British Columbia Canadian Child Support Calculator

Child support in British Columbia is calculated using the Federal Child Support Guidelines (SOR/97-175) table system based on the paying parent's gross annual income and the number of children. The 2025 tables, effective October 1, 2025, provide fixed monthly amounts for incomes up to $150,000—for example, approximately $765 per month for one child at $80,000 income. Parents look up the paying parent's income in the British Columbia-specific table, which accounts for provincial tax rates, then add any applicable Section 7 special expenses shared proportionally by income.

Section 7 of the Federal Child Support Guidelines covers special or extraordinary expenses that parents share in addition to basic table support. In British Columbia, Section 7 expenses typically include childcare costs necessary for work or education, uninsured medical and dental expenses over $100 annually, health insurance premiums for the child, and post-secondary tuition. Extracurricular activities like competitive sports or music lessons may qualify if the court finds them necessary, reasonable, and affordable given the family's circumstances. Parents share these costs proportionally—if one parent earns 60% of combined income, they pay 60% of approved Section 7 expenses.

When each parent has parenting time with the child at least 40% of the year (approximately 146 days), British Columbia courts apply the set-off method under Section 9 of the Federal Child Support Guidelines. Each parent's table amount is calculated as if the other had sole parenting time, then the lower amount is subtracted from the higher. For example, if Parent A would pay $710 monthly and Parent B would pay $439, Parent A pays the $271 difference to Parent B. Courts also consider increased costs of maintaining two homes and actual spending on the children, following guidance from Contino v. Leonelli-Contino (2005 SCC).

British Columbia child support calculations start with gross income from Line 15000 (formerly Line 150) of the paying parent's most recent tax return or Notice of Assessment. However, courts may adjust this figure under Schedule III of the Federal Child Support Guidelines, which allows deductions for union dues, professional fees, and certain business expenses. For self-employed parents, courts may add back business deductions or impute income if they find underreporting. Corporate income, investment income, and RRSP withdrawals may also be included. If income fluctuates significantly, courts often average the last three years.

Yes, child support in British Columbia can be modified when there is a material change in circumstances, such as a significant income change, job loss, or change in parenting arrangements. Under Section 17 of the Divorce Act, either parent can apply to court to vary, rescind, or suspend a support order. British Columbia also offers the free Child Support Recalculation Service (CSRS), which annually reviews eligible orders and automatically adjusts support based on updated income information—reducing the need to return to court. Income changes lasting longer than six months are generally considered sufficient grounds for variation.

Child support in British Columbia generally continues until the child reaches age 19, the provincial age of majority. However, both the federal Divorce Act and BC Family Law Act define a dependent child as one who is 19 or older but unable to withdraw from parental support due to illness, disability, or another cause—including full-time post-secondary education. British Columbia courts routinely extend support for university or college students who demonstrate reasonable academic progress and continued financial dependence. The parent seeking continued support must provide enrollment confirmation, expense documentation, and evidence of any scholarships, loans, or employment income.

When a British Columbia parent's income exceeds $150,000, Section 4 of the Federal Child Support Guidelines applies. For the first $150,000, courts use the standard table amount. For income above that threshold, the court has discretion to determine an appropriate amount based on the children's condition, means, needs, and the parents' ability to contribute. British Columbia courts rarely deviate from table amounts unless income substantially exceeds $650,000. In J.A.T.P. v. H.M. (2023 BCSC), the court reduced support from $103,318 to $15,000 monthly for a $13 million earner because the table amount far exceeded the child's reasonable needs.

Extracurricular activities in British Columbia may qualify as Section 7 special or extraordinary expenses under the Federal Child Support Guidelines, but they must meet a three-part test: necessary, reasonable, and extraordinary. The expense must exceed what basic table support should ordinarily cover, be reasonable given the family's historical spending patterns, and be affordable based on the parents' financial circumstances. Competitive sports, elite music programs, and specialized training are more likely to qualify than recreational activities. When approved, parents share the cost proportionally based on their respective incomes—for example, a parent earning 65% of combined income pays 65% of the activity fees.
