SECTION 6. CLAIMS; MAKING A

Internal Revenue Bulletin 2023-2 · 2026-10-03 edition · updated 2026-10-04 · United States

CLAIM; CLAIM REQUIREMENTS

.01 In general . In order to qualify for a SAF credit, the claimant must produce, then use or sell for use, a qualified mixture that meets all requirements set forth in this notice. The producer or importer of the sustainable aviation fuel must also be registered under § 4101. See also §§ 40B(f) (1), 6426(k)(3). See section 6.04 of this notice for the claim requirements applicable to a SAF qualified mixture produced under ASTM D7566.

.02 Claimant . The person eligible to claim the SAF credit is the person who produces the qualified mixture, assuming all other statutory requirements are met. With respect to a SAF qualified mixture, the person who produces the SAF qualified mixture does not have to be the same person that produced or imported the SAF synthetic blending component. With respect to a SAF co-processed qualified mixture, the person who produces the SAF co-processed qualified mixture is the proper claimant.

.03 Making a claim . (1) Excise tax claims under §§ 6426(k) and 6427(e)(1); refundable income tax claims under § 34(a)(3) .

(a) In general . First, the claimant must claim an excise tax SAF credit under § 6426(k), along with any credit under § 6426(c) or (e) against its § 4081 excise tax

liability. To the extent that the SAF credit under § 6426(k) (along with the sum of any credit under § 6426(c) or (e)) exceeds the claimant’s § 4081 liability for a particular quarter, the claimant may claim a payment under § 6427(e)(1) or a refundable income tax credit under § 34(a)(3). A claimant may only make one claim for each gallon of sustainable aviation fuel used in a qualified mixture. A claimant may not make a claim under § 6427(e)(1) or § 34(a)(3) for an amount that will be claimed or is required to be claimed under § 6426(k).

(b) Procedure for making a claim . A claimant claiming an excise tax SAF credit under § 6426(k) must first make the claim on a Form 720, Quarterly Federal Excise Tax Return, if reporting excise tax liability, in accordance with the instructions for that form. For federal income tax purposes, a claimant’s expense for the § 4081 excise tax, whether taken as a deduction or as a component of cost of goods sold, is reduced by the amount of the excise tax credit under § 6426(k). See gener- ally Exxon Mobil Corp. v. United States, 43 F.4th 424 (5th Cir. 2022). The payment under § 6427(e)(1) is claimed on Form 720 or Form 8849, Schedule 3, Certain Fuel Mixtures and the Alternative Fuel Credit, in accordance with the instructions for those forms. A person may not make a claim on a Form 8849, Schedule 3 for an amount that is claimed (or will be claimed) on Form 720, Form 720X, Amended Quarterly Federal Excise Tax Return, or Form 4136, Credit for Federal Tax Paid on Fuels .

The § 34(a)(3) refundable income tax credit is claimed on Form 4136 in accordance with the instructions for that form, for amounts otherwise allowable under § 6427(e)(1), but that were not claimed on Form 720 or Form 8849, Schedule 3.

Although the SAF credit applies to fuel sold or used after December 31, 2022, a claimant will be ineligible to make a claim immediately after the credit goes into effect due to the registration requirements imposed by §§ 40B and 6426(k). In general, a claimant will be able to file an amended return (Form 720X) to claim a credit under § 6426(k) with respect to qualified mixtures produced beginning on January 1, 2023, once the appropriate persons are registered and the other requirements of

this notice are met. Similarly, a claimant will be able to use § 34(a)(3) to claim a refundable income tax credit, which it would otherwise be eligible to claim as a payment under § 6427(e)(1).

(2) Nonrefundable income tax credit . The § 40B credit is a § 38 general business credit. A claimant may make this claim on Form 8864, Biodiesel, Renewable Diesel, and Sustainable Aviation Fuels Credit, in accordance with the instructions for that form.

Section 87 provides that gross income includes the SAF credit determined with respect to the taxpayer for the taxable year under § 40B(a). Therefore, a claimant must include the amount of the § 40B credit in its gross income.

The amount of the credit determined under § 40B with respect to any sustainable aviation fuel must be properly reduced to take into account any benefit provided with respect to such sustainable aviation fuel solely by reason of the application of § 6426(k) or 6427(e)(1). See § 40B(g). In addition, for purposes of § 40A (biodiesel and renewable diesel used as fuel), the term biodiesel shall not include any liquid with respect to which a credit may be determined under § 40 or 40B.

A claimant will be ineligible to make a claim immediately after the credit goes into effect due to the registration requirements; however, a claimant generally will be able to file a Form 8864 with an amended income tax return to claim a credit under § 40B once the appropriate persons are registered and the other requirements of this notice are met.

.04 Claim requirements . (1) Applicability . The claim requirements under section 6.04 of this notice apply only to claims made with respect to a SAF qualified mixture produced under ASTM D7566.

(2) Certificate for SAF Synthetic Blending Component . Each claim for a credit or payment under § 34(a)(3), 40B, 6426(k), or 6427(e)(1) with respect to a SAF qualified mixture must contain an original Certificate for SAF Synthetic Blending Component described in section 7.02 of this notice and, if applicable, the Statement(s) of SAF Synthetic Blending Component Reseller described in section 7.03 of this notice. However, in the case of

a certificate and statement that support a claim made on more than one claim form, the certificate and statement are to be included with the first claim and the claimant is to provide information related to the certificate on any subsequent claim in accordance with the instructions applicable to the claim form.

(3) Declaration for SAF Qualified Mix- ture . Each claim for a credit or payment under § 34(a)(3), 40B, 6426(k), or 6427(e) (1) with respect to a SAF qualified mixture must contain a Declaration for SAF Qualified Mixture. The declaration consists of a statement that is signed under penalties of perjury by a person with authority to bind the claimant, is substantially in the same form as the model declaration in Appendix A of this notice, and contains all the information necessary to complete such declaration.

The declaration must contain the Certificate of Analysis (COA) reference number for the COA associated with the SAF qualified mixture, as well as the COA reference numbers for the SAF synthetic blending component and the D1655 kerosene that the claimant blended to produce the SAF qualified mixture. A COA is a document from an unrelated party used to verify the type and quality of fuel used as jet fuel. Separate COAs are generated for each synthetic blending component, for the kerosene used to mix with the synthetic blending component, and for the SAF qualified mixture. The COA reference number for the SAF synthetic blending component must match the COA reference number for the SAF synthetic blending component on the Certificate for SAF Synthetic Blending Component.
