If any person subject to the provisions of this chapter, or any rules or regulations promulgated by the commissioner under authority hereof, shall be found to have failed to affix the stamps required, or to have the same affixed as herein provided, or to pay any tax due hereunder, or to have violated any of the provisions of this chapter, or rules and regulations promulgated by the commissioner in the administration of this chapter, there shall be collected from such person, in addition to the tax that may be due, a penalty of fifty percent (50%) of the tax due; and the commissioner, or his duly authorized representative, may make immediate demand upon such person for the payment of all such taxes and penalties. Provided, that the commissioner, for good reason shown, may remit all or any part of the penalties imposed, but the taxpayer must pay all taxes due and interest thereon, at the rate of twelve percent (12%) per annum. The keeping of any unstamped cigarettes or untaxed tobacco at a place of business where such articles are sold, shall be prima facie evidence of intent to violate the provisions of this chapter.

All administrative provisions of the Mississippi Sales Tax Law, including those which fix damages, penalties and interest for nonpayment of taxes and for noncompliance with the provisions of said chapter, and all other requirements and duties imposed upon taxpayers, shall apply to all persons liable for taxes under the provisions of this chapter, and the commissioner shall exercise all the power and authority and perform all the duties with respect to taxpayers under this chapter as are provided in the Sales Tax Law, except where there is conflict, then the provisions of this chapter shall control.
