26 U.S. Code § 6038C - Information with respect to foreign corporations engaged in U.S. business
The rules of paragraph (3) shall apply to any transaction between the reporting corporation and any related party who is a foreign person unless such related party agrees (in such manner and at such time as the Secretary shall prescribe) to authorize the reporting corporation to act as such related party’s limited agent solely for purposes of applying sections 7602, 7603, and 7604 with respect to any request by the Secretary to examine records or produce testimony related to any such transaction or with respect to any summons by the Secretary for such records or testimony. The appearance of persons or production of records by reason of the reporting corporation being such an agent shall not subject such persons or records to legal process for any purpose other than determining the correct treatment under this title of any transaction between the reporting corporation and such related party.
If the rules of this paragraph apply to any transaction or item, the treatment of such transaction (or the amount and treatment of any such item) shall be determined by the Secretary in the Secretary’s sole discretion from the Secretary’s own knowledge or from such information as the Secretary may obtain through testimony or otherwise.
For purposes of this section, the terms “related party”, “foreign person”, and “records” have the respective meanings given to such terms by section 6038A(c).
