The Disability Tax Credit reduces your federal income tax if you have a severe and prolonged impairment
The Disability Tax Credit (DTC) is a federal tax reduction, not a payment. If you are approved, you can reduce the income tax you owe to the Canada Revenue Agency (CRA). The credit does not pay you money directly — it lowers your tax bill. You must have a severe and prolonged mental or physical impairment that restricts your ability to perform basic daily activities. The impairment must have lasted, or be expected to last, for at least 12 consecutive months.
The amount of the credit depends on your net income and whether you transfer unused credits to a spouse, common-law partner, or parent. In 2024, the maximum federal credit is approximately $2,911 if you claim it yourself, but the actual reduction in your tax bill varies. You must file a Form T2201 (Disability Tax Credit Certificate) with the CRA and have it approved before you can claim the credit on your tax return.
Key Takeaways
- The Disability Tax Credit reduces your federal income tax owed, not a separate payment, and requires CRA approval of Form T2201 before you can claim it.
- Your impairment must be severe and prolonged (expected to last 12 months or more) and must significantly restrict your ability to perform basic daily activities like walking, seeing, hearing, or self-care.
- You can transfer unused credits to a spouse, common-law partner, or parent, which may result in a larger tax reduction if they have higher income.
- The CRA processes T2201 applications in roughly 4 to 6 weeks, though complex cases may take longer, and you can reapply if your first process is denied.
Who can claim the Disability Tax Credit
You must meet two conditions: you must be a Canadian resident for tax purposes, and you must have a severe and prolonged impairment. The CRA defines "severe" as a restriction that markedly restricts your ability to perform a basic activity of daily living. "Prolonged" means the condition has lasted, or is expected to last, for at least 12 consecutive months.
Basic activities of daily living include walking, seeing, hearing, speaking, feeding yourself, dressing yourself, toileting, and performing mental functions needed for everyday life. You do not need to be unable to do these things entirely — you need to be markedly restricted. For example, if you can walk only a short distance before severe pain forces you to stop, or if you need someone to help you dress, you may meet the threshold. The impairment can be physical or mental, and you can claim the credit even if you are working.
You cannot claim the credit if your impairment is temporary. If you had surgery and expect to recover within 12 months, you do not meet the prolonged requirement. If your condition is permanent or expected to last longer than 12 months, you may be may be able to access.
how the process works for the Disability Tax Credit
Start by obtaining Form T2201 from the CRA website or by calling 1-800-959-5525. You will also need a medical professional to complete the form. The medical professional must be a doctor, nurse practitioner, optometrist (for vision impairments), audiologist (for hearing impairments), psychologist, or occupational therapist, depending on your condition. Some provinces accept other professionals — check the CRA website for your province's list.
You and the medical professional both sign the form. The professional describes your impairment, how it affects your daily activities, and when it began. Be specific: instead of writing "I have back pain," explain "I cannot sit for more than 20 minutes without severe pain that forces me to lie down." The CRA uses these details to decide whether your impairment meets the "marked restriction" threshold.
Mail the completed Form T2201 to the CRA address listed on the form, or upload it through My Account on the CRA website if you have registered. Keep a copy for your records. The CRA will send you a notice of assessment within roughly 4 to 6 weeks, though some applications take longer. If approved, you will receive a letter stating the approval period — usually retroactive to the year you applied, and valid for up to 10 years.
What happens after approval
Once the CRA approves your Form T2201, you can claim the Disability Tax Credit on your tax return for the year you applied and any previous years back to when your impairment began (up to 10 years prior). You claim it on Schedule 11 of your tax return. If you have no tax owing or a low income, you may have no tax to reduce — in that case, you can transfer unused credits to a spouse, common-law partner, or parent.
If you transfer the credit to a spouse or common-law partner, they claim it on their return and it reduces their tax bill. If you transfer it to a parent, the parent claims it on their return. This is often the best option if you have little or no income but your spouse or parent has higher income — the credit will reduce their tax bill instead of yours.
Your approval is valid for the period stated in the CRA letter. Before it expires, you can explore to renew it by submitting a new Form T2201. If your condition improves or you no longer meet the criteria, you should not claim the credit.
Denied applications and reapplication
If the CRA denies your process, you will receive a letter explaining why. Common reasons include: the impairment does not markedly restrict a basic activity of daily living, the medical evidence does not support the claim, or the condition is not expected to last 12 months. Read the letter carefully to understand which part of the definition you did not meet.
You can reapply. Gather more detailed medical evidence, ask your doctor to be more specific about how the impairment affects your daily life, or wait until your condition has clearly lasted 12 months if timing was the issue. You can also file a Notice of Objection within 90 days of the denial letter if you believe the CRA made an error. Include new medical evidence or a detailed explanation of why you believe you meet the criteria.
If you object and the CRA still denies your claim, you can appeal to the Tax Court of Canada. This process is more formal and may require legal help. Many people find it useful to consult a disability advocate or tax professional before appealing.
How the credit affects your income and benefits
The Disability Tax Credit itself does not count as income and does not affect your may be able to access for other programs like SSDI, provincial disability support, or means-tested benefits. However, if you transfer the credit to a spouse or parent, the tax reduction they receive does not change their income for benefit purposes either — it is a tax reduction, not new income.
If you are receiving SSDI or other disability benefits, claiming the Disability Tax Credit will not reduce those benefits. The two programs operate separately. The credit is a federal tax measure; SSDI is a separate federal benefit program. Reporting the credit on your tax return does not trigger a review of your SSDI case.

Frequently Asked Questions
Can I claim the Disability Tax Credit if I am working?
Yes. The credit is based on the severity of your impairment, not your employment status. You can work full-time, part-time, or not at all and still claim the credit if your impairment markedly restricts a basic daily activity.
What if my doctor says I am disabled but the CRA denies my process?
The CRA uses a specific legal definition of "marked restriction" that is stricter than a medical diagnosis of disability. A doctor may say you are disabled for work purposes, but the CRA may find that you do not meet the tax credit threshold. Ask your doctor to describe exactly how the impairment affects your ability to walk, see, hear, feed yourself, dress, or think — the CRA focuses on these specific activities.
Can I claim the credit for years before I applied?
Yes, back to 10 years prior. If your impairment began in 2018 but you applied in 2024, the CRA can approve the credit for 2018 through 2024 if your condition meets the criteria for all those years. You will need to file amended tax returns for previous years to claim the credit.
What if I transfer the credit to my parent but they do not want to claim it?
You can transfer it to them, but they must claim it on their tax return for it to reduce their tax bill. If they choose not to claim it, the credit is not used. You cannot claim it yourself if you have already transferred it. Discuss with your parent before transferring to make sure they are willing to claim it.
Does the Disability Tax Credit expire?
Your approval expires on the date stated in the CRA letter, usually 10 years after approval. Before it expires, you can explore to renew by submitting a new Form T2201. If you do not renew, you cannot claim the credit after the expiry date.
