(b)Copies of returns, schedules, and statements. Every person who is required, by the regulations in this part or by instructions applicable to any form prescribed thereunder, to keep any copy of any return, schedule, statement, or other document, shall keep such copy as a part of his records.
(c)Records of claimants. Any person (including an employee) who, pursuant to the regulations in this part, claims a refund, credit or abatement, shall keep a complete and detailed record with respect to the tax, interest, addition to the tax, additional amount, or assessable penalty to which the claim relates. Such record shall include any records required of the claimant by paragraph (b) of this section and by §§ 31.6001-2 to 31.6001-5, inclusive, which relate to the claim.

(2) Except as otherwise provided in the following sentence, every person required by the regulations in this part to keep records in respect of a tax (whether or not such person incurs liability for such tax) shall maintain such records for at least four years after the due date of such tax for the return period to which the records relate, or the date such tax is paid, whichever is the later. The records of claimants required by paragraph (c) of this section shall be maintained for a period of at least four years after the date the claim is filed.
