Conflict Settlement in Tax Treaty Law
Although tax treaties generally seek to avoid cross-border disputes by providing a series of rules to allocate tax revenues between the contracting states, the number and magnitude of such disputes continue to grow. This course provides general background regarding the nature of current tax treaty disputes and the practical difficulties encountered in their resolution. It considers the tools currently available for the resolution of such disputes under bilateral tax treaties and other agreements, including the mutual agreement procedure conducted by the competent authorities, advance pricing agreements under bilateral treaties, and the EU multilateral convention on arbitration. The course also discusses the recent OECD and UN consideration of mechanisms to improve dispute resolution, including the broader adoption of mandatory, binding arbitration.
