FRC announces updates to conventions for electronic tagging of accounts

23 December 2015


The Financial Reporting Council (FRC) has published additional tags to the XBRL electronic tagging conventions (taxonomies) last published in September 2014 to enable up-to-date electronic reporting to be in place in 2016.

Taxonomies enable accounts to be filed electronically and for users of information in corporate reports to extract data and analyse it more effectively.

The latest updates reflect 2015 changes in UK GAAP and company law and include electronic tags to indicate the nature of the entity and the accounting standards applied. HMRC and Companies House will be updating their guidance to incorporate the amended taxonomies.


Guidance for amendments to the FRC 2014 Taxonomies

The FRC has made amendments to the suite of taxonomies issued in September 2014 by implementing additional tags to enable:

  • Micro preparers to tag using only those parts of the FRS102 taxonomy which are relevant

  • Small preparers using FRS102 to do likewise

  • FRS 101 preparers using the IFRS formats to tag using the extant IFRS taxonomy

  • The introduction of an Abridged Accounts indicator

  • To insert 150 new tags over and above the 50 tags which already exist in the taxonomies for the reporting of subsidiaries. Further, to introduce a tag to indicate companies which have more than 200 subsidiaries.

The amended taxonomies are at
