ESEF Tagging, Done for you

Outsourced ESEF iXBRL tagging and filing for listed companies: accurate, ESMA-compliant and delivered on your timeline

ESEF Reporting, Simplified

ESMA compliant ESEF iXBRL reporting made easy

What ESEF Tagging Involves

The European Single Electronic Format (ESEF) requires issuers with securities admitted to trading on EU and EEA regulated markets to publish their annual financial reports in XHTML. Where the report contains IFRS consolidated financial statements, those statements must be tagged in Inline XBRL (iXBRL) using the ESEF taxonomy.

A compliant ESEF filing typically requires:

  • Conversion of the annual report into a single XHTML file that preserves its visual design
  • Detailed tagging of the primary financial statements
  • Block tagging of the notes to the financial statements
  • Extension elements, anchored to the closest elements in the base taxonomy, where no suitable standard element exists
  • Validation against the ESEF Regulatory Technical Standards and ESMA’s Reporting Manual
  • Packaging of the report as an ESEF-compliant reporting package

Our ESEF Tagging and Filing Services

Full ESEF Conversion and Tagging

We take your final annual report as PDF or Word and deliver a validated, filing-ready ESEF reporting package. The design matches your printed report.

Block Tagging of the Notes

Our team applies text-block tags to each note and accounting policy, then reviews them for consistency with your primary statements.

Validation and Quality Review

Every file goes through automated validation and a manual review by a second iXBRL specialist before delivery.

Roll-Forward for Repeat Filers

For returning clients, we roll forward your previous year’s tagging. This keeps your tag choices consistent year on year and shortens turnaround.

What European regulatory reporting solutions does DataTracks offer?

DataTracks provides software and services for KVK and ESEF reporting, alongside solutions for AIFMD Annex IV, COREP/FINREP, Solvency II, FATCA/CRS, CbCR, and other regulatory requirements. Our team helps you select the right solution for your reporting obligations. 

DataTracks helps prepare annual accounts for digital filing with the Netherlands Chamber of Commerce. Our support includes XBRL/iXBRL conversion, taxonomy mapping, tagging, and validation to prepare filing-ready reports. 

ESEF is the European Single Electronic Format for annual financial reports of issuers subject to the EU Transparency Directive’s reporting requirements. Reports must be prepared in XHTML, with Inline XBRL tagging applied to IFRS consolidated financial statements. 

No. KVK reporting concerns statutory annual accounts filed with the Netherlands Chamber of Commerce, while ESEF concerns annual financial reporting by issuers within its scope. Although both can use XBRL-based formats, their taxonomies, report contents, and submission requirements differ. An ESEF report should not automatically be treated as a KVK-ready filing. 

AIFMD Annex IV reporting requires alternative investment fund managers within scope to report information about their funds to the relevant national competent authorities. This includes information on investments, exposures, leverage, liquidity, and risk. 

Alongside KVK and ESEF, DataTracks offers solutions for AIFMD Annex IV, COREP/FINREP, Solvency II, MiCA, FATCA/CRS, and CbCR. Fund managers, and financial institutions can choose support suited to their applicable reporting obligations.
