§301-11.4. Determining the applicable per diem reimbursement rate.

Generally, the temporary duty (TDY) location determines the per diem reimbursement rate. However, if lodging is obtained outside the TDY location, the agency may authorize or approve the per diem rate for an alternate location if it is advantageous to the government. If arriving at the lodging facility after 12 midnight, an employee may claim the lodging cost for the preceding calendar day.
