Can children qualify for the Disability Tax Credit?
Yes. Children qualify under the same categories as adults, but the comparison is against a typical child of the same age. If your child needs far more support, supervision, and time than other children their age for everyday activities, they may qualify. The unused credit transfers to a supporting parent, and approval can connect to other supports.
Parents rarely come to me asking about tax credits. They come exhausted from forms, waitlists, and advocating at school, asking whether there is anything in the system that actually helps. The Disability Tax Credit is one of those things, and children are a major part of who it was built for. Here is how it works for kids, in the plain language I wish someone had handed you at the first appointment.
The comparison that decides children’s claims
Every child needs help. That is not the test. The test is whether your child is markedly more restricted in a basic activity of daily life than a typical child of the same age, and whether that has lasted or is expected to last at least 12 continuous months. Getting dressed, eating, speaking, hearing, moving safely, and the mental functions of everyday life are all assessed against childhood, not adulthood.
For many families this framing is a relief. You are not being asked to prove your child cannot function. You are describing the extra structure your family provides every day: the repeated instructions, the constant supervision, the routines that take three times as long. That is the substance of the application, certified by a medical practitioner on Form T2201.
How the money reaches the family
A child usually owes no tax, so the credit’s value flows through a transfer. The child’s unused disability amount can generally be transferred to a supporting parent or caregiver, reducing the tax that parent owes. Children can also attract a supplement to the credit amount, in recognition of the costs that come with care.
Approval also reaches back. When a child’s approval covers past years, the family can have those tax years adjusted, generally up to 10 years back. Parents are sometimes startled by the size of the accumulated adjustment. It is not a loophole. It is the system acknowledging years the family carried costs alone. I explain how the value is built in how much the DTC is worth.
The two doors approval opens for a child
The first door is the child disability benefit, a tax free monthly payment for families caring for a child under 18 who is approved for the DTC. At the full amount it is worth about $3,300 a year per eligible child, paid together with the Canada child benefit, and back payments can follow a backdated approval. My guide to the child disability benefit covers it in full.
The second door is bigger and slower: the RDSP. A child with DTC approval can have an RDSP opened for them, and inside it, federal grants and bonds can reach $90,000 over their lifetime. Childhood is when that plan has the most years to grow, which is why I urge parents to look at the RDSP early rather than at eighteen. The plan belongs to the child’s future, and time is its best ingredient.
What to do this month
If your child’s daily life involves markedly more support than their peers need, do not talk yourself out of applying because a neighbour’s claim was denied or a forum said your child’s diagnosis “does not count”. Diagnoses do not decide these claims. Effects do. Conditions across the spectrum, from ADHD and autism to hearing loss and learning disabilities, are assessed on daily function, and my condition guides linked from the blog walk through many of them.
Start with the free DTC eligibility checker. It takes about a minute and shows where your child’s situation fits. Then take the T2201 to the practitioner who knows your child’s daily reality best, with your honest examples ready. You are not asking for a favour. You are claiming a support your child was always meant to be considered for.
Common questions
Is there a minimum age for the Disability Tax Credit?
No. Children of any age can be approved if the effects of their impairment meet the test against a typical child of the same age, and the impairment is prolonged.
Who claims a child’s DTC on their taxes?
The child’s unused amount generally transfers to a supporting parent or caregiver, who claims it on their own return. Children can also attract a supplement amount on top of the base credit.
Does a child’s DTC approval help with anything besides taxes?
Yes. Approval connects a family to the child disability benefit, paid with the Canada child benefit, and it is the required approval for opening an RDSP for the child, where grants and bonds can reach $90,000 over a lifetime.
My child’s condition is not listed anywhere. Can they still qualify?
Very likely worth applying. The CRA assesses effects on daily life, not a list of approved diagnoses. If the effects are marked and prolonged compared to other children the same age, the claim can be made.
