The Miscellaneous Expense Portion of the FTA is to help cover "miscellaneous" expenses incident to a foreign assignment such as pet transportation; vehicle registration; driver's license; utility fees or deposits not offset by an eventual refund; and conversion of appliances. The flat amount for an employee without family is the lesser of either one-week's salary or $650. For an employee with family it is the lesser of two weeks' salary or $1,300. A higher rate is available if the employee provides itemized receipts. See DSSR 242 at the above website for precise calculations.
Note: Transferring employees (those currently working for the U.S. Government) are entitled to the Miscellaneous Expense Allowance under Chapter 5, Part B, of the Joint Travel Regulations, and must use a Travel Voucher or Subvoucher (DD Form 1351-2) to apply for reimbursement.
