The prepayment requirement provided for in this Section does not apply to liquid propane gas.
    (b) Beginning on July 1, 2000 and through December 31, 2000, the Retailers' Occupation Tax paid to the distributor, supplier, or other reseller shall be an amount equal to $0.01 per gallon of the motor fuel, except gasohol as defined in Section 2-10 of this Act which shall be an amount equal to $0.01 per gallon, purchased from the distributor, supplier, or other reseller.
    (c) Before July 1, 2000 and then beginning on January 1, 2001 and through June 30, 2003, the Retailers' Occupation Tax paid to the distributor, supplier, or other reseller shall be an amount equal to $0.04 per gallon of the motor fuel, except gasohol as defined in Section 2-10 of this Act which shall be an amount equal to $0.03 per gallon, purchased from the distributor, supplier, or other reseller.

    (e) Beginning on January 1, 2011 and thereafter, the Retailers' Occupation Tax paid to the distributor, supplier, or other reseller shall be at the rate established by the Department under this subsection. The rate shall be established by the Department on January 1 and July 1 of each year using the average selling price, as defined in Section 1 of this Act, per gallon of motor fuel sold in the State during the previous 6 months and multiplying that amount by 6.25% to determine the cents per gallon rate. In the case of biodiesel blends, as defined in Section 3-42 of the Use Tax Act, with no less than 1% and no more than 10% biodiesel, and in the case of gasohol, as defined in Section 3-40 of the Use Tax Act, the rate shall be 80% of the rate established by the Department under this subsection for motor fuel. The Department shall provide persons subject to this Section notice of the rate established under this subsection at least 20 days prior to each January 1 and July 1. Publication of the established rate on the Department's internet website shall constitute sufficient notice under this Section. The Department may use data derived from independent surveys conducted or accumulated by third parties to determine the average selling price per gallon of motor fuel sold in the State.
    (f) Any person engaged in the business of selling motor fuel at retail shall be entitled to a credit against tax due under this Act in an amount equal to the tax paid to the distributor, supplier, or other reseller.
    (g) Every distributor, supplier, or other reseller registered as provided in Section 2a or Section 2c of this Act shall remit the prepaid tax on all motor fuel that is due from any person engaged in the business of selling at retail motor fuel with the returns filed under Section 2f or Section 3 of this Act, but the vendors discount provided in Section 3 shall not apply to the amount of prepaid tax that is remitted. Any distributor or supplier who fails to properly collect and remit the tax shall be liable for the tax. For purposes of this Section, the prepaid tax is due on invoiced gallons sold during a month by the 20th day of the following month.
