(1) Every person maintaining a place of business, or doing business, in this state, shall collect the tax imposed by this article from the purchaser and remit the tax to the commissioner as hereinafter provided. Failure to collect the tax from the purchaser shall not relieve the seller of liability for payment of the tax.

(2) Any person selling tangible personal property or specified digital products that does not maintain a place of business in this state may be authorized by the commissioner to collect the tax from customers in Mississippi who are liable for its payment, and such person shall remit the tax to the commissioner in the same manner and subject to the same requirements as a person maintaining a place of business or doing business within this state. Such authority may be cancelled at any time when, in the judgment of the commissioner, the tax can be collected more effectively from the purchaser in this state. When the tax has been collected from the purchaser, the seller shall be liable for payment of the tax to the commissioner.

(3) Every person required or authorized to collect the tax shall add to the sales price of tangible personal property, services or specified digital products the amount of the tax imposed on purchaser for the use, storage, or consumption thereof, and, when so added, the tax shall be a debt from the purchaser to the seller until paid, and shall be collectible at law in the same manner as other debts. It shall be unlawful for any person to advertise, hold out, or state to the public or to any customer that the tax herein imposed will be assumed or absorbed by the seller or that any part thereof will be refunded. Said tax shall be stated separately from the sales price on the sales invoice and shown separately on the seller’s records. The purchaser shall pay the tax to the seller as trustee for and on account of the state.
