Quebec requires most child support payments to flow through Revenu Quebec's Support Payment Collection Program, with automatic wage deductions occurring on the 1st and 16th of each month. Under the Act to facilitate the payment of support (R.S.Q. c. P-2.2), Revenu Quebec acts as the mandatory intermediary between paying and receiving parents, collecting funds through source deductions from employment income and distributing payments twice monthly via direct deposit or cheque. This comprehensive 2026 guide explains every payment method available to Quebec parents, from automatic payroll deductions to direct payments with security deposits, helping you understand how to pay child support in Quebec efficiently and compliantly.

How Revenu Quebec Manages Child Support Payments
Revenu Quebec automatically collects child support from paying parents and distributes funds to receiving parents twice monthly on the 1st and 16th of each month. When a Quebec court issues a child support order or approves a parental agreement, the court clerk sends the judgment directly to Revenu Quebec, which opens a collection file and contacts both parents within 10 business days. The paying parent receives notice of the collection amount, payment schedule, and deduction method, while the receiving parent receives confirmation of expected payment dates and registration instructions for direct deposit.
Under Article 585 of the Civil Code of Quebec, both parents owe a legal obligation of support to their children regardless of marital status. This obligation alimentaire applies equally to children born within marriage, civil union, or common-law relationships. The Quebec Superior Court has jurisdiction over all child support matters under divorce proceedings governed by the Divorce Act, R.S.C. 1985, c. 3 (2nd Supp.), with Article 15.3(1) establishing child support as the top priority in any family law proceeding.
Primary Payment Method: Automatic Deduction at Source
Automatic deduction at source represents the default and most common payment method for Quebec child support, with Revenu Quebec deducting funds directly from the paying parent's employment income before the parent receives their paycheck. This wage withholding child support system ensures consistent, timely payments while eliminating the burden of manual payment processing. Revenu Quebec sends a deduction order to the paying parent's employer, specifying the exact amount to withhold from each pay period and the deadline for remitting funds to Revenu Quebec.
Employers receiving a support payment deduction order must comply within 10 days of receipt, deducting the specified amount from the employee's wages and remitting it to Revenu Quebec before the 16th of the following month. The employer cannot refuse to implement deductions or charge the employee administrative fees for processing support payments. If the paying parent changes employers, Revenu Quebec automatically sends a new deduction order to the new employer upon notification of the employment change.
Income Sources Subject to Automatic Deduction
Revenu Quebec can order deductions from multiple income sources beyond regular employment wages, including:
- Salary and wages from employment (most common)
- Commission income and bonuses
- Employment Insurance benefits
- Quebec Pension Plan (QPP) retirement benefits
- Registered Retirement Savings Plan (RRSP) withdrawals
- Rental income from investment properties
- Self-employment income (via quarterly payment orders)
- Workers' compensation benefits
- Private pension payments
When automatic deductions from one income source prove insufficient to cover the full child support amount, Revenu Quebec issues supplementary payment orders requiring the paying parent to remit the balance directly on the 1st and 16th of each month.
Payment Orders: The Self-Employed Alternative
Self-employed parents and those without regular employment income pay child support through payment orders issued by Revenu Quebec, requiring direct payments on the 1st and 16th of each month. Payment orders specify the exact amount due, payment deadline, and acceptable payment methods. Parents receiving payment orders must remit funds proactively rather than having amounts deducted automatically, making timely payment the parent's direct responsibility.
Under the payment order system, Quebec parents can remit child support through several methods:
- Online banking bill payment to Revenu Quebec
- Pre-authorized debit from a bank account
- Credit card payment through Revenu Quebec's secure portal
- Cheque or money order mailed to Revenu Quebec
- In-person payment at a financial institution
Payment orders also apply when source deductions cannot cover the full support amount, such as when the paying parent works multiple part-time jobs or receives income from multiple sources. Revenu Quebec calculates any shortfall between deducted amounts and ordered support, issuing payment orders for the difference.
Receiving Payments: Direct Deposit Setup
Quebec parents receiving child support should register for direct deposit to ensure funds arrive in their bank account on the 1st and 16th of each month without mail delays or lost cheques. Direct deposit registration through Revenu Quebec's state disbursement unit takes 2-4 weeks to process, with the receiving parent's first direct deposit occurring on the next scheduled payment date after registration completion.
How to Register for Direct Deposit
Three registration methods exist for setting up child support direct deposit with Revenu Quebec:
-
Online Registration via My Account: Log into Revenu Quebec's My Account portal at revenuquebec.ca, navigate to the support payments section, and enter banking information including institution number, transit number, and account number.
-
Form PPZ-109-V Submission: Download and complete form PPZ-109-V (Request for Direct Deposit of Support Payments) from Revenu Quebec's website, attach a void cheque or pre-authorized debit form, and mail to the address specified on the form.
-
Financial Institution Registration: Some Quebec banks and credit unions offer direct enrollment for Revenu Quebec direct deposit through their online banking portals.
When changing bank accounts, parents should wait until receiving at least one payment in the new account before closing the old account to prevent payment disruptions. Revenu Quebec requires 15 business days to process banking changes, and payments in transit during the transition period may still arrive at the former account.
Exemption from the Collection Program: Direct Payments Between Parents
Quebec parents who mutually agree to handle child support payments directly between themselves, without Revenu Quebec's involvement, may apply for an exemption from the Support Payment Collection Program. This exemption allows the paying parent to send payments directly to the receiving parent through e-transfer, cheque, or cash, but requires court approval and a mandatory security deposit equal to one month's child support amount.
Requirements for Exemption Approval
The exemption process requires:
-
Joint Agreement: Both parents must consent to direct payments in writing, submitted to the court during divorce or support proceedings.
-
Court Approval: A Quebec Superior Court judge must approve the exemption request, considering the best interests of the child and payment reliability concerns.
-
Security Deposit: The paying parent must provide security equal to one month's child support within 30 days of the judgment. Security may be cash (deposited with Revenu Quebec, earning interest at the prescribed rate), a suretyship, or a letter of guarantee from a financial institution.
-
Continuous Compliance: The paying parent must maintain timely payments. A single missed payment allows the receiving parent to request immediate cancellation of the exemption by submitting form PPA-104-V (Application for Cessation of Exemption).
Consequences of Exemption Cancellation
If the paying parent misses even one direct payment, the receiving parent can file form PPA-104-V with Revenu Quebec by registered mail, immediately reinstating the collection program. Revenu Quebec then seizes the security deposit to cover arrears and resumes automatic deductions or payment orders. The paying parent loses all exemption privileges and cannot re-apply for exemption for a minimum of 12 months.
Modifying Child Support Through SARPA
The Service administratif de rajustement des pensions alimentaires pour enfants (SARPA) allows Quebec parents to modify child support payments without returning to court when income changes warrant an adjustment. SARPA charges CAD $57.25 per application (indexed annually), with the service provided free to parents financially eligible for legal aid. Parents can submit SARPA applications online through the Commission des services juridiques portal.
SARPA Eligibility Requirements
SARPA modification applies when:
- The child receiving support is under 18 years old
- Both parents reside primarily in Quebec
- A final or temporary court judgment established the current support amount
- One or both parents experienced a significant income change
- Parents agree to recalculation or one parent requests review
SARPA cannot modify support when parents dispute parenting time arrangements, when the child has special needs requiring extraordinary expenses beyond basic support, or when one parent lives outside Quebec. These situations require a court application to the Quebec Superior Court.
SARPA Application Process
- Complete the online SARPA application at the Commission des services juridiques website
- Provide current income documentation (Notice of Assessment, pay stubs, self-employment records)
- Submit the CAD $57.25 application fee (waived for legal aid eligible parents)
- SARPA reviews both parents' financial situations and recalculates support using the Quebec Model
- Both parents receive the proposed new support amount for approval
- Upon approval, SARPA sends the modification to the court clerk for judicial confirmation
- The court clerk notifies Revenu Quebec, which adjusts collection amounts automatically
SARPA modifications typically process within 6-8 weeks from application submission to implementation of new payment amounts.
Quebec Child Support Calculation: Understanding Payment Amounts
Quebec uses a unique provincial calculation model under the Regulation respecting the determination of child support payments (C-25.01, r. 0.4) that considers both parents' incomes rather than only the paying parent's income like the Federal Child Support Guidelines used in other provinces. The Quebec Model calculates each parent's disposable income by subtracting a basic annual deduction (CAD $13,575 in 2025, indexed annually) from gross income, then uses the Basic Parental Contribution Table to determine total support based on combined disposable income and number of children.
Quebec Model vs. Federal Guidelines
| Factor | Quebec Model | Federal Guidelines |
|---|---|---|
| Income Considered | Both parents' incomes | Paying parent only |
| Basic Deduction | CAD $13,575 (2025) | None |
| Parenting Time Factor | Yes, detailed calculation | Limited adjustment |
| Special Expenses | Shared proportionally | Case-by-case |
| Calculation Tables | Basic Parental Contribution | Federal Tables |
For example, two Quebec parents with combined disposable income of CAD $167,000 and two children owe a total basic parental contribution of CAD $19,440 annually (CAD $1,620 monthly) according to the Basic Parental Contribution Table. This amount divides proportionally between parents based on their respective shares of combined income and the parenting time arrangement.
Enforcement When Payments Are Late
Revenu Quebec possesses extensive enforcement powers under the Act to facilitate the payment of support (R.S.Q. c. P-2.2) to collect overdue child support payments, including seizure of income, garnishment of bank accounts, interception of tax refunds, and reporting to credit bureaus. When a paying parent falls behind on support, Revenu Quebec automatically implements escalating enforcement measures without requiring the receiving parent to take legal action.
Enforcement Escalation Timeline
| Days Overdue | Enforcement Action |
|---|---|
| 1-10 days | Late payment notice issued |
| 11-30 days | Interest accrues at prescribed quarterly rate |
| 31-60 days | Security deposit seized (if applicable) |
| 61-90 days | Tax refund interception initiated |
| 90+ days | Bank account garnishment, credit bureau reporting |
Interest on late child support payments accrues at the rate prescribed by Revenu Quebec, which changes quarterly. The rate calculation rounds to the nearest whole number and increases by 3%. Parents can check current rates on Revenu Quebec's Interest Rates on Debts webpage.
Additional Enforcement Tools
For persistent non-payment, Revenu Quebec can:
- Register a legal hypothec against the paying parent's real property
- Suspend provincial licenses (driver's license, professional licenses)
- Seize lottery winnings and other provincial benefits
- Report arrears to federal programs, triggering passport denial
- Initiate contempt of court proceedings for willful non-payment
Inter-Provincial and International Support Collection
When the paying parent resides outside Quebec, the receiving parent can use the Reciprocal Enforcement of Support Orders (RESO) program to collect support across provincial and international borders. Under the Divorce Act section 18.1, either former spouse may commence proceedings to vary support when residing in different provinces, with the provincial child support service facilitating enforcement.
Quebec has reciprocal enforcement agreements with all Canadian provinces and territories, plus over 60 foreign countries including the United States. The receiving parent files an Application to Vary, Rescind or Suspend a Support Order with Quebec's Ministry of Justice, which transmits the request to the paying parent's jurisdiction for enforcement according to local procedures.
Tax Treatment of Quebec Child Support Payments
Child support payments in Quebec receive neutral tax treatment, meaning the paying parent cannot deduct child support from taxable income, and the receiving parent does not report child support as taxable income. This differs from spousal support, which remains tax-deductible for the payer and taxable for the recipient under both federal and Quebec provincial income tax rules.
Parents completing Quebec income tax returns should:
- Line 142: Receiving parents report support payments received (for tracking purposes only, not taxable)
- Line 225: Paying parents may deduct spousal support only (child support is not deductible)
Revenu Quebec issues annual statements to both parents confirming total support amounts paid and received during the tax year, which should reconcile with personal records before filing.
H2 Frequently Asked Questions About Quebec Child Support Payments
How do I pay child support in Quebec if I am self-employed?
Self-employed Quebec parents pay child support through payment orders issued by Revenu Quebec, requiring direct payments on the 1st and 16th of each month via online banking, pre-authorized debit, or cheque. Unlike employed parents who have automatic wage deductions, self-employed parents must proactively remit the full support amount before each deadline. Revenu Quebec may also require quarterly income reporting to verify payment accuracy based on actual self-employment earnings.
Can I pay child support directly to my ex-spouse in Quebec without going through Revenu Quebec?
Yes, but only with court approval and a security deposit equal to one month's child support. Both parents must jointly request an exemption from the Support Payment Collection Program during court proceedings, and the paying parent must deposit security within 30 days of the judgment. Missing even one direct payment allows the receiving parent to immediately reinstate Revenu Quebec's collection program by filing form PPA-104-V.
How do I set up direct deposit for receiving child support payments in Quebec?
Register for direct deposit through Revenu Quebec's My Account portal online, submit form PPZ-109-V by mail with a void cheque, or use your financial institution's Revenu Quebec enrollment feature. Processing takes 2-4 weeks, with payments depositing directly to your account on the 1st and 16th of each month. When changing banks, maintain your old account until confirming receipt of at least one payment in the new account.
What happens if the paying parent misses a child support payment in Quebec?
Revenu Quebec automatically enforces collection without requiring the receiving parent to take action. Within 30 days of non-payment, interest accrues at the quarterly prescribed rate. After 60 days, Revenu Quebec seizes any security deposit. After 90 days, bank account garnishment and tax refund interception begin, with credit bureau reporting following for persistent arrears.
How much does it cost to modify child support in Quebec?
SARPA modification costs CAD $57.25 per application (indexed annually), with the service free for parents eligible for legal aid. SARPA allows income-based modifications without court appearances when both parents reside in Quebec and the child is under 18. Court modifications for complex cases (disputed parenting time, special needs) require filing fees of CAD $108-$325 plus potential attorney costs of CAD $150-$500 per hour.
Does Quebec child support end when my child turns 18?
No, Quebec child support does not automatically end at age 18. Under Article 585 C.c.Q., the obligation alimentaire continues for adult children who cannot support themselves due to full-time post-secondary education, disability, or other circumstances. However, support for adult children covers only subsistence needs rather than the full Basic Parental Contribution Table amounts. Either parent may request SARPA modification or court variation when the child reaches majority.
Can grandparents be required to pay child support in Quebec?
Yes, under Article 585 of the Civil Code of Quebec, grandparents can be required to pay child support if the parents cannot fulfill their support obligation. The obligation alimentaire extends to relatives in the direct line, meaning grandparents may be ordered to contribute to grandchildren's support when parents lack sufficient income. This reciprocal obligation also allows elderly grandparents to claim support from adult grandchildren who have the financial means to contribute.
How does shared parenting time affect child support calculations in Quebec?
Quebec's Model accounts for parenting time by adjusting each parent's share of the basic parental contribution based on the percentage of time the child spends with each parent. In equal (50/50) parenting arrangements, the parent with higher income pays the difference between each parent's proportional contribution to the lower-income parent. The calculation uses the detailed form found in Schedule I of the Regulation respecting the determination of child support payments.
What if my ex-spouse moves out of Quebec owing child support?
Quebec participates in the Reciprocal Enforcement of Support Orders (RESO) program with all Canadian provinces and over 60 foreign countries including the United States. Contact Revenu Quebec to file an enforcement request, which transmits to the paying parent's new jurisdiction. The receiving jurisdiction's authorities garnish wages, seize assets, and intercept tax refunds according to their local enforcement procedures while crediting payments back to Quebec.
How long does Revenu Quebec keep my security deposit if I have an exemption?
Revenu Quebec holds the security deposit until the support obligation ends or you request return after meeting specific conditions. The deposit can only be returned after maintaining the exemption for at least 2 years, having zero arrears or fees owing, and obtaining the receiving parent's written agreement. If the support obligation ends through court-approved agreement, the deposit returns after Revenu Quebec receives the termination judgment.
