Disability Tax Credit in Canada: Eligibility, Applications, Retroactive Claims and Tax-Planning Opportunities

Living with a disability or supporting a family member with a disability can create significant financial costs. Canada’s Disability Tax Credit, commonly called the DTC, is intended to provide some tax relief and may also open the door to other valuable government programs, including the Registered Disability Savings Plan, Child Disability Benefit and Canada Disability Benefit.

However, eligibility is based primarily on the effects of the impairment on everyday activities, not simply on having a particular medical diagnosis.

This guide explains who may qualify, how to apply, how the Canada Revenue Agency reviews applications, what can be claimed after approval, and how families can coordinate the DTC with medical expenses, caregiver claims and other disability-related benefits.

What Is the Disability Tax Credit?

The Disability Tax Credit is a non-refundable tax credit available to an eligible individual with a severe and prolonged impairment or, in certain circumstances, a supporting family member.

A non-refundable credit can reduce income tax payable, but it does not by itself create a refund when no tax was otherwise payable. If the individual with the disability cannot use the full credit, some or all of the unused amounts may potentially be transferred to an eligible supporting family member.

For the 2025 tax year, the federal disability amount for an adult is $10,138. An additional supplement may be available for an eligible person under 18, subject to reductions for certain childcare and attendant-care expenses. Provincial or territorial disability amounts may also apply.

The disability amount is multiplied by the applicable federal and provincial non-refundable tax-credit rates. Therefore, the amount shown on the tax return is not the amount of cash received.

Who Is Eligible for the DISABILITY TAX CREDIT?

A person may qualify when an authorized medical practitioner certifies that the person:

• Has a marked restriction in one eligible category;
• Has significant limitations in two or more eligible categories whose combined effect is equivalent to a marked restriction; or
• Requires qualifying life-sustaining therapy.

The impairment must also be prolonged, meaning it has lasted or is expected to last for a continuous period of at least 12 months.

Eligible functional categories

The DTC application considers the effects of an impairment in areas that include:

• Walking;
• Speaking;
• Hearing;
• Dressing;
• Feeding;
• Eliminating, including bowel or bladder functions;
• Mental functions necessary for everyday life;
• Vision; and
• Life-sustaining therapy.

A person may also qualify under the cumulative-effect rules when significant limitations in two or more categories exist together substantially all of the time.

How to Apply for the Disability Tax Credit

The DTC application is made using Form T2201, Disability Tax Credit Certificate.

The form has two sections:

• Part A, completed by the individual with the impairment or their legal representative; and
• Part B, completed by an authorized medical practitioner.

The application can be completed digitally or by paper. For a digital application, the applicant completes Part A through their CRA account and receives a reference number. The reference number is then provided to the medical practitioner, who completes and submits Part B electronically.

A paper application may also be completed and mailed to the CRA. The applicant should use the most recent version of Form T2201. Effective September 8, 2026, the CRA will no longer accept versions of Form T2201 from before 2023.

The CRA recommends using the designated online DTC application process rather than uploading a new application through the general “Submit documents” function in a CRA account.

Practical tips for completing Form T2201

The medical portion should explain the functional impact of the impairment in clear, specific terms.

Useful information may include:

• What activities the person cannot perform;
• How long routine activities take;
• How frequently assistance or supervision is required;
• Whether reminders, prompting or intervention are needed;
• Safety risks;
• The effects of medication, therapy and assistive devices;
• Whether limitations vary from day to day;
• When the impairment and its functional effects began; and
• Whether the limitations are expected to improve.

General statements such as “the patient has difficulty walking” may not be enough. A more useful explanation would describe how far the person can walk, how long it takes, whether they must stop, whether assistance is required and how the limitation compares with someone of a similar age.

Applicants should review the completed form before submission and keep a copy.

How Does the CRA Approval Process Work?

After receiving the complete application, the CRA compares the information provided by the medical practitioner with the DTC eligibility criteria.

The review generally follows these steps:

1. The CRA receives Parts A and B of the application.
2. The CRA reviews the medical information and functional limitations.
3. If more information is required, the CRA may contact the medical practitioner.
4. The practitioner is generally given 60 business days to respond.
5. The CRA reviews any additional information and issues a written notice of determination.

Applicants can generally monitor the status through the Progress Tracker in their CRA account.

Possible CRA decisions

The CRA may:

• Approve the application indefinitely;
• Approve it for a limited period;
• Approve only certain previous or future years; or
• Deny the application.

The notice of determination will identify the years for which the person is eligible. When approval has an expiry date, the individual may need to reapply. The CRA states that it normally provides advance notice before eligibility expires.

What if the application is denied?

A denial is not necessarily the end of the process.

The applicant should compare the CRA’s reasons with the information included on Form T2201. Options may include:

• Requesting a review and submitting additional medical information;
• Providing an updated report or letter from a practitioner familiar with the impairment;
• Filing a formal notice of objection; or
• Reapplying if the condition or available medical evidence has changed.

A formal income tax objection generally must be filed within 90 days of the notice of determination.

The response should directly address the CRA’s reasons for denial. Resubmitting the same general information without addressing the disputed eligibility criteria may not change the outcome.

How Do You Claim the Disability Tax Credit After Approval?

Once approved, the disability amount is claimed on the individual’s income tax return.

Common federal tax-return lines include:

• Line 31600: Disability amount for self;
• Line 31800: Disability amount transferred from a dependant; and
• Line 32600: Amounts transferred from a spouse or common-law partner, which may include an unused disability amount.

The DTC should not be claimed for a year outside the eligibility period shown in the CRA’s notice of determination.

Can the Disability Tax Credit Be Transferred?

Yes. When the eligible individual cannot use all of the disability amount because they do not have enough tax payable, the unused amount may be transferable to a qualifying supporting family member.

Depending on the relationship and circumstances, the supporting person may include the individual’s:

• Spouse or common-law partner;
• Parent or grandparent;
• Child or grandchild;
• Brother or sister;
• Aunt or uncle;
• Niece or nephew; or
• Certain relatives of the individual’s spouse or common-law partner.

The supporting person must generally have supported the individual with necessities such as food, shelter or clothing. The availability of the transfer can also be affected by the dependant’s income and by other amounts claimed for that dependant.

A transfer does not mean that two people can both claim the full credit. The eligible person uses the amount required to reduce their tax, and only the remaining portion may be transferred.

Where more than one family member provides support, the family should coordinate the claim to avoid duplication.

Can the Disability Tax Credit Be Claimed for Previous Years?

Yes. The CRA may approve the DTC retroactively if the medical evidence supports that the person met the eligibility conditions in earlier years.

Taxpayers can generally request adjustments for up to 10 previous calendar years, subject to the CRA’s taxpayer-relief and reassessment rules.

For example, an application approved in 2026 could potentially result in adjustments as far back as the 2016 tax year, provided the notice of determination confirms eligibility for those years.

The prior-year adjustments may include:

• The disability amount for the eligible individual;
• A transfer to a supporting family member;
• The disability supplement for a child under 18;
• The Canada caregiver credit;
• Eligible medical expenses;
• The Canada Workers Benefit disability supplement; and
• Related provincial or territorial credits.

When completing Form T2201, the applicant can authorize the CRA to automatically adjust eligible previous returns. Alternatively, adjustments can be requested through the individual’s CRA account or by filing Form T1-ADJ.

The CRA will issue notices of reassessment after processing approved prior-year changes.

Review the whole family’s returns

Automatic adjustments may not always produce the best family result.

For example, the CRA may apply the disability amount to the individual with the impairment even though a supporting family member could have used the transferred amount more effectively. Similarly, medical expenses may produce a better result when claimed by the lower-income spouse.

After retroactive approval, it is important to review the tax returns of the individual, spouse, parents and other supporting family members for every approved year.

Disability Tax Credit Versus Medical Expenses

The DTC and the Medical Expense Tax Credit are separate claims.

The DTC is a fixed non-refundable credit based on eligibility for a severe and prolonged impairment. Medical expenses are based on eligible amounts actually paid during a qualifying 12-month period.

A person may be entitled to:

• The DTC only;
• Medical expenses only; or
• Both claims.

Attendant Care and Paying a Family Member

Families sometimes pay a relative to provide regular personal care, supervision or assistance.

Payments to a family member may qualify as attendant-care medical expenses, but only when all relevant conditions are satisfied.

The CRA states that amounts paid to an attendant can generally be claimed only when the attendant:

• Is not the patient’s spouse or common-law partner; and
• Was at least 18 years old when paid.

The services must also qualify as attendant care. This generally involves personal tasks the individual cannot perform independently, rather than ordinary family support or companionship.

Eligible services may include:

• Personal care;
• Food preparation;
• Housekeeping for the person’s personal living area;
• Laundry;
• Health-care assistance;
• Transportation;
• Supervision; and
• Security in appropriate circumstances.

For in-home attendant care, the person receiving care must generally either qualify for the DTC or have written certification from a medical practitioner stating that the services are necessary.

Keep proper documentation

Where a family member is paid, maintain:

• A written care agreement;
• A description of the services;
• Timesheets or a schedule of care;
• Proof of payment;
• Receipts;
• The attendant’s social insurance number;
• Medical certification where required; and
• Payroll records when an employer-employee relationship exists.

The CRA notes that a privately hired attendant will often be considered an employee. That may create responsibilities for payroll deductions, T4 reporting, workers’ compensation, employment standards and other employer obligations.

The family member receiving the payment must generally report it as taxable employment or business income, depending on the relationship.

Do not call attendant-care wages a “caregiver expense”

There is no general deduction called a “caregiver expense.”

The tax treatment may instead involve:

1. Medical expenses for attendant care, based on amounts actually paid; and/or
2. The Canada caregiver credit, based on supporting an infirm spouse or dependant.

These rules are separate and should not be confused.

Canada Caregiver Credit

The Canada caregiver credit is a non-refundable credit for an individual who supports a spouse, common-law partner or dependant with a physical or mental infirmity.

The amount depends on:

• The relationship;
• The dependant’s age;
• The dependant’s net income;
• Whether the dependant lives with the claimant;
• Other credits claimed; and
• The claimant’s family circumstances.

For 2025, the maximum federal caregiver amount for certain adult dependants can be as high as $8,601, while other caregiver components may be lower. These figures are indexed annually.

Disability Tax Credit approval is not always required for the caregiver credit. However, the CRA may request a signed statement from a medical practitioner confirming when the infirmity began and how long it is expected to last. A separate medical statement is generally not required for a period already covered by an approved T2201.

Claiming Both the Disability Tax Credit and Attendant-Care Expenses

Special restrictions may apply when claiming both the disability amount and attendant-care or nursing-home expenses for the same person.

Depending on the type of care, location and certification, a taxpayer may be able to claim:

• The full DTC and a limited amount of attendant-care expenses;
• The attendant-care expenses without the DTC;
• The DTC and the salary portion of certain facility fees; or
• Full-time nursing-home expenses without claiming the DTC for that person.

The rules are detailed and can produce materially different results. Before filing, compare the available alternatives rather than assuming both claims can always be taken in full.

Disability Supports Deduction

The Disability Supports Deduction is separate from both the Disability Tax Credit and the Medical Expense Tax Credit.

A person with an impairment may be able to deduct qualifying expenses incurred to:

• Work;
• Attend school; or
• Conduct grant-funded research.

Only the person with the disability can claim this deduction. Because it is a deduction from income rather than a non-refundable credit, it may produce a different tax result.

An expense generally cannot be claimed both as a disability-support expense and as a medical expense.

Registered Disability Savings Plan (RDSP)

Disability Tax Credit approval may allow the individual to become the beneficiary of a Registered Disability Savings Plan, or RDSP. 

Please refer to Registered Disability Savings Plan blog for more details.

Other Benefits Connected to Disability Tax Credit Approval

Disability Tax Credit approval may provide access to, or improve eligibility for, several other programs.

Child Disability Benefit

The Child Disability Benefit is a tax-free monthly benefit for families caring for a child under 18 who qualifies for the DTC. It is generally calculated based on family net income and is paid with the Canada Child Benefit.

Canada Disability Benefit

The Canada Disability Benefit provides direct financial support to qualifying low-income persons with disabilities between ages 18 and 64.

The first month of eligibility was June 2025, and payments began in July 2025. Eligibility requires, among other conditions, DTC approval and the filing of required income tax returns by the individual and their spouse or common-law partner.

Canada Workers Benefit disability supplement

An eligible working individual with lower income may qualify for the disability supplement to the Canada Workers Benefit. DTC approval is generally required.

Home Accessibility Tax Credit

Eligible renovation expenses may qualify for the Home Accessibility Tax Credit where the renovation improves access, mobility, safety or functionality for an eligible person.

Some expenditures may qualify for both the Home Accessibility Tax Credit and the Medical Expense Tax Credit, provided all conditions for both claims are met.

Multigenerational Home Renovation Tax Credit

Certain renovations that create a qualifying secondary unit for an adult aged 65 or older, or an adult who qualifies for the DTC, may be eligible for this refundable credit.

Provincial and territorial programs

Disability Tax Credit approval may also support access to provincial disability credits, benefits, property-tax programs, transit programs and other assistance. Rules vary by province and municipality.

Tax-Planning Checklist After Disability Tax Credit Approval

Approval should trigger a broader review rather than simply adding one line to the current-year tax return.

Consider the following:

1. Confirm the exact years approved in the notice of determination.
2. Review up to 10 prior tax years.
3. Determine whether the eligible person can use the full disability amount.
4. Identify supporting family members who may qualify for a transfer.
5. Compare transfers between spouses, parents and other eligible supporters.
6. Review the Canada caregiver credit.
7. Review medical and attendant-care expenses.
8. Compare whether medical expenses should be claimed by the lower-income spouse.
9. Determine whether a paid family caregiver is an employee.
10. Consider opening or contributing to an RDSP.
11. Review eligibility for the Child Disability Benefit, Canada Disability Benefit and Canada Workers Benefit disability supplement.
12. Review accessibility-renovation credits and provincial programs.
13. Monitor the expiry date of the DTC approval.
14. Keep medical, payment and support documentation.

Final Thoughts

The Disability Tax Credit can provide meaningful tax relief, but its value often goes well beyond the annual disability amount.

Approval may lead to:

• Refunds for prior years;
• Transfers to supporting family members;
• Caregiver credits;
• Attendant-care and medical-expense claims;
• RDSP grants and bonds;
• Child Disability Benefit payments;
• Canada Disability Benefit payments; and
• Other federal and provincial assistance.

The strongest applications focus on the actual functional effects of the impairment, supported by specific and consistent medical information.

After approval, the individual and their family should review the entire household’s tax position. Properly coordinating the disability amount, transfers, caregiver credits, medical expenses and disability-related programs can produce a much better result than treating the DTC as a single tax-return entry.
