(c) The requirements of subsection (a) of this Section do not apply to mail order sales nor shall the retail sale of a motor vehicle be considered to be the sale of tires at retail or offering of tires for retail sale. Instead of filing returns, retailers of tires may remit the tire user fee to their suppliers of tires if the supplier of tires is a registered retailer of tires and agrees or otherwise arranges to collect and remit the tire fee to the Department of Revenue, notwithstanding the fact that the sale of the tire is a sale for resale and not a sale at retail. A tire supplier who enters into such an arrangement with a tire retailer shall be liable for the tax on all tires sold to the tire retailer and must (i) provide the tire retailer with a receipt that separately reflects the tire tax collected from the retailer on each transaction and (ii) accept used tires for recycling from the retailer's customers. The tire supplier shall be entitled to the collection allowance of 10 cents per tire, but only if the return is filed timely and only for the amount that is paid timely in accordance with this Title XIV. The retailer of the tires must maintain in its books and records evidence that the appropriate fee was paid to the tire supplier and that the tire supplier has agreed to remit the fee to the Department of Revenue for each tire sold by the retailer. Otherwise, the tire retailer shall be directly liable for the fee on all tires sold at retail. Tire retailers paying the fee to their suppliers are not entitled to the collection allowance of 10 cents per tire. The collection allowance for suppliers, however, shall be allowed only if the return is filed timely and in the manner required by this Title XIV and only for the amount that is paid timely in accordance with this Title XIV.
