Is there a tax credit for upgrading of residential waste water treatment systems , I paid out 10,518.54 for Municipality sanitary sewage works connection fee

Hi there! 

You may be entitled to this tax credit if all of the following conditions are met:

• You were resident in Québec on December 31, 2022 (or on the day you ceased to reside in Canada in 2022).
• You or your spouse had work done to upgrade the residential waste water treatment system of an eligible dwelling under a contract entered into with a qualified contractor after March 31, 2017 (generally speaking, an eligible dwelling is a dwelling you own in Québec that is your principal residence or, subject to certain conditions, a cottage).
• The expenditures incurred for the work were paid in 2022.

This tax credit applies to 2017 through 2027. The maximum tax credit for the entire period is $5,500 per eligible dwelling.

Hope this helps
