Disability Amount Tax Credit
To qualify for this non-refundable tax credit, a form T2201 Disability Tax Credit Certificate must be completed, certified and submitted. This form has sections on various types of physical or mental impairments. Each section asks for the year in which the impairment began. However, in order to have the disability tax credit applied retroactively, a form T1Adj must be filed for each previous tax year in which the person qualifies. See our article on changing your tax return for how to do this, and the time periods for which it can be done.
If part or all of the disability amount tax credit cannot be used by the taxpayer, it can be transferred to a spouse or common law partner, or to a supporting taxpayer (e.g. parent, child). See the Canada Revenue Agency (CRA) information on Line 318 - Disability amount transferred from a dependent.
If a qualified person (usually a medical doctor) certifies that you have a severe and prolonged mental or physical impairment which markedly restricts the ability to perform a basic activity of daily living, then a disability amount may be claimed. For 2005 and later years, eligibility for the disability amount tax credit includes persons with a severe and prolonged mental or physical impairment which significantly restricts the ability to perform more than one basic activity of daily living, including
- speaking
- hearing
- walking
- elimination (bowel or bladder functions)
- feeding
- dressing, or
- performing the mental functions necessary for everyday life
If the cumulative effect of the restrictions in performing activities is equivalent to having a single marked restriction in one activity, then the person will be eligible for the disability tax credit.
The term "markedly restricted" as defined by the Income Tax Act s. 118.4(1)(b):
"an individual's ability to perform a basic activity of daily living is markedly restricted only where all or substantially all of the time, even with therapy and the use of appropriate devices and medication, the individual is blind or is unable (or requires an inordinate amount of time) to perform a basic activity of daily living"
If you are under 18, an additional amount may be claimed. This may be reduced by any child care or attendant care expenses that were claimed by you or a supporting person..
Life-sustaining therapy
Individuals receiving extensive therapy are eligible for the disability tax credit (DTC) if their therapy meets 3 conditions:
- It is essential to sustain a vital function of the individual,
- It is required to be administered at least 3 times each week for a total duration averaging not less than 14 hours a week, and
- It cannot reasonably be expected to be of significant benefit to persons who are not so impaired.
The following changes were made for 2005 and later years, to better define activities that are considered therapy, and will be considered as time spent receiving therapy:
- Where the therapy has been determined to require a regular dosage of medication that needs to be adjusted on a daily basis, the activities directly involved in determining the appropriate dosage will be considered part of the therapy.
- Therapy does not include activities such as following a dietary restriction or regime, exercise, travel time, medical appointments, shopping for medication or recuperation after therapy.
- The time it takes to administer the therapy must be time dedicated to the therapy—that is, the individual has to take time away from normal, everyday activities in order to receive the therapy. Further, in the case of a child who is unable to perform the activities related to the therapy as a result of his or her age, the time spent by the child’s primary caregivers (i.e. parents) performing and supervising these activities for the child can be considered time dedicated to the therapy
With these changes, many children with severe cases of Type I diabetes may be eligible for the DTC.
