Owing money to the IRS is not a crime. Being unable to pay is not a crime. What can be a crime is willfully refusing to file, or taking deliberate steps to hide income or assets from the government.
This page sets out what the statutes say, what the Supreme Court says about willfulness, how often taxpayers are prosecuted, and what the far more likely outcome looks like.
No, and the Supreme Court said so in terms. In Spies v. United States, 317 U.S. 492 (1943), the Court wrote that “in view of our traditional aversion to imprisonment for debt, we would not without the clearest manifestation of Congressional intent assume that mere knowing and intentional default in payment of a tax where there had been no willful failure to disclose the liability is intended to constitute a criminal offense of any degree.”
The Court added that willfulness in a nonpayment case would “include some element of evil motive and want of justification in view of all the financial circumstances of the taxpayer.” A person who reported the tax honestly and simply does not have the money lacks that element.
One caution worth stating plainly. 26 U.S.C. § 7203 does make willful failure to pay a misdemeanor on its face, punishable by up to one year, and it does reach these taxpayers. Prosecutors rarely bring that charge against someone who disclosed the liability and genuinely lacks the funds because those facts can make willfulness difficult to prove. Department of Justice policy generally reserves § 7203 for cases in which the taxpayer willfully failed to comply with a tax requirement but did not also engage in conduct intended to evade the tax or obstruct the IRS.
Willfulness is the dividing line for every tax crime, but the elements prosecutors have to prove are not the same for each one. Felony evasion under § 7201 requires an affirmative act on top of willfulness, and both are harder to prove than they sound. Willful failure to file or pay under § 7203 is a misdemeanor that requires willfulness alone. The Department of Justice’s Criminal Tax Manual draws that line directly, describing § 7203 as requiring the government to prove only a willful failure to pay, file, or meet one of the section’s other requirements, without the affirmative act evasion demands.
The affirmative act. Spies drew the line between the felony and the misdemeanor at “the affirmative action implied from the term ‘attempt.'” The Court held that “willful but passive neglect of the statutory duty may constitute the lesser offense, but to combine with it a willful and positive attempt to evade tax in any manner or to defeat it by any means lifts the offense to the degree of felony.”
Spies gave examples, expressly non-exhaustive: keeping a double set of books, making false entries or false invoices, destroying records, concealing assets, covering up sources of income, and handling your affairs to avoid making the records usual in transactions of that kind.
Willfulness. In Cheek v. United States, 498 U.S. 192 (1991), the Court defined it as “the voluntary, intentional violation of a known legal duty.” A good-faith misunderstanding of the law negates willfulness “whether or not the claimed belief or misunderstanding is objectively reasonable.”
That sounds like a wide door. It is not. Cheek also held that a belief the tax laws are unconstitutional gets a defendant nothing, because such views “reveal full knowledge of the provisions at issue and a studied conclusion that those provisions are invalid.” Good faith about what the law requires is a defense. Disagreeing with the law is not.
Our page on what prosecutors must prove in tax evasion cases covers the elements in detail.
Five provisions do most of the work. The prison terms are per count, and a multi-year case can carry a count for each year.
| Offense | Grade | Maximum prison | Printed fine in the tax code | Actual maximum fine for an individual |
|---|---|---|---|---|
| 26 U.S.C. 7201, attempt to evade or defeat tax | Felony | 5 years per count | $100,000 | $250,000 |
| 26 U.S.C. 7202, failure to collect or pay over withheld tax | Felony | 5 years per count | $10,000 | $250,000 |
| 26 U.S.C. 7203, ordinary willful failure to file, pay, keep records, or supply information | Misdemeanor | 1 year per count | $25,000 | $100,000 |
| 26 U.S.C. 7206(1), false return signed under penalties of perjury | Felony | 3 years per count | $100,000 | $250,000 |
| 26 U.S.C. 7206(2), aiding or assisting a false return | Felony | 3 years per count | $100,000 | $250,000 |
Certain willful violations of § 6050I convert the § 7203 misdemeanor into a felony with a five-year maximum, but that exception involves cash-reporting violations distinct from the ordinary failure-to-file-or-pay scenario this page addresses.
Every one of these also carries the costs of prosecution. Restitution of the tax itself is not automatically mandated under Title 26, but federal prosecutors typically secure it through a plea agreement or as a condition of probation or supervised release.
Because a general sentencing statute overrides them. 18 U.S.C. § 3571(b) provides that an individual may be fined “the greatest of” several amounts, including $250,000 for a felony and $100,000 for a Class A misdemeanor. Section 3571(c) sets the penalty at $500,000 for an organization convicted of a felony.
Section 3571 only steps aside where the underlying statute exempts itself by specific reference, and none of the Title 26 criminal provisions do. So the $10,000 printed in § 7202 stopped being the operative ceiling decades ago. The real exposure is $250,000.
There is also a third possibility that dwarfs both. Section 3571(d) allows a fine of up to twice the gross gain or twice the gross loss where the offense produced either.
In practice, yes, by a wide margin.
Failure to file is generally easier to establish than willful failure to pay when the taxpayer filed a return reporting the liability. The government can establish nonfiling through IRS records, while a failure-to-pay prosecution requires proof that the nonpayment was willful.
The civil penalties reflect the same priority. The failure-to-file penalty runs ten times faster than the failure-to-pay penalty. Filing on time and paying late is a much better position than the reverse, even when you cannot pay a dollar. Our page on what happens if you don’t file your taxes specifically covers the non-filer situation.
Three years for most tax offenses, six years for the ones that matter most.
26 U.S.C. § 6531 sets a general three-year period, then lists eight categories that get six. Evasion under § 7201 is in paragraph (2). Willful failure to file or pay under § 7203 is in paragraph (4). False returns under § 7206(1) are in paragraph (5), and aiding or assisting under § 7206(2) is in paragraph (3).
Two parts of § 7203 stay at three years: failure to keep records and failure to supply information. The clock is also suspended while the person is outside the United States or is a fugitive.
One open question worth flagging rather than glossing. The six-year period for § 7202 is the Justice Department’s litigating position, not settled law, and it remains disputed. A Michigan case sits in the Sixth Circuit, where the issue isn’t settled as squarely as taxpayers would like.
Criminal prosecution is uncommon, and a taxpayer whose only problem is an inability to pay presents a different and generally less serious criminal profile than a taxpayer who deliberately evades the tax.
IRS Criminal Investigation publishes annual figures. For fiscal year 2025, across roughly 2,000 special agents and more than 160 million individual returns:
| Measure, fiscal year 2025 | Tax crimes | Non-tax financial crimes |
|---|---|---|
| Investigations initiated | 1,380 | 1,412 |
| Prosecutions recommended | 834 | 1,209 |
| Defendants sentenced | 589 | 1,024 |
Across all programs, the conviction rate was 89% and the incarceration rate 76%. Those numbers cut both ways. Very few cases are opened, and the ones that are opened almost always end in conviction. The place to win a criminal tax case is before it becomes one.
The program-level detail is more useful than the headline. In fiscal year 2025, the non-filer program initiated 245 investigations and sentenced 126 people, with an average of 34 months to serve. The employment tax program initiated 205 investigations and sentenced 121 people, averaging 22 months. Both programs illustrate that criminal investigations involving nonfiling and employment taxes remain relatively small in absolute numbers. The figures come from the IRS Criminal Investigation annual report.
For many federal tax offenses, tax loss is the starting point for determining the base offense level, while the statutory maximum sets the ceiling for the offense.
Federal sentencing runs through the United States Sentencing Guidelines. Section 2T1.1 sets the base offense level by reference to the tax loss table at § 2T4.1. Every threshold in that table reads “more than,” which matters at the breakpoints.
| Tax loss | Base offense level |
|---|---|
| More than $40,000 | 14 |
| More than $100,000 | 16 |
| More than $250,000 | 18 |
| More than $550,000 | 20 |
| More than $1,500,000 | 22 |
| More than $3,500,000 | 24 |
| More than $9,500,000 | 26 |
This table reflects the guideline in effect through October 2026. The Sentencing Commission adopted an inflation adjustment effective November 1, 2026 that raises the tax-loss thresholds, with the new amounts varying according to the Commission’s rounding rules. For example, the $1,500,000 breakpoint for level 22 becomes $2,000,000.
Two adjustments come up constantly. Using sophisticated means adds two levels, with a floor of level 12. Failing to report more than $10,000 of income from criminal activity adds two levels, also with a floor of 12.
One point of leverage is often missed. Under the commentary to § 2T1.1, the court should account for unclaimed credits, deductions, and exemptions in computing tax loss, provided they relate to the offense, were available at the time, are reasonably ascertainable, and are presented far enough ahead of sentencing. The burden is on the defendant. Deductions nobody ever claimed can move the loss into a lower tier, and a two-level drop is real time.
Section 2T1.1(c)(5) states that paying the tax after the offense does not reduce the tax-loss calculation. Payment may still affect other aspects of sentencing, depending on the circumstances. Our guide to criminal tax penalties and sentencing covers departures, acceptance of responsibility, and the rest of the calculation.
For almost everyone, this is the actual answer. The IRS adds penalties and interest and collects administratively.
| Penalty | Rate | Cap | Statute |
|---|---|---|---|
| Failure to file | 5% of the tax due per month or part month | 25% | 26 U.S.C. 6651(a)(1) |
| Failure to pay | 0.5% of the tax due per month or part month | 25% | 26 U.S.C. 6651(a)(2) |
| Minimum penalty, return more than 60 days late in 2026 | The lesser of $525 or 100% of the tax due | Not applicable | 26 U.S.C. 6651(a) |
| Fraudulent failure to file | 15% per month | 75% | 26 U.S.C. 6651(f) |
| Civil fraud | 75% of the underpayment attributable to fraud | Not applicable | 26 U.S.C. 6663 |
Two details are commonly reported wrong. When the failure-to-file and failure-to-pay penalties run in the same month, § 6651(c)(1) reduces the filing penalty by the payment penalty, so the combined rate is 5% per month rather than 5.5%. And § 6663(b) shifts the burden. Once the IRS establishes that any part of an underpayment is fraudulent, the entire underpayment is treated as fraudulent unless the taxpayer proves otherwise by a preponderance of the evidence.
Our page on the penalties for tax fraud covers the civil side in more depth.
A revenue agent develops an indicator of fraud into an affirmative act, and then a chain of approvals.
The Internal Revenue Manual distinguishes the two. Indicators of fraud are signs, and IRM 25.1.1.4 states, “Indications, in and of themselves, do not establish that a particular action was taken.” Affirmative acts are different, and the manual is explicit that “fraud cannot be established without affirmative acts of fraud.” Examples it gives include concealment of bank accounts or other assets, willful failure to deposit receipts into business accounts, and covering up sources of receipts.
The manual also states plainly that “avoidance of tax is not a criminal offense,” and defines evasion as requiring “some affirmative act to evade or defeat a tax, or payment of tax.” Our page on tax evasion versus tax avoidance covers that line.
Procedurally, an examiner who finds indicators must raise them with a group manager, who involves a fraud enforcement advisor. When the required affirmative acts and criminal criteria are present, the case can be referred to Criminal Investigation. Except for certain direct-referral matters, the U.S. Attorney’s Office must obtain Tax Division authorization before initiating a federal criminal tax prosecution.
The Justice Manual notes that joint investigations with revenue officers “usually evolve from a willful failure to pay tax,” which is the narrow path by which a collection case can turn into something worse.
The standards of proof differ too. Criminal cases require proof beyond a reasonable doubt. Civil fraud requires clear and convincing evidence.
File anyway, on time, and then deal with the balance.
Filing on time removes the offense that is easiest for the government to prove and cuts your penalty rate by a factor of ten. Filing late does not erase a failure-to-file violation that already occurred, but it still puts you in a far better position than continuing not to file.
If you suspect that a return was fraudulent or that your conduct could create criminal exposure, speak with a criminal tax attorney before making new statements to the IRS, filing an amended return addressing the conduct, or transferring assets. Statements made to a revenue agent are usable, and steps taken to fix a problem can themselves become affirmative acts. Our overview of IRS payment plans covers the civil options.
The gap between a collection case and a criminal case is narrower than it looks, and it is usually crossed by something the taxpayer said or did while trying to help.
