It’s possible to go back 10 years to file or modify a tax return. An amendment may allow you to correct an error in your file or include a forgotten deduction/credit. The production from a previous year can allow you to obtain certain refunds and/or credits:

  • Federal and provincial tax withheld at source too much

  • Working Income Tax Benefit (WITB)

  • The work premium, adapted work premium and the supplement to the work prenium (Quebec)

  • GST credit

  • Solidarity Tax Credit (Quebec)

  • Canada Child Tax Benefit (CCTB) | Canada Child Benefit (CAC)

  • Universal Child Care Benefit (UCCB)

  • Child Assistance (Quebec) 

  • Tuition Tax Credit


In some cases, non-production of your tax returns can trigger unfortunate consequences (fines, legal mortgage, wage seizure, etc.).


We can also recover some tax slips that you would have lost.
