Disability Tax Credit (DTC)

Offered by Canada Revenue Agency

Federal non-refundable tax credit for people with severe and prolonged impairments, or supporting family members, subject to medical certification and CRA approval.

Disability Tax Credit (DTC) in Canada: A Guide for Families of Autistic Children

If your child has autism and experiences significant challenges with daily living, you may be eligible for the Disability Tax Credit (DTC). The DTC is one of the most important federal disability programs in Canada because it can reduce income taxes and open the door to other financial supports, including the Registered Disability Savings Plan (RDSP).

What Is the Disability Tax Credit?

The Disability Tax Credit (DTC) is a non-refundable tax credit provided by the Canada Revenue Agency (CRA). It is designed to help offset some of the additional costs associated with living with a disability.

For children, the credit is typically transferred to a parent or caregiver who supports them financially.

Can Children with Autism Qualify?

Yes. A diagnosis of autism alone does not automatically qualify a child for the DTC, but many autistic children are eligible if their condition causes significant and prolonged difficulties in everyday functioning.

Eligibility is based on how the disability affects daily life, not solely on the diagnosis itself.

Examples of challenges that may support eligibility include:

How Do You Apply?

Step 1: Complete the digital DTC application or Form T2201

You can apply using the CRA's digital DTC application or the paper Form T2201 – Disability Tax Credit Certificate.

The form has two parts:

Depending on your child's situation, this may be:

Step 2: Submit the Application

Use the CRA's digital DTC application or mail the completed paper form. Do not upload a PDF or scan through the general “Submit documents” section of a CRA account; that route no longer accepts DTC applications. In the digital process, your medical practitioner submits Part B using the reference number you provide.

Step 3: Wait for CRA's Decision

The CRA reviews the application and determines eligibility.

Processing times vary and may range from several weeks to several months.

How Much Is the Tax Credit Worth?

The exact value changes each year because tax amounts are indexed.

For many families, DTC eligibility can result in:

The actual savings depend on family income and tax circumstances.

Can You Receive Retroactive Benefits?

Yes.

If CRA approves the DTC and determines your child was eligible in previous years, tax returns may be reassessed for up to 10 prior years.

Many families receive significant refunds through these reassessments.

The DTC Can Unlock Other Programs

One of the biggest benefits of DTC approval is access to additional programs.

Registered Disability Savings Plan (RDSP)

The DTC is generally required to open an RDSP.

An RDSP allows families to:

For many families, the RDSP is one of the most valuable financial planning tools available.

Canada Child Disability Benefit (CDB)

Families with DTC-approved children may also qualify for the Child Disability Benefit, a tax-free monthly payment that supplements the Canada Child Benefit.

Common Reasons Applications Are Denied

Some applications are denied because:

When completing the application, it is important to describe how autism affects your child's day-to-day functioning compared to other children of the same age.

Should You Use a DTC Consultant?

Some companies offer to help families apply for the DTC in exchange for a percentage of any refund received.

Many families successfully complete the application on their own with assistance from their healthcare provider.

Before signing any agreement, carefully review fees and understand what services are being provided.

Final Thoughts

The Disability Tax Credit can provide meaningful financial support for families raising autistic children in Canada. Beyond the tax savings, DTC approval can open access to valuable programs such as the RDSP and Child Disability Benefit.

If you believe your child may qualify, speak with your healthcare professional about completing Form T2201 and consider applying. Even if your child was diagnosed years ago, retroactive eligibility may result in substantial tax refunds and future financial benefits.

Eligibility

The CRA assesses whether the applicant has a severe and prolonged impairment under DTC rules. Autism diagnosis alone does not establish eligibility.

How to apply

Complete the applicant portion of the digital or paper DTC application, have an eligible medical practitioner certify the relevant impairment information, and submit through the CRA's current DTC process or by mail.
