Dutch SBR approaches 60 million XBRL submissions
XBRL Netherlands Chair Sander ‘t Hoen, of SureSync B.V., had a statistical fact that caught our eye at the Digital Reporting Europe event this week. Standard Business Reporting (SBR) in the Netherlands processed nearly 60 million messages in 2025, continuing a run of uninterrupted year-on-year growth. The figure is up from 42 million in 2018, representing growth of more than 40% over seven years.
SBR is the primary channel through which Dutch businesses submit annual reports and tax declarations digitally through a conformed filing process, using the XBRL standard. Annual reports flow to three receiving bodies: the Chamber of Commerce (KVK), DUO (the executive agency of the Ministry of Education), and the Authority of Housing Associations (AW). On the tax side, the system handles income tax, corporate tax, VAT, and payroll tax declarations for the Dutch Tax and Customs Administration.
By standardising the structure and format of these submissions, SBR reduces the administrative overhead for businesses and ensures that receiving agencies can process data reliably and at scale. The volume figures reflect the breadth of that coverage: the system serves businesses of all sizes across a wide range of filing obligations. Those include innovative disclosure types like property values and statements from educational institutions.
The Netherlands has been one of the longest-running national implementations of structured business reporting, and the continued growth in message volumes underlines the value of a stable, well-supported infrastructure for digital financial reporting. Sander’s presentation (on Educational institutions’ shift to Inline XBRL filing) will be up on the event website soon.
