KVK Digital Reporting Mandate 2026: Get Ready for iXBRL Filing in the Netherlands
KVK Digital Reporting Mandate 2026: Get Ready for iXBRL Filing in the Netherlands
About the Regulation
Starting January 1, 2026, the Netherlands Chamber of Commerce (Kamer van Koophandel or KVK) will require all registered companies to file their annual accounts electronically. This change stems from an amendment to the Electronic Filing Trade Register Decree, aligning with the EU’s move toward structured digital reporting under the Corporate Sustainability Reporting Directive (CSRD).
The goal is clear: greater transparency, improved efficiency, and higher data quality in financial and sustainability reporting across Europe.
Who Is Affected
The mandate applies to all registered companies with KVK – particularly large and medium-sized private subsidiaries – that must now prepare and file reports in Inline XBRL (iXBRL) format as a Report Package. Each submission must include:
- Financial Statements (individual and consolidated) and Notes
- Management Report
prepared under NL-GAAP or IFRS.
Important: Filing by post or email will no longer be accepted. Reports must be uploaded electronically via the KVK portal or certified software.

| Feature | XBRL | iXBRL |

What is ESEF Reporting?
ESEF stands for European Single Electronic Format. It is a new reporting format for public companies in the European Union that requires them to publish their annual financial reports in a single, electronic format. ESEF is designed to improve the transparency and comparability of financial reporting across the EU.
Which companies need to comply with the ESEF tagging mandate?
ESEF applies to all public companies in the EU and UK that are listed on a regulated market. Consolidated IFRS accounts must be tagged using the ESEF taxonomy, but non-consolidated reports only need to be submitted in XHTML format without tagging.
What are the requirements for preparing an ESEF iXBRL report?
ESEF iXBRL reports must be prepared in XHTML format, with IFRS consolidated financial statements tagged using XBRL. The XBRL tags must be embedded in the XHTML document using Inline XBRL technology.
Who is affected by the ESEF reporting requirement?
The ESEF Reporting Requirements affect all issuers whose securities are admitted to trading on regulated markets within the European Union (EU), as well as all issuers who are required to prepare consolidated financial statements in accordance with International Financial Reporting Standards (IFRS), unless they are small and micro enterprises (SMEs) and their securities are not admitted to trading on a regulated market.
