Filling Out the T2201 Form for the Disability Tax Credit in 2026

Form T2201 is the Disability Tax Credit Certificate, the one form you need before the Canada Revenue Agency (CRA) will let you claim the Disability Tax Credit. Since September 8, 2026, the CRA only accepts the 2023 version or newer, so an outdated copy from a drawer will not be accepted.

The credit is worth about $1,448 in federal tax for 2026, plus a provincial amount, and an approval can reach back up to 10 years. That is real money for a lot of families, and the form is shorter than its reputation.

This guide walks through the two parts of the form, who is allowed to sign each one, the three ways to send it in, and what to expect after the CRA says yes.

What is the T2201 form for?

Form T2201 tells the CRA that a medical practitioner has certified a severe and prolonged impairment. Once the CRA approves it, you or a family member who supports you can claim the disability amount on a tax return. The approval can also cover earlier years, which is where most of the value sits for people applying later in life.

The form has two parts. Part A is yours. It asks who you are, who might claim the credit, and whether you want past returns adjusted. Part B belongs to your medical practitioner, who describes how the impairment affects your daily life. You can read the CRA's own description on its How to apply page (updated August 16, 2026).

One thing the form is not: a diagnosis form. The CRA decides on the effects of a condition, not its name. That matters for the conditions common after 65, which we cover below. For a deeper look at the eligibility rules themselves, our Disability Tax Credit eligibility guide for seniors is the companion to this post.

Which version of the T2201 form does the CRA accept now?

Since September 8, 2026, the CRA only accepts T2201 forms from the 2023 version or newer. An older form means starting again on the current one. The CRA announced the change in a June 16, 2026 tax tip. If you or your practitioner already filled in an older copy, it has to be redone on the current form or through the digital application.

You can spot the version in the file name. The current English file is named T2201-fill-23e. Anything from 2022 or earlier is out.

The safest route is to download the form fresh from the CRA's T2201 page the day you start, or skip paper and use the digital application described below. Do not use a PDF saved from a charity or clinic website in a previous year, even a helpful one. In September 2026 at least one high-ranking website was still offering the 2022 file.

Who can sign Part B, and what to have ready

Part B must be completed by a medical practitioner the CRA recognizes for that category. A family doctor or nurse practitioner can certify every category. Other regulated professionals can sign for the category they work in, which can save you weeks if the wait for your doctor is long.

Source: CRA, How to apply, updated August 16, 2026. Eliminating (bowel or bladder) and life-sustaining therapy need a doctor or nurse practitioner. The federal government proposed in May 2026 to add podiatrists to this list; as of the CRA's August update, that change was not yet in effect.

Before you book anything, have these four things ready:

1. Your Social Insurance Number (SIN) and current mailing address for Part A.
2. The name and SIN of the family member who may claim the transferred amount, if it will not be you.
3. The year the restriction began, as best you can date it. Your practitioner will confirm it, and it sets how far back the CRA can go.
4. A short written note of what takes you longer or what you cannot do, in plain terms. Practitioners fill Part B faster and better when you arrive with specifics.

How to apply for the disability tax credit: the three routes

The CRA offers three ways to get a complete T2201 to them. Since July 14, 2026 there are only two final delivery channels, the dedicated digital application or the mail, and both parts of the form must travel by the same route.

1. You start online. Sign in to CRA My Account, choose Benefits and credits, then Apply for DTC (the CRA's short form for the Disability Tax Credit). Complete Part A and you receive a reference number. Give that number to your practitioner, who enters it in the CRA's digital application for medical practitioners and submits Part B electronically. The reference number is valid for up to 12 months and can be used once. If you would rather not use My Account, you can complete Part A by phone with a CRA agent at 1-800-959-8281.
2. Fully on paper. Download the current form. You complete and sign Part A. Your practitioner completes and hand-signs Part B. Mail both parts together to your tax centre: Jonquière (2251 René-Lévesque Blvd, Jonquière QC G7S 5J2), Sudbury (PO Box 20000, Station A, Sudbury ON P3A 5C1) or Winnipeg (PO Box 14000, Station Main, Winnipeg MB R3C 3M2). The CRA's How to apply page tells you which centre serves your province.
3. Your practitioner starts online, you finish on paper. Some clinics fill Part B in the online tool, print it, sign it and hand it to you. That does not submit anything by itself. You then complete and sign Part A and mail the whole package.

Do not upload a new T2201 through the general "Submit documents" button in My Account. Since July 2026 the CRA only accepts it there if they have asked you for it.

Filling in Part A, section by section

Part A is four short sections. The notes below follow the paper form.

Section 1, person with the disability. Your name, address, date of birth and SIN.

Section 2, person intending to claim the disability amount. Fill this in if a spouse, common-law partner or adult child who supports you may claim some or all of the credit. Naming them here avoids a separate written request later.

Section 3, previous tax return adjustments. This is the box that unlocks the back years. Tick "Yes, adjust my previous tax returns for all applicable years" and the CRA will review up to 10 prior years once you are approved. A 2026 application can reach back to 2016. If you miss the box, you can still ask later through Change my return or Form T1-ADJ, but ticking it now is simpler.

Section 4, authorization. Your signature, or your legal representative's. If someone signs for you under a power of attorney, they sign as your legal representative; our power of attorney guide for caregivers explains what that role covers.

What conditions qualify for the disability tax credit in Canada?

No condition qualifies on its own. The CRA looks at whether the impairment is severe and prolonged, and it uses three tests, any one of which is enough (CRA, Who is eligible, updated August 19, 2026):

• A marked restriction in one activity. You cannot do it, or it takes you at least three times as long as someone your age without the impairment, even with medication, therapy and devices. It has to be that way all or almost all of the time (the CRA uses 90%). It also has to last, or be expected to last, at least 12 months in a row.
• The cumulative effect of significant limitations in two or more activities that together add up to a marked restriction.
• Life-sustaining therapy that supports a vital function, at least twice a week and averaging 14 hours a week. Dialysis is the classic example. People with type 1 diabetes are treated as meeting the time test automatically.

The activities the CRA assesses are walking, mental functions for everyday life, dressing, feeding, eliminating, hearing, speaking and vision.

For the conditions that come up most often after 65, here is how the CRA treats them:

• Dementia is not automatic. It qualifies when it markedly restricts mental functions such as memory, judgment, recognizing safety risks or handling simple transactions. Families often start this conversation early; our post on whether people with dementia know they have it covers what that stage looks like.
• Arthritis and mobility limits qualify through their effect on walking, dressing or feeding. The CRA's walking examples include being unable to walk about 100 metres, or needing a wheelchair even for short distances.
• Hearing and vision loss must still meet the severe and prolonged test after hearing aids or glasses are taken into account.

If you are unsure, the form is how you find out. Statistics Canada found that only about 15% of people aged 65 to 74 with a disability had claimed the credit at all (2015 to 2017 tax data). That suggests a lot of eligible people never get as far as the form.

How long does it take for a T2201 to be approved, and what does it cost?

The CRA's own target is a decision within 8 weeks of receiving your form, met 95% of the time under its 2026-27 service standards. In practice it can run longer. The Taxpayers' Ombudsperson reported waits of up to 15 weeks in a review updated August 2026. The 8-week target also does not apply if the CRA has to contact your practitioner for more detail, which is another reason a specific, well-filled Part B pays off.

The CRA charges nothing to process the form. Your practitioner may charge a fee, and the CRA does not cover it. Fees vary. The Ontario Medical Association's 2026 suggested fee guide sets a $150 minimum for the T2201, and published clinic schedules in Ontario list $160 to about $170. Keep the receipt: the fee can count as a medical expense on your tax return.

How much disability tax credit will I get?

For 2026 the federal disability amount is $10,341, which works out to about $1,448 off your federal income tax. Each province adds its own amount on top. The credit is non-refundable, so it reduces tax you owe rather than paying out cash.

Sources: CRA indexation table (May 2026); CRA provincial tax pages (September 2026); Province of BC; Alberta 2026 Fiscal Plan. Quebec runs its own version, an amount for a severe and prolonged impairment of $4,208 for 2026, claimed with a separate Quebec form.

Because it is non-refundable, a senior whose income is low enough that little tax is owed may see only a small benefit on their own return. That is what the transfer rule is for. Any unused amount can go to a spouse or common-law partner (line 32600 on their return) or to an adult child or other relative who supports you (line 31800). For a child to claim it, you need to depend on them for at least one of food, shelter or clothing on a regular basis.

The back years are where the numbers grow. Ten years of unused credit, transferred to a working son or daughter, can add up to a meaningful refund. The CRA only refunds tax that was actually paid in those years, so the total depends on the family's situation.

Approved for the disability tax credit, now what?

Your notice of determination will say which years you are eligible for. From there:

• Claim the disability amount on your return at line 31600, or have the supporting family member claim the transfer. If you ticked the box in Part A, the CRA adjusts your own past returns. Transfers to a spouse or child for past years usually need a separate adjustment request.
• Check the Canada Caregiver Credit. A son or daughter who supports you can often claim it as well, and an approved T2201 satisfies the medical documentation. Our Canada Caregiver Tax Credit guide walks through the lines and amounts.
• Know what approval does not change after 65. The Home Accessibility Tax Credit already applies to anyone 65 or older, so approval adds nothing new there. See our Home Accessibility Tax Credit guide if you are planning renovations. The Canada Disability Benefit is for ages 18 to 64 only. A new Registered Disability Savings Plan cannot be opened after the year you turn 59.
• Watch the nursing home rule. If you or a family member claim full-time nursing home fees as a medical expense, the CRA generally makes you choose between that and the disability amount for the same person. A tax preparer can run both ways.

Frequently asked questions

Is the disability tax credit a monthly payment?

The Disability Tax Credit is not a monthly cheque. It lowers the income tax you owe, and any part you cannot use can be transferred to a spouse or a child who supports you. It is claimed once a year on your income tax return, and the CRA applies it against federal and provincial tax for each eligible year.

How does the disability tax credit work?

A medical practitioner certifies on Form T2201 that you have a severe and prolonged impairment. The CRA reviews the form and issues a notice of determination listing the eligible years. You then claim the disability amount on your return for those years, and the CRA can adjust up to 10 past returns if you asked it to.

Who can claim the disability tax credit?

The person with the impairment claims it first. Any unused amount can be transferred to a spouse or common-law partner, or to an adult child or another close relative who supports them with food, shelter or clothing. The supporting person is named in Part A, section 2 of the form.

Is it worth claiming a disability tax credit?

For most eligible people, yes. The 2026 federal amount alone is worth about $1,448 in tax, provinces add more, and an approval can reach back 10 years. The main costs are a practitioner's fee, often around $150 to $170, and a few hours of your time. Applying is free.

Before you start

Download the current form or open the digital application today, not a saved copy. Decide who will claim any transferred amount and put their name in Part A. Tick the box for past years. Then book the practitioner who can sign for your category, and bring your plain-language notes.
