Netherlands Beneficial Ownership Register (KvK): UBO Data, Access Restrictions & the 2026 API
1. The Netherlands UBO Register: The State of Play in 2026
The Netherlands is home to approximately two million registered companies, making it one of Europe's largest corporate jurisdictions. For compliance teams, KYB platforms, and due diligence analysts working with Dutch counterparties, the UBO register is a critical data source — and right now, one of the most operationally complex to access in the EU.
The Dutch UBO register is maintained by the Kamer van Koophandel (KvK) — the Chamber of Commerce — as part of the Handelsregister (Trade Register). It was established under the Wet ter voorkoming van witwassen en financieren van terrorisme (Wwft), the Dutch Anti-Money Laundering and Anti-Terrorist Financing Act, transposing AMLD4 and AMLD5. Most entities were required to file by March 27, 2022.
Three events have dramatically reshaped the access landscape since 2022: the CJEU ruling that closed public access, the July 2025 Amendment Act that formally restricted the register to specific parties — but left those parties unable to access it directly — and the upcoming KvK UBO API due in Q2 2026, which will finally enable systematic programmatic access. Until then, the Netherlands sits in a uniquely dysfunctional position: a register with data but no functional access route for most legitimate users.
This article is part of Zavia.ai's Global Ownership Data Index, covering UBO and corporate data availability across 173 countries. The Netherlands is covered in the EU & EEA section, scored as Restricted for UBO access.
2. What Is a UBO Under Dutch Law?
The Wwft defines a UBO as the natural person who ultimately owns or controls a Dutch legal entity. The definition follows the EU standard closely but includes specific Dutch interpretations that matter for cross-border compliance work.
The 25% threshold
A natural person qualifies as a UBO if they directly or indirectly hold more than 25% of shares, voting rights, or ownership interest in the entity. Indirect ownership is calculated through the entire holding chain: a person holding 60% of a company that itself holds 50% of a Dutch BV qualifies, because their indirect stake (30%) exceeds the threshold.
Control by other means
If no individual meets the 25% threshold through ownership or voting rights, the "control by other means" test applies. This covers individuals who have the authority to appoint or dismiss the majority of the organisation's management, or who exercise equivalent dominant influence over the entity's decisions.
The "pseudo-UBO" rule
When exhaustive analysis cannot identify any natural person through either ownership or control tests, Dutch law requires the designation of a pseudo-UBO. This consists of all natural persons who collectively comprise the statutory senior management — typically the board of directors or managing directors (hoger leidinggevend personeel). Unlike some EU jurisdictions, the Netherlands does not use the term "last resort UBO" — the pseudo-UBO designation is applied universally where no individual UBO can be identified.
Under the EU Anti-Money Laundering Regulation (AMLR) applying from July 10, 2027, the threshold shifts from "more than 25%" to "25% or more." The Dutch Minister of Finance has already proposed this change at national level. Any person holding exactly 25% will qualify as a UBO. Companies with shareholders at exactly 25% will need to revise their UBO registrations.
Which entities must register?

| Sole proprietorships (eenmanszaken) | ✗ Exempt | — |
| Foreign entities with only a Dutch branch | ✗ Exempt | Must register UBOs in their country of origin |
3. What UBO Data Is Actually Available in the Dutch Register
The KvK register holds two tiers of information: data visible to a limited public and data restricted to authorities and approved institutions. The split is important — what Wwft institutions can access differs meaningfully from what is available to third parties today.
| Data Field | Held in Register? | Accessible? | Notes |
|---|---|---|---|
| Full legal name | ✓ Yes | ● Wwft/authorities only | Not publicly visible since Nov 2022 |
| Month and year of birth | ✓ Yes | ● Wwft/authorities only | Full date held but only month/year shared with institutions |
| Full date of birth (day included) | ✓ Yes | ● Authorities only | Not disclosed to Wwft institutions |
| Nationality | ✓ Yes | ● Wwft/authorities only | — |
| Nature and size of interest (%) | ✓ Yes | ● Wwft/authorities only | Banded ranges (25–50%, 50–75%, 75–100%) |
| Home address | ✓ Yes | ● Authorities only | Not disclosed to Wwft institutions |
| Identity document copy | ✓ Yes | ● Authorities only | Used for verification against BSN; not shared beyond competent authorities |
| Citizen service number (BSN) | ✓ Yes | ● Authorities only | Checked by KvK for verification; not disclosed externally |
| Ownership chain / corporate structure | ✗ No | ✗ No | Register shows the declared UBO, not the holding path |
| Historical ownership changes | ✗ No | ✗ No | Required under 6AMLD from July 2026 |
| PEP / sanctions flags | ✗ No | ✗ No | Must be cross-referenced from external sources |
The July 2025 Amendment Act formally grants Wwft and Wtt institutions access to the UBO register. But in practice, this access is not yet operational. Institutions cannot query the register directly and must rely entirely on clients requesting their own certified UBO extract from KvK and providing it manually. The KvK Dataservice UBO extract and UBO API are not expected until Q2 2026.
4. Who Can Access the Dutch UBO Register?
The Netherlands has gone through a turbulent three-phase access history since 2022. The current situation — where access is legally defined but practically unavailable for most authorised parties — is unique in the EU.
Current access categories (as of March 2026)
| Category | Legal Access | Practical Status | Method |
|---|---|---|---|
| Competent authorities (police, tax, FIU-NL, prosecution) | Full — all fields | Operational | Direct KvK access |
| Wwft/Wtt institutions (banks, notaries, insurers, accountants, lawyers) | Limited UBO data | ● Client extracts only | Client provides own KvK-certified extract; API from Q2 2026 |
| Persons with legitimate interest | TBD — pending lower legislation | Not yet available | Rules not yet published by Dutch government |
| Registered UBO (own data) | Own data only | Operational | Via My KvK / DigiD |
| General public | None | Closed since Nov 2022 | No access route |
The Amendment Act provides for a legitimate interest access category — but the lower legislation defining who qualifies and how applications are assessed has not yet been published. KvK will be the decision-making body once rules are in force. Until then, journalists, civil society organisations, researchers, and businesses wanting to verify counterparties have no formal access route to Dutch UBO data.
5. Is Access Free? Cost and Availability Breakdown
| Access Method | Cost | What You Get |
|---|---|---|
| KvK Handelsregister (basic company data) | Free (basic) / paid extracts | Company name, KvK number, RSIN, registration date, legal form, address, directors — no UBO data |
| KvK certified UBO extract (own company) | Free for the registrant | Full UBO data for own entity — designed to be shared with Wwft institutions pending API |
| KvK Dataservice UBO API (via eHerkenning) | Paid (pricing TBC) | Programmatic UBO data access for Wwft/Wtt institutions — not yet live; expected Q2 2026 |
| KvK Business Open Data Set (bulk) | Free | Location, registration date, activity, legal form, dissolution date — fully anonymised; no company names or KvK numbers |
| KvK Zoeken API (company search) | Fixed monthly + per-query | Entity search, basic firmographic data — no UBO or shareholder data |
| Legitimate interest access | TBD | Not yet available; rules unpublished |
The current certified extract model — where companies must request their own extract and submit it manually to their bank or notary — creates significant operational friction. It is a stopgap measure, not a scalable compliance workflow. The Q2 2026 KvK API is expected to replace this entirely for Wwft institutions.
6. Penalties for Non-Compliance
Dutch UBO non-compliance is enforced by the Bureau Economische Handhaving (BEH), a branch of the Dutch Tax Administration (Belastingdienst). Unlike France, which added new enforcement powers in 2025, the Netherlands has maintained consistent penalties since the register's inception.
Because financial institutions currently cannot verify UBO data directly, there is a material risk that the notary and bank reporting obligation — the duty to flag discrepancies to KvK — will be unintentionally neglected. The AFM (Netherlands Authority for Financial Markets) and DNB (Dutch Central Bank) have both flagged this gap. Institutions that fail to report discrepancies risk fines and criminal proceedings even where the non-compliance was unintentional.
The 7-day update window applies without exceptions. KvK has no legal power to grant deferrals — including for exceptional circumstances. Any change to a UBO's information — ownership percentage, address, new UBO arriving, existing UBO departing — must be reported within 7 days of the change becoming official.
7. Existing Legislation
| Legislation | Year | Key Provision |
|---|---|---|
| EU 4th AML Directive (AMLD4) | 2015 | Required member states to establish UBO registers for companies |
| EU 5th AML Directive (AMLD5) | 2018 | Required public access to UBO registers; Netherlands implemented in 2020 |
| Dutch UBO Register launch (Wwft implementation) | Sept 2020 | Register goes live; part of UBO data publicly accessible |
| UBO Register Trusts Implementation Act | Nov 2022 | Separate register for trusts and similar legal arrangements; trustees must register UBOs |
| CJEU Ruling (Cases C-37/20 & C-601/20) | Nov 2022 | Struck down blanket public access; KvK immediately closes register to public |
| Certified extract mechanism (KvK) | Jun 2024 | Companies can obtain own UBO extract to provide to Wwft institutions as interim workaround |
| Notary reporting requirement | Oct 2024 | Civil law notaries must report UBO data discrepancies discovered during due diligence |
| Amendment Act on Restricting Access to UBO Registers | Jul 2025 | Formally restricts access to Wwft/Wtt institutions and competent authorities; provides framework for legitimate interest category pending lower legislation |
| EU AML Package (6AMLD + AMLR) | 2024 adopted | Harmonised LIA rules, historical data, bulk/machine-readable access; deadline July 2026–2027 |
8. Upcoming Changes: The 2026–2027 Roadmap
1. KvK UBO API via eHerkenning (Q2 2026)
This is the most operationally significant change on the immediate horizon. KvK is building a structured Dataservice UBO extract and UBO API, accessible via eHerkenning — the Dutch government's business authentication system. Wwft and Wtt institutions will be able to integrate this directly into their KYC and CDD systems, replacing the current client-extract workaround entirely. Pricing has not yet been published. The API is expected in Q2 2026, though KvK has not confirmed a specific launch date beyond "second quarter."
The KvK UBO API will be accessible via eHerkenning — the Dutch business authentication system available only to entities registered in the Netherlands. Non-Dutch compliance teams, foreign Wwft-equivalent institutions, and overseas KYB platforms will not be able to access the KvK UBO API directly without a Dutch legal presence or intermediary.
2. Legitimate interest access rules (2026)
The Amendment Act created the legal framework for legitimate interest access, but the lower legislation defining who qualifies and how KvK assesses applications has not yet been published. This is expected to be shaped by 6AMLD transposition. Until the rules are formalised, there is no application process for journalists, researchers, civil society organisations, or businesses wanting to verify counterparties.
3. Presumed legitimate interest for journalists and civil society (July 2026)
Under 6AMLD, journalists, academics, and civil society organisations with AML-related work will receive presumed legitimate interest — automatic register access without individual approval. The Netherlands must transpose this by July 2026. Given that the legitimate interest rules are not yet published even for the standard category, 6AMLD compliance will require significant legislative movement in the next four months.
4. Historical ownership data (July 2026)
6AMLD requires all EU member states to provide legitimate-interest users with access to historical UBO records — showing when individuals became or ceased to be beneficial owners. The current Dutch register provides no historical data. This is a material gap for retrospective due diligence and financial crime investigations.
5. Threshold change: "more than 25%" to "25% or more" (July 2027)
The AMLR shifts the ownership threshold slightly. The Dutch Minister of Finance has already proposed this change at national level. Any person holding exactly 25% of shares, voting rights, or ownership interest will qualify as a UBO from July 10, 2027. Companies with shareholders at exactly 25% will need to revise their UBO registrations when the new rules take effect.
The 2026–2027 roadmap moves clearly toward more functional access. The KvK API in Q2 2026 resolves the most urgent operational gap for Dutch Wwft institutions. The 6AMLD changes will extend access to legitimate interest users and mandate historical data. Compliance teams should plan now for an API-driven workflow rather than the current client-extract model.
9. The Real Challenges of Accessing Dutch UBO Data
9.1 No functional access for Wwft institutions (until Q2 2026)
The most significant operational gap in the EU right now. Banks, notaries, insurers, accountants, and lawyers — all of whom are legally required to verify their clients' UBO data — cannot access the KvK UBO register directly. They depend entirely on clients requesting and submitting their own certified extracts. This creates friction, delays, and a material compliance risk, particularly for complex holding structures or uncooperative clients.
9.2 No legitimate interest access route (rules unpublished)
Unlike France, which has a functioning (if slow) legitimate interest application process, the Netherlands has not yet published the lower legislation defining who qualifies for legitimate interest access or how to apply. As of March 2026, there is no application process. Journalists, researchers, civil society, and businesses wanting to verify counterparties have no formal route to Dutch UBO data.
9.3 eHerkenning barrier locks out non-Dutch entities
Even once the KvK UBO API launches in Q2 2026, it will require eHerkenning authentication — a government identity system available only to Netherlands-registered entities. Foreign compliance teams, overseas Wwft-equivalent institutions, and non-Dutch KYB platforms will not be able to access it directly. The practical workaround will be via a licensed Dutch data provider or intermediary.
9.4 No ownership chain resolution
The Dutch UBO register records the declared UBO — the natural person at the end of the ownership chain. It does not map the intermediate corporate structure. A Dutch BV owned by a Luxembourg SARL owned by a Cayman Islands company: the register tells you who the declared UBO is; it does not show how control flows from the Cayman entity through Luxembourg to the Netherlands. Resolving the full chain requires combining Dutch data with corporate records from each intermediate jurisdiction.
9.5 KvK shareholder data is not structured
The Handelsregister does not provide structured, machine-readable shareholder data. Company filings only list the main shareholder, and the relationship between shareholding data and UBO data is not automatically resolved. For cross-border UBO verification workflows, this means Dutch KYB typically requires combining registry data with UBO register data from two separate sources — neither of which is easily accessible at scale.
9.6 No historical data
The current Dutch UBO register provides no historical ownership records. There is no way to determine who was the UBO six months ago, what ownership percentage they held before a restructuring, or when a particular individual was added to or removed from the register. This gap is significant for retrospective due diligence, litigation support, and financial crime investigations. It will not be addressed until 6AMLD transposition in mid-2026 at the earliest.
9.7 Compliance rate gaps
As of March 2024, approximately 80% of companies had completed UBO registration — meaning roughly 20% of Dutch entities have either incomplete or missing UBO data. The BEH is responsible for enforcement, but the combination of self-reporting and limited verification capacity means a meaningful portion of the register reflects what was filed rather than the current ownership reality.
10. How Zavia.ai Resolves Dutch UBO Access
Zavia.ai connects directly to KvK and the Netherlands' official company data infrastructure — providing structured, API-accessible UBO and corporate data for Dutch entities without requiring your team to navigate the eHerkenning registration process, manage client-extract workflows, or build and maintain a separate KvK integration.
🇳🇱 Netherlands UBO Data via the Zavia.ai API
One API endpoint. Real-time access to Dutch beneficial ownership, directors, shareholders, and company registry data — sourced directly from KvK and the Handelsregister. No eHerkenning account required.
- Real-time UBO queries for any Dutch KvK number
- Cross-border ownership chain resolution
- Corporate linkage — subsidiaries, parents, group structure
- Bulk data delivery — licensed file exports at scale
- Sanctions overlay and KYB verification workflow
- Historical company data and director history
- 173-country coverage — one integration, global reach
- Full reseller and redistribution rights available
Resolving the eHerkenning barrier
The KvK UBO API launching in Q2 2026 will require eHerkenning — a Dutch government authentication system unavailable to foreign entities. For non-Dutch compliance teams, overseas financial institutions, and global KYB platforms, this means the new API will not be directly accessible. Zavia.ai holds direct access and can deliver structured Dutch UBO data through a single international API endpoint, without any requirement for Dutch entity registration or eHerkenning credentials.
Cross-border ownership chain resolution
The Dutch UBO register tells you who the declared UBO is. It does not show you how they control the entity. For a Dutch BV owned through a Luxembourg SARL and a Cayman Islands holding company, Zavia.ai resolves the full ownership chain across all three jurisdictions — connecting Dutch KvK data with 173 countries of government-sourced corporate and ownership data in a single structured API response.
Bulk data delivery for compliance platforms
For compliance platforms, financial institutions, and data products that need Dutch UBO data at scale, Zavia.ai offers structured bulk data file delivery. Licensed extracts updated on a defined cadence, delivered in your preferred format. Full reseller rights available for redistribution use cases.
A Dutch BV whose declared UBO holds exactly 26% through two holding entities in different jurisdictions may appear compliant in the KvK register. Zavia.ai traces the full chain above and below the Dutch entity — surfacing indirect controllers, circular ownership structures, and cross-border linkages that the KvK register alone cannot show.
