Can I deduct college tuition I paid on my adult daughter a student loan ? She is 44 and doesn’t live with me?

You cannot deduct any type of education expense on your tax return since the student is not your dependent.

Sorry--no.   That was a gift to her and gifts to individuals are not deductible.

Q. Can I deduct college tuition I paid for my adult daughter?

A. No, unless she is your dependent (unlikely).

But, she can claim it, on her tax return, even though you paid it. The usual rule in taxes is that she must have paid it to claim it, but there is an exception for education expenses. 

Q. Can I deduct college tuition for money I loaned my daughter for school?

A. No, but she can.

There is not an actual deduction. Instead, the student claims a tax credit, calculated on the amount of tuition paid.
