The Disability Tax Credit (DTC) is a non-refundable federal income tax credit that reduces the amount of income tax owed by individuals with severe and prolonged impairments in physical or mental function. It is governed by sections 118.3 and 118.4 of the Income Tax Act, RSC 1985, c 1 (5th Supp).
Eligibility
To qualify, an individual must have a severe and prolonged impairment — meaning it has lasted or is expected to last at least 12 consecutive months — in one or more of the following functions: vision, speaking, hearing, walking, eliminating, feeding, dressing, or mental functions necessary for everyday life. A qualified practitioner (medical doctor, nurse practitioner, optometrist, audiologist, physiotherapist, occupational therapist, or psychologist, depending on the category) must certify the impairment on Form T2201.
When CRA Denies Your Application
The Canada Revenue Agency (CRA) reviews T2201 forms and may deny the credit if it determines the impairment does not meet the statutory threshold. Denials are common and are not necessarily final. Applicants have two avenues for challenging a denial:
1. Objection under Section 165
Within 90 days of the mailing date of the Notice of Assessment (or Notice of Determination), you may file a Notice of Objection with the CRA. The objection is reviewed by the Appeals Division, which is independent of the initial assessor. The objection should include a clear explanation of why eligibility criteria are met, supported by updated medical evidence and a revised or supplementary T2201 if appropriate. There is no fee to file an objection.
2. Appeal to the Tax Court of Canada
If the objection is unsuccessful or CRA does not respond within 90 days of filing the objection, the applicant may appeal to the Tax Court of Canada. Most DTC appeals proceed under the Informal Procedure, which is designed to be accessible to self-represented litigants and involves no filing fee for amounts under $25,000. Hearings are conducted before a Tax Court Judge. The Court is not bound by CRA’s interpretation and applies the statutory tests independently.
Common Reasons for Denial and How to Address Them
- Insufficient medical detail on the T2201 — Practitioners often complete the form too briefly. A supplementary letter with specific functional details (time taken, frequency of difficulty, need for assistance) significantly strengthens an application.
- Wrong practitioner type — Each category of impairment requires certification by a specific type of practitioner. Mental functions, for example, must be certified by a medical doctor or psychologist.
- Cumulative effects argument — Where no single impairment meets the threshold, cumulative effects of multiple impairments may still qualify under the mental functions category.
Retroactive Claims
If approved, the DTC can be claimed retroactively for up to 10 years under the Voluntary Disclosures Program or by filing amended returns, potentially resulting in significant refunds.
