Section 48.6420-6 - Records to be kept in substantiation of credits or payments(a)In general. Every person making a claim for credit or payment under section 6420 must keep records sufficient to enable the district director to determine whether the person is entitled to credit or payment under section 6420 and, if so, the amount of the credit or payment. No particular form is prescribed for keeping the records, but the records must include a copy of the income tax return or claim and a copy of any statement or document submitted with the return or claim. The records must also show with respect to the taxable year covered by the claim- (1) The number of gallons of gasoline purchased and the dates of purchase,(2) The name and address of each vendor from whom gasoline was purchased and the total number of gallons purchased from each,(3) The number of gallons of gasoline purchased by the claimant and used during the taxable year for farming purposes on a farm of which the claimant is the owner, tenant, or operator,(4) The number of gallons of gasoline used during the taxable year for the purposes described in section 6420(c)(3)(A) and § 48.6420-4(d) (relating to cultivating, raising, or harvesting) by a person other than the owner, tenant, or operator on a farm of which the claimant is the owner, tenant, or operator, and(5) Other information as necessary to establish the correctness of the claim.(b)Acceptable records.(1) Evidence of purchases of gasoline, and the purposes for which it was used, to substantiate claims may include paid duplicate sales invoices or tickets from the gasoline dealer or other vendor, and detailed records of all fuel used which show the amount consumed on a farm for farming purposes and the amount used for other purposes.(2) Records maintained for Federal or State income tax purposes, or to support claims for refund of a State tax on gasoline, may be used to the extent that they contain the information necessary to substantiate the accuracy of the claim for credit under section 6420. However, the records must show separately the number of gallons of gasoline used on a farm for farming purposes.(3) If trucks or other vehicles are used both on and off the farm, an allocation of gasoline used in the vehicle will be required to show separately the number of gallons of gasoline used on a farm for farming purposes in respect of which the claim is made.(4) If the owner, tenant, or operator is entitled under section 6420(c)(4)(A) to claim credit or payment in respect of gasoline used on the person's farm by another person other than an owner, tenant, or operator of the farm for a purpose described in section 6420(c)(3)(A) and § 48.6420-4(d) , the claimant must have records showing (i) the name and address of the person who performed the farming operation,(ii) a description of the type of work (such as plowing, threshing, combining, etc.) and the type of equipment used,(iii) the date or dates on which the work was done, and(iv) the number of gallons of gasoline so used on the claimant's farm.(c)Place and period for keeping records.(1) All records required by this section must be kept by the claimant at a convenient and safe location within the United States which is accessible to internal revenue officers and shall during normal business hours be available for inspection by internal revenue officers. If the claimant has a principal place of business in the United States, the records must be kept at that place of business.(2) Records required to substantiate a claim under section 6420 must be maintained for a period of at least 3 years from the last date prescribed for the filing of the claim for credit or payment.T.D. 8043, 50 FR 32038, Aug. 8, 1985
