Eye on Pillar 2:
Updates and Insights
Corptax Eye on Pillar 2 is your hub for recent Pillar 2 developments
and what they mean for you. Check back often for the latest news and perspectives.
Update: Türkiye has extended its initial QDMTT filing deadline
to January 15, 2026. All submissions must be completed directly through Türkiye’s online portal using a manual input workflow.
Vietnam’s filing is still due December 31, 2025.
CSC Corptax GMT is ready right now to ensure you file timely.
What this means for you:
Türkiye has only released the Local Minimum Supplementary Corporate Tax Declaration through an
e-Declaration Test module so far. As a result, the tax year 2024 filing will be completed through
Türkiye’s portal.
As requirements take shape, CSC Corptax® will stay closely aligned with the guidance and will support clients in organizing and reviewing their QDMTT data.
What to do now:
The deadline extension doesn’t slow the pace of Pillar 2. Requirements continue to evolve, and major filings will converge across 2025 and 2026.
This is the moment to ensure your data is complete, consistent, and ready for notifications, QDMTTs, and the GIR as jurisdictions release additional guidance.
