How does an employer of record handle data privacy compliance?
An employer of record handles data privacy compliance by acting as the legal employer of your workforce and assuming full responsibility for how employee personal data is collected, stored, processed, and protected under applicable law. In practice, this means the EoR operates as a data controller or joint data controller alongside the client company, bound by the same regulatory obligations that apply to any direct employer. The sections below unpack the specific questions that arise most often when businesses evaluate EoR arrangements through a data privacy lens.
What data does an employer of record actually process?
An employer of record processes a broad range of personal data on behalf of the employees it legally employs. This includes identity documents, tax identification numbers, bank account details, salary information, social security contributions, pension records, leave balances, and employment contracts. In cross-border scenarios, it also covers immigration documents such as work permits and visa applications.
The scope of data processing is directly tied to the EoR’s legal obligations as an employer. To run payroll correctly, the EoR must hold accurate financial and tax records. To administer benefits, it needs personal and sometimes medical information. To comply with immigration law when sponsoring non-EU workers, it processes passport data and residence permit details. This is not discretionary data collection; it is legally mandated by the jurisdictions in which the EoR operates.
For businesses using an EoR in the Netherlands specifically, this data processing occurs within the framework of Dutch labour law, the Dutch Tax Authority’s requirements, and the Uitvoeringsinstituut Werknemersverzekeringen (UWV) for social insurance. Each of these regulatory bodies imposes its own data retention and reporting obligations, all of which the EoR must satisfy on the client’s behalf.
How does an employer of record ensure GDPR compliance?
An employer of record ensures GDPR compliance by implementing the same data protection obligations that apply to any European employer: lawful basis for processing, data minimisation, purpose limitation, storage limitation, and enforceable data subject rights. A credible EoR will have documented policies, processing agreements, and technical safeguards in place before onboarding a single employee.
In practical terms, GDPR compliance for an EoR involves several concrete measures:
- Data Processing Agreements (DPAs): The EoR must establish formal agreements with the client company that define each party’s role, the categories of data processed, and the security measures in place.
- Lawful basis for processing: Most employee data is processed under the legal obligation or contractual necessity bases under GDPR Article 6, not consent, which is considered inappropriate in employment relationships due to the inherent power imbalance.
- Data minimisation: The EoR should collect only the personal data strictly necessary for payroll, tax, and HR administration, nothing more.
- Access controls: Employee data should be accessible only to authorised personnel within the EoR and, where relevant, the client company.
- Breach response protocols: A GDPR-compliant EoR will have a documented process for identifying, containing, and notifying the relevant supervisory authority of a data breach within the 72-hour window required by law.
Third-party certifications provide an additional layer of assurance. NEN 4400-1 certification, the Dutch quality standard for temporary employment agencies, requires regular audits that cover financial and administrative compliance, including the handling of employment records. Businesses should treat this certification as a baseline indicator of operational discipline, not a substitute for specific GDPR due diligence.
Who is responsible for data privacy, the EoR or the client company?
Responsibility for data privacy is shared between the EoR and the client company, but the split is not equal. The EoR, as the legal employer, is the primary data controller for all employment-related personal data. The client company typically acts as a joint controller or data processor for the operational data it handles directly, such as performance records, project assignments, and day-to-day work communications.
This distinction matters because it determines who bears liability in the event of a data breach or regulatory investigation. If an EoR mishandles payroll data, the EoR is the responsible party before the Dutch Data Protection Authority (Autoriteit Persoonsgegevens). If the client company misuses employee performance data it holds independently, the client bears that liability.
The boundary between these roles should be explicitly defined in a written Data Processing Agreement before the engagement begins. Ambiguity in this document creates legal exposure for both parties. A well-structured DPA will specify which party controls which categories of data, how data is shared between the two organisations, and what happens to that data when the engagement ends.
Client companies should not assume that delegating employment to an EoR transfers all data privacy risk. The client retains responsibility for any personal data it independently collects, processes, or stores about the workers, regardless of who holds the employment contract.
What happens to employee data when an EoR engagement ends?
When an EoR engagement ends, employee personal data must be handled in accordance with GDPR’s storage limitation principle and applicable Dutch retention requirements. The EoR is legally obligated to retain certain employment records for defined periods; Dutch tax law, for example, requires payroll records to be kept for seven years. Data that no longer serves a legal or contractual purpose must be securely deleted or anonymised.
The offboarding process should be governed by the same Data Processing Agreement that covered the active engagement. A reputable EoR will have a documented data retention and deletion policy that specifies:
- Which categories of data are retained, and for how long, based on legal obligations
- The process for transferring relevant records to the client company or the employee upon request
- How data is securely destroyed once retention periods expire
- Who is notified when deletion is completed
If the client company transitions to its own Dutch legal entity after an EoR arrangement, a common progression for businesses testing the market, the data transfer to the new entity must itself comply with GDPR. This includes ensuring the receiving entity has an appropriate lawful basis to hold and process the transferred records.
What should businesses look for in an EoR’s data privacy practices?
Businesses should look for an EoR that treats data privacy as an operational standard rather than a box-ticking exercise. The minimum indicators of a credible data privacy posture are a clear Data Processing Agreement, documented GDPR policies, a named data protection contact, and evidence of regular compliance audits. Certifications such as NEN 4400-1 signal that the EoR undergoes independent scrutiny of its administrative practices.
Beyond certifications, the following factors distinguish a compliance-first EoR from one that simply claims compliance:
- Transparency about data flows: The EoR should be able to explain precisely what data it collects, where it is stored, who can access it, and how long it is retained, without hesitation.
- Modern HRM systems: Platforms built with data security by design, such as role-based access controls, encrypted data storage, and audit trails, reduce the risk of inadvertent data exposure.
- Proactive communication: A trustworthy EoR will notify clients promptly if regulatory changes affect how employee data must be handled, rather than waiting to be asked.
- Clear DPA terms: The Data Processing Agreement should define controller and processor roles unambiguously, not leave them open to interpretation.
- Demonstrated audit history: Regular third-party audits, not just self-assessments, provide independent verification that policies are being followed in practice.
The question of EoR data protection is ultimately a question of institutional maturity. An EoR with decades of operational experience in a regulated market will have encountered and resolved the edge cases that newer providers have not yet faced.
