Disability Tax Credit: prove effects, not diagnosis alone.
The DTC is not an autism grant. A medical practitioner describes the effects of impairment, and the Canada Revenue Agency decides whether the statutory criteria are met.
Review the CRA applicationDoes autism qualify for the Disability Tax Credit? Short answer.
Yes, if a medical practitioner certifies that autism’s effects meet the Canada Revenue Agency’s eligibility criteria on Form T2201. That means a marked restriction in daily functioning, present most or all of the time, expected to last at least 12 months. Autism alone is not the test. The CRA does not certify a diagnosis — it certifies documented functional effects. The practitioner applies by completing the medical section of Form T2201, and the CRA decides.

Does autism qualify for the Disability Tax Credit?
Autism does not automatically qualify a person for the Disability Tax Credit (DTC). Two autistic children with the same diagnosis can receive different DTC outcomes, because the form asks about daily functioning, not the diagnostic label itself. A practitioner who describes concrete examples — how long a task takes, how much support a routine requires, what happens without that support — gives the CRA the evidence the functional-effects test actually asks for. A form that repeats the diagnosis without those examples gives the CRA nothing to certify. That is why two otherwise similar applications can land on opposite outcomes. The diagnosis is a starting point. The medical section is where the case is made or lost.
| Question | What the page says | Source |
|---|---|---|
| What is certified? | The Canada Revenue Agency does not certify a diagnosis — it certifies the day-to-day functional effects of impairment. | Who is eligible for the disability tax credit |
| What is recorded? | A medical practitioner completes CRA Form T2201, describing how those effects meet the statutory duration and severity tests. | How to apply for the disability tax credit |
| Who decides? | The CRA then decides whether the application is approved. | Who is eligible for the disability tax credit |
Diagnosis alone does not decide the outcome. The medical section and its concrete daily examples do. Families sometimes assume an autism diagnosis is enough on its own, then find their application returned for more information. Ask the medical practitioner to describe effects, not only the condition.
How do I apply with Form T2201?
- Start by choosing a medical practitioner permitted to certify the relevant impairment.
- Give them full context about daily functioning, not just the diagnosis.
- The practitioner completes the medical section of Form T2201, describing how the effects meet the statutory duration and severity tests: a marked restriction that is present most or all of the time and expected to last at least 12 months.
- Review the completed form before it is submitted, and keep a copy.
- Once submitted, the CRA may approve the application, deny it, or request more information.
- Track the case through CRA’s own channels and respond by any stated deadline.
- A missed deadline can close the file.
- Approval or denial applies to the tax years the certified period covers.
- A denial can be appealed or resubmitted with a stronger medical section, if the underlying functional effects were not fully described the first time.
Can adults with autism get the DTC?
Yes. The DTC applies at any age. The credit includes a supplemental amount for applicants under 18, but adults with autism can also qualify when the same functional-effects test is met. An adult application is assessed the same way a child’s is — against documented daily functioning, not the diagnosis by itself. An adult who was never assessed as a child is not disqualified by the delay. The CRA looks at current functional effects and, where relevant, how long those effects have applied. Approval can also be claimed retroactively, for up to ten years of past tax returns. That matters most for adults who were eligible in earlier years but never applied.

What does the DTC give you access to?
An approved DTC gives you access to the Registered Disability Savings Plan (RDSP) and the Canada Disability Benefit. The RDSP is a long-term savings plan, not an immediate therapy fund. Its grants, bonds, withdrawals, and repayment rules depend on federal terms and individual circumstances, and DTC status must be confirmed before an RDSP can be opened. The DTC itself is a tax credit. Its dollar value on any single return depends on the claimant’s income and circumstances, so this guide does not estimate an individual result. Approval can be claimed retroactively, for up to ten years of past tax returns, so an approved application can also trigger a reassessment of prior years. This page does not give tax advice. The CRA decides eligibility, and a tax professional can confirm what an approval means for a specific return or reassessment. To see how DTC approval opens RDSP eligibility, read the DTC and RDSP guide.
