When are trip expense reports / reimbursement requests due?

Per UC policy, expense reports must be submitted within 45 days after the end of the trip. When a trip lasts more than 90 days, a quarterly report is required. Payments of reimbursement requests submitted after 45 days may be reported as taxable income or may not be paid at all, considering the circumstances and funding sources. A trip expense report must be submitted even if no reimbursement is due the traveler (i.e., when the only expense is direct billed airfare).
