What Is Disability Tax Credit in Canada?
Disability is far more common in Canada than you may think. In fact, 27% of Canadians aged 15 and older – nearly 8 million people – lived with a disability in 2022, according to Statistics Canada’s 2022 Canadian Survey on Disability. That was up from 22%, or 6.2 million people, in 2017.
When you or someone you care for is living with a physical or mental impairment, managing the financial side of that situation can add another layer of stress. The good news is that there are Canadian tax support available to help you. Beyond provincial programs and benefits, you may also qualify for the federal Disability Tax Credit (DTC), which can reduce the amount of income tax you owe.
Before applying, you need to know what the Disability Tax Credit is. Depending on your CRA-approved eligibility period, you may also be able to claim the disability amount for previous tax years, potentially going back up to 10 years.
For Azim Dahya, CPA at Advanced Tax Services, understanding the DTC is about looking beyond the credit itself.
The Disability Tax Credit is more than a line on your tax return. Understanding your eligibility, the years you qualify for, and how the credit fits with other available tax benefits will help you make informed decisions about your overall tax situation.
In this guide, we’ll explain what the Disability Tax Credit is, who may qualify, the criteria for Disability Tax Credit, and how to apply for the Disability Tax Credit for yourself or a family member.
What Is Disability Tax Credit and How Does It Work?
The Disability Tax Credit (DTC) is a non-refundable federal tax credit designed to help people with physical or mental impairments, as well as eligible supporting family members, and reduce the income tax they may have to pay. It is also a federal income tax credit and, depending on the year, can reduce federal income tax by about $1,500.
For 2026, the Government of Canada set the federal disability amount at $10,341, providing a federal tax reduction of up to $1,448.
The key phrase here is non-refundable. The DTC can reduce the amount of income tax you owe, but if the credit is greater than the tax you owe, the remaining amount is not paid to you as a refund.
The process has two main parts. First, you apply to the Canada Revenue Agency (CRA) to determine whether you are eligible. If your application is approved, you can then claim the disability amount on your income tax return.
DTC eligibility may also open the door to other government programs for you, including the Registered Disability Savings Plan (RDSP), Canada Workers Benefit (CWB) disability supplement, Child Disability Benefit (CCB), and Canada Disability Benefit
List of Disabilities That Qualify for Disability Tax Credit Canada
If you are looking for a list of disabilities that qualify for Disability Tax Credit Canada, there is something important to know: the CRA does not approve the DTC simply because someone has been diagnosed with a particular medical condition.
Instead, the CRA looks at how severe and prolonged impairment affects activities of daily living and physical functions, not just the diagnosis.
The DTC covers several categories of physical and mental functions, including:
- Walking
- Mental functions necessary for everyday life
- Dressing
- Feeding
- Eliminating – including bowel or bladder functions
- Hearing
- Speaking
- Vision
- Life-Sustaining Therapy
This distinction is important, because disability can affect people in different ways. Statistics Canada reported that pain-related disabilities were the most common disability type in 2022, affecting 62% of Canadians with disabilities. Mental health-related, seeing, learning, memory, and developmental disabilities also increased a lot between 2017 and 2022.
For example, having difficulty walking does not automatically mean you qualify for the DTC. The CRA looks at the severity, frequency, and duration of the restriction. The same principle applies to mental functions, dressing, feeding, hearing, and other eligible categories.
This means two people with the same medical condition could receive different eligibility decisions because their impairments affect their daily lives differently.
Another common misunderstanding is that being unable to work automatically qualifies someone for the DTC. It does not. DTC eligibility is based on whether the effects of an impairment meet the CRA’s specific criteria—not simply whether someone has a diagnosis or is able to work.
Criteria for Disability Tax Credit
The eligibility criteria for Disability Tax Credit can vary depending on the type of impairment, but one of the most important concepts to understand is whether the person has a severe and prolonged impairment in physical or mental functions and a marked restriction.
Generally, a marked restriction means you are unable to perform an eligible activity or it takes you at least three times longer than someone of a similar age without the impairment, even with appropriate therapy, medication, and devices, and the assessment looks at how you function even when using appropriate devices.
The restriction must generally also:
- be present all or almost all the time, which the CRA generally interprets as 90% or more; and
- have lasted or expected to last for a continuous period of at least 12 months.
There is also a life sustaining therapy category with its own rules, and qualifying life-sustaining therapy must generally be medically required at least three times per week.
What If You Have More Than One Limitation?
Not everyone fits neatly into one category.
You may have significant limitations in two or more areas that do not individually meet the marked restriction criteria. In some situations, the CRA can consider their cumulative effect.
For example, someone who consistently takes a long time to both walk and dress may have limitations that, when considered together, are equivalent to a marked restriction in one activity.
Having multiple limitations does not automatically mean you qualify. The CRA will make its decision based on whether the combined effects meet its criteria and the information provided by your medical practitioner.
How to Apply for the Disability Tax Credit
If you think you or a family member may qualify, knowing how to apply for the Disability Tax Credit can make the process feel much more manageable. To claim it, you must be a resident of Canada for tax purposes.
The DTC application involves both the applicant and an appropriate medical practitioner. You do not need to be a Canadian citizen or permanent resident if you are a resident of Canada for tax purposes and have the required identifying information.
Step 1: Complete Your Part of the Application
You can apply digitally or use DTC Form T2201, Disability Tax Credit Certificate. For a paper application, the person with the impairment—or their legal representative—completes Part A. You will need to provide basic information such as your name, mailing address, date of birth, and Social Insurance Number, and this section should be completed accurately before the form is sent for medical certification as a completed form.
Information about a supporting family member may also be required if the disability amount could be transferred. In that case, details about an eligible family member, including a spouse or common law partner in some cases, may be relevant.
Step 2: Have a Medical Practitioner Complete Their Part
A qualified medical practitioner must complete Part B, describe and certify the effects of the impairment, and provide detailed functional descriptions of how it affects daily activities, as CRA requires that level of detail for approval.
Depending on the type of impairment, this may be a:
- Medical doctor
- Impairments Nurse Practitioner
- Optometrist
- Audiologist
- Occupational therapist
- Physiotherapist
- Psychologist
- Speech-language pathologist
Incomplete Part B sections and missing details are common reasons a disability tax credit application is denied.
Your medical practitioner provides the medical information, but they do not make the final DTC decision. The CRA determines whether you are eligible. Any fees for completing the form may qualify as a medical expense, depending on the situation.
Step 3: Submit Your DTC Application
You can apply using the CRA’s digital application process to submit documents or mail the current paper version of Form T2201.
If you are applying by paper, make sure you are using the latest form. If mailing it, send it to the appropriate tax centre and keep a copy of the completed form. The CRA announced that beginning September 8, 2026, versions of Form T2201 from before 2023 will no longer be accepted.
Step 4: Wait for the CRA’s Decision
Once the CRA has reviewed your application, it will send you a notice of determination explaining whether you have been approved and the years for which you are eligible. CRA review typically takes 3 to 6 months, though timelines can vary.
You can also follow the status of your disability tax credit application through the progress tracker in your CRA account while it is under review after the CRA receives the completed application.
What Happens After Your DTC Application Is Approved?
Getting approved is important, but there may still be a few tax decisions to make. Your notice of determination tells you which years you are eligible for the DTC. You can then determine how to claim the disability amount on your tax return and whether there are previous returns that should be reviewed.
For 2026, the federal disability amount is $10,341. Eligible minors may also qualify for an additional supplement of $6,032, subject to reductions such as attendant care expenses where applicable.
If you were eligible for the DTC in previous years but did not claim the disability amount, the CRA says you may be able to claim it going back up to 10 years. Depending on your circumstances and previous tax returns, a past-year credit could result in a tax refund.
If you do not need the full disability amount to reduce your income tax, some of the unused amounts may be transferred to a supporting family member, subject to the maximum disability amount. DTC approval may also increase the Child Disability Benefit and can affect access to other government programs.
You do not necessarily need to reapply every year. Your approval period depends on your circumstances, and the CRA will indicate when your eligibility expires or whether you have been approved on an ongoing basis.
Common Questions About the Disability Tax Credit
DTC eligibility depends on meeting the eligibility criteria for a severe and prolonged impairment in physical or mental functions, rather than on diagnosis alone. Depending on the eligibility category, the CRA considers factors such as how severely the impairment restricts you, how frequently the restriction occurs, and how long it has lasted or is expected to last.
Some applicants may also qualify under the life-sustaining therapy category, including insulin therapy or oxygen therapy when they support a vital function and meet CRA rules.
A DTC application requires information from the person with the impairment or their legal representative, along with a section that is completed and signed by an appropriate medical practitioner before you submit the documents.
Detailed descriptions of how the impairment affects daily activities can help establish eligibility. The medical practitioner provides information about the effects of the impairment, and the CRA makes the final eligibility decision.
No. Among Canada tax credits, the DTC has its own eligibility and application requirements. You generally need to apply and receive CRA approval before claiming the disability amount on your tax return.
DTC eligibility may also help provide access to certain other federal benefits, government programs, and related tax credits.
There is no simple list of diagnoses that automatically qualify someone for the DTC. Instead, the CRA looks at the effects of a severe and prolonged impairment in specific categories such as walking, mental functions, dressing, feeding, eliminating, hearing, speaking, vision, and life-sustaining therapy, rather than at a diagnosis alone.
Potentially, yes. If you were eligible in previous years but did not claim the disability amount, the CRA says you may be able to claim it for up to 10 previous years, depending on your approved eligibility period.
