@ABS25 If your partner is a cross-border worker (BE ->NL) you follow the same rights. As a result, you can also work as a cross-border worker in the Netherlands with your F-card. Your dutch employer doesnt need to apply for a work permit for you. You only need to apply for a BSN number (for tax registration). You also need a dutch health insurance besides of your Belgian one (which is quite costly). If your partner is not a cross-border worker I think the dutch employer needs to obtain a work permit for you. This is as far as my knowledge goes.
