Understanding Bahrain’s Domestic Minimum Top-up Tax Framework

Bahrain has introduced a Domestic Minimum Top-up Tax (DMTT), effective for financial years beginning on or after 1 January 2025, aligning with the OECD Pillar Two GloBE Model Rules. This development affects large multinational enterprise (MNE) groups with consolidated annual revenues of EUR 750 million or more in at least two of the four preceding fiscal years.

The DMTT ensures that in-scope MNE groups operating in Bahrain are subject to a minimum effective tax rate of 15%. The framework enables Bahrain to retain primary taxing rights over any top-up tax arising within its jurisdiction, reinforcing compliance with global minimum tax standards.
