Healthcare benefit is a contribution to the costs of your healthcare contribution. Whether you receive a healthcare benefit depends on your income and that of your partner. You apply for a healthcare benefit from the Tax Administration in the Netherlands. The Tax Administration also takes into account the country of residence factor. If you live in a country with a low country of residence factor, you are unlikely to be entitled to a healthcare benefit.
See the website of the Tax Administration
(Belastingdienst.nl) for the conditions and more information.
Co-insured children aged 18 and over can apply for a healthcare benefit independently.
