Different Degrees of Assault and Their Penalties

The degrees of assault and their penalties fall into three broad tiers that most states share, even when the labels differ. At the bottom is simple assault (called third-degree in some states), a misdemeanor generally capped at six months to a year in jail. In the middle is second-degree assault, which can be a high-level misdemeanor or a felony carrying roughly two to seven years in prison. At the top is aggravated assault (first-degree in degree-based states), a felony with prison exposure that commonly runs from five to twenty-five years. Three factors drive where a given case lands: what the accused intended, whether a weapon was involved, and how badly the victim was hurt.

How States Label the Tiers

The Model Penal Code, which has shaped criminal statutes across the country, uses just two categories: simple assault (a misdemeanor) and aggravated assault (a felony).¹ Many states adopted that two-tier approach. Others split the offense into numbered degrees, where first-degree is the most serious and third-degree is the least. A handful use hybrid systems that combine degree labels with named offenses like “assault with a deadly weapon.”

The practical point is that “second-degree assault” in one state may cover conduct that another state calls something else entirely. The specific elements and the exact penalty range depend on the state statute that applies to the case. What follows describes the general principles that most systems share.

Aggravated Assault (First-Degree)

The most serious tier covers intentionally causing or attempting to cause serious bodily injury, or using a deadly weapon to injure someone. Under the Model Penal Code, the felony grade turns on whether the defendant caused serious bodily injury with extreme indifference to human life (the more serious felony) or used a deadly weapon to cause or attempt bodily injury (a slightly less serious felony).¹

“Serious bodily injury” has a specific legal meaning. Under federal law, it includes any injury involving a substantial risk of death, extreme physical pain, long-lasting and obvious disfigurement, or extended loss of function of a body part, organ, or mental faculty.² Most state definitions track this language closely. A broken jaw that heals in six weeks might not qualify; a skull fracture causing permanent cognitive problems almost certainly would. Cases often turn on whether the prosecution can prove the injuries crossed that threshold.

Penalties vary by state but commonly range from five to twenty-five years in prison. Some states impose mandatory minimums for certain aggravated assaults, particularly when the victim is a child or when a firearm was used.

Second-Degree Assault

In states that use a degree system, second-degree assault covers conduct more serious than a minor scuffle but less severe than the worst aggravated assaults. The charge usually applies when someone intentionally causes bodily injury that falls short of “serious” bodily injury, or when someone recklessly causes injury using a weapon or dangerous object.

A common example: someone swings a heavy object during a fight and breaks the other person’s arm. The injury is real and required medical treatment, but it isn’t life-threatening or permanently disabling. That gap between “hurt” and “seriously hurt” is where second-degree assault lives. Some states also use this charge when someone injures a person while committing another crime or when the victim belongs to a protected category like an on-duty emergency responder.

Depending on the jurisdiction and the specific facts, second-degree assault can be charged as a felony or as a high-level misdemeanor. Felony classifications are more common when a weapon is involved or the victim needed significant medical care. Prison sentences for felony second-degree assault typically run from two to seven years, though the ceiling is higher in some states.

Simple Assault (Third-Degree)

The lowest tier covers the broadest range of conduct. Under the Model Penal Code, simple assault includes attempting to cause bodily injury, recklessly causing bodily injury, or using physical threats to put someone in fear of imminent serious harm.¹ The resulting injuries are minor or nonexistent: bruises, scrapes, or just the fear of being hit.

Simple assault is generally a misdemeanor. Under federal law, it carries a maximum of six months in jail. If the victim is under 16, the maximum increases to one year.³ State penalties follow a similar pattern, with most capping jail time at six months to a year for a standard simple assault conviction. Federal law also allows a fine of up to $100,000 for a Class A misdemeanor.⁴

Don’t let the word “simple” make this sound trivial. A misdemeanor assault still produces a permanent criminal record, and the collateral effects can follow you for years.

Federal Assault Tiers Under 18 U.S.C. § 113

Federal assault charges apply within federal jurisdiction: military bases, national parks, federal buildings, and similar areas. Instead of a degree system, the federal statute lays out eight distinct offense tiers with their own maximum sentences:

Assault with intent to commit murder: up to 20 years in prison
Assault with intent to commit a felony (other than murder): up to 10 years
Assault with a dangerous weapon, intending bodily harm: up to 10 years
Assault resulting in serious bodily injury: up to 10 years
Strangulation or suffocation of a spouse, intimate partner, or dating partner: up to 10 years
Assault causing substantial bodily injury to a spouse, intimate partner, dating partner, or child under 16: up to 5 years
Assault by striking, beating, or wounding: up to 1 year
Simple assault: up to 6 months (up to 1 year if the victim is under 16)

Each category carries a fine in addition to imprisonment.³ The federal ladder illustrates how legislatures structure assault severity across the board: by the weapon used, the intent behind the act, and the harm that resulted.

What Pushes an Assault Into a Higher Penalty

Several circumstances can move an assault charge into a higher tier or trigger enhanced penalties beyond the standard range. These aggravating factors are where prison sentences get long.

Use of a Weapon

A weapon is the single most common reason an assault charge jumps from misdemeanor to felony territory. Federal sentencing guidelines treat the presence of a dangerous weapon as a defining feature of aggravated assault.⁵ The legal definition is broad. It covers firearms and knives, but also everyday objects used in a way capable of causing serious harm. Courts have classified baseball bats, vehicles, bottles, and even shod feet as dangerous weapons depending on how they were used.

The distinction between a “dangerous weapon” and a “deadly weapon” affects sentencing exposure. Under federal law, assault with a dangerous weapon carries up to 10 years in prison, compared to a maximum of one year for assault by striking or wounding without a weapon.³

Who the Victim Is

Assaulting certain categories of people carries steeper penalties in most jurisdictions. Protected groups typically include law enforcement officers, firefighters, paramedics, and healthcare workers performing their duties. Under federal law, even a simple assault against a federal officer is punishable by up to one year in prison. If the assault involves physical contact or intent to commit another felony, the maximum jumps to eight years. Using a deadly weapon or inflicting bodily injury pushes it to 20 years.⁶

Assaults on vulnerable people also draw harsher treatment. The federal statute doubles the maximum jail time for simple assault against a child under 16, from six months to one year.³ State laws often go further, creating separate offenses for assaulting children, elderly individuals, or people with disabilities, sometimes with mandatory minimum sentences.

Bias Motivation

An assault motivated by the victim’s race, color, religion, national origin, gender, sexual orientation, gender identity, or disability can be prosecuted as a federal hate crime. Under 18 U.S.C. § 249, conviction carries up to 10 years in prison. If the assault results in death or involves kidnapping or an attempt to kill, the sentence can reach life imprisonment.⁷ Most states have parallel hate crime statutes that enhance penalties for bias-motivated assaults.

Domestic Context

When an assault occurs between spouses, intimate partners, dating partners, or household members, penalties often escalate. Under federal law, assault causing substantial bodily injury to a spouse, intimate partner, or dating partner is punishable by up to five years in prison, and strangulation or suffocation of such a person carries up to 10 years.³ Many states escalate domestic assault charges further on repeat offenses, sometimes elevating what would be a misdemeanor to a felony on a second or third conviction.

Penalties Beyond the Sentence

Jail time and fines are only part of what a conviction costs. Assault convictions carry consequences that reach well outside the courtroom.

Restitution to the Victim

A person convicted of assault may be ordered to pay restitution directly to the victim. Under federal law, restitution is mandatory for crimes involving bodily injury. The court must order the defendant to pay for the victim’s medical and rehabilitation costs, lost income, and transportation expenses related to medical care.⁸ Most states have similar statutes. Unlike a fine paid to the government, restitution goes to the victim and can cover everything from emergency room bills to physical therapy to psychiatric treatment.

Firearm Prohibitions

Any felony assault conviction triggers a lifetime federal ban on possessing firearms or ammunition. For misdemeanors, the restriction is narrower but still significant: a misdemeanor domestic violence conviction prohibits firearm possession if the offense involved the use or attempted use of physical force, or the threatened use of a deadly weapon, against a spouse, partner, co-parent, or household member. Violating this federal prohibition is itself a crime punishable by up to 15 years in prison.⁹

The conviction does not need to be labeled “domestic violence” to trigger the ban. Any misdemeanor meeting the statutory criteria qualifies. The prohibition can be lifted if the conviction is expunged or pardoned and the person’s civil rights (voting, jury service, holding office) are restored, but only if the expungement or pardon does not explicitly bar firearm possession.⁹

Employment, Licensing, and Immigration

An assault conviction, even a misdemeanor, shows up on background checks and can disqualify you from jobs in healthcare, education, law enforcement, childcare, and any field requiring a professional license. Many licensing boards have discretion to deny or revoke credentials based on violent offense convictions. For non-citizens, an assault conviction can trigger deportation or bar adjustment of immigration status, particularly if the offense qualifies as a “crime involving moral turpitude” or an aggravated felony under immigration law.

Expungement Limits

Whether you can eventually clear an assault conviction from your record depends on the state and the severity of the charge. Most states prohibit expungement of violent felony convictions. For misdemeanor assault, eligibility rules vary widely. Some states allow expungement after a waiting period of two to five years with no subsequent offenses; others exclude domestic violence misdemeanors entirely. Legal and administrative fees typically run from a few hundred to a few thousand dollars.

Civil Lawsuits

Criminal charges and civil lawsuits run on parallel tracks. Even if criminal charges are dropped or result in acquittal, the victim can file a civil lawsuit seeking money damages. The burden of proof in civil court is lower: preponderance of the evidence rather than beyond a reasonable doubt. Compensatory damages typically cover medical expenses, lost wages and reduced earning capacity, and pain and suffering. If the conduct was especially outrageous, punitive damages may be added on top.
