Local adoption of IFRS S1 / S2 (ISSB Standards)
Türkiye incorporated IFRS S1 and S2 fully into Turkish law as TSRS 1 and TSRS 2 on 29 December 2023, with mandatory application from fiscal year 2024 for listed entities, banks and other entities above size thresholds. KGK has since raised the size thresholds, removed portfolio management companies from scope, extended first-year transition reliefs for 2024 first-time reporters, and adopted the ISSB's greenhouse gas disclosure amendments to IFRS S2 as TSRS 2 amendments effective 2027.

- Effective date
- Fiscal periods starting on or after 1 January 2024; revised thresholds from periods starting on or after 1 January 2025; TSRS 2 GHG amendments from periods starting on or after 1 January 2027 (early application permitted)
