"Designed to offset the extra living costs related to having a disability, the disability tax credit is a non-refundable credit used to reduce your taxes owed. In order to qualify, you must have a serious and prolonged physical or mental impairment. Depending on the situation, you may be able to claim this credit for yourself, or on behalf of your dependent, spouse or common-law partner."
