How to claim for a dependant

If your dependant was 17 or younger

The parent or guardian approved on the DTC application form may claim the disability amount for their child.

To claim for a dependant who was 17 years or younger at the end of the year:

1. Fill out the chart for line 31600 on your Worksheet for the return in the income tax package to calculate the supplement for children with disabilities that your dependant may be able to claim
2. Fill out the chart for line 31800 on your Worksheet for the return in the income tax package to calculate your claim for each dependant

If you pay child support: You cannot claim the disability amount transferred from a child for whom you had to pay child support. However, special rules may apply if you were separated from your spouse or common-law partner for only part of 2022 due to a breakdown in your relationship.

If your dependant was 18 or older

To claim for a dependant who was 18 years or older at the end of the year, fill out the chart for line 31800 on the Worksheet for the return in the income tax package to calculate your claim for each dependant.

Exceptions to claiming

You cannot claim the unused part of the disability amount if your dependant's spouse or common-law partner is:

• claiming the disability amount for your dependant already
• claiming any other non-refundable tax credit (other than medical expenses) for your dependant

If you or anyone else paid for attendant care, or for care in a facility, special rules may apply.
