304-3.11—Am I limited to the maximum subsistence allowances (per diem, actual expense, or conference lodging) prescribed in applicable travel regulations for travel expenses paid by a non-Feder
Generally yes. Subsistence expenses are usually limited to the maximum subsistence allowances (per diem, actual expenses or conference lodging) prescribed in chapter 301 of this title for travel in CONUS, by the Secretary of Defense for travel in non-foreign areas and by the Secretary of State for travel in foreign areas. However, acceptance of payment for, and when applicable, reimbursement by an agency to an employee and the accompanying spouse of such employee are not subject to the maximum per diem or actual subsistence expense rates when traveling in CONUS or in non-foreign areas under the following conditions:
(a)
The non-Federal source pays the full amount of the subsistence expense, as authorized by your agency; and
(b)
The subsistence expense paid by the non-Federal source is comparable in value to that offered to or purchased by other meeting attendees; and
(c)
Your agency has approved acceptance of payment from the non-Federal source prior to your travel; if your agency has not approved any acceptance from the non-Federal source, you may not exceed the maximum allowances. See § 304-3.13.
