Yes, but will some differences :
1. Say you make € 20,000 a year.
2. Say The income tax is 38%
3. You have to pay € 7600 in tax
4. Pay that tax on a monthly basis ( income tax)
5. If you have one child, you will receive approx. €750 / year ( non-taxable)
6. Net income approx € 13150
This rule was valid till 2004, but with the additions of new countries to the EU
rules have changed.
Still in Luxembourg, they pay you high Child allowances ( and low income tax)
which may result in a very high net income related to the bruto income.
