The punishment for assault runs from a few months in jail and a modest fine at the low end to 20 years or more in prison at the top. Where a specific case lands depends on three things: how the conduct is classified, whether aggravating circumstances apply, and the defendant’s prior record. Most assault cases are prosecuted in state court, and the numbers vary by jurisdiction, but the framework is consistent everywhere — the more serious the harm or intent, the harsher the sentence.
Misdemeanor Versus Felony Assault
“Assault” doesn’t mean the same thing in every state. Traditionally it meant placing someone in fear of imminent harm without physical contact, while battery meant the contact itself. Many states now fold both into a single assault statute. The specific statutory language in your jurisdiction controls what the prosecution has to prove.
However it’s defined, the charge falls into one of two tiers. Simple assault covers minor incidents: a shove, a slap, or a credible threat where no serious injury results. Aggravated or felony assault covers conduct involving weapons, serious bodily injury, or attacks on protected victims. That dividing line is where the real consequences diverge, so it matters more than any other classification question.
Federal assault law under 18 U.S.C. § 113 applies only within special maritime and territorial jurisdiction — places like military bases, national parks, and federal buildings.1Office of the Law Revision Counsel. 18 USC 113 – Assaults Within Maritime and Territorial Jurisdiction Most people charged with assault face state charges instead, but the federal penalty tiers track patterns found across state systems and are a useful reference point.
Penalties for Simple Assault
Simple assault is a misdemeanor in nearly every jurisdiction. Under federal law, simple assault carries up to six months in jail, with the maximum rising to one year if the victim is under 16. A related federal charge, assault by striking or wounding, also carries up to one year.1Office of the Law Revision Counsel. 18 USC 113 – Assaults Within Maritime and Territorial Jurisdiction State ceilings on misdemeanor assault tend to top out at one year of incarceration, with fines that vary widely by misdemeanor class.
Many states grade misdemeanors by class. A top-tier misdemeanor (often Class A or Class 1) generally allows up to a year in jail and fines reaching several thousand dollars. Lower-tier misdemeanors may cap incarceration at 30 to 90 days with smaller fines. Federal law caps individual fines for a non-fatal Class A misdemeanor at $100,000 and for a Class B or C misdemeanor at $5,000.2Office of the Law Revision Counsel. 18 USC 3571 – Sentence of Fine
Even at the misdemeanor level, the conviction creates a criminal record that shows up on background checks and can affect employment, housing, and professional licensing. First-offense jail time may be short or suspended. The record is not.
Penalties for Aggravated and Felony Assault
When an assault involves a weapon, causes serious injury, or reflects intent to inflict severe harm, it becomes a felony. The case moves from local jail time measured in months to state or federal prison measured in years.
Federal law shows the range. Assault with a dangerous weapon and intent to cause bodily harm carries up to 10 years in prison. Assault with intent to commit murder brings up to 20 years.1Office of the Law Revision Counsel. 18 USC 113 – Assaults Within Maritime and Territorial Jurisdiction For assaults on federal officers using a deadly weapon or causing bodily injury, the maximum is also 20 years.3Office of the Law Revision Counsel. 18 USC Chapter 7 – Assault State aggravated assault statutes follow comparable patterns, with many authorizing somewhere between two and 25 years depending on the degree of the offense and the weapon involved.
Fines climb steeply as well. Federal felony fines can reach $250,000 for an individual defendant.2Office of the Law Revision Counsel. 18 USC 3571 – Sentence of Fine A felony conviction also triggers lasting consequences beyond the sentence itself, including loss of firearm rights and, in most states, at least temporary loss of voting rights.
What Pushes a Sentence Higher
A handful of aggravating factors can turn a manageable charge into something life-altering. These are what prosecutors and judges focus on.
Who the Victim Was
Assaulting a law enforcement officer, firefighter, emergency medical worker, or other public servant performing official duties typically triggers an automatic charge upgrade or a mandatory minimum. Under federal law, a simple assault on a federal officer carries up to one year, but if the assault involves physical contact or intent to commit a felony, the maximum jumps to eight years. Using a deadly weapon or causing bodily injury to a federal officer raises the ceiling to 20 years.3Office of the Law Revision Counsel. 18 USC Chapter 7 – Assault Attacks on elderly or disabled victims also commonly draw enhanced charges at the state level.
Weapons and the Severity of Injury
Bringing a weapon changes the legal classification even without any intent to kill. A punch that breaks someone’s nose may be a misdemeanor; the same confrontation with a baseball bat is a felony. In federal sentencing, injury severity directly increases the offense level, with permanent or life-threatening injuries driving the longest sentences.4United States Sentencing Commission. Annotated 2025 Chapter 2 A-C
Hate Crimes
When an assault is motivated by the victim’s race, religion, national origin, gender, sexual orientation, gender identity, or disability, federal hate crime laws impose severe penalties. Under the Matthew Shepard and James Byrd Jr. Hate Crimes Prevention Act, a bias-motivated assault carries up to 10 years in prison. If the attack results in death or involves kidnapping or an attempt to kill, the penalty rises to any term of years up to life.5Office of the Law Revision Counsel. 18 USC 249 – Hate Crime Acts In federal sentencing, an additional 3-level enhancement applies when the defendant intentionally selected the victim based on a protected characteristic.6United States Sentencing Commission. Chapter Three – Adjustments
Domestic Violence
Assault against a spouse, intimate partner, or dating partner often triggers enhanced penalties and some unique consequences. Under federal law, an assault resulting in substantial bodily injury to a spouse, intimate partner, or dating partner carries up to five years.1Office of the Law Revision Counsel. 18 USC 113 – Assaults Within Maritime and Territorial Jurisdiction A misdemeanor crime of domestic violence conviction also triggers a federal ban on possessing firearms or ammunition under the Lautenberg Amendment.7Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts That ban applies whether the assault was charged as a felony or a misdemeanor, which makes these convictions unusually consequential.
Prior Record
A defendant’s history is one of the most powerful sentencing factors. Under the federal guidelines, prior convictions generate criminal history points that place the defendant in a higher sentencing category. Each prior sentence of more than a year adds 3 points. A defendant classified as a “career offender” because of two or more prior felony convictions for crimes of violence automatically falls into the highest criminal history category, which can more than double the guideline range.8United States Sentencing Commission. Annotated 2025 Chapter 4 State systems follow the same logic: repeat offenders face dramatically longer sentences than first-time defendants charged with the same conduct.
Consequences Beyond the Sentence
The formal sentence is only part of the picture. The lasting damage from a conviction often comes from consequences that aren’t written into the sentencing order.
Firearm Restrictions
Federal law prohibits anyone convicted of a crime punishable by more than one year of imprisonment from possessing firearms or ammunition. That covers virtually every felony assault conviction. For misdemeanor domestic violence convictions, the Lautenberg Amendment imposes the same ban regardless of the sentence imposed.7Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts These are lifetime prohibitions in most cases, and violating them is itself a federal felony.
Voting Rights
A felony assault conviction triggers the loss of voting rights in nearly every state, though the duration varies. Only two states allow voting while incarcerated for a felony. In roughly a dozen states, rights are restored automatically upon release from prison. Many others require completion of parole and probation before restoring eligibility, and a handful require an individual petition to the government.
Employment and Licensing
Assault convictions, including misdemeanors, appear on standard background checks. “Ban the box” laws in many states delay when employers can ask about criminal history, but the conviction still surfaces once a conditional offer is made. Fields that require professional licensing — healthcare, education, law enforcement, accounting — routinely review holders’ criminal records, and a conviction can trigger disciplinary proceedings that lead to suspension or revocation.
Immigration
For non-citizens, an assault conviction can be devastating. Aggravated assaults and assaults involving dangerous weapons are generally treated as crimes involving moral turpitude, which can trigger deportation or make a person inadmissible for future entry. A crime of violence with a sentence of five years or more qualifies as an aggravated felony under immigration law, which carries mandatory removal with almost no relief available.9United States Department of Justice. Criminal Resource Manual 1934 – Appendix D – Grounds for Judicial Deportation Even a misdemeanor assault can complicate visa renewals, green card applications, and naturalization.
Defenses That Can Reduce or Eliminate the Penalty
Not every assault charge produces a conviction. Several well-established defenses can reduce the charge or eliminate liability.
Self-defense is the most commonly raised. The defendant generally has to show a reasonable belief in an imminent threat of physical harm and a proportional response. The force has to match the threat — you can’t answer a shove with a knife. Once the threat ends, the right to use force ends with it. Some states impose a duty to retreat before using force; others follow “stand your ground” laws that remove that obligation. Defense of others applies the same proportionality rules when you step in to protect someone else.
Imperfect self-defense applies when the defendant genuinely believed they were in danger but that belief wasn’t objectively reasonable. It doesn’t produce an acquittal, but it can reduce a felony charge to a lesser offense. Consent is a narrow defense that sometimes applies in mutual combat, though most jurisdictions limit how far consent goes, particularly when serious injury results.
Restitution, Probation, and Civil Liability
Courts regularly order defendants to pay restitution covering the victim’s direct financial losses. Under federal law, restitution is mandatory for crimes of violence and must include medical and psychological care, physical rehabilitation, and income lost because of the offense. The court can also order reimbursement for child care, transportation, and other expenses the victim incurred during the investigation and prosecution.10Office of the Law Revision Counsel. 18 USC 3663A – Mandatory Restitution to Victims of Certain Crimes Restitution is separate from any fine the court imposes. Failing to pay can trigger additional penalties or a supervised release violation.
For lower-level convictions, courts often impose alternatives to incarceration. Probation requires regular check-ins with a supervising officer and compliance with conditions such as curfews, travel restrictions, and no-contact orders with the victim. Anger management programs and community service are standard conditions. Violating any term gives the court authority to revoke the alternative and impose the original jail or prison time.
A criminal case is not the only exposure. Victims can file a separate civil lawsuit, and the two cases run independently. The civil case uses a lower burden of proof: the victim only needs to show it’s more likely than not that the defendant caused the harm. That means someone acquitted in criminal court can still lose a civil case over the same incident. The victim can recover compensatory damages for medical bills, lost wages, and pain and suffering, as well as punitive damages when the conduct was particularly egregious. Any money awarded goes to the victim rather than to the government.
