The Interaction of Tax and Non-Tax Treaties

This background note consists of two parts. Part one provides an overview of the extent to which tax matters are currently covered in non-tax treaties. This discussion focuses on the general agreement on tariffs and trade (GATT)/World Trade Organization (WTO) agreement and the North American free trade agreement (NAFTA) (which cover direct tax measures only to a limited extent) and the European Community (EC) treaty (which covers direct tax measures more broadly). Part two outlines the issues raised when tax matters are covered in non-tax treaties.
