(a) Each distributor or importer shall remit to the supplier or permissive supplier, as applicable, the motor fuel tax levied by Section 40-17-325 due on motor fuel removed at a terminal rack. At the election of a licensed distributor or licensed importer, the supplier or permissive supplier may not require the licensed distributor or licensed importer to pay the tax levied by Section 40-17-325 earlier than one business day before the date the supplier or permissive supplier is required to pay the tax to this state. An election under this subsection is subject to the condition that remittances by the licensed distributor or licensed importer of all tax due to the supplier or permissive supplier shall be paid by electronic funds transfer. An election under this subsection may be terminated by the supplier or permissive supplier if the licensed distributor or licensed importer does not make timely payments to the supplier or permissive supplier as required by this subsection.

(b) A licensed exporter shall remit destination state tax due on motor fuel removed at a terminal rack to the supplier of the motor fuel. If the laws of the destination state prohibit the collection of the destination state's tax, the tax levied by Section 40-17-325 shall be collected.

(c) All tax payments received by a supplier or permissive supplier shall be held in trust by the supplier or permissive supplier until the supplier or permissive supplier remits the tax payment to this state or to another state, and the supplier or permissive supplier shall constitute the trustee for the tax payments.

(d) A licensed distributor or importer that timely pays the tax due a supplier or permissive supplier as required in this section, may deduct from the amount otherwise due to the supplier or permissive supplier a discount of four tenths of one percent (.004) of the amount of tax payable. The discount covers the expense of furnishing a bond and losses due to shrinkage and evaporation. A supplier or permissive supplier may not directly or indirectly deny the discount to a licensed distributor or licensed importer that timely pays the tax due the supplier or permissive supplier as required by this section.
