Extended Article
On 30 September 2026, the Organisation for Economic Co-operation and Development (OECD) released the full version of the OECD Model Tax Convention on Income and on Capital (2025). The publication consolidates the text of the Model Convention as it existed on 18 November 2025 and provides a comprehensive resource for policymakers, tax administrations, multinational enterprises, and tax professionals involved in the interpretation and application of international tax treaties.
The OECD Model Tax Convention remains the most influential framework for the negotiation and interpretation of bilateral income tax treaties worldwide. Although individual tax treaties are negotiated between sovereign states, the OECD Model serves as the foundation for a significant majority of modern treaty networks, helping to promote consistency in the allocation of taxing rights between jurisdictions and to reduce instances of double taxation.
Unlike the abbreviated versions that focus primarily on treaty provisions and commentaries, the newly released full version offers a broader and deeper perspective on the evolution of international tax treaty standards. In addition to the treaty articles and accompanying commentaries, the publication includes extensive historical notes and background reports that explain the rationale behind key treaty provisions and document the development of OECD treaty policy over time.
The publication also contains the formal positions of non-member economies regarding specific provisions of the Model Convention. These positions provide valuable insight into areas where countries may diverge from OECD standards when negotiating tax treaties. For businesses operating across multiple jurisdictions, understanding such positions can be important when assessing treaty interpretation risks and potential differences in treaty implementation.
Furthermore, the full version incorporates recommendations adopted by the OECD Council, providing additional context regarding the policy objectives underlying the Model Convention. This reinforces the publication’s role as an authoritative reference for courts, tax administrations, treaty negotiators, and taxpayers seeking guidance on the interpretation of treaty provisions.
The release comes at a time when international tax cooperation continues to evolve rapidly. Developments arising from the OECD/G20 Inclusive Framework, measures addressing base erosion and profit shifting (BEPS), and ongoing discussions surrounding the taxation of the digital economy have increased the importance of treaty interpretation and cross-border dispute prevention. The 2025 OECD Model therefore serves not only as a technical reference but also as a reflection of broader trends in international tax policy.
For multinational groups, the publication provides valuable guidance when evaluating withholding tax relief, permanent establishment risks, treaty residency issues, mutual agreement procedures, and the allocation of taxing rights between jurisdictions. Tax advisers and legal practitioners are also expected to rely on the updated commentaries and historical materials when supporting treaty interpretations and resolving international tax disputes.
The full version of the 2025 OECD Model Tax Convention is available through the OECD’s official publication platform and represents an important reference point for international tax professionals seeking a complete understanding of current OECD treaty standards.
