Dutch Provision of Personnel Accrediation Act ("WTTA") adopted: stricter rules for the flexible labour market
14-11-2025
On November 11th, 2025, the Dutch Senate approved the Provision of Personnel Admission Act (Wet toelating terbeschikkingstelling arbeidskrachten, "WTTA"). This Act will come into effect on January 1st, 2027 and will have significant implications for companies that supply workers (such as temporary staffing agencies and secondment firms), but as well for companies that hire temporary workers.
What is the purpose of the WTTA and who is this Act intended for?
The WTTA introduces a new system for the supply of labour. It's aim is to improve the position of workers – particularly migrant workers – and to ensure fair competition in the labour market. This means that the Act imposes requirements not only on agencies that provide temporary staff, but also on companies that hire these workers.
A mandatory registration requirement will apply to all companies, both in the Netherlands and abroad, that provide temporary workers in the Netherlands. This applies not only to temporary staffing agencies, but also to, for example, sub-contractors, payroll companies and secondment agencies.
What does the WTTA mean for companies that supply workers?
From January 1st, 2027, all temporary employment agencies must register with the Dutch Temporary Employment Market Authority (NAU) in order to obtain a licence. Only then will they be allowed to supply workers.
To be granted a permit, the supplier must meet several conditions, including being registered with the Dutch Chamber of Commerce, providing a Certificate of Good Conduct (VOG), paying a security deposit of € 100,000 and demonstrating compliance with the law (e.g. minimum wage and working/rest time regulations).
Companies that do not have a licence or violate the rules will face substantial fines starting January 1st, 2028. In the worst case scenario, their business could be temporarily shut down or their licence revoked in the event of repeated violations or fraud.
What does the WTTA mean for hiring companies?
From 2027 onwards, it will be crucial for companies hiring temporary workers to ensure they only work with suppliers who have a valid NAU permit. If they fail to do so, they too could face fines. This means that companies hiring workers must actively check whether their supplier is authorized. Fortunately, an official register of authorized labor suppliers will be made available, making it easier to see who complies with the new regulations.
When should action be taken?
The WTTA will come into force on January 1st, 2027, so it's time to start preparing!
From that point onward, companies wishing to continue providing temporary labor must register with the NAU. The first assessments of companies will begin in July 2027.
If a company already holds an SNA quality mark, it can benefit from a transitional arrangement, with registration available between November 1st and December 31, 2026.
Starting January 1st , 2028, the Dutch Labor Inspectorate will begin enforcing the regulations. Companies without a permit, as well as the hiring companies working with them, can expect substantial fines.
How are you preparing for the WTTA and what will change from January 1st, 2027?
With the WTTA on the horizon, the flexible labour market is changing significantly. This law introduces stricter rules for the provision of labor and ensures that these rules apply to all parties involved – both suppliers and hirers. Starting January 1st , 2027, labor suppliers will be required to obtain a permit from the NAU. Companies hiring temporary workers will need to actively check whether their supplier complies with the new requirements.
Proper preparation for the new regulations will prevent unpleasant surprises, such as fines or even a business shutdown.
