What document is filed to claim reimbursement after official travel ends?

The document filed to claim reimbursement after official travel ends is the voucher. A voucher is specifically designed to detail the expenses incurred during the trip and serves as a formal request for reimbursement. It typically includes receipts, data about travel dates, locations, and the nature of the expenses.

On the other hand, an authorization is usually a document that approves and outlines details about the travel before it occurs, including budget estimates. A travel request is submitted prior to the trip to seek permission or funding for travel but does not cover the reimbursement process itself. An expense report, while similar to a voucher and sometimes used interchangeably, typically refers to any report submitted regarding expenses, but specifically, a voucher implies a request for reimbursement following travel completion. Therefore, utilizing a voucher is the recognized process for claiming reimbursement efficiently.
