The Key Difference
A tax attorney holds a law license. A CPA holds an accounting license. Those are different things, and they matter most when the government is involved.
The fundamental distinctions are two: legal representation authority and privilege.
Both a CPA and a tax attorney can represent you before the IRS in most circumstances. Both can file a Form 2848 Power of Attorney. But what they can say to you — and what happens to those communications if the IRS or the DOJ comes looking — is governed by entirely different rules.
Attorney-client privilege fully protects communications between you and your tax attorney. It applies in civil proceedings and criminal proceedings alike. A CPA's communications carry no comparable protection in most situations. That distinction is not a technicality. In a matter with any serious exposure, it is the whole game.
What a CPA Can Do
A licensed CPA is the right professional for the financial and compliance side of your tax life.
Under IRS Circular 230, CPAs have unlimited representation rights before the IRS — the same tier as attorneys. A CPA can file Form 2848 to act as your authorized representative, appear in IRS audits, correspond with the IRS on your behalf, and represent you in IRS Appeals in non-docketed cases.
Specifically, a CPA can:
- Prepare and file federal and state tax returns
- Provide tax planning and compliance advice for business transactions
- Represent you in correspondence audits and field examinations
- Represent you in IRS Appeals on unagreed audit issues
- Handle responses to CP2000 notices, 30-day letters, and other IRS correspondence
- Advise on accounting method elections, depreciation, and entity structure from an accounting standpoint
California CPAs are licensed by the California Board of Accountancy under Business & Professions Code § 5000 et seq. That license covers accounting, attest services, and financial reporting — not legal representation in court or criminal proceedings.
There is a third category worth mentioning: the IRS Enrolled Agent (EA). An EA is a federally licensed tax practitioner — not an attorney, not a CPA — with unlimited IRS representation rights under Circular 230. EAs are tested specifically on tax procedure and IRS practice. They can represent you before the IRS in audits, appeals, and collection matters. They are often excellent at that work. What they cannot do is invoke attorney-client privilege, appear in court, or practice law.
What a Tax Attorney Can Do That a CPA Cannot
The three areas where an attorney is categorically different from a CPA are privilege, Tax Court representation, and criminal defense.
Attorney-Client Privilege
Communications between you and your tax attorney are protected by attorney-client privilege in all proceedings — civil and criminal, federal and state. That protection belongs to you, and only you can waive it.
IRC § 7525 creates a limited federally authorized tax practitioner privilege that applies to CPAs and EAs. But that privilege has significant gaps that matter in practice:
- It covers only non-criminal federal tax matters
- It does not apply in criminal investigations or prosecutions
- It does not apply in state proceedings (so no protection in a California FTB or EDD matter)
- Courts have interpreted it narrowly, and there are open questions about when it applies in IRS civil examination versus Appeals
The practical result: if your CPA learns something that the government later finds relevant to a criminal investigation, that conversation may not be protected. If your tax attorney learns the same thing, it is protected.
The Kovel Arrangement
There is a way to bring a CPA's expertise inside the privilege umbrella: a Kovel letter. Under United States v. Kovel, 296 F.2d 918 (2d Cir. 1961), a tax attorney can retain a CPA to provide accounting assistance as part of the attorney's legal work. The CPA's work product is then protected by the attorney-client privilege — the accountant is functioning as the attorney's agent, not as an independent professional.
We use this structure regularly in matters where we need detailed accounting work done alongside an active legal strategy.
U.S. Tax Court
The U.S. Tax Court is an attorney forum. Under Tax Court Rule 200, attorneys who are members in good standing of any state bar are admitted to practice before the Tax Court. CPAs and EAs can apply for Tax Court admission separately, but they are not automatically admitted.
If the IRS issues you a Notice of Deficiency (commonly called a 90-day letter), you have 90 days to petition the Tax Court to contest the assessment before paying the tax. If you want to take that dispute to Tax Court, you need an attorney who is admitted to practice there.
Criminal Tax Defense
Once IRS Criminal Investigation (CI) opens a case, or if a special agent contacts you, you are in a criminal investigation. CPAs cannot represent you in that process. They cannot appear in federal court proceedings, and they cannot negotiate criminal resolutions with the DOJ Tax Division.
If a CI special agent has contacted you — even if described as a "routine" inquiry — call a tax attorney before saying anything further. That is not fear-based advice. It is procedural reality.
Decision Framework: When to Use Each
Here is a practical guide to choosing the right professional based on the type of problem.
Use a CPA When:
- You need your federal or state tax return prepared
- You have bookkeeping or financial reporting questions
- You received a CP2000 notice for underreported income with no fraud indicators
- You are doing routine tax planning for a business transaction
- You are in a straightforward IRS correspondence audit over a specific line item
Use a Tax Attorney When:
- A CI special agent has contacted you or sent you a letter
- You are under a field examination with fraud indicators — cash-intensive business, large unexplained deposits, a prior audit history that raised concerns
- You are disputing a substantial tax liability in IRS Appeals or want to petition the Tax Court
- You have foreign accounts, foreign assets, or foreign business interests with unreported or incorrectly reported obligations
- The IRS has filed a Notice of Federal Tax Lien, issued a levy, or is threatening wage garnishment or asset seizure
- You are evaluating an Offer in Compromise and want the Reasonable Collection Potential (RCP) analysis done correctly before you file
- Your matter involves California FTB, EDD, or CDTFA and may move to the Office of Tax Appeals or the CUIAB
The dividing line is not the size of the tax liability — it is the nature of the dispute and the exposure. A $40,000 audit with fraud indicators is a more serious matter than a $400,000 audit over a clear accounting issue. What the government is looking at, and what they might find, determines who you need on your side.
What About Tax Resolution Companies?
Tax resolution companies are non-attorney, non-CPA businesses that advertise IRS debt relief. For a matter with any complexity, they are generally not the right choice.
These companies typically use enrolled agents or other Circular 230 practitioners. They can file Form 2848 and communicate with the IRS. But they cannot invoke attorney-client privilege, they cannot appear in Tax Court, and they cannot handle a matter that develops criminal implications.
The short answer: for IRS collection matters with real complexity — an Offer in Compromise where the financial analysis matters, a collection due process hearing, a matter with lien or levy complications — a tax attorney is the appropriate professional. For a routine payment plan with no exposure beyond the balance owed, an EA can do that work competently.
The problem with resolution companies specifically is that their business model often involves charging substantial upfront fees while understating the difficulty of the matter. That is not a universal indictment — there are competent practitioners in that space — but it is a pattern worth being aware of.
How I Work With CPAs
The attorney handles the legal dispute. The CPA handles the books and ongoing compliance. Those roles work best when they are coordinated.
I hold a J.D., an LL.M. (Taxation), and an MBA. The LL.M. in Taxation is a post-J.D. graduate degree focused specifically on tax law — federal income tax, corporate tax, partnership tax, international tax, estate and gift tax, and tax procedure. It is the specialized credential for attorneys who practice tax law full time.
In practice, I work alongside clients' existing CPAs and accountants regularly. The division of work is straightforward: I handle the IRS or state agency relationship, the legal strategy, the representation in proceedings, and any privilege analysis. The CPA handles the financial statements, the return preparation, and the compliance work going forward.
For clients who do not have a CPA, I can refer them to trusted accounting professionals in San Diego. Getting the right team assembled early — before the IRS digs in — is usually worth it.

Frequently Asked Questions
Can a CPA represent me in an IRS audit?
Yes. Under IRS Circular 230, a licensed CPA has unlimited representation rights before the IRS and can file a Form 2848 Power of Attorney on your behalf. A CPA can appear at audit meetings, correspond with the IRS, and represent you in IRS Appeals on unagreed issues. For a routine audit with no fraud indicators and no criminal exposure, a CPA is a fully appropriate representative. The question of when you need an attorney instead comes down to privilege, criminal exposure, and Tax Court access — not IRS representation rights in a standard audit.
Is attorney-client privilege important for a tax audit?
It depends on the nature of the audit. For a straightforward correspondence audit over a specific income item or deduction, privilege typically does not change the outcome. For an audit with fraud indicators — cash transactions, unexplained deposits, prior audit history — or where the examiner is asking questions that suggest they are building a civil fraud or eggshell audit case, what you say to your representative and how you say it matters significantly. In those situations, the protection of attorney-client privilege is a material difference between having a CPA and having a tax attorney on the case. Once the IRS's interest shifts from civil tax to potential criminal liability, privilege becomes the most important thing you have.
What is an LL.M. in Taxation?
An LL.M. (Master of Laws) in Taxation is a one-year post-J.D. graduate degree in tax law. It is distinct from a J.D. (the general law degree) and from a CPA credential (an accounting license). The LL.M. in Taxation covers federal income tax, corporate and partnership taxation, international tax, estate and gift tax, and tax procedure in depth. It is the standard advanced credential for attorneys who practice tax law as their primary focus. I hold a J.D., an LL.M. (Taxation), and an MBA — the combination covers the legal, tax-technical, and business dimensions of complex tax matters.
When should I call a tax attorney instead of my CPA?
Call a tax attorney when the matter becomes a legal dispute rather than a compliance question. Specific triggers: a CI special agent contacts you; you receive a Notice of Deficiency and are considering Tax Court; the IRS has filed a lien or issued a levy; your audit has shifted from routine questions to questions about intent, fraud, or unreported income; you have foreign accounts or assets with disclosure questions; or you are evaluating an Offer in Compromise and want the analysis done before filing. In those situations, the legal strategy, the privilege protection, and the court access that a tax attorney provides become material to the outcome.
Can my CPA and tax attorney work together?
Yes — and in most complex matters, that is the right structure. The attorney handles the legal representation, the dispute strategy, the government communications, and the privilege analysis. The CPA handles the accounting records, return preparation, and ongoing compliance. For matters where I need detailed accounting work done as part of the legal strategy, I use a Kovel arrangement — a formal retention of the CPA by my firm — so the CPA's work product is protected by attorney-client privilege. If your existing CPA is experienced with your books and your business, keeping them involved for the accounting side while bringing in a tax attorney for the dispute side is often the most efficient arrangement.
