OECD’s New Guidelines for Global Minimum Tax: Comprehensive Insights for 2025

The OECD Inclusive Framework on Base Erosion and Profit Shifting (BEPS) has released a set of updates to support the coordinated implementation of the global minimum tax under Pillar Two. These guidelines and tools aim to simplify compliance processes, enhance transparency, and ensure a level playing field for multinational enterprises (MNEs).

This release includes several key developments designed to provide clarity and reduce administrative burdens for MNEs, tax professionals, and policymakers.


Key Highlights of the OECD Updates

  1. Compilation of Qualified Domestic Legislation
    The OECD published the Central Record of Legislation with Transitional Qualified Status, outlining jurisdictions whose domestic tax rules have achieved qualified status temporarily. This fast-track process ensures these jurisdictions meet the GloBE Model Rules’ requirements.

  2. Guidance on Article 9.1 of the GloBE Rules
    The new administrative guidance addresses deferred tax assets arising before the global minimum tax’s application. This exclusion ensures the accurate calculation of an MNE group’s effective tax rate, promoting consistency in tax reporting.

  3. Enhanced GloBE Information Return (GIR)
    The updated GIR incorporates stakeholder feedback, simplifying compliance by clarifying reporting obligations and providing a user-friendly notification template for MNE groups. These changes aim to streamline tax reporting across jurisdictions.

  4. Multilateral Competent Authority Agreement (MCAA)

  5. Standardized XML Schema and User Guide
