This document contains temporary regulations that provide guidance relating to the allocation by a partnership of creditable foreign tax expenditures. These temporary regulations are necessary to improve the operation of an existing safe harbor rule that is used for determining whether allocations of creditable foreign tax expenditures are deemed to be in accordance with the partners' interests in the partnership. The text of these temporary regulations also serves as the text of the proposed regulations set forth in the notice of proposed rulemaking (REG-100861-15) published in the Proposed Rules section in this issue of the Federal Register. These regulations affect partnerships that pay or accrue foreign income taxes, and their partners.
