  Caution: For instructions on how to make a one-time claim for the alternative fuel credit for the first, second, and third calendar quarters of 2022, 
  see the instructions and Notice 2022-39. For the fourth calendar quarter of 2022 and later, the alternative fuel credits must first be taken on Form 
  720, Quarterly Federal Excise Return, as a credit against your alternative fuel or compressed natural gas (CNG) tax liability. If you have this tax 
  liability and you didn’t make the claim on Form 720, Schedule C, as a credit against that liability, you must first file Form 720-X, Amended 
  Quarterly Federal Excise Tax Return, before Schedule 3 (Form 8849) can be used for the refund. You can’t claim any amounts on Form 8849 that 
  you claimed (or will claim) on Form 720, Schedule C; Form 720-X; or Form 4136, Credit for Federal Tax Paid on Fuels or Form 8864, Biodiesel, 
  Renewable Diesel, or Sustainable Aviation Fuels Credit.

2 Biodiesel, Renewable Diesel, or Sustainable Aviation Fuel (SAF) Mixture Credit
  Biodiesel or renewable diesel mixtures. Claimant produced a mixture by mixing biodiesel with diesel fuel, or produced a mixture by mixing 
  renewable diesel with liquid fuel (other than renewable diesel). The biodiesel used to produce the biodiesel mixture met ASTM D6751 and met 
  EPA’s registration requirements for fuels and fuel additives. The renewable diesel used to produce the renewable diesel mixture was derived 
  from biomass, met EPA’s registration requirements for fuels and fuel additives, and met ASTM D975, D396, or other equivalent standard 
  approved by the IRS. The biodiesel or renewable mixture was sold by the claimant to any person for use as a fuel or was used as a fuel by the 
  claimant. Sustainable aviation fuel (SAF) mixtures. Claimant produced a qualified mixture by mixing SAF with kerosene. The qualified 
  mixture was produced by the claimant in the United States, such mixture was used by the claimant (or sold by the claimant for use) in an 
  aircraft, such sale or use was in the ordinary course of a trade or business of the claimant, and the transfer of such mixture to the fuel tank of 
  such aircraft occurred in the United States. The SAF used to produce the qualified mixture is the portion of liquid fuel that isn't kerosene that (i) 
  either (A) meets the specifications of one of the ASTM D7566 Annexes, or (B) meets the specifications of ASTM D1655 Annex A1, (ii) isn’t 
  derived from coprocessing an applicable material (or materials derived from an applicable material) with a feedstock that isn't biomass, (iii) isn’t 
  derived from palm fatty acid distillates or petroleum, and (iv) has been certified in accordance with section 40B(e) as having a lifecycle 
  greenhouse gas emissions reduction percentage of at least 50 percent. For all claims. Claimant has attached the appropriate certificates and, 
  if applicable, appropriate reseller statements. Claimant has no reason to believe that the information in the certificate or statement is false. See 
  the instructions for additional information and requirements.
