Is there a Disability Tax Credit calculator?
There is no official CRA calculator for the Disability Tax Credit, because the credit is not a set amount. It depends on your taxes and your situation. What you can check in about a minute is whether you may qualify at all. That is what the checker above does, in plain English.
Understanding the Disability Tax Credit
What it is
The Disability Tax Credit, or DTC, is a federal tax credit that can reduce the income tax a person with a disability, or a supporting family member, may have to pay. The Canada Revenue Agency decides from how a condition affects daily life, not from the diagnosis alone. The official rules live on the CRA page: Disability Tax Credit, Canada Revenue Agency.
Who it helps
Adults and children whose condition markedly affects things like walking, speaking, hearing, seeing, feeding, dressing, or the mental functions of everyday life, most of the time, over a prolonged period. Approval is also the key that opens the RDSP and the Canada Disability Benefit.
Common mistakes
Describing the diagnosis instead of daily life on the application. Assuming a condition does not count without checking. And forgetting that eligible past years can often be claimed, up to 10 years back.

Disability Tax Credit questions, answered.
What is the Disability Tax Credit?
The Disability Tax Credit (DTC) is a non-refundable tax credit for Canadians with a severe and prolonged impairment in physical or mental functions. You apply with Form T2201, and only the CRA can approve it. The DTC cuts the tax you owe every year. It is also the key that unlocks the RDSP, including its grants and bonds.
How long does an impairment need to last?
An impairment counts when it is severe and prolonged. That means it has lasted, or is expected to last, at least 12 continuous months. Short-term conditions generally do not meet this test.
Does the DTC automatically give me an RDSP?
No. You must open the RDSP separately, but DTC eligibility is required to open one. Think of the DTC as the key, and the RDSP as the room it unlocks.
Who certifies Form T2201?
A qualified medical practitioner, such as a doctor or nurse practitioner, must certify the impairment on Form T2201 before the CRA will review it. Other qualified practitioners can certify for certain functions. A common mistake on the form is naming the condition without describing how it limits daily life. The form needs function in detail, not just a diagnosis.
Can children qualify?
Yes. Children can qualify for the DTC, and an RDSP can be opened on their behalf. This is often where the biggest lifetime benefit sits, because grants and bonds can accrue for decades.
Does it cost anything to apply?
The CRA charges no fee for a DTC application. A medical practitioner may charge a fee to complete the certification portion of Form T2201.
Can I get the DTC for a mental health condition?
Yes, when the effects meet the test. CRA assesses mental functions necessary for everyday life, such as memory and judgment, and whether they are markedly restricted all or substantially all of the time. The diagnosis alone is not enough: Form T2201 has to describe what daily life actually looks like with the condition.
What are the most common reasons DTC applications get rejected?
Myth: a DTC denial is final, answered honestly: it rarely is. The most common reason is a thin Form T2201 that names a condition without describing functional limitations in enough detail. Other reasons include no clear evidence the impairment will last 12 months. Many rejections turn into approvals once stronger medical detail is submitted.
How long does DTC approval last?
The CRA grants some approvals indefinitely and some temporarily. Temporary approvals have an end date printed on the notice of determination. If yours is temporary, reapply before it expires if the impairment continues.
