Louisiana Administrative Code
Title 61 - REVENUE AND TAXATION
Part I - Taxes Collected and Administered by the Secretary of Revenue
Chapter 9 - Hazardous Waste Tax
Section I-917 - Records Requirements

A. Every person required to pay, collect, or remit the tax imposed under this Chapter shall keep a permanent record of all production, handling, storage, disposal, shipment, and receipt of hazardous waste by him in sufficient detail to be of value in determining the correct tax liability under this Chapter. These records must be kept whether or not the person believes the tax imposed by this Chapter is applicable.

B. Whenever the dry-weight of a waste is used as the basis for computing the tax on a return, full documentation of the facts and methodology used in calculating the dry-weight must be maintained. This documentation includes, but is not limited to, testing procedures followed, test results obtained, assumptions made, and the basis for assumptions made.

C. Where required records are voluminous, they must be kept in chronological order or in some other systematic order compatible with the taxpayer's regular bookkeeping system which will enable the secretary to verify the accuracy of information contained in tax returns.

D. Records kept on punched cards, magnetic tape, or other mechanical or electronic record-keeping devices are permissible provided the taxpayer makes available all necessary codes and equipment to enable the secretary to audit such records, or provides the secretary with written transcripts of those parts of the records which the secretary wishes to examine.

E. The books and records must contain complete information pertaining to both taxable and non-taxable items which are the subject of taxes imposed herein, and must be retained until the tax period to which they relate has prescribed. Records required by this Section must be available at all times during the regular business hours of the day for inspection by the secretary or duly authorized agents of the secretary.

F. For the purpose of computing, collecting, or auditing the tax imposed by this Chapter, the secretary shall have access to all manifests and records which are required by the Department of Environmental Quality.
