(b) (i) Any person registered as a distributor of motor fuel selling aviation gasoline to a fixed base operator registered under this article as a "retail seller of aviation gasoline" may exclude the amount of the tax or taxes imposed by this article from the selling price thereof where such aviation gasoline is delivered to the fixed base operator's premises and placed in a storage facility used exclusively for the purpose of fueling airplanes. The commissioner may register as a "retail seller of aviation gasoline" a fixed base operator who makes no sales of aviation gasoline other than retail sales not in bulk delivered directly into the fuel tank of an airplane and who makes no sales of motor fuel other than the foregoing described retail sales of aviation gasoline delivered directly into the fuel tank of airplanes (provided, in no event, shall kero-jet fuel be construed to constitute motor fuel). Such registration shall apply only to the wholesale purchase of only aviation gasoline by such "retail seller of aviation gasoline" and the retail sale by such person of aviation gasoline not in bulk for delivery directly into the fuel tank of an airplane for use in the operation thereof. In no event shall the registration as a "retail seller of aviation gasoline" be deemed to be an authorization to import, or cause to be imported, motor fuel including aviation gasoline, into this state. All the provisions of section two hundred eighty-three-a (except subdivision one) of this article shall be applicable to the registration of "retail sellers of aviation gasoline" with the same force and effect as if the language of such section had been incorporated in full herein and had expressly referred to the registration of "retail sellers of aviation gasoline", with such modification as may be necessary in order to adapt the language so as to apply to the registration of applicants for and persons registered as "retail sellers of aviation gasoline". Provided, however, that if the commissioner is satisfied that certain requirements of such foregoing provisions with respect to registration are not necessary in order to protect tax revenues, the commissioner may waive, limit or modify such requirements with respect to the registration of "retail sellers of aviation gasoline". The department, where applicable, shall coordinate the registration process with respect to a fixed base operator applying for registration as a "retail seller of aviation gasoline" and as a distributor of kero-jet fuel only with the purpose of eliminating any duplicative information or procedures required of the applicant. Every person registered as a "retail seller of aviation gasoline" shall keep complete and accurate records of purchases and sales of aviation gasoline (including individual invoices identifying each purchase or sale of aviation gasoline) to and from such "retail seller of aviation gasoline". The commissioner shall, if it is determined to be appropriate, establish a requirement that a certificate be given by a "retail seller of aviation gasoline" prior to the sale of aviation gasoline pursuant to this paragraph.

(ii) Any person registered as a distributor of motor fuel and also registered as a "retail seller of aviation gasoline" may exclude the amount of the tax or taxes imposed by this article from the selling price thereof on such retail sale of aviation gasoline.

The refund or credit shall accrue at the time the aviation gasoline is delivered and stored as prescribed in subparagraph (i) of paragraph (b) of this subdivision. Claims for refunds or credits shall be presented and refunds or credits shall be made only as authorized by the commissioner, including documentary proof required to substantiate refund claims. * (d)(i) Any person may exclude the amount of the tax or taxes imposed by this article on E85 from the selling price thereof where E85 is delivered to a filling station and placed in a storage tank of such filling station for such E85 to be dispensed directly into a motor vehicle for use in the operation of such vehicle. Any person making a sale of E85 under the circumstances described herein, whereby the tax or taxes otherwise imposed by this article have not been passed through to the purchaser, shall be allowed a refund or credit of the taxes imposed by this article in the amount of such tax or taxes paid by such person on such E85 being sold or included in the price paid by such person for such fuel. Claims for refunds or credits shall be presented, and refunds or credits shall be made, only as authorized by the commissioner under such rules and regulations as the commissioner may prescribe.

Claims for refunds or credits shall be presented, and refunds or credits shall be made, only as authorized by the commissioner under such rules and regulations as the commissioner may prescribe. * NB Repealed September 1, 2021 2. However, the intention of this article is to place the ultimate burden resulting from such tax, so far as possible, on persons who use the public highways of the state for operating motor vehicles thereon, or who use the waterways of the state including any other waterways bordering on the state for operating pleasure or recreational motor boats thereon, and the following refunds are provided to that end, subject to the provisions of subdivision five of this section. 3. (a) Except as otherwise provided in paragraph (b) of this section, any person who shall buy any motor fuel or diesel motor fuel, on which the tax imposed by this article shall have been paid, and shall consume the same in any manner except in the operation of a motor vehicle upon or over the public highways of this state, or in the operation of a pleasure or recreational motor boat upon or over the waterways of the state including waterways bordering on the state, shall be reimbursed the amount of such tax in the manner and subject to the conditions herein provided except that there shall be no reimbursement of tax paid on motor fuel or diesel motor fuel taken out of this state in a fuel tank connected with the engine of a motor vehicle and consumed outside of this state.

(b) Any omnibus carrier which shall buy any motor fuel on which the aggregate tax imposed by section two hundred eighty-four and section two hundred eighty-four-a of this chapter, or any diesel motor fuel on which the aggregate tax imposed by section two hundred eighty-two-a and section two hundred eighty-two-b of this chapter, shall have been paid, shall be reimbursed, in the case of such motor fuel, the amount paid pursuant to such sections two hundred eighty-four and two hundred eighty-four-a in excess of four cents per gallon, and in the case of diesel motor fuel, the amount paid pursuant to such sections two hundred eighty-two-a and two hundred eighty-two-b in excess of six cents per gallon, provided such motor fuel or diesel motor fuel has been consumed by such carrier in the operation of an omnibus in this state. Any taxicab licensee, as defined by subdivision ten of section two hundred eighty-two of this chapter, who or which shall buy any motor fuel on which the aggregate tax imposed by section two hundred eighty-four and section two hundred eighty-four-a of this chapter or any diesel motor fuel on which the aggregate tax imposed by section two hundred eighty-two-a and section two hundred eighty-two-b of this chapter, shall have been paid, shall be reimbursed, in the case of such motor fuel, the amount paid pursuant to such sections two hundred eighty-four and two hundred eighty-four-a in excess of four cents per gallon, and in the case of diesel motor fuel, the amount paid pursuant to such sections two hundred eighty-two-a and two hundred eighty-two-b in excess of six cents per gallon, provided such motor fuel or diesel fuel has been consumed by such licensee in the operation of a taxicab in this state.

(c) All claims for reimbursement shall be in such form and contain such information as the commissioner shall prescribe and shall be filed within three years from (i) the date of the purchase, in the case of the purchaser; or (ii) the date of the sale, in the case of the seller, of the motor fuel so subject to reimbursement. Every such claim shall include a certificate by or on behalf of the party presenting the same to the effect that it is just, true and correct, that no part thereof has been paid, except as stated therein, and that the balance therein stated is actually due and owing. The claimant shall satisfy the department that the claimant has borne the tax and that the motor fuel has been consumed by the claimant in a manner other than the operation of a motor vehicle upon or over the public highways of this state, the operation of a pleasure or recreational motorboat upon or over the waterways of the state including waterways bordering on the state or, in the case of an omnibus carrier, taxicab licensee, nonpublic school operator or volunteer ambulance service, that the claimant has borne the tax and that the amount claimed is the amount of such tax reimbursable under paragraph (b), (d), (e) or (f) of this subdivision. The department may require such further information or proof as it shall deem necessary for the administration of such claim. Claims for reimbursement approved by the department shall be paid from revenues collected under this article and deposited to the credit of the comptroller as hereinafter provided; but no such claims shall be paid unless the department is satisfied that the amount of the tax for which the reimbursement is claimed has actually been collected by the state. The amount of any erroneous or excessive payment to a claimant for reimbursement may be determined by the department and may be recovered from such claimant in the same manner as a tax imposed by this article, provided, however, that any such determination shall be made within three years after the date of such erroneous or excessive payment.

(d) Any omnibus carrier which shall buy motor fuel on which the aggregate tax imposed by section two hundred eighty-four, section two hundred eighty-four-a and section two hundred eighty-four-c of this chapter or any diesel motor fuel on which the aggregate tax imposed by section two hundred eighty-two-a, section two hundred eighty-two-b and section two hundred eighty-two-c of this chapter shall have been paid, shall be reimbursed the amount paid provided such motor fuel or diesel motor fuel has been consumed by such carrier in the operation of an omnibus in local transit service in this state pursuant to a certificate of convenience and necessity issued by the commissioner of transportation of this state or by the interstate commerce commission of the United States or pursuant to a contract, franchise or consent between such carrier and a city having a population of more than one million inhabitants, or any agency of such city.

(f) Any voluntary ambulance service, as defined in section thirty hundred one of the public health law, which shall buy motor fuel on which the tax or taxes imposed by this article shall have been paid shall be reimbursed the amount of such tax in the manner and subject to the conditions herein set forth, provided such motor fuel has been consumed by such volunteer ambulance service vehicle in the course of operating within the state.

(h) Notwithstanding any provision of the law to the contrary, tax paid pursuant to this article in respect to motor fuel or diesel motor fuel purchased by a government entity and paid for by such government entity with a credit card shall be reimbursed or credited to the issuer of the credit card used for such purchase or the fuel distributor designated in accordance with and subject to the provisions of sections eleven hundred thirty-eight, eleven hundred thirty-nine, eleven hundred forty-two, and eleven hundred forty-five of this chapter concerning such credit card issuers, fuel distributors and government entities. Such provisions shall apply with respect to the administration of and procedure with respect to the taxes imposed under this article in the same manner and with the same force and effect as if the language of such provisions had been incorporated in full into this article and had expressly referred to the tax under this article, with such modifications as may be necessary in order to adapt the language of such provisions to the taxes imposed by this article, except to the extent that any such provision is not relevant to this article. 5. If the provisions of this section providing for reimbursement of the amount of the tax paid be held unconstitutional by a court of competent jurisdiction, the other constitutional provisions of this article nevertheless shall stand, it being the express intention of the legislature that even though such provision for reimbursement be held unconstitutional the tax provided for by this article shall be imposed, collected and distributed as provided in this article, regardless in that event of the manner in which the motor fuel is consumed. 6. Moneys paid in error under this article may be refunded. Where motor fuel, upon which the tax imposed by this article has been paid, is sold, under such circumstances that, if the tax had not been paid, the sale would not have been taxable under this article, the tax may be refunded. Refunds shall be made only as authorized by the commissioner under such rules and regulations as the commissioner may prescribe provided an application therefor is filed with the commissioner within three years from the time the erroneous payment was made, or tax paid motor fuel was so sold. Refunds authorized by the commissioner shall be paid from revenues collected under this article and deposited to the credit of the comptroller as hereinafter provided. 7.

Provided, however, the department shall process applications for reimbursement as expeditiously as possible.
