This document contains final and temporary regulations that provide guidance under sections 6038 and 6038A of the Internal Revenue Code. The final regulations under Sec. 1.6038-2 are revised to remove and replace obsolete references to a form and IRS offices. The temporary regulations clarify the information required to be furnished regarding certain related party transactions of certain foreign corporations and certain foreign-owned domestic corporations. The temporary regulations also increase the amount of certain penalties, and make certain other changes, to reflect the statutory changes made by the Taxpayer Relief Act of 1997 (TRA '97). The text of the temporary regulations also serves as the text of the proposed regulations set forth in this issue of the Federal Register.
