Q. Can he claim the tuition reported to him on Form 1098-T to claim the Education Tax Credit even though technically I paid it?
A. Yes. Although the general rule, in taxes, is that you must be the one making the payment, to get the deduction or credit, there is an exception for education.
Q. I do not think I can claim as a dependent. However, he had a part time job and earned some income?
A. If his income was over $5050, you cannot claim him. However, if he takes 12 credit hours (full time) for one semester (not quarter, it has to cover parts of 5 months), the dependent rules change.
