[IRS Employee's Claim for Transportation Expenses]

The Internal Revenue Service (IRS) requested a decision regarding an employee's claim for transportation expenses she incurred for personal reasons during travel to and from her temporary duty station. GAO held that: (1) IRS prohibits such reimbursement unless the employee returns to her official duty station; and (2) all employees are chargeable with constructive knowledge of their own department or agency's regulations. Accordingly, the claim was denied.
