The Disability Tax Credit (DTC) is a non-refundable tax credit designed to support Canadians living with severe and prolonged physical or mental impairments. This credit helps reduce the amount of income tax you may owe, making a significant difference for eligible individuals and their supporting family members.
Whether you’re applying for the first time or trying to understand how much you may receive, this guide outlines everything you need to know—including eligibility, calculation methods, and steps to claim the credit effectively.
What Is the Disability Tax Credit?
The Disability Tax Credit is offered by the Canada Revenue Agency (CRA) to offset the additional living costs incurred by people with disabilities. If approved, the DTC allows you to claim a specific amount on your annual tax return. The amount can also be transferred to a supporting family member if the person with the disability does not have enough taxable income to benefit fully.
As of 2025, the federal base amount of the DTC is approximately $9,428. In addition, each province provides a supplemental amount. For Ontario residents, the provincial portion is approximately $8,870. This results in a combined potential tax reduction of over $2,600 annually, depending on your income and tax bracket.
Step-by-Step: How to Calculate the Disability Tax Credit
Step 1: Determine Eligibility
To qualify, you must have a disability that is severe, prolonged (lasting at least 12 months), and certified by a medical practitioner. The condition must markedly restrict your ability to perform basic activities of daily living.
Step 2: Submit the Form T2201
You or your medical practitioner must complete the Disability Tax Credit Certificate (Form T2201) and submit it to the CRA for approval. Processing times may vary, but you can typically expect a response within 8 to 12 weeks.
Step 3: Use the Approved Credit
Once approved, the DTC can be retroactively applied for up to 10 previous tax years if you were eligible during that period. The credit reduces the amount of tax you owe, not the income itself.
Step 4: Calculate Your Benefit
If you qualify for the full credit, you multiply the federal amount ($9,428) by the lowest federal tax rate (15%) and the provincial amount ($8,870) by Ontario’s lowest tax rate (5.05%). That equals a combined tax savings of approximately $2,000 to $2,600 annually.
Step 5: Consider Transfer Options
If you don’t have enough taxable income to benefit from the credit, you may transfer it to a spouse, parent, or other supporting relative. The person claiming the transferred amount must have provided basic care or financial support.
Retroactive Claims and Refunds
One of the major advantages of the DTC is the potential to claim it retroactively. If your condition existed in prior years, and you were eligible but hadn’t applied, the CRA allows retroactive tax adjustments for up to 10 years. In many cases, families receive thousands of dollars in refunds after a successful retroactive claim. This is where working with a tax expert in Ontario can provide real value, as they can identify missed opportunities and ensure accuracy during reassessments.
Common Mistakes to Avoid
Many individuals either delay their application or submit incomplete medical forms, resulting in denial. It’s also common to underestimate the complexity of transferring credits to family members. For these reasons, consulting a tax consultant with experience handling Disability Tax Credit applications can help streamline the process.
