Sensory & Communication Impairments
Hearing & Vision Impairments Disability Tax Credit Guide
Guide to DTC eligibility for severe hearing loss, speech discrimination barriers, and visual impairments.
CRA Rules
CRA Hearing & Vision Criteria
How the Canada Revenue Agency (CRA) (the federal office that handles taxes and benefits) reviews who may qualify under Section 118.3 of the Income Tax Act.
Hearing impairments qualify when speech discrimination is restricted 90% of the time even with hearing aids. Vision impairments qualify when visual acuity is 20/200 or less in both eyes after correction, or visual field is restricted to 20 degrees or less.
CRA staff do not approve DTC forms based on diagnosis names alone. They look for clear notes showing that daily-life limits are severe and lasting (at least 12 months in a row).
Main Rules to Meet
- Hearing: Takes three times as long or unable to understand spoken conversation in a quiet setting even with hearing aids.
- Vision: Visual acuity 20/200 or less in both eyes after best correction OR visual field 20 degrees or less.
- Must be certified by an Audiologist (for hearing) or Ophthalmologist/Optometrist (for vision).
- Condition must be severe and prolonged (12+ consecutive months).

Avoiding a No
Why Hearing & Vision Impairments claims get denied
Common mistakes doctors and applicants make on Form T2201 Part B (the medical part).
Failing to Conduct Speech Discrimination Testing
Submitting standard audiograms without speech recognition in noise or quiet testing.
Assuming Wearing Hearing Aids Excludes You
If speech comprehension remains restricted even WITH hearing aids, you can still qualify.
Not Involving an Audiologist or Ophthalmologist
CRA requires specific sensory specialists for hearing and vision certification.
Quick Self-Check
If 2 or more of these fit your life, applying for the DTC may be worth a look:
- ☑Even with hearing aids, do you struggle to understand conversation in a quiet room 90% of the time?
- ☑Do you rely on lip-reading, written notes, or Sign Language for basic daily communication?
- ☑Is your visual field restricted to 20 degrees or visual acuity 20/200 or less after glasses?
- ☑Has sensory impairment persisted for at least 12 months?
