News types: Feedback Statement
Published: 5 March 2026
The Financial Reporting Council (FRC) has today published a feedback statement summarising responses to its discussion paper on proposed technical changes to the UK and Irish Digital Reporting Taxonomy Suite.
The discussion paper, published on 7 November 2025, invited feedback from stakeholders across the digital reporting ecosystem on a series of proposed architectural and technical changes aimed at improving the usability, scalability, and technical integrity of the taxonomies. The consultation closed on 11 January 2026.
The FRC received four detailed written responses to the discussion paper. In addition, the proposed changes were extensively discussed with the XBRL Technical Task Force, which comprises representatives from software houses and agencies operating within the UK digital reporting ecosystem, and through technical forums with software vendors operating across the UK and the Republic of Ireland.
The feedback statement summarises stakeholder views across the key areas of the discussion paper, including: replacing legacy data types with Extensible Enumerations to align with international standards; introducing XBRL formula linkbase to embed validation rules and improve data quality; expanding the use of typed dimensions to better support the reporting of complex entity structures; and the potential digitisation of Charities Receipts and Payments accounts.
Respondents were broadly supportive of the proposed changes, recognising the value of digital reporting and the importance of ensuring that taxonomy modelling is pragmatic, efficient, and supports the generation of high-quality, comparable data. Stakeholders consistently highlighted the importance of maintaining global comparability and aligning taxonomies with international XBRL specifications.
The FRC has confirmed that consultation responses will inform its ongoing strategic development of the Taxonomy project.
