Enter your guideline income and residence below. Guideline income is governed by section 15 of the Child Support Guidelines generally includes all income from all sources other than spousal support from the parent paying child support. As the Child Support Tables are province-specific, taking into consideration different provincial tax rates, the amount of child support payable may vary depending on each parent's province of residence.
