Dutch Foundation (Stichting) Audit Requirements

The threshold question: does the stichting run a commercial enterprise?

Most legal entities in the Netherlands (BVs, NVs, cooperatives) fall within the scope of Title 9 BW2 automatically. Foundations do not. A stichting only enters Title 9’s reporting and audit framework if it operates one or more commercial enterprises (ondernemingen) on its own account. Article 2:360(3) BW2 sets this gate.

The Belastingdienst applies a functional test: does the foundation deploy capital and labour with the intention of generating revenue through participation in economic transactions? If it does, the Belastingdienst treats those activities as an enterprise for corporate income tax purposes. That same classification determines whether the foundation enters the Title 9 regime.

This means a pure charitable stichting that receives only donations and grants has no statutory audit obligation under Title 9. Not because it’s small. Because it’s out of scope entirely. The distinction matters for engagement acceptance: if the foundation’s articles of association prohibit commercial activity and the actual operations match, there is no Title 9 obligation regardless of the foundation’s total assets or the amounts flowing through its bank accounts.

Where practitioners run into trouble is with foundations that have mixed activities. A cultural stichting that runs a museum shop and rents event space is conducting commercial activities. A foundation that manages real estate for rental income is conducting commercial activities. What matters isn’t whether the foundation’s purpose is non-profit. It’s whether any of its actual activities meet the enterprise test.

The Belastingdienst looks at substance over form. A stichting whose articles say “charitable purposes only” but that invoices clients for consulting services or charges market-rate fees for services is operating a commercial enterprise regardless of what the articles say. Conversely, a foundation that charges below-cost fees purely to cover operating expenses (with the gap funded by subsidies) may not meet the enterprise test. The line sits at commercial intent and participation in economic trade, not at whether money changes hands.

One category that causes persistent confusion is the STAK (Stichting Administratiekantoor). A STAK holds shares and issues depository receipts (certificaten van aandelen). It does not typically conduct commercial trade itself. The commercial activities happen in the underlying BV whose shares the STAK holds. Unless the STAK itself generates revenue from services or other commercial activity, it generally falls outside Title 9 on its own. The BV it holds shares in has its own Title 9 obligations based on its own size classification.

What the €6 million turnover trigger means under BW2 article 2:360

Even when a stichting does operate a commercial enterprise, it still doesn’t enter Title 9 unless the net turnover from those commercial activities reaches €6 million for two consecutive financial years. This is the specific threshold set in article 2:360(3) BW2 for foundations and associations.

Net turnover here means turnover from the commercial activities specifically. Donations, grants, membership fees (for associations), and other non-commercial income do not count toward the €6M threshold. Only revenue generated through participation in commercial trade qualifies.

The two-consecutive-year rule works in one direction more quickly than most people expect. If a foundation’s commercial turnover exceeds €6M in year one and year two, it falls within Title 9 from the start of year two. But stepping back out requires falling below the threshold for two consecutive years as well. A foundation that drops to €5.8M in one year but bounces back to €6.2M the next year never leaves scope.

Once the €6M turnover threshold is met for two consecutive years, the full Title 9 framework applies. The foundation must prepare financial statements and determine its size classification. It must then comply with the corresponding publication and disclosure requirements, plus the audit obligation if it qualifies as medium or large. The foundation must also file these financial statements with the KVK Handelsregister, where they become publicly accessible.

Size classification once Title 9 applies

After a stichting enters the Title 9 regime, it gets classified using the same size criteria that apply to BVs and NVs. The EU raised these thresholds by approximately 25% effective for financial years starting on or after 1 January 2024, implemented in the Netherlands by the Implementatiebesluit Richtlijn verhoging grensbedragen dated 5 March 2024.

The current thresholds (applicable from financial year 2024) require a foundation to meet at least two of the following on two consecutive balance sheet dates:

For foundations operating within a group structure (common for holding foundations and STAKs), the size criteria must be assessed on a consolidated basis. Article 2:396(2) BW2 requires the foundation to include the financial data of its subsidiaries and group companies when determining which size category applies. A foundation with modest standalone figures can easily qualify as medium or large once consolidation is factored in.

The two-consecutive-year rule applies here as well. A foundation that exceeds the small thresholds in 2024 and 2025 becomes medium-sized from the 2025 financial year onward. If it drops back below in 2026 and 2027, it reverts to small for the 2027 financial year.

Which foundations actually need an audit?

Micro and small foundations have no statutory audit obligation under Title 9 (article 2:396 BW2). They benefit from reduced publication requirements and do not need to prepare a management board report.

Medium and large foundations must have their financial statements audited by a registered auditor (registeraccountant) or an accounting consultant authorised to certify financial statements (article 2:393(1) BW2). The general meeting appoints the auditor. Since foundations have no general meeting of shareholders or members, the articles of association typically assign the appointment authority to the board itself or to a supervisory board where one exists.

Non-compliance with the audit obligation is an economic offence under article 1(4) of the Wet op de economische delicten (WED). Any stakeholder can require a foundation to comply with its audit obligation through article 2:393(8) BW2. In practice, this means a creditor, the tax authorities, or a subsidy provider can force the issue if a foundation that should be audited isn’t.

The article 2:403 BW2 group exemption also applies to foundations. If a parent entity includes the foundation’s financial data in its consolidated financial statements and issues a liability declaration (403-verklaring), the foundation may be exempt from its own standalone audit. This structure appears frequently in healthcare groups where a holding stichting consolidates several operating foundations.

For foundations that do require an audit, the scope of that audit follows the same rules as for any other Dutch legal entity. The auditor examines whether the financial statements provide the insight required by law (the getrouw beeld requirement) and comply with the provisions of Title 9 BW2. The auditor must also verify the consistency of the management board report (bestuursverslag) with the financial statements, which is required for medium and large entities.

A practical complication specific to foundations is the absence of shareholders. In a BV or NV, the general meeting of shareholders appoints the auditor. A stichting has no shareholders and no members. Article 2:393(2) BW2 provides that if the general meeting does not appoint the auditor, the supervisory board may do so. If no supervisory board exists (which is common for smaller foundations), the appointment authority defaults to the board of directors under the foundation’s articles of association. The auditor should verify that the engagement letter reflects the correct appointment authority, because an auditor appointed by a body without the legal authority to do so faces a validity question on the entire engagement.

One more point that catches teams off guard: the filing deadline. Foundations within Title 9 scope must prepare financial statements within five months of the balance sheet date (article 2:394(2) BW2). The board can extend this by five months, bringing the total preparation deadline to ten months. Publication (filing with KVK) must happen within eight days after adoption by the board, with an absolute maximum of twelve months after the balance sheet date. Missing this deadline is an economic offence under the WED, and KVK has been increasingly active in monitoring compliance.

Sectoral audit requirements outside Title 9

Title 9 is not the only source of audit obligations for Dutch foundations. Several sectoral laws impose their own requirements, and these often catch foundations that would otherwise be out of Title 9 scope entirely.

Healthcare foundations (zorginstellingen) must comply with the Wet toelating zorginstellingen (WTZi) and the annual reporting requirements set by the CIBG. The Regeling verslaggeving WTZi requires an audited annual report from every healthcare institution above a certain revenue threshold, regardless of whether the stichting operates a commercial enterprise under BW2. The audit must follow the specific healthcare audit protocol (HKZ/WTZi controleprotocol).

Educational institutions structured as stichtingen fall under the sectoral reporting requirements of the Onderwijsinspectie. Schools and universities must submit audited annual accounts following the Regeling jaarverslaggeving onderwijs (RJO). This obligation exists independently of Title 9.

Pension fund foundations (pensioenfondsen) are supervised by De Nederlandsche Bank (DNB) and must comply with the Pensioenwet, which imposes its own audit and reporting framework. The Wet verplichte beroepspensioenregeling adds a similar layer for professional pension funds.

ANBI-status foundations face reporting requirements from the Belastingdienst. While ANBI rules do not impose a statutory audit, they do require publication of financial information on the foundation’s website, including a statement of income and expenditure. For larger ANBIs, the combination of donor expectations and subsidy conditions often creates a de facto audit requirement even where no statutory one exists.

The practical implication for auditors: when you’re assessing whether a stichting needs an audit, checking Title 9 alone isn’t sufficient. You need to identify the sector the foundation operates in and check for sector-specific reporting laws. A charitable stichting running a small community health clinic with €2M in ZVW-funded revenue might be well below the Title 9 thresholds but fully within scope of WTZi audit requirements.

Subsidy conditions create a separate layer entirely. Provincial and municipal governments, the European Commission, and national funds (like ZonMw for health research or NWO for scientific research) frequently require audited financial statements as a condition of the grant, even when the recipient stichting has no legal audit obligation under Title 9 or sectoral law. These aren’t statutory audits in the BW2 sense, but they still require the work of a registered auditor and produce an auditor’s report. For a foundation that relies heavily on subsidies, the de facto audit burden can be just as significant as a statutory obligation. The auditor’s responsibilities differ in scope, though: a subsidy audit typically follows a specific audit protocol prescribed by the subsidy provider, not the full Title 9 framework.

Worked example: Stichting De Brug Zorggroep

Scenario: Stichting De Brug Zorggroep is a healthcare foundation based in Utrecht that operates two residential care facilities and a home care division. It was founded in 2018 and has grown steadily. The board wants to know whether a statutory audit is required for the 2025 financial year.

The engagement partner signs off on acceptance. A reviewer would see: the commercial enterprise test documented, the two-year turnover threshold confirmed, the size classification supported by six data points across two years, and both Title 9 and sectoral audit obligations identified.

Practical checklist for stichting audit assessments

1. Confirm whether the foundation operates any commercial activities by reviewing the articles of association and the actual operations, then confirming the corporate income tax filing status with the Belastingdienst. If no commercial enterprise exists, Title 9 does not apply.
2. If commercial activities exist, obtain net turnover figures for the two most recent consecutive financial years and compare against the €6M threshold in article 2:360(3) BW2. Document the comparison in the acceptance file.
3. Once Title 9 applies, collect total assets, net turnover, and average employee count for two consecutive balance sheet dates. Apply the 2024 size criteria (article 2:396 BW2) and assess on a consolidated basis where subsidiaries or group companies exist (article 2:396(2) BW2).
4. If the foundation qualifies as medium or large, confirm the audit obligation exists under article 2:393 BW2. Check whether the article 2:403 group exemption applies (parent consolidation with liability declaration).
5. Regardless of the Title 9 outcome, identify the foundation’s sector and check for sector-specific audit requirements (WTZi for healthcare, RJO for education, Pensioenwet for pension funds, ANBI reporting requirements, subsidy conditions from provincial or municipal governments).
6. Document all of the above in the engagement acceptance workpaper before signing the engagement letter. Include the legal basis for the audit obligation and the specific audit protocol that applies.

Common mistakes

• Counting donations and grants toward the €6M turnover threshold. Article 2:360(3) BW2 refers to net turnover from commercial enterprise activities only. Subsidies and donations are not commercial turnover. Mixing these figures inflates the apparent obligation.
• Forgetting to assess on a consolidated basis. A holding stichting with individually small subsidiaries may exceed the size thresholds when consolidated. Article 2:396(2) BW2 requires the auditor to include subsidiary and group company data in the size classification assessment. Missing this step can result in classifying a medium-sized group as small.
