Income Tax - Dependent Child

Verified 08 avril 2021 - Legal and Administrative Information Directorate (Prime Minister)

Your minor children are considered to be your dependants. However, in certain situations, specific rules apply. For example, if your child reaches the age of majority during the year or you have separated.

General case

A child under the age of 18 is supported by his parents.

For the 2020 income tax return, if your child was born in 2002 or later, he or she will be considered dependent.

Each dependent child is entitled to an increase in the number of family quotient shares, thus reducing your tax.

Number of shares of family quotient per child


Number of additional shares

3to child

3/2 share

2e child

3/2 additional share

From 3e child

1 additional share per child

  Please note : when the burden of a child is shared equally between the two parents, everyone can benefit from half the quotient.

If the minor child has own income, you must add it to your income. Your children are then always considered to be in your care.

Child reporting personal income

If your minor child has personal income, you can claim a separate tax.

Your child must have personal income from his or her own work or personal property.

When you request a separate tax, the child ceases to be considered dependent.

The separate tax claim must be on free paper attached to your tax return.

  FYI : once claimed, the separate tax covers the entire year.

2020 for children

A young person who reaches the age of majority in the tax year can remain dependent on you or make his or her own return.

You can still count your dependent child as a minor child. You can benefit from a share increase for the whole year.

You must add to your income those your child has disposed of of of 1to January on the date of his majority.

The young person must file his own return for his income from the date of his majority until December 31.

Child is attached to your tax home

Your child can ask for linking to your tax home for the whole year. He must write this application on free paper and sign it. He has no personal statement to subscribe to.

You must declare your dependent child on your tax return and report your child's income for the full year. You can benefit from the increase in the family quotient.
