In the world of cross-border employment, Dutch hirers often assume they are fully protected as long as they work with NEN 4400-2 certified staffing agencies. After all, the SNA certification should ensure that your supplier meets Dutch labor and tax obligations. So what could go wrong?
Unfortunately, this assumption creates a false sense of security. In reality, even companies that only hire from certified partners can still be exposed to serious legal and financial risks when it comes to Third-Country Nationals (TCNs) who are seconded to Netherlands under EU posting arrangements.
Certification isn’t compliance
The NEN 4400-2 certification focuses on financial integrity, tax payments and payroll administration. All important elements, but it does not cover immigration law.
That means an agency can be fully certified while still deploying workers who do not hold valid Dutch residence rights.
For hirers, this creates a hidden compliance gap. You may think your staffing partner has everything in order, while in practice your company is facilitating a situation that violates Dutch immigration regulations.
And under current legislation, ignorance is no defense since the authorities may still hold you jointly liable for employing or facilitating the illegal stay of TCNs.
The legal grey zone of cross-border employment
This risk is especially high in cross-border service situations where a European company posts non-EU workers temporarily to Netherlands.
These employees often have valid work authorization under EU rules, but their right to reside in the Netherlands expires after 90 days, even though they may continue to work legally under European law.
Without a Dutch residence permit, the employee is technically residing illegally and any company that benefits from their labor can face sanctions, back payments and reputational damage.
So while your staffing partner might be SNA certified and NEN 4400-2 compliant, you could still be held accountable if these residence obligations are not met.
“Schijnveiligheid”: when compliance looks safe but isn’t
The real danger is that this problem remains invisible until it’s too late.
Many hirers assume that NEN certification automatically covers all legal obligations. But immigration compliance is a separate domain. Unfortunately one that falls outside the scope of Dutch labor auditing systems.
This creates “schijnveiligheid”, roughly translated as an illusion of safety.
Your administrative records may look perfect, your contracts may appear solid and your partner may proudly display the SNA logo. Yet if even one worker lacks a valid Dutch residence title, your company can still be drawn into enforcement procedures by the Immigration and Naturalisation Service (IND) or the Labour Inspectorate.
Shared chain responsibility
Dutch law takes a chain responsibility approach. This means liability doesn’t stop at your supplier but it extends throughout the entire contracting chain.
If an outstaffing agency or subcontractor is non-compliant, the end-client can still be held responsible, even if they were unaware of the issue.
Authorities increasingly view hirers as co-facilitators of illegal residence if they fail to verify compliance. In practical terms, this could mean administrative fines, exclusion from future contracts, or even criminal investigations in serious cases.
Prevention is the only protection
The only real safeguard is proactive verification.
Before hiring international staff through a European partner, ensure that both the right to work and the right to reside are fully covered. A Dutch residence permit is not a formality. It is a legal necessity for any Third-Country National staying longer than 90 days.
CIS helps employers and their partners close this compliance gap by securing Dutch residence permits quickly and digitally. Our process eliminates paperwork, ensures continuous legal residence, and protects both suppliers and end-clients from liability in the chain.
Conclusion
Working with certified partners is smart, but not sufficient.
True compliance goes beyond payroll integrity and includes immigration law, residence rights and chain accountability.
If your business relies on cross-border labor, it’s time to look beyond the certificate and make sure your compliance is real, not assumed.
