Where should I indicate expenses for a child who is not part of my tax household?
The allowance for child(ren) not forming part of the tax household can only be claimed when you no longer have custody of your child following a divorce/separation.
In the "Children" form, uncheck the box "The child was part of my household" and then indicate the annual amount of fees you have paid.
What can I deduct for a child who is not part of my tax household?
However, the allowance may not exceed €4,422 per year and per child. The taxx.lu system automatically applies this maximum.
