Upgrading of Residential Waste Water Treatment Systems - Quebec line 462

You may qualify for this refundable tax credit for the upgrading of residential wastewater treatment systems for the years 2017 to 2022, but you must comply with the following conditions.

a) You were resident in Québec on December 31, 2021.

(b) You or your spouse have entered into an agreement after March 31, 2017 with a qualified contractor to perform the work on a qualifying home (i.e., as a rule, a home in Quebec owned by you that constitutes your place of residence or, under certain conditions, a year-round residential cottage that you own and normally occupy).


The amount of credit you can claim in 2021 for a qualifying home is 20% of the eligible expenses paid after March 31, 2017 that exceeds $2,500. The maximum tax credit is $5,500 per eligible home.

To claim this refundable credit, please follow these steps:

1. On the "Left-side menu of the Interview tab", select the "Quebec crédits".

2. On the right-hand side of the screen, scroll down to the "Quebec line 462" group and click the plus sign "+" icon to the right of the line for "TP-1029.AE- Tax credit for the upgrading of residential wastewater treatment systems".

3. In the page that appears, enter the required information. Note that the lines followed by a red asterisk (*) are mandatory.

4. In the "Information about the renovated dwelling" section answer the questions, if there is more than one owner, go to bottom of the section, right, and click the plus sign "+ Add Another" and enter the name of the co-owner.

5. For each of the other sections, such as "Information about the work done", enter the relevant information. If you want to add further information, follow the procedure outlined in step 4.

6. If you paid fees to obtain licences, including the cost of studies to obtain such licences, go to the "3.3 Licence costs" section and enter the information.

7. In the "Government or non-government assistance" section, the amount you enter will reduce the refundable tax credit.
