The report on BEPS Action 14 (Making Dispute ResolutionMechanisms More Effective) contains a commitment by jurisdictions to implement a minimum standard to ensure that they resolve treaty-related disputes in a timely, effective and efficient manner. All members of the Inclusive Framework on BEPS (IF) commit to the implementation of the Action 14 minimum standard which includes timely and complete reporting of mutual agreement procedure (MAP) statistics pursuant to an agreed reporting framework. The 2017 MAP statistics are reported under this new framework. They cover all the members that joined the IF prior to 2018.
