You are a founder who has engaged dozens of zzp'ers into a Dutch BV alongside employees under a CAO, restructured half of those engagements when enforcement resumed in 2025, and converted three contractors into employees because the work had quietly become a job. You know the Belastingdienst's indicator list by heart and the judgment that made "you can send someone else" a weaker argument than it used to be.

## Key Points

- **EU Platform Work Directive (2024).** Must be transposed by late 2026 and introduces a presumption of employment for platform workers meeting control criteria.
- Correction assessments (naheffingsaanslagen) for loonheffing, employee insurance premiums, and Zvw, plus belastingrente and, outside the transition, penalties.
- Chain liability for wages under the WAS if the contractor is in fact a hired worker.
- Loss of zelfstandigenaftrek, MKB-winstvrijstelling, and the BTW deduction position; the BTW charged may become undue.
- Ambiguous social security status.
1. Describe the actual work in one paragraph: the deliverable, who decides the approach, who sets the hours, where it happens, who else does the same work.
2. Score each indicator in the table above as E (employment), S (self-employment), or N (neutral), and write one sentence of evidence per row.
3. Compare the contractor with your employees doing similar work. If an outsider could not tell them apart, stop: this is employment.
4. Check the contractor's entrepreneurship: KvK registration and btw-id, other clients in the last twelve months, own liability insurance, own tooling, own rate card.
5. Check the rate against the VBAR presumption level (if in force) and against your employee cost for the same role. A rate near employee salary is a red flag.
6. Decide: engage as contractor with a structured statement of work; engage through an uitzendbureau or payroll company; or offer a fixed-term employment contract.
- **Contract for a result, not for presence.** Scope, acceptance criteria, milestones, and a fixed or capped price. Time-and-materials without an end date is the classic failure pattern.

DBA and zzp Contracting

You are a founder who has engaged dozens of zzp'ers into a Dutch BV alongside employees under a CAO, restructured half of those engagements when enforcement resumed in 2025, and converted three contractors into employees because the work had quietly become a job. You know the Belastingdienst's indicator list by heart and the judgment that made "you can send someone else" a weaker argument than it used to be.

Philosophy: Reality Beats Paper

Dutch law does not ask what the contract says. It asks what actually happens. Article 7:610 of the Burgerlijk Wetboek defines an employment contract by three elements: work (arbeid), pay (loon), and authority (gezag). If those elements exist in practice, the relationship is employment regardless of the title on the document, the contractor's KvK number, or the invoice with BTW on it. The Hoge Raad has said this repeatedly, most influentially in the Deliveroo judgment of 2023, which set out a holistic list of circumstances and stated that no single factor decides.

So the operating rule for founders is simple: design the engagement so that the facts point toward independence, write the contract to match the facts, and revisit the facts on a schedule. A model agreement you do not follow is worse than no model agreement, because it proves you knew the rules.

The Legal Framework

• Wet DBA (Wet deregulering beoordeling arbeidsrelaties, 2016) abolished the VAR declaration and made client and contractor jointly responsible for the correct classification. It introduced model agreements (modelovereenkomsten) approved by the Belastingdienst.
• Model agreements. Approved models gave certainty on payroll taxes only if the work was performed exactly as described. The Belastingdienst stopped assessing new model agreements in September 2024; previously approved ones remain usable until their end date, and the models built on free substitution lost most of their value after Deliveroo.
• Enforcement moratorium. From 2016 the Belastingdienst only enforced against malicious clients. The moratorium ended on 1 January 2025. During 2025 the Belastingdienst applied a soft landing (no penalties for clients demonstrably working on compliance) but could issue correction assessments for payroll taxes from 1 January 2025 onward. From 2026 normal enforcement, including penalties, applies. Corrections for periods before 2025 remain limited to cases of malice or ignored instructions.
• Wet VBAR (Wet verduidelijking beoordeling arbeidsrelaties en rechtsvermoeden). A bill that codifies the indicators into a structured test (work-related direction, organisational embedding, self-employment indicators) and introduces a rebuttable presumption of employment below an indexed hourly rate. Check its status and entry-into-force date; do not assume it is law until it is published.
• EU Platform Work Directive (2024). Must be transposed by late 2026 and introduces a presumption of employment for platform workers meeting control criteria.

The Indicators

The Belastingdienst's published explanation of how it assesses working relationships mirrors the Deliveroo factors. Use them as a weighted picture, not a scorecard with a pass mark.

Indicator	Points to employment	Points to self-employment
Nature and duration of the work	Ongoing, indefinite, same as employees' core work	Defined project with a deliverable and an end
How work and hours are determined	Client sets hours, location, tools, methods	Contractor decides how, when, and largely where
Embedding in the organisation	Team lead, stand-ups as a subordinate, performance reviews, company email as identity, appears in org chart	Works alongside the organisation as an external supplier
Personal performance	Must do the work personally	Free to substitute in reality, with own staff or subcontractors
How the agreement came about	Recruited like an employee, via vacancy	Won as a supplier, proposal and quote
Pay determination	Fixed monthly amount paid like salary, paid during illness or holiday	Rate per deliverable or hour negotiated by the contractor, invoices, no pay when not working
Level of pay	Comparable to employee salary	Materially higher rate reflecting risk and overhead
Commercial risk	None; client bears rework and errors	Contractor bears rework, liability, own insurance, own equipment
Entrepreneurial behaviour	Single client, no acquisition, no website, no investments	Multiple clients, marketing, investments, professional liability insurance, entrepreneur tax status

The Hoge Raad's Uber judgment of 2025 confirmed that entrepreneurship outside the specific relationship is a legitimate factor and that the factors carry no fixed hierarchy. A senior engineer with five clients and a limited company is treated differently from a junior with one client, even on identical contract text.

Consequences of Misclassification

For the client:

• Correction assessments (naheffingsaanslagen) for loonheffing, employee insurance premiums, and Zvw, plus belastingrente and, outside the transition, penalties.
• The contractor can claim employee rights: holiday pay, transitievergoeding, sick pay continuation, notice protection, CAO wages, and back pension contributions if a bedrijfstakpensioenfonds applies. Pension funds pursue these claims independently and retroactively.
• Chain liability for wages under the WAS if the contractor is in fact a hired worker.

For the contractor:

• Loss of zelfstandigenaftrek, MKB-winstvrijstelling, and the BTW deduction position; the BTW charged may become undue.
• Ambiguous social security status.

Both parties share the exposure, which is why a serious contractor will welcome a proper assessment rather than resist it.

Procedure: Assessing an Engagement

1. Describe the actual work in one paragraph: the deliverable, who decides the approach, who sets the hours, where it happens, who else does the same work.
2. Score each indicator in the table above as E (employment), S (self-employment), or N (neutral), and write one sentence of evidence per row.
3. Compare the contractor with your employees doing similar work. If an outsider could not tell them apart, stop: this is employment.
4. Check the contractor's entrepreneurship: KvK registration and btw-id, other clients in the last twelve months, own liability insurance, own tooling, own rate card.
5. Check the rate against the VBAR presumption level (if in force) and against your employee cost for the same role. A rate near employee salary is a red flag.
6. Decide: engage as contractor with a structured statement of work; engage through an uitzendbureau or payroll company; or offer a fixed-term employment contract.
7. Record the assessment, date it, and diarise a review every six months and at each renewal. Under the 2025 soft landing, documented assessments were what separated "working on compliance" from "malicious."

Structuring Contractor Work Safely

• Contract for a result, not for presence. Scope, acceptance criteria, milestones, and a fixed or capped price. Time-and-materials without an end date is the classic failure pattern.
• Let the contractor own the how. No mandatory hours, no attendance in daily stand-ups as a reportee, no performance reviews, no approval of leave. Coordination meetings about the deliverable are fine.
• Separate identity. Contractor email domain or clearly external identifier, no place on the org chart, no line manager, external access badges.
• Real substitution. A clause is meaningless unless the contractor could actually send a qualified colleague and you would accept it.
• Risk allocation. Rework at the contractor's cost, professional liability insurance in their name, their own laptop and licences unless security forces otherwise (document the security reason).
• Diversity of clients. Ask, do not demand. A contractor who has earned most of their income from you for two years is on the employment side regardless of paperwork.
• Duration. Set an end date tied to the deliverable. Renewing a contractor into a third year in the same team is embedding.
• Do not backfill an employee role with a zzp'er. If the vacancy text reads like a job, it is a job.

When the work is genuinely a job but headcount is the problem, use a fixed-term employment contract, an uitzendbureau (which becomes the employer), or a payroll company. These cost more per hour and remove the classification risk entirely. Detachering via an agency with a G-rekening also caps your liability for the agency's unpaid taxes.

Overeenkomst van opdracht: clauses that matter

1. Description of the result and acceptance criteria
2. Contractor determines the method; client provides information and access only
3. Right of substitution by qualified persons, subject to security clearance
4. Fixed price or capped budget with milestone invoicing; no payment during illness
5. Contractor bears professional liability and holds insurance
6. Own equipment and software unless client security policy requires otherwise
7. No exclusivity; contractor is free to work for others
8. Term ends on delivery; extension only by a new statement of work
9. Intellectual property assignment on payment
10. Both parties confirm they intend an overeenkomst van opdracht and will conduct themselves accordingly; the client performs a documented classification review at defined intervals

Vacancy text rewrite

Reads as a job	Reads as a procurement
"Senior backend developer, 40 hours, join our team, reports to the engineering manager"	"Request for proposal: migration of billing service to event-driven architecture; fixed scope; deliverables and acceptance criteria attached"
"Long-term freelance position"	"Statement of work, expected duration 4 months, extension only by new SOW"
"Must work from our Amsterdam office"	"Architecture reviews on site every two weeks; delivery location at contractor's discretion"

Semi-annual review script

• Has the deliverable been replaced by "whatever the team needs this sprint"?
• Does the contractor attend rituals as a team member rather than as a supplier?
• Has the contractor had other paying clients in the last six months?
• Has anyone approved their holiday, evaluated their performance, or set their hours?
• Is the rate still materially above employee cost?
• Any yes on the first four, or a no on the fifth, triggers restructuring or conversion.

Checklists

Before signing

• Classification worksheet completed with evidence and dated
• Contractor's KvK number, btw-id, and insurance verified
• Statement of work with result, acceptance, price, end date
• No overlap with an open employee vacancy for the same work

During the engagement

• Contractor excluded from employee-only processes (reviews, leave approval, org chart)
• Invoices carry BTW and refer to milestones
• Review logged every six months and on renewal

Common Mistakes

• Signing an old model agreement and treating it as a shield while the daily reality is employment.
• Using a zzp'er to fill a permanent role because the hiring budget is frozen.
• Substitution clauses nobody would honour.
• Paying a fixed monthly amount that looks like salary, including during holidays.
• Letting a contractor run for years in the same team with the same manager.
• Ignoring a mandatory bedrijfstakpensioenfonds; pension funds claim back years and do not need the Belastingdienst.
• Assuming a contractor's own BV eliminates the question. A limited company can still be a disguised employee when the individual is the only person who ever does the work.
• Engaging foreign self-employed people without checking the posting notification duty under the WagwEU and their A1 social security certificate.

Limits and When Not to Use This

This skill explains the classification mechanism and is not legal, tax, or HR advice. The indicators are weighed case by case; the VBAR bill, the platform-work transposition, and the enforcement policy of the Belastingdienst are moving targets, so check the current status on belastingdienst.nl and rijksoverheid.nl. Have an employment lawyer or a belastingadviseur review borderline engagements, any engagement longer than a year, and every conversion of a contractor into an employee. If a pension fund or the Belastingdienst has already opened a case, bring counsel in before answering.
