Seamless KVK Reporting
From conversion to submission, we simplify your Dutch Chamber of Commerce iXBRL filings
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.
XBRL vs. iXBRL - Understanding the Difference
| Feature | XBRL | iXBRL |
| Standardisation | High and Rigid | Flexible, supports taxonomy extensions |
| Visual Design | Minimal | Retains original layout and design |
| Regulator Acceptance | Accepted | Recommended by regulators |
Why choose iXBRL?
- Reports are easier to review and analyze
- Supports embedded tags for consistency
- Enables extensions for local compliance
- Ensures long-term compatibility and transparency

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.
How does DataTracks support Dutch KVK reporting?
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.
What is ESEF reporting, and which companies does it apply to?
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.
Are KVK and ESEF reporting requirements the same?
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.
What is AIFMD Annex IV reporting?
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.
What other regulatory reporting solutions does DataTracks offer in the EU?
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.
