Mauritius: Mauritius Extends Domestic Minimum Top-up Tax Filing Deadline

The MRA issued a communiqué on 28 August 2026 extending the deadline for the submission of returns and payment of the Domestic Minimum Top-up Tax (DMT Tax). This extension applies to multinational enterprise groups subject to the Global Anti-Base Erosion (GloBE) rules under the OECD Pillar Two framework, as implemented in Mauritius through the Finance (Miscellaneous Provisions) Act 2024. The original deadline was 31 August 2026; the new deadline is 30 September 2026.

Key Takeaways

  • Extended Compliance Window: Taxpayers now have an additional month to finalize DMT Tax calculations, gather required data from constituent entities, and submit the consolidated return.
  • Alignment with International Standards: The extension reflects Mauritius’s commitment to aligning with OECD guidance on transitional safe harbours and administrative ease for the first year of implementation.
  • Payment Obligations Unchanged: While the filing deadline is extended, the payment due date for any top-up tax liability remains linked to the original statutory deadline; interest may accrue on late payments.
