Message from the DFAS ESS Tax Office – COVID-19 

The ESS Tax Office remains operational, but we ask during this time you refrain from mailing correspondence.  Instead, the preferred way to correspond with the tax office is via email at dfas.cco-1099@maill.mil.  If you have documents these can be scanned and attached to the email correspondence. Emailing is the quickest and most efficient way to submit your documentation at this time.
