Sponsored By: Senator Tillis, Thomas [R-NC]

Introduced

Summary

Creates a $1-per-gallon renewable natural gas fuel tax credit that would apply to RNG sold or used as motor vehicle, motorboat, or aviation fuel. It ties eligibility to producer registration and certification and ends after December 31, 2035.

Show full summary
  • RNG producers must register and provide certification to make their gas eligible, which determines how many gallons count toward the credit.
  • Sellers or business users of RNG could receive a payment from the Treasury equal to the credit amount for RNG used in their trade or business, with payments made without interest.
  • Blended fuels count only for the contracted and certified gallons in a preexisting contract that specifies quantity and period, and the credit is not available for RNG produced or used entirely outside the United States.

Blended fuels would count only for contract-certified gallons with producer certification. No credit would apply to RNG produced and used entirely outside the United States.
