Dutch Foundation (Stichting) Audit Requirements

Key takeaways

A Dutch stichting only enters Title 9's reporting and audit framework if it operates a commercial enterprise (onderneming). A pure charitable foundation has no statutory audit obligation under Title 9, regardless of its size.
Even when commercial activities exist, the foundation must reach €6 million in commercial net turnover for two consecutive years before Title 9 applies (article 2:360(3) BW2).
Once within Title 9 scope, the foundation is classified using the same size criteria as BVs and NVs, with the 2024-updated thresholds. Only medium-sized and large foundations require a statutory audit.
Sectoral audit requirements (healthcare, education, pensions, ANBI, subsidy conditions) exist independently of Title 9 and can catch foundations that are entirely out of BW2 scope.

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.

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. Unless the STAK itself generates revenue from services or other commercial activity, it generally falls outside Title 9 on its own.

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, determine its size classification, and comply with the corresponding publication, disclosure, and (if medium or large) audit requirements. 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.

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:

Category	Total assets	Net turnover	Employees
Micro	≤ €450,000	≤ €900,000	< 10
Small	≤ €7.5 million	≤ €15 million	< 50
Medium	≤ €25 million	≤ €50 million	< 250
Large	Exceeds at least two of the medium thresholds for two consecutive years

For foundations operating within a group structure, 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. A foundation with modest standalone figures can easily qualify as medium or large once consolidation is factored in.

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). 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.

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.

A practical complication specific to foundations is the absence of shareholders. 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 to ten months. Publication must happen within eight days after adoption, with an absolute maximum of twelve months after the balance sheet date. Missing this deadline is an economic offence under the WED.

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.

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.

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. For larger ANBIs, the combination of donor expectations and subsidy conditions often creates a de facto audit requirement.

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 frequently require audited financial statements as a condition of the grant. 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.

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.

Step 1: Determine whether commercial activities exist

De Brug provides residential care and home care services funded through ZVW (Zorgverzekeringswet) and WLZ (Wet langdurige zorg) contracts. It charges fees to care recipients and invoices health insurers. These activities constitute a commercial enterprise under the Belastingdienst's functional test.

Step 2: Test the €6M turnover threshold

De Brug's net turnover from care activities was €8.4M in 2024 and €9.1M in 2025. Both years exceed €6M. The foundation has been within Title 9 scope since the 2024 financial year.

Step 3: Apply the size criteria

De Brug's figures for the 2025 balance sheet date: total assets €11.2M, net turnover €9.1M, average employees 142. De Brug exceeds the small criteria on assets (>€7.5M) and employees (>50). Two out of two consecutive years confirmed against 2024 figures (assets €10.8M, employees 131). De Brug qualifies as medium-sized.

Step 4: Confirm the audit obligation and check sectoral requirements

As a medium-sized foundation under Title 9, De Brug requires a statutory audit under article 2:393 BW2. Additionally, as a WTZi-registered healthcare institution, De Brug must comply with the CIBG annual reporting requirements and the healthcare audit protocol. The statutory audit under Title 9 and the sectoral WTZi audit can be combined into a single engagement, but the auditor must address both frameworks in the report.

Practical checklist for stichting audit assessments

Confirm whether the foundation operates any commercial activities by reviewing the articles of association, the actual operations, and the corporate income tax filing status with the Belastingdienst. If no commercial enterprise exists, Title 9 does not apply.
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.
Once Title 9 applies, collect total assets, net turnover, and average employee count for two consecutive balance sheet dates. Apply the 2024 size criteria and assess on a consolidated basis where subsidiaries or group companies exist.
If the foundation qualifies as medium or large, confirm the audit obligation under article 2:393 BW2. Check whether the article 2:403 group exemption applies.
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, subsidy conditions).
Document all of the above in the engagement acceptance workpaper before signing the engagement letter.

Common mistakes

Assuming a large stichting always needs an audit. A foundation managing €50M in endowment assets but conducting no commercial activities remains outside Title 9 entirely. The AFM has noted that auditors sometimes accept engagements for foundations where no statutory obligation exists.
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.
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.

Frequently asked questions

When does a Dutch stichting need a statutory audit?

A Dutch stichting needs a statutory audit only if it operates a commercial enterprise with net turnover of at least €6 million for two consecutive years AND qualifies as medium-sized or large under the Title 9 BW2 size criteria. A pure charitable foundation with no commercial activities has no statutory audit obligation under Title 9, regardless of its size.

Do donations and grants count toward the €6M turnover threshold?

No. Article 2:360(3) BW2 refers to net turnover from commercial enterprise activities only. Donations, grants, membership fees, and other non-commercial income do not count toward the €6 million threshold. Only revenue generated through participation in commercial trade qualifies.

Can a stichting have audit requirements outside of Title 9?

Yes. Several sectoral laws impose audit requirements independently of Title 9. Healthcare foundations must comply with WTZi reporting requirements, educational institutions fall under the Regeling jaarverslaggeving onderwijs, and pension fund foundations are supervised by DNB under the Pensioenwet. Subsidy conditions from provincial, municipal, or European bodies can also create de facto audit requirements.

Who appoints the auditor for a Dutch foundation?

Since foundations have no shareholders or members, the articles of association typically assign the appointment authority to the board of directors or to a supervisory board where one exists. Under article 2:393(2) BW2, if the general meeting does not appoint the auditor, the supervisory board may do so. If no supervisory board exists, the appointment defaults to the board of directors.
