Eligibility
The DTC is a non-refundable federal tax credit that reduces income taxes for Canadians with severe and prolonged physical or mental impairments. The 2026 federal base credit is $1,481. Provincial credits are added on top. Eligible Canadians can also claim retroactively for up to 10 years, potentially recovering tens of thousands of dollars in previously paid taxes.
You may qualify if you have a severe and prolonged impairment (12+ months) that markedly restricts one or more of the qualifying daily living activities: vision, speaking, hearing, walking, eliminating, feeding, dressing, mental functions, or life-sustaining therapy. You need a medical practitioner to certify the impairment on Form T2201.
"Markedly restricts" means the activity either cannot be performed at all, or takes at least 3 times longer than someone without the impairment, and this is the case all or substantially all of the time, meaning roughly 90% of the time. An impairment that only affects you occasionally or seasonally generally won't meet this threshold.
No. A diagnosis alone is not enough. What matters is how the condition functionally restricts your daily activities. Many people with disabilities don't qualify; conversely, some conditions not commonly thought of as "disabilities" do qualify when the functional restriction is severe enough. The focus is always on function, not diagnosis.
Possibly. CRA must consider the overall impact of the condition, including medication side effects and residual functional impairment, not just whether the condition is technically managed. If medication fully eliminates all restrictions, you likely won't qualify. But if significant restrictions remain despite medication, or if medication side effects themselves cause restriction, you may still qualify. This is one of the most contested areas in DTC law.
Application Process
Form T2201 is the Disability Tax Credit Certificate, the mandatory CRA form for applying for the DTC. Part A is completed by the applicant (or their legal representative). Part B is completed and signed by a qualified medical practitioner who certifies the nature and severity of your impairment. Without an approved T2201, there is no DTC. See our complete T2201 application guide for step-by-step instructions.
Different practitioners certify different impairment categories: doctors and nurse practitioners for most categories; optometrists for vision; audiologists for hearing; speech-language pathologists for speaking; physiotherapists and occupational therapists for walking and dressing; psychologists for mental functions. Specialists (psychiatrists, neurologists, rheumatologists, etc.) qualify as "medical doctors" for T2201 purposes.
Typically 6 to 8 weeks. During peak tax season (February through April), expect 10-12 weeks. You can check your application status through CRA My Account or by calling 1-800-959-8281. See our complete CRA approval timeline guide.
Usually no. Most DTC approvals cover a multi-year or indefinite period, specified in your Notice of Determination. Some conditions receive approvals with review dates, after which a new T2201 may be required. CRA will notify you when your approval is nearing expiry.
The DTC for yourself is claimed on line 31600 of your federal T1 return. The child supplement is included in this amount (automatically calculated). If transferring to a supporting person, they claim it on line 31800 using Schedule 2.
Amounts & Calculations
The 2026 federal base credit is $1,481 (15% of the $9,872 disability amount). Provincial credits add $599-$2,260 depending on your province. With a child under 18, an additional $864 federal supplement applies. Combined federal + provincial credits range from approximately $2,080 in Ontario to $3,741 in Quebec annually. See our province-by-province rate table.
For persons under 18, an additional disability amount of $5,758 applies in 2026, translating to an additional federal credit of approximately $864. This supplement is automatically added when a child's T2201 is approved and always transfers to the supporting parent or guardian (since the child has no income to use it against).
Having an approved DTC makes you (or your child) eligible for the Registered Disability Savings Plan (RDSP), arguably the most powerful secondary benefit of DTC approval. The RDSP offers federal matching grants of up to $3,500/year and bonds of up to $1,000/year for lower-income holders, with compound growth potential over decades. You must have an approved DTC to open an RDSP.
No. The DTC is a tax credit that reduces your taxes owed, it's not income and not taxable. The Child Disability Benefit is also tax-free. Retroactive DTC refunds are simply a return of taxes you overpaid in prior years, not income.
Retroactive Claims
Yes. CRA allows retroactive DTC claims for up to 10 years using Form T1-ADJ (Request for Adjustment). In 2026, you can go back to the 2016 tax year. Retroactive claims can total tens of thousands of dollars. See our complete retroactive claims guide for the step-by-step process.
T1-ADJ is CRA's "Request for Adjustment" form, used to amend previously filed tax returns. For DTC retroactive claims, you complete one T1-ADJ per year, changing line 31600 from $0 to the applicable DTC amount for that year. Submit with a copy of your approved T2201.
Yes. An estate trustee can file a T2201 and T1-ADJ adjustments on behalf of a deceased person, provided the years claimed fall within the 10-year window and the person qualified during their lifetime. Any resulting refunds flow to the estate and ultimately to the beneficiaries.
Denials & Appeals
You have 90 days to file a Notice of Objection with CRA's Appeals Division. Many denials are reversed on appeal with stronger, more specific medical documentation that directly addresses the reason for denial. If the Appeals Division also denies, you can escalate to the Tax Court of Canada. See our full DTC appeal guide.
You have 90 calendar days from the date on the Notice of Determination, not the date you received it, to file a formal Notice of Objection. This is a strict deadline. Missing it can forfeit your appeal rights at the CRA level, though Tax Court may still be an option in certain circumstances.
Yes. If new or better medical documentation is available, submitting a fresh T2201 can be faster than the formal appeal process. Reapplying is often the better strategy when the denial was due to insufficient documentation rather than a fundamental eligibility dispute.
Family & Caregiver
Yes. If the person with the disability has insufficient income to benefit from the credit, the unused portion can transfer to a qualifying supporting person, spouse, parent, grandparent, child, sibling, aunt/uncle, niece/nephew. The transfer is claimed on line 31800 of the supporting person's return, using Schedule 2. See our full caregiver benefits guide.
The Canada Caregiver Credit (CCC) is a federal credit worth up to $7,607 in 2026 (about $1,141 in credit value). It's available to those who support a dependent with a physical or mental impairment, even without an approved DTC. The CCC can be claimed in addition to the DTC transfer; they are not mutually exclusive.
The Child Disability Benefit (CDB) is a tax-free monthly payment to families of children under 18 who qualify for the DTC. The maximum for 2025-2026 is approximately $3,173 per year per child, issued alongside the Canada Child Benefit. It's income-tested and automatically recalculated retroactively when a DTC is approved.
No. The DTC is a federal tax credit. Provincial disability programs like ODSP (Ontario), AISH (Alberta), PWD (BC), and others are separate income support programs with different eligibility criteria, application processes, and payment structures. Some provincial programs do factor in DTC approval when assessing their own eligibility, but they are entirely distinct from the federal DTC.
