What is an Enrolled Agent?


An Enrolled Agent (EA) is a federally-authorized tax practitioner who has technical expertise in the field of taxation and is empowered by the United States Department of the Treasury to represent taxpayers before all administrative levels of the Internal Revenue Service for audits, collections, and appeals.

What does the term "Enrolled Agent" mean?


“Enrolled”means to be licensed to practice by the federal government, and “Agent” means authorized to appear in the place of the taxpayer at the IRS. Only enrolled agents, attorneys, and CPAs 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 represented citizens in their dealings with the U.S. Treasury Department.

How can an Enrolled Agent help me?


Enrolled Agents advise, represent, and prepare tax returns for individuals, partnerships, corporations, estates, trusts, and any entities with tax-reporting requirements. An Enrolled Agents’ expertise, in the continually changing field of taxation, enables them to effectively represent taxpayers audited by the IRS.


Privilege and the Enrolled Agent


The IRS Restructuring and Reform Act of 1998 allow federally authorized practitioners (those bound by the Department of Treasury’s Circular 230 regulations) a limited client privilege. This privilege allows confidentiality between the taxpayer and the Enrolled Agent under certain conditions. The privilege applies to situations in which the taxpayer is represented in cases involving audit and collection matters. This privilege is not applicable to the preparation and filing of a tax return. This privilege does not apply to state tax matters, although a number of states have an accountant-client privilege.

What are the differences between Enrolled Agents and other representatives? 
Only Enrolled Agents are required to demonstrate to the IRS their competence in matters of taxation before they may represent a taxpayer before the IRS. Unlike attorneys and CPAs, who may or may not choosen to specialize in taxes, all Enrolled Agents specialize in taxation. Enrolled Agents are the only taxpayer representatives who receive their right to practice from the U.S. government (CPAs and attorneys are licensed by the states).

Are Enrolled Agents bound by any ethical standards?


Enrolled Agents are required to abide by the provisions of the Department of Treasury’s Circular 230, which provides the regulations governing the practice of Enrolled Agents before the IRS. National Association of Enrolled Agent members are also bound by a Code of Ethics and Rules of Professional Conduct of the Association.


How to verify someone is an Enrolled Agent?


For verification of an enrolled agent’s status, an individual may ask the enrolled agent to show his or her enrollment card. The card indicates the expiration date for the enrollment license. The date will be shown as 3/31/(year of expiration). An individual seeking to confirm someone’s enrollment can contact the Detroit Office of Practitioner Enrollment at (313) 234-1280 (not a toll-free number) or by email at
When making a verification inquiry, the caller must provide the full name (including middle name or initial if known), and city and state of the Enrolled Agent. The caller will receive verification whether the individual is an Enrolled Agent, the agent’s enrollment number and whether the agent is currently in active status. If the Enrolled Agent’s status is other than “active”, the caller will also get information on whether the status category is: inactive enrollment, inactive retirement, terminated, suspended, or disbarred - and the date such status became effective.
