CLAIMS FOR REFUNDS

(a) A refund claim must be filed on a form provided by the comptroller, be supported by the original invoice issued by the dealer, and contain: (1) the stamped or preprinted name and address of the dealer; (2) the name of the purchaser or person who received the delivery of fuel; (3) the date of delivery of the fuel; (4) the date the invoice was issued, if different from the date of fuel delivery; (5) the number of gasoline gallon equivalents of compressed natural gas or diesel gallon equivalents of liquefied natural gas delivered; (6) the rate and amount of tax, separately stated from the selling price; and (7) the type of vehicle or equipment into which the fuel is delivered. (b) The purchaser or person who received the delivery of compressed natural gas or liquefied natural gas must obtain the original invoice from the dealer not later than the 30th day after the date the fuel is delivered. If the purchase or delivery of fuel is made through an automated method in which the purchase or delivery is automatically applied to the purchaser or recipient's account, one invoice may be issued at the time of billing that covers multiple purchases or deliveries made during a 30-day billing cycle. (c) The comptroller shall pay a refund by warrant to a person who files a valid refund claim. (d) A person who files a claim for a tax refund on compressed natural gas or liquefied natural gas used for a purpose for which a tax refund is not authorized or who files an invoice supporting a refund claim on which the date, figures, or any material information has been falsified or altered forfeits the person's right to the entire amount of the refund claim filed unless the claimant provides proof satisfactory to the comptroller that the incorrect refund claim filed was due to a clerical or mathematical calculation error. (e) After examining the refund claim and before issuing a refund warrant, the comptroller shall deduct from the amount of the refund the one percent originally deducted by the dealer under Section 162.362(b).
