IASB Proposes IFRS Accounting Taxonomy 2025 Updates for IFRS 20, IAS 21 and IFRS 19
IASB Proposes IFRS Accounting Taxonomy 2025 Updates for IFRS 20, IAS 21 and IFRS 19
The International Accounting Standards Board has proposed updates to the IFRS Accounting Taxonomy 2025 to support the digital reporting of information prepared under IFRS 20, amendments to IAS 21 and amendments to IFRS 19. Stakeholders can comment on the proposed taxonomy update until 14 September 2026.
IASB Publishes Proposed Update to IFRS Accounting Taxonomy 2025
The International Accounting Standards Board (IASB) has published IFRS Accounting Taxonomy 2025—Proposed Update 2, introducing proposed taxonomy changes for three recently issued or amended IFRS Accounting Standards.
The proposals are intended to make information prepared under these requirements digitally accessible and easier for investors, regulators and other users to identify, extract and compare.
The IASB is seeking feedback from stakeholders involved in preparing, tagging or using digital financial reports. The consultation remains open until 14 September 2026.
What Does the Proposed IFRS Accounting Taxonomy Update Cover?
The proposed update introduces taxonomy changes associated with:
1.IFRS 20 Regulatory Assets and Regulatory Liabilities
IFRS 20 was issued in May 2026 and establishes accounting requirements for regulatory assets and regulatory liabilities.
The proposed taxonomy update is designed to enable companies to digitally tag information reported under IFRS 20, helping users identify and analyse disclosures related to rate-regulated activities.
2.Amendments to IAS 21
The taxonomy proposals also reflect Translation to a Hyperinflationary Presentation Currency, issued in November 2025 as amendments to IAS 21 The Effects of Changes in Foreign Exchange Rates.
The amendments address the translation of financial information when an entity’s presentation currency is the currency of a hyperinflationary economy. The proposed taxonomy changes would support the structured digital reporting of information arising from these requirements.
3.Amendments to IFRS 19
The update also covers amendments to IFRS 19 Subsidiaries without Public Accountability: Disclosures, issued in August 2025.
IFRS 19 allows eligible subsidiaries to apply IFRS Accounting Standards with reduced disclosure requirements. The proposed taxonomy changes would help eligible subsidiaries digitally tag information reported under the amended disclosure requirements.

Why Is the IFRS Accounting Taxonomy Update Important?
An accounting standard defines what companies must recognize, measure, present and disclose. An accounting taxonomy translates those reporting requirements into structured digital elements that can be used in XBRL and Inline XBRL reports.
The proposed update is therefore an important step in making the new and amended accounting requirements digitally reportable.
Once finalized, the taxonomy additions may affect:
1.the elements available for tagging IFRS financial statements;
2.the selection of appropriate taxonomy concepts;
3.the use of company-specific extensions;
4.anchoring and presentation relationships;
5.calculation and validation processes;
6.taxonomy-version management; and
7.review procedures for digital financial reports.
Preparers and software providers will need to assess the final taxonomy changes before incorporating them into their reporting processes.
What Should IFRS Digital Reporting Teams Do?
Although the taxonomy update is currently a proposal, organizations that may be affected should begin reviewing its potential implications.
Reporting teams should:
1.Identify whether IFRS 20 or the relevant amendments to IAS 21 and IFRS 19 apply to their organization.
2.Review the proposed taxonomy elements and supporting relationships.
3.Compare the proposed elements with current reporting and tagging practices.
4.Assess whether existing company-specific extensions may be replaced by standard taxonomy elements.
5.Coordinate accounting, financial-reporting and XBRL implementation activities.
6.Consider submitting feedback to the IASB before the consultation closes.
Early assessment can help organizations prepare for taxonomy implementation and reduce late-stage tagging or validation issues.
Is the IFRS Accounting Taxonomy Update Final?
No. The IASB has published the changes as a proposed update to the IFRS Accounting Taxonomy 2025.
The proposals may be revised after the IASB considers stakeholder feedback. Companies should therefore avoid treating the proposed elements as final production requirements.
The deadline for submitting comments is 14 September 2026.
