Tax Discrimination and Capital Neutrality

quot;Tax discriminationquot; is an increasingly important legal concept for international trade and cross-border investment. Commentators have observed that the nondiscrimination article found in thousands of tax treaties based on the OECD Model lacks a coherent guiding principle, and in my remarks, I will argue that the explanation for the incoherence of the nondiscrimination article lies in fundamental uncertainty regarding the purpose and function of tax treaties. Furthermore, I am skeptical of recent suggestions from international tax policymakers that the tax treaty nondiscrimination principle should be brought in line the European Union conception of discrimination. Instead, I would urge you as OECD member state representatives to conduct a more fundamental reconsideration of the goals of tax treaties and what those goals mean for the nondiscrimination article. As requested, I will dedicate part of my remarks to describing my understanding of how various legal prohibitions on tax nondiscrimination relate to the familiar international tax neutrality benchmarks of capital import neutrality (CIN) and capital export neutrality (CEN)
