What is the DTC?IN BRIEF
The Disability Tax Credit (DTC) helps eligible Canadians pay less tax, receive higher family allowances (for parents or guardians of a disabled child), access the Registered Disability Savings Plan (RDSP) and other helpful programs. Applying is free.

Who is the DTC for?
For all Canadians who meet one or more of the following criteria:
- Are disabled
- Are parents of disabled children
- Have a disabled dependent
What is considered a disability?
To qualify for the Disability Tax Credit (DTC), you or your dependent must have a significant and long-term impairment. An activity must be impossible to perform or take at least three times longer than someone of the same age without an impairment, even with care, tools, or medication. The limitation must be present almost all the time and has lasted or is expected to last at least 12 months.Types of activities taken into account for the DTC
- Walking
- Mental functions
- Dressing
- Feeding
- Eliminating (bowel or bladder functions)
- Hearing
- Speaking
- Vision
- Life-sustaining therapy
As well as the combination of two or more categories
When only one of the challenges does not meet the criteria, it is also possible to combine two of them. This does not include life-sustaining therapy.Autism and the DTC
Since 2021, the “Mental Functions” category allows many autistic people to qualify for the DTC, even if they function in the other categories. The same goes for people with a mental health disorder, disabling ADHD, Tourette syndrome, intellectual disability, and other similar conditions.

Preparation
It’s best to be prepared before going to the health care professional.
- Complete an initial version of the form yourself
- Ask family members for help so you don't forget anything
- Seek the advice of family and friends to ensure that all aspects are covered.
Many people don’t realize just how much is in place around them to help them function. Asking others for their opinion helps to get a more complete answer.
Then talk to your health-care professional to ensure that you include as much detail as possible on the form. A simple diagnosis is not enough to qualify for the tax credit.
For the doctor
Here’s some additional information for doctors about the expanded criteria.

It’s a good idea to gather all the information, reports, and follow-ups you already have, for the meeting with the healthcare professional responsible for completing Part B of the form. The more complete the information, the better the professional will be able to support the request.
Next steps
Once eligibility for the DTC has been confirmed, the Registered Disability Savings Plan (RDSP) can be opened for the disabled person or their dependent.
