Starting next year, thousands of Dutch companies will face a new obligation from the Kamer van Koophandel (KvK):
companies classified as “Groot” (large) will need to file their annual reports in (inline) XBRL format.
This is a significant step in the ongoing digitization of financial reporting in the Netherlands.
The new regulation requires large private companies (grote rechtspersonen) to submit their annual accounts digitally in XBRL to the KvK.
This means:
• No more PDF-only filings – XBRL will be the single legal format.
• Structured, machine-readable data – ensuring better transparency and easier analysis by regulators, investors, and other stakeholders.
• Compliance deadlines remain similar to current reporting schedules, but the format and process change significantly.
For many companies, this represents more than just a technical challenge.
It affects how financial statements are prepared, reviewed, and published.
Moving from traditional reporting to XBRL can feel overwhelming:
• Complex formatting – ensuring your numbers and notes are correctly tagged.
• Multiple outputs – management and stakeholders still want a well-designed PDF, while the KvK requires Inline XBRL.
• Last-minute changes – financial reporting rarely goes 100% according to plan, and final adjustments often need to be made under tight deadlines.
Without the right tools, this can lead to stress, version-control issues, and costly delays.
