Canada Workers Benefit (CWB) Factors for for Quebec

Income Tax Act s. 122.7

The Canada Workers Benefit (formerly the working income tax benefit, or WITB) is a refundable tax credit. The following table summarizes the CWB amounts for Quebec. In this table the word couple refers to a person with an eligible spouse. See the CWB article for eligibility requirements.

The amounts for all other provinces and territories are provided in the other CWB table.

As part of the 2021 budget, a "secondary earner exemption" was introduced, which is a special rule for individuals with an eligible spouse. This allows the lower-income spouse to exclude up to $14,000 (indexed after 2021) of their working income in the computation of the couple's adjusted net income, for the calculation of the CWB phase-out. This change was also adopted by Quebec.

Note that in the table, couple refers to a couple where both are eligible for the CWB.

All amounts/factors which change annually based on indexation adjustments appear in green print and are shaded, and have been increased based on the Quebec indexation factor. The 2023 amounts have been confirmed to Canada Revenue Agency amounts.

All amounts/factors which are revised by the Quebec reconfiguration agreement are shaded gray. The amounts in green print which are not shaded are calculated amounts, based on the rates as well as the other amounts in green print.

The Detailed Quebec Tax & RRSP Savings Calculator includes the CWB factors as shown below.
