The owner of a highway motor vehicle who reasonably expects the vehicle to be exempt from the tax under section 4481(a) by reason of § 41.4483-3(c) for a given taxable period shall keep records which indicate the reason that the use of the vehicle is not expected to exceed 5,000 miles on public highways.(d)Records of claimants. Any person claiming refund, credit, or abatement of the tax, interest, additional amount, addition to the tax, or assessable penalty, shall keep a complete and detailed record with respect to the claim.(e)Place and period for keeping records.(1) All records required by the regulations in this part shall be kept, by the person required to keep them, at a convenient and safe location within the United States which is accessible to internal revenue officers.
