|  | A BILL TO BE ENTITLED | 
|  | AN ACT | 
|  | relating to a credit or refund for diesel fuel taxes paid on diesel | 
|  | fuel used in this state by auxiliary power units or power take-off | 
|  | equipment. | 
|  | BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF TEXAS: | 
|  | SECTION 1.  Section 162.227, Tax Code, is amended by adding | 
|  | Subsection (d-1) to read as follows: | 
|  | (d-1)  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 may file a refund claim with the comptroller, if the | 
|  | license holder or person paid tax on diesel fuel and the diesel fuel | 
|  | is used in this state by auxiliary power units or power take-off | 
|  | equipment on  any motor vehicle.  If the quantity of that diesel | 
|  | fuel 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 the | 
|  | motor vehicle, the comptroller may approve and adopt the use of the | 
|  | device as a basis for determining the quantity of diesel fuel | 
|  | consumed in those operations for a tax credit or tax refund.  If | 
|  | there is no separate metering device or other approved measuring | 
|  | method, the license holder may take the credit and the person who | 
|  | does not hold a license may claim the refund on a percentage of the | 
|  | diesel fuel consumed by each motor vehicle equipped with an | 
|  | auxiliary power unit or power take-off equipment.  The comptroller | 
|  | shall determine the percentage of the credit or 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 tax paid on | 
|  | any portion of the diesel fuel that is used for that purpose.  A | 
|  | credit or refund may not be allowed for the diesel fuel tax paid on | 
|  | that portion of the diesel fuel that is used for idling. | 
|  | SECTION 2.  This Act takes effect September 1, 2009. |
