Block Tagging 101 for All ESEF iXBRL Filers

About the Mandate

The ESMA ESEF mandate is divided into phases. In phase 1 of the mandate, issuers must ensure that primary financial statements have been tagged according to the latest ESMA taxonomy. Phase 2 entails tagging all notes to their annual financial statements as a block tag along with the tagging of financial statements.

Phase 2 is applicable from 1st January 2022 i.e. for annual reports ending 31st December 2022. In phase 2 of the mandate, every note within the annual financial statements will be block tagged with XBRL tags applies to it. Users will be able to view the XBRL tags and properties once they click on the notes.

8. The iXBRL Viewer

The last step is to generate an iXBRL Viewer file and conduct a final review of tags on the XHTML document.

  • For viewing the iXBRL files, one needs access to an iXBRL viewer. ESMA does not provide any viewer for the filers. However, IRIS has developed an iXBRL viewer for the issuers to see how their iXBRL document will look before submitting it to the national regulator.
  • For accessing the iXBRL viewer, the user needs to click on Generate Output. Once the document is generated, click on the “Generate External Viewer Link”. Once you click on it, a popup window will open with the link. You can simply copy this link, open a new browser window and paste the copied link.
