The disability tax credit (DTC) is a non-refundable tax credit that helps people with impairments, or their supporting family member, reduce the amount of income tax they may have to pay.

If you have a severe and prolonged impairment, you may apply for the credit. If you are approved, you may claim the credit at tax time.

By reducing the amount of income tax you may have to pay, the DTC aims to offset some of the extra costs related to the impairment.
