11 November 2025: Wtta (Labour Supply Act) passed

The new Labour Supply Act (Wtta) imposes stricter requirements on temporary employment agencies, payroll companies and secondment agencies. But the Wtta also has major consequences for companies that use their services. What does this mean for their personnel policy and administration?

On 11 November 2025, the Dutch Senate passed the bill for the Labour Supply Act (Wtta; Wet toelating terbeschikkingstelling van arbeidskrachten). The Wtta imposes stricter requirements on payroll companies, secondment agencies and temporary employment agencies (lenders). The aim of the bill is to protect workers, particularly migrant workers, and to combat unfair competition between companies. Below, we discuss the most important consequences of the Wtta.

Licensing system for lenders

The Wtta introduces a mandatory admission system for lenders. This means that lenders may only lend workers to other companies with the permission of the Ministry of Social Affairs and Employment. If they do so without permission, they are in breach of the lending ban and risk a fine. A public register lists which lenders are admitted.

The admission requirements are:

• Registration in the Trade Register of the Chamber of Commerce;
• Submission of a Certificate of Good Conduct for legal entities (no more than three months old);
• Providing financial security in the form of a deposit of € 100,000 (€ 50,000 for start-ups);
• Submitting an inspection report demonstrating compliance with the relevant laws and regulations (the so-called standards framework), including payment of the correct wages and taxes.

If the assessment is positive, a licence will be granted for four years. Once admitted, the lender is obliged to cooperate with periodic checks by the inspection body. If a lender does not (or no longer) meet the conditions, the licence may be suspended or withdrawn.

Obligations for hirers

It is not only temporary employment agencies that are subject to the stricter rules. Companies that hire temporary workers may only do so through authorised temporary employment agencies. If they fail to do so, they may also be fined.

In addition, hirers must:

• Register which workers have been made available and by which agency;
• Keep these records for seven years after the end of the calendar year in which the assignment ended;
• Provide the necessary information to the inspection body and cooperate in the preparation of an inspection report.

Entry into force of the Wtta

The Wtta is expected to enter into force on 1 January 2027. From 1 January 2028, the Labour Inspectorate will enforce the authorisation requirement.

A transitional arrangement will apply to give companies time to prepare. Anyone who submits an application for authorisation before 1 July 2027 and has a valid certificate from the Labour Standards Register (Stichting Normering Arbeid; SNA certificate) will not be required to submit an inspection report with their first application. This is because companies with an SNA certificate comply with the legal obligations relating to administration, finance and personnel policy. Companies that wish to make use of this transitional arrangement must report to the Ministry of Social Affairs and Employment between 1 November 2026 and 31 December 2026.
