Disability Tax Credit and Its Impact on Accessing the Canada Disability Benefit
When the Canada Disability Benefit (CDB) launched in 2025, it was celebrated as a landmark program aimed at lifting people with disabilities out of poverty. But there’s an important detail many Canadians are only discovering now: to access the CDB, you first have to qualify for the Disability Tax Credit (DTC).
For many, this extra requirement can feel like a hidden hurdle—and it’s one that can block access to much-needed financial support.
What Is the Disability Tax Credit (DTC)?
The DTC is a non-refundable tax credit meant to reduce the income tax burden for people with disabilities and their caregivers. To qualify, an applicant must submit a form signed by a medical professional showing they have a severe and prolonged impairment in one or more areas of daily living.
Approval gives access not only to the tax credit itself, but also to related programs such as the Registered Disability Savings Plan (RDSP) and now, the Canada Disability Benefit (CDB).
Why the DTC Requirement Matters
By linking the new Canada Disability Benefit to DTC approval, the government effectively created an extra layer of eligibility screening.
Barrier to entry: If your DTC application is denied, you cannot receive the CDB—even if you clearly meet the CDB’s intended purpose.
Unfair exclusions: People with episodic disabilities (such as multiple sclerosis or certain mental health conditions) often find it harder to demonstrate eligibility under the DTC’s strict criteria.
Complex paperwork: Many Canadians struggle with the forms, medical documentation, and technical language required for a successful DTC application.
Advocacy groups have raised concerns that this gatekeeping may exclude many of the very people the CDB was designed to help.
Common Reasons DTC Applications Are Denied
Insufficient detail from doctors: Applications often fail because medical professionals don’t provide enough specifics about the impairment’s daily impact.
Focus on diagnosis instead of function: The DTC doesn’t assess your condition name—it looks at how it affects your ability to walk, feed, dress, or manage mental functions.
Episodic symptoms: If your condition is not constant, but still severely limiting, it can be harder to explain within the DTC framework.
How to Improve Your Chances of Approval
If you’re applying for the DTC to access the Canada Disability Benefit, here are some practical steps:
Work closely with your medical provider. Provide them with detailed examples of daily challenges so they can complete the form accurately.
Focus on function, not just diagnosis. Describe how impairments limit everyday activities, even if they fluctuate.
Include additional documentation. Attach supporting medical notes, test results, or specialist letters when possible.
Be prepared to appeal. If your first application is denied, you can request a reconsideration and, if needed, take the matter to the Tax Court of Canada.
Why Legal Support Can Help
Many people who genuinely qualify for disability supports are denied at the DTC stage simply because their application was incomplete or poorly framed. Since the Canada Disability Benefit depends on DTC approval, getting this step right is critical.
