Third Session of Intergovernmental Negotiations for UN Framework Convention on International Tax Cooperation
The UN Intergovernmental Committee to draft a Framework Convention on International Tax Cooperation is commencing its third session this week, which will run from 10 to 19 November 2025, in Nairobi, Kenya. The session forms part of the Member State–led negotiations to develop a new multilateral framework for international tax cooperation, as mandated by UN General Assembly Resolution 78/230. The session will focus on progressing discussions under Workstream I on the draft Framework Convention, and under Workstream III on Protocol 2 concerning the prevention and resolution of tax disputes.
Discussions during the first week will be organised primarily around the Co-Leads’ Draft Framework Convention Template, covering substantive elements of the proposed convention. These include provisions on the fair allocation of taxing rights, the taxation of high-net-worth individuals, mutual administrative assistance, harmful tax practices, and sustainable development. The Committee is expected to conduct article-by-article deliberations in a series of closed and informal meetings, which will also serve to test possible formulations and areas of convergence. Sessions will address, inter alia, Articles 4–10 of the draft, including the interrelationship between tax cooperation and environmental, social and economic development objectives.
In the second week, the Committee will turn to Protocol 2 on dispute prevention and resolution, guided by the Co-Leads’ Concept Note on Ideas for Potential Solutions. This note proposes a menu of optional mechanisms, including mutual agreement procedures (MAP), joint audits, mediation, and arbitration, with a particular emphasis on flexibility and accessibility for developing countries. Issues such as optionality, scope of application, support for “no-treaty” situations, and the potential role of the UN as a supporting platform for dispute resolution will also be examined.
Written inputs on both Co-Leads documents may still be submitted by Member States and stakeholders by 5 December 2025 at 11:59 PM New York time. Submissions must include a 250-word abstract and may not exceed 3,000 words for Member States or 2,000 words for stakeholders, per document. Further details are available on the Committee’s webpage.
OECD Publishes Preliminary 2025 Report on Mutual Agreement Procedures
The OECD has released a preliminary version of its 2025 Consolidated Information on Mutual Agreement Procedures, with the final edition due for publication in mid-November. The report brings together country-specific information on the operation of Mutual Agreement Procedures (MAPs) under BEPS Action 14 for all Inclusive Framework jurisdictions. It provides an overview of each jurisdiction’s MAP programme, peer-review outcomes and 2024 statistical data, offering a single reference point on global dispute-resolution practices.
The statistical data for 2024 were presented by the OECD at this year’s Tax Certainty Day, forming the centrepiece of discussions on international tax dispute prevention and resolution. The figures show that global MAP inventories have reached record levels, exceeding 6,700 pending cases. While closures increased slightly, new cases once again outpaced resolutions – particularly in transfer pricing disputes. Average resolution times improved modestly, with MAP cases concluding in around 27 months on average, down from 29 months the previous year. Transfer pricing cases remain lengthier, averaging 30.9 months compared with 24.5 months for other cases.
Around 76 % of MAP cases achieved full resolution for taxpayers, and only 4 % were closed without agreement, indicating a high degree of cooperation among competent authorities. The stock of older cases continues to fall, with just 3.3 % dating from before 2016 and more than half of all cases now under two years old.
Transfer pricing disputes continue to dominate MAP activity, representing over 60% of all cases and reflecting ongoing complexity and divergent interpretations of the OECD Transfer Pricing Guidelines. While jurisdictions such as the Netherlands, Canada and Japan report resolution rates above 80%, others face persistent backlogs and extended timelines. The OECD has reiterated the need for consistent implementation of the Action 14 minimum standard and enhanced resources for competent authorities.
The 2025 report also highlights progress in digitalisation and oversight through the MAP Statistics Reporting Framework and the Tax Certainty Hub, which improve transparency and comparability across jurisdictions. The upcoming 2025 peer-review cycle will assess the timely implementation of dispute-prevention measures and follow-up on earlier recommendations.
