(*) Enrolled agents (EAs) are only federally licensed tax practitioners who specialize in taxation and also have unlimited rights to represent taxpayers before the IRS. Only enrolled agents are required to demonstrate to the IRS their competence in all areas of taxation, representation and ethics before they are given unlimited representation rights before IRS. Unlike attorneys and CPAs, who are state licensed and who may or may not choose to specialize in taxes, all enrolled agents specialize in taxation.
