The Canada child benefit (CCB) is a tax-free monthly payment made to eligible families to help them with the cost of raising children under 18 years of age. The Canada Revenue Agency uses information from your income tax and benefit return to calculate how much your CCB payments will be. To get the CCB, you have to file your return every year, even if you did not have income in the year. If you have a spouse or common-law partner, they also have to file a return every year.
