My spouse is able to claim the Disability Tax Credit for a mental illness.
Can counselling sessions with a social worker be claimed as a medical expense?
If so, do you need a prescription or a note from your doctor? The government documentation says it should be "supervised by a medical professional".
If the counselling is considered “therapy”, then you can claim the expense, if it was prescribed. If there was no prescription, then you probably can’t claim it. You can always double check with the CRA. If you are in Canada or the United States, you can call the Canada Revenue Agency (CRA) at 1-800-959-8281. If you are elsewhere you can call 613-940-8495.
