As a hiring employer, you mitigate legal and fiscal liability by verifying the agency’s Waadi registration with the KVK before every placement, recording on-site identity and safety checks, confirming equivalent CAO pay in writing, and partnering with transparently registered agencies such as ACS (KVK 70790254).
1. What is the Waadi registration and verification duty?
Under the Placement of Personnel by Intermediaries Act (Waadi), every company supplying labour in the Netherlands must hold an active labour-supply registration in the KVK Trade Register. Hiring workers through an unregistered intermediary exposes the hiring company to substantial administrative fines from the Netherlands Labour Authority.
- Verify the agency’s KVK number using the official KVK Waadi check tool.
- Archive a dated verification record in your supplier compliance file.
- Repeat verification periodically alongside the Wtta admission register.
2. Understanding fiscal hirer liability (inlenersaansprakelijkheid)
If a staffing agency fails to remit payroll taxes (loonheffingen) or VAT for the hours worked at your site, the Dutch Tax Administration can hold the hiring employer liable. Under the Sham Arrangements Act (WAS), employers also share chain responsibility for ensuring workers receive their statutory and CAO wage.
- Payroll taxes and VAT associated with invoiced staffing hours.
- Chain liability for accurate CAO remuneration under the WAS.
- Importance of realistic hourly rates that cover all statutory employer contributions.
3. On-site identity verification and safety records
Even when staff are employed by an agency, the hiring employer retains on-site duties to verify identity from an original document on day one and provide documented workplace safety instructions.
4. Realistic rate breakdown as your first line of defence
An hourly rate that sits below the sum of gross CAO wages, holiday allowance, leave accruals, StiPP pension and statutory social security charges is an immediate red flag. Always request a transparent rate specification.
5. Written confirmation of role, CAO scale and hours
Document the job role, applicable CAO pay scale, shift allowances and weekly timesheet approval procedure in writing before deployment.
6. Transparent partnership with ACS Personeelsdiensten
ACS Personeelsdiensten is registered with the Dutch Chamber of Commerce under KVK 70790254 with active Waadi registration. We provide clear corporate documentation, written assignment confirmations and itemized invoices for every engagement.
