From 1 January 2026, all medium and large companies in the Netherlands must file their annual accounts with the Chamber of Commerce (KvK) in iXBRL format. While small and micro-entities have already been filing via XBRL for years, this extension marks a significant shift for larger organisations.
What does SBR stand for in business?
Standard Business Reporting (SBR) is a government-initiated framework that standardises how businesses submit financial and regulatory information to public sector agencies. The term refers both to the broader policy initiative and to the specific technical implementation, which uses iXBRL (inline eXtensible Business Reporting Language) as its primary data format.
The Chamber of Commerce in the Netherlands introduced Standard Business Reporting (SBR) as a response to fragmented reporting requirements. Previously, companies submitted similar data to various agencies using incompatible forms, leading to high compliance costs and manual entry errors.
The SBR framework addresses this by establishing a common data standard. Businesses prepare their financial statements once using a standardised digital taxonomy, then submit to multiple agencies without re-entering information. Government systems process the data automatically, reducing processing times and improving data quality.
The technical foundation of SBR is XBRL. An extension of this is iXBRL, which offers companies greater flexibility. Unlike standard XBRL, which requires a rigid template, iXBRL allows companies to use their existing reports, convert them to HTML, and tag the data directly within their own layout. Understanding the distinction between XBRL and iXBRL filing formats clarifies why the inline approach was chosen – it preserves human readability while enabling machine processing.
Key reporting bodies for SBR
In the Netherlands, SBR enables reporting to multiple regulatory bodies through a single structured format:
- Tax and Customs Administration (Belastingdienst) – turnover tax returns, corporation tax returns, abbreviated corporation tax returns, reports concerning intracommunity performances, and income tax returns
- Central Statistics Office (CBS) – production statistics reports and investment statistics reports
- Chamber of Commerce (Kamer van Koophandel) – annual accounts including balance sheet, profit and loss account, and notes
- Banks – credit reports for loan applications and ongoing credit monitoring
This unified approach eliminates the need to reformat and re-enter the same financial data for each separate submission.
Who must comply with SBR?
SBR requirements have been in place for several years. However, effective 1 January 2026, this requirement extends to include medium and large companies. For these entities, iXBRL is the recommended, and in most cases, required format for filing with the KvK.
The annual accounts must be tagged according to the Dutch Taxonomy, which defines the specific data elements and technical structure of those tags. The Reporting Manual 2025, published by the SBR Programme Office, provides detailed guidance on taxonomy application and technical implementation.
For tax returns, SBR is the mandatory technical standard for system-to-system filing. While micro-entrepreneurs may use a portal, any business using accounting software or a tax intermediary must submit Corporate Income Tax (VPB) and VAT returns via the SBR/Digipoort system.
It is important to distinguish between different iXBRL reporting obligations. SBR in the Netherlands uses the Dutch Taxonomy. ESEF reporting uses the ESEF Taxonomy developed by ESMA. The MiCA regulation requires crypto-asset whitepapers to be submitted using the MiCA Taxonomy. These are distinct requirements with separate technical specifications, even though they all use iXBRL as the underlying format.
How does SBR work technically?
SBR relies on three core technical components: a standardised taxonomy, iXBRL tagging of financial statements, and validation and submission infrastructure.
The taxonomy is a structured dictionary that defines all reportable data elements, the relationships between them, and the rules governing their use. The Dutch Taxonomy specifies hundreds of financial statement line items, from revenue to specific balance sheet categories. Each concept has a unique identifier, definition, and technical properties such as data type and dimensional attributes.
Financial statements are prepared as iXBRL documents by embedding XBRL tags within HTML. When a company reports revenue of €1,200,000, the figure appears in a standard HTML table viewable in any browser. Simultaneously, it contains an embedded tag identifying the figure as “Revenue” according to the taxonomy concept, with reporting period, currency, and other contextual information.
Once prepared, the iXBRL document must be validated before submission. Validation software checks that all required concepts are tagged, data types are correct, mathematical relationships hold true, and the document conforms to the technical specification.
After validation, the file is submitted through the designated portal. The receiving agency’s systems extract the structured data and process it without manual intervention – the primary efficiency gain of SBR.
What software is needed for SBR compliance?
Organisations cannot prepare SBR-compliant documents using standard word processors or spreadsheets. Specialised software is required to embed XBRL tags according to the technical specification.
A common misconception is that SBR reporting is inherently time-consuming and complex. Appropriate software makes the process faster than manual form completion. Well-designed iXBRL tools automate tag applications, perform instant validation, and enable reuse of tagged data across multiple reporting obligations.
The choice of iXBRL software depends on several factors: volume of reports, complexity of financial statements, customisation required, and whether the organisation needs to support multiple reporting obligations such as both SBR and CSRD.
Key features to evaluate include support for the Dutch Taxonomy, built-in validation, ability to handle extensions for company-specific disclosures, user interface design, integration with existing accounting systems, and quality of vendor support.
Some organisations outsource SBR preparation to external accountants or corporate service providers. The provider prepares the iXBRL file, and the client reviews and approves before submission. This approach is common for smaller companies without in-house technical expertise.
How does SBR relate to other digital reporting requirements?
SBR is one of several iXBRL-based reporting obligations organisations may face. Understanding these relationships is important for compliance planning and software selection.
The European Single Electronic Format (ESEF) requires listed companies in the EU to prepare annual financial reports in iXBRL format. ESEF uses the ESEF Taxonomy based on IFRS, while SBR uses the Dutch Taxonomy accommodating both Dutch GAAP and IFRS. A listed Dutch company may need to prepare both ESEF-compliant consolidated accounts and SBR-compliant entity accounts.
The Corporate Sustainability Reporting Directive (CSRD) extends digital structured reporting to sustainability information. The CSRD implementation timeline phases in requirements across different company sizes from 2025. Sustainability reports will eventually be required in a structured format similar to iXBRL.
The Markets in Crypto-Assets regulation (MiCA) introduces iXBRL requirements for crypto-asset service providers operating in the EU.
Organisations subject to multiple requirements should consider software platforms that handle ESEF, SBR, MiCA, and CSRD within a single application – simplifying training, reducing vendor relationships, and offering cost efficiencies.

Frequently Asked Questions (FAQs) about SBR
- What does SBR stand for in business?
SBR stands for Standard Business Reporting. It is a government-initiated framework that standardises how businesses submit financial and regulatory information to public sector agencies using structured digital formats, primarily iXBRL. The initiative reduces administrative burden by enabling companies to prepare financial data once and submit to multiple government bodies without re-entering information.
- Is SBR mandatory in the Netherlands?
From 1 January 2026, SBR is mandatory for annual accounts filed with the Dutch Chamber of Commerce. All limited companies (BVs and NVs) and foreign legal entities with a Dutch branch must file in iXBRL format using the Dutch Taxonomy. For tax returns, SBR remains optional.
- What is the difference between SBR and ESEF?
SBR and ESEF are both iXBRL-based frameworks but serve different purposes. SBR is a Dutch national initiative for filing statutory accounts with the Chamber of Commerce using the Dutch Taxonomy. ESEF is an EU-wide regulation requiring listed companies to prepare consolidated annual reports using the ESEF Taxonomy based on IFRS. Dutch listed companies may need to comply with both.
- What software do I need for SBR compliance?
You need specialised iXBRL software supporting the Dutch Taxonomy. Options include dedicated iXBRL tagging tools, integrated accounting systems with built-in iXBRL export, or outsourcing to a service provider. Key features include taxonomy support, validation functionality, and ease of use.
- How long does it take to prepare an SBR filing?
Initial implementations require more time for taxonomy mapping, staff training, and process adjustments. Once established, subsequent filings are considerably faster than manual form completion. Many organisations find that well-designed iXBRL tools reduce overall preparation time compared to traditional methods.
- Can I use the same software for SBR and ESEF?
Some XBRL platforms support multiple taxonomies within a single application. If subject to both SBR and ESEF requirements, selecting software that handles both simplifies training and may offer cost efficiencies. Verify your chosen software explicitly supports both the Dutch Taxonomy and the ESEF Taxonomy.
