Sorry---you cannot get the AOTC for graduate school. You can only get that credit for your undergraduate years. For graduate school you can try getting the Lifetime Learning Credit. The LLC is NON-refundable---so it can reduce your tax owed. If you have no tax liability the credit does not do anything.
