Border tax adjustments. Do they distort trade?

A familiar proposition asserting the trade-neutrality of uniform, indirect taxes under both the origin and destination principles is re-examined in the context of a world with trade in intermediate goods. A uniform, general sales tax is shown to be trade-neutral under the destination principle, but trade-distorting under the origin principle. A 'stage of processing' value added tax is nondistorting under either border tax adjustment principle. The discussion is then related to a proposed change in GATT rules that would require origin principle administration of the European value added tax.
