What is the Disability Tax Credit (DTC) in Canada and who qualifies?

The Disability Tax Credit (DTC) is a non-refundable tax credit designed to reduce the federal and provincial/territorial income tax payable by individuals with a severe and prolonged impairment, or by the person supporting them.

Eligibility Criteria:

To qualify for the DTC, an individual must have a medical practitioner certify on Form T2201, Disability Tax Credit Certificate, that they have a severe and prolonged impairment that meets specific criteria defined under the Income Tax Act. The impairment must be one of the following:

• Marked Limitation: The individual is markedly restricted in the performance of a basic activity of daily living (e.g., seeing, speaking, hearing, walking, or feeding oneself) even with appropriate aids or the use of medication.
• Life-Sustaining Therapy: The individual requires therapy to support a vital bodily function (e.g., insulin therapy for diabetes, or dialysis).
• Time Requirement: The impairment must have lasted, or be expected to last, for a continuous period of at least 12 months.

Impact on Tax Filing:

If the DTC is approved by the CRA, the individual can claim the base amount plus any applicable supplement amounts (for children or individuals over 65) on their tax return. Since it is a non-refundable credit, it can reduce tax payable to zero, but it will not generate a refund on its own. However, eligibility for the DTC often opens the door to claiming other related benefits, such as the Canada Caregiver Credit (CCC) or contributions to a Registered Disability Savings Plan (RDSP).

Who Claims the Credit:

• If the individual is 18 or older, they claim the credit themselves.
• If the individual is under 18, the parent or supporting person claims the credit, provided they meet the dependency tests.

Application Process:

The application requires certification by a licensed medical practitioner. Once certified, the approval is usually valid for a set period, requiring periodic renewal. If the impairment is expected to last for life, the CRA may grant approval indefinitely.

It is important to note that the DTC is separate from, but often complements, the deduction for medical expenses. Medical expenses are deducted from income, whereas the DTC is a direct reduction against tax payable.
