Tax treaty arbitration

Abstract Traditionally, tax authorities endeavour to resolve their tax treaty disputes among themselves, by amicable settlement through a mutual agreement procedure (commonly known as ‘MAP’ procedure), without involvement from any third parties—neither arbitrators nor mediators. In past years, due to globalization of countries’ economies and spread of tax treaty networks, the number of disputess, their complexity and revenue interest involved have gone up drastically, exceeding many authorities’ capacities, and resulting in MAP cases taking up increasingly more time, or remaining unresolved at all. It is generally expected that the recent OECD/G20 initiated ‘BEPS’ (short for: Base Erosion and Profit Shifting) measures against international tax avoidance will add further to this. Arbitration so far having been hardly tried in practice, the recent arbitration piece under the BEPS multilateral treaty (MLI) and EU Directive on dispute resolution in international tax matters, however, create new momentum. It is now up to tax authorities if they can accustom themselves to the use of arbitration as an ordinary, and in certain circumstances preferable tool for resolving their disputes.
