General case
A child under the age of 18 is counted as dependent on his or her parents.
For the 2023 income tax return for 2022, if your child was born in 2004 or later, it will be considered dependent on you.
Each dependent child shall be entitled to an increase in the number of shares of family quotient.
It lowers your tax.
Child | Number of additional shares |
---|---|
1er child | 1/2 share |
2e child | 1/2 additional share |
From 3e child | 1 additional share per child |
Please note
when the burden of a child is shared equally between its two cohabiting parents, each can benefit from half of the increase in shares (as for a alternate custody child).
If the minor child has his or her own income, you must add it to your income. Your children are always considered your dependants.
Child declaring income
If your minor child has personal income, you can apply for separate taxation.
Your child must have personal income from his or her own work or personal property.
When you ask for a separate tax, the child ceases to be dependent on you.
The request for separate taxation must be made on free paper, attached to your tax return.
Your child must declare his income himself.
FYI
once claimed, the separate taxation shall cover the whole year.
