35 Miss. Code R. § 5-06-01-100
The following sections are the procedures prescribed by the Chairman of the MSTC for adoption by each taxpayer/licensee and which apply to slot machines, requiring that adequate records of the gross revenue of the taxpayer/licensee be kept to ensure the accurate calculation of gross revenue subject to tax and reliable accounting records. These procedures reflect the minimum required to be adopted by a licensee. Any variations must be comparable or must exceed the following criterion. All procedures or changes to those procedures must be provided to the Chairman in written form prior to implementation. As used in this regulation, an employee "work permit number" may be another identifying employee number used by the licensee, as an example, a partial social security number or a unique employee identification number assigned by the licensee.
