I’m a man in my 90s and need 24/7 care. I’ll be paying $2,000 a week for this service. Is it deductible?

If such care is medically necessary, as prescribed and certified by a licensed health care provider, then it can be treated as a deductible medical expense if you itemize deductions. For 2016, only out-of-pocket medical expenses in excess of 7.5% of your adjusted gross income can be deducted. Starting in 2017, the AGI threshold rises to 10% unless Congress changes the law.
