Practical implications
MNE groups parented in Türkiye are subject to the IIR for fiscal years beginning on or after 2024-01-01. Where a subsidiary's jurisdictional effective tax rate (ETR) falls below 15%, top-up tax is computed and paid in Türkiye (as the jurisdiction of the parent entities), and the group must also file the GloBE Information Return (GIR).
MNE groups with constituent entities in Türkiye are subject to Türkiye's QDMTT for fiscal years beginning on or after 2024-01-01. Where the conditions of the QDMTT Safe Harbour are met, the IIR/UTPR computation at the parent jurisdictions may be exempted, reducing the burden of dual computation.
