Yes, autism qualifies for Canada's Disability Tax Credit (DTC) under "mental functions necessary for everyday life." A psychologist or physician certifies Form T2201. Approval provides $1,400-$2,500/year federal tax relief and unlocks RDSP grants up to $90,000 lifetime. Retroactive claims up to 10 years are possible.

The Disability Tax Credit (DTC) is a federal non-refundable tax credit administered by the Canada Revenue Agency (CRA). It is designed to offset some of the costs faced by Canadians with severe and prolonged physical or mental impairments. "Non-refundable" means the credit reduces income tax owing — it does not result in a direct cash refund on its own.
The DTC applies to the federal portion of income taxes. If the individual with a disability does not have sufficient income to use the full credit, it can be transferred to a supporting parent, spouse, or common-law partner.
Beyond its direct tax benefit, the DTC is a key eligibility gateway for other programs, including the Registered Disability Savings Plan (RDSP) and the Canada Disability Benefit (CDB).
Disclaimer: Tax credit amounts and rules may change with federal budgets. Always verify current credit amounts on Canada.ca.
Yes — autism frequently qualifies for the DTC. The relevant eligibility category is "mental functions necessary for everyday life," which is covered in Section B of Form T2201. This category applies when a person has a severe and prolonged impairment in one or more mental functions, including:
The CRA does not approve based on diagnosis alone. What matters is the functional impact of the condition. A child who has an autism diagnosis but whose symptoms are mild and well-managed may not qualify; a child who requires significant support for daily functioning is more likely to meet the threshold.
The impairment must be "severe" — meaning it must take three times longer than typical to perform the relevant mental functions, or they cannot be performed at all — and it must be prolonged (lasting or expected to last at least 12 continuous months).
DTC denials are common and do not necessarily mean your child does not qualify. Many denials result from insufficient documentation on the T2201, not from the applicant being genuinely ineligible.
Steps to take after a denial:
Disability tax advocacy organizations and some non-profits can assist families through this process at no cost.
An approved DTC certificate opens doors to multiple other programs:
Yes, autism frequently qualifies for the Disability Tax Credit under the "mental functions necessary for everyday life" category. This covers significant limitations in adaptive functioning, memory, problem-solving, and judgment. The key is that a qualified medical practitioner — such as a registered psychologist or physician — must certify on Form T2201 that these limitations are present and have lasted (or are expected to last) at least 12 continuous months.
To apply, have your child's psychologist, paediatrician, or family physician complete Form T2201 (Disability Tax Credit Certificate). The form has two parts: Part A (completed by you, the applicant) and Part B (completed by the medical practitioner). Submit the completed form to the Canada Revenue Agency. Processing can take several months. If approved, the credit may be transferred to a supporting parent or guardian if the child cannot use it.
For the "mental functions" category (which covers autism), a medical doctor (MD) or a registered psychologist can certify Form T2201. The certifier must be licensed to practice in Canada. A psychologist is often the most appropriate certifier for autism, as they can speak directly to cognitive and adaptive functioning limitations. Other practitioners (occupational therapists, speech-language pathologists) can certify specific categories but not the mental functions category.
If the CRA denies your DTC application, you have the right to object. First, request a formal objection within 90 days of the decision notice. Gather additional supporting documentation from your psychologist or physician that more specifically describes functional limitations — not just the diagnosis. You can also request the CRA's Medical Review Services for a second look. If the objection fails, you can appeal to the Tax Court of Canada. Many initial denials are overturned on appeal with better documentation.
An approved DTC certificate is the key to several other federal benefits. It unlocks eligibility for the Registered Disability Savings Plan (RDSP), which comes with federal matching grants and bonds. It is also the primary gateway to the Canada Disability Benefit (CDB), a newer federal cash benefit for low-income adults with disabilities. The DTC itself reduces federal income tax owing — and if the person with a disability cannot use the credit, it can be transferred to a supporting family member.
