Travel expenses refer to the costs incurred while traveling for business or personal purposes. These expenses can include transportation fees, such as airfare or gas, accommodation costs like hotel stays, and daily allowances for meals and incidentals. Proper documentation of these expenses is essential for reimbursement or tax deductions. When planning a trip, it's important to budget for travel expenses to avoid overspending. Many companies have policies in place to manage these costs, often requiring employees to submit receipts for expenses related to business travel. Understanding what qualifies as a travel expense can help individuals and organizations maintain financial control.
