Tax Attorney vs CPA: Which One Do You Need?

Last reviewed: October 6, 2026. This article is general information, not legal or tax advice. CPA licensing is set by each state's board of accountancy, so check your state's current requirements.

Tax letters can be stressful, and figuring out who to call shouldn't add to the stress. The good news: tax attorneys and CPAs both help with taxes, and for many everyday tasks either one, or an enrolled agent, is a fine choice. The differences really start to matter when there's a dispute, a lawsuit or a possible criminal issue.

Short answer: In the tax attorney vs CPA question, a CPA is a licensed accountant who prepares returns, keeps books, plans taxes and can represent you before the IRS. A tax attorney is a lawyer who can do much of that too, but can also give legal advice, represent you in court and offer full attorney-client privilege. A CPA's confidentiality protection under federal law is narrower and doesn't apply in criminal matters. For routine returns and audits, a CPA or enrolled agent is usually enough; for criminal exposure or tax litigation, talk to a tax attorney.

Training and licensing

Tax attorneys

A tax attorney is a lawyer: they have a law degree, passed a state bar exam and are licensed by a state (see what does bar stand for in law). "Tax attorney" describes a lawyer's focus rather than a separate license. Some tax lawyers also have an advanced law degree in taxation, and some are also CPAs.

CPAs

A Certified Public Accountant is licensed by a state board of accountancy after passing the Uniform CPA Examination and meeting education and experience requirements. According to NASBA, the national model now recognizes three pathways: the traditional 150 semester hours with one year of experience, a graduate degree in accounting with one year of experience, and a newer route of a bachelor's degree (120 hours) with two years of experience. Each state must adopt these through its own law, so the rules depend on where the CPA is licensed.

Enrolled agents

An enrolled agent (EA) is licensed by the IRS itself. The IRS says EAs must pass a three-part Special Enrollment Examination covering tax planning, return preparation and representation, pass a suitability check, and complete 72 hours of continuing education every three years. EAs are a useful, often less expensive, option for returns, audits and collection problems.

Who can represent you before the IRS

Treasury's rules for tax practice, known as Circular 230, list who may practice before the IRS. Under 31 CFR 10.3, attorneys, CPAs and enrolled agents who are not suspended or disbarred may represent taxpayers. The IRS describes these three as having unlimited representation rights: they can represent clients on any matter, including audits, payment and collection issues, and appeals.

By contrast, a preparer who only has a PTIN (the number every paid preparer needs) generally has no authority to represent clients before the IRS. Participants in the IRS Annual Filing Season Program have limited rights, covering only returns they prepared and only before certain IRS employees.

In the US Tax Court

Going to court is different. Under Tax Court Rule 200, attorneys are admitted to practice on proof that they're members in good standing of a bar. A non-attorney, including a CPA or EA, must pass a written examination given by the court and be sponsored by people already admitted.

Privilege: the biggest legal difference

What you tell your adviser could one day be sought by the IRS or the Department of Justice, so privilege matters.

• Attorney-client privilege protects confidential communications with your lawyer made to get legal advice, in civil and criminal matters alike, subject to recognized exceptions.
• The § 7525 privilege gives similar protection to "federally authorized tax practitioners," such as CPAs and EAs, but only for tax advice and only in noncriminal federal tax matters before the IRS or in federal court. Under § 7525(b), it also doesn't cover certain written communications about promoting participation in tax shelters.

If a civil matter turns into a criminal investigation, communications with your CPA may not be protected. That's why lawyers sometimes hire an accountant to help them advise a client, an approach often called a "Kovel arrangement" after United States v. Kovel (2d Cir. 1961). In that case the court held that an accountant's presence while a client explains a complicated tax story to the lawyer "ought not destroy the privilege." But it also warned: "If what is sought is not legal advice but only accounting service... or if the advice sought is the accountant's rather than the lawyer's, no privilege exists."

When to hire which

A CPA or enrolled agent is usually a good fit for:

• preparing individual and business returns;
• bookkeeping, payroll and financial statements;
• tax planning and estimated payments;
• most routine audits and correspondence with the IRS;
• payment plans and many collection issues.

A tax attorney is usually the better choice for:

• any sign of a criminal tax investigation (for example, contact from IRS Criminal Investigation) or concerns about past returns that might be treated as fraud;
• Tax Court cases and other tax litigation;
• large or complicated disputes, especially where legal interpretation is at issue;
• legal planning such as business structuring, trusts and estates, alongside an accountant.

Many people use both: an accountant for the numbers and an attorney for the legal strategy. If a tax issue might overlap with fraud allegations, our guide to white collar crime attorneys explains how those cases work.

Before you hire anyone

1. Check credentials. Look up attorneys with the state bar, CPAs with the state board of accountancy, and confirm an EA's status with the IRS.
2. Ask about experience with your exact issue, such as audits, collections or Tax Court.
3. Get the fee in writing, including what's included.
4. Be cautious early. If you're worried a matter could become criminal, speak to an attorney before giving detailed explanations to anyone else.
