Quebec Child Support Calculator (Quebec Model, 2026 Table)

How the Quebec Model Works

Unlike the federal table amount, which is set from the paying parent's income, the Quebec model uses both parents' income and each parent's actual custody time. The calculation follows Parts 3 through 6 of the official form:

• Part 3: each parent's gross annual income, minus a basic deduction set annually by regulation ($13,865.00 for 2026) and any union or professional dues, gives each parent's disposable income and their income-share factor.
• Part 4: the combined disposable income and the number of children give, from the Schedule I table (C-25.01, r. 12), the basic parental contribution. Net child care, post-secondary, and special expenses (already reduced by any related credit, subsidy, or deduction) are added separately.
• Part 5: depending on custody time, one specific section of the form (1, 1.1, 2, 3, or 4) splits the basic contribution and expenses between the two parents.
• Part 6: support can never exceed 50% of the paying parent's disposable income (art. 8), unless the court decides otherwise.

Custody Types

Custody time is counted in days per year (up to 365), including time the child spends with a third party, such as daycare or school, while in that parent's care (art. 9(4)).

• Sole custody (Section 1): the other parent has 20% of the time or less (73 days or less).
• Extended access (Section 1.1): the other parent has over 20% to under 40% of the time (74 to 145 days), which produces a partial compensation.
• Sole custody split between the parents (Section 2): each parent has sole custody of at least one different child.
• Shared custody (Section 3): each parent has at least 40% of the time (146 days or more) for every child.
• Mixed custody (Section 4, art. 7): a combination of the above depending on the child. This calculator asks for custody time by group of children rather than a single blended percentage, specifically so it can detect these mixed situations instead of wrongly averaging them.

Worked Example

Two parents have two children. The father has a gross income of $55,155.00 and the mother $47,155.00. Net child care expenses total $2,000.00 a year, and the mother has sole custody.

• The 2026 basic deduction ($13,865.00) leaves disposable income of $41,290.00 (father) and $33,290.00 (mother), or $74,580.00 combined.
• The 2026 table gives a basic parental contribution of $14,530.00 for that combined income and two children, split by each parent's income share.
• Adding the net child care expenses ($2,000.00), the two parents' combined annual contribution (line 511) is $16,530.00.
• The father, the non-custodial parent, pays his share by his income-share factor: the result is $9,151.56 a year ($762.63 a month).

This uses the 2026 table (basic deduction $13,865.00), compared with the 2018 basic deduction of $11,155 in the official brochure this same income profile is drawn from. The calculator above runs the same calculation for any income, number of children, and custody arrangement.

The 2026 Table and Basic Deduction

The Schedule I table (annex to Regulation C-25.01, r. 12) is updated every year by ministerial order and published in the Gazette officielle du Québec; the version in force since January 1, 2026 (A.M. 5500) sets the basic deduction at $13,865.00. Unlike the annual indexation of existing orders (below), the table is not indexed by a fixed percentage; it is adjusted mainly for changes to the federal and provincial tax systems, so amounts can rise, fall, or stay flat from year to year. Above a combined disposable income of $200,000, the percentage applied to the excess is for information only (art. 10), and the court may fix a different amount for that portion. For more than 6 children, the amount is calculated from the difference between the 5- and 6-child amounts (r. 12, art. 1).

Indexation of Existing Orders

This calculator sets a new support amount. That is a different mechanism from the annual indexation of orders already fixed by judgment, under article 590 of the Civil Code of Québec: every January 1, an existing order is automatically adjusted by the annual pension index under the Quebec Pension Plan, unless the judgment or agreement says otherwise. For 2026, the Quebec government announced a 2% indexation, effective January 1, 2026. If you already have a court order, that 2% applies to your existing amount; it does not change the Schedule I table this calculator uses for a new case.

What This Tool Does Not Do

This calculator files nothing with a court and does not replace the official form or the Quebec government's own calculator (in French). The court keeps discretion: it can fix a different amount considering a parent's assets, the child's own resources, unusually high access costs, reasonable family debts, or support owed to children from another relationship. For a child of full age, the court can also depart from the model. Parents can agree to a different amount (Part 7 of the form, art. 587.3 C.C.Q.), subject to the court's review. Spousal support, if any, is fixed after child support. The Quebec model applies when both parents live in Quebec. If one parent lives outside Quebec, it still applies to requests filed in Quebec between common-law spouses, or on a legal separation, dissolution of a civil union, or annulment; for a divorce, the federal Guidelines (federal tables) apply instead, unless the parents agree to use the Quebec model. See the Quebec child support model for details.

This calculator uses the 2026 Quebec-model table (Regulation C-25.01, r. 12, Schedule I, A.M. 5500) and the Regulation respecting the Determination of Child Support Payments (C-25.01, r. 0.4).
