Choosing iXBRL software or a service for KVK filing
By XBRTags Netherlands | Information checked 6 November 2026
Choosing a KVK filing provider means deciding who will prepare the report, check the tags and confirm that the filing has completed. Software gives your team tools to do the work. A managed service can take on agreed preparation and submission tasks. In either case, the responsibilities should be clear before you commit.
Use these seven questions when comparing proposals. Ask vendors to demonstrate their answers using a sample report similar to yours.
1 Which production taxonomy releases do you support
Ask which taxonomy and entry point fit your reporting period and accounting framework. A newly announced release may still be an alpha or beta. As of 6 November 2026, the 2026 KVK iXBRL taxonomy is in its alpha phase; the published calendar provisionally schedules production for 31 December 2026. Ask how the supplier handles both supported production releases and testing of future versions. [1]
2 Can you handle our reporting framework
Confirm whether you need standard XBRL or iXBRL, and whether the workflow supports NL-GAAP, IFRS or another framework. Ask about extensions and any special foreign-parent filing route that actually applies to your entity. A supplier should explain the required deliverables for your case. [2]
3 How will you check the report layout
Ask to see the converted XHTML report alongside its approved source. Review tables, page references, symbols, and narrative disclosures. Agree who checks the readable report after conversion and after any later corrections. See how our tagging process works for the stages of a managed engagement.
Compare the evidence a provider can show for your reporting needs and agree who owns each task.
4 What does validation cover
Request both the technical validation output and an explanation of the human review. Check the filing information, applicable tags, report package and any relevant exemption flag. Passing technical checks alone does not establish that the reporting of treatment or legal exemption is correct. Agree who resolves each issue and approves the final version. [2][3]
5 Who submits and confirms the filing
Ask whether submission uses the designated KVK upload route or software connected to Digipoort, who has the necessary access, and who monitors the final response. A direct connection can reduce manual steps, but the engagement still needs an owner for successful-filing confirmation and any resubmission. Retain the accepted package and its confirmation together. [3]
6 How do you distinguish future rules from current obligations
Request a dated roadmap. The Article 408 transition for foreign group-head reports is currently expected for financial years starting on or after 1 January 2028. Other changes, including wider SBR block-tagging, need their own confirmed commencement rules. A roadmap should identify what is available now, what is being tested and what remains dependent on regulatory decisions. [2]
7 What support and costs are included
Ask for written scope covering conversion, tagging, revisions, submission, rejected-file fixes and support availability. Confirm who is responsible near your filing deadline and whether changing the approved source report adds fees. Compare the total cost of your reporting cycle, including internal staff time.

Frequently asked questions
Choose according to your team's capacity and reporting needs. Software requires someone to own preparation, tag, and review. A managed service can carry out agreed tasks, but your engagement should still specify approval and filing responsibilities.
No. The person responsible must monitor the response and retain confirmation of successful filing. A connection is a submission route, not evidence that a particular report was accepted.
Ask for the scope of conversion, tagging, review, revisions, submission and support, together with any additional charges. Confirm who handles corrections and retains the final package and filing confirmation.
Agree this before work starts, not when time is short. Ask for written confirmation of who handles final corrections, approval, submission and any resubmission in the days before your deadline, and what support is available then.
It depends on the written scope, so ask before you commit. Confirm whether changes to the approved source report add fees, and compare the total cost of your reporting cycle, including your own team’s time, rather than the headline price alone.
Yes. Our free sample conversion lets you review the converted XHTML report next to your approved source, so you can check tables, page references and narrative disclosures before agreeing scope.
