The Federal Child Support Tables set out the basic monthly amounts of child support under the Federal Child Support Guidelines. The tables have been updated to reflect more recent tax rules. The updated tables came into effect on November 22, 2017. Use the 2011 tables to calculate child support for a period before that date.
The official legal version of the updated Federal Child Support Tables, as well as additional information about the amendments, are found in the Canada Gazette. The official version of the 2017 Federal Tables will also be available on the Department of Justice website shortly.
Tools to help calculate child support amounts include:
While you may find the simplified tables and the online look-up easier to use than the official Federal Tables, you should be aware that only the official version is a legal document. The simplified tables and the online look-up simply provide general information.
You should also be aware that the results you get using the simplified tables may not be exactly the same as the results you get using the online look-up or the official tables. That is because child support amounts in the simplified tables are based on incomes rounded to the nearest $100. But the results will be very close.
Before you use the tables, you may find it helpful to consult the Department of Justice Canada's publication called Federal Child Support Guidelines: Step-by-Step. This guide provides 8 easy steps to help you determine child support under the Federal Guidelines.
