Apply for the Disability Tax Credit
Loading article…
Applying for the Disability Tax Credit (DTC) in Canada can reduce your tax burden and unlock access to other federal benefits. If you or someone you support has a severe and prolonged impairment, understanding how to apply for disability tax credit is the first step toward claiming this valuable non-refundable credit from the Canada Revenue Agency (CRA).
Get your DTC application approved by following this complete guide to eligibility, Form T2201, and the CRA review process.
What Is the Disability Tax Credit?
The Disability Tax Credit is a federal non-refundable tax credit designed to reduce the income tax owed by Canadians with severe and prolonged impairments. It also serves as a gateway to additional benefits and savings programs.
Unlike a refund cheque, the DTC lowers your taxable income. If you have little or no tax payable, the credit can be transferred to a supporting family member who does.
For 2026, the federal disability amount is $10,341, plus a supplement of up to $6,032 for persons under 18. Rates and terms may vary by financial institution and provincial programs.
Approval for the DTC also unlocks access to the RDSP, a long-term savings vehicle with government grants and bonds, and the new Canada Disability Benefit for low-income applicants.
Who Qualifies for the DTC?
To qualify, you must have a severe and prolonged impairment in physical or mental functions. The CRA defines “severe” as a marked restriction in at least one basic activity of daily living, or significant limitations in two or more categories.
“Prolonged” means the impairment has lasted, or is expected to last, for a continuous period of at least 12 months. The condition must be present all or substantially all the time.
- Walking: Unable to walk 100 metres or takes at least three times longer than an average person
- Speaking: Unable to speak so as to be understood in quiet settings, even with therapy or devices
- Hearing: Unable to hear even with a hearing aid
- Mental functions: Marked restriction in memory, problem-solving, goal-setting, or judgment
- Feeding or dressing: Unable to perform these tasks independently or takes at least three times longer
- Life-sustaining therapy: Requires therapy at least three times per week, averaging 14 hours total (expected to drop to two times per week in 2026)
You do not need to be completely unable to perform an activity. The CRA assesses whether your impairment significantly restricts your ability compared to others your age.
How to Apply: Step-by-Step
Applying for the Disability Tax Credit requires completing Form T2201, the Disability Tax Credit Certificate. The form has two parts: one you complete, and one your medical practitioner certifies.
Step 1: Complete Part A
Part A is the applicant section. You (or your legal representative) provide personal details: name, address, Social Insurance Number, and date of birth. This section also asks who will claim the credit.
You can complete Part A online through My CRA Account or download the PDF version from the CRA website. If applying online, you will receive a reference number to share with your medical practitioner.
Take your time. Double-check that all information matches your CRA records exactly. Errors in this section can delay processing.
Step 2: Medical Certification
Part B must be completed and signed by a qualified medical practitioner. Depending on your condition, this may be a doctor, nurse practitioner, psychologist, occupational therapist, audiologist, or speech-language pathologist.
Your practitioner must describe how your impairment affects your daily functioning in clinical, functional terms. The CRA does not approve based on diagnosis alone—they evaluate the impact on activities of daily living.
- Be specific: Track examples for at least six weeks before your appointment—document time, supervision, and frequency
- Use functional language: Instead of “struggles with routines,” state “requires 45 extra minutes and continuous prompting to complete morning self-care”
- Bring evidence: Provide your practitioner with detailed notes, therapy reports, or school assessments that support your application
- Complete only relevant sections: Your practitioner should fill out only the categories that apply—leave others blank
Many applications are denied because the medical section lacks sufficient detail, not because the applicant is ineligible. Clear, concrete descriptions significantly improve approval rates.
Medical practitioners may charge a fee for completing Part B. In many cases, this fee can be claimed as a medical expense on your tax return.
Step 3: Submit Your Application
Once both parts are complete and signed, submit Form T2201 to the CRA. You have two options: upload it through My CRA Account using the “Submit documents” feature, or mail the signed original to your tax centre.
Your medical practitioner can also submit Part B online directly if you provide them with your reference number from Part A.
Keep copies of everything. If the CRA requests additional information later, you will need to reference what was submitted.
After You Apply
Processing Times
The CRA typically takes three to six months to review a DTC application. Processing times can vary depending on the complexity of the case and whether additional medical information is required.
You can check the status of your application through My CRA Account. The progress tracker shows where your application is in the review process.
Possible Outcomes
After reviewing your application, the CRA will send a Notice of Determination. There are three possible outcomes:
- Approved: The notice will state the years you are eligible for. The CRA may reassess your previous tax returns automatically and issue refunds if applicable
- Denied: The notice will explain why the application was not approved, usually due to insufficient functional detail in Part B
- Request for more information: The CRA may send a questionnaire to your medical practitioner asking for clarification or additional evidence
If approved, the credit can be applied retroactively for up to 10 years and claimed annually going forward, as long as your approval remains valid.
If Your Application Is Denied
A denial does not mean you are ineligible. Most denials result from incomplete or unclear medical descriptions, not from a lack of qualifying conditions.
You have three options if your application is denied:
- Reapply with updated information: Work with your medical practitioner to provide more detailed functional descriptions and resubmit Form T2201
- Request an informal review: Contact the CRA to discuss the decision and provide additional medical documentation
- File a formal objection: Submit a Notice of Objection within 90 days of the denial date using Form T400A, online through My CRA Account, or by mail
When filing an objection, provide new or more detailed medical information that clearly demonstrates how your impairment meets the CRA’s severity and duration criteria.
Claiming the Credit
Once approved, the Disability Tax Credit must still be claimed on an income tax return. Because it is a non-refundable credit, its value depends on whether you or a supporting person had income tax payable during the approved years.
If you have enough taxable income, you claim the credit on your own return. If your income is too low to use the full credit, you can transfer the unused portion to a spouse, common-law partner, or supporting family member.
The CRA may automatically reassess your previous tax returns for approved years. If you paid income tax in those years, this may result in a refund.
Approval also makes you eligible for the Registered Disability Savings Plan, a long-term savings tool with government matching grants and bonds. Consider exploring tax-advantaged savings options to maximize your financial planning.
Bottom Line
Applying for the Disability Tax Credit requires careful attention to Form T2201, particularly the medical certification in Part B. The CRA evaluates functional impact, not diagnosis, so detailed descriptions of time, supervision, and severity are critical.
Many Canadians who qualify delay applying because the process feels overwhelming. In reality, the biggest obstacle is ensuring your medical practitioner uses the right language to describe how your impairment restricts daily activities.
If approved, the DTC can deliver retroactive refunds for up to 10 years and unlock access to the RDSP, Canada Disability Benefit, and provincial supports. Stay informed about other financial tools by signing up for our newsletter to receive expert guidance delivered to your inbox.
