After-tax income of economic family

Status: This standard was approved as a departmental standard on March 21, 2016.


After-tax income refers to total income less income taxes of the statistical unit during a specified reference period. Income taxes refers to the sum of federal income taxes, provincial and territorial income taxes, less abatement where applicable. Provincial and territorial income taxes include health care premiums in certain jurisdictions. Abatement reduces the federal income taxes payable by persons residing in Quebec or in certain self-governing Yukon First Nation settlement lands.

Economic family refers to a group of two or more persons who live in the same dwelling and are related to each other by blood, marriage, common-law union, adoption or a foster relationship. A couple may be of opposite or same sex.

By definition, all persons who are members of a census family are also members of an economic family. Examples of the broader concept of economic family include the following: two co-resident census families who are related to one another are considered one economic family; co-resident siblings who are not members of a census family are considered as one economic family; and, nieces or nephews living with aunts or uncles are considered one economic family.


When the mean, median or percentages are calculated for income, the units without income may be either included or excluded based on the analytic purpose. The units included in the calculation should be specified.

To facilitate comparison of income of persons not in families and families of different sizes or compositions, income can be adjusted using factors that account for the possibility of economies of scale for larger families. See 'adjusted after-tax income' in the Additional information section for more information.

Conformity to relevant internationally recognized standards

This standard does not correspond to the disposable income concept contained in the "Canberra Group Handbook on Household Income Statistics, Second edition". Unlike after-tax income, the disposable income concept accounts for social insurance contributions and other non-discretionary spending in order to measure income available for consumption and savings.


  • 'Amount of income' is expressed in Canadian dollars. The data presentation should specify any adjustments made, including whether the unit of measure is current dollars or constant dollars. Amount of income can range from the lowest negative number on the file to the maximum positive number on the file. October 15, 2012 to current


Additional information

In order to reduce response burden, many social statistics programs at Statistics Canada now gather information on income components and income taxes from administrative records from Canada Revenue Agency (CRA) to derive after-tax income. The after-tax income concept presented in this definition does not correspond to any income concepts used by CRA for tax purposes.
