If you receive monthly disability payments from the Canada Pension Plan, you also may qualify for tax relief from the Disability Tax Credit. The DTC is a non-refundable tax credit designed to help offset expenses related to having a prolonged physical or mental disability. However, even if you already receive disability payments, you do not automatically qualify for the DTC.
To apply, fill out Part A of Form T2201 and have a qualified medical practitioner fill out Part B of the same form. Send the form to your nearest tax centre. To avoid delays in processing, the Canada Revenue Agency recommends sending in your request for the DTC certificate before submitting your annual tax return.
