XBRL FRC Taxonomies
News and Updates
UKSEF 2022 v2.0.0
The FRC has today issued UKSEF 2022 v2.0.0. This can be downloaded from this page.
UKSEF 2022 v2.0.0 includes the most recent, 2021 version of the ESEF taxonomy, as previously communicated in the v.1.0.0 October release. This is the only change between UKSEF 2022 v.2.0.0 and v.1.0.0.
It is anticipated that Companies House and FCA will issue forthcoming guidance on who can use this version when they have completed their due processes. For those wanting to access UKSEF 2022 v.1.0.0, it will be available on Yeti in the interim.
The 2022 suite of FRC Taxonomies has been issued on 8 October 2021.
The suite is updated for all FRC taxonomies. The amendments are summarized as follows, but for more detail please refer to the Design and Guides sections of this page. Key information documents are produced for all the taxonomies.
Key changes to the 2022 suite
The SECR taxonomy containing the TCFD disclosures has been incorporated into the main body of the FRC suite, as requested by software houses to facilitate the possibility of incorporating SECR tagging in products for tagging for accounting, so that more entities can be encouraged to take up supplying this information digitally. All items have migrated into the ‘direp’ (Directors’ Report) namespace when imported into the FRC suite.
The SECR and Task Force on Climate-related Financial Disclosures (TCFD) tags are now found in all the Directors’ Report section of the FRC Taxonomies (except for the Irish extensions and UKSEF).
With a view to embracing the ability to tag more detailed TCFD disclosures, even though they are not mandatory, the SECR Taxonomy has had its TCFD disclosures augmented to reflect expected enhanced disclosures from companies eager to provide information to investors. The original four reporting concepts have been made into headings with the greater detail contained in child tags relating to the headings.
The UKSEF imports the most up-to-date version of the ESEF and can be used with tags from the rest of the FRC taxonomies suite (including tags for the Directors Report, SECR and TCFD disclosures) for UK reporting purposes to Companies House and FCA. It is a UK version of the ESEF Taxonomy and overseas entities wishing to file with Companies House need to use the UKSEF to file, since it makes available the extra tags needed to file in the UK. Companies filing to the FCA can also use the UKSEF (also see the FRC and FCA joint letter to CEOs on structured reporting). A UKSEF guide for taggers and developers is available. The guide provides helpful guidance in relation to developing products for filing in the UK with the UKSEF and for those tagging with the UKSEF. This guide is necessary, since the ESEF rules and guidance are not aimed at UK filers and taggers.
The 2022 version of the UKSEF is more flexible and interchangeable with the other taxonomies in the FRC suite and, a different architecture allows for any future changes that may need to be made to the UKSEF, depending on future UK legislative changes and requirements.
The FRC taxonomies now support a Welsh label linkbase, to enable those that wish to browse the taxonomies and/or report in the Welsh language to be able to do so.
HMRC’s Detailed Profit & Loss (DPL) taxonomy extension is now part of the Directors’ Report.
- The DPL has been incorporated as a section within each of the current entry points, not separately as its own entry point.
- An additional concept has been added (for the UK only) for declaring that one has included a DPL statement.
Digitally enabling Gender Pay Gap reporting
Tags for Gender Pay Gap reporting have been included in the Directors Report for those who wish to tag these concepts.
Digital enabling of Academy reporting
The charitable status of Academy Trusts is that they are charitable companies but are exempt from registration with CCEW. The Department for Education (DfE) is Principal Regulator.
Academies report as charities under the Charities SORP (FRS102), and the Charity Commission is supportive of a tag for Academies to be inserted in the Charity Accounts Taxonomy to enable Academies to be able to digitally report.
An ‘Academy trust’ is the member name for Legal Form of Entity dimension and it has been placed high up in the Charities hierarchy so that it is obvious to an Academy to select the tag.
Who should use this suite?
The 2022 suite represents the most up-to-date version of the FRC Taxonomies and as such should be used to comply with HMRC requirements to fully tag. The suite has been designed with full tagging in mind. Accounts should be fully tagged, except for consolidated UKSEF data where regulations permit minimum tagging. Filers to HMRC and Companies House should use the most-up-to-date version where possible.
It is expected that Companies House will have enabled this suite by 1 April 2022 and the FCA will have enabled the suite by 31 December 2021. 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 filing with HMRC.
Mapping documents detailing all the changes to the suite since the 2021 version (2019 in the case of the Irish extensions) and the standard to which the changes relate can be found below:

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 within the current hierarchy.
Developer and Tagging guides are available in the section: Design and Guides. The guides are applicable for all published versions of the FRC taxonomies. A UKSEF guide is also available, as is a Design guide 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.
Irish Extension Taxonomy
An Irish extension of the 2022 taxonomy suite was released by the FRC on 8 October 2021 for the electronic tagging of Irish accounts to support the Irish Revenue Commissioners’ requirement for iXBRL financial statements as part of the Corporation Tax return. Further information on the Irish Extension Taxonomy, including older versions, can be found in the ‘XBRL Taxonomies Irish Extension’ section below.

Charity Accounts Taxonomy
An updated version of the Charity taxonomy was released by the FRC and the Charity Commission (CCEW) on 8 October 2021 for the electronic tagging of charity accounts to support the CCEW objectives of enhancing the quality and accessibility of financial reporting for Charities in the UK and Northern 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 Charities 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.

Key changes to the 2022 suite

Key changes to the 2021 suite
As part of continued efforts to increase digital enablement of accounts, we have enabled revised accounts. Disruption arising from the COVID pandemic has increased the need for this facility and highlighted the extent of the benefit that this will bring.
Covid Issues: additional income-related tags to cover the Coronavirus Jobs Retention Scheme (CJRS) and other Covid-related grants have been added.
Off Payroll Working: additional tags have been added to cover revenue from off payroll working and off payroll working expenses. These new tags have been added for all entry-points (FRS 101, FRS 102, UK IFRS and Charities).
Pay Ratio Regulations: The Statutory Instrument ‘The Companies (Miscellaneous Reporting) Regulations 2018’ sets out requirements for the reporting of pay ratio information in the Directors’ Remuneration Report. All entry-points have been amended to cover these requirements.
SECR Reporting: The SECR Taxonomy introduced in 2019 supersedes the greenhouse gas emissions reporting items present in the Directors’ Report. These tags have been removed (not deprecated, to avoid confusion with the SECR reporting requirements).
In addition, SECR reporting is an additional requirement for (large) companies who may choose to report using UK SEF. Consequently, the SECR taxonomy has been incorporated into the UKSEF taxonomy extension for the convenience of filers. This avoids the complication of additional combined entry-points.
Who should use this suite?
The 2021 suite represents the penultimate version of the FRC Taxonomies and as such can be used to comply with HMRC requirements to fully tag. The suite has been designed with full tagging in mind. Accounts should be fully tagged, except for consolidated UKSEF data where regulations permit minimum tagging. Filers to Companies House should use the most up-to-date version (2022 suite) where possible. Companies House and HMRC enabled the suite in July 2021.
The 2019 Taxonomy suite Version 1.1.0 (2019)
The 2018 Taxonomy suite Version 1.0.0 (2018)
The 2014 Taxonomy suite Version 2.1.0 (2014)
The 2019 SECR Taxonomy Version 1.0.0 (2019)
The 2019 Taxonomy suite
The suite was been designed with full tagging in mind. Accounts should be fully tagged.
Who should use the 2019 suite?
This suite does not form part of the current version of the FRC taxonomies in use and as such should only be used for reporting for historical accounts. If this suite is used for current reporting full tagging will not be possible and reporting will not be aligned with current HMRC and Companies House reporting requirements. Please refer to the HMRC Accepted Taxonomies
page and Companies House Accepted Taxonomies
The 2014 Taxonomy Suite
Entities should not be using this suite because in doing so you will not be able to comply with the HMRC requirement to fully tag. Companies House do not accept current submissions using this suite. This taxonomy suite should not be used on or after 1 January 2019. Please refer to the HMRC Accepted Taxonomies
page and Companies House Accepted Taxonomies
