As of July 14, 2026, and again on September 8, 2026, changes are coming to the way Canadians with disabilities can apply for the Disability Tax Credit (DTC).
The changes are relatively minor and are unlikely to affect most applicants. However they do make it more important to use the correct application process and the most current versions of the forms.
In brief, applicants will no longer be able to apply by uploading a scanned copy of a paper form, and outdated versions of the paper form will no longer be accepted. Applicants can still apply online, by phone, or by mail.
What is the Disability Tax Credit?
The Disability Tax Credit (DTC) is a non-refundable tax credit for people with disabilities, or for people who support family members with disabilities. It reduces the amount of income tax an eligible person may have to pay. Unlike some government benefit programs, the Disability Tax Credit is not a cash payment.
The DTC is intended to help offset extra costs related to impairments by reducing the amount of income tax an eligible person has to pay.
Who is Eligible for the Disability Tax Credit?
People with Disabilities
To qualify, you must have one of the following:
- a severe and prolonged impairment, also called a marked restriction, in one category;
- significant limitations in two or more categories; or
- a need for therapy to support a vital function.
Supporting Family Members
If the person with the eligible disability is dependent on a supporting family member, the supporting family member may be able to claim the DTC if the person with the disability qualifies.
This helps offset the additional cost of taking care of a family member with an eligible disability.
Can the Disability Tax Credit be Shared?
Yes.
If the person with the eligible disability wants to share the credit with a supporting family member, or if the credit needs to be split between more than one supporting family member, this can be done.
However, the total amount claimed cannot be more than the maximum amount allowed for the person with the eligible disability.
What is a Marked Restriction?
A marked restriction, or a severe and prolonged impairment, means that you are unable to do an activity in one of the eligible categories, or that it takes you three times longer to do the activity than someone of the same age who does not have the impairment.
This applies even if you use therapy, medication, or assistive devices.
The restriction must be present all or almost all of the time, meaning 90% or more of the time. You must have the restriction, or expect to have it, for a continuous period of at least 12 months.
What Are The Eligible Categories?
To qualify, a person must experience a severe and prolonged impairment in one or a cumulative impairment in two or more of the following categories of functions of daily activity:
- walking;
- mental functions;
- dressing;
- feeding;
- eliminating, meaning bowel or bladder functions;
- hearing;
- speaking;
- vision; and
- life-sustaining therapy.
What Is The Cumulative Effect Rule?
If you have a significant limitation in two or more categories, you may still qualify for the DTC.
The combined limitations must exist all or almost all of the time, meaning 90% or more of the time.
If the limitations were combined, the combined impact must be equal to being unable to do, or taking three times longer to do, an activity in one of the categories. The combined impact must also be present all or almost all of the time, even with devices, medication, and therapy.
How Much Is the Disability Tax Credit Worth?
For the 2025 tax year, the disability amount is $10,138.
For a person under the age of 18, there is also an additional supplement for children of $5,914.
The disability amount may change every year.
Can You Claim Previous Years?
If you were eligible to claim the DTC in the past but did not claim the disability amount, you may be able to claim it going back up to 10 years.
You can do this by:
- checking the box on your application to claim previous years;
- writing to the CRA to ask them to adjust your returns; or
- adjusting your returns online yourself.
If you are eligible for a credit because of the adjustment, the CRA will issue the amount to you by cheque or direct deposit. This only happens with a retroactive adjustment.
What is Changing in 2026?
Honestly, not much.
You will still be able to apply online or by mail. The CRA will still contact you through your CRA account or by mail.
The biggest changes relate to how applications are submitted, rather than who qualifies for the Disability Tax Credit.
Key Dates to Remember
July 14, 2026

Are These Changes Good or Bad?
To give a stereotypical lawyer answer: it depends.
The possible benefits include:
- faster processing
- easier access to decisions
The possible drawbacks are:
- Accessibility concerns for people who do not have access to technology
- Some doctors may also prefer not to use the online platform.
