The most common federal crimes and their penalties cluster in four categories: immigration offenses, drug trafficking, firearms crimes, and fraud. Together they account for more than four out of every five federal prosecutions. In fiscal year 2024, the U.S. Sentencing Commission reported that immigration cases made up 30 percent of the federal caseload, drug offenses about 29.6 percent, firearms crimes 13.2 percent, and fraud or theft roughly 8.6 percent.1United States Sentencing Commission. 2024 Annual Report Penalties range from a year or less for the lowest-level offenses to life imprisonment for large-quantity drug trafficking, armed career criminals, and violent crimes with federal victims.
What Makes a Crime Federal
A crime becomes a federal offense when it violates a law passed by Congress, happens on federal land, targets a federal employee or agency, or crosses state lines. Robbing a federally insured bank, shipping drugs from one state to another, and defrauding someone through the U.S. mail are all federal because they involve a federal interest or interstate activity. The 93 U.S. Attorney’s Offices across the country handle these prosecutions, supported by agencies like the FBI, DEA, ATF, and IRS Criminal Investigation.2U.S. Department of Justice. Offices of the United States Attorneys
The same conduct can be charged as both a federal and state crime. Under the dual sovereignty doctrine, a drug dealer arrested by state police can also face a separate federal indictment for the same transaction. Double jeopardy doesn’t bar the second prosecution because each government is enforcing its own laws.
Drug Trafficking
Federal drug cases consistently sit at or near the top of the docket every year. The federal government typically steps in when drugs move across state or national borders, when quantities are large, or when the case ties into organized distribution networks. Under federal law, manufacturing, distributing, or possessing controlled substances with intent to distribute is illegal regardless of which specific drug is involved.3Office of the Law Revision Counsel. 21 USC 841 – Prohibited Acts A
Penalties scale with the type and quantity of drug. At the highest level, trafficking large amounts of heroin (1 kilogram or more), cocaine (5 kilograms or more), fentanyl (400 grams or more), or methamphetamine (50 grams or more of pure substance) carries a mandatory minimum of 10 years and a maximum of life in prison. If someone dies from using the drugs, the mandatory minimum jumps to 20 years. A second serious drug felony conviction raises the floor to 15 years.3Office of the Law Revision Counsel. 21 USC 841 – Prohibited Acts A Even smaller quantities trigger mandatory minimums of five years at the next tier down. In these cases federal sentencing hits hardest, and most defendants have little room to negotiate without cooperating.
Immigration Offenses
Immigration crimes now lead the federal docket, driven largely by prosecutions along the southern border. The most commonly charged offense involves smuggling people into the country or helping them stay. Knowingly bringing someone into the United States outside a designated port of entry, transporting them within the country while knowing they’re here unlawfully, or hiding them from detection are all separate crimes.4Office of the Law Revision Counsel. 8 USC 1324 – Bringing in and Harboring Certain Aliens
Penalties depend on the circumstances. Smuggling for profit carries heavier sentences than helping a family member. If someone is seriously injured or killed during the smuggling, or if the offense involves large numbers of people, the penalties escalate sharply. Illegal reentry after a prior deportation is another high-volume federal charge, and a prior removal based on national security grounds carries a mandatory minimum of 10 years.
Firearms Offenses
Federal firearms charges are the third most common category, and the one most people encounter is possession by a prohibited person. Federal law bars several categories of people from having any firearm or ammunition, including anyone convicted of a crime punishable by more than one year in prison, fugitives, users of controlled substances, anyone subject to certain domestic violence restraining orders, and people convicted of misdemeanor domestic violence.5Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts
A convicted felon caught with a gun faces up to 10 years in federal prison. If the person has three or more prior convictions for violent felonies or drug trafficking, the Armed Career Criminal Act imposes a 15-year mandatory minimum with no possibility of parole.6Department of Justice. Quick Reference to Federal Firearms Laws Separate from possession charges, using or carrying a firearm during a drug trafficking crime or crime of violence triggers a mandatory 10-year add-on sentence for discharging the weapon, served consecutively to any other sentence.
Fraud and Financial Crimes
Federal fraud charges cover everything from email scams to elaborate tax evasion schemes. Each one involves deception combined with either the use of interstate communications or a direct hit to the federal treasury.
Mail and Wire Fraud
These two statutes are the workhorses of federal white-collar prosecution. Mail fraud covers any scheme to defraud that uses the U.S. Postal Service or a private interstate carrier.7Office of the Law Revision Counsel. 18 USC 1341 – Frauds and Swindles Wire fraud covers the same type of scheme carried out through phone calls, emails, text messages, or any other electronic communication crossing state lines.8Office of the Law Revision Counsel. 18 USC 1343 – Fraud by Wire, Radio, or Television Both carry up to 20 years in prison. If the fraud targets a financial institution, the maximum climbs to 30 years and a $1 million fine.
Prosecutors use these statutes because they’re flexible. Almost any fraud that touches a wire transfer, a phone, or a piece of mail can be charged federally. Investment scams, insurance fraud, business email compromise schemes, and romance scams all routinely end up as wire fraud cases.
Tax Crimes
Tax evasion requires proof that someone willfully tried to defeat or avoid paying a tax they owed. A conviction carries up to five years in prison and a fine of up to $100,000 for individuals ($500,000 for corporations).9Office of the Law Revision Counsel. 26 USC 7201 – Attempt to Evade or Defeat Tax
Filing a false return is a separate offense. Signing a tax document you know contains false information on any material point carries up to three years in prison and a $100,000 fine.10Office of the Law Revision Counsel. 26 USC 7206 – Fraud and False Statements Tax professionals who help prepare fraudulent returns face the same penalties. These cases don’t require huge dollar amounts. Prosecutors care more about the willfulness of the deception.
Money Laundering
Money laundering involves conducting a financial transaction with proceeds from illegal activity, either to disguise the money’s origin or to promote further criminal conduct. A conviction carries up to 20 years in prison and a fine of up to $500,000 or twice the value of the laundered funds, whichever is greater.11Office of the Law Revision Counsel. 18 USC 1956 – Laundering of Monetary Instruments Federal prosecutors frequently stack money laundering charges on top of drug trafficking or fraud cases because the same criminal proceeds generate separate offenses each time they move through the financial system.
Other Federal Charges You’ll Hear About
Beyond the big four categories, a handful of other federal offenses come up often enough that anyone looking into federal charges should know what they carry.
Bank Robbery
Robbing any bank, credit union, or savings institution whose deposits are federally insured is automatically a federal crime, regardless of whether you cross state lines. A basic bank robbery carries up to 20 years in prison.12Office of the Law Revision Counsel. 18 USC 2113 – Bank Robbery and Incidental Crimes The FBI investigates nearly all bank robberies in the United States because virtually every bank carries federal deposit insurance.
Kidnapping
Kidnapping becomes a federal crime when the victim is transported across a state line, when the offender uses interstate communication to further the crime, or when the victim is a federal official or foreign diplomat. Federal kidnapping carries a sentence of any term of years up to life imprisonment.13Office of the Law Revision Counsel. 18 USC 1201 – Kidnapping If the victim is a child under 18, the mandatory minimum is 20 years.
Cybercrimes
The Computer Fraud and Abuse Act is the primary federal cybercrime statute. It covers unauthorized access to protected computers, which the law defines broadly to include any computer used in interstate commerce or communication, as well as computers belonging to financial institutions and the federal government.14Office of the Law Revision Counsel. 18 USC 1030 – Fraud and Related Activity in Connection With Computers That definition effectively reaches any computer connected to the internet. Penalties run from one year for basic unauthorized access up to 20 years or more when the conduct causes significant damage or is committed for commercial gain. Cybercrime charges frequently overlap with wire fraud when the computer intrusion is part of a broader financial scheme.
Human Trafficking
Sex trafficking of a child under 14, or sex trafficking accomplished through force, fraud, or coercion, carries a mandatory minimum of 15 years and a maximum of life imprisonment. When the victim is between 14 and 17 and no force or coercion is involved, the mandatory minimum is 10 years.15Office of the Law Revision Counsel. 18 USC 1591 – Sex Trafficking of Children or by Force, Fraud, or Coercion Forced labor offenses, which cover compelling someone to work through threats, physical restraint, abuse of the legal system, or psychological coercion, carry up to 20 years, or life if the victim dies or the offense involves kidnapping or sexual abuse.16Office of the Law Revision Counsel. 18 USC 1589 – Forced Labor
RICO
The Racketeer Influenced and Corrupt Organizations Act targets criminal enterprises rather than isolated acts. A RICO charge requires proof that someone participated in an enterprise through a pattern of racketeering activity, which federal law defines to include dozens of underlying crimes ranging from bribery and extortion to drug trafficking, mail fraud, and murder.17Office of the Law Revision Counsel. 18 USC Chapter 96 – Racketeer Influenced and Corrupt Organizations A conviction carries up to 20 years in prison, or life if the underlying racketeering activity itself carries a life sentence. On top of prison time, the court must order forfeiture of any interest in the criminal enterprise and any property derived from the racketeering.18Office of the Law Revision Counsel. 18 USC 1963 – Criminal Penalties That’s why RICO indictments often name dozens of defendants at once.
How Federal Sentencing Actually Works
Knowing the statutory maximum for an offense tells you only part of the story. Three features of federal sentencing determine what a defendant actually serves.
Federal judges start with the U.S. Sentencing Guidelines, which calculate a recommended range based on the severity of the offense and the defendant’s criminal history.19United States Sentencing Commission. Proposed 2026 Amendments to the Federal Sentencing Guidelines Published January 2026 The guidelines are advisory, so judges can go above or below the range when circumstances warrant it.
Mandatory minimums work differently. When Congress writes a minimum sentence into a statute, the judge cannot go below it regardless of what the guidelines recommend. Drug trafficking and firearms offenses carry the most commonly encountered mandatory minimums. The only reliable way around one is “substantial assistance,” where the defendant cooperates with prosecutors and the government files a motion asking the judge to depart below the floor.
Federal prison sentences almost always include a term of supervised release afterward, which functions like parole. The maximum supervised release term depends on the severity of the offense: up to five years for the most serious felonies, up to three years for mid-level felonies, and up to one year for less serious felonies and misdemeanors.20Office of the Law Revision Counsel. 18 USC 3583 – Inclusion of a Term of Supervised Release After Imprisonment Violating the conditions of supervised release can send you back to prison beyond the original sentence.
