This article examines the implementation of the Authorized OECD Approach in Germany, which is problematic, as most German tax treaties are not based on the current article 7 of the OECD Model, potentially resulting in a mismatch in treatment of PEs from a domestic law versus treaty perspective. To remedy this, Germany has enacted an escape clause. This article classifies Germany’s tax treaties, providing a taxonomy of treaties falling under the purview of the escape clause in particular contexts.
