Why a
tax attorney.

The structural differences between a tax attorney, a CPA, an Enrolled Agent, and a non-attorney tax practitioner — and why those differences matter when real money, real deadlines, or real exposure are on the line.

Four practitioner categories,
four different authorities.

Federal tax representation is governed by a narrow statutory framework. Only a limited set of practitioners can represent taxpayers before the IRS at all, and within that set, the specific authorities differ materially. Understanding the distinctions matters because most taxpayers hire representation without knowing what the practitioner can and cannot actually do on their behalf.

Attorneys

Licensed by a state bar, bound by state disciplinary rules. Full authority to represent taxpayers before the IRS in all administrative matters. Admitted on motion to practice before the United States Tax Court. Full attorney-client privilege applies to communications about legal advice. Authorized to represent clients in federal criminal tax matters. Trained in federal rules of evidence, Tax Court rules of procedure, and the interpretation of statutes, regulations, and case law.

Certified Public Accountants (CPAs)

Licensed by a state board of accountancy. Authorized under Circular 230 to represent taxpayers in administrative IRS matters. Cannot represent taxpayers in Tax Court without separate admission by passing the Tax Court's non-attorney examination. Limited practitioner-client privilege under IRC §7525 for noncriminal tax advice — a materially narrower protection than attorney-client privilege. Not authorized to represent clients in federal criminal tax proceedings.

Enrolled Agents (EAs)

Federally licensed by the IRS. Authorized under Circular 230 to represent taxpayers in administrative IRS matters. Same Tax Court rule as CPAs: no admission without the non-attorney examination. Same §7525 limited privilege scope. Not authorized in criminal tax matters.

Non-attorney tax practitioners

"Tax resolution specialist," "senior case analyst," "IRS settlement officer," "enrolled representative" — these are marketing titles, not Circular 230 credentials. A person who is not an attorney, CPA, or EA is not authorized to represent any taxpayer before the IRS. At national tax-relief firms, the individual on the phone is often in this category. Cases at these firms are typically handled administratively by a small number of credentialed staff working behind the front-line intake.

The critical distinction

What only a tax attorney can do.

Every adult can file their own Tax Court petition pro se. Credentialed representatives (attorneys, CPAs, EAs) can appear in IRS administrative matters. But four specific authorities belong only to attorneys — and they are the authorities that matter most when the facts are hardest.

One. Attorney-client privilege.

Communications with a licensed attorney about legal advice are protected by attorney-client privilege — a common-law protection that generally cannot be overcome by IRS subpoena or investigative request. Communications with a CPA or Enrolled Agent are protected only by the narrower statutory privilege under IRC §7525. That statutory privilege applies only to noncriminal tax matters, does not apply in most state proceedings, does not extend to communications in furtherance of a tax shelter, and evaporates if the matter becomes criminal. For any client whose situation could conceivably implicate criminal exposure — unfiled returns, significant unreported income, employment tax issues, offshore account questions — the distinction is not academic.

Two. Criminal tax defense.

Criminal tax prosecutions require defense by a licensed attorney. A CPA or EA cannot represent a client in federal criminal tax proceedings — and more importantly, cannot assert privilege over communications once a matter crosses into criminal investigation. The right time to have an attorney involved is before the matter becomes criminal, not after. By the time an IRS Criminal Investigation Division special agent makes contact, the privilege window has often closed.

Three. Tax Court litigation rules.

Attorneys are trained in federal rules of evidence, Tax Court rules of procedure, and the interpretation of precedent. Non-attorney practitioners admitted to Tax Court via the non-attorney examination have passed a rigorous test of procedural knowledge — but they are not trained in law as a discipline. They cannot provide legal advice, even after admission. Their practice in Tax Court is structurally limited to civil tax disputes and to procedural matters within their competence. Cases that turn on statutory interpretation, constitutional argument, or novel application of precedent require an attorney.

Four. Legal interpretation.

The IRS's position on any given matter is the agency's reading of the Internal Revenue Code, Treasury Regulations, Revenue Rulings, and applicable case law. Reversing that position — in Appeals, at Tax Court, or in court filings — requires arguing from the same source material back toward a different interpretation. This is the core work of a lawyer: reading authorities, identifying ambiguity, marshaling argument, and building a record that supports a different conclusion. Non-attorneys are not trained in this work and cannot perform it.

What this means in practice.

For routine IRS administrative matters — simple installment agreements, straightforward penalty abatements, unfiled-return catch-ups on small balances — a capable CPA or EA can handle the work at appropriate cost. The distinction matters less for these cases because the facts are not in dispute, the statute is not ambiguous, and the outcome turns on arithmetic more than argument.

For matters where the facts are contested, the law is unsettled, the exposure is significant, the criminal implications are not zero, or the resolution requires Tax Court, attorney representation is the right level of care. Not because other practitioners are deficient — but because the authorities structurally available to an attorney match the complexity of what those matters require.

The pro se question

Yes, you can petition Tax Court yourself.

Any taxpayer has the right to file a Tax Court petition pro se — to represent themselves without counsel. Approximately 70% of Tax Court petitioners proceed without representation.

The outcome data is also clear: represented parties prevail at materially higher rates than pro se parties. The distinction is not whether you are permitted to proceed alone. It is whether the matter is one where proceeding alone protects your interests. A consultation determines that; a sales call does not.

Request consultation

Frequently asked questions.

My CPA says they can represent me in Tax Court. Is that right?

Only if your CPA has separately been admitted to practice before the Tax Court via the non-attorney examination. CPA licensure alone does not confer Tax Court admission. The Tax Court bar is a separate credential with a separate application process and a difficult written exam. A small number of CPAs and EAs are admitted this way; most are not. If it matters to you, the Tax Court's admissions office can verify admission status.

Does attorney-client privilege apply to my CPA?

No. The limited statutory privilege under IRC §7525 applies to CPAs and EAs for noncriminal federal tax advice. It does not apply if the matter becomes criminal, does not apply in most state proceedings, and does not apply to communications related to tax shelters. Full attorney-client privilege, by contrast, applies to all legal advice from a licensed attorney and is generally not lost when matters shift from civil to criminal.

Can the person at the national tax-relief firm actually represent me?

Only if that person is an attorney, CPA, or Enrolled Agent personally holding a CAF number. At most national tax-relief firms, the individual who signs you up (and often the "case manager" who communicates with you afterward) is not credentialed. The actual IRS-facing work is done by a small number of credentialed staff you typically never speak with directly. Whether this matters depends on whether the representation ever encounters a situation where judgment needs to be exercised in real time.

When does it genuinely not matter which category of representative I hire?

For a straightforward installment agreement on a non-complex balance with no enforcement pending, a competent Enrolled Agent at a modest fee may produce exactly the same outcome as an attorney at a higher fee. The category distinctions matter most when something about the facts could go wrong: criminal implications, contested issues, unfiled returns, active enforcement, Appeals posture, or any situation where Tax Court is a realistic path. In those cases, the cheaper representative is not the more economical choice.
