Among the supports the Canada Revenue Agency administers for parents, one of the least understood is the Child Disability Benefit. It is a tax-free monthly payment for families caring for a child with a severe and prolonged impairment, and because it is delivered automatically to those who qualify, some eligible families may not realise the extra money is tied to steps they still need to complete. For the current benefit year, the CDB can add up to $290.00 per month, or $3,480 per year, for each eligible child.

What the Child Disability Benefit Is

The Child Disability Benefit is a supplement paid on top of the Canada Child Benefit. It is designed to help with the added costs families face when raising a child who has a severe and prolonged physical or mental impairment. Like the CCB itself, the CDB is tax-free and paid monthly rather than as a lump sum. For the July 2026 to June 2027 benefit year, the maximum is $290.00 per month per eligible child, which works out to $3,480 per year. This is a maximum figure, not a guaranteed amount, and the actual payment depends on your family's circumstances.

Who Qualifies

Eligibility for the Child Disability Benefit rests on two conditions being met at the same time. First, the family must be eligible for the Canada Child Benefit for the child. Second, the child must be approved for the Disability Tax Credit, the CRA's non-refundable Credit for people with a severe and prolonged impairment. The Disability Tax Credit is the gateway here. To have a child approved, a medical practitioner must certify the Impairment on Form T2201, the Disability Tax Credit Certificate, which is then submitted to the CRA for review. Only once the DTC is approved for a child under 18, and the family already receives the CCB, does the Child Disability Benefit come into play.

Why It Is Automatic

One of the most important things to understand about the CDB is that there is no separate application for the benefit itself. If you already receive the Canada Child Benefit for a child who has been approved for the Disability Tax Credit, the CRA adds the Child Disability Benefit to your payments automatically. This is where families can miss out. If a child would qualify for the DTC but has never been certified through Form T2201, the CRA has no way of knowing, and the CDB will not be paid. The practical step for many families is therefore to pursue DTC approval; the benefit follows from there.

How the Amount Is Determined

The Child Disability Benefit is income-tested. The full amount is available to families below a certain income level, and it is reduced as adjusted family Net Income rises above the applicable threshold. Higher-income families may receive a partial amount or, depending on their income, none at all. Because the CDB is linked to the Canada Child Benefit, the same filing rules apply. Both you and your spouse or common-law partner must file a tax return every year, even if one of you had no income, so the CRA can recalculate your entitlement for each benefit year.

Conclusion

The Child Disability Benefit can provide up to $290.00 per month per eligible child for the 2026–27 benefit year, and it arrives automatically once a family both receives the Canada Child Benefit and has the child approved for the Disability Tax Credit. Amounts depend on adjusted family net income and are reduced above the threshold. For families who suspect their child may qualify, the key move is securing DTC approval through Form T2201 and keeping tax filings current.
