Location Savings and Segmented Factor Input Markets: In Search of a Tax Treaty Solution

This article analyzes the proper bounds of source-based taxation of profits generated when firms outsource factor inputs, such as labor, to achieve cost savings. The article advances arguments grounded in efficiency, treaty text, and international distribution to justify greater source-based taxation than has historically been the case. To implement such expanded taxation, the article proposes a modification to transfer-pricing rules in instances where factor inputs are acquired from affiliates and a modification to the tax treaty rules regarding permanent establishments where factor inputs are acquired from unrelated parties. Finally, the article deals with a range of complications, particularly relating to measurement of economic rents from low cost factor inputs over time and tax competition.
