a transaction or other activity as taxable, and the laws, regulations, or jurisprudence of this state previously classified that transaction or other activity as nontaxable, this provision shall not apply and prescription shall run as if the taxpayer had timely filed the return.
(3) The interruption of the running of prescription due to the failure to file a return reporting a tax shall not apply to any tax periods for which the collector and the taxpayer have entered into a valid and enforceable voluntary disclosure agreement.
(4) The provisions of the Subsection shall apply only to use tax returns when the amount due exceeds five hundred dollars for the tax levied.
