15 Corporate Travel Policy Miscellaneous Travel policies should contain clear guidelines around implicit travel expenses like tipping, and acceptable incidental expenses, such as laundry or valet services. Guidelines on Tipping The table to the right is an example of a tipping guidelines chart that is helpful to include in your travel policy. The table below is based on general US practices and should be customized to your organization’s policy. You may need more than one table to accommodate regional differences. Ancillary Expenses Covered Many policies provide guidance on a variety of ancillary expenses, such as: • Charitable Donations: the policy should delineate eligibility criteria and exclusions, as well as the request procedure and corporate matching policy. • Professional Development: the policy should indicate who is eligible for reimbursement, which expenses are eligible, what constitutes the request process, and how employees are reimbursed for expenditures. • Technical Business Publication Subscriptions: the policy should delineate when the employer will, and will not, reimburse the costs of subscriptions for technical publications. • Professional Association Membership Dues: the policy should delineate when the employer will, and will not, reimburse the costs of professional association dues.
