(ii) Making that record available for inspection upon request by the Commissioner.
(2) The record described in this paragraph (a) must be retained and kept available for inspection for the 3-year period following the close of the return period to which that record relates.
(3) The person may choose any form of documentation to be used under this section as a record of the signing tax return preparers employed during a return period. The record, however, must disclose on its face which individuals were employed as tax return preparers during that period.
(i) For purposes of this section, any individual who, in acting as a signing tax return preparer, is not employed by another tax return preparer shall be treated as his or her own employer.
