The G20 Leaders' Declaration has been published following the Summit held 30 November to 1 December 2018 in Buenos Aires, Argentina. With respect to taxation and transparency, the Declaration includes the following:

We will continue our work for a globally fair, sustainable, and modern international tax system based, in particular on tax treaties and transfer pricing rules, and welcome international cooperation to advance pro-growth tax policies. Worldwide implementation of the OECD/G20 Base Erosion and Profit Shifting package remains essential. We will continue to work together to seek a consensus-based solution to address the impacts of the digitalization of the economy on the international tax system with an update in 2019 and a final report by 2020. We welcome the commencement of the automatic exchange of financial account information and acknowledge the strengthened criteria developed by the OECD to identify jurisdictions that have not satisfactorily implemented the tax transparency standards. Defensive measures will be considered against listed jurisdictions. All jurisdictions should sign and ratify the multilateral Convention on Mutual Administrative Assistance in Tax Matters. We continue to support enhanced tax certainty and tax capacity building in developing countries, including through the Platform for Collaboration on Tax.
