WTTA is coming: Are you prepared?

The upcoming Provision of Personnel Accreditation Act (WTTA) regulation is set to fundamentally reshape the flexible labour market in the Netherlands. While much of the conversation focuses on what the law requires, far less attention is being paid to how prepared the market actually is, which is where the real risk lies.

2027 may seem distant, but the implications are already taking shape – and they affect both the suppliers that businesses rely on and the way workforces are managed. For many organisations, the question is not just what WTTA is, but whether their current set-up will still be viable once it comes into force.

Understanding WTTA and the new labour regulations

WTTA (Wet toelating terbeschikkingstelling van arbeidskrachten) introduces a mandatory admission system for all staffing agencies in the Netherlands. Its aim is to protect temporary workers, such as migrants, and to create a more transparent and fair labour market.

The law applies to traditional temporary employment agencies, payroll companies, secondment firms, small regional players and even international suppliers active in the Netherlands.

From 2027, all providers must have registered with the Dutch Temporary Employment Market Authority (NAU) to legally supply staff. This is a major step beyond the existing WAADI registration system. WTTA raises the bar for compliance, removing the loopholes some agencies previously used to minimise statutory costs.

Not every recruitment agency will make the transition

For years, the Dutch labour market has had two types of staffing providers: those that operate transparently and comply fully with labour regulations, and those that cut corners – for example, by avoiding StiPP pension contributions or misinterpreting their obligations under WAADI.

As the WTTA regulation comes into force, the market will inevitably shift. There is a common misconception that WTTA readiness is something agencies can fix closer to the deadline. It isn’t. Becoming compliant requires:

  • Structural alignment with legal and operational standards
  • Financial readiness, including the €100,000 security deposit
  • Proven processes, documentation and consistent track record

Recruitment agencies that fail to meet the new standards face a choice: raise prices and explain to clients why they didn't comply before or exit the market. This is not something that can be implemented in a matter of weeks. Some agencies simply won’t be able to meet the requirements, whether due to financial constraints or because their internal processes aren’t built for this level of compliance.

Choosing the right partner is a business-critical decision

The conversation around WTTA compliance has largely focused on agencies - who will qualify, who won’t and what needs to be done to be admitted. But for companies relying on flexible labour, the more important question is:

Are the partners you work with today going to be allowed to support you tomorrow?

Because from 2027 onwards, selecting a supplier will no longer be based only on speed, cost or availability – it will be based on compliance. Under the new labour law, working with non-registered agencies will no longer be permitted, meaning businesses will need to choose from a list of approved suppliers.

And that brings a new kind of responsibility: ensuring that your partner is not just preparing for WTTA but already operating in line with its principles. Companies can face substantial fines for non-compliance and unawareness of a supplier’s status will not be a valid excuse.

WTTA is not just a legal change – it’s an operational one

One of the biggest challenges we see is that many companies still underestimate what WTTA really means for them. It’s not only about checking whether a supplier has a licence. It’s about understanding the implications across the entire hiring process - from risk management to continuity of workforce supply.

For organisations operating with multiple suppliers or under an MSP model, the complexity increases further. Ensuring every supplier in your network is compliant requires visibility, coordination and expertise. This is where a knowledge partner becomes essential.

Not someone who reacts when the rules change, but someone who helps you navigate them before they do. The companies that will be in the strongest position in 2027 are the ones already taking this seriously today.
