Disability Tax Credit for Mental Function Impairments: Financial Support for Adults and Seniors in Canada

Mental function impairments affect how individuals think, remember, and make decisions, key abilities that support independence and daily living. Conditions such as memory loss, dementia, brain injury, or severe depression can limit a person’s ability to plan, reason, or communicate clearly.
The Disability Tax Credit (DTC) offers financial relief for adults and seniors whose mental or cognitive impairments significantly restrict daily life. The DTC is a nonrefundable tax credit that reduces the amount of income tax you owe and, in some cases, allows you to receive retroactive refunds for years you were previously eligible.
At Count Smart, we help Canadians understand CRA requirements, prepare necessary documentation, and ensure your application demonstrates how these impairments impact your ability to function independently.
Do Mental Function Impairments Qualify for the Disability Tax Credit?
Yes. The Canada Revenue Agency (CRA) recognizes mental function impairments as eligible when they cause prolonged and significant restrictions that have lasted, or are expected to last, for at least 12 months.
You may qualify if your condition results in:
- Memory loss or confusion that affects safety or daily decision-making.
- Difficulty communicating, understanding, or processing information.
- Trouble organizing, focusing, or following multi-step tasks.
- Impaired judgment or reasoning, requiring supervision for personal care.
- Dependence on caregivers to manage finances, medication, or home routines.
The CRA focuses on how impairment affects day-to-day functioning, not just medical diagnosis. Even with medication or therapy, if the person requires supervision or constant support to perform essential tasks, they may qualify.
Common Conditions That May Qualify
Several mental or cognitive conditions may meet the CRA’s definition of a qualifying impairment:
- Alzheimer’s Disease or Dementia
- Traumatic Brain Injury (TBI)
- Stroke-related cognitive loss
- Severe depression or anxiety affecting concentration
- Bipolar disorder or schizophrenia
- Parkinson’s-related cognitive decline
Each case is assessed individually. The CRA evaluates how the condition impacts key mental functions such as memory, judgment, problem-solving, and communication, on a consistent basis.
How the Disability Tax Credit Helps
For adults and seniors, managing cognitive impairment can mean relying on caregivers, medications, and ongoing medical oversight. This support can be costly. The DTC provides relief through tax savings and potential retroactive refunds, helping offset care-related expenses.
Approved DTC applicants may be eligible for:
- Up to $1,958 to $3,169 per year in refunds (depending on province and tax return).
- Retroactive refunds for previous years (up to 10 years) if previously eligible but not approved.
- The option to transfer unused credits to a spouse, caregiver, or family member providing ongoing support.
These funds can ease the financial strain of hiring personal caregivers, purchasing safety equipment, or adapting to the home environment to enhance independence.
(Note: Refunds for children can range from approximately $3,000 to $5,300 depending on province and tax return.)
What Documentation Is Needed
The CRA requires detailed medical evidence that explains how mental function impairments limit everyday activities.
You’ll need:
- A Form T2201 Disability Tax Credit Certificate, completed by a qualified medical practitioner (e.g., neurologist, psychiatrist, or family doctor).
- Clinical or psychological assessments describing cognitive restrictions and care requirements.
- Notes or reports outlining daily assistance or supervision needs.
- Documentation showing treatment plans, medication use, or ongoing therapy.
Count Smart ensures your non-medical documentation is organized and consistent, helping your medical professional accurately describe your restrictions and daily care needs in the T2201 form.

FAQs: Mental Functions & Learning Disabilities and the Disability Tax Credit
The CRA accepts a wide range of mental function impairments, including dementia, Alzheimer’s, brain injury, stroke-related cognitive loss, schizophrenia, and severe mood disorders. Eligibility depends on how much these conditions restrict thinking, memory, or communication, not just the diagnosis itself.
A marked restriction means the person cannot perform basic mental functions of everyday life, such as remembering, problem-solving, or communicating without significant support, and that this limitation exists at least 90% of the time for a year or longer.
Yes. Seniors experiencing cognitive decline, confusion, or dependence on caregivers for safety or personal management often meet CRA’s criteria.
The application must show how these symptoms affect independent decision-making, communication, or daily self-care.
Documentation should include:
- A completed Form T2201 by a qualified medical practitioner.
- Neuropsychological or cognitive assessments describing the impairment.
Count Smart helps ensure your records are clearly presented before submission to the CRA.
Processing typically takes 8–12 weeks, depending on CRA’s workload and whether additional information is requested. Submitting a clear, well-supported claim with properly completed medical documentation helps reduce delays.
Denials are often due to incomplete or unclear medical descriptions. Count Smart can review your initial submission, identify gaps, and assist in strengthening your reapplication or appeal with better supporting evidence and organization.
