Nova Scotia Canadian Child Support Calculator

Child support in Nova Scotia is calculated using the Federal Child Support Guidelines (SOR/97-175) table amounts based on the paying parent's gross annual income and number of children. The table amount is determined by locating the paying parent's income in the Nova Scotia-specific tables updated October 1, 2025. This base amount may be adjusted by adding Section 7 special or extraordinary expenses, which parents share proportionally to their incomes.

Section 7 special or extraordinary expenses are costs paid in addition to the base table amount and include childcare, uninsured medical/dental expenses, post-secondary education costs, and extracurricular activities. Under Section 7(1) of the Guidelines, these expenses must be necessary in the child's best interests, reasonable given parental means, and consistent with pre-separation family spending patterns. Parents share Section 7 expenses proportionally to their respective gross incomes after deducting any contribution from the child.

When each parent exercises parenting time for at least 40% of the year (146+ days), Section 9 of the Federal Child Support Guidelines applies a set-off calculation. Each parent's table amount is calculated based on their income and the number of children, then the parent with the higher table obligation pays the difference to the other parent. The court also considers increased costs associated with shared parenting arrangements and each parent's means, needs, and circumstances when determining the final amount.

Nova Scotia child support calculations use the paying parent's gross annual income as shown on line 15000 of their Canadian income tax return. This includes employment income, self-employment income, investment income, rental income, and other taxable sources. The court may impute income if a parent is intentionally underemployed, unemployed without reasonable excuse, or fails to disclose income information fully.

Yes, child support can be modified if there is a material change in circumstances since the last order. Under Section 37 of the Parenting and Support Act, material changes include significant income increases or decreases for either parent, job loss, the child's changing needs or living arrangements, or children entering post-secondary education. Parents must apply to court for a variation order—child support orders do not change or terminate automatically.

Child support in Nova Scotia continues until at least age 19 (the provincial age of majority) and can extend beyond if the child remains dependent due to full-time post-secondary education, illness, or disability. Canadian courts routinely order child support for adult children attending college or university until completion of their first degree or diploma program. Child support obligations do not terminate automatically; the paying parent must apply to court to end support when the child becomes independent.

For income over $150,000, Section 4 of the Federal Child Support Guidelines requires the table amount for the first $150,000 plus an additional amount for the excess income. This additional amount is calculated either by multiplying excess income by the percentage shown in the Nova Scotia tables or by a court-determined amount based on the children's condition, means, and needs, plus each parent's financial ability to contribute. Section 7 special expenses may also be added to this total.

Extracurricular activities may qualify as Section 7 extraordinary expenses if they exceed what the table amount can reasonably cover. Under Section 7(1.1), courts assess whether activities are extraordinary by examining the expense relative to the recipient parent's income (including child support received), the nature and number of programs, the child's special needs and talents, and overall costs. If deemed extraordinary, parents share the expense proportionally to their incomes after deducting any contribution from the child.
