If you qualify for the Disability Tax Credit (DTC), you may be entitled to thousands of dollars in tax savings — including retroactive payments going back years.
Many Canadians are surprised to learn that even if they were recently approved, they could still receive a lump-sum refund for prior years.
Here’s how it works.
What Is a DTC Refund?
The Disability Tax Credit reduces the amount of income tax you owe.
If you were eligible in previous years but didn’t claim it, the Canada Revenue Agency (CRA) may allow you to:
- Adjust past tax returns
- Claim missed credits
- Receive a retroactive refund (up to 10 years)
How Far Back Can You Claim the DTC?
In most cases, you can claim the Disability Tax Credit retroactively for:
- Up to 10 previous years
The CRA will reassess your prior tax returns and calculate how much you should have received.
How Much Is the Disability Tax Credit Worth?
The amount varies depending on:
- Your income
- Your province
- The number of years you’re approved for
However, many people receive:
- Thousands of dollars per year in tax savings
- Significant lump-sum refunds for past years
Who Receives the Refund?
The refund may go to:
- You (if you pay income tax)
- A supporting family member (if the credit is transferred)
This is especially helpful if:
- You have low or no taxable income
- A spouse or caregiver supports you financially
What If You Were Just Approved?
If you’ve recently been approved for the DTC, the CRA may:
- Automatically reassess prior years
- Or request additional information before issuing refunds
In some cases, you may need to request adjustments manually.
