From 2026, all large and medium-sized companies in the Netherlands will be required to file their annual reports with the Kamer van Koophandel (KVK) in iXBRL format under Standard Business Reporting (SBR) rules. That means over 8,000 Dutch companies need to act, and accountancy and audit firms will play a central role in making it happen.
Choosing the right SBR software for KVK filing is one of the most important decisions for smooth reporting experience. The wrong tool creates bottlenecks during peak periods, puts pressure on senior staff, and risks missing submission deadlines.
This guide reviews the five best SBR software solutions available in 2026, evaluated on ease of use, onboarding speed, certification, multi-client scalability, and pricing transparency. Whether you are a firm that plans to do tagging in-house or a corporate service provider, you will find a clear picture of which platform fits your needs.
What to Look for in SBR Software for KVK Filing
Before diving into the comparison, here are the criteria that matter most for firms preparing to offer SBR tagging services at scale:
- Onboarding speed – How quickly can a new staff member start tagging reports accurately?
- XBRL certification – Only certified software guarantees valid, KVK-compliant iXBRL output.
- Multi-entity management – Firms handling dozens of entities need a centralised workspace, not a separate tool per client.
- AI-assisted tagging – Smart tag suggestions reduce manual effort, speed up delivery, and reduce errors.
- Auditor collaboration – The ability to give auditors direct access inside the platform removes costly back-and-forth files.
- Support during peak periods – Submission windows are tight. Responsive support during crunch time is a real differentiator.
- Pricing model – Per-client licensing is easier to manage and pass through to clients than user-based or report-based pricing.

SBR Software Solutions - FAQs
- What is SBR software?
SBR (Standard Business Reporting) software enables companies to produce annual reports in iXBRL format for filing with the Kamer van Koophandel (KVK). From 2026, this is mandatory for all large and medium-sized Dutch companies. The software handles conversion of financial documents into structured iXBRL packages and validates them against the SBR taxonomy before submission.
- Which companies need to file in iXBRL format under SBR?
All large and medium-sized companies registered in the Netherlands must file their annual reports in iXBRL format from the 2026 reporting year onwards. This affects an estimated 8,000+ businesses – a significant expansion from the approximately 168 listed companies previously required to file under ESEF.
- How is SBR different from ESEF?
ESEF (European Single Electronic Format) applies to listed companies filing with securities regulators across the EU. SBR is the Dutch national standard and applies to a much broader group of companies – including non-listed large and medium-sized entities – filing their annual accounts with the KVK. For more background, see: What is ESEF?
- What is iXBRL tagging?
iXBRL (Inline XBRL) is the technical format used for structured financial reporting. Tagging is the process of marking up financial statements with accounting definitions from a taxonomy – a structured dictionary of financial concepts. The result is a document that is both human-readable and machine-processable. For a plain-language explanation, see: What is XBRL?
- Can accountancy firms offer SBR tagging as a service?
Yes – and many are already preparing to do so. Firms that already provide ESEF tagging services are well-positioned to extend this to SBR. For firms new to iXBRL tagging, platforms like CFOUR Comply are designed to make this commercially viable, with per-client pricing and short onboarding times.
- How long does it take to tag a report using SBR software?
With CFOUR Comply, most first-time users complete tagging within one day for a standard annual report. For repeat clients using roll-forward functionality, the time is even shorter.
- Which companies need to file in iXBRL format under SBR?
All large and medium-sized companies registered in the Netherlands must file their annual reports in iXBRL format from the 2026 reporting year onwards. This affects an estimated 8,000+ businesses – a significant expansion from the approximately 168 listed companies previously required to file under ESEF.
