Disability Tax Credit (DTC)
Last verified: April 2026. Always confirm details on the official page.
Quick fit
- Not based on diagnosis — based on functional impairment
- Restriction must last 12 months or more
- Federal program, separate from OAP and SSAH
- Not income tested
- Retroactive up to 10 years, depending on the years CRA approves as eligible
- DTC approval is required for RDSP access and Child Disability Benefit eligibility
The DTC is a federal tax credit from the (Canada Revenue Agency). The credit itself may not save you much tax. The real reason to apply: DTC approval is required to open an (government matching up to $3,500/year) and is a prerequisite for (Child Disability Benefit) payments ($3,411/year tax free for the July 2025 to June 2026 period). CDB payments also depend on Canada Child Benefit eligibility. These downstream benefits make the DTC worth doing for many families.
Apply now. Do not wait until tax season. Do not assume your income is too low. The RDSP bonds are specifically for lower income families.
How do I know if my child qualifies for the DTC
Approval is based on functional impairment, not diagnosis. Your child needs a severe and prolonged restriction in daily life, expected to last 12 months or more, certified by a medical practitioner on CRA Form T2201. Not income tested.
- Your child has a severe and prolonged impairment in physical or mental functions that causes a marked restriction in daily life
- The restriction must be expected to last 12 months or more
- A medical practitioner must certify this on CRA Form T2201
- Not income tested
- Federal CRA program, separate from OAP and SSAH (decided on its own criteria)
Important
Approval is not automatic just because your child has an autism diagnosis. CRA looks at how the impairment affects daily functioning, not the diagnosis itself. The way your practitioner fills out Part B of the T2201 matters a lot.
How do I fill out the T2201 form for the DTC
- Fill out Part A. This is the family section. Basic information about your child.
- Give the form to your practitioner for Part B.This is the medical section. Your practitioner describes how your child's impairment affects daily functioning. They answer specific questions and check boxes about restrictions. This part determines the outcome more than anything else.
- Submit to CRA. You can upload it through CRA My Account online, or mail the paper form. Online is faster.
- Wait for CRA's determination. The official target is 8 weeks. In practice it has been taking up to 15 weeks. If CRA needs more information from your practitioner, it takes longer.
Part B is the control point
Part B asks about specific functional limitations. The practitioner needs to describe how the impairment affects your child, not just confirm the diagnosis. CRA does not approve based on diagnosis. They approve based on the description of daily functional impact. A weak Part B is the most common reason applications are denied.
What do I need to apply for the DTC
Documents and contacts
- CRA Form T2201 (Disability Tax Credit Certificate). Download it from CRA or ask your practitioner for a copy.
- A medical practitioner who knows your child well enough to describe how their impairment affects daily life. This can be a doctor, psychologist, nurse practitioner, occupational therapist, speech language pathologist, physiotherapist, audiologist, or optometrist.
- Your child's medical records in case CRA asks for supporting documentation. They do not always ask, but have them ready.
What happens after your DTC is approved
Approval is a gateway, not a payment. The DTC itself does not put money in your bank account. What changes is that three other things become possible: a monthly Child Disability Benefit (CDB), access to the Registered Disability Savings Plan (RDSP), and a retroactive adjustment of up to ten years of past tax returns, depending on the years CRA approves as eligible. Here is the order it usually plays out.
The approval-to-money sequence
- CRA sends a determination letter. It names the years your child is approved for (can include past years). Keep this letter — you will reference it for every downstream step.
- Claim the DTC on your current tax return. File as usual. The credit applies to the parent claiming the child as a dependant.
- Child Disability Benefit may begin. Child Disability Benefit payments may begin once CRA processes your return, if your family is also eligible for the Canada Child Benefit. CDB is added to the monthly CCB deposit — no separate CDB application is required, but CCB eligibility still applies.
- Request retroactive adjustments. Ask CRA to adjust past returns going back up to ten years, depending on the years CRA approves as eligible. If you qualify, this produces a lump-sum refund plus retroactive CDB.
- Open an RDSP at your bank. Bring the determination letter. The government contributes matching grants (up to $3,500/year) and bonds (up to $1,000/year for lower-income families). Open it early — matching is based on the year you open the account.
You do not need a big tax bill for the DTC to be worth it
The Child Disability Benefit is tax-free, but payment depends on Canada Child Benefit eligibility and family net income. RDSP bonds are specifically for lower-income families. Skipping the DTC because you do not pay much tax is the most common mistake on this page.
What does DTC approval open the door to
DTC approval is required to open an RDSP (government matching up to $3,500/year) and is a prerequisite for Child Disability Benefit (CDB) payments ($3,411/year tax free for the July 2025 to June 2026 period). CDB payments also depend on Canada Child Benefit eligibility. These downstream benefits are the real reason to apply, regardless of your income or tax bill.
Child Disability Benefit (CDB)
Monthly tax free payments from the government. $3,411 per year for the July 2025 to June 2026 period. This amount changes annually. Check CRA for the latest. CDB may be paid if your child is approved for the Disability Tax Credit and your family is eligible for the Canada Child Benefit.
Registered Disability Savings Plan (RDSP)
A savings account for your child's future. The government contributes matching grants up to $3,500 per year and bonds up to $1,000 per year for lower income families. Lifetime cap of $70,000 in grants and $20,000 in bonds. You need DTC approval before you can open an RDSP for your child.
Check CRA for current CDB and RDSP figures. Amounts change periodically.
Your first four steps after DTC approval
- Claim the DTC on your current tax return.
- Ask CRA to adjust your previous tax returns going back up to 10 years, depending on the years CRA approves as eligible. This can result in a lump sum refund.
- Open an RDSP at your bank. Start as early as possible to maximize government matching.
- Child Disability Benefit payments may begin once CRA processes your return, if your family is also eligible for the Canada Child Benefit. CDB is not a separate application from CCB.
Does DTC approval automatically open provincial programs
No. The DTC is federal. It does not automatically register you for Ontario programs like OAP Core Clinical, SSAH, ACSD, or ADP. Each of those has its own application and its own criteria. Having the DTC is useful supporting evidence for some of them, but it is not a substitute for applying.
What the DTC does NOT do
- Does not register you with AccessOAP
- Does not grant SSAH, ACSD, or ADP
- Does not replace a provincial diagnosis report where one is required
- Does not guarantee approval of federal-only streams you may apply to later (for example, CRA benefits that have their own eligibility)
For the full picture of what you should apply to in parallel, see the Start Here guide.
What if my DTC application is denied
A denial is not the end. You have options:
- Submit additional medical information to support the application
- Call CRA at 1-800-959-8281 to discuss the determination
- File a formal objection within 90 days of the determination notice
Many families get approved on the second attempt with better Part B documentation.
What mistakes do families make with the DTC
Does the DTC affect my OAP or SSAH funding
The DTC is a federal CRA program with its own eligibility — it is separate from OAP and SSAH, which are provincial programs decided on their own criteria. Many families hold all three. Do not assume one automatically affects the other; for federal benefit questions confirm with the CRA, and for provincial programs confirm with the relevant program office.
