Minor child
You can deduct from your income, under certain conditions, the support you pay to support a minor child for whom you do not provide primary care.
The child is considered to be the primary responsibility (maintenance and upbringing) of the parent with whom he or she has his or her habitual residence.
The child should not be included in the calculation of your family quotient.

The pension was fixed by judgment
If there is a judgment, you have to deduct the amount of the pension set by the judge.
The amount to be deducted corresponds to the pension which may be revalued by a judgment or by yourself.
You can also deduct expenses in kind that you pay directly in addition to the maintenance initially set (canteen fees, school fees, medical expenses).
You cannot deduct the costs incurred by your right of access (e.g. travel costs).
FYI
in case of alternate guard after a divorce or separation, you cannot deduct a pension because you are entitled to an increase in your pension number of shares.
You must indicate the amount of pensions to be deducted on your return.
To complete your tax return, you can consult the explanatory note and the practical income tax brochure.
Supporting documents must be kept in case of request from the tax authorities.
Lack of judgment
You can deduct the pension you pay.
The amount paid must correspond to the execution of your maintenance obligation, i.e. the needs of your child and your financial means.
You must be able to justify your payments.
The expenses incurred by your right of access (travel expenses for example) are not deductible.

Adult child
You can deduct from your income, under certain conditions, the support you pay to support an adult child.
This is especially the case if your child is unemployed or looking for a 1er employment and that he has few or no resources.
Warning
your child must file his or her own tax return and cannot be connected to your tax home.
You can deduct support payments you make to an adult child if the following 2 conditions are met:
- Your child is not attached to your tax home for income tax purposes
- His income is inadequate
For example, it could be a pension for a child who is pursuing an education or who is unemployed.
The amount of the deduction is limited.
The deduction is a lump sum of €3,786 (double if your child is married or passed). It mainly covers expenditure on accommodation and food. You don't have to provide proof.
If you are only accommodating your child for part of the year, this amount is reduced in proportion to the number of months involved. If a month has elapsed, it is counted in full.
FYI
You must enter this deduction in the Deductible expenses on your tax return.
You can also deduct other expenses (such as tuition fees) for their actual and justified amount.
Total deduction cannot exceed €6,368 per child.
Please note
Your adult child must file his or her own return, in which he or she indicates the amount of income you pay to him or her.
To complete your tax return, see the explanatory note and the practical income tax brochure.
Keep receipts in case taxes ask for them.
