The Disability Tax Credit (DTC) is a non-refundable federal tax credit for Canadians with a severe and prolonged impairment in physical or mental functions. If you or a family member qualifies, the DTC reduces the amount of income tax you owe — and can be transferred to a supporting family member if the person with the disability doesn’t owe taxes. For 2024, the federal DTC amount is $9,872 (and $11,851 for those under 18), generating up to $1,481 in federal tax savings. Pathak Professional Corporation in Mississauga helps Ontario families navigate the DTC application process, retroactive claims, and related tax credits. Call 437-872-7399.

Disability Tax Credit Amounts — Federal and Ontario 2024

Note: Because the DTC is non-refundable, it can only reduce your tax payable to zero — it cannot generate a cash refund on its own. However, if the person with the disability has no tax owing, the DTC can be transferred to a supporting spouse, parent, grandparent, child, grandchild, sibling, aunt, uncle, niece, or nephew. Additionally, an approved DTC opens access to other benefits including the Registered Disability Savings Plan (RDSP) and Child Disability Benefit (CDB).

Who Qualifies for the Disability Tax Credit?

CRA requires that you have a severe and prolonged (lasting at least 12 months) impairment in one or more of the following categories:

• Vision: Visual acuity in both eyes with corrective lenses is 20/200 or worse, OR the widest diameter of your visual field is 20 degrees or less
• Speaking: Inability to speak so that others can understand in a quiet environment, taking 3 times longer than average for tasks involving speaking
• Hearing: Inability to hear so that others can be understood without lip-reading or signing; or taking 3 times longer than average
• Walking: Inability to walk, even with assistive devices, without taking 3 times longer than average
• Eliminating (bowel or bladder functions): Inability to manage these functions without taking 3 times longer, or requiring life-sustaining therapy
• Feeding: Inability to feed oneself or requiring 3 times longer than average
• Dressing: Inability to dress oneself or requiring 3 times longer than average
• Mental functions necessary for everyday life: Severe limitations in memory, problem-solving, goal-setting/judgment, adaptive functioning, or learning (this is the category that captures many autism, ADHD, mental illness, dementia, and brain injury cases)
• Life-sustaining therapy: Requires at least 14 hours per week of therapy to maintain vital functions (kidney dialysis, insulin therapy, etc.)
• Cumulative effect: Two or more moderate limitations in the above categories that together have a severe and prolonged effect

How to Apply for the DTC — Form T2201

Step 1: Complete Part A of Form T2201

Form T2201 (Disability Tax Credit Certificate) is the application. You (or your representative) complete Part A, which includes your personal information and the type of impairment.

Step 2: A Qualified Practitioner Completes Part B

A qualified medical practitioner must certify your impairment in Part B. The type of practitioner required depends on the category:

Step 3: Submit to CRA

Submit the completed T2201 to your local CRA tax centre (do not attach to your T1 return — submit separately). CRA reviews the application and notifies you of approval or denial within 4–8 weeks. CRA may also contact your medical practitioner directly for additional information.

Step 4: If Approved — Claim on Your Tax Return

CRA notifies you of the approval period (the years for which you are eligible). Claim the DTC on Schedule 1 of your T1 return (Line 31600 for yourself, Line 31800 for transfer to a supporting person). If you have prior years of eligibility within the approved period, request a T1 Adjustment for each year to claim retroactively.

DTC Transfer to Supporting Family Members

If the person with the disability has no tax payable (because their income is too low), the DTC can be transferred to a family member who financially supports them. The transfer is available to:

• Spouse or common-law partner
• Parent, grandparent, child, grandchild
• Brother, sister
• Aunt, uncle, niece, nephew

The supporting person must be resident in Canada and must be supporting the person with the disability. The unused DTC is calculated on the person with the disability’s return first — only the unused portion can be transferred. Our personal tax team maximizes the DTC transfer calculation to the family member with the highest marginal tax rate for maximum tax savings.

Retroactive DTC Claims — Up to 10 Years

Many Canadians don’t know they were eligible for the DTC in prior years. When CRA approves a T2201, the approval can go back to the year the disability began (or up to the beginning of the year you submit, depending on when the impairment started). You can then request adjustments to your prior year T1 returns for up to 10 years prior to the current year.

The retroactive DTC refund potential is significant:

• 10 years of federal DTC savings: approximately $9,872 × 15% × 10 years = $14,808 in retroactive federal refunds
• Plus provincial Ontario DTC refunds for each year
• Plus interest on refunds (CRA pays interest on overpayments)

Pathak Professional Corporation handles the full retroactive DTC claim process — T2201 application coordination, T1 Adjustment requests for prior years, and communication with CRA’s assessment team. Call 437-872-7399.

DTC and the Registered Disability Savings Plan (RDSP)

A CRA-approved DTC is the gateway to the Registered Disability Savings Plan (RDSP) — Canada’s tax-sheltered savings plan for people with disabilities. Key RDSP features:

• Canada Disability Savings Grant (CDSG): The federal government contributes up to $3,500/year in matching grants (on contributions up to $1,500/year), with additional $1,000/year for low-income families — up to $70,000 lifetime in grants
• Canada Disability Savings Bond (CDSB): Low-income families receive up to $1,000/year in government bonds with NO required contribution — up to $20,000 lifetime
• Tax-deferred growth: All RDSP investment growth is tax-sheltered until withdrawn
• Withdrawals in retirement: Taxed at the beneficiary’s marginal rate — typically low since they have limited income

If the DTC application is approved, opening an RDSP immediately locks in grant and bond eligibility for all future years. The RDSP is one of the most valuable financial tools available to Canadians with disabilities — but it requires a DTC approval first.

Other Benefits That Require a DTC Approval

• Child Disability Benefit (CDB): A tax-free monthly benefit for families caring for a child under 18 with a severe disability — up to $2,985/year (2024)
• Working Income Tax Benefit (Disability Supplement): Additional WITB amount for working individuals with a DTC-approved disability
• Home Accessibility Tax Credit (HATC): 15% credit on up to $20,000 in eligible renovation costs to improve accessibility for DTC-approved individuals
• Ontario Disability Support Program (ODSP): Provincial income support — DTC helps with applications but is not automatically cross-recognized

Frequently Asked Questions

What if my T2201 is denied by CRA?

If CRA denies your T2201, you can request an administrative review (reconsideration) within 90 days by sending a letter to CRA explaining why you believe you qualify, along with additional medical evidence. If the reconsideration is also denied, you can file a Notice of Objection and ultimately appeal to the Tax Court of Canada. Many initial denials are overturned on review when the T2201 Part B is completed more thoroughly or when additional documentation from the treating practitioner is provided. Pathak Professional Corporation assists Mississauga families with DTC reconsideration requests and objections. Call 437-872-7399.

Does ADHD qualify for the DTC?

ADHD can qualify for the DTC under the “mental functions necessary for everyday life” category, but the severity requirements are high — the impairment must be severe and prolonged. Mild to moderate ADHD typically does not qualify; severe ADHD that markedly restricts the ability to perform mental functions of everyday life (such that it takes 3+ times longer, or the person is unable to perform them even with appropriate therapy) may qualify. A psychologist (not just a family doctor) is generally required to certify mental function impairments for the DTC. Our team helps families understand whether their specific diagnosis and severity level is likely to qualify before completing the application. Call 437-872-7399.

Can I claim both the DTC and medical expenses for the same condition?

Yes — the DTC and the Medical Expense Tax Credit (METC) are separate credits that can both be claimed in the same year for the same condition. The DTC is a fixed credit for having the qualifying disability; the METC is based on actual eligible medical expenses paid (prescription drugs, medical devices, attendant care, therapy, etc.). Many Canadians with disabilities can claim both — and for DTC-approved individuals, some expenses that are normally not eligible for METC become eligible (such as up to $10,000 of attendant care costs). Our Mississauga tax team coordinates all disability-related credits to maximize your refund.

My parent was approved for the DTC but passed away last year — can we still claim retroactively?

Yes — a deceased person’s estate can still claim retroactive DTC credits for prior years through the estate’s T1 returns (terminal return and prior year amendments). The executor of the estate files for T1 Adjustments for prior years within the estate administration process. If the deceased had a supporting family member who could have claimed the DTC transfer in prior years, those transfers can also be claimed retroactively. The 10-year adjustment period applies from the date of the prior year returns, not the date of death. Pathak Professional Corporation provides estate tax services including retroactive DTC claims for deceased taxpayers. Call 437-872-7399.
