A Netherlands PEO, as the phrase is used by global hiring vendors, is not the American co-employment product transplanted to Europe: Dutch law does not recognise two employers sharing one employment relationship the way US co-employment does. What is actually sold under the label is an employer of record arrangement, in which the provider's Dutch entity is the sole legal employer, supplies the worker to you, and must therefore comply with the Dutch rules on employment contracts and on businesses that supply personnel, including registration under the Waadi, the Dutch act governing the allocation of workers by intermediaries.
What a PEO arrangement actually is under Dutch law
When a provider employs someone in the Netherlands and places their labour at your disposal, Dutch law treats it as supplying personnel, the same legal frame that covers temporary employment agencies and secondment firms. The government's guidance for businesses is explicit: every intermediary that supplies workers in the Netherlands must be registered in the KVK Business Register with a registration stating that it supplies personnel, the Waadi registration, and the hirer is expected to run the KVK Waadi check on its supplier. Both sides carry risk for getting this wrong: an unregistered supplier can be fined, and so can a hirer doing business with one. A vendor selling you a Netherlands PEO that cannot show its Waadi registration is offering an arrangement that starts non-compliant.
The Dutch employment rules the provider carries
The provider, as legal employer, owes the worker the full Dutch frame. A written statement of core terms is due quickly: employer and employee details, workplace, role, start date, any trial period, salary breakdown and working hours within a week of starting, and holiday entitlement, other leave and dismissal procedures within a month. Fixed-term contracts hit the chain rule: after three consecutive temporary contracts, or three years of them, the employee must receive a permanent contract, unless a collective labour agreement varies the rule. Statutory notice for the employer starts at one month and grows by a month for every five years of service, capped at four months; the employee's default is one month, and if a contract sets the employee's notice longer, the employer's must be at least double. A sector CAO can override several of these settings, so the provider must check coverage rather than assume the statutory defaults.
Chain liability and the certification deadline
Hiring supplied labour in the Netherlands carries chain liability: if the supplier underpays its workers, the hirer can be held responsible, which is why the government points hirers toward due diligence and toward suppliers holding the SNA quality mark, which offers protection against recovery of unpaid payroll taxes. The regime is tightening further: from 1 January 2027, businesses that supply staff must be certified by the Ministry of Social Affairs and Employment, a requirement aimed at ending the exploitation the loosely regulated end of the staffing market became known for. For a buyer, the practical consequence is a short checklist that will only get shorter to ignore: Waadi registration now, SNA mark as risk reduction, and a provider with a credible path to the SZW certification before the deadline.
What to check in a Netherlands EOR provider
Verify the Waadi registration through the KVK check yourself; it is public and takes minutes, and doing so is exactly what the government advises hirers to do. Ask whether a collective labour agreement applies to the provider or the role, because CAO coverage changes contract conversion timelines, pay floors and notice beyond the statutory baseline. Ask how the provider handles the fixed-term chain rule for a role you expect to run past three years, since the conversion to permanent is automatic and a provider that plans around it badly hands you a surprise. And get the full employer cost stack itemised: Dutch employer contributions, holiday allowance and any CAO obligations, on top of the fee. Contracts, the applicable CAO and Dutch law control; nothing on this page is legal advice.
Questions people ask about netherlands peo
Is co-employment possible in the Netherlands?
Not in the US sense. The arrangement sold as a Netherlands PEO is an employer of record structure: the provider's Dutch entity is the sole legal employer and supplies the worker to you, which places the relationship under the Dutch rules for intermediaries that supply personnel.
What is a Waadi registration and does my provider need one?
The Waadi is the Dutch act on the allocation of workers by intermediaries. Any business supplying personnel in the Netherlands must be registered in the KVK Business Register as doing so, and hirers are expected to check this. Both an unregistered supplier and its hirer risk fines.
What notice period applies to a Dutch employee?
The employer's statutory minimum is one month, extended by one month for every five years of service up to four months; the employee's default is one month. Contracts and collective labour agreements can vary these within limits, so the specific contract governs.
How long can fixed-term contracts run in the Netherlands?
Three consecutive temporary contracts, or three years of them, is the ceiling under the chain rule; past it the employment becomes permanent, unless an applicable collective labour agreement sets different terms.
