Bahrain’s Domestic Minimum Top-up Tax (DMTT), effective January 1, 2025, targets multinational enterprises (MNEs) with revenues exceeding €750 million, aligning the country with the OECD’s global minimum tax initiative. Unlike other GCC nations with corporate tax regimes, Bahrain focuses solely on taxing large MNEs, maintaining a tax-friendly environment for smaller businesses. While the DMTT may pose compliance challenges for MNEs, such as data standardization and currency management, it offers safe harbor benefits to simplify reporting. This move signals Bahrain’s commitment to global tax reforms and is expected to influence similar tax policies across the GCC. Businesses are urged to prepare by reviewing compliance processes and seeking expert advice.
