Quebec child support payments are calculated using the province's unique income-shares model, where both parents contribute based on their combined disposable income—not just the paying parent's income as in other Canadian provinces. For 2026, each parent deducts $13,575 from their gross income before calculation, and the Basic Parental Contribution Table (updated January 29, 2026) determines the total annual support obligation. A Quebec family with combined disposable income of $80,000 and one child typically owes approximately $7,200 annually in basic child support, divided proportionally between parents based on their respective incomes and parenting time arrangements.

How the Quebec Child Support Model Works
Quebec operates the only provincial child support system in Canada that replaces the Federal Child Support Guidelines entirely for intra-provincial cases. Under the Regulation respecting the determination of child support payments (C-25.01, r. 0.4), approximately 95% of Quebec child support cases use the provincial model, with federal guidelines applying only when one parent resides outside the province. The Quebec model requires completion of Schedule I (Child Support Determination Form) and consultation of the Basic Parental Contribution Table, which was last updated on January 29, 2026, to determine how much is child support Quebec parents must pay or receive.
The fundamental difference between Quebec and all other Canadian provinces lies in the income-shares approach. While the Federal Child Support Guidelines calculate support based solely on the paying parent's income, Quebec requires both parents to contribute proportionally to their combined disposable income. This means a parent earning $60,000 annually pays their proportional share of the total support obligation, not a fixed amount from a federal table.
Step-by-Step Calculation Process
Quebec child support calculation follows five distinct steps that determine how much is child support in Quebec for your specific situation:
- Calculate each parent's gross annual income from all sources including employment, self-employment, rental income, and investment returns
- Subtract the basic deduction ($13,575 in 2025, indexed to approximately $14,009 for 2026) from each parent's gross income to determine disposable income
- Add both parents' disposable incomes together to find the combined disposable income
- Consult the Basic Parental Contribution Table to find the total annual child support amount based on combined income and number of children
- Divide the total proportionally between parents based on their respective shares of combined income and adjust for parenting time arrangements
Quebec Basic Parental Contribution Table Amounts
The Basic Parental Contribution Table is the authoritative reference for determining child support amounts in Quebec. Updated most recently on January 29, 2026, with a 3.2% indexation increase, the table covers combined parental disposable incomes up to $250,000 CAD. These amounts represent the total annual contribution both parents collectively owe for their children's nine recognized essential needs: food, lodging, communications, housekeeping, personal care, clothing, furniture, transportation, and recreation.
| Combined Disposable Income | 1 Child | 2 Children | 3 Children |
|---|---|---|---|
| $30,000 | $3,240 | $4,860 | $5,940 |
| $50,000 | $5,100 | $7,650 | $9,350 |
| $80,000 | $7,200 | $10,800 | $13,200 |
| $100,000 | $8,400 | $12,600 | $15,400 |
| $120,000 | $9,480 | $14,220 | $17,380 |
| $167,000 | $11,760 | $19,440 | $23,760 |
| $200,000 | $13,200 | $21,780 | $26,620 |
Note: These are approximate 2026 amounts based on indexed 2025 table values. Always verify current amounts using the official Quebec government calculation tool or the PDF tables available at quebec.ca. Filing fee and table amounts as of January 2026. Verify with your local clerk.
How Parenting Time Affects Child Support Amount
Parenting time is the single largest variable affecting the final child support amount in Quebec, with three distinct calculation divisions under the Regulation. The amount of time each parent spends with the child directly impacts the support calculation, creating significant differences in payment amounts based on parenting arrangements.
Division 1: Sole Parenting (60%+ with One Parent)
When one parent has the child more than 60% of the time (approximately 219+ days annually), the non-primary parent pays their proportional share of the basic parental contribution to the primary parent. For example, if the basic contribution is $7,200 annually and the non-primary parent earns 55% of the combined income, they would pay $3,960 annually ($330 per month) to the primary parent.
Division 1.1: Extended Parenting Time (20-40% with Non-Primary Parent)
When the non-primary parent has between 20% and 40% parenting time (73-146 days annually), a reduced calculation applies. Quebec courts recognize that the non-primary parent incurs direct childcare expenses during their parenting time, warranting a reduction in the child support transfer payment. This division typically reduces child support obligations by 15-25% compared to Division 1.
Division 3: Shared Parenting (40-60% Each Parent)
Quebec defines shared parenting time as 40-60% with each parent, requiring a distinct calculation method. Under shared parenting, both parents calculate what they would pay as if they were the sole paying parent. The parent with the higher calculated amount pays the difference to the other parent. For two parents with equal 50/50 parenting time and equal incomes, the child support payment may be zero, as each parent bears their direct expenses during their parenting time.
Additional Child Support Expenses Beyond Basic Amounts
Quebec child support includes provisions for additional expenses beyond the basic parental contribution table amounts. These special expenses are added to the child support amount and divided between parents proportionally based on their share of combined disposable income. Understanding these additions is essential for determining the true child support amount Quebec parents actually pay.
Child Care Expenses
Child care costs include daycare fees, before and after school care, and summer camp expenses required for the primary parent to work or attend school. Quebec's subsidized daycare system (at $8.85 per day in 2026 for eligible families) significantly reduces these costs compared to other provinces, but private daycare can cost $1,200-$2,000 monthly. These expenses are added on top of basic child support and divided proportionally.
Post-Secondary Education Expenses
Net post-secondary education expenses include tuition fees, textbooks, required materials, and necessary transportation, food, or housing costs for students attending CEGEP or university. Quebec courts subtract any student loans, bursaries, scholarships, or tax credits from these expenses before calculating the parental contribution. Average CEGEP tuition is $0 for Quebec residents (general program), while university undergraduate tuition averages $3,500 annually.
Special Expenses for Particular Needs
Special expenses may include medical treatments not covered by RAMQ (Quebec's public health insurance), orthodontics ($4,000-$8,000 typical), private school tuition ($15,000-$30,000 annually for elite schools), tutoring services ($50-$100 per hour), and extracurricular activities such as competitive sports or music lessons. Courts assess whether special expenses are reasonable in light of the needs and abilities of each party.
Revenu Quebec Support Payment Collection Program
Quebec has a unique automated enforcement system that sets it apart from all other Canadian provinces. The Revenu Quebec Support Payment Collection Program (Programme de perception des pensions alimentaires) handles child support collection for all Quebec orders automatically, with over 87% of child support payments flowing through this program using direct employer deductions and bank debits.
Automatic Wage Deduction Process
Under the Act to facilitate the payment of support (CQLR c. P-2.2), Revenu Quebec automatically registers child support orders and initiates employer wage deductions within 30-60 days of the order being issued. Approximately 70% of Quebec child support payments are collected through automatic wage deduction, with employers legally obligated to remit payments directly to Revenu Quebec. Recipients receive payments twice monthly, on the 1st and 16th of each month, via direct deposit or cheque.
Self-Employment and Alternative Collection
For self-employed parents where wage garnishment is not feasible, Revenu Quebec employs alternative collection measures including levying bank accounts, seizing income tax refunds, and intercepting GST/HST credits. These measures ensure that self-employed parents cannot evade child support obligations simply by lacking a traditional employer.
Consequences of Non-Payment
Quebec enforces child support obligations aggressively, though with one notable exception: unlike other provinces, Quebec cannot suspend driver's licenses for non-payment (along with New Brunswick, the only two provinces without this power). However, Revenu Quebec can petition for denial or suspension of Canadian passports and federal marine and aviation licenses under the Federal Family Orders and Agreements Enforcement Assistance Act (FOAEAA). Persistent non-payers may face seizure of bank accounts, garnishment of investment income, and court contempt proceedings.
When Child Support Ends in Quebec
Quebec child support does not automatically terminate when a child turns 18. Under the Civil Code of Quebec, art. 585-586, parents must provide for children who cannot meet their own needs, including adult children pursuing full-time education. This obligation continues until the child achieves financial independence, not merely the age of majority.
Adult Children in Post-Secondary Education
Quebec courts consistently hold that child support continues for adult children attending CEGEP or university full-time, recognizing that higher education is essential for long-term financial stability. Support typically continues through the completion of a first undergraduate degree, though it may extend for professional or graduate programs in appropriate circumstances. The child must demonstrate diligent academic progress, with courts expecting students to maintain reasonable grades and complete their programs within standard timeframes.
The Rule of Thirds for Working Students
When adult children earn part-time income while remaining financially dependent, Quebec courts typically apply the "rule of thirds." Under this principle, one-third of the adult child's declared revenue is subtracted from the basic parental contribution. For students earning more than $5,000 annually, courts may apply 50% of their income rather than one-third. This approach ensures that working students contribute proportionally to their expenses while parents continue to provide support.
Termination Conditions
Child support in Quebec ends when the child achieves financial independence through full-time employment, voluntarily abandons education without pursuing other means of self-sufficiency, marries or enters a civil union (transferring support obligations to the spouse), or permanently leaves the family home without continuing education. Parents seeking to terminate support must demonstrate that the child is no longer "unable to meet their own needs" under Civil Code art. 585.
Modifying Child Support Payments
Quebec law permits modification of child support whenever a significant change occurs in the child's life, the payer's life, or the recipient's life. Under Civil Code of Quebec, art. 594, either parent may apply to the court for a variation at any time without waiting for a specific period to elapse. Common grounds for modification include job loss, income changes of 10% or more, changes in parenting time arrangements, a child starting CEGEP or university, and changes in the child's needs such as new healthcare or education expenses.
SARPA: The Low-Cost Alternative to Court
Quebec's Child Support Recalculation Service (SARPA) offers an affordable alternative for simple income-based modifications. For a fee of just $57.25, SARPA recalculates child support based on updated income information without requiring a court appearance. SARPA processes approximately 8,000 adjustment applications annually, resolving most within 45 to 60 days. However, SARPA can only handle income-based changes; modifications involving parenting time changes, addition of special expenses, or income calculation disputes must proceed through the court system.
When Court Proceedings Are Required
Even when parents agree on a new child support amount, court approval (called "homologation") is required to make the agreement legally enforceable. Parents must file their agreement with the Superior Court of Quebec, pay the applicable filing fee ($108 for joint applications), and obtain a court judgment approving the modified amount. Without homologation, Revenu Quebec cannot enforce the new payment amount, and the original court order remains in effect.
Tax Treatment of Quebec Child Support
Child support in Quebec is completely tax-neutral under orders or agreements made after April 30, 1997. Recipients do not report child support as taxable income, and payers cannot deduct child support payments from their taxable income. This "non-taxable, non-deductible" treatment applies to all child support orders under the Income Tax Act § 56.1(3), known as the "child support priority rule."
Child Support Priority Rule
When a Quebec order combines child support and spousal support, the CRA applies the child support priority rule. For example, if an order requires $2,400 monthly ($1,600 child support plus $800 spousal support) and the payer only pays $2,000 one month, the CRA treats $1,600 as child support first and only $400 as spousal support. This prevents payers from claiming larger deductions by shorting child support to maximize spousal support deduction claims.
Pre-1997 Orders
Child support orders made before May 1, 1997, follow the old "taxable-and-deductible" system unless converted using CRA Form T1157. Over 142,000 Canadians have used Form T1157 since 1997 to convert legacy orders to the tax-free regime. This election is irrevocable once made, so parents should carefully evaluate the tax implications before filing.
Canada Child Benefit Impact
The Canada Child Benefit (CCB) provides tax-free monthly payments to eligible families with children under 18. For the July 2025 to June 2026 payment period, families with adjusted family net income below $37,487 receive $666.42 monthly per child under 6 ($7,997 annually) and $562.33 monthly per child aged 6-17 ($6,748 annually). Child support received does not count as income for CCB calculation purposes, preserving full benefit eligibility for recipient parents.
Quebec vs. Federal Child Support Guidelines
Quebec is unique in Canada for having its own provincial child support model that applies to most family law cases within the province. Understanding when Quebec rules versus federal rules apply is essential for determining the correct child support amount.
| Factor | Quebec Provincial Model | Federal Guidelines |
|---|---|---|
| When Applied | Both parents in Quebec | One parent outside Quebec |
| Income Considered | Both parents' incomes | Paying parent only |
| Basic Deduction | $13,575 per parent (2025) | None |
| Parenting Time Impact | Three divisions with varying formulas | Shared custody offset at 40%+ |
| Percentage of Quebec Cases | ~95% | ~5% |
| Table Maximum | $250,000 combined | $150,000 individual |
| Special Expenses | Added after basic contribution | Section 7 expenses |
When Federal Guidelines Apply in Quebec
Federal Child Support Guidelines apply to Quebec divorces only when one parent resides outside the province but within Canada. Under the Divorce Act, R.S.C. 1985, c. 3, s. 15.1, federal guidelines govern inter-provincial support matters. Quebec courts processing divorces where one parent has relocated to Ontario, for example, would apply federal tables rather than Quebec's Basic Parental Contribution Table.
Frequently Asked Questions
How much is child support in Quebec for one child?
Child support in Quebec for one child depends on both parents' combined disposable income and parenting time arrangements. For a combined disposable income of $80,000, the Basic Parental Contribution Table specifies approximately $7,200 annually ($600 monthly) as the total contribution, divided proportionally between parents based on their income share and parenting time under Regulation C-25.01, r. 0.4.
Does Quebec use the federal child support guidelines?
No, Quebec does not use federal child support guidelines for intra-provincial cases. Quebec operates its own income-shares model under the Regulation respecting the determination of child support payments (C-25.01, r. 0.4), where both parents' incomes factor into the calculation. Federal guidelines only apply to approximately 5% of Quebec cases where one parent resides outside the province.
What is the basic deduction for Quebec child support in 2026?
The basic deduction for Quebec child support in 2025 is $13,575 per parent, indexed annually on January 1 based on the Quebec Pension Plan annual pension index. With the 2026 indexation factor of 3.2%, the 2026 basic deduction is approximately $14,009. This amount is subtracted from each parent's gross income before calculating disposable income.
How does shared parenting time affect child support in Quebec?
Shared parenting time (40-60% with each parent) significantly reduces child support payments in Quebec. Under Division 3 of the Regulation, both parents calculate their hypothetical payment as if they were the sole paying parent, and the higher earner pays only the difference to the other parent. With equal incomes and 50/50 parenting time, the net child support payment may be zero.
Is child support taxable in Quebec?
No, child support is not taxable income for recipients and not deductible for payers under any order or agreement made after April 30, 1997. This tax-neutral treatment applies under Income Tax Act § 56.1(3). Spousal support, however, remains taxable to recipients and deductible for payers.
At what age does child support end in Quebec?
Child support in Quebec has no fixed end age. Support continues as long as the child cannot meet their own needs, which typically includes adult children in full-time post-secondary education at CEGEP or university. Under Civil Code art. 585-586, parents must provide for dependent children regardless of age until they achieve financial independence.
How do I modify child support in Quebec?
To modify child support in Quebec, you can use SARPA (Child Support Recalculation Service) for simple income-based changes for just $57.25, or file a court application for complex modifications involving parenting time changes or disputed income calculations. Even agreed modifications require court homologation to be legally enforceable under Civil Code art. 594.
How does Revenu Quebec collect child support?
Revenu Quebec automatically collects child support for 87% of Quebec orders through the Support Payment Collection Program. Collection methods include automatic employer wage deductions (70% of cases), bank account levies, tax refund interception, and GST/HST credit seizure. Recipients receive payments twice monthly on the 1st and 16th via direct deposit or cheque.
What additional expenses can be added to child support in Quebec?
Beyond basic child support, Quebec courts add child care expenses (daycare, before/after school care), post-secondary education expenses (tuition, books, housing), and special expenses (medical treatments, orthodontics, private school, tutoring, extracurricular activities). These expenses are divided proportionally between parents based on their income shares under the Regulation.
Can I calculate Quebec child support online?
Yes, the Quebec government provides an official Child Support Payments Calculation Tool at quebec.ca designed to help you estimate the amount you should pay or receive for your children. This calculator applies the current Basic Parental Contribution Table and accounts for parenting time arrangements, though complex cases may require professional consultation.
