This is one of the costliest misunderstandings a student can carry: the exemption from Dutch basic health insurance ends the day paid work or a paid internship begins, and nothing flags the change. Backdated premiums and a fine tend to surface months later, long after the status quietly shifted.
No, not if you're purely here to study. Full-time bachelor's or master's students under 30 who are in the Netherlands solely for their degree are exempt from the Dutch basic health insurance obligation — you're not even allowed to take out Dutch public insurance in that situation. Keep your home-country coverage, EHIC if you're from the EU/EEA, or a private international student policy instead. The trap is what happens next: the moment you take a job (including a small side job under a work permit) or a paid internship, you become verzekeringsplichtig (insurance-obliged) from that start date, and you get four months to register Dutch basic insurance before penalties kick in. A lot of students don't realise their exemption ended the day their first paycheck landed, keep running on their old policy, and only find out when a letter from CAK — the body that cross-checks insurance status against tax and employer records — arrives months later demanding backdated premiums plus a fine. If your situation changes — job offer, paid internship, a scholarship structured as employment — check your obligation status that week, not at the end of the semester. Your university's student services office is a reliable first stop for confirming where you stand.
