Singapore signed the GloBE Information Reporting Multilateral Competent Authority Agreement (GIR MCAA) on 14 April 2026 under the OECD/G20 Inclusive Framework’s Pillar Two, enabling the automatic exchange of GloBE Information Returns between tax authorities.
Singapore signed the Multilateral Competent Authority Agreement on the Exchange of GloBE Information (GIR MCAA) under Pillar Two of the OECD/G20 Inclusive Framework’s Two-Pillar Solution on 14 April 2026.
The agreement establishes a framework developed by the OECD/G20 for the automatic exchange of tax information under the Global Anti-Base Erosion (GloBE) Rules. It enables large multinational enterprises to submit a single centrally filed GloBE Information Return, which is then shared with all relevant tax administrations.
This centralised filing system is intended to reduce compliance costs and administrative burdens for businesses, while ensuring that tax authorities receive the necessary information to apply global minimum tax rules effectively.
The agreement also sets out a standardised reporting format, secure data transmission procedures, and confidentiality requirements for participating jurisdictions. In addition, accompanying guidance clarifies key definitions, reporting timelines, and processes for correcting errors in submitted filings.
Overall, the GIR MCAA supports greater international tax cooperation in addressing challenges arising from the digital economy and the implementation of global minimum tax standards.
