Top 5 Credits Canadians Miss by Not Filing Taxes
Even with zero income, you could be leaving thousands on the table. Here is what to claim.
Every year, an estimated $1.7 billion in benefits goes unclaimed because Canadians simply don't file their tax returns. Many believe that if they didn't earn an income, they don't need to file. This is the most expensive mistake you can make.
1. The GST/HST Credit
A tax-free quarterly payment that helps individuals and families with low and modest incomes offset all or part of the GST or HST they pay.
- Potential Value: Up to $496/year for singles.
2. Canada Child Benefit (CCB)
If you have children under 18, you are likely eligible for the CCB. However, the CRA cannot calculate your entitlement unless they have a record of your previous year's income.
- Potential Value: Thousands of dollars per child.
3. Canada Carbon Rebate (formerly CAIP)
Most residents of provinces like Ontario, Alberta, and Manitoba are eligible for this quarterly payment to offset the cost of federal carbon pricing.
- Requirement: You MUST file a T1 return to receive it.
4. Provincial Credits (e.g., OTB in Ontario)
Many provinces have their own "wrapped" credits for housing and energy.
5. RRSP Room Accrual
Even if you don't use it today, filing your taxes "records" your earned income, which generates RRSP contribution room you can use in future high-earning years.
