How long you go to jail for terroristic threats runs from up to a year in county jail for a misdemeanor to 20 years or more in federal prison for the most serious charges. The spread is that wide because the same label covers an angry text to an ex and a bomb threat called into an airport, and prosecutors treat those very differently. What was said, how it was sent, who was targeted, and whether anyone had to evacuate all push the sentence up or down.
State Sentences by Charge Level
Most terroristic threat cases are prosecuted in state court, and each state writes its own statute. The charges generally sort into two tiers.
Misdemeanor Threats
A threat against an individual with no aggravating factors is usually a misdemeanor. The maximum is typically up to one year in a county jail, plus fines. First-time offenders charged at this level often end up with probation, community service, or a suspended sentence rather than actual jail time, especially if the threat was impulsive and nobody was hurt.
Felony Threats
The charge jumps to a felony when the threat targets a school, government building, public utility, or large gathering, when a weapon is involved, or when the threat triggers an evacuation or major emergency response. Felony ranges vary a lot by state:
- Basic felony threats: up to three to five years in state prison in many states.
- Threats against schools, public buildings, or involving specific weapons: often five to ten years.
- The most serious state charges, including threats of mass destruction or mass killing classified as domestic terrorism under state law: 20 to 30 years.
In states that classify a terroristic threat conviction as a violent felony, the person may have to serve up to 85 percent of the imposed sentence before becoming eligible for release.
Restitution often comes on top of the prison term. When a threat sets off a police and fire response, a building evacuation, or a business shutdown, many states require the defendant to reimburse those costs. Emergency responses to bomb threats at schools and office buildings can run into tens of thousands of dollars.
Federal Sentences by Statute
A threat becomes a federal case when it crosses state lines, targets federal officials or property, involves air travel, or travels over interstate communication channels like the internet or phone. Several federal statutes can apply, and the ceilings differ sharply.
Interstate Threats, 18 U.S.C. § 875
This is the main federal threat statute. It reaches almost anything sent by phone, email, text, or social media. The ceilings depend on what the threat was for:
- General threat to kidnap or injure someone: up to five years.
- Threat to kidnap or injure with intent to extort money or something of value: up to 20 years.
- Threat to damage property or reputation with intent to extort: up to two years.
The leap from five years to 20 turns entirely on whether the threat was paired with a demand. An angry threat and the same threat used as leverage sit in different sentencing worlds.
Bomb Threats, 18 U.S.C. § 844(e)
Threatening to damage or destroy a building, vehicle, or other property with fire or explosives through any means of interstate commerce carries up to 10 years. Knowingly conveying false information about a bombing attempt carries the same ceiling. This is the statute behind the classic phoned-in bomb threat to a school or courthouse.
Threats Against Federal Officials, 18 U.S.C. § 115
Threatening a federal judge, member of Congress, or other federal official or their family carries up to 10 years. The ceiling drops to six years when the underlying conduct is an assault rather than more serious violence.
Threats Against the President, 18 U.S.C. § 871
Threatening to kill, kidnap, or inflict bodily harm on the President, Vice President, President-elect, or anyone in the line of succession carries up to five years. The Secret Service investigates these cases aggressively, and offhand social media posts have led to federal prosecution.
Hoax Threats, 18 U.S.C. § 1038
Filing a false report or conveying misleading information meant to make people believe a terrorist attack or violent crime is underway is a separate federal offense. The base ceiling is five years. If the hoax causes serious bodily injury, the maximum jumps to 20 years. If someone dies as a result, the sentence can reach life.
Weapons of Mass Destruction Threats, 18 U.S.C. § 2332a
Threatening to use a chemical, biological, radiological, or nuclear weapon is among the most severely punished threat offenses in federal law. Prosecution under this statute can mean decades in prison, especially when the target is a government facility or large civilian population and the conduct crosses national boundaries.
What Moves a Sentence Up or Down
Statutory maximums are ceilings, not predictions. Within the range, judges weigh several factors:
- Criminal history. Prior convictions, especially for violent crimes or similar threats, consistently push sentences higher. A clean record leaves far more room to argue for leniency.
- Specificity and credibility. A detailed plan naming a target, date, and method is treated very differently from a vague outburst.
- Actual disruption. A threat that triggered an evacuation, school lockdown, or bomb squad response draws a longer sentence than one that stayed between the sender and the recipient.
- Weapons. Brandishing or possessing a weapon while making the threat almost always leads to enhanced charges or added time.
- Acceptance of responsibility. Pleading guilty and showing genuine remorse typically reduces the sentence. Federal sentencing guidelines include a specific reduction for it.
- Restitution. Expensive emergency responses factor into both the sentence and the order to repay those costs.
A “Terroristic Threat” Charge Is Not a Terrorism Charge
This confuses people constantly, and it matters for sentencing. When a state charges someone with making a “terroristic threat,” the charge is a conventional threat crime with an alarming name. It does not mean the person is being prosecuted as a terrorist. There is no standalone federal crime of “domestic terrorism” that prosecutors can charge on its own. State terroristic threat statutes carry penalties in the range of other threat and intimidation offenses. Federal terrorism statutes, such as 18 U.S.C. § 2332b for conduct transcending national boundaries, are a different animal, with far steeper penalties.
When Speech Is Protected
Not every frightening statement is a crime, and that affects whether anyone goes to jail at all. The First Amendment protects political hyperbole, dark humor, and heated rhetoric. Only “true threats,” statements made with the purpose of placing someone in fear of bodily harm or death, fall outside that protection.
In 2023, the Supreme Court decided Counterman v. Colorado and raised the bar for conviction. Prosecutors must now prove the defendant had some subjective awareness that their words could be taken as threatening. Showing that a reasonable listener would feel threatened is not enough; the government has to show the speaker consciously disregarded a substantial risk that the words would be heard as a threat of violence. The Court set recklessness as the minimum mental state. That requirement gives defense attorneys real room to challenge charges when the statement was ambiguous, made in an obviously non-literal context, or lost in the back-and-forth of an online argument.
Juveniles and School Threats
School threats are the fastest-growing category of terroristic threat cases, and many of the people making them are minors. Most juveniles are initially handled in juvenile court, where the focus leans toward rehabilitation. Many schools now use threat assessment teams that evaluate concerning behavior and try to intervene before law enforcement gets involved.
Serious or repeated threats can still push a case into adult court. Judges weigh the seriousness of the threat, whether it was premeditated, the juvenile’s prior record and maturity, and the likelihood of rehabilitation. Some states require adult prosecution for juveniles over a certain age who violate weapon-free school zone laws. A juvenile tried as an adult faces the same penalties an adult would, including years in prison for a felony.
What a Conviction Costs Beyond Prison
Prison time is only part of the picture. A felony terroristic threat conviction carries lasting consequences.
Federal law bars anyone convicted of a crime punishable by more than one year in prison from possessing firearms or ammunition. A felony threat conviction triggers that ban permanently, and violating it is a separate federal crime.
For non-citizens, a conviction for a crime involving moral turpitude or any terrorism-related activity can trigger deportation and mandatory detention. A single conviction within five years of admission can make a green card holder deportable if the offense carries a potential sentence of one year or more.
On the employment side, a felony shows up on background checks and can disqualify someone from jobs in education, healthcare, law enforcement, government, and any field requiring a professional license. Licensing boards in many states have authority to suspend or revoke credentials after a criminal conviction.
Court costs add a financial layer. Mandatory fees on felony convictions typically run several hundred dollars, on top of fines, restitution for emergency response costs, and attorney fees. The total hit routinely reaches into the thousands before accounting for lost income during incarceration.
