Does Dutch or German labour law apply?
Unless otherwise specified in your employment agreement, the labour laws of the country in which you are employed apply.
In which country do I have to pay taxes?
If you work exclusively in Germany and earn more than € 400 monthly, it is more than likely that you have to pay your taxes in Germany.
Which taxes do I have to pay when I work in Germany?
As is the case in the Netherlands, in Germany, taxes are also deducted directly from your salary. If you work for an employer in Germany, he or she will withhold wage tax from salary payments.
