For the step by step on claiming Disability Tax Credit, please see:
How do I claim the disability tax credit?
Note: To qualify for the disability tax credit, you must have a certified Form T2201 (DTC application) on file with the CRA or the CRA will reject your claim.
Further information on Disability Tax Credit Certificate:
To apply, either the person with the disability or a legal representative must fill out Part A of Form T2201.
A medical practitioner is required to fill out Part B of the form. Depending on the type of impairment, a medical doctor, optometrist, audiologist, occupational therapist, psychologist, or speech-language pathologist may complete this portion.
When the form is completed, mail it to your nearest tax center.
After the Canada Revenue Agency receives Form T2201 – Disability Tax Credit Certificate, it will assess the validity of your claim.
If you are approved, the CRA will send a notice identifying the years for which you may claim the DTC. At the end of the identified time period, you will be required to resubmit an application if you want to continue to claim the DTC.
