The South Korea Financial Supervisory Service announced that Kospi- and Kosdaq-listed financial companies with assets exceeding KRW 10 trillion have completed the first mandatory application of XBRL to financial statement notes, submitting their 2025 semi-annual reports with XBRL-applied notes by the August 14, 2025 filing deadline. The phase-in will expand next year to listed financial companies with assets above KRW 2 trillion, which will be required to file 2026 semi-annual reports with XBRL-applied notes by August 2026. A further expansion is scheduled for the 2027 semi-annual reporting cycle, when the remaining listed financial companies will become subject to the requirement. The FSS also noted that listed non-financial firms began filing XBRL-applied notes with 2023 annual reports and that the mandatory scope has since widened to include companies with KRW 500 billion to KRW 2 trillion in assets. As coverage expands, the FSS plans to work with relevant institutions to support companies’ submissions.
