The Disability Tax Credit (DTC) is a federal tax benefit that helps Canadians living with serious medical conditions reduce the amount of income tax they owe.
If you or a loved one are dealing with a disability, the DTC can provide significant financial relief — including access to retroactive refunds and other government programs.
But qualifying isn’t always straightforward.
Below, we explain who qualifies, how the process works, and what to do if your application is denied.
What Is the Disability Tax Credit?
The Disability Tax Credit is a non-refundable tax credit offered by the Canada Revenue Agency (CRA).
It’s designed to:
- Offset the extra costs of living with a disability
- Reduce the amount of income tax payable
- Help unlock access to other benefits (like the RDSP)
Who Qualifies for the Disability Tax Credit?
To qualify for the DTC, you must have a severe and prolonged impairment in physical or mental functions.
This includes conditions that:
- Are expected to last at least 12 months
- Significantly restrict your ability to perform basic daily activities
- Require life-sustaining therapy
Common qualifying categories:
- Vision (e.g. blindness)
- Walking and mobility
- Mental functions (e.g. memory, problem-solving)
- Dressing or feeding yourself
- Speaking or hearing
- Life-sustaining therapy (e.g. dialysis)
What Medical Conditions Qualify?
There’s no fixed list — the CRA focuses on how your condition affects your daily life, not just the diagnosis.
However, many approved claims involve:
- Chronic pain and fibromyalgia
- Depression, anxiety, and other mental health conditions
- Neurological disorders (e.g. MS, Parkinson’s)
- Severe ADHD or learning disabilities
- Diabetes requiring intensive therapy
- Mobility impairments
How Much Is the Disability Tax Credit Worth?
The DTC can reduce your taxes by thousands of dollars per year.
You may also be eligible for:
- Retroactive payments (up to 10 years)
- Transfers to a spouse or caregiver
- Additional provincial tax credits
How to Apply for the Disability Tax Credit
Applying for the DTC involves submitting a T2201 Disability Tax Credit Certificate to the CRA.
The process:
- Complete Part A (basic information)
- Have a qualified medical practitioner complete Part B
- Submit the form to the CRA
- Wait for approval (can take several weeks or longer)
Why Are DTC Applications Denied?
Many valid claims are denied — often due to how the application is completed, not because the person doesn’t qualify.
Common reasons include:
- Insufficient detail from the medical practitioner
- Focusing on diagnosis instead of functional limitations
- Missing information about daily restrictions
- CRA not clearly understanding the severity of the condition
What Happens If Your DTC Is Denied?
A denial is not the end of the process.
You may be able to:
- Request a review or reconsideration
- Submit additional medical information
- File a formal objection if necessary
The key is to address the gaps in the original application.
Can You Claim the DTC Retroactively?
Yes.
If approved, you can request adjustments for prior years — typically up to 10 years back.
This can result in substantial lump-sum refunds, especially for long-term conditions.
Key Takeaways

Frequently Asked Questions
How long does it take to get approved for the DTC?
It can take several weeks to a few months, depending on CRA processing times and the completeness of your application.
Can mental health conditions qualify for the DTC?
Yes. Conditions like depression, anxiety, and cognitive impairments may qualify if they significantly restrict daily functioning.
Do I need a diagnosis to qualify?
A diagnosis helps, but approval depends on functional limitations, not just the condition itself.
