Netherland’s Labour Provision Admission Act to go into effect in 2027

On 11 November 2025, the Netherlands passed the Labour Provision Admission Act (Wtta), which stipulates that, without official authorisation from the Dutch Labour Supply Authority (NAU), a business can no longer supply workers and hirers cannot engage with suppliers who have not been authorised.

The legislation is meant to address how the Dutch temporary employment sector has long struggled with issues such as underpayment, inadequate housing, and tax evasion. The system now in place, which requires registration under the Placement of Personnel by Intermediaries Act (Waadi) and allows for voluntary SNA certification, has not prevented rogue practices. The Wtta, approved by the Dutch Senator on 11 November, is intended to remedy this situation.

Wtta’s key points

The Wtta will take effect on 1 January 2027, impacting both suppliers and hirers. Companies are strongly advised to prepare for the new licensing system in advance to ensure compliance when the Wtta comes into force.

Who will be subject to the admission system?

A business is considered to be supplying workers if the following criteria are met:

• The supplier supplies an employee to a hirer;
• The supplier receives payment from the hirer for this service; and
• The employee works under the direction and supervision of the hirer.

This means that not only temporary employment agencies (uitzendbureaus), but also companies involved in payrolling and secondment (detachering) fall under the admission system. This also applies to foreign companies supplying workers in the Netherlands.

Businesses in which supplying workers is not the main activity (i.e. where it amounts to less than 10% of total turnover and a maximum of EUR 5 million per year) may be granted an exemption from the licensing requirement. There is also no mandatory licensing for collegial staff supplied without profit or for supplying within the same group of companies.

Admission requirements

The Wtta requires suppliers to be registered in the Dutch Trade Register with supply activities and possess a Certificate of Good Conduct (VOG). In addition, suppliers must provide a financial guarantee of EUR 100,000 (or EUR 50,000 for start-up companies with provisional admission). Suppliers must also comply with the standards framework, which means meeting statutory requirements regarding minimum wage payment, tax remittance and applying correct employment terms.

Enforcement

Periodic inspections will be carried out at both suppliers and hirers by private inspection bodies. Hirers are expected to check the public register to ensure that the supplier they intend to work with has been authorised.

From 1 January 2028, the Dutch Labour Inspectorate will enforce the licensing obligation. If a violation is detected, fines may be imposed of up to EUR 90,000 per offence. This applies to both suppliers and hirers. In case of repeat offences, the Inspectorate can shut down offending companies.
