Citizens living and working in the Netherlands pay income tax varying between 33.5 % and 52% depending on their gross annual income.
It is the obligation of your employer to withhold this tax on your wage and to file the tax returns in this respect.
The Netherlands is in the top 3 of countries paying the highest taxes, which affects both employers and employees. However, The Netherlands also have an outstanding social security system. Expatriates (inter company transfers) can apply for a so-called 30 % tax ruling. This does not apply to non-Dutch speakers being recruited in The Netherlands
