Do I need a tax attorney to deal with the IRS?

Do you need a tax attorney? What one does, and when it matters

You don't need a lawyer to answer an IRS letter, set up a payment plan or file a petition in the Tax Court. Many people do those things themselves. A tax attorney is a lawyer, licensed by a state, who handles tax disputes: audits and appeals, collection (levies, liens, payment plans and offers), cases in the U.S. Tax Court and other courts, and criminal tax investigations. Attorneys, CPAs and enrolled agents can all represent you before the IRS. The table shows where each problem starts:

When a tax attorney fits best, on the official rules:

• A criminal investigation. IRS special agents investigate possible tax crimes, and those cases can be referred to the Department of Justice for prosecution. The confidentiality privilege that covers CPAs and enrolled agents applies only in noncriminal tax matters (26 U.S.C. § 7525(a)(2)).
• A court case. In the Tax Court you may represent yourself, or be represented by a private attorney, a clinic representative or another person admitted to practice before the Court.
• Several problems at once, such as an audit that turns into a notice of deficiency, or a lien and a levy on the same years. Each step has its own deadline.
• A low income or a hardship. A Low Income Taxpayer Clinic or the Taxpayer Advocate Service may help for free (free help).

Your deadline: which IRS letter did you get?

The letter in your hand sets the clock, and some deadlines cannot be extended. The Tax Court says it cannot extend the time to petition after a notice of deficiency, and it cannot consider a late petition. Each row was read from the Internal Revenue Code, Treasury regulations or the IRS on November 2, 2026:

• A timely hearing request pauses the levy, and the 10-year collection clock, while the hearing and any appeal are pending (26 U.S.C. § 6330(e)(1)). You can take the determination to the Tax Court.
• An equivalent hearing is held by Appeals like a Collection Due Process hearing, but it ends with a decision letter instead of a notice of determination, and only determinations from Collection Due Process hearings can go to the Tax Court (Treas. Reg. § 301.6330-1(i)).
• Use Form 12153 for either hearing, sent to the hearing address on your notice, not the payment address. Keep a copy and proof of the date you sent it.
• A last day on a Saturday, Sunday or legal holiday in the District of Columbia: an act the tax laws require is on time if it is done on the next day that is not one (26 U.S.C. § 7503). The calculator below shows the date the count gives; check the calendar.
• The Tax Court filing fee is $60, and the court may waive it if you show you cannot pay. U.S. Tax Court: Starting a case

The IRS clocks: the 3-year rule, 10 years to collect, and refunds

What is the 3-year rule? The IRS generally has 3 years after you file a return to assess more tax. A return filed early counts as filed on its due date. Once tax is assessed, the IRS has 10 years to collect it (the collection statute expiration date). To claim a refund, you have 3 years from filing or 2 years from paying, whichever is later.

• Some events stop or extend these clocks. You and the IRS can agree in writing to extend the time to assess (26 U.S.C. § 6501(c)(4)); a Collection Due Process hearing pauses the 10-year clock (§ 6330(e)(1)); and the IRS extends the collection period while it considers an offer in compromise.
• Your tax account transcript shows basic data from your return and the changes made after you filed it. Get it free from your IRS online account, by mail, or by calling 800-908-9946 (allow 5 to 10 calendar days by mail).
• Keep your records for 3 years in most cases, 6 years if you left off more than 25% of the gross income on your return, and indefinitely if you did not file or filed a fraudulent return, the IRS says.

Tax attorney, CPA or enrolled agent: who can represent you before the IRS

Attorneys, CPAs and enrolled agents have unlimited representation rights before the IRS: they may represent you on any matter, including audits, payment and collection issues, and appeals, the IRS says. Other paid preparers have limited rights at most. You authorize a representative by signing Form 2848, which lists their licensing state or authority and their bar, license or enrollment number. 31 C.F.R. § 10.3 (Circular 230)

• The privilege for CPAs and enrolled agents stops at criminal matters. The confidentiality that protects what you tell an attorney also covers a CPA or an enrolled agent, but only in noncriminal tax matters before the IRS and noncriminal tax cases in federal court.26 U.S.C. § 7525(a)
• In the Tax Court: you, or a person admitted to it. You may file a petition and present your case yourself. A representative must be admitted to practice before the Tax Court, such as a private attorney or a clinic representative.U.S. Tax Court: Starting a case
• Form 2848 gives your representative access. The person you authorize must be eligible to practice before the IRS, and can then receive and inspect your confidential tax information. A student in a Low Income Taxpayer Clinic can represent you under a special authorization from the Taxpayer Advocate Service.IRS: About Form 2848
• You have the right to a representative. Taxpayers have the right to retain an authorized representative of their choice in their dealings with the IRS.IRS Publication 1, Taxpayer Bill of Rights

If you owe: payment plans, an offer in compromise, and hardship status

Many people can set up an IRS payment plan themselves, online, without a representative. Individuals may apply online for a long-term plan if they owe $50,000 or less in combined tax, penalties and interest and have filed all required returns, or for a short-term plan if they owe less than $100,000. Penalties and interest keep adding up until the balance is paid in full. IRS: Payment plans

An offer in compromise settles the debt for less than the full amount, but only when you can't pay in full. The IRS generally won't accept an offer if you can pay through a payment plan or the equity in your assets. Every offer needs a $205 application fee and a first payment: 20% of a lump-sum offer, with the rest in five or fewer payments, or the first payment of a periodic offer (26 U.S.C. § 7122(c)). If you certify low income on Form 656, you pay neither while the IRS considers it (the income lines). The fee for a rejected offer is not returned. The IRS Offer in Compromise Pre-Qualifier tool checks your eligibility for free.

How much does the IRS usually settle for? The IRS does not publish a typical percentage, and no one can honestly promise one. In fiscal year 2025 taxpayers proposed 38,797 offers in compromise; the IRS accepted 5,464 of them, for a total of $98.1 million. IRS Data Book, 2025 (Publication 55B), Table 4-1

• Hardship: currently not collectible. If you cannot pay because of financial hardship, the IRS may suspend most collection until your situation improves. You still owe the full debt, and penalties and interest keep accruing. It may ask for Form 433-F or Form 433-A first.IRS: Temporarily delay the collection process
• Innocent spouse relief: about 2 years. If your spouse or former spouse understated the tax on a joint return and you did not know, ask for relief on Form 8857. The law allows 2 years after the IRS begins collection activities against you; the IRS says to ask within 2 years of an IRS notice of an audit or taxes due because of an error on your return, and as soon as you learn of the taxes due.26 U.S.C. § 6015(b)(1)(E) · IRS: Innocent spouse relief
• A partial payment plan. If you cannot pay in full by the collection statute expiration date (generally 10 years), you may qualify for a partial payment plan, with a financial statement and reviews every two years.IRS Publication 594

What filing late and paying late add to the bill

Filing late usually costs more than paying late. The failure-to-file penalty is 5% of the unpaid tax for each month or part of a month the return is late, up to 25%. The failure-to-pay penalty is 0.5% a month, up to 25%. Neither applies if you show the failure was due to reasonable cause and not willful neglect (26 U.S.C. § 6651(a)).

What does a tax attorney cost?

No law or court sets a price for a tax attorney. What the federal rules set is how anyone who practices before the IRS may charge. Under Circular 230, a practitioner may not charge an unconscionable fee, and generally may not charge a contingent fee (for example a percentage of the refund or of the taxes saved) for any matter before the IRS. 31 C.F.R. § 10.27

• The three exceptions. A contingent fee is allowed for an IRS examination of, or challenge to, an original return, or an amended return or refund claim filed within 120 days of a written notice of the examination; for a refund claim only about statutory interest or penalties; and for any court case arising under the Internal Revenue Code.31 C.F.R. § 10.27(b)
• Get the fee terms in writing. Under the ABA model rule, a lawyer tells you the basis of the fee, preferably in writing, and a contingent fee must be in a writing you sign.ABA Model Rule 1.5
• Free help may fit first. A Low Income Taxpayer Clinic charges nothing or a small fee, and the Taxpayer Advocate Service is free (free help).26 U.S.C. § 7526

Can I call a lawyer and ask a question for free? Some lawyers offer a free first consultation, so ask before the meeting. Bar-run referral services connect you with a lawyer for your kind of problem. The ones this guide has checked publish a first-consultation price: the State Bar of Texas service up to $20 for up to 30 minutes, The Florida Bar service up to $25 for 30 minutes, and the New York State Bar Association service normally $35 for the first half hour; California certifies its referral services, which you search by county. See Find a lawyer or free legal aid for the details.

Red flags: offer-in-compromise mills and fake IRS calls

The IRS lists aggressive or misleading offer-in-compromise marketing, "OIC mills", among its Dirty Dozen tax scams for 2026. They often overpromise results and charge high fees to people who don't qualify. You can check your eligibility for free with the IRS Offer in Compromise Pre-Qualifier tool. IRS: Dirty Dozen tax scams for 2026

• A promised result or a set percentage. The IRS weighs each offer against your income, expenses and asset equity.
• A contingent fee for an offer or a payment plan. Circular 230 allows one only in the three cases above.
• Someone who is not an attorney, CPA or enrolled agent offering to handle your collection case or appeal. Other preparers cannot represent you there.
• A call, text or email that rushes or threatens you. The IRS normally contacts you first by mail. A contact is not from the IRS if it is unexpected, rushes you, threatens you, asks for personal or financial information, or demands payment now; impersonators threaten arrest or deportation. See how to know it's the IRS, and Identity theft if someone filed in your name.

Free help: Low Income Taxpayer Clinics and the Taxpayer Advocate

Low Income Taxpayer Clinics represent people with low incomes in audits, appeals and collection disputes, before the IRS and in court, for free or a small fee. They are independent from the IRS. Generally your income must be at or below 250% of the federal poverty guidelines, and the amount in dispute is usually less than $50,000; each clinic decides. Find one in IRS Publication 4134 or with the clinic finder of the Taxpayer Advocate Service. 26 U.S.C. § 7526 · Taxpayer Advocate Service: LITC

The 2026 income ceilings (250% of the federal poverty guidelines), by size of family, as the Taxpayer Advocate Service publishes them:

The same amounts are the low-income line on Form 656 for an offer in compromise: if your adjusted gross income on your latest return, or your household's gross monthly income × 12, is at or under the line for your family size, you pay no $205 fee and no offer payments while the IRS considers your offer. Form 656 (Rev. 4-2026), Low-Income Certification

The Taxpayer Advocate Service is free and independent within the IRS. It may help if an IRS problem is causing you financial hardship (you could lose your home, food, utilities or transportation to work), if an IRS process or system has failed (for example a delay more than 30 days past normal processing), or if you are not being treated fairly. An Advocate makes the final decision. Call 877-777-4778.

Check a lawyer's license in your state before you hire

Check the license before you sign a fee agreement or a Form 2848. For a tax attorney, use the official search of the state that licensed them; Form 2848 asks your representative for that state and the bar number.

Lawyers are licensed by a state agency in each state, and that agency can tell you whether a person has a law license and may practice there, the American Bar Association says. Its list names the agency in every state: in some it is the state bar, in others the state's highest court or one of its agencies. The table below gives each one, with a link where the site is a government or state-bar site this guide links to. ABA: Lawyer Licensing

• Search the exact name on the license, and check that the status is active and the person is allowed to practice now.
• Look for public discipline. Many of these searches show it, and the same agency handles complaints about lawyers.
• A lawyer from another state usually cannot handle a case in your state's courts unless the court lets them in for that case.
• A business name is not a license. Ask for the lawyer’s own name and check that person, not the firm.

To check a CPA, use the license search of your state's board of accountancy, a state agency: for example the California Board of Accountancy or New York's Office of the Professions verification search. To check an enrolled agent, use the IRS Office of Enrollment contact form and choose that you are requesting information about an enrolled agent; the IRS aims to answer within 72 hours. IRS: Verify the status of an enrolled agent

The IRS Directory of Federal Tax Return Preparers with Credentials and Select Qualifications lists the attorneys, CPAs and enrolled agents with a valid preparer tax identification number (PTIN), and every Annual Filing Season Program participant. Find it from the IRS page Choosing a tax professional.

Your first meeting with a tax attorney: what to bring and ask

Bring every IRS letter in date order, with its notice number and your deadline written on top. A lawyer can tell you much more in one meeting with the letters in front of them. Ask:

• “Is your license active, in which state, and are you admitted to practice before the Tax Court?”
• “Which of my letters is the most urgent, and what is my last day?”
• “Should I answer this myself, or should you, under a Form 2848?”
• “Do I fit a payment plan, an offer in compromise or hardship status?”
• “How is your fee figured, and will you put it in writing?”
• “If this could become a criminal matter, what should I not say or sign?”
