Your Situation

Your Disability Tax Credit
Total DTC (federal + provincial)
Annual reduction in the tax you owe (non-refundable)
Federal Credit
$10,341.00 × 14%
Provincial Credit
$10,017.00 × 5.05%
Non-refundable means the credit can reduce your tax to zero but is not paid out as a refund. If the disabled person has little or no tax to pay, the unused credit can be transferred to a supporting spouse or relative.
You must have an approved Form T2201 (Disability Tax Credit Certificate) signed by a medical practitioner. Approval can also open the door to the Registered Disability Savings Plan, the Child Disability Benefit, and the Canada Workers Benefit disability supplement. You can request reassessments up to 10 years back.

This does not model the credit transfer optimisation, the Quebec return in full, or your actual tax payable. Confirm figures on your provincial worksheet or with the CRA, and ensure Form T2201 is approved.

Frequently asked questions
How much is the Disability Tax Credit worth in 2026?
For 2026 the federal disability amount is $10,341, which at the 14% lowest-bracket credit rate is worth $1,447.74 in federal tax savings. Each province adds its own disability credit on top, so the combined DTC is typically worth about $1,800 to $2,200 a year for an adult, depending on where you live.
Is the Disability Tax Credit refundable?
No. The DTC is a non-refundable credit, so it reduces tax owing but is not paid out as a refund. If the person with the disability has little or no tax to pay, the unused credit can be transferred to a supporting spouse, common-law partner, or another supporting relative such as a parent or grandparent.
What is the supplement for children under 18?
A person who is under 18 at year-end qualifies for an additional federal supplement of up to $6,032 for 2026. The supplement is reduced dollar-for-dollar by any child care or attendant care expenses claimed above $3,533, and is fully eliminated once those expenses reach $9,565.
How do I qualify for the Disability Tax Credit?
You need CRA approval of Form T2201, the Disability Tax Credit Certificate, certifying a severe and prolonged impairment in physical or mental functions. A qualified medical practitioner completes part of the form. Once approved, you can ask the CRA to reassess prior returns back up to 10 years.
What other benefits does DTC approval unlock?
DTC approval opens the door to the Registered Disability Savings Plan (RDSP) with government grants and bonds, the Child Disability Benefit added to the Canada Child Benefit, the Canada Workers Benefit disability supplement, and the Canada Disability Benefit.
Why does the credit differ between provinces?
The federal amount is the same everywhere, but each province sets its own disability amount and applies it at its own lowest tax rate, so the provincial portion of the credit varies. Quebec administers its disability credit separately on the Quebec return.
