Is any of my father's the home care services tax deductible?

This type of question would be best answered by a CPA or someone who prepares income taxes.   They are up-to-the-minute with updates.

I am trying to think back to 2015 when my Dad had caregivers in his home.   I believe Dad's CPA was able to deduct those amounts, but that for the 2016 filing of 2015 costs.   What was deducted in 2015 may or may not be deducted in tax year 2016.
