My wife and I feed our daughter's High School Marching Band and winter Drum Line which is actually not part of the school but rather a 501c3. We put in a considerable about of time shopping for food, preparing food, serving food & cleaning up. We've done it for four years but recently a co-working said I could have been deducting the expense (mileage for shopping, etc. and any non reimbursed expenses) Is this true? If yes, is it just base on logging mileage and producing receipts for any expenses? Do I need anything from the organization saying we were the "Food Parents". Thank you
