Frequently Asked Questions
What is CRA Form T2201 and how do I apply for the Disability Tax Credit?
CRA Form T2201 (Disability Tax Credit Certificate) consists of Part A (completed by you or your representative) and Part B (completed and certified by your medical doctor, nurse practitioner, or specialized health professional). You can submit it online via CRA My Account or by mail.
How do I renew my Disability Tax Credit (DTC) certificate before it expires?
The CRA will mail you a notification letter one year prior to your DTC expiration date. To renew, you must submit a new Form T2201 certified by your medical practitioner, or submit a renewal through your CRA My Account portal. If your condition is deemed permanent/indeterminate, CRA may grant an indefinite approval with no renewal required.
Which medical practitioners are authorized to certify Form T2201?
Medical doctors and nurse practitioners can certify all impairment categories. Specialists can certify specific sections: psychologists (mental functions), optometrists (vision), audiologists (hearing), occupational therapists (walking, feeding, dressing), physiotherapists (walking), and speech-language pathologists (speaking).
What qualifies under the cumulative effects of significant restrictions?
If you do not have a single impairment that is markedly restricted 90% of the time on its own, you may qualify under cumulative effects if you have two or more significant restrictions (e.g., walking and speaking, or dressing and mental functions) that together equal a marked restriction.
Can I claim the DTC if I have no taxable income?
Yes. If the person with the impairment does not have sufficient taxable income to utilize the non-refundable credit, the unused credit amount can be transferred to a supporting spouse, parent, child, or family member who provided regular support (food, shelter, clothing).
How far back can retroactive DTC refunds be claimed from the CRA?
Under section 152(4.2) of the Income Tax Act, the CRA allows retroactive tax adjustments and direct refunds up to 10 calendar years preceding the year of approval using CRA Form T1-ADJ or automatic CRA adjustment requests.
