Multilateral BEPS Convention will enter into force on 1 July 2018

The Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting (the “Convention”) will enter into force on 1 July 2018, marking a significant step in international efforts to update the existing network of bilateral tax treaties and reduce opportunities for tax avoidance by multinational enterprises.

The entry into force of the Convention just one year after the first signature, underlines the strong political commitment to a multilateral approach to fighting base erosion and profit shifting (BEPS) by multinational enterprises. The entry into force follows from the deposit of the fifth instrument of ratification by Slovenia on 22 March 2018. Earlier, the Republic of Austria (22 September 2017), the Isle of Man (19 October 2017), Jersey (15 December 2017), and Poland (23 January 2018) deposited their instruments with the OECD.

“The entry into force of this Multilateral Convention marks a turning point in the implementation of OECD/G20 efforts to adapt international tax rules to the 21st Century,” said OECD Secretary-General Angel Gurría. “We are translating commitments into concrete legal provisions in more than 1,200 tax treaties worldwide. Thanks to this drive by the international community, we are ensuring that multinational companies pay their fair share when it comes to fulfilling tax obligations, like citizens do.”

Change existing tax treaties

The entry into force of the Convention on 1 July 2018 will bring it into legal existence in these five jurisdictions. In accordance with the rules of the Convention, its contents will start to have effect for existing tax treaties as from 2019.
The Convention, negotiated by more than 100 countries and jurisdictions under a mandate from G20 Finance Ministers and Central Bank Governors, will modify existing bilateral tax treaties to swiftly implement the tax treaty measures developed in the course of the OECD/G20 BEPS Project. Treaty measures that are included in the Convention include those on hybrid mismatch arrangements, treaty abuse and permanent establishment. The Convention also strengthens provisions to resolve treaty disputes, including through mandatory binding arbitration, which has been taken up by 28 signatories.
