Disability Tax Credit
Last checked:
The Disability Tax Credit (DTC) lowers the income tax paid by a person with a severe and prolonged impairment, or by a family member who supports them. There is no age limit, so health problems that come with aging can qualify if they meet the rules. You apply once with form T2201, signed by a medical practitioner, and if approved you can ask the CRA to adjust up to 10 past years.

What is the disability tax credit?
The Disability Tax Credit is a non-refundable federal tax credit. It helps offset some of the extra costs of living with a severe and prolonged impairment by lowering the income tax you owe. It does not pay you money directly.
Being approved also matters for other reasons. The CRA says DTC eligibility may help you access other federal programs, including the Registered Disability Savings Plan, the Canada Disability Benefit, the Canada workers benefit disability supplement and the child disability benefit. People approved for the DTC can also claim the Home Accessibility Tax Credit at any age.
Can seniors get the disability tax credit?
Yes. There is no age limit and no income test. What counts is how your condition affects your daily life, not your diagnosis or your age. Conditions common in later life, such as vision loss, hearing loss, dementia, arthritis that limits walking, or the effects of a stroke, can qualify if they meet the rules below. Your practitioner compares you with people of a similar age who do not have the impairment.
Your impairment must be prolonged. That means it has lasted, or is expected to last, at least 12 months in a row.
You can qualify in one of three ways:
- A marked restriction in one area. Even with therapy, devices and medication, you cannot do the activity, or it takes you an inordinate amount of time (generally at least 3 times as long as someone of similar age without the impairment), all or substantially all of the time (generally 90% or more).
- Significant limitations in two or more areas that together have the same effect as a marked restriction, present at least 90% of the time.
- Life-sustaining therapy that supports a vital function, needed at least 2 times a week and for an average of at least 14 hours a week.
The areas are: vision, speaking, hearing, walking, eliminating (bowel or bladder functions), feeding, dressing and mental functions needed for everyday life, such as memory, judgment and problem-solving.
Some examples from the CRA: for vision, you are considered blind if your visual acuity is 20/200 or worse, or your field of vision is 20 degrees or less, in both eyes even with glasses or medication. For walking, an example is not being able to walk about 100 metres.
How much is the disability tax credit in 2026?
The disability amount for an adult 18 or older is $10,138 for the 2025 tax year and $10,341 for 2026. This is not the amount of money you get. The CRA multiplies it by the lowest federal tax rate, which is 14.5% for 2025 and 14% for 2026. That makes the federal tax saving up to about $1,470 for 2025 and $1,448 for 2026.
Because the credit only lowers tax, it helps most if you owe income tax. If you do not need all of it, it can be transferred to a supporting family member (see below).
How to apply for the disability tax credit (form T2201)
The form is free. Your medical practitioner may charge a fee to fill it in; you pay that fee, but you may be able to claim it as a medical expense. Medical doctors, nurse practitioners, optometrists, audiologists, occupational therapists, physiotherapists, psychologists and speech-language pathologists can certify the form.
You must choose one method, digital or paper, and use it for both parts of the application.
- Digital, Part A: Sign in to your CRA account, choose Individual account, then Benefits and credits, then Apply for DTC. Or call the CRA at 1-800-959-8281 (agent) or 1-800-463-4421 (automated). You will get a reference number that is good for up to 12 months.
- Digital, Part B: Give the reference number to your medical practitioner. They complete Part B in the CRA's digital application for medical practitioners, and the application goes to the CRA automatically.
- Paper, Part A: Print the latest Form T2201 and fill in Part A. Adults must sign their own application unless they have a legal representative.
- Paper, Part B: Your practitioner fills in Part B and signs it by hand. The CRA cannot process a form without a handwritten signature in Part B.
- Paper, sending it: Mail Parts A and B together to one of the CRA tax centres listed on the CRA's How to apply page: Jonquière Tax Centre, 2251 René-Lévesque Blvd, Jonquière QC G7S 5J2; Sudbury Tax Centre, PO Box 20000, Station A, Sudbury ON P3A 5C1; or Winnipeg Tax Centre, PO Box 14000, Station Main, Winnipeg MB R3C 3M2.
- In Part A, tick the box asking the CRA to adjust your past returns if you think you qualified in earlier years.
The CRA no longer accepts DTC applications sent through the Submit documents service in your CRA account. Use the digital application or mail.
Can I claim the disability tax credit for past years?
Yes. If you were eligible in earlier years but did not claim the credit, you can claim it for up to 10 years back. If you ticked the box on the application, the CRA adjusts your past returns for you. If you did not, you can ask the CRA in writing to adjust them, or change them yourself online using Change my return in your CRA account.
For a person whose condition began years ago, a back-claim can mean a sizeable refund. Ask your practitioner to give the date the impairment began, as best they can.
How to claim the credit once you are approved
The CRA sends a notice of determination that shows which years you are approved for. If it has no expiry date, you do not need to apply again. If it does, the CRA will remind you a year before and in the year it ends, and you will need to reapply.
- If you claim it yourself, use line 31600 of your return.
- If a supporting relative other than your spouse claims it, they use line 31800.
- If your spouse or common-law partner claims the unused part, they use line 32600.
What to do if your disability tax credit is denied
Read the notice of determination closely. It explains why the CRA decided you are not eligible. Then you have three options:
- Call the CRA at 1-800-959-8281 to talk about the decision and ask what information was missing.
- Ask for a review by mailing new medical information to the tax centre, such as reports or a letter from your practitioner that you have not sent before. Explain how your impairment affects daily activities, with examples of time taken and how often.
- File a formal objection within 90 days of the date of the notice of determination. You can use Form T400A, Notice of Objection.
Many refusals happen because the form does not show enough detail about daily effects. Ask your practitioner to describe what you cannot do, or how much longer it takes, rather than only naming the condition.
Canada Disability Benefit and RDSP: what changes after 64?
The Canada Disability Benefit is a federal monthly benefit for people approved for the DTC who are between 18 and 64 years old and have filed their tax return. It stops at 65. If you apply before then, you may get back payments for up to 24 months from the date the government gets your application, up to the month you turn 65. People who got a CDB payment between July 2025 and June 2026 are also to receive a one-time $150 supplemental payment.
A Registered Disability Savings Plan (RDSP) can be opened up to December 31 of the year the beneficiary turns 59, and contributions can be made until the end of that year. Government grants and bonds stop after December 31 of the year the beneficiary turns 49. For most people already retired, an RDSP is less useful, but it can matter for a younger spouse or an adult child with a disability.
Things people often miss
- You do not need to pay a company to apply. The CRA application is free; only your practitioner may charge a fee.
- Age-related conditions can qualify. The test is how much the condition limits you, not why.
- If you live with a family member who pays your bills, the credit you cannot use may lower their tax instead.
- If you are approved, you can also claim the Home Accessibility Tax Credit, even before age 65.
- Approval with an expiry date means you must reapply. Watch for the CRA's reminder letter.

The federal disability amount for adults is $10,341 for 2026 ($10,138 for 2025). Multiplied by the 14% federal rate for 2026, it can lower federal tax by up to about $1,448.
