The BEPS Project sets out 15 actions, many of which cannot be tackled without amending bilateral tax treaties. Given the sheer number of treaties in effect, implementing these changes on a treaty-by-treaty basis would be a very lengthy process.
Action 15 of the BEPS Project analysed the possibility of developing a multilateral instrument in order to allow countries to swiftly amend their tax treaties to implement the tax treaty-related BEPS recommendations.

The report [Developing a Multilateral Instrument to Modify Bilateral Tax Treaties]( concluded that such a multilateral instrument is not only feasible but also desirable, and that negotiations for the instrument should be convened quickly. A [mandate]( to set up the ad hoc Group for the development of a multilateral instrument was developed by the OECD Committee on Fiscal Affairs and endorsed by the G20 Finance Ministers and Central Bank Governors at their February 2015 meeting.
