Dutch health insurance — the four-month deadline, liability, and what the basic package misses
Four months from arrival to take out Dutch cover, and holding an excellent policy from home is not an exemption. The people who miss it are rarely the careless ones.
What the Netherlands requires
Simple to satisfy, expensive to be late for.
There is no complicated specification here and no visa threshold to clear. There is a deadline, a liability test that is easy to get wrong, and a bill that is backdated.
A four-month clock starts on arrival
Once you are subject to Dutch social security you must take out the basic Dutch package, the <em>basisverzekering</em>, within four months. The clock runs from your residence permit, or from registering at the town hall if you are an EU, EEA or Swiss national. Nobody sends a reminder.
Your foreign policy does not stop it
Holding excellent international cover is not an exemption. If you are liable, you are liable — and people carrying comprehensive policies from home are exactly the group most likely to assume otherwise and let the four months pass.
And the state signs you up itself
The CAK's enforcement ladder, verified 2026-08-01 against its own pages: a €529.74 fine (2026) if you are uninsured three months after their letter, a second €529.74 three months later — and then the CAK takes out insurance FOR you, at the standard premium of €172.70 a month, withheld from your salary or benefits for twelve months. The state does not give up. It signs you up and sends the bill to your payroll.
Which is why this page is short on rules and long on timing. Nothing about the Dutch requirement is hard. Being late for it is the only expensive part.
The clock, dated
Four months, two fines, then the state acts.
The Dutch year as a sequence of deadlines — with the enforcement ladder verified against the CAK's own pages (2026-08-01). ⚑ marks the trigger wording still pending.
Before you arrive · establish liability, on paper
The Dutch question is not "am I insured" but "am I liable" — and liability follows work, residence and social security, not the quality of the policy you hold. ⚑ The four-month window's exact trigger points (permit vs town-hall registration) still rest on secondary wording; the obligation itself does not.
Your first fortnight · settle it, both directions
Being liable and late is expensive; taking the basisverzekering when you are NOT liable means paying twice for nothing. Both mistakes are real. An afternoon with the SVB's Wlz assessment, or an adviser, settles which side you are on — spend it in week two, not month four.
Inside the window · choose, then layer
The basisverzekering is a legal minimum with a compulsory excess and real gaps — adult dental and physiotherapy first among them. Choose the insurer on service and the excess level on your own arithmetic, then decide which gaps are worth insuring rather than paying for.
If the letter comes · the CAK ladder, exactly
Verified against the CAK's own pages: a €529.74 fine (2026) if you are uninsured three months after their letter, a second €529.74 three months later — then the CAK takes out insurance FOR you at the standard premium, €172.70 a month, withheld from salary or benefits for twelve months.
If you leave or your status changes · deregister properly
Liability ends the way it began: with your situation, not your intentions. Ending Dutch employment or residence without ending the policy — or the reverse — creates exactly the kind of mismatch the CAK's systems exist to find. Close the loop the same week the status changes.
What the basic package does
A competent floor, with real gaps.
Dutch healthcare is strong and the basic package is a genuinely good product. It is not a grudging minimum in the way some national schemes are, and most residents need very little beyond it.
It does carry a compulsory excess, and it does leave gaps — adult dental and physiotherapy are the two people meet first. Supplementary cover exists for exactly those, and it is cheap enough that the decision deserves ten minutes rather than an afternoon.
The narrow question is worth asking out loud: what do you actually use that the basic package does not cover, and is that worth insuring or simply worth paying for? For a lot of people the honest answer is the second one.
And the mistake runs both ways. Taking the Dutch package when you are not liable means paying twice for nothing — which is why establishing liability comes before choosing a policy, not after.
| Stage | The rule | The note that matters |
|---|---|---|
| The obligation | Basisverzekering within four months of liability | ⚑ trigger wording pending; the duty itself is not in doubt |
| Your foreign policy | Not an exemption | liability follows your situation, not your cover |
| Fine no. 1 | €529.74 (2026) | three months after the CAK’s letter — verified on the CAK’s own pages |
| Fine no. 2 | €529.74 again | three months later, if still uninsured |
| The endgame | CAK signs you up itself | €172.70/month withheld from salary or benefits for twelve months |
| What the basic package leaves out | Adult dental, physiotherapy, the excess | ⚑ excess figure pending a primary source; the gaps are structural |
The fines and the compulsory sign-up are the CAK\u2019s own figures. The correction from an earlier version of this page: the endgame is not backdated premiums — it is the state signing you up and sending the bill to your payroll.
Who this page is for
Four situations, four different checks.
The posted employee with employer cover from home
Your excellent foreign policy does not answer the Dutch question. If Dutch social security applies to you, so does the insurance duty. Establish liability in writing in your first fortnight — the four months run while you settle in.
The EU freelancer registering at the town hall
Registration is commonly the moment liability begins for EU nationals. Do not treat the four months as thinking time: price the basisverzekering the same week you register, and choose your excess deliberately.
The researcher or student, possibly not liable
Some non-working arrivals fall outside Dutch social security — and taking the basic package anyway means paying for nothing. Get the liability answer from the SVB before buying, not from a forum.
The person who already got the CAK letter
The ladder is now verified and it does not stop: two fines of €529.74, then compulsory sign-up at €172.70 a month from your salary. Taking out insurance yourself today is strictly cheaper than every alternative. Do it before the second letter.

Dearer than Netherlands on this measure: Vietnam and Norway. Cheaper: India and Egypt.
The Netherlands is one of the cheapest countries in the whole index for comparable international cover, at about $6,740. A detail worth noticing: the Dutch and Norwegian figures for the 50-year-old persona are identical to the cent. That is regional zone pricing showing through — several carriers quote by zone rather than by country, so where an insurer draws its map can matter more than which side of a border you live on.
One thing the index is not, and its authors say so twice: it does not compare the seven insurers against one another. Where two of them price the same country differently, that reflects different benefits, cover areas and networks — not one being better value. And none of these figures is a quote. They are averages for three people who do not exist, and what you would actually pay turns on your age, your health, your family and where you want to be treated.

All fifty countries, and what the ranking hidesIn the Netherlands specifically
Three ways this goes wrong, and all three are avoidable.
Assuming your existing cover exempts you
It is the single most common way this goes wrong, and it happens to careful people. A good international policy feels like the answer to "am I insured", and the Dutch question is different: are you <em>liable</em>. Liability follows your situation — work, residence, social security — not the quality of what you already hold.
Waiting to see whether you are liable
The four months are not thinking time; they are a deadline, and it runs while you are finding a flat and starting a job. Establish liability in the first fortnight and act on it. If it turns out you are not liable, you have lost nothing but an afternoon — and taking the basic package when you are <em>not</em> liable is its own, quieter mistake.
Taking the basic package and stopping there
The <em>basisverzekering</em> is a legal minimum with a compulsory excess and real gaps — dental for adults and physiotherapy among them. It is a competent floor, not a finished plan. The question worth ten minutes is narrow: what do you actually use that it does not cover, and is that worth insuring or simply paying for?

How a review works
What a first review actually looks like.
Arranging international cover for the first time, or checking what you already hold — the process is the same, in this order.
The demand intake
Right after you book, we email you a short intake form. Where you are, where you're going, who's coming with you, anything you already hold. It takes a few minutes, and it means the 45 minutes start prepared — with your situation, not with paperwork.
We study your situation
Not products first. Your life first. We look at the country you're moving to and what it legally requires, the country after that if there is one, who depends on you, and where the real exposure sits. We don't quote anything at this stage.
The consultation
45 minutes, by video, in English. Every question you bring gets an answer. We compare the international insurers on how each of them behaves in your situation — underwriting, renewal, exclusions, and what happens on the day a claim is filed. If there is already a policy in force, we go through it clause by clause. Nothing is pitched at the end of it.
Your Private Client Report
One working day later, your Private Client Report arrives — around twelve pages setting out what we found, what we weighed it against, what each option costs, and why we would choose one over the others. What to arrange, what to keep, and where you are paying for something that isn't doing any work. Sometimes the report says: keep what you have. It is yours either way.
45 minutes. By video, wherever you are. Free. Nothing has to change afterwards.
The Cleveland Clinic charges $1,690 for a written second opinion. Ours comes with the review, and there is no fee for it.
The team
The people who'll actually review your situation.
Specialists by topic, not a rota. You'll know who you're speaking to before you book, and you'll speak to the same person again next year.

Book with HansNetherlands questions
What people actually ask us about the Netherlands.
Do I need Dutch health insurance if I already have international cover?
If you are liable under Dutch rules, yes — an existing foreign policy does not exempt you. This catches out well-prepared people more than anyone else, because good cover feels like a complete answer. The Dutch question is not whether you are insured but whether you are liable, and that follows your work and residence situation.
How long do I have to arrange it?
Four months from the point you become subject to Dutch social security — your residence permit, or town hall registration for EU, EEA and Swiss nationals. It is a deadline rather than a grace period, and it runs while you are doing everything else that moving involves.
What happens if I miss the deadline?
The CAK's enforcement ladder, from its own pages (verified 2026-08-01): a fine of €529.74 if you are still uninsured three months after their letter, a second €529.74 three months later — and then the CAK takes out insurance on your behalf at the standard premium (€172.70 a month in 2026), withheld directly from your salary or benefits for twelve months. Being late never costs less than being on time.
What does the basisverzekering not cover?
It carries a compulsory excess and leaves real gaps — adult dental and physiotherapy are the ones people meet first. Supplementary cover exists for exactly these. Whether it is worth buying depends on what you actually use, which is a shorter conversation than most people expect.
I am not sure whether I am liable. What should I do?
Settle it in your first fortnight rather than your fourth month. Liability turns on your work and residence situation, not your nationality or the policy in your drawer, and both mistakes are real: being liable and late is expensive, and taking the Dutch package when you are not liable means paying twice for nothing.
How much does international health insurance cost in the Netherlands?
Comparable international private medical insurance in the Netherlands costs about $6,739 a year on average, which ranks the Netherlands 44th of the 50 countries in the SIP Health Cost Index 2025 (data as at August 2025). That is an average across 7 international insurers and three standard profiles — a 24-year-old, a 35-year-old and a 50-year-old — so it describes what the country costs rather than what you would pay. Norway prices higher and India lower. Your own premium depends on your age, your health history, whether you are insuring a family, your deductible, and whether you need cover in the United States.

Where these facts come from.
The enforcement ladder is primary-verified with exact figures from the CAK's own pages — and it corrected us: an earlier version of this page said the premiums were backdated to arrival. The real mechanism is stranger and stricter: two fines, then compulsory insurance at the standard premium, withheld from your income for twelve months. The four-month window's exact trigger wording remains ⚑ pending.
