Why Octagon for international organisations
Generic EOR platforms treat every country as a field on a signup form. Host-state legal firms understand the agreements but cannot run payroll. Octagon sits inside the Hague international corridor as an active workforce partner to Europol and OPCW, with host-state agreement know-how, long-standing client relationships with those institutions, and operational experience handling diplomatic immunity and tax-privilege employment situations. The Hague hosts more than 200 international organisations. We have worked alongside them, from a Hague address, since 1987.
What makes us different
International organisations operate under host-state agreements, the Vienna Convention, and institution-specific employment regulations that sit outside standard Dutch employment law. Most HR providers have no experience with privileges and immunities, tax exemptions, or the distinction between internationally and locally recruited staff.
Octagon administers these frameworks as part of our standard service and has done so for three decades across institutions in The Hague and Brussels.
The typical approach
4 vendors. 4 contracts. No single owner.
The Octagon approach
1 partner. 1 contract. Full accountability.

Employment services
Standard Employer of Record services assume commercial Dutch employment law. International organisations operate under different rules: host-country agreements, privileges and immunities, tax exemptions, and social security waivers. Octagon structures employment contracts that account for these frameworks, ensuring that locally recruited staff are employed compliantly while the organisation retains full operational control. We handle BSN registration, 30% ruling administration, and municipal registration as part of the onboarding process.
Expertise
ICC, OPCW, Eurojust, Hague tribunals
The Hague hosts the ICC, OPCW, ICTY, and dozens of other treaty-based institutions, each with unique employment frameworks governed by host-country agreements and the Vienna Convention. Octagon has recruited and employed staff for these organisations for more than 30 years. We understand the distinction between internationally recruited and locally recruited staff, the privileges and immunities that apply to each, and the Dutch employment law obligations that sit underneath.
Europol, Eurojust, EDA, NATO-adjacent commands
Europol, Eurojust, EDA, and allied agencies operate under EU Staff Regulations and NATO grading structures. We supply contract professionals who understand these institutional cultures, procurement frameworks, and compliance requirements. Our candidates have prior experience inside these organisations or in closely adjacent roles.
Vienna Convention, bilateral agreements
International organisation staff may be exempt from Dutch income tax, VAT, and social security contributions. Managing these exemptions requires specialist knowledge of the applicable host-country agreement, the organisation-specific headquarters agreement, and Dutch tax authority procedures. Octagon administers these frameworks as part of our standard payroll and HR service.
Multi-lingual HR, cross-cultural
A typical international organisation in The Hague employs 20 or more nationalities in a single office. Recruiting, onboarding, and managing this diversity requires multi-lingual HR capability, cross-cultural sensitivity, and experience with BSN registration, 30% ruling administration, housing support, and municipal registration for international arrivals.
Managed Teams
Some international organisations need more than individual placements. They need a partner who can build and manage entire support functions: IT service desks, administrative teams, translation units, or project management offices. Octagon recruits, employs, and manages these teams under a single contract, with clear reporting lines, KPIs, and knowledge transfer protocols. Your organisation retains strategic direction while we handle operational delivery.
Years of institutional compliance checks, active procurement history, and people on the ground who know the hiring managers by name. That continuity is not something remote EOR platforms can acquire overnight.
Each treaty-based organisation in The Hague runs on a different host-state agreement with different tax, social security, and immunity provisions. Octagon reads these agreements for a living and structures employment contracts that align locally recruited staff with the organisation's framework.
Our Maanweg 174 office sits among Europol, OPCW, Eurojust, and the ICC. That physical proximity is not ornamental. It is how we keep active relationships with procurement teams, HR directors, and the wider diplomatic community in the corridor.
Internationally recruited staff may be exempt from Dutch income tax, VAT, and social security. Locally recruited staff may not. Handling that distinction cleanly requires specialist payroll and HR operations, which Octagon runs as standard.
International hires need BSN registration, housing, bank accounts, health insurance, and municipal registration. Octagon provides full settling-in support so your new hire can focus on the role from day one.
