Yes, tax evasion is a federal crime. Under 26 U.S.C. § 7201 it is a felony to willfully attempt to evade or defeat a federal tax, with up to 5 years per count. Filing a false return is a separate felony, and willfully failing to file is a misdemeanor. Most tax charges must be brought within 6 years.
What does the law make illegal?
This page is about criminal tax charges: cases where federal prosecutors say someone broke the tax laws on purpose. It does not cover tax preparation, audits or civil disputes with the IRS. The main crimes are in Title 26 of the U.S. Code, the Internal Revenue Code:
- Tax evasion (26 U.S.C. § 7201): willfully attempting in any manner to evade or defeat a tax or its payment. The Supreme Court has described three elements: willfulness, a tax deficiency (tax was owed), and an affirmative act of evasion (Sansone v. United States, 380 U.S. 343 (1965)). Examples of affirmative acts the Court has given include keeping a double set of books, making false entries or invoices, destroying records, concealing assets, and covering up sources of income (Spies v. United States, 317 U.S. 492 (1943)).
- False return (26 U.S.C. § 7206(1)): willfully signing a return or other document made under penalty of perjury that the person does not believe is true and correct as to every material matter. It does not list a tax deficiency as an element.
- Aiding or assisting a false return (§ 7206(2)): willfully helping prepare or present a return or other document that is false as to a material matter, whether or not the taxpayer knows. It is often charged against return preparers.
- Willful failure to file, pay or keep records (26 U.S.C. § 7203): willfully failing to file a required return, pay a tax, keep required records or supply required information on time.
- Obstructing the IRS (26 U.S.C. § 7212(a)): corruptly, or by force or threats, trying to intimidate or impede an IRS officer or employee, or to obstruct or impede the due administration of the tax laws.
Tax conspiracy
When two or more people are accused of working together, prosecutors may add a charge under the general conspiracy law, 18 U.S.C. § 371, either for conspiring to commit a tax crime or for conspiring to defraud the United States by impeding the IRS. It carries up to 5 years. See our federal conspiracy page. Tax cases can also include mail, wire or bank fraud, money laundering or identity theft counts; see our wire fraud and mail fraud page and money laundering page, and our white collar crime page for related charges.

What does "willfully" mean in a tax case?
Almost every tax crime requires that the person acted "willfully." In Cheek v. United States, 498 U.S. 192 (1991), the Supreme Court held that willfulness in the tax laws means the voluntary, intentional violation of a known legal duty. That standard protects people from prosecution for honest mistakes made because the tax laws are complex.
- A good-faith misunderstanding is a defense. If the jury believes the person truly misunderstood the law, or truly believed he was not breaking it, the government has not proved willfulness, even if the belief was unreasonable. The jury can still weigh evidence that he knew his legal duties.
- Disagreeing with the law is not. In the same case, the Court held that a belief that the tax laws are unconstitutional is not a defense to willfulness, because it shows the person knew what the law required.
What does IRS Criminal Investigation do?
IRS Criminal Investigation (often called IRS-CI) is the IRS division whose special agents investigate possible crimes under the tax laws and related Title 18 crimes, such as false claims, conspiracy and mail fraud. Cases often begin with a fraud referral from an IRS auditor or revenue officer, a tip from another agency or a private person, or a project CI develops itself. Special agents often work alongside revenue agents when a return is alleged to be false or was never filed (Justice Manual 6-4.110).
When an investigation is finished, the special agent writes a report recommending prosecution, which IRS lawyers review before the case is referred to the Justice Department. Once a case has been referred to the Justice Department for a grand jury investigation or prosecution, the IRS may not issue an administrative summons to that person (26 U.S.C. § 7602(d)). From then on, evidence is usually gathered by grand jury subpoena.
Who decides whether to bring tax charges?
Federal prosecutors decide, after a central review inside the Justice Department. The Justice Manual says a U.S. Attorney's Office may use a grand jury to investigate tax crimes, and may seek an indictment on tax charges, only after that review authorizes it (Justice Manual 6-1.110, 6-4.120). The Manual assigns that review to the Justice Department's Tax Division.
The Department's current regulations assign "all criminal proceedings arising under the internal revenue laws" to its National Fraud Enforcement Division (28 C.F.R. § 0.70(b)), while the tax chapters of the Justice Manual still refer to the Tax Division. The Manual also says that, if time and circumstances permit, a written request for a conference is generally granted, and the person or a lawyer can present explanations or evidence before the decision on prosecution (Justice Manual 6-4.214).
Where is the line between a civil tax problem and a tax crime?
Most tax disputes are civil: the IRS audits a return, assesses tax, and adds interest and penalties. What turns a tax problem into a crime is willfulness. The same unpaid tax can lead to a civil assessment for one person and a criminal charge for another, depending on what each knew and did. We handle the criminal side only and do not give civil tax or tax preparation advice.
Paying the tax later does not by itself end a criminal case. Justice Department policy is to review proposed criminal tax cases without considering civil liability or the collection of taxes, and civil settlement is usually put off until after sentencing (Justice Manual 6-4.360). Restitution and payment can still matter, especially at sentencing.
What are the penalties?
| Charge | Maximum prison | Maximum fine |
|---|---|---|
| Tax evasion (§ 7201) | 5 years | $100,000 in the statute; up to $250,000 under 18 U.S.C. § 3571 |
| False return; aiding or assisting (§ 7206(1), (2)) | 3 years | $100,000 in the statute; up to $250,000 under 18 U.S.C. § 3571 |
| Obstructing the IRS (§ 7212(a)) | 3 years (1 year if only by threats of force) | $5,000 in the statute ($3,000 for threats only); up to $250,000 under 18 U.S.C. § 3571 for the felony |
| Willful failure to file, pay or keep records (§ 7203) | 1 year (5 years for willful § 6050I cash-reporting violations) | $25,000 in the statute; up to $100,000 under 18 U.S.C. § 3571 for a Class A misdemeanor |
| Tax conspiracy (18 U.S.C. § 371) | 5 years | $250,000 |
- Mandatory minimum: none. The judge sentences under the Sentencing Guidelines and 18 U.S.C. § 3553(a).
- Fines: the general fine law also allows a fine of up to twice the gross gain or loss (18 U.S.C. § 3571(d)).
- Restitution: the court can order restitution to the extent a plea agreement provides for it (18 U.S.C. § 3663(a)(3)), and can make payment a condition of probation or supervised release (18 U.S.C. §§ 3563(b), 3583(d)).
- Supervised release: up to 3 years after a 5-year offense such as evasion (a Class D felony), and up to 1 year after a 3-year offense such as a false return (a Class E felony) or a misdemeanor (18 U.S.C. §§ 3559(a), 3583(b)).
How long does the government have to charge it?
The general limit for tax crimes is 3 years, but 26 U.S.C. § 6531 sets 6 years for the main tax charges: evasion, false returns under § 7206(1), aiding or assisting false returns, willful failure to file or pay, § 7212(a), conspiracies to defraud the United States, and conspiracies to evade tax. Time the person spends outside the United States, or as a fugitive, does not count. If a criminal complaint is filed within the limit, the government gets until 9 months after the complaint to indict.
How does sentencing work for this charge?
Evasion, false returns and failure to file are sentenced under USSG §2T1.1. Aiding or assisting false returns under § 7206(2) is sentenced under USSG §2T1.4. Both start from the tax table in USSG §2T4.1, which sets the offense level by the "tax loss," or level 6 if there is no tax loss.
- Tax loss is the loss that was the object of the offense, meaning what would have been lost if it had succeeded. For underreported income, the guideline treats the loss as 28% of the unreported gross income (34% for a corporation), plus any false credits, unless a more accurate figure can be shown (§2T1.1(c)(1)).
- Income from crime: +2 levels, to at least level 12, if the person failed to report or correctly identify more than $10,000 a year in income from criminal activity (§2T1.1(b)(1)).
- Sophisticated means: +2 levels, to at least level 12 (§2T1.1(b)(2); §2T1.4(b)(2)).
- Return preparers: +2 levels under §2T1.4 if the person was in the business of preparing returns, or the offense was part of a pattern that provided a substantial part of his income (§2T1.4(b)(1)).
- Obstruction under § 7212(a): Appendix A points to §2A2.4 for force or threats, and to §2J1.2 or §2T1.1 for the "omnibus clause."
A timely guilty plea usually earns 2 or 3 levels off (USSG §3E1.1). The guidelines are advisory, but the judge must calculate them correctly.
Scheduled change, November 1, 2026. Amendments the Sentencing Commission sent Congress on April 30, 2026 are scheduled to take effect November 1, 2026, unless Congress acts. They raise every dollar amount in the §2T4.1 tax table for inflation, the first update since 2015; for example, level 6 will cover a tax loss of $3,500 or less instead of $2,500. They also replace the multiple-count rules with a single guideline, §3D1.1. A judge generally applies the manual in effect on the sentencing date (USSG §1B1.11). (U.S. Sentencing Commission, 2026 amendments)
Pending at the Supreme Court. In Beaird v. United States, No. 25-5343, set for argument on October 13, 2026, the Court agreed to decide whether Stinson v. United States (1993) still states the rule for how much weight courts must give the Guidelines’ commentary, the notes that follow each guideline. The answer could affect rules on this page that come from commentary rather than from the guideline text itself.
Guideline numbers on this page are from the Guidelines Manual in effect since November 1, 2025, which no longer uses “departures”: the judge calculates the range, then weighs the factors in 18 U.S.C. § 3553(a). For more depth, see How the federal Sentencing Guidelines work, at Sentencing.net, a Criminal Center site.
Statutes covered on this page
Each federal law this page covers, listed by how often it was a statute of conviction in fiscal year 2025 (U.S. Sentencing Commission data). For each one: the official section heading, what the government must prove, the penalties, and the sentencing guideline the Commission's Statutory Index assigns to it. See all statutes by title and section.
26 U.S.C. § 7206(1): False return or statement under penalty of perjury
Official heading of 26 U.S.C. § 7206: “Fraud and false statements”
What the government must prove
- The person made and signed a return, statement or other document.
- It contained, or was verified by, a written declaration that it was made under penalty of perjury.
- The person did not believe it was true and correct as to every material matter.

Penalties. A felony with up to 3 years per count, a fine of up to $100,000 ($500,000 for a corporation) or up to $250,000 under 18 U.S.C. § 3571, and the costs of prosecution. The time limit is 6 years (26 U.S.C. § 6531(5)).
Sentencing guideline. Appendix A assigns USSG §2T1.1 and §2S1.3. Tax cases are sentenced under §2T1.1. Details under Sentencing.
Unlike evasion, § 7206(1) does not list a tax deficiency as an element, so the government does not have to prove that tax was owed.
26 U.S.C. § 7206(2): Aiding or assisting a false return
Official heading of 26 U.S.C. § 7206: “Fraud and false statements”
What the government must prove
- The person aided, assisted, procured, counseled or advised the preparation or presentation of a return, affidavit, claim or other document under the tax laws.
- The document was false or fraudulent as to a material matter. The taxpayer does not have to know about the falsity.
- The person acted willfully.
Penalties. A felony with up to 3 years per count, a fine of up to $100,000 ($500,000 for a corporation) or up to $250,000 under 18 U.S.C. § 3571, and the costs of prosecution. The time limit is 6 years (26 U.S.C. § 6531(3)).
Sentencing guideline. Appendix A assigns USSG §2T1.4 and §2S1.3. Under §2T1.4, the tax loss is the loss from the returns the person helped prepare, with +2 levels for someone in the business of preparing returns.
26 U.S.C. § 7201: Tax evasion
Official heading of 26 U.S.C. § 7201: “Attempt to evade or defeat tax”
What the government must prove
- Tax was owed (a tax deficiency), or the person attempted to evade the payment of a tax already due.

A willful violation of the cash-reporting rules in 26 U.S.C. § 6050I is a felony with up to 5 years. The time limit for failing to file or pay is 6 years (26 U.S.C. § 6531(4)).
Sentencing guideline. Appendix A assigns USSG §2T1.1 and §2S1.3. §2T1.1 is the guideline for willful failure to file a return, and §2S1.3 covers failures to report cash transactions.
The statute does not apply to a failure to pay estimated tax when no addition to tax applies under 26 U.S.C. §§ 6654 or 6655.
26 U.S.C. § 7212(a): Corruptly or forcibly obstructing the IRS
Official heading of 26 U.S.C. § 7212: “Attempts to interfere with administration of internal revenue laws”
What the government must prove
- The person corruptly, or by force or threats of force, tried to intimidate or impede an IRS officer or employee acting officially; or
- the person corruptly, or by force or threats of force, obstructed or impeded, or tried to obstruct or impede, the due administration of the tax laws (the "omnibus clause").
- Under the omnibus clause, there must be a nexus to a particular proceeding, such as an investigation or audit, that was pending or reasonably foreseeable when the person acted. Routine IRS work, such as processing returns, is not enough (Marinello v. United States, 584 U.S. 1 (2018)).
Penalties. Up to 3 years and a $5,000 fine in the statute (up to $250,000 under 18 U.S.C. § 3571 for the felony); if the offense is committed only by threats of force, up to 1 year and a $3,000 fine. The time limit is 6 years (26 U.S.C. § 6531(6)).
Sentencing guideline. Appendix A assigns USSG §2A2.4 to § 7212(a) and §2J1.2 or §2T1.1 to the omnibus clause.
How do these cases usually start and move?
Many tax cases start as civil audits. If an auditor sees signs of fraud, the case can be referred to IRS Criminal Investigation. Other cases start with a tip, a bank or cash-transaction report, or a related fraud investigation. Some people first learn of a criminal tax investigation when special agents show up to ask questions; others when a grand jury subpoena or a target letter arrives (Justice Manual 9-11.151).
What to do now
- If special agents ask to talk, it is generally wise to speak with a criminal defense lawyer first. Statements to agents are often key evidence, and a false statement can be its own crime (18 U.S.C. § 1001).
- Get advice before filing late or amended returns once you think an investigation may be under way, so the filing fits the rest of your plan.
- Keep records as they are. Destroying or altering records after learning of an investigation can be charged as obstruction.
The usual stages of a federal case
- Investigation. Agents gather records and interview witnesses, often using grand jury subpoenas. Someone the prosecutor views as a "target" may get a target letter before an indictment; a "subject" is anyone whose conduct is within the scope of the grand jury's investigation (Justice Manual 9-11.151, 9-11.153).
- Charges. A federal felony is usually charged by indictment: a grand jury decides in private whether there is probable cause (Fed. R. Crim. P. 6, 7). Some cases start with an arrest on a criminal complaint.
- First appearance and detention. After an arrest, the person goes before a magistrate judge without unnecessary delay (Fed. R. Crim. P. 5). The judge decides whether they are released or held until trial (18 U.S.C. § 3142).
- Evidence and motions. The government must turn over certain evidence (Fed. R. Crim. P. 16). The defense can ask the court to suppress evidence or dismiss charges (Fed. R. Crim. P. 12).
- Plea or trial. Many federal cases end in a guilty plea, which the judge must find knowing and voluntary (Fed. R. Crim. P. 11). At trial, the government must prove every element beyond a reasonable doubt, and a jury verdict must be unanimous (Fed. R. Crim. P. 31(a)).
- Sentencing. A probation officer writes a presentence report, and each side can object in writing within 14 days of receiving it (Fed. R. Crim. P. 32). The judge then decides the sentence under 18 U.S.C. § 3553(a).
More on what to do at each stage: Facing federal charges? What to do now.
What defense issues come up in these cases?
- Willfulness. Did the person know the legal duty and intend to violate it, or was it a mistake, a misunderstanding of complex rules, or reliance on a preparer?
- Reliance on a professional. Did the person give an accountant or preparer complete and accurate information and follow the advice?
- Tax due and tax loss. Was any tax actually owed? Were deductions, credits, basis or expenses left out of the government's numbers?
- The affirmative act. In an evasion case, what act does the government point to, and when did it happen?
- Materiality. Was the false item on a return material, or a harmless error?
- After Marinello. In a § 7212(a) omnibus-clause case, was there a pending or foreseeable proceeding, and did the person know of it?
- Time limits. When did each offense occur, and was it charged within 6 years?
Every case turns on its own facts. These are issues to look at, not predictions about how any case will turn out.
What happens after a conviction?
- Appeal. A notice of appeal is usually due within 14 days after the judgment is entered (Fed. R. App. P. 4(b)(1)(A)). Many plea agreements waive the right to appeal, but in Hunter v. United States (2026) the Supreme Court held that a waiver can’t be enforced when doing so would cause a miscarriage of justice, a high bar. See how federal criminal appeals work and federal appeals at Sentencing.net.
- A § 2255 motion. A motion asking the sentencing court to vacate, set aside or correct the sentence, for example for ineffective assistance of counsel. It is usually due within one year after the conviction becomes final (28 U.S.C. § 2255(f)). See 2255motion.com.
- Compassionate release. A motion asking the judge to reduce a prison sentence for extraordinary and compelling reasons, filed after the person asks the warden and either exhausts BOP appeals or waits 30 days (18 U.S.C. § 3582(c)(1)(A)). It can’t be used to attack the validity of the conviction itself (Fernandez v. United States (2026)). See CompassionateRelease.com.
- Clemency. The President can pardon a federal offense or commute (shorten) a federal sentence (U.S. Const. art. II, § 2). See Clemency.com.
Common questions
Is tax evasion a federal crime?
Yes. Willfully attempting in any way to evade or defeat a federal tax, or its payment, is a felony under 26 U.S.C. § 7201. It carries up to 5 years in prison per count, a fine of up to $100,000 in the statute or $250,000 under 18 U.S.C. § 3571, and the costs of prosecution.
What is the statute of limitations for tax evasion?
Six years from the offense (26 U.S.C. § 6531(2)). The same 6-year limit applies to false returns, aiding or assisting false returns, and willful failure to file or pay. Time the person spends outside the United States or as a fugitive does not count toward the 6 years.
What is the difference between tax evasion and tax fraud?
Tax evasion is a specific crime under 26 U.S.C. § 7201: willfully trying to evade a tax that is owed through an affirmative act, with up to 5 years per count. "Tax fraud" usually means filing a false return under penalty of perjury (26 U.S.C. § 7206(1)) or helping prepare one (§ 7206(2)), with up to 3 years per count. A false-return charge does not require proof that tax was owed.
What does IRS Criminal Investigation do?
IRS Criminal Investigation is the IRS division whose special agents investigate suspected crimes under the tax laws and related federal crimes. When agents conclude a case should be prosecuted, they write a report that IRS lawyers review, and the IRS refers the case to the Justice Department, which decides whether to bring charges (Justice Manual 6-4.110).
