Can a self-employed person in Ontario claim the disability tax credit?

TSL Written by the Treadstone Law team· Updated June 2026

Yes. The Disability Tax Credit (DTC) is a federal non-refundable tax credit available to eligible individuals regardless of their employment status. Being self-employed does not disqualify you from claiming the DTC. You must apply by having a qualified practitioner certify that you have a severe and prolonged impairment in physical or mental functions, and the CRA must approve your application.

Once approved, the DTC reduces the amount of federal income tax you owe. There is a corresponding provincial credit in Ontario under the Ontario tax system. The credits are non-refundable — they reduce taxes owed but do not generate a refund if your tax payable is zero. Unused DTC amounts can in some cases be transferred to a supporting spouse, common-law partner, or other supporting person.

Eligibility is based on the nature and duration of the impairment, not on income level or employment status. The application process involves Form T2201, completed by your doctor or other qualified health professional. If you have been denied the DTC and believe you qualify, there is an appeals process. Speaking with a tax professional can help you navigate the application or appeal.

Key takeaways

  • Self-employed individuals are fully eligible for the federal Disability Tax Credit.
  • Eligibility depends on medical certification of a severe and prolonged impairment.
  • The DTC is non-refundable; unused amounts can sometimes be transferred to a supporting person.
  • Apply using Form T2201; denied applications can be appealed.
