IRS Circular 230: What It Means When You Hire a Tax Professional
IRS Problems · TAXPAYER RIGHTS
Circular 230 sets the ethical and professional standards for anyone who represents taxpayers before the IRS — including enrolled agents. Here's what it requires and how it protects you.
When you hire an enrolled agent, CPA, or tax attorney to help with your taxes or represent you before the IRS, that professional is bound by a federal rulebook called Circular 230. Published by the Treasury Department, it governs how tax professionals must conduct themselves — what they can advise, how they must respond to IRS requests, and what happens when they step out of line. Understanding it helps you choose a qualified professional and know your rights.
What Is Circular 230?
Circular 230 (formally titled 'Regulations Governing Practice before the Internal Revenue Service') is a set of Treasury Department regulations that apply to anyone who 'practices before the IRS.' This includes enrolled agents (EAs), attorneys, certified public accountants (CPAs), enrolled actuaries, and other authorized practitioners.
Circular 230 covers:
• Who can represent taxpayers before the IRS
• What information practitioners must provide to clients and the IRS
• Standards for tax opinions and written advice
• Conflicts of interest and confidentiality rules
• Disciplinary procedures and sanctions
Who Can Practice Before the IRS?
Not everyone can represent you before the IRS. Circular 230 authorizes:
• Enrolled Agents (EAs) — licensed by the IRS after passing a rigorous three-part examination. Unlimited representation rights.
• Attorneys — licensed by their state bar
• Certified Public Accountants — licensed by their state board
• Enrolled Actuaries — limited to pension matters
• Enrolled Retirement Plan Agents — limited to retirement plan issues
A regular tax preparer who is not one of the above has limited rights — they can only represent you for an audit of a return they prepared, and only in certain circumstances. Unlicensed preparers cannot negotiate with IRS collection or appear before the IRS Appeals Office on your behalf.
What Circular 230 Requires of Your Tax Pro
Key requirements your tax professional must follow:
• Promptly return client records — even if you owe them fees
• Disclose to the IRS any known errors on a prior return if the client won't correct it
• Not knowingly assist in fraudulent returns or provide false information to the IRS
• Not charge 'unconscionable' or contingency fees for most IRS representation matters
• Maintain client confidentiality
• Disclose any conflicts of interest before agreeing to represent you
• Respond to IRS requests for information within a reasonable time
Standards for Written Tax Advice
Circular 230 sets standards for written tax advice (including opinion letters). A practitioner must:
• Base opinions on reasonable assumptions
• Not rely on unreasonable factual representations
• Consider all relevant facts
• Not omit important qualifications
This protects taxpayers from promoters who issue aggressive 'opinion letters' designed to provide legal cover for abusive tax shelters. If a practitioner gives you written advice promising unusually large deductions or 'guaranteed' tax elimination, Circular 230 gives you grounds to question their methodology.
What Happens When a Tax Pro Violates Circular 230?
The IRS Office of Professional Responsibility (OPR) investigates Circular 230 violations. Sanctions range from:
• A written reprimand (censure)
• Suspension from practice before the IRS for a period of time
• Disbarment (permanent prohibition from IRS practice)
Disciplined practitioners are listed in the IRS's public disciplinary database. You can search for any practitioner's disciplinary history at irs.gov. Always verify credentials before hiring — search for enrolled agents in the IRS directory at irs.gov/taxpros.
Frequently Asked Questions
What's the difference between an enrolled agent and a CPA for IRS problems?
Both EAs and CPAs can represent you before the IRS at any level — audits, appeals, collection. Enrolled agents specialize exclusively in tax and are licensed directly by the IRS, making them uniquely focused on IRS representation. CPAs have broader accounting credentials but may or may not specialize in IRS representation. For complex IRS collection or audit issues, an EA with IRS representation experience is often the best choice.
My tax preparer prepared my return but won't help me during an audit. Is that allowed?
If your preparer is not an EA, CPA, or attorney, their representation rights are limited. They can only represent you in an audit of a return they signed, and cannot represent you in appeals or collection matters. This is why working with a credentialed professional who has full Circular 230 representation rights is important.
Can my tax professional refuse to file an amended return if I find an error?
A practitioner cannot file a return they know to be fraudulent or materially incorrect. But if you discover an honest error, your practitioner is required to advise you to correct it. If you refuse, the practitioner must decide whether to continue representing you — they cannot knowingly assist you in maintaining an incorrect position.
How do I verify that an enrolled agent is in good standing?
Search the IRS Return Preparer Directory at irs.gov/taxpros. You can search by name and location and verify that an EA's credential is current and that they have no public disciplinary actions on record.
