Large Print-on-Screen Devices
Large print-on-screen devices exclusively designed to enable a patient who is blind to operate a computer, prescribed by a medical practitioner
Are large print-on-screen devices CRA eligible in Canada?
Yes, with a prescription. Large print-on-screen devices are eligible medical expenses under the CRA's Medical Expense Tax Credit (METC). The CRA explicitly includes devices exclusively designed to enable a patient who is blind to operate a computer — including large print-on-screen devices — under paragraph 5700(o) of the Income Tax Regulations, as described in Income Tax Folio S1-F1-C1, paragraph 1.122(s). A prescription from a medical practitioner is required. Because these expenses are METC eligible, they can also be reimbursed through an HSA or PHSP.
What Qualifies

- Rental charges for a qualifying large print-on-screen device
- Reasonable servicing and repair costs for a qualifying device (per Folio S1-F1-C1, paragraph 1.121)
