My son uses a joint CC for his groceries and carryout/dining expenses while attending college and staying in his university approved, off-campus apartment. In this manner, I have access to all his room and board expenses, but I'm not sure how good he was about keeping actual paper receipts for online food orders, etc. Can I submit whole grocery & dining expenses, including taxes (and tips) he may have incurred? Or can I not submit taxes and tips as part of the board expense, to reimburse myself from our 529 plan?
