In regard to the allowable Qualified Education Expense that is payable from a 529 plan - you asked if your meals expense was allowable given that you are a resident student but do not participate in the educational institutions board (meal) plan:
In other words, the maximum allowable expense for the combination of room and board, even if meals are not part of the meal plan, is that amount set by the school if you were using both room and board from the school."Room and Board – If the student is attending college half-time or more and the room and board are paid directly to the college or university this is a qualified expense.
"If room and board are to be paid to a landlord and grocery store, the budget is set by the school and is available to students who are attending half-time or greater. "
