The different types of crimes fall into two overlapping maps. One sorts offenses by severity: felonies, misdemeanors, and infractions. The other sorts them by what the offense targets: people, property, money, drugs, or computer systems. Penalties range from a small fine with no jail time for an infraction up to life imprisonment or the death penalty for the most serious felonies, with the exact punishment turning on both the category and the specific facts of what happened.
How Crimes Are Classified by Severity
Every criminal offense sits in one of three tiers based on how much the law punishes it. The tier matters for more than prison time. It also shapes long-term consequences like firearm rights, jury service, and professional licensing.
Felonies
Felonies are the most serious tier. Under federal law, any offense carrying more than one year in prison is a felony, and the category breaks further into five classes based on the maximum possible sentence. A Class A felony, the most severe, carries life imprisonment or the death penalty. A Class E felony, the least serious felony, carries between one and five years.1Office of the Law Revision Counsel. 18 U.S. Code 3559 – Sentencing Classification of Offenses Federal fines for felonies can reach $250,000 for individuals and $500,000 for organizations, though a judge can impose up to twice the financial gain or loss caused by the crime if that amount is higher.2Office of the Law Revision Counsel. 18 U.S. Code 3571 – Sentence of Fine
The real weight of a felony conviction often shows up after the prison sentence ends. People with felony records commonly lose the right to possess firearms, serve on a jury, or hold certain professional licenses, and these restrictions frequently apply regardless of how much time has passed since the conviction.3National Inventory of Collateral Consequences of Criminal Conviction.

Misdemeanors
Misdemeanors sit in the middle. These offenses carry jail terms of one year or less, typically served in a local or county facility rather than a state prison.4National Conference of State Legislatures. Misdemeanor Sentencing Trends Federal law divides misdemeanors into three classes: Class A (up to one year), Class B (up to six months), and Class C (up to thirty days).1Office of the Law Revision Counsel. 18 U.S. Code 3559 – Sentencing Classification of Offenses Fines run from a few hundred dollars for minor charges up to $100,000 for a federal Class A misdemeanor.2Office of the Law Revision Counsel. 18 U.S. Code 3571 – Sentence of Fine A misdemeanor still creates a criminal record that shows up on background checks for employment and housing.
Infractions
Infractions are the least serious tier and cover offenses like minor traffic violations or littering. Under federal law, an infraction carries five days or less of jail time, or no jail time at all, with fines capped at $5,000.1Office of the Law Revision Counsel. 18 U.S. Code 3559 – Sentencing Classification of Offenses2Office of the Law Revision Counsel. 18 U.S. Code 3571 – Sentence of Fine Most can be resolved by paying the fine without appearing in court, and they rarely leave a permanent criminal record.
How Federal Sentencing Guidelines Fit In
For federal crimes, judges don’t simply pick a sentence from thin air. The U.S. Sentencing Commission maintains a framework that combines two factors: the seriousness of the offense (measured on a scale of 1 to 43 offense levels) and the defendant’s criminal history (sorted into six categories, with Category I the least serious). Where those two numbers intersect produces a recommended prison range in months. A first-time offender convicted of a mid-level offense might face 30 to 37 months, while the same offense committed by someone with an extensive record could carry 63 to 78 months. Judges can depart from the range, but it anchors most federal sentences.
Crimes Against Persons
Offenses directed at individuals involve acts that cause physical injury, psychological harm, or death. The legal system treats these as the most serious category because they directly threaten human life and safety.
Homicide
Homicide involves one person unlawfully causing the death of another. The legal system distinguishes between degrees based on the killer’s state of mind. A premeditated killing carries the harshest punishment. Under federal sentencing guidelines, premeditated murder warrants life imprisonment when the death penalty is not imposed.5United States Sentencing Commission. Amendment 663 Killings that happen in the heat of the moment or through reckless behavior typically fall into lower categories with shorter sentences, though “shorter” here still means decades in prison.
Assault and Battery
Assault is the act of intentionally putting someone in fear of imminent physical harm. Battery occurs when harmful or unwanted physical contact actually happens. Under federal law, simple assault carries up to six months in jail, or up to one year if the victim is under sixteen.6Office of the Law Revision Counsel. 18 U.S. Code 113 – Assaults Within Maritime and Territorial Jurisdiction Penalties escalate sharply when a weapon is involved or the victim suffers serious injury. Assaulting a federal officer with a dangerous weapon can bring up to ten years, and assault causing serious bodily injury through scalding or caustic substances can reach twenty years.7United States Sentencing Commission. Amendment 614
Kidnapping
Kidnapping involves seizing or confining another person against their will through force or deception. Federal law punishes kidnapping with any term of years up to life, and the penalty rises to death or life imprisonment if anyone dies during the crime. When the victim is a child under eighteen and the kidnapper is not a parent or close relative, the sentence must include at least twenty years in prison.8Office of the Law Revision Counsel. 18 USC 1201 – Kidnapping
Robbery
Robbery is taking property from another person through force or the threat of force. Because the crime involves direct confrontation with the victim, the law treats it as a violent offense rather than a simple theft. Federal data shows that the average prison sentence for robbery is about nine years, jumping to roughly thirteen and a half years when a firearm is involved. Factors that increase sentences include brandishing a weapon, injuring the victim, abducting or restraining someone, and carjacking.9United States Sentencing Commission. Robbery Offenses
Hate Crime Enhancements
When a crime is motivated by bias against a victim’s race, religion, national origin, gender, sexual orientation, gender identity, or disability, federal law allows for enhanced penalties. Under the Matthew Shepard and James Byrd Jr. Hate Crimes Prevention Act, a bias-motivated assault can bring up to ten years in prison. If the attack results in death, or involves kidnapping or an attempt to kill, the sentence can extend to life imprisonment.10Office of the Law Revision Counsel. 18 USC 249 – Hate Crime Acts Federal sentencing guidelines also add three offense levels to any crime where the court finds the defendant intentionally targeted a victim because of a protected characteristic.11United States Sentencing Commission. 2018 Chapter 3
Crimes Against Property
Property crimes involve the unauthorized taking, destruction, or interference with someone else’s belongings or real estate. Penalties scale based on the value of the property involved, whether force was used, and the level of danger the act created.
Theft and Larceny
Theft covers taking another person’s property with the intent to keep it permanently. Most jurisdictions draw a line between petty theft and grand theft based on the dollar value of what was stolen. The threshold that elevates a theft from a misdemeanor to a felony ranges from roughly $1,000 to $2,500 depending on where the offense occurs. Sentences scale accordingly, from a few months in jail for a minor shoplifting charge to several years in prison for high-value theft.
Large-scale, coordinated theft operations have become a distinct enforcement priority. Organized retail theft involves criminal groups that steal large quantities of merchandise from multiple stores and resell the goods through online marketplaces, flea markets, or fencing operations. When these operations reach federal prosecution thresholds, the FBI investigates in partnership with local law enforcement and the private sector, and reported cases have involved stolen merchandise valued in the hundreds of thousands to millions of dollars.12Federal Bureau of Investigation. Organized Retail Theft
Burglary
Burglary is entering a building or structure without permission with the intent to commit a crime inside. The crime is complete once the unauthorized entry happens with criminal intent, even if the person never actually steals anything. Penalties increase when the building is someone’s home rather than a commercial space, when the entry happens at night, or when the burglar uses force or weapons.
Motor Vehicle Theft
Stealing a car, truck, or motorcycle is tracked separately from other theft because of how frequently it occurs. Penalties vary widely by jurisdiction but commonly range from a year or two for a single stolen vehicle up to ten or more years for repeat offenders or high-value thefts. Returning the vehicle after the fact does not erase criminal liability, and courts routinely order restitution payments to the owner on top of any prison sentence.
Arson
Arson is the deliberate burning of a building, vehicle, or other property. Federal law treats arson as a serious felony carrying a mandatory minimum of five years and a maximum of twenty years in prison. If someone is injured as a result, the sentence range jumps to seven to forty years. If anyone dies, the penalty can include life imprisonment or the death penalty.13Office of the Law Revision Counsel. 18 USC 844 – Penalties
White-Collar and Financial Offenses
White-collar crimes are non-violent offenses committed through deception for financial gain. They typically involve complex paper trails, and investigators have to reconstruct financial records to prove that the defendant intended to deceive rather than simply made accounting mistakes.
Embezzlement
Embezzlement occurs when someone in a position of trust, such as an employee or financial officer, diverts money or property entrusted to them. Penalties depend on who the victim is and how much was taken. A bank officer who embezzles funds can face up to thirty years in prison and a fine of up to $1,000,000 under federal law. If the amount taken is $1,000 or less, the maximum drops to one year.14Office of the Law Revision Counsel. 18 USC 656 – Theft, Embezzlement, or Misapplication by Bank Officer or Employee Separate federal statutes cover embezzlement from government programs, pension funds, and other specific sources, each with its own penalty range.
Money Laundering
Money laundering is the process of making illegally obtained funds appear legitimate by moving them through a series of financial transactions. Federal law targets anyone who knowingly conducts a financial transaction involving the proceeds of criminal activity. A conviction carries up to twenty years in prison and a fine of $500,000 or twice the value of the property involved, whichever is greater.15Office of the Law Revision Counsel. 18 U.S. Code 1956 – Laundering of Monetary Instruments
Fraud
Fraud covers a broad range of schemes that use false statements or misrepresentations to separate people from their money or property. Wire fraud, one of the most commonly charged federal offenses, involves using electronic communications to carry out a fraudulent scheme. It carries up to twenty years in prison, and that maximum jumps to thirty years and a $1,000,000 fine when the fraud affects a financial institution or exploits a presidentially declared disaster.16Office of the Law Revision Counsel. 18 USC 1343 – Fraud by Wire, Radio, or Television Other common federal fraud charges include securities fraud, insurance fraud, and healthcare fraud, each governed by its own statute.
Identity Theft
Identity theft involves using someone else’s personal information without permission to commit fraud or other crimes. Federal law treats this especially harshly when it occurs alongside another felony. Aggravated identity theft carries a mandatory two-year prison sentence that must be served on top of whatever sentence the underlying crime carries, not at the same time. If the identity theft is connected to terrorism, the mandatory add-on rises to five years. Courts cannot place someone convicted of aggravated identity theft on probation, and judges are prohibited from shortening the sentence for the underlying crime to compensate for the mandatory add-on.17Office of the Law Revision Counsel. 18 USC 1028A – Aggravated Identity Theft
Drug Offenses
Drug crimes are among the most heavily prosecuted offenses in the federal system. Penalties are tied directly to the type and quantity of the substance involved, with the law organizing controlled substances into five schedules. Schedule I (heroin, LSD, ecstasy) and Schedule II (cocaine, methamphetamine, fentanyl) carry the stiffest penalties because the law classifies them as having high potential for abuse.
For large-quantity trafficking in Schedule I or II drugs, federal law imposes a mandatory minimum of ten years in prison, scaling up to life. If the trafficking results in someone’s death or serious injury, the mandatory minimum doubles to twenty years. Fines can reach $10,000,000 for an individual or $50,000,000 for an organization.18Office of the Law Revision Counsel. 21 USC 841 – Prohibited Acts Smaller quantities carry lower mandatory minimums, typically five years, and simple possession without intent to distribute is punished far less severely than trafficking. These mandatory minimums remove much of a judge’s discretion, which is why drug sentencing has been one of the most debated areas of criminal law for decades.
Cybercrimes
The federal Computer Fraud and Abuse Act covers unauthorized access to computer systems and the damage or theft that results. Penalties vary depending on what the person did and whether they have prior convictions. Accessing a computer without authorization to obtain national security information can bring up to ten years for a first offense and twenty years for a repeat offense. Unauthorized access for financial gain or to further another crime carries up to five years, doubling to ten for a second conviction. Intentionally damaging a computer system or the data on it can result in five to twenty years depending on the extent of the harm and whether the offense is a repeat.19Office of the Law Revision Counsel. 18 U.S. Code 1030 – Fraud and Related Activity in Connection With Computers
What the Prosecution Has to Prove
Which “type” of crime a defendant ends up charged with often turns less on what happened than on what the prosecution can prove about the defendant’s state of mind. The same act can land in different categories depending on intent.
Every crime requires a voluntary physical act, or in some cases a failure to act when the law imposes a duty. A reflex, a movement during a seizure, or something done while unconscious does not count. For most offenses, the prosecution must also prove that the defendant had a particular mental state when they acted:
- Purposely, meaning the person specifically intended to bring about a particular result.
- Knowingly, meaning the person was aware their conduct would almost certainly cause a particular result, even if that result was not their primary goal.
- Recklessly, meaning the person consciously ignored a substantial risk that their conduct would cause harm.
- Negligently, meaning the person should have been aware of a substantial risk that a reasonable person in the same situation would have recognized.
Murder typically requires purpose or knowledge, while involuntary manslaughter may only require recklessness or negligence. The physical act and the mental state must happen at the same time: if intent and harm are separated by days or weeks, the concurrence requirement is not met.
A narrow set of crimes called strict liability offenses require no particular mental state at all. Statutory rape is a well-known example: the defendant’s belief about the victim’s age is irrelevant. Certain drug possession charges also fall into this category. Strict liability crimes are generally limited to less serious offenses and tend to carry lighter punishments than crimes requiring proof of intent.20Legal Information Institute. Strict Liability
Corporations and other organizations can be charged too. Under the doctrine of vicarious liability, a business can be held responsible for crimes committed by its employees if those acts occurred within the scope of their employment.21Legal Information Institute. Respondeat Superior In practice, corporate criminal liability is most common in fraud, environmental violations, and workplace safety cases.
Consequences That Outlast the Sentence
Whatever category the conviction falls into, the sentence imposed in court is often only part of what follows. Collateral consequences restrict access to employment, professional licensing, housing, education, and voting. Common examples include bans on firearm possession for people convicted of violent offenses, restrictions on working with children or the elderly for people convicted of abuse, and exclusion from positions of public trust for people convicted of fraud.3National Inventory of Collateral Consequences of Criminal Conviction. National Inventory of Collateral Consequences of Criminal Conviction Sex offense convictions carry registration requirements. Serious traffic offenses can result in license restrictions.
Many of these consequences apply automatically without any judicial decision and remain in effect indefinitely. Some jurisdictions offer a path to relief through expungement or record sealing, which can clear or hide a criminal record under certain conditions. Eligibility varies significantly: some states allow automatic expungement for minor offenses that resulted in dismissal or acquittal, while others require a formal petition and a waiting period that can range from months to years. Federal convictions are much harder to clear, with extremely limited expungement options. Filing fees for a state expungement petition typically range from nothing to a few hundred dollars, though attorney costs can add substantially to the total.
