For example, in France, the average gross salary is €3,270 per month, some €600 less than in Belgium. After calculating the various taxes, the French employee will receive an average of nearly €2,500 net monthly. In Belgium, the average gross salary is therefore €3832, the calculated net income is €2350.
In other words, 600 € gross more in Belgium, and yet 150 € less in your pocket than in France.
