Federal Criminal Law

Federal criminal law — codified primarily in Title 18 of the U.S. Code — defines over 4,500 federal offenses and governs the investigation, prosecution, sentencing, and incarceration of individuals charged with crimes against the United States. Federal criminal jurisdiction is constitutionally limited (unlike state courts, which have general criminal authority): federal crimes must involve a federal interest — interstate commerce, federal property, federal officials, mail and wire communications, national security, or a specific federal statutory grant of jurisdiction. The most commonly charged federal offenses involve fraud (mail fraud §1341, wire fraud §1343, bank fraud §1344, healthcare fraud §1347), controlled substances (manufacturing/distribution under §841), firearms (possessing as prohibited person under §922(g)), immigration (illegal reentry §1326), and money laundering (§1956). Federal prosecution carries distinctive features: the conviction rate exceeds 90%, largely because U.S. Attorneys' offices only bring cases they expect to win; defendants are sentenced under the Federal Sentencing Guidelines (advisory since United States v. Booker, 2005); and federal prison time is served without parole (though good-time credits reduce sentences up to 54 days/year since the First Step Act). The federal system is enforced by the FBI, DEA, ATF, IRS-CI, Secret Service, HSI, and dozens of other agencies — all channeled through U.S. Attorneys' offices in each of the 94 federal districts.

How It Works

Federal criminal law covers offenses that fall within the constitutional authority of the federal government — primarily crimes that cross state lines, involve federal property or agencies, affect interstate commerce, or are specifically designated by Congress. Cases are tried in the federal court system.

Federal criminal jurisdiction is limited to crimes that cross state lines, involve federal property or agencies, affect interstate commerce, or are specifically designated by Congress — most criminal law remains state law, with murder, robbery, assault, and burglary primarily prosecuted in state courts. Federal criminal jurisdiction reaches crimes on federal property (military bases, national parks, federal buildings), crimes crossing state or national borders (interstate drug trafficking, kidnapping, wire fraud), crimes targeting federal interests (tax evasion, immigration violations, counterfeiting), and offenses Congress has specifically federalized (carjacking, identity theft, child exploitation). In practice there is significant overlap — the same conduct can violate both state and federal law — and prosecutors exercise discretion in choosing which system to pursue. Wire fraud (18 U.S.C. § 1343) and mail fraud (§ 1341) are the workhorses of federal white-collar prosecution, with language broad enough — "scheme or artifice to defraud" — to cover virtually any dishonest scheme using electronic communications or the mail. Bank fraud, healthcare fraud, securities fraud, and tax fraud have their own specific statutes; conspiracy (§ 371) allows prosecutors to charge all participants in a fraudulent scheme; and money laundering statutes (§§ 1956–1957) add penalties for moving crime proceeds. The Sarbanes-Oxley Act added § 1519 (document destruction) and § 1350 (CEO/CFO certification fraud) following the Enron and WorldCom scandals.

Federal criminal civil rights statutes address constitutional violations by government officials and hate crimes: 18 U.S.C. § 242 criminalizes the willful deprivation of constitutional rights by anyone acting under color of law — the primary federal tool for prosecuting police misconduct and brutality — while § 249 (the Matthew Shepard and James Byrd Jr. Hate Crimes Prevention Act) covers violent hate crimes motivated by race, color, religion, national origin, gender, sexual orientation, gender identity, or disability. Federal sentencing is governed by the U.S. Sentencing Guidelines, which provide a structured framework based on offense severity and criminal history; since United States v. Booker (2005), the Guidelines are advisory rather than mandatory, though mandatory minimums still apply for many drug offenses, firearms offenses, and some fraud offenses. The First Step Act (2018) reduced some mandatory minimums, expanded safety valve provisions, and expanded earned-time credits. The Computer Fraud and Abuse Act (§ 1030) is the primary federal cybercrime statute, covering unauthorized computer access, computer fraud, trafficking in passwords, and intentional damage to protected computers; the Supreme Court narrowed the scope of "unauthorized access" in Van Buren v. United States (2021), holding the statute does not criminalize misuse of information a person is otherwise authorized to access.

How It Affects You

If you interact with the federal government in any capacity: The most important federal criminal law principle for ordinary people: making a false statement to a federal agent or on a federal form is a federal crime — even if you're not under oath, not under arrest, and not at a formal proceeding.

18 U.S.C. § 1001 criminalizes making a materially false statement to any federal employee in the scope of their authority. This applies to:

An informal conversation with an FBI agent at your door or your workplace
A statement to an IRS auditor
An application for a federal loan (SBA, student loans, FHA mortgages, HUD assistance)
A Customs and Border Protection form (CBP 6059B declaration, FINCEN Form 105 for currency over $10,000)
A federal firearms form (ATF Form 4473)
An immigration benefit application (I-485, N-400, visa applications)
A federal contractor representation or certification
A statement to a federal inspector or OSHA officer

Your right to remain silent applies here. The Fifth Amendment gives you the right to decline to speak to law enforcement — including federal agents — without an attorney present. This right does not require you to be under arrest. If FBI agents, IRS agents, DEA agents, or any other federal investigators come to your door or contact you, you may politely say "I would like to speak with an attorney before answering any questions" — and that ends the interrogation. Saying nothing is legally safe. Lying is a federal crime.

The critical trap: Many people think they can "clear things up" by speaking to federal agents without a lawyer. In practice, agents record interviews and look for any inconsistency, omission, or inaccuracy that can be charged as a false statement. Even if you're innocent of the underlying matter, a misstatement in an interview can become the criminal charge. The DOJ has prosecuted people for § 1001 who were never charged with the underlying crime the agents were investigating. Get a lawyer before you speak.

If you run a business with any federal exposure: Wire fraud (§ 1343) and its siblings are the primary risk. Any business scheme that uses email, phone calls, or the internet and involves even a minor misrepresentation crosses into potential federal criminal territory if it crosses state lines. The statute is broadly written; prosecutors use it liberally.

Voluntary self-disclosure: DOJ's Corporate Enforcement Policy (updated 2024) provides significant incentives for companies that voluntarily disclose misconduct and cooperate with investigations:

Voluntary self-disclosure + full cooperation + effective remediation: presumption of no guilty plea for the company in most cases; fines can be reduced below Guidelines minimum
Full cooperation without self-disclosure: up to 50% fine reduction from Guidelines minimum
No cooperation: full Guidelines calculation plus potential upward adjustments

Self-disclosure must be made before the government opens an investigation or before misconduct is about to be publicly revealed. The disclosure must be complete — not selective. Document the internal investigation and remediation with specificity.

Document preservation: The moment you reasonably anticipate litigation or government investigation — not when you receive a subpoena — you must issue a litigation hold stopping all routine document destruction. Failure to preserve documents can be charged as obstruction under 18 U.S.C. § 1519 (punishable by up to 20 years). Implement a written litigation hold process with automated triggers; do not rely on employee memory.

Healthcare fraud (§ 1347): Medicare/Medicaid fraud is among the most aggressively prosecuted federal crimes. HHS-OIG (Office of Inspector General), FBI, and CMS conduct joint strike force investigations across the country. The False Claims Act (31 U.S.C. §§ 3729–3733) allows employees, competitors, and whistleblowers to file qui tam lawsuits and receive 15-30% of the government's recovery — creating a private enforcement army. If you bill federal healthcare programs, your compliance program must address: medical necessity documentation, proper coding and upcoding, Anti-Kickback Statute compliance (42 U.S.C. § 1320a-7b), Stark Law self-referral prohibitions, and exclusion screening.

Effective compliance program: DOJ's Evaluation of Corporate Compliance Programs guidance (updated 2023) is the standard for what constitutes an effective program — the government uses it to evaluate whether to charge a company. An effective program must be: adequately resourced and empowered (including an independent compliance function with direct board access), based on risk assessment, implemented with genuine training (not checkbox training), monitored through auditing and testing, enforced through consistent discipline, and continuously improved through lessons learned. A compliance program that looks good on paper but is not implemented in practice provides no protection.

If you've been the victim of a hate crime: Federal hate crime prosecution under 18 U.S.C. § 249 is available when state authorities decline to prosecute or when the crime involves conduct affecting interstate commerce.

How to report: Contact your local FBI field office (locate at fbi.gov) or call 1-800-CALL-FBI. The FBI coordinates with local law enforcement on § 249 investigations. You can also report directly to the DOJ Civil Rights Division (justice.gov/crt). File a police report locally as well — even if local prosecution doesn't follow, the documented report supports federal investigation.

What § 249 requires: The government must prove that the offense was committed "because of" the victim's race, color, religion, national origin, gender, sexual orientation, gender identity, or disability — motive is an element of the crime. Circumstantial evidence of motive (statements, prior conduct, social media) is admissible. Unlike some state hate crime statutes, § 249 does not require proof that the crime was in whole or in part motivated by the protected characteristic — "because of" allows partial motivation.

Civil remedies in addition to criminal: Hate crime victims may also have civil claims under 42 U.S.C. § 1985(3) (conspiracy to deprive of equal protection — requires discriminatory animus and two or more persons), state civil rights statutes, and common law. The NAACP Legal Defense Fund (naacpldf.org), Lambda Legal (lambdalegal.org), and ACLU (aclu.org) maintain civil rights referral networks.

If you're a government official, law enforcement officer, or corrections officer: You are specifically subject to 18 U.S.C. § 242 — federal criminal liability for willfully depriving any person of constitutional rights "under color of law."

"Color of law" means acting in your official capacity, using the authority of your position — even if the specific act is unauthorized or illegal under state law. Excessive force, fabricating evidence, coercing confessions, unlawful searches, and deliberate indifference to serious medical needs of prisoners have all been charged under § 242.

"Willfully" requires more than negligence — the officer must know their conduct was unlawful or act with reckless disregard of that risk. This is a higher standard than the § 1983 civil liability "deliberate indifference" standard, but a lower standard than "premeditated." Intentional violation of a known constitutional right satisfies § 242 willfulness.

Penalties: up to 10 years; life imprisonment if the violation results in death or involves kidnapping or aggravated sexual abuse.

§ 242 and false reports: Filing a false police report or evidence submission is a § 1001 false statement to a federal agency if federal authorities are involved, AND can constitute obstruction under § 1503/§ 1512 if it impedes a federal investigation. Government officials are not exempt from these statutes.

State Variations

Federal criminal law applies uniformly across the United States, but:

Most criminal prosecutions occur in state courts under state law — federal cases represent only about 10% of all criminal cases
Dual sovereignty allows prosecution in both state and federal court for the same conduct (not considered double jeopardy)
Some states have adopted their own computer fraud, money laundering, and hate crime statutes that parallel federal law
State sentencing laws vary dramatically — some states have abolished parole, others have indeterminate sentencing
Federal sentencing tends to be harsher than state sentencing for equivalent conduct, particularly for drug and firearms offenses
