The federal benefits — the Canada Child Benefit and the GST credit — are paid in Quebec as everywhere, on federal family net income. Quebec adds its own, worked out on family income: line 275 of the Quebec returns of both spouses.
Paid through the year
- Family allowance (Retraite Québec), for each child under 18: $3,068 a child and $1,077 more for a single-parent family, less 4% of family income over $60,398 for a couple or $44,032 for a single parent — but never less than $1,221 a child and $430 for the single parent. Unlike the Canada Child Benefit, it does not fall to nil at high incomes.[1] Each July it adds $127 for every child aged 4 to 16 on the following 30 September, for school supplies.[2]
- Solidarity tax credit (Revenu Québec), for July to June: $363 for the individual, as much for a spouse, $172 more for a person living alone, and a housing amount of $906 for a couple or $746 for a person alone, plus $158 a child. The total is reduced by 6% of family income over $43,195.[3] The housing amount needs a home the household owns or rents, which every plan has.[4]
The planner pays both as a twelfth each month. Retraite Québec pays the allowance quarterly unless asked for monthly payments, and Revenu Québec pays a small solidarity credit quarterly or once a year; the year's total is the same.[5]
Paid with the Quebec return
- Work premium, for people who work but earn little: 11.6% of work income above $2,400 ($3,600 for a couple, counting both), up to the reduction threshold of $12,808 ($19,828 for a couple), then less 10% of family income above it. With a child at home the rate is 30% for a single parent and 25% for a couple. A couple gets it once.[6]
- Senior assistance credit: $2,000 for each spouse aged 70 or over, less 5.47% of family income over $28,405 for a person alone or $46,200 for a couple.[7]
Both are refundable: they come off the Quebec tax and are paid out when there is no tax to take them from. See income tax in Quebec.
What the planner does
The engine works these out for a Quebec household; the planner does not yet ask the questions the family benefits need (children, who receives them), the same as for Ontario's. Like the federal and Ontario benefits, they use the published 2026 figures in every year.
What it does not do
The supplements for children with disabilities, the allowance under shared custody, the adapted work premium and its advance payments, the solidarity credit's northern-village amount and a home shared with other adults are not modelled, nor are Quebec's refundable credits for childcare, medical expenses, caregivers, home support for seniors and working past 65.
