Cancelling your health insurance without a gap

Only let your Dutch health insurance end once your cover on the other side is arranged. There's one thing you never want on emigration: a period in which you're insured nowhere. The order is therefore:

• first the cover on the other side: work, an S1 form from the CAK or a policy of your own;
• only then the Dutch end date, which you preferably report to your insurer two months before departure.

An S1 form is the proof that you are also insured in your new country through your Dutch pension or benefit. You get it from the CAK.

A gap arises exactly for whoever treats health insurance as a subscription you cancel the way you cancel a newspaper. Dutch basic insurance is no subscription. It's tied to living or working in the Netherlands. The Dutch government puts it like this: "your personal situation determines whether you remain insured for medical costs in the Netherlands".

Which cover belongs to your situation?

First arrange your cover on the other side, and have the Dutch end date join it seamlessly. That's your departure day, not the first of the month that happens to be convenient.

Report your moving date to your health insurer, according to NederlandWereldwijd "preferably 2 months before departure" to avoid double costs. The insurer processes the end of the insurance obligation.

Which cover that is differs per situation. For Spain there are three routes, and which one applies to you, you already knew from the income and healthcare requirement:

• You're going to work in Spain, as an employee or self-employed. Then you fall under Spanish social security and are insured there. You don't have to insure anything extra. You do have to bridge the transition weeks until your contract starts.
• You're retired with a Dutch pension. Then you fall under the treaty arrangement and are "legally obliged to insure yourself for medical costs via the CAK". You register with the CAK before departure. It handles the application within at most four weeks and then sends you the S1 form, with which you register with healthcare in Spain. The treaty contribution, the premium you pay via the CAK, is usually withheld from your pension automatically. The amount depends on your income and your country of residence. And mind the date: as expected, from 1 November 2026 this route only remains open to new applicants with a statutory benefit: AOW, Anw, WAO, WIA or Wajong. With only early retirement or RVU you then fall under the route below.
• You don't work in Spain and aren't retired: you work remotely, or live off assets. Then you take out insurance yourself that covers all risks in Spain. That's not just sensible. It's literally what Real Decreto 240/2007, the Spanish decree on residence of EU citizens, sets as a condition for whoever stays longer than three months without work: sufficient means and "health insurance covering all risks".

A European Health Insurance Card (EHIC) is no emigration cover. That card is meant for temporary stays and hangs on your Dutch insurance, which is precisely what ends. Whoever "does the first year on the blue card" stands empty-handed at the registration appointment and is in fact uninsured.

Why does this have to happen before the deregistration?

Your insurance obligation doesn't end on the day your policy expires but on the day your situation changes. Your deregistration with the municipality is the visible moment of that. That means:

• Whoever deregisters without new cover has a gap.
• Whoever cancels their policy too early while still living in the Netherlands has a problem with the insurance obligation.

Remote work for a Dutch employer deserves its own warning. Where you're socially insured then depends on agreements between the countries, and that also determines your healthcare route. Have your employer look into this before your departure. The answer changes what you have to arrange.

Family members moving with you without a pension or benefit of their own you put on your own CAK application. Whoever does have a pension of their own registers separately.
