OECD Webinar on the Revised Manual on Effective Mutual Agreement Procedures
On 10 February 2026, the OECD will hold a technical webinar from 12:30–13:45 CET to present the 2026 edition of the Manual on Effective Mutual Agreement Procedures. The 2026 revised Manual updates and expands the original 2007 Manual, reflecting recent developments in international tax cooperation and dispute resolution. It aims to strengthen tax certainty by promoting more comprehensive practical guidance and best practices for the effective conduct of the mutual agreement procedure (MAP) under tax treaties, for use by both competent authorities and taxpayers. The updated Manual also includes practical guidance on MAP arbitration, which was not addressed in the original version.
During the webinar, senior OECD officials and tax practitioners will present the key elements of the revised Manual, including close to 60 best practices covering each stage of the MAP process, measures aimed at the proactive prevention of disputes, and guidance on the organisation of an efficient and effective competent authority function.
The session will offer government officials, business stakeholders and tax practitioners insights into the revised Manual as an end-to-end resource for navigating the MAP process and strengthening cross-border tax dispute resolution. Those interested to participate can register at this link.
EU Parliament Hearing on Single Market Tax Barriers & Cost of Non-Europe in Tax Harmonisation
At its meeting on 27 January 2026, the European Parliament’s Subcommittee on Tax Matters (FISC) held a public hearing on “Tackling tax obstacles in the Single Market”, alongside a presentation of the European Parliamentary Research Service (EPRS) Cost of non-Europe report on EU tax policy harmonisation.
Speakers highlighted the scale of tax fragmentation across the EU, pointing to the very high number of national tax expenditures which contribute to duplicated compliance obligations. SMEs, representing around 95% of EU businesses, were estimated to lose more than one fifth of turnover to tax compliance, while transfer pricing disputes continue to increase amid divergent national definitions and thresholds.
The Commission indicated that a broad simplification package is planned for June, including a review of around 15 tax directives, the removal of unused reporting requirements and consideration of lighter compliance for groups within scope of Pillar Two, given the global 15% minimum tax. Possible repeal of overlapping rules, including ATAD, was also referenced.
The hearing discussed potential short-term improvements, such as simplified compliance pathways for SMEs, faster and more accessible tax rulings, and mandatory escalation mechanisms in joint audits to prevent lengthy disputes.
The study concluded that targeted EU-level coordination, rather than full harmonisation, could best reduce compliance costs, strengthen enforcement and limit arbitrage in areas including wealth taxation, cryptoassets, digitalisation of tax administration and tax compliance.
