The WTTA: why SNA certification is a smart move for you as a partner

What is the WTTA
The WTTA introduces a mandatory admission system for organisations that make workers available under the direction and supervision of a third party. The law takes effect on 1 January 2027. Soon, you'll only be allowed to supply labour with an official admission. Without admission, making workers available stops once enforcement begins in 2028.

Why this law is being introduced
The WTTA protects workers against issues such as underpayment, poor housing, and unsafe working conditions. It also creates a level playing field for all market parties, including foreign companies. Only organisations that meet the strict standards will be allowed to keep making staff available.

Good to know: the law applies more broadly than just to labour migrants. It covers making all workers available in the Netherlands.

Does the WTTA apply to you
The WTTA affects the entire chain of making workers available, directly or indirectly. Are you active as:

• An employment agency
• A secondment company
• A self-employment intermediary
• A payroll company
• Another party that makes workers available, even with a different type of contract
• A foreign party that makes workers available in the Netherlands

Then your business likely falls under the WTTA. It's not your label that decides this, but the actual structure of the working relationship and direction. This is exactly where many partners underestimate their role in the chain, and therefore their admission and SNA obligations. Don't assume the law only applies to traditional employment agencies.

When does making workers available apply
Three conditions determine this:

1. You lend a worker to a client
2. You receive payment for this
3. The worker works under the client's direction and supervision

What changes for you specifically
From 1 January 2028, the admission requirement applies, and the Labour Inspectorate actively enforces it. You'll then only be allowed to make workers available with an official admission from the NAU (Dutch Labour Supply Authority). Striive and other clients will only be allowed to work with admitted partners.

Aren't prepared in time? Then you risk:

• Losing assignments, since you can no longer make workers available without admission
• Major clients no longer being allowed to work with you
• Necessary changes to contracts, chain agreements, and internal processes
• Fines of up to €90,000 per violation, with a possible work stoppage in case of repeated violations
• Reputational damage

Key admission requirements
To gain admission, you need to meet requirements including:

• Registration in the Trade Register with labour-supply activity
• A Certificate of Conduct (VOG)
• A deposit of €100,000
• Demonstrably correct wage payments
• Demonstrable tax remittance
• Compliance with the WTTA framework of standards, covering tax, social, and employment law obligations, wage payment, tax remittance, pensions, and housing
• Compliance with collective labour agreements

You register for this in time through the official reporting portal.

Why SNA certification is a smart move now
Do you have a valid SNA certification? Then you benefit from the transitional arrangement. You can apply for admission without an inspection report, and you can keep supplying labour during the assessment, even if no decision has been made by 1 January 2028. This prevents your operations from being disrupted while your application is still pending.

Note: SNA certification isn't the same as WTTA admission. The certification forms a good basis and covers many existing requirements, but the WTTA introduces additional obligations. The two don't fully overlap. You always apply for admission separately, even with an SNA certification in hand.

Conditions for the transitional arrangement
To use the transitional arrangement:

• You have a valid SNA certification on 30 June 2027
• You register for the transitional arrangement between 1 November 2026 and 31 December 2026
• You apply for admission before 1 July 2027

The timeline at a glance

Are you already working on your SNA certification? Then you're ahead of these deadlines. Waiting until 2028 is too late, since registration for the transitional arrangement already closes in 2026.

Who's involved in implementation

• NAU (Dutch Labour Supply Authority): decides on your admission and manages the admission register
• Inspection bodies: assess your organisation against the framework of standards
• Dutch Labour Inspectorate: enforces the rules and imposes fines from January 2028

Passing on self-employed professionals
Do you work with self-employed professionals? As of 1 January 2026, the SNA standard has been extended with additional modules for Mediation and Intermediation. These modules ensure that you assess in advance whether an assignment suits a self-employed professional, and that you monitor for risks of disguised employment during the assignment.

Passing on a self-employed professional is only possible if you hold SNA self-employment module certification. Don't have this yet? Work through a fee agreement instead.

Three steps you can take now
Starting now helps you avoid risks and protect your market position:

1. Apply for your SNA certification, including the self-employment modules
2. Record all chain agreements
3. Schedule a baseline assessment against the WTTA standards, so you know exactly where you stand

Common mistakes to avoid

• Assuming the WTTA only applies to employment agencies
• Confusing SNA certification with WTTA admission
• Waiting until 2028 to prepare

Summary

• The WTTA introduces a mandatory admission system for labour suppliers, from 1 January 2027
• Without admission, you lose market access from 2028
• SNA certification gives you access to a smooth transitional arrangement
• SNA certification doesn't replace WTTA admission, but prepares you for it
• Start preparing now: waiting until 2028 is too late
