Mini-job
A mini-job (€ 450) in Germany is a part-time job that is not subject to insurance. This means that a resident of the Netherlands has no health insurance at all. If you still have a mini-job, you must take out voluntary health insurance with a German health insurance company. This entitles you to Dutch health insurance and WLZ (long-term care insurance) in the Netherlands. You should be aware that you will not be entitled to a ‘zorgtoeslag’ [health insurance supplement] from the Dutch tax office. In addition, you will only accrue a very small AOW pension in the Netherlands.
If you have a job that is subject to compulsory insurance (you earn more than € 450 gross per month), you will find all the information you need under ‘Working in Germany from the Netherlands‘.
