All tax returns are prepared by an Enrolled Agent. An enrolled agent (EA) is a federally-authorized tax practitioner who has technical expertise in the field of taxation and who is empowered by the U.S. Department of the Treasury to represent taxpayers before all administrative levels—examination, collection, and appeals—of the Internal Revenue Service. In addition to taxpayer representation, enrolled agents often provide tax consultation services and prepare a wide range of federal and state tax returns.
