One of the most common points of confusion for new arrivals in the Netherlands is whether they need to take out Dutch health insurance (the basisverzekering) or whether they can use their existing international or private health insurance. The answer depends primarily on your employment situation and your nationality, and getting it wrong can result in fines, gaps in coverage, or overpaying for insurance you do not need.
Who must take out Dutch health insurance
You are required to take out Dutch health insurance (basisverzekering) if you live and/or work in the Netherlands and are subject to Dutch social security legislation. In practice, this means: if you work for a Dutch employer or for a foreign employer in the Netherlands, you are insured under Dutch social security and must take out Dutch health insurance. There is no opt-out. The obligation begins on your first working day or your registration as a resident, not after a waiting period.
Who may be exempt
There are a few categories of expats who may not be required to take out Dutch insurance. If you are posted to the Netherlands by an employer in another EU/EEA country for a limited period and hold an A1 certificate confirming you remain subject to your home country's social security, you are generally not required to take Dutch insurance. Some diplomatic and consular staff are also exempt. If you are posted by a non-EU employer and your home country has no social security agreement with the Netherlands, the situation is more complex and legal advice is recommended.
The case for Dutch basic insurance
For the vast majority of expats — those working for Dutch employers or on local contracts — Dutch basic insurance is not only mandatory but also genuinely good value. The Dutch healthcare system is high quality. You have the right to access any GP or specialist in the Netherlands. The administrative infrastructure (electronic prescriptions, referral systems, specialist networks) is built around the Dutch insurance system, which means if you have foreign insurance, the practical experience of accessing care can be significantly more complicated.
The case for private international insurance
If you are genuinely exempt from Dutch social security (for example, under an A1 certificate), private international health insurance has some attractions: it often provides broader coverage including dental, better private hospital accommodation, and easier access to healthcare in your home country if you travel frequently. Plans from providers like Cigna Global, Aetna International, or Allianz Care are designed for internationally mobile professionals and offer global coverage that a Dutch basisverzekering does not.
However, if you are required to take Dutch insurance and also maintain private international insurance, you are essentially paying twice for overlapping coverage. In this scenario, keeping your private insurance as a top-up for dental, vision, and international emergency care — while using the Dutch basic insurance for your day-to-day Dutch healthcare needs — is usually the most rational approach.
A common mistake
The most common mistake we see is expats arriving with good international private insurance from their previous country or employer, assuming it covers them in the Netherlands, and not registering for Dutch insurance. The Belastingdienst will eventually catch this, and the fine plus backdated premiums can be substantial. If in doubt, contact the SVB (Sociale Verzekeringsbank) to confirm your social insurance status before making a decision about health insurance.
Supplementary insurance from Dutch insurers
Most Dutch insurers offer supplementary packages (aanvullende verzekeringen) that add dental, physiotherapy, glasses, and other coverage on top of the basic package. These vary considerably in price and value. If you have specific healthcare needs — regular physiotherapy, contact lenses, or ongoing dental treatment — it is worth comparing supplementary options carefully using tools like Zorgwijzer.nl. A basic dental supplementary package typically costs €15–€30 per month and covers a meaningful percentage of dentist costs above what the basic insurance provides.
