(a) A license holder may take a credit on a return for the period in which the sale occurred if the license holder paid tax on the purchase of gasoline and subsequently resells the gasoline without collecting the tax to:
(1) the United States government for its exclusive use, provided that a credit is not allowed for gasoline used by a person operating under contract with the United States;
(2) a public school district in this state for the district’s exclusive use;
(3) an exporter licensed under this subchapter if the seller is a licensed supplier or distributor and the exporter subsequently exports the gasoline to another state;
(4) a licensed aviation fuel dealer if the seller is a licensed distributor;
(5) a commercial transportation company or a metropolitan rapid transit authority operating under Chapter 451, Transportation Code, that provides public school transportation services to a school district under § 34.008, Education Code, and that uses the gasoline exclusively to provide those services; or
(6) a nonprofit food bank that delivers or will deliver the gasoline into the fuel supply tank of a motor vehicle with a gross vehicle weight rating of at least 25,000 pounds that is owned by the nonprofit food bank and used to deliver food.
(b) For truck or railcar movements between licensed suppliers or licensed permissive suppliers in which the gasoline removed from the first terminal comes to rest in the second terminal and tax was paid on the first removal, the license holder who receives the gasoline in the second terminal may take the credit.

(c) A license holder may take a credit on a return for the period in which the purchase occurred, and a person who does not hold a license under this subchapter, other than a license as an aviation fuel dealer, may file a refund claim with the comptroller if the license holder or person paid tax on gasoline and the license holder or person:
(1) is the United States government and the gasoline is for its exclusive use, provided that a credit or refund is not allowed for gasoline used by a license holder or person operating under a contract with the United States;
(2) is a public school district in this state and the gasoline is for the district’s exclusive use;
(3) is a commercial transportation company that provides public school transportation services to a school district under § 34.008, Education Code, and the gasoline is used exclusively to provide those services;

(6) is a licensed aviation fuel dealer who delivers the gasoline into the fuel supply tanks of aircraft or aircraft servicing equipment.
(d) A license holder may take a credit on a return for the period in which the purchase occurred if the license holder paid tax on gasoline and the license holder is a licensed interstate trucker who uses the gasoline outside this state in commercial vehicles operated under an interstate trucker license, provided that a credit or refund claimed under this subsection must be taken or filed within the limitation period provided by § 162.128.
(e) A license holder may take credit on a return for the period in which the purchase occurred, and a person who does not hold a license may file a refund claim with the comptroller, if the license holder or person paid tax on gasoline and the gasoline is used in this state by auxiliary power units or power take-off equipment on any motor vehicle, if that use can be accurately measured while the motor vehicle is stationary by any metering or other measuring device or method designed to measure the fuel separately from fuel used to propel or idle the motor vehicle. The comptroller may approve and adopt the use of any device as a basis for determining the quantity of gasoline consumed in those operations for tax credit or tax refund. The climate-control air conditioning or heating system of a motor vehicle that has a primary purpose of providing for the convenience or comfort of the operator or passengers is not a power take-off system, and a credit or refund may not be allowed for the gasoline tax paid on any portion of the gasoline that is used for that purpose. A credit or refund may not be allowed for the gasoline tax paid on that portion of the gasoline used for idling.
(f) A person who paid tax on the purchase of gasoline may claim a credit or seek a refund with the comptroller if 100 or more gallons of gasoline is subsequently exported or lost by fire, theft, or accident. A credit or refund claimed under this subsection must be taken or filed within the limitation period provided by § 162.128.
