Keep all itemized receipts and proof of payment. For any expense over $75.00, in addition to the receipt, you will also need to include the proof of payment. If the receipt shows the last four digits of the credit card charged that is adequate as proof of payment. If the receipt does not contain that information, you will need to submit either a cancelled check or the credit/bank card statement reflecting the payment made.
For meals expenses incurred during your trip, please write on the receipt the type of meal, i.e. breakfast, lunch, dinner as we are required to categorize in this way when entering the expenses for reimbursement. All small receipts of this type should be taped to 8 ½ x 11 paper in chronological order.
