XBRL FRC Taxonomies
The following versions of the FRC Taxonomies are available to download:
The 2019 Taxonomy suite Version 1.1.0 (2019) (zip file)
The 2018 Taxonomy suite Version 1.0.0 (2018) (zip file)
The 2014 Taxonomy suite Version 2.1.0 (2014) (zip file)
Each suite relates to the FRC’s Taxonomies: UK IFRS, FRS 101, FRS 102 and Charities and contains taxonomy documentation (supporting documents, key information sheets and release notes). Note that the 2014 suite does not contain a Charities taxonomy.
The 2019 Taxonomy suite
The 2019 taxonomy suite released on 1 October 2018 covers IFRS standards that have been endorsed since the 2018 taxonomy suite releases. The standards included are IFRS 9 Financial Instruments; IFRS 15 Revenue from Contracts with Customers and IFRS 16 Leases.
IFRS 15 and IFRS 9 are effective for annual periods beginning on or after 1 January 2018. IFRS 16 is effective for annual periods beginning on or after 1 January 2019. Early adoption of these standards is permitted.
This suite also reflects the amendments made to UK GAAP standards on 14 December 2017 because of the Triennial Review (“the Triennial Review amendments”), and are effective from years commencing on or after 1 January 2019. Early adoption of these amendments is permitted.
Who should use the 2019 suite?
IFRS reporters need to use this suite to be able to digitally report under the above standards. UK GAAP reporters applying the Triennial Review Amendments may also elect to use this suite to have access to the most up-to-date versions of the FRC Taxonomies and to comply with the HMRC requirement to fully tag.
HMRC will accept submissions using this suite from 22 February 2019. Companies House and the Irish Revenue Commissioners are expected to adopt the 2019 taxonomies suite in due course. Please refer to the HMRC Accepted Taxonomies page.
Micro and Small reporters should tag using only those parts of the FRS102 taxonomy which are relevant. FRS 101 reporters using the IFRS formats should tag using the extant IFRS taxonomy.
The suite has been designed with full tagging in mind. Accounts should be fully tagged.
The Charity Accounts Taxonomy may be used by all charities preparing accounts in accordance with the Charities FRS 102 SORP and is mandatory for large charities with income over £6.5m. (See below for more information on the Charity Accounts Taxonomy)
Supporting Material
Mapping documents detailing all the changes to the suite since the 2018 version and the standard to which the changes relate can be found:
Mapping: FRC 2019 Taxonomy Report - IFRS (October 2018) (Excel)
Mapping: FRC 2019 Taxonomy Report - FRS 101 (October 2018) (Excel)
Mapping: FRC 2019 Taxonomy Report FRS 102 (October 2018) (Excel)
Mapping: FRC 2019 Taxonomy Report - Charities (October 2018) (Excel)
The mapping documents are designed to enable software houses to easily identify the changes. Four colours are used with red denoting a deletion, green an addition, yellow a change to an existing line, and orange to indicate deprecated items.
Two new columns have been added to the start of each sheet to provide more information in relation to the change. The first column ‘Description of Change’ provides a brief but informative description of the nature of the changes. The second column ‘Ancestry Change’ indicates that a concept has moved with the current hierarchy.
Developer and Tagging guides are available in the section: Designs and Guides. The guides are applicable for all published versions of the taxonomies. A Design guide is also available which sets out the design principles behind the FRC Taxonomies. FRC Consistency Checks and Joint Filing Common Validation Checks are available in the section: Consistency Checks.
UK Taxonomy Guidance
The FRC’s 2019 taxonomies suite has adopted a system of deprecating certain XBRL concepts. Deprecated concepts will include a Deprecated Label and a Deprecated Date Label and, for convenience, include a string appended to the concept's Standard Label such as "(Deprecated 2019-01-01)".
The reason for using deprecated concepts for the 2019 suite of amendments, is because the amendments relate to IFRS standards, but they do not relate to UK GAAP standards. The FRC’s 2019 taxonomy suite contains a ‘core’ that is common to each of the taxonomies in the suite. As a result of the amendments to IFRS, a number of concepts in the ‘core’ taxonomy are now deprecated to indicate their use IS NOT permitted for entities reporting under IFRS, although they can continue to be used by those entities reporting under FRS 102 and insurance filers. Should a future review of FRS 102 align it more closely with IFRS, then some of these deprecated concepts may be removed from the ‘core’ to the extent the reporting requirements become aligned across the standards.
Technical Note
UK practice for marking a concept as "Deprecated" is to include a string appended to the concept's Standard Label in the form "(Deprecated 2019-01-01)". In addition, the concept is given a Deprecated Label[1] and a Deprecated Date Label[2].
The content of the Deprecated Label may describe the circumstances under which the concept has been deprecated and may suggest an alternative concept to use. The Deprecated Date Label provides the date of publication of the taxonomy to which the deprecation has been applied.
The date is for informational purposes only and does not affect validation.

Consultation and Feedback documents
The 2019 suite was subject to a consultation and a Feedback statement (PDF).
Whilst the consultation is now closed, Yeti is open for comments on any issues regarding the 2019 taxonomies suite. Evidence of issues which arise with use of the FRC taxonomies is of interest to the FRC and we encourage responses either via Yeti (https://uk-taxonomies-tdp.corefiling.com/yeti/resources/yeti-gwt/Yeti.jsp) or emailed to j.guest@frc.org.uk.
The 2018 Taxonomy suite
The 2018 taxonomy suite released on 18 December 2017 reflects the Triennial Review amendments made to UK GAAP Financial Reporting Standards on 14 December 2017. These amendments are effective for years commencing on or after 1 January 2019. Early adoption is permitted.
The suite reflects IFRS standards endorsed by the EU as of December 2017, except for IFRSs 9,15 and 16.
Who should use the 2018 suite?
UK GAAP reporters who have adopted the Triennial Review amendments may elect to use this suite. IFRS reporters may use this suite for financial reporting except where they are applying the newly endorsed standards IFRS 9, IFRS 15 and/or IFRS 16.
Micro and Small reporters should tag using only those parts of the FRS102 taxonomy which are relevant. FRS 101 reporters using the IFRS formats should tag using the extant IFRS taxonomy: Mapping: FRC 2018 Taxonomy Report - IFRS (Excel)
HMRC has adopted the 2018 taxonomy suite for filing of accounts and last updated their systems in April 2018. The taxonomies are mandatory for HMRC for accounts that are prepared under FRS 101, FRS 102 and EU-adopted IFRS.
The suite has been designed will full tagging in mind, so accounts must be fully tagged insofar as the taxonomy used contains appropriate XBRL tags. Please refer to the HMRC Accepted Taxonomies page.
The Charity Accounts Taxonomy may be used by all charities preparing accounts in accordance with the Charities FRS 102 SORP and is mandatory for large charities with income over £6.5m
Charity Accounts Taxonomy
An updated version of the Charity taxonomy was released by the FRC and the Charity Commission (CC) on 18 December 2017 for the electronic tagging of charity accounts to support the CC’s objectives of enhancing the quality and accessibility of financial reporting for Charities in the UK and Ireland. Those reporters not early-adopting the amended FRS 102 standard who wish to continue to report using the previous version of the charity taxonomies, may continue to do so. The iXBRL accounts tagging convention (Charity “taxonomy”) has been updated in line with the Charity SORP (FRS 102) and the FRC’s financial reporting standard FRS 102.
The taxonomy will be used when tagging charity accounts for electronic filing and for other analytical purposes. Electronic tagging helps users of financial information to extract relevant information from charity reports and analyse it more efficiently. (insert the following zip files)

Responses to the consultation
The 2014 Taxonomy Suite
Who should use the 2014 Taxonomy suite?
The 2014 Taxonomy suite should only be used for financial reporting to HMRC under UK GAAP if you have not yet adopted the Triennial Review amendments made to UK GAAP on 14 December 2017. If you have adopted these amendments, you should not be using this suite because in doing so you will not be able to comply with the HMRC requirement to fully tag. This taxonomy suite should not be used on or after 1 January 2019. Please refer to the HMRC Accepted Taxonomies page.
The 2014 Taxonomy suite can be used to report with to Companies House; who accept this suite.
