Louisiana Revised Statutes Tit. 47, § 337.48. Determination and notice of tax due

A. (1) If a taxpayer fails to make and file any return or report required by the provisions of the local ordinance and this Chapter, the collector shall determine the tax, penalty, and interest due by estimate or otherwise. Having determined the amount of tax, penalty, and interest due, the collector shall send by mail a notice to the taxpayer at the address given in the last report filed by him pursuant to the provisions of this Chapter, or to any address that may be obtainable from any private entity which will provide such address free of charge or from any federal, state, or local government entity, including but not limited to the United States Postal Service or from United States Postal Service certified software, setting out his determination and informing the person of his purpose to assess the amount so determined against him after thirty calendar days from the date of the notice.

(2) Notwithstanding any other provision of law to the contrary, a notice issued pursuant to Paragraph (1) of this Subsection to a taxpayer or dealer who fails to make and file any required report or return shall not be appealable to the Board of Tax Appeals for redetermination of the notice of tax due issued pursuant to this Section when the notice is solely for the periods and is in the amount stated on the notice transmitted to such taxpayer or dealer pursuant to Paragraph (1) of this Subsection. Nothing in this Paragraph shall prohibit any taxpayer or dealer from proceeding to file suit pursuant to R.S. 47:337.63 or 337.64, or any other applicable law.
