What is Form T2201?
Form T2201 is the Disability Tax Credit Certificate, the application form for the credit. You complete the first part with your own information. A medical practitioner completes the rest, certifying how your impairment affects the basic activities of daily life and how long those effects have lasted. The CRA then decides whether you qualify.
Every Disability Tax Credit story passes through one document: Form T2201. It is not a long form, but it is a consequential one, and small choices on it, especially the choice to describe daily life honestly and in detail, shape the CRA’s decision. This walkthrough takes the form part by part so nothing on it surprises you.
Your part of the form
The opening part belongs to you or to the person completing the form on the applicant’s behalf. It covers identity and contact information, and it asks whether you want the CRA to adjust your tax returns for previous years if the application is approved. That adjustment question matters more than it looks. DTC approval can reach back up to 10 years when the effects were present, and asking for the adjustment on the form means those past years get revisited without a separate request.
Take care with the basics here. Names, dates, and the Social Insurance Number should match tax records exactly. Administrative mismatches slow files down for reasons that have nothing to do with the merits of the claim.
The practitioner’s part: where decisions are really made
The medical practitioner’s sections are the heart of the form. For each relevant category, walking, speaking, hearing, seeing, dressing, feeding, eliminating, or mental functions, the practitioner describes the effects of the impairment: what the person cannot do, what takes much longer, and how often help is needed. They also record when the effects began, which is what allows the CRA to approve past years.
Notice what the form does not ask for. It does not ask the practitioner to argue, persuade, or rate your worthiness. It asks for functional facts. The strongest forms I see are almost boring in their specificity: distances, minutes, frequencies, and examples. Thin forms share one trait: they name a diagnosis and stop, as though the label explained a life. It does not, and the CRA cannot approve what it cannot see.
Who can sign which sections
A medical doctor can certify every category. Other practitioners certify within their fields: optometrists for vision, audiologists for hearing, occupational therapists for walking, dressing, and feeding, physiotherapists for walking, speech language pathologists for speaking, and psychologists for mental functions, among others. The practical advice is to have the practitioner who knows the effects best complete the relevant sections, because familiarity shows in the quality of the description.
If your situation spans categories, say a mobility restriction alongside a mental functions restriction, the form has room for that, and the CRA also considers the cumulative effect of significant restrictions together. Do not trim your reality to fit one box if your life honestly occupies two. My overview of how to apply for the DTC places this form inside the full process.
After the form goes in
Submit the completed form to the CRA and keep a copy of everything, including the practitioner’s pages. The CRA may approve for a set period or indefinitely, may ask questions first, or may deny. Each outcome has a next step. Approvals connect to tax adjustments and to the RDSP. Requests for information are chances to add detail. Denials can be reviewed, and I wrote the guide on DTC denials for exactly that moment.
One practical note: practitioners may charge a fee for completing the form, and that fee can be claimed as a medical expense in many cases. Ask about the fee when you book the appointment so it is not a surprise at the desk.
Common questions
Can I fill in the T2201 myself?
You complete the first part with your information. The certification sections must be completed by a medical practitioner who can speak to the effects of your impairment. You cannot certify your own form.
What if my practitioner does not know the form?
Bring the form and a short written summary of how your impairment affects daily life: examples, times, and tasks you cannot do or that take much longer. Practitioners certify more accurately when the daily detail is in front of them.
Does the T2201 expire?
The form is submitted once per application. Approvals can be granted indefinitely or for a set period. If an approval period ends, a new form is needed to renew, which is why keeping your copy matters.
What happens if the CRA denies my T2201 application?
You can ask the CRA to review the decision with additional information, and you can file a formal objection. Many legitimate claims succeed on a second look when the daily life evidence is clearer.
