The Defense Finance and Accounting Service (DFAS) is an agency of the United States Department of Defense (DOD), headquartered in Indianapolis, Indiana. DFAS was established in 1991 under the authority, direction, and control of the Under Secretary of Defense (Comptroller)/Chief Financial Officer to strengthen and reduce costs of financial management and operations within DOD. DFAS is responsible for all payments to servicemembers, employees, vendors, and contractors. It provides business intelligence and finance and accounting information to DOD decisionmakers. DFAS is also responsible for preparing annual financial statements and the consolidation, standardization, and modernization of finance and accounting requirements, functions, processes, operations, and systems for DOD. One of the most visible responsibilities of DFAS is handling military pay. DFAS pays all DoD military and civilian personnel, retirees and annuitants, as well as major DoD contractors and vendors. DFAS also supports customers outside the DoD in support of electronic government initiatives. Customers include the Executive Office of the President, Department of Energy, Department of Veterans Affairs, Department of Health & Human Services, Department of State, U.S. Agency for Global Media and Foreign partners. DFAS is a working capital fund agency financed by reimbursement of operating costs from its governmental customers (mostly the military service departments) rather than through direct appropriations.
