S.B. No. 771

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 diesel fuel for which the credit or refund may be

claimed. 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, 2025.
