The European Securities and Markets Authority has published the 2025 European Single Electronic Format (ESEF) XBRL taxonomy files and an updated ESEF Conformance Suite to support issuers and software vendors preparing 2026 IFRS consolidated financial statements in the latest ESEF format. The 2025 taxonomy incorporates IFRS 18 Presentation and Disclosure in Financial Statements, which is effective from 1 January 2027 with early application permitted. It provides two entry points so issuers can report under either IAS 1 or IFRS 18. ESMA also indicated it does not plan to amend the ESEF regulatory technical standards or taxonomy in 2026, aligning with the IFRS Foundation’s decision not to issue a 2026 IFRS Accounting Taxonomy update and giving firms additional implementation time. ESMA encouraged issuers and software providers to consult the IFRS Foundation’s guidance on using the 2025 IFRS Accounting Taxonomy for 2026 reporting periods and invited feedback and questions on the 2025 ESEF taxonomy and conformance suite.
