Foreign branch separate unit Explained
P is a domestic corporation that carries on business operations in Country X. Those operations constitute a “foreign branch” as defined in Treas. Reg. § 1.367(a)-6T(g)(1), but they do not constitute a permanent establishment under the U.S.–Country X income tax convention.
Although the Country X activities would otherwise constitute a foreign branch separate unit as described in Treas. Reg. § 1.1503(d)-1(b)(4)(i)(A), the exception under Treas. Reg. § 1.1503(d)-1(b)(4)(iii) applies because the activities do not rise to a permanent establishment. As a result, the Country X business operations are not a foreign branch separate unit, and P’s year 1 loss is not subject to the dual consolidated loss (DCL) rules.
The outcome flips if P instead carries on the same Country X operations through a hybrid entity such as DE1ₓ. In that case the permanent-establishment exception does not apply, the operations do constitute a foreign branch separate unit, and the year 1 loss would be subject to the DCL rules.
