DoD published administrative updates to their Guidebook for Miscellaneous Payments. This update replaces the Standard Form (SF) 1164, Claim for Reimbursement for Expenditures on Official Business, which is obsolete and inactive effective October 2016, with the Optional Form (OF) 1164, Claim for Reimbursement for Expenditures on Official Business. There are no noticeable differences between the forms. Note, the DFAS website states effective February 1, 2017 all reimbursement claims must be submitted using the new OF 1164.
The OF 1164 is available on the General Services Administration website.
Adhering to this guidance will help avoid your designated payment offices returning any miscellaneous payment requests because of using of an obsolete form. If you have any questions, please forward all inquiries to the DFAS Accounting Policy mailbox:
