DFAS Fax Number — Retired Pay, Military Pay, and Form Submissions

The Defense Finance and Accounting Service processes pay for military members, retirees, annuitants, and civilian employees through separate pay systems, so the fax destination depends on which DFAS service handles your account. Retired-pay forms, Survivor Benefit Plan paperwork, allotment changes, and garnishment documents each have their own submission instructions. The reliable approach is to open the DFAS page for your specific pay service or the instructions printed on the DFAS form you are completing, which state the accepted contact channels. Because DFAS increasingly uses the myPay portal and secure upload tools, confirm whether fax is accepted for your document before sending.

What You Can Fax to Defense Finance and Accounting Service (DFAS)

  • Retired-pay and annuitant forms requested by DFAS
  • Survivor Benefit Plan election and update documents
  • Direct-deposit and allotment change forms
  • Tax withholding forms such as a W-4 update for pay
  • Garnishment or legal-order documents directed to DFAS
Tip: Confirm the fax destination on the specific DFAS pay-service page or the instructions on the form itself before sending, since each pay system routes to a different office. Do not assume fax is the only channel — many DFAS transactions are handled through myPay or secure document upload — so check the accepted method for your form first. Because these documents include Social Security numbers and financial details, use a secure service and keep the transmission receipt as proof of when and where you submitted.

Faxing to Defense Finance and Accounting Service (DFAS) — FAQ

No. DFAS runs separate pay systems for retirees, active-duty members, annuitants, and civilians, and each publishes its own submission instructions. Match your document to the correct pay service on the DFAS website and use the fax destination that service specifies.

Survivor Benefit Plan elections and updates go to the DFAS retired-pay office using the instructions on the specific SBP form. Confirm the accepted channel and destination in those instructions, include the retiree's identifying information, and retain proof of transmission.

Many pay changes, such as direct deposit, tax withholding, and allotments, can be made in the myPay portal, which is often faster than faxing a form. Check whether your transaction is available in myPay before faxing, and use fax only when the form instructions direct you to.

Garnishment and legal-process documents are handled by the DFAS office that manages legal orders, which publishes specific submission instructions. Follow those instructions for the correct destination and channel, and keep your transmission receipt as a record of service.
