should you detach your adult children?

A child: half a share. Two children: one full. Three children: Two shares… Income tax is calculated by dividing the household’s taxable income by the number of “tax shares” that make up the household. This is called the family quotient mechanism. Logically therefore, the higher the number of shares declared, the lower the amount of tax claimed from the taxpayer.

If the question is quickly decided when the children are minors, it becomes more complicated when they reach the age of majority, a fortiori when they themselves receive income. Is it then still financially wise to keep them in your tax household? Wouldn’t it be more interesting to ask them to do their own tax return? Here’s how to make the right choice based on your personal situation.
