The Disability Tax Credit (DTC) is one of the most valuable tax credits available to Canadians with disabilities and their caregivers. It reduces federal taxes by approximately $1,500 per year and opens the door to other benefits including the Registered Disability Savings Plan. Despite its value, many eligible Canadians never apply. Here is who qualifies and exactly how to get it.
You may qualify for the DTC if you have a severe and prolonged impairment in mental or physical function. The CRA uses specific criteria to determine eligibility:
You are markedly restricted if you are unable to perform, or take an inordinate amount of time to perform, one of the basic activities of daily living, even with the use of appropriate devices and medications. Basic activities include:
Even if you are not markedly restricted in a single category, you may qualify if you have significant restrictions in two or more categories that together have effects equivalent to being markedly restricted in a single category. This provision helps people with multiple moderate impairments who might otherwise not qualify.
People who require life-sustaining therapy (such as kidney dialysis or insulin-dependent diabetes requiring multiple daily injections and blood glucose testing) may also qualify even if they are not markedly restricted in the basic activities.
The DTC is based on functional impact, not diagnosis. Common conditions that may meet the criteria include:
The key is whether the condition is severe and prolonged (lasting 12 months or more or expected to recur regularly) and whether it markedly restricts daily functioning.
Applying for the DTC requires completing form T2201 (Disability Tax Credit Certificate). The process involves two parts:
You complete this section with your personal information and describe the impairment and its effects on your daily activities.
A qualified medical practitioner must complete and certify Part B. Depending on the type of impairment, different practitioners can certify: physicians, optometrists (for vision), audiologists (for hearing), occupational therapists (for mobility, feeding, and dressing), psychologists (for mental functions), and others as listed by the CRA.
Submit the completed T2201 to the CRA. Processing takes several weeks. Once approved, the DTC typically covers multiple years — the CRA specifies the period for which you are certified.
Once approved by the CRA, you claim the DTC on Schedule 1 of your return (line 31600). If you are approved but had no taxes to pay in previous years, you can request retroactive adjustments for up to 10 years — this can result in a significant lump-sum payment.
If the person with a disability has insufficient income to use the full DTC, the unused portion can be transferred to a supporting person such as a parent, spouse, grandparent, sibling, or other qualifying relative. The supporting person claims it on line 31800 of their return. This makes the DTC valuable even for children or low-income adults.
Children under 18 who qualify for the DTC receive an additional supplement worth over $900 in 2024. This is particularly important for parents of children with significant disabilities.
DTC approval makes you eligible for the Registered Disability Savings Plan, which provides significant government matching grants and bonds. The Canada Disability Savings Grant matches contributions up to 300%. People with low family income receive the Canada Disability Savings Bond with no required contribution. The RDSP is one of Canada's most powerful savings programs for people with long-term disabilities.
If the CRA denies your DTC application, you have the right to object. Many initial denials are reversed on appeal, especially when the application is accompanied by more detailed medical documentation. Consider working with a disability tax specialist who can help prepare a stronger application.
