What we do
ESEF reports (iXBRL)

Since 2021, companies whose securities are traded on European regulated markets are required to publish their annual financial statements following the ESEF regulation.

We offer a hassle-free service to prepare an annual report that meets the ESEF requirements. We already have a ready-made solution that allows you to get your validated XHTML report without waste of time and effort and minimum additional workload for your team.

What is ESEF, iXBRL, and XTHML?


The European Single Electronic Format is the electronic reporting format in which issuers on EU regulated markets shall prepare their annual financial reports from January 1 2020. In 2013, the Transparency Directive (TD) that sets rules on harmonisation of transparency requirements of issuers, was amended to include a requirement for issuers to prepare their annual financial reports in a single electronic reporting format (ESEF). That means the new XHTML + iXBRL format is applied to the reporting periods beginning on or after January 1, 2022.


Extensible HyperText Markup Language. XHTML is human-readable.

iXBRL (Inline XBRL)

Extensible Business Reporting Language. XBRL International sets the specification. XBRL is computer-readable. The new format allows specialised information systems to process financial statements and company data automatically. Human readable and computer-readable (XHTML+XBRL tags).


Pre-defined list of electronic tags, labels, descriptions, and definitions.

Standards (RTS) on ESEF
All annual financial reports shall be prepared in XHMTL format which can be opened with standard web browsers.
Where the annual financial report contains IFRS consolidated financial statements, these shall be labelled with XBRL ‘tags’ which makes the labelled disclosures structured and machine-readable.
The XBRL ‘tags’ shall be embedded in the XHTML document using the Inline XBRL technology which allows to encapsulate the XBRL tags in the XHTML document within a single document set.
The IFRS consolidated primary financial statements (income statement, balance sheet, etc.) shall be marked up in detail, whereas the notes to these financial statements need to be marked up by applying mark-ups for whole sections of the notes (block tagging).
The taxonomy to be used is the ESEF Taxonomy (IFRS taxonomy plus some additions).
