How to Fill Out CRA Form T2201 for Disability Tax Credit

CRA Form T2201, the Disability Tax Credit Certificate, has two parts: Part A is completed by you (or your legal representative) with basic identifying information, and Part B is completed by an authorized medical practitioner who describes how your severe and prolonged impairment restricts your daily functioning. Learning how to fill out CRA Form T2201 well is mostly about two things: making sure the right practitioner signs the right section, and making sure Part B describes your restrictions in concrete, measurable terms rather than in vague language. The CRA bases its decision almost entirely on what the practitioner writes, not on the diagnosis itself.¹

Before You Start: Confirm You Meet the Criteria

The form is a poor tool if the underlying eligibility isn’t there. The core requirement is a severe and prolonged impairment in physical or mental functions.² Prolonged means the impairment has lasted, or is reasonably expected to last, at least 12 continuous months.³

You also need a marked restriction in at least one basic activity of daily living. A restriction is “marked” when, all or substantially all of the time, you are either unable to perform the activity or it takes roughly three times longer than someone of the same age without an impairment, even with therapy, medication, and assistive devices. The recognized categories are vision, speaking, hearing, walking, eliminating (bowel or bladder), feeding, dressing, and mental functions needed for everyday life.⁴

Two other paths exist. If no single limitation is marked on its own, you can qualify through the cumulative effect of two or more significant limitations that exist together at least 90 percent of the time and combine to the equivalent of a single marked restriction.⁵ Or you can qualify through life-sustaining therapy that you receive at least twice per week, averaging at least 14 hours weekly, counting time for administering medication, adjusting dosages, maintaining therapy equipment, managing required dietary restrictions, and keeping a therapy log. Time spent exercising, travelling to appointments, or recuperating does not count.⁶

Pick the Right Practitioner for Your Impairment

Not every health professional can certify every section. Get this wrong and the CRA will reject the certification, no matter how thorough the write-up is. Medical doctors and nurse practitioners can certify any section of the T2201. The other practitioners are limited:

Optometrist: vision
Audiologist: hearing
Speech-language pathologist: speaking
Psychologist: mental functions
Occupational therapist: walking, feeding, and dressing
Physiotherapist: walking

Before booking, confirm your practitioner is authorized for the specific category you’ll be claiming under.⁷ You can download the current version of the form from the CRA website or request a paper copy by phone.⁸

Part A: What You Fill Out

Part A is short but every field is mandatory. Leaving one blank can cause the CRA to return the form without reviewing it. Fill in your name, mailing address, date of birth, and Social Insurance Number.

If a spouse, parent, or other supporting family member will be claiming the credit on your behalf because you don’t owe enough tax to use it yourself, add their information in Part A now. Doing so at this stage makes the transfer straightforward at tax time. If you skip it, that family member will later have to send the CRA a signed written request explaining the support they provide.⁹

Part A also contains a checkbox asking the CRA to automatically adjust your prior tax returns if you’re approved. Check it. If you skip it, you’ll have to submit a separate T1 Adjustment Request for each retroactive year, which is significantly more work.⁷

Part B: What Your Practitioner Fills Out

This is where applications succeed or fail. Your practitioner answers questions about the nature, severity, and duration of your impairment. A diagnosis alone does not qualify you. Diabetes, MS, autism, and every other named condition all have to be described in terms of functional restriction: what you can’t do, or how much longer it takes you than it would take someone your age without the impairment.¹

Come to the appointment prepared with specific examples. If dressing takes 45 minutes instead of 10, say so. If someone has to cut your food at every meal, say so. If you get lost on familiar streets or can’t follow a two-step instruction, describe an incident. Phrases like “has difficulty” are where most applications fall apart, because they don’t tell the CRA whether the restriction meets the threshold. The practitioner needs enough detail to describe the restriction concretely.

If you’re applying under the cumulative-effect path, make sure the practitioner addresses each of the significant limitations and how they overlap in time. If you’re applying under life-sustaining therapy, the practitioner needs to document the frequency, weekly hours, and what those hours are spent on.

The practitioner signs and dates Part B. Review it before you submit. If a section is thin or uses vague language, ask whether it can be expanded. It is far easier to strengthen the description now than to argue it back on objection later.

How to Submit the Completed Form

Once both parts are complete and signed, you have two options. Submit electronically through the “Submit documents” feature in CRA My Account or My Business Account, which gives you immediate confirmation of receipt.⁷ Or mail a paper copy to the Sudbury Tax Centre or the Winnipeg Tax Centre.¹⁰

After You Submit: Timeline and Decision

The CRA’s standard processing target is roughly eight weeks, though the agency has acknowledged delays beyond that.¹¹ An assessor checks the medical information in Part B against the requirements in the Income Tax Act and may contact your practitioner directly for clarification or additional records.

You’ll receive a notice of determination by mail or through your online account telling you whether you were approved, which tax years are covered, and whether your eligibility has an expiry date or is indefinite. Keep the notice. Approval is also the gateway to the Registered Disability Savings Plan and, for approved children under 18, the Child Disability Benefit, so the letter has uses beyond your tax return.¹²

If You’re Denied

The denial letter will explain why. Read it carefully before deciding what to do next. In many cases the issue is how Part B was completed rather than whether you genuinely qualify. If the practitioner’s descriptions were vague or didn’t address the specific thresholds, resubmitting with a more detailed Part B often resolves the problem faster than a formal challenge.

You also have the right to file a formal income tax objection within 90 days of the date on the notice of determination.¹³ That window is firm. If the objection is unsuccessful, the next step is an appeal to the Tax Court of Canada.
