General Guidelines
The Internal Revenue Code provides institutions with requirements that must be met to qualify research and travel expenses as legitimate business deductions. The following guidelines have been established within the framework of these regulations. The regulations require that adequate personal records of each trip be kept, and pertinent information in support of each research or travel expenditure be submitted to your institution. Original receipts are required for all expenses in excess of US $25.00. Reimbursements for expenditures which are not documented by receipts are considered taxable income and must be reported to the Internal Revenue Service. All expenditures should be within the range approved by the U.S General Services Administration.
If you have come to IAS with an individual federal or state grant that is administered by IAS, contact Roxanne Bridger, 
, for expense reimbursement guidelines specific to your grant.

The travel voucher is available in a pdf version [1]. The dates and purpose of travel should be noted clearly on the voucher. A record of expenses incurred by the individual while traveling should be maintained and documented by original receipts. Current exchange rates for foreign denominations can be obtained from the Classic 164 Currency Converter [2].
