I agree with cdnreader above about checking with a tax person or accountant.
My Dad was able to deduct his professional caregivers who were from an Agency because he had a written contract with the Agency, plus he was a fall risk which his CPA said was acceptable.
If the care is prescribed by a doctor and is medically necessary, I would think so. But, check with an accountant or elder law attorney. I hope you have a care agreement. May be one of the prerequisites.
I would check with an H and R Block rep or an accountant about this question.
