OECD/Platform for collaboration on tax – PCT Progress Report 2018 – 2019. The adoption of the Sustainable Development Goals (SDGs) and the Addis Ababa Action Agenda in 2015 has prompted multilateral organizations to expand their work on domestic revenue mobilization (DRM) in countries, particularly developing countries, 1 including through rapidly growing portfolios of tax-related activities. In this context, the Platform for Collaboration on Tax (PCT) was established in 2016 to bring together the experiences and expertise of the four largest multilateral organizations active in tax matters (International Monetary Fund [IMF], Organization for Economic Co-operation and Development [OECD], United Nations [UN], and World Bank Group [WBG]) to enhance cooperation on domestic revenue issues. Over the last three years, the Platform has helped exploit complementarities and synergies among its Partners in their work on tax, while fully respecting the governance mandates and policy positions of each organization. This report provides an update of the work of the PCT during 2018-19. The PCT previously reported on its progress in 2017.2 Going forward, the PCT plans to provide updates on an annual basis to its governing bodies and interested stakeholders.3 Section II of this report provides an update of the PCT work plan. In February 2018, the PCT held its first global conference on taxation and the SDGs. In their closing statement, Partners committed to 14 actions for enhancing coordination, cooperation and collaboration in their work on tax in support of the SDGs (Box 1). To meet the commitments set out in the 14 Action Items, the PCT has begun with the implementation of a comprehensive work plan. The work plan consists of three main work streams: (1) coordination of DRM capacity development activities; (2) analytical activities; and (3) outreach activities. Then, Section III of the report discusses the early experience with Medium-Term Revenue Strategies (MTRS) and draws preliminary lessons. A brief overview of DRM-related activities of PCT Partners is provided in Section IV. As support for capacity development is scaled up, efficiency and effectiveness only gain more importance. Risks of redundancy, as well as support that outpaces countries’ absorption capacity, need to be managed. By collaborating, synergies in support for capacity development can be exploited and comparative advantages leveraged. Partners have identified complementarities in their mandates, tools and ways of working, which are presented in the Note on Complementarities between the Platform Partners, included as Annex 1. Next steps for strengthening collaboration between Partners are included in Section V of this progress report.
