Income Tax - Child support paid to a parent or grandparent (deduction)

Verified 07 April 2022 - Legal and Administrative Information Directorate (Prime Minister)

You can deduct support payments to a parent from your income under certain conditions ascending who needs your help. Maintenance can take various forms.

You deduct income maintenance if it meets the following 3 conditions:

  • For ascending in need, to which you have maintenance
  • Limited to covering your parent's basic needs (food, accommodation, health...)
  • Proportionate to your resources, based on your expenses


you cannot deduct alimony if you receive tax reduction for employment of an employee at home of your ascendancy.

You can pay support in several ways:

  • Cash (checks, transfers...)
  • By paying in place of your parent various expenses (medical expenses, nursing home expenses...)
  • Accommodating your parent or providing them with accommodation

General case

If the conditions are met, you can deduct maintenance payments provided you can justify your payments (bank statements...) and the reality of the expenses incurred (invoices...).

The amount is not limited.

Example :

You pay €400 a month to your mother in need.

Maintenance is therefore €4,800 for one year.

This amount will be deducted from your total income by tax services.

The ascendant is hosted at your home

If the conditions are met, you can deduct a lump sum of €3,592.

If ascending at age 75, the conditions for the lump-sum deduction are considered to be met when the resources do not exceed the following ceilings (income 2021).
