Hire a tax attorney when your tax problem is legal: possible fraud or criminal exposure, a case heading to the U.S. Tax Court or federal court, a large disputed balance, or liens and levies that threaten your home or business. Hire a CPA when the problem is the numbers: messy books, amended returns, business filings or tax planning. For routine IRS notices, payment plans and penalty relief, an enrolled agent (EA) or CPA is usually enough and costs less. All three can represent you before the IRS, but only an attorney gives you attorney-client privilege that still holds if a case turns criminal. This guide compares the three, explains what privilege really covers, sets out typical cost ranges, and shows how to choose.
Tax attorney vs CPA vs enrolled agent at a glance
| Professional | Credential | IRS representation | Confidentiality | Best for |
|---|---|---|---|---|
| Tax attorney | Law degree and state bar admission, often an LL.M. in taxation | Unlimited, plus court litigation | Attorney-client privilege, including in criminal matters | Criminal exposure, litigation, large disputes, complex resolution |
| CPA | State board license after exam and experience | Unlimited | Limited federal practitioner privilege (section 7525), not in criminal matters | Bookkeeping problems, business returns, amended returns, planning, audits |
| Enrolled agent | IRS credential by exam or qualifying IRS service | Unlimited | Same limited section 7525 protection | Notices, payment plans, penalty relief, straightforward exams |
Because all three have the same unlimited rights to represent you before the IRS, the credential alone does not decide the question. The deciding factors are privilege, the risk of court, and whether the underlying records need rebuilding.
What privilege covers, and where section 7525 stops

Section 7525 of the Internal Revenue Code extends a confidentiality privilege to tax advice from federally authorized practitioners, which includes CPAs and enrolled agents. It sounds similar to attorney-client privilege, but it is much narrower:
- No criminal protection. It applies only to noncriminal tax matters before the IRS and noncriminal federal tax proceedings. If a case is referred for criminal investigation, conversations with your accountant can be demanded.
- Federal only. It does not cover state tax matters.
- Not return preparation. Courts have generally held that information gathered to prepare a return is not privileged.
- Easily waived. Sharing the advice with third parties can waive the protection.
Attorney-client privilege has no criminal carve-out. That is why, in sensitive cases, an attorney often hires the accountant under what is known as a Kovel arrangement, named after a 1961 federal appeals court decision. The accountant then works as the attorney’s agent, and the number crunching happens inside the privileged relationship. If you think there is any chance your situation involves willful conduct, speak to an attorney before discussing the details with anyone else. Our explainer on what “Esquire” means covers how to confirm someone is actually a licensed lawyer.
When to hire a tax attorney
- You have unreported income, unfiled returns for several years, or anything that could be viewed as intentional.
- An IRS special agent (from Criminal Investigation) contacts you, or a revenue agent suddenly stops an audit without explanation, which can signal a referral.
- You want to challenge a deficiency in the U.S. Tax Court or another federal court.
- You face a large disputed balance, a trust fund recovery penalty for unpaid payroll taxes, or complex issues such as international reporting.
- Liens or levies threaten your home, business or bank accounts and you need legal leverage.
When a CPA or enrolled agent is enough
Most IRS letters are about arithmetic, not accusations. A CP2000 notice, for example, usually means income reported to the IRS by a broker or employer does not match your return. A CPA or EA can often resolve it by providing documents or agreeing the adjustment. Similarly, a first missed deadline with a clean history may qualify for first-time penalty abatement, and a balance you cannot pay in full can often be handled with an installment agreement.
A CPA is the better choice when your books need rebuilding, you run a business, or you need amended returns and forward planning. An EA specializes in IRS procedure and is often the lowest-cost competent option for notices and collection issues. Many businesses already rely on CPAs for this work; see how CPAs support healthcare practices with compliance and reporting for an example.
Pros and cons of each option
Tax attorney
- Pros: strongest privilege, can litigate, carries weight in negotiations because court is a real option.
- Cons: usually the most expensive; overkill for routine notices.
CPA
- Pros: fixes the underlying records, prepares amended returns, speaks the examiner’s accounting language.
- Cons: limited protection if a matter turns criminal; not a litigator.
Enrolled agent
- Pros: typically the lowest fees, focused on IRS procedure, some are former IRS employees.
- Cons: cannot go to court (except Tax Court if separately admitted); not suited to complex legal or accounting disputes.
What a tax attorney costs compared with a CPA
Fees vary by city, complexity and experience, so treat these as broad ranges commonly quoted by U.S. practitioners rather than fixed prices:
| Professional or service | Typical range |
|---|---|
| Tax attorney hourly rate | Often a few hundred dollars an hour, higher in major cities and for specialists |
| CPA hourly rate | Often somewhat lower than an attorney, varies by firm |
| Enrolled agent hourly rate | Usually the lowest of the three |
| Installment agreement or penalty abatement | Often a flat fee in the low thousands or less |
| Offer in compromise or complex audit defense | Often several thousand dollars or more |
A practical rule: if you owe a modest amount, nothing is in dispute and there is no criminal angle, an attorney’s fee rarely pays for itself. Once a summons, lien, fraud question or large disputed amount appears, the fee usually looks small next to the exposure. Always get the fee structure in writing, including what happens if the case goes to appeals.
How IRS collection escalates

The IRS publishes annual figures on audits, collections and enforcement in its IRS Data Book. The odds of any one return being audited are low, but unpaid balances follow a predictable path:
- Notices and demand for payment: a series of letters with growing urgency, while penalties and interest accrue.
- Federal tax lien: a legal claim against your property, including real estate and personal property (see our chattel definition guide for what counts), which can hurt your ability to sell or borrow.
- Final notice of intent to levy: you generally have 30 days to request a Collection Due Process hearing. Missing that window is one of the costliest mistakes in the process.
- Levies: the IRS can take wages, bank accounts and other assets.
How to vet a tax professional before paying a retainer
- Check the attorney’s standing with the state bar, or the CPA’s license with the state board of accountancy. Both are public.
- Ask what share of the practice is tax controversy work, not just tax preparation or estate planning.
- Look for an LL.M. in taxation or prior IRS or Department of Justice experience.
- Ask who will actually handle your file day to day.
- Avoid anyone who guarantees you will settle for “pennies on the dollar” before reviewing your IRS transcripts. The IRS has repeatedly warned about offer in compromise “mills” that overpromise.
Verdict: who to hire

If the facts could hurt you under oath, hire a tax attorney, and do it early. If the facts are fine and the records are the problem, a CPA is better value. If you simply need someone to answer the IRS and set up a payment plan, an enrolled agent has the same representation rights at a lower rate. Whichever you choose, start by downloading your IRS account transcripts from your IRS online account: they list every assessment, penalty and deadline, and make the first consultation far more productive.
Frequently asked questions
Is a tax attorney better than a CPA?
Not in general. A tax attorney is better for legal risk, litigation and anything with possible criminal exposure. A CPA is better for accounting problems, business returns and planning.
Is a tax attorney worth the cost?
It is usually worth it when the downside is legal, such as a fraud penalty, a lien on your home or a criminal referral. For a small undisputed balance, a CPA or enrolled agent is normally more cost-effective.
Can a CPA represent me in Tax Court?
Only if they pass the Tax Court’s separate exam for non-attorneys. Before the IRS itself, CPAs and enrolled agents have the same unlimited representation rights as attorneys.
Are my conversations with a CPA privileged?
Partly. Section 7525 protects some federal tax advice from CPAs and enrolled agents, but not in criminal matters, state matters or return preparation.
What should I do if I have unfiled returns?
If several years are missing, especially with significant income, speak to a tax attorney first, who can then bring in a CPA or preparer under a privileged arrangement if needed.
