Be ESEF compliant without overthinking it

Upload your annual report in PDF format, tag the report with a taxonomy of your choice, and download the generated ESEF report ready to be published

How will ESEF affect you?

As of 2020, the European Securities Markets and Authorities (ESMA) issued the ESEF standard which requires all issuers on EU regulated markets to prepare and file annual consolidated financial reports in Inline XBRL (iXBRL) format.

Due to the difficulties posted by the pandemic on both issuers and auditors, the ESEF requirements were postponed in most countries in Europe, by one year till 2021. This means that all annual financial reports beginning on or after 1st January 2021 must be submitted in iXBRL format to comply with the ESEF standard.

This means that if your company has securities listed on any EU stock exchange, you must comply with the ESEF standard.


All companies listed in EU, EEA and UK regulated markets.


For all annual reports for fiscal years beginning 01/01/2021.


Convert your annual report to electronic iXBRL/XHTML format using specialized software.
