The penalty for obstruction of justice runs from a few months in jail for a misdemeanor like lying to a local officer to life in prison or the death penalty when the obstruction involves killing a juror or witness. Most federal obstruction offenses carry maximum sentences between five and thirty years, and the specific statute charged does more to shape the outcome than almost anything else. State penalties vary widely but follow the same logic: the greater the threat to a person or a proceeding, the harsher the punishment.
Federal Maximum Sentences by Offense
Federal obstruction charges sit in Chapter 73 of Title 18 of the United States Code, which contains more than 20 separate statutes.1Office of the Law Revision Counsel. 18 U.S. Code Chapter 73 – Obstruction of Justice Each one defines a different type of conduct and sets its own ceiling. Which statute a prosecutor charges is the first thing to look at.
Threatening or Harming Jurors and Court Officers
Under 18 U.S.C. 1503, intimidating, threatening, or bribing a juror or court officer carries up to 10 years. If the offense involves an attempted killing, or if a Class A or Class B felony was charged in the case involving a petit juror, the maximum rises to 20 years. If the defendant actually kills a juror or court officer, the penalty matches the federal murder statute, which allows life imprisonment or the death penalty.2Office of the Law Revision Counsel. 18 USC 15033Office of the Law Revision Counsel. 18 U.S. Code 1111 – Murder
Witness Tampering
Penalties under 18 U.S.C. 1512 climb sharply with the method used. Harassing someone to discourage them from testifying or reporting a crime carries up to three years. Threatening physical force to influence testimony raises the maximum to 20 years. Using physical force or attempting to kill a witness to prevent testimony can bring up to 30 years. Killing a witness triggers the federal murder penalties, meaning life imprisonment is on the table.4Office of the Law Revision Counsel. 18 USC 1512 – Tampering With a Witness, Victim, or an Informant
Retaliation Against Witnesses
Section 1513 covers conduct that happens after someone has cooperated. Causing bodily injury or property damage in retaliation for testifying, or threatening to do so, carries up to 20 years. An attempted retaliatory killing allows up to 30 years, and a completed killing is punished under the federal murder statute.5Office of the Law Revision Counsel. 18 U.S. Code 1513
Destroying Records or Evidence
Section 1519 makes it a crime to knowingly destroy, alter, or falsify any record, document, or tangible object with intent to obstruct a federal investigation or bankruptcy proceeding. The maximum is 20 years. The statute is unusually broad: it reaches paper files, electronic records, and any physical object, and it does not require that a formal proceeding already be underway.6Office of the Law Revision Counsel. 18 USC 1519
Obstruction of Government Proceedings
Interfering with proceedings before a federal department, agency, or congressional committee is covered by 18 U.S.C. 1505. The standard maximum is five years in prison plus a fine. When the obstruction involves domestic or international terrorism, the ceiling rises to eight years.7Office of the Law Revision Counsel. 18 USC 1505
False Statements to Federal Investigators
Lying to a federal agent is a separate crime under 18 U.S.C. 1001, even without an oath. Knowingly making a materially false statement to the executive, legislative, or judicial branch carries up to five years. The maximum rises to eight years when the false statement involves terrorism or certain offenses against minors.8Office of the Law Revision Counsel. 18 USC 1001
Obstructing a Criminal Investigation
Under 18 U.S.C. 1510, using bribery to prevent someone from sharing information about a federal crime with investigators carries up to five years.9Office of the Law Revision Counsel. 18 U.S. Code 1510
Conspiracy
Two or more people who agree to commit any of these offenses and take a concrete step toward it can be charged with conspiracy under 18 U.S.C. 371. The general conspiracy statute itself carries up to five years.10Office of the Law Revision Counsel. 18 U.S. Code 371
What Sentences Look Like in Practice
The numbers above are statutory ceilings, not what most defendants actually receive. Federal judges work from the sentencing guidelines, which assign a base offense level and adjust from there. For obstruction, the base level is 14, which translates to roughly 15 to 21 months in prison for a first-time offender with no criminal history.11United States Sentencing Commission. Annotated 2025 Chapter 2 E-K12United States Sentencing Commission. Sentencing Table – 2024 Guidelines Manual
Several enhancements can push that number up:
- Causing or threatening physical injury or property damage adds 8 levels.
- Substantially interfering with the administration of justice adds 3 levels.
- Destroying a large number of records, targeting especially important documents, or otherwise extensive obstruction adds 2 levels.
These enhancements stack. The 8-level bump alone can more than double the recommended prison time.11United States Sentencing Commission. Annotated 2025 Chapter 2 E-K
Obstruction can also lengthen a sentence for a different crime. If you’re convicted of an offense and you obstructed the investigation or prosecution of that same offense, the guidelines add 2 levels to the underlying conviction. Judges apply this even for conduct like lying during a presentencing interview or destroying evidence tied to your own case.13United States Sentencing Commission. Annotated 2025 Chapter 3
State Penalties
Every state criminalizes some form of obstruction, but the labels and penalties differ. Serious conduct like witness tampering and evidence destruction is usually a felony, with prison sentences commonly running from one to ten years and fines reaching $25,000 or more. Less severe conduct, such as lying to a police officer or refusing to comply with a lawful order, may be a misdemeanor carrying a few months to a year in jail.
What counts as a misdemeanor in one state can be a felony in the next. Some states break obstruction into separate statutes for resisting arrest, hindering prosecution, and tampering with evidence; others fold most of it into a single statute. The specific statute in the charging state determines the range.
How Long Prosecutors Have to Charge You
Federal prosecutors generally have five years from the date of the offense to bring obstruction charges, the standard limitations period under 18 U.S.C. 3282 for non-capital federal offenses.14United States Department of Justice. Criminal Resource Manual 650 One major exception: if the obstruction involved a killing, there is no time limit at all, because capital offenses carry no statute of limitations.
State deadlines vary. Most fall in the three-to-six-year range for felony obstruction, and some states pause the clock if the defendant leaves the state.
Conduct That Is Not Obstruction
Plenty of behavior that frustrates investigators is not a crime. Staying silent when questioned by police is not obstruction; the Fifth Amendment protects the refusal to answer, and invoking it cannot be held against you. Hiring a defense attorney, telling someone else to hire one, and challenging a subpoena through legal channels are all protected.
The line is corrupt intent. Telling a friend not to cooperate is not the same as telling them to lie. Deleting personal files is not the same as shredding documents you know a grand jury has demanded. Federal obstruction statutes almost universally require proof that the defendant acted corruptly or with specific intent to impede a proceeding. Without that element, there’s no crime, which is why the most common defense is challenging intent, especially when the conduct has an innocent explanation.
Consequences That Outlast the Sentence
A conviction creates problems that continue after the prison term and fine are done.
- Licensing boards in law, finance, medicine, and education often treat obstruction as a crime of dishonesty and can deny, suspend, or revoke a license. Financial regulators are particularly aggressive, and a conviction involving dishonesty can permanently bar someone from working at a federally insured bank.
- For noncitizens, an obstruction conviction can trigger deportation. Immigration law treats crimes involving moral turpitude as grounds for removal, and obstruction frequently qualifies.
- Any felony conviction, including felony obstruction, makes it illegal under federal law to possess a firearm.
- Obstruction convictions appear on background checks, and employers in trust-based positions treat the offense as especially disqualifying.
- In most states, a felony conviction causes at least temporary loss of voting rights. Restoration processes vary.
These consequences stack. A financial professional convicted of obstruction during a fraud investigation could lose a license, a current job, and the ability to work in the industry again, on top of whatever sentence the court imposes.
