What Happens If You Don't Have Health Insurance in the Netherlands?
No zorgverzekering in the Netherlands? You risk fines, retroactive premiums, and CAK enforcement. Here's exactly what happens and how to fix it.
Dutch law is clear: if you live and work in the Netherlands, you must have health insurance (zorgverzekering). No exceptions for expats, no grace period beyond the initial four months after registration. If you let your insurance lapse — or never got it in the first place — there are real consequences.
Here's exactly what happens, who enforces it, and how to fix it.
Who Is Required to Have Health Insurance?
Every person who lives or works in the Netherlands and is registered in the population register (Basisregistratie Personen, BRP) must hold a valid Dutch basisverzekering (basic health insurance policy).
This includes:
- Dutch citizens
- EU/EEA citizens living or working in the Netherlands
- Non-EU expats with a valid residence permit
- Anyone employed by a Dutch employer, even if living abroad
Who is exempt:
- Tourists and visitors on short stays
- People covered by a home-country policy under EU coordination rules (e.g., cross-border workers)
- Some diplomats and international civil servants
If you're unsure whether you're obligated, check with the CAK or your municipality.
The Timeline: What Happens After You Miss Coverage
Step 1: The Warning Letter
The Centraal Administratie Kantoor (CAK) is the Dutch government body responsible for enforcing health insurance compliance. They cross-reference the BRP with insurer databases regularly.
If you appear in the BRP without an active insurance policy, the CAK sends you a written warning. This gives you 3 months to get insured.
Step 2: Forced Enrollment at a Penalty Premium
If you don't respond to the warning and get insured within 3 months, the CAK takes action:
- They enroll you in a health insurance policy automatically, with a randomly assigned insurer.
- They charge you a penalty premium: approximately 130% of the standard monthly premium for every month you were uninsured — retroactively.
In 2026, the standard premium averages around €135–€160/month. The penalty premium comes to roughly €175–€210/month — for every month you were uninsured, including months before you received the warning.
Step 3: Debt Recovery
If you don't pay, the CAK escalates to debt recovery. This can include:
- Referral to a collection agency
- Salary garnishment (if you have a Dutch employer)
- Benefit seizure (if you receive Dutch benefits)
The CAK can also add administrative costs on top of the outstanding amount.
Real Cost Example
Suppose you moved to the Netherlands in January 2026, registered with your gemeente, but forgot to arrange health insurance. In October 2026 (9 months later), you receive a CAK warning. You ignore it. By January 2027:
- Uninsured months: 12
- Penalty premium (estimated): €185/month × 12 = €2,220
- Administrative fees: additional
- Forced insurer: random, possibly not your preferred provider
That €2,220 must be paid on top of your ongoing premiums going forward.
What About a Lapsed Policy?
If you had insurance and your policy lapsed (e.g., you stopped paying premiums and were dropped by your insurer), the same rules apply. The CAK monitors for gaps — even short ones.
Contact your insurer immediately if you've missed payments. Most insurers have a reinstatement process, and it's far cheaper to reinstate than to let a gap trigger CAK enforcement.
How to Fix It: Getting Insured After a Gap
Step 1: Act immediately. Every additional month uninsured adds to your retroactive liability.
Step 2: Choose an insurer and sign up. All Dutch insurers must accept you for the basic package (basisverzekering) — they cannot refuse you based on age or health history.
Step 3: Notify the CAK once you have a policy start date. This stops the penalty clock.
Step 4: Respond to the CAK about the retroactive period. You will likely owe a surcharge for the months you were uninsured. If you cannot pay it all at once, request a payment plan.
Step 5: Check if you qualify for zorgtoeslag. If your income is under approximately €38,500 (single, 2026), you may be entitled to a monthly healthcare subsidy that reduces your ongoing premium cost significantly. Apply at mijntoeslagen.nl.
How to Avoid This Entirely
The simplest rule: get insured within 4 months of registering in the Netherlands.
If you're just arriving:
- Register with your municipality (gemeente) — this puts you in the BRP.
- Within 4 months, choose a health insurer and sign up.
- Coverage begins from your registration date (retroactively), so there's no gap.

If you're already insured, set up automatic payment for your premium so it doesn't lapse due to a missed bank transfer.
The Bottom Line
Not having Dutch health insurance is not a gray area — it's a legal violation with financial penalties enforced by the CAK. The good news: once you're insured, the problem stops growing. The bad news: the CAK will chase retroactive charges even years later.
If you're uninsured right now, today is the day to fix it.
