26 CFR § 48.6420-3 - Exempt sales; other payments or refunds available.
(a)Exempt sales. Credits or payments are allowable only for gasoline that was sold by the producer or importer in a transaction that was subject to tax under section 4081. No credit or payment shall be allowed or made under § 48.6420-1 with respect to gasoline which was exempt from the tax imposed by section 4081. For example, a State or local government may not file a claim with respect to any gasoline which it purchased tax free from the producer, even though the State or local government used the gasoline on a farm for farming purposes. Similarly, payment may not be made with respect to gasoline purchased by a State tax free for its exclusive use, as provided in section 4221, which is used on a State prison farm for farming purposes.
(b)Other payments or refunds available. Any amount which, without regard to the second sentence of section 6420(d) and this paragraph (b), would be allowable as a credit or payable to any person under § 48.6420-1 with respect to any gasoline is reduced by any other amount which is allowable as a credit or payable under section 6420, or is refundable under any other provision of the Code, to any person with respect to the same gasoline. Thus, a person who is the ultimate purchaser of gasoline may not file a claim for credit or payment with respect to that gasoline if another person is entitled to claim a payment, credit, or refund with respect to the same gasoline. For example, a State or local government may not file a claim for payment if it has executed, or intends to execute, a written consent to enable the producer to claim a credit or refund for the tax that was paid. See, for example, §§ 48.6416(a)-3(b)(2), 48.6416(b)(2)-2(d), and 48.6416(b)(2)-3(b)(1).
