Dutch ZZP Enforcement 2026: What HR Leaders Must Do Now

The Dutch Tax Authority (Belastingdienst) has shifted from warning companies about contractor misclassification to actively auditing them. Since January 1, 2025, the enforcement moratorium on the Wet DBA (Employment Relationships Deregulation Act) has ended, and from 2026 the penalties for demonstrable intent or gross negligence range from 10% to 100% of the back-assessed payroll tax, with retroactive assessments running back to January 1, 2025.

For HR leaders at companies with Dutch ZZP freelancers on their rosters, the liability window is already open.

The legislative picture has become more uncertain, not less. In March 2026, Minister Aartsen scrapped the clarification part of the VBAR bill that was supposed to resolve the definitional ambiguities in the law. A replacement framework, the Zelfstandigenwet (Self-Employment Act), is under development but is not expected before 2027 at the earliest.

The Deliveroo/Uber criteria issued by the Dutch Supreme Court remain the operative standard in the meantime.

HR teams need to understand how the assessment actually works, what an audit-ready HR process looks like, and what to do when a ZZP engagement fails the test.

What "false self-employment" (schijnzelfstandigheid) actually means

False self-employment (schijnzelfstandigheid in Dutch) occurs when someone is formally engaged as a freelancer (ZZP'er) but the actual working relationship has the characteristics of employment. The client is effectively the employer but is not paying payroll taxes, social security contributions, or employee benefits.

Under the Wet DBA, both client and contractor bear responsibility for getting the classification right. The Belastingdienst's position has been consistent: it looks at how the work is actually performed, not what the contract says.

As the KVK (Dutch Chamber of Commerce) states: "To the Tax Administration, it does not matter what is put down on paper. It matters how you work in practice. A model agreement may give you a false sense of security."

This matters enormously for HR teams because most contractor review processes focus on the contract, while the Belastingdienst focuses on actual practice.

The enforcement timeline: what has changed and when

Understanding what rules apply in which year is essential for calculating actual exposure.

Key nuances to understand:

• Retroactivity cap: For unintentional cases, corrections run back to January 1, 2025 only. For deliberate misclassification, the Belastingdienst can assess up to five years back
• "Soft landing" continues in 2026: The enforcement approach remains primarily corrective. Inspections typically start with an exploratory company visit rather than an immediate penalty. But a company visit can lead to a formal audit, and formal audits lead to back-assessments
• Government organizations face extra scrutiny: In 2026, public-sector bodies are specifically named in the Belastingdienst's enforcement plan
• Intent vs. negligence: Culpability fines apply where the Belastingdienst can show deliberate intent or gross negligence, for example, where previous warnings from the authority have been ignored

According to L&E Global, HR must now be able to demonstrate that the organization actively pursues a policy to prevent false self-employment, including established assessment processes, contract analyses, and periodic reassessments of the use of self-employed workers.

The Deliveroo standard: what the assessment actually tests

The Dutch Supreme Court's March 2023 Deliveroo ruling established that employment status must be assessed by examining all circumstances together, as no single factor is decisive. The court identified nine circumstances to weigh, and the February 2025 Uber ruling refined their application further, particularly the weight given to entrepreneurship.

The operative assessment framework combines three statutory criteria under Dutch civil law with the nine Deliveroo/Uber circumstances.

The three statutory criteria (Article 7:610 BW) for an employment relationship:

1. Authority relationship: Does the client direct or supervise how the work is executed?
2. Personal obligation to perform: Is the contractor required to do the work personally, with no practical right of substitution?
3. Payment of wages: Is the compensation structured as a salary rather than a commercial rate that prices in entrepreneurial risk?

Nine circumstances the Belastingdienst weighs in practice:

1. Does the contractor work under the client's direction and supervision?
2. Is the work embedded in the client's organization (i.e., does it closely resemble work done by the client's own employees)?
3. Does the contractor work exclusively or primarily for one client?
4. Can the contractor freely be substituted, and does substitution actually happen in practice?
5. Are working hours and location determined by the client?
6. Is the contractor's rate comparable to an employee's gross salary rather than a market rate that accounts for overhead and risk?
7. Does the client cover costs (tools, materials, expenses) that a genuine entrepreneur would bear?
8. What is the duration and continuity of the engagement?
9. Does the contractor behave as an entrepreneur in the broader market: multiple clients, their own branding, genuine commercial risk?

Rather than applying a checklist where a contractor can "pass" three factors and "fail" six, the Belastingdienst evaluates the overall picture. A contractor who works on-site every day, attends all-hands meetings, has the same manager for 18 months, and invoices for hours worked at a rate barely above their former employee salary is an employment relationship regardless of what the contract says.

What HR leaders are actually getting wrong

Most HR teams mistakenly review the ZZP agreement to confirm it includes standard contractor language (output-based, no supervision clause, substitution permitted), whereas the Belastingdienst audits how the work is actually performed.

Common patterns that create false self-employment risk:

• Converted employees: A contractor who was previously an employee at the same company doing the same role. Courts treat this pattern with particular skepticism
• Single-client dependency: A ZZP'er who earns more than 70-80% of their revenue from one client has limited evidence of genuine entrepreneurship
• Operational integration: The contractor attends team stand-ups, is included in the client's org chart (even informally), uses the client's tools, and works standard business hours
• Low hourly rate: A rate close to the employee's gross hourly pay is a signal the rate does not price in entrepreneurial risk. The Belastingdienst also applies a legal presumption threshold (rechtsvermoeden), currently proposed at EUR 38/hour, below which an employment relationship will be presumed unless proven otherwise
• Long-duration engagements: Extended contracts with no defined deliverable or project scope drift toward employment in character over time

HR should ask whether an inspector reviewing actual working practices would see an employee, rather than focusing solely on whether the contract reads like a contractor agreement.

The audit-readiness checklist for HR leaders

Before the Belastingdienst visits, HR teams with ZZP contractors on their roster should complete the following:

Step 1: Map every active ZZP engagement

Create a complete register of all Dutch ZZP contractors, including their start date, hourly rate, degree of client dependency, and on-site presence.

When you engage contractors through Deel, the platform holds start dates and hourly rates as standard contract fields.

Step 2: Test each engagement against the Deliveroo criteria

For each engagement, work through the nine circumstances with the line managers who understand the daily reality, rather than relying solely on procurement or contract managers.

Deel's platform features a Mass Misclassification Assessment to validate and update several workers' classifications at once.

Step 3: Flag high-risk engagements

High-risk signals include:

• Single-client dependency exceeding 70%
• Rate below or close to the EUR 38/hour rechtsvermoeden threshold
• Engagements exceeding 12 months with consistent work hours
• Contractors attending internal meetings as team members
• Former employees re-engaged as ZZP'ers within two years

Deel's Compliance Monitor assesses contractor engagements against local misclassification criteria and flags engagements whose characteristics align with those risk factors as elevated misclassification risk so you're always one step ahead.

Step 4: Build an audit-ready file

For each engagement, maintain:

• The statement of work or scope document (not just the general ZZP agreement)
• Evidence of genuine entrepreneurship: their own website, other clients, professional liability insurance
• Records of any Belastingdienst web module assessment results
• Notes from the engagement manager confirming working conditions

Step 5: Decide on each flagged engagement

For each high-risk engagement, HR has four options:

1. Restructure the engagement conditions to genuinely reflect independent work
2. Use a Contractor of Record (COR) to run local compliance checks and assume liability and indemnification for misclassification risk
3. Convert the worker to compliant employment through your own entity or an Employer of Record
4. Last resort: End the engagement

What happens when an engagement fails the test

If a ZZP engagement cannot be structured to genuinely reflect independence, here are the practical options.

Option 1: Restructure the engagement

In some cases, the engagement can be restructured to reduce classification risk by moving to a project-based deliverable model, reducing on-site presence, reducing single-client dependency, or ensuring the contractor genuinely exercises substitution rights. This requires cooperation from the contractor and the business unit, and needs documentation.

Restructuring works best when the underlying need is for a genuine service, not a permanent workforce augmentation. If managers describe the role as "we need someone in this seat doing X every week," restructuring is unlikely to produce a durable result.

Option 2: Hire using a Contractor of Record

A Contractor of RecorD lets you engage an independent contractor globally while Deel becomes the contractor's legal client of record — Deel manages the contract, compliance, invoicing, and payments on the client's behalf.

• Your organization directs the contractor's day-to-day work; Deel handles the paperwork, local compliance checks, and payment processing
• Deel assumes liability and indemnification for misclassification risk, reducing the client's administrative and legal exposure

Option 3: Convert to Employer of Record (EOR) employee

For ZZP engagements where the contractor is valued talent the business wants to retain, where the working relationship genuinely resembles employment, hiring through Deel's EOR solution in the Netherlands is typically the cleanest resolution.

Under an EOR arrangement:

• The worker is formally employed by the EOR provider's Dutch entity
• Payroll taxes, social security contributions (including pension, sick pay, and holiday allowance), and statutory benefits are handled compliantly under Dutch law
• The hiring company retains day-to-day direction of the work without carrying employer-of-record obligations directly
• The classification risk under the Wet DBA is eliminated entirely

For the Netherlands specifically, EOR removes the risk of the Belastingdienst finding an employment relationship and imposing retroactive assessments, because the employment relationship is already declared and properly structured. The worker's statutory sick pay, dismissal protections, and employee rights are all managed under Dutch law from day one.

The cost comparison: compliance now vs. assessment later

while some HR leaders may view EOR conversion as a cost increase. Organizations should compare the EOR cost against the potential cost of a Belastingdienst enforcement outcome, rather than treating it as a direct ZZP rate comparison.

A retroactive assessment for a typical senior ZZP engagement can encompass:

• Unpaid payroll taxes and social security contributions from January 1, 2025 onwards
• Employer's share of contributions for sick pay, pension, and insurance (which ZZP arrangements do not include)
• In cases of deliberate misclassification or ignored warnings: culpability fines of 10-100% of the assessment
• Employment law consequences: the reclassified worker may be entitled to an employment contract with dismissal protection from the date the relationship began

Deel's Misclassification Quiz gives organizations an indicative exposure estimate for each at-risk engagement, which makes this comparison concrete rather than hypothetical.

The legislative gap: why waiting for the Zelfstandigenwet is not a strategy

After the VBAR clarification bill was scrapped in March 2026, some HR leaders have reasoned that waiting for the Zelfstandigenwet will eventually provide clearer rules. This is not a viable compliance strategy for two reasons.

• First, the Zelfstandigenwet is expected no earlier than 2027, and must pass both chambers of parliament before it takes effect. The Deliveroo/Uber framework governs all audits until then
• Second, the liability exposure from ZZP engagements that began in January 2025 is already accruing. Waiting for new legislation does not rewind the clock on back-assessments for engagements that are currently at risk

The KVK's official guidance is clear: changing the legal structure of a business from an eenmanszaak to a BV or VOF does not change the employment relationship assessment. And business.gov.nl confirms that both client and contractor must be able to prove together that the relationship is not one of employment. The burden is shared.

Companies that have not yet audited their Dutch ZZP rosters are accumulating tax exposure with each passing month.

Get ZZP audit-ready with Deel

For HR teams managing global workforces that include Dutch ZZP contractors, Deel provides practical tools for this process:

• Mass misclassification assessment: Deel's mass misclassification assessment capabilities allow HR teams to validate the classification of multiple workers simultaneously using standardized criteria. This is particularly useful for large contractor rosters where conducting individual assessments takes prohibitive amounts of time
• Contractor of Record hiring: Deel becomes the legal client of record for independent contractors, handling all contract management, compliance, payments, and invoicing while assuming misclassification liability—allowing clients to direct work without administrative burden or legal exposure
• Employer of Record conversion: Deel's EOR solution in the Netherlands handles the full employment structure for workers transitioned from ZZP arrangements: employment agreements, payroll tax registration, statutory sick pay, pension, holiday allowance, and dismissal procedures under Dutch law
• For companies with ZZP contractors across multiple countries, Deel also provides Contractor Management to centralize classification, documentation, and compliance oversight in a single platform

Managing Dutch ZZP contractors in 2026 means working without a regulatory safety net: the VBAR is gone, the Zelfstandigenwet is years away, and the Deliveroo criteria are the only authoritative standard available. The companies best positioned are those that have already completed their roster audits, separated the genuinely independent contractors from the embedded workforce, and converted the latter to compliant employment before the Belastingdienst arrives.

Deel gives HR teams the infrastructure to make that transition without losing the talent.
