Current FRC Taxonomy Suites

Preparers must select the specific taxonomy version that models the underlying accounting standards used in the preparation of their accounts. Using older taxonomy versions that lack the necessary tags to digitally represent required disclosures will result in incomplete tagging. The specific taxonomy versions that preparers can use, including dates for adoption, are governed by the requirements and guidance of the relevant data collectors, such as HMRC, Companies House, and Irish Revenue.

Versions of the full suite of FRC taxonomies for 2026 and 2025 were released on 18 November 2025 and 18 October 2024 respectively. Historical versions of the taxonomies can be found here.

The taxonomies should be implemented, used and understood alongside the Documentation and Guidance.
