Caregivers: You May Be Entitled to the Disability Tax Credit
One of the most significant and least-known provisions of the Disability Tax Credit is the ability to transfer unused credits to a supporting family member. If you care for a spouse, parent, child, sibling, or other relative who has a qualifying disability — and that person does not have enough taxable income to use the credit themselves — you may be entitled to claim the DTC on your own tax return.
This provision exists because the DTC is a non-refundable tax credit: it reduces the amount of income tax owed, but it cannot generate a refund beyond what was paid. A person with little or no taxable income — such as someone who is unable to work due to their disability — has no tax owing to reduce, so the credit effectively goes to waste unless it is transferred to someone who does have taxable income.
Who Qualifies as a Supporting Person?
The CRA defines a supporting person as someone who, at any time in the year, supports the person with the disability and is one of the following: a spouse or common-law partner, a parent, grandparent, child, grandchild, brother, sister, aunt, uncle, niece, or nephew. You do not need to live with the person you support — you simply need to have provided financial or personal support during the year.
You do not need to be the primary caregiver to qualify as a supporting person. Contributing to the person's care — financially or practically — is sufficient. If multiple family members provide support, the unused DTC can be shared among them.
How the Transfer Works
The transfer is initiated on the T2201 form. In Part A, the applicant (or their representative) indicates that the credit should be transferred to a supporting person and provides that person's name and Social Insurance Number. Once the DTC is approved, the supporting person claims the transferred amount on Line 31800 of their own tax return.
The amount that can be transferred is the portion of the DTC that the person with the disability cannot use — that is, the amount that exceeds their own federal tax owing. If the person with the disability has no taxable income at all, the full credit is available for transfer.
The 10-Year Retroactive Window
The retroactive provision is where the financial impact becomes most significant. If the person with the disability has been eligible for the DTC for prior years — and the credit was never claimed or transferred — you can file T1 adjustment requests to recover those credits going back up to 10 years. For a supporting person in a moderate tax bracket, this can result in a one-time retroactive refund of $10,000 to $25,000 or more.
Every year that passes without claiming the DTC is potentially a year of credits that can no longer be recovered. The 10-year window is fixed — it does not extend backward from the date of diagnosis, but from the date of the adjustment request. Acting sooner rather than later maximizes the retroactive entitlement.
Common Scenarios Where the Transfer Applies
- A spouse caring for a partner with MS, Parkinson's, or severe chronic pain who is no longer able to work
- An adult child supporting an aging parent with dementia or Alzheimer's disease
- A parent of an adult child with autism, severe ADHD, or a developmental disability
- A sibling or other relative providing financial support to someone with a severe mental health condition
What If the Person with the Disability Has Some Taxable Income?
The transfer is not all-or-nothing. If the person with the disability has some taxable income but not enough to use the full DTC, the unused portion — the amount that exceeds their federal tax owing — can be transferred to a supporting person. The person with the disability claims what they can use, and the remainder is available for transfer.
