If you have income or assets in both the Netherlands and Portugal, double taxation can be a complex issue. Fortunately, there is a bilateral treaty between the Netherlands and Portugal that prevents you from being taxed twice on the same income. This treaty determines which income is taxed in which country and often provides exemptions or credits.
