Canada Workers Benefit (CWB) Factors for 2021 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 Federal 2021 Budget provided enhancements to the CWB amounts. The amounts for all other provinces and territories are provided in the other 2021 CWB table. The amounts for Quebec depend on a provincial reconfiguration agreement, which has now been finalized. See the Quebec 2021 Reconfigured CWB Parameters pdf file.

As part of the 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 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. All amounts/factors which were revised by the Quebec reconfiguration agreement are shaded gray. The amounts in green print which are not shaded change 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, and has been updated with the revised CWB amounts/factors for 2021.
