43. Since the provisions of the BEPS MLI first started to take effect, in 2019, the BEPS MLI has rapidly strengthened the bilateral tax treaty network of jurisdictions that ratified it. The number of agreements between members of the Inclusive Framework that became compliant with the BEPS MLI has increased steadily by the hundreds each year, exceeding 1,120 as of 31 May 2023. This number continues to increase, on an ongoing basis, as additional Signatories ratify the BEPS MLI. As in previous years, the peer review continues to reveal an important difference in the progress made on implementing the minimum standard by jurisdictions that have ratified the BEPS MLI compared with other jurisdictions.
44. Over the past year, eight jurisdictions that are members of the Inclusive Framework have ratified the BEPS MLI: Armenia, Bulgaria, Côte d'Ivoire, Mexico, Papua New Guinea, South Africa, Tunisia and Viet Nam. 1
45. On average, around 55% of the treaty networks of jurisdictions for which the BEPS MLI started to take effect as of 1 January 2023,2 are compliant with the minimum standard in 2023, as shown in the Table 2.1.
46. For the jurisdictions that ratified the BEPS MLI after October 2022,3 the relevant provisions of the BEPS MLI had generally not yet started to take effect for their agreements on 31 May 2023. This is because provisions of the BEPS MLI can generally only start to take effect for an agreement after a period of time that follows the latest of the dates on which the BEPS MLI enters into force for each of the partners to an agreement. This period could roughly amount to a year from the latest ratification.4
47. As observed in prior peer reviews, while the jurisdictions that ratified the BEPS MLI made good progress in the implementation of the minimum standard, those that did not sign or ratify the BEPS MLI made comparatively little progress, in general, in implementing the minimum standard. Only around 15% of the agreements concluded by those jurisdictions are compliant.
48. The successive peer reviews therefore continue to demonstrate the importance of swift ratification of the BEPS MLI. All signatories to the BEPS MLI that have not yet ratified it are therefore encouraged to do so.
