Can I deduct expenses spent on providing for my 19 yr old's living expenses outside of my primary home (rent, utilities, internet, food/ monthly stipend for bills etc

[DawnC]

No.  Those are not tax-deductible expenses.

If he is a full-time student you can claim him as a dependent and get the $500 credit for other dependents.  If he was 19 at the end of 2023 and is not a student and had over $4700 of income you cannot claim him as a dependent.

But you do not ever get to deduct the living expenses you pay for a child or family member.  Sorry.

IRS interview to help determine who can be claimed:
