GMT Compliance
The calm before the storm

Introduction of Global Minimum Tax (GMT) as a key ingredient of OECD’s BEPS Pillar Two framework signals a transformative era in international taxation. It demands immediate and strategic responses from multinational enterprises to reduce the risk of non-compliance. 

The calm before the storm

In response to the GMT rules & guidelines issued by OECD, governments of various countries like UK, Japan, South Korea and many EU countries have formally enacted GMT related laws. Many other countries have announced their interest in implementing GMT effective 2024 and 2025. Singapore announced in its Budget 2023 that it will implement GloBE rules and a QDMTT (referred to as the DTT) for fiscal years starting on or after 1 January 2025. Malaysia also confirmed that they will enact the Pillar Two GloBE rules from 2025. Vietnam passed a resolution to implement the Pillar Two Global Minimum Tax in Vietnam with effect from January 1, 2024.

GMT Compliance is Complex

Considering that multinationals need to collate data from 150+ sources to ensure GMT compliance, end-to-end automation in tax processes is essential. Additionally, effective knowledge management for adherence to evolving BEPS Pillar Two standards is critical.

The 2026 Fallacy

Surprisingly, many businesses feel they have enough time to start working towards GMT implementation due to the Transitional Safe Harbor provisions. What they fail to register is that it is applicable only till December 2026, a deadline merely 3 years away. A duration insufficient for businesses to integrate complexities of GMT implementation in their tax technology, unless they start NOW.

Key Takeaways

This whitepaper – Embracing the Corporate Global Minimum Tax: A Call to Action for Finance Leaders – highlights how the GMT rules & guidelines issued by OECD affect the laws being framed by each country and call for compliance and readiness now.
