Enrolled Agents (EAs) are federally-licensed tax practitioners who may represent taxpayers before the IRS when it comes to collections, audits, and appeals. As authorized by the Department of Treasury's Circular 230 regulations, EAs are granted unlimited practice rights to represent taxpayers before IRS and are authorized to advise, represent, and prepare tax returns for individuals, partnerships, corporations, estates, trusts, and any entity with tax-reporting requirements. Enrolled agents are the only federally-licensed tax practitioners who specialize in taxation and have unlimited rights to represent taxpayers before the IRS. The enrolled agent profession dates back to 1884 when, after questionable claims had been presented for Civil War losses, Congress acted to regulate persons who represent citizens on dealings with the U.S. Treasury Department. Enrolled agents' expertise in the continually changing field of taxation enables them to effectively represent taxpayers at all administrative levels within the IRS.
