What Is a Felony?

A felony is a serious criminal offense that may lead to a prison sentence of more than one year, severe penalties, felony convictions, probation, or long-term restrictions after conviction. Felony charges may involve violent crimes, white-collar crimes, drug trafficking, money laundering, or other major crimes prosecuted under state law or federal law.

Most criminal offenses are classified as misdemeanors or felonies depending on the seriousness of the alleged conduct and the possible penalties.

Difference Between Felonies and Misdemeanors

Usually punishable by more than one year in prisonUsually punishable by less than one year in jail
Often handled in state and federal courtsUsually handled in lower courts

Common Examples of Felony Offenses

Felony offenses may be prosecuted at the state or federal level, depending on the facts of the case, the location of the alleged conduct, and whether federal jurisdiction exists. Some crimes prosecuted under federal statutes involve interstate activity or federal property, while other crimes remain under state jurisdiction and are handled in state courts under state law enforcement authority.

  • Drug trafficking – Drug trafficking cases often involve interstate activity, federal investigations, and federal agencies when drugs cross state lines or national borders.
  • Money laundering – Money laundering charges may involve complex financial transactions, federal investigations, and violations of federal law.
  • Mail fraud – one of the most common federal offenses prosecuted in federal courts under federal statutes.
  • Violent crimes – Serious assaults, armed robbery, and homicide offenses may result in state felony charges or federal felony charges, depending on the circumstances.

Long-Term Consequences of a Felony Conviction

Felony convictions may create life-changing consequences involving employment, housing, firearm rights, immigration status, voting rights, and professional licenses. Federal convictions may also involve supervised release, federal prison, mandatory reporting conditions, and long-term federal restrictions.

Perlman Defense understands how serious felony charges can become and works aggressively to protect clients facing state and federal cases.

What Is a State Felony?

A state felony is a serious crime prosecuted under state law in state courts. State felonies are usually investigated by state law enforcement agencies or local police departments and prosecuted by county or state prosecutors.

Most state crimes involve conduct entirely within a single state and usually fall under state, not federal, jurisdiction.

Crimes Prosecuted Under State Criminal Laws

State law covers many criminal offenses, including assault, robbery, burglary, DUI offenses, domestic violence, and many drug crimes. State crimes are prosecuted under state criminal statutes instead of federal statutes. Each state creates its own sentencing guidelines, criminal procedures, and penalty ranges.

Felonies Handled in State Courts

State felony cases are prosecuted in state courts where judges, prosecutors, and defense lawyers handle criminal charges, plea agreements, sentencing hearings, and trials. These procedures may differ significantly from federal criminal cases handled in federal courts. State sentencing systems may also differ from federal sentencing guidelines.

State Law Enforcement Agencies and Prosecutors

State law enforcement agencies investigate state crimes and present evidence to local or state prosecutors for possible criminal charges. These agencies may include sheriff’s offices, highway patrol agencies, and local police departments. State prosecutors focus mainly on crimes committed within their state's jurisdiction.

What Is a Federal Felony?

A federal felony is a serious criminal offense prosecuted under federal law in federal courts by the federal government. Federal felony cases usually involve federal agencies, federal prosecutors, and crimes committed that affect interstate commerce, federal systems, national borders, or federal property.

Federal felonies often involve interstate activity, large criminal organizations, financial crimes, or conduct involving multiple states.

Crimes Prosecuted Under Federal Law

Federal law covers many federal offenses, including drug trafficking, mail fraud, money laundering, tax evasion, firearms offenses, and white-collar crimes. The United States government usually prosecutes federal cases through the United States Attorney’s Office. Federal prosecutors often spend months or years building federal criminal cases before filing charges.

Federal Jurisdiction

Federal jurisdiction gives federal courts authority to hear criminal cases involving violations of federal law. Under 18 U.S.C. § 3231, federal district courts have original jurisdiction over offenses against the laws of the United States.

Federal felonies involve jurisdiction connected to interstate activity, federal lands, federal property, national borders, or conduct that violates federal law.

Federal Crimes Investigated by Agencies Like the FBI and DEA

Federal agencies such as the Federal Bureau of Investigation and the Drug Enforcement Administration investigate federal crimes involving drug trafficking, money laundering, organized crime, mail fraud, firearms offenses, and tax evasion.

These investigations often involve multiple federal agencies, federal officers, wiretaps, subpoenas, and financial records. Federal investigations are usually more complex than many state investigations.

What Is the Main Difference Between a Federal and State Felony?

The significant difference between state and federal felonies usually concerns enforcement and the court system handling the prosecution. Federal felony cases involve violations of federal law and are handled in federal courts, while state felony charges involve violations of state law and are handled in state courts.

State and federal systems also differ in sentencing guidelines, criminal procedures, mandatory minimum sentences, plea agreement practices, and investigation methods used by law enforcement agencies.

Jurisdiction and Authority to Prosecute Crimes

Jurisdiction determines whether the federal government or state government has the authority to prosecute criminal offenses. Federal jurisdiction usually applies when crimes are committed across state lines, involve federal property, or affect federal systems. State jurisdiction usually applies to crimes occurring within one state.

Differences Between Federal and State Laws

Federal law applies across the United States, while state law varies by state. Some criminal offenses may violate both state and federal law simultaneously. This means the same crime may sometimes lead to both state and federal charges.

Federal Crimes Often Involve Interstate or National Activity

Federal crimes often involve interstate activity, national borders, federal lands, or conduct affecting federal systems and agencies. Drug trafficking, money laundering, and mail fraud are common examples of federal offenses involving interstate conduct. Federal prosecutors frequently pursue larger criminal organizations and conspiracy cases.

State Crimes Usually Occur Within One State

Most state crimes occur entirely within a single state and remain under state jurisdiction. Assault, burglary, domestic violence, and many DUI offenses are usually prosecuted in state courts. State law enforcement agencies commonly handle these investigations.

Differences in Court Systems and Procedures

Federal courts and state courts follow different federal rules, criminal procedures, and sentencing guidelines. Federal judges often follow stricter federal sentencing guidelines and mandatory minimum sentences in federal criminal cases. State sentencing systems may differ significantly depending on the state handling the prosecution.

What Are Common Examples of Federal Felonies?

  1. Drug Trafficking: Under 21 U.S.C. § 841, drug trafficking involves manufacturing, distributing, or possessing controlled substances with the intent to distribute. Many federal drug trafficking cases carry mandatory minimum sentences and long federal prison terms.
  2. Wire Fraud and Mail Fraud: Under 18 U.S.C. § 1341 and Under 18 U.S.C. § 1343, mail fraud and wire fraud involve schemes using mail services, phones, or electronic communications to commit fraud.
  3. Money Laundering: Under 18 U.S.C. § 1956 and Under 18 U.S.C. § 1957, money laundering involves financial transactions intended to hide criminal proceeds or illegally move funds.
  4. Federal Firearms Crimes: Under 18 U.S.C. § 922, federal firearms crimes may involve illegal possession, trafficking, or firearm possession by prohibited persons.
  5. Bank Robbery: Under 18 U.S.C. § 2113, bank robbery involves taking money or property from federally insured financial institutions through force or intimidation.
  6. Healthcare Fraud and Tax Evasion Crimes: Healthcare fraud and tax evasion cases often involve white-collar crimes investigated by federal agencies and prosecuted in federal courts.

What Are Common Examples of State Felonies?

  • Assault and Violent Crimes: Serious violent crimes such as aggravated assault and homicide are commonly prosecuted as state felonies.
  • Burglary and Robbery Offenses: Burglary and robbery charges often involve unlawful entry, theft, or the use of force against another person.
  • DUI Causing Serious Injury or Death: DUI offenses causing severe injuries or fatalities may result in felony charges under state law.
  • Drug Possession and Distribution Under State Laws: State law enforcement agencies often prosecute possession and distribution offenses under state drug laws.
  • Domestic Violence and Sexual Offenses: Domestic violence and sexual offenses may carry severe penalties and lengthy prison sentences in state courts.

How Are Federal and State Penalties Different?

Federal and state penalties differ because federal criminal cases and state felony cases follow different sentencing guidelines, criminal statutes, and supervision systems.

Federal convictions often involve mandatory minimum sentences, federal sentencing guidelines, supervised release, and stricter prison terms. At the same time, state penalties may vary greatly depending on state law, prior criminal history, and sentencing procedures used in state and federal systems.

Federal Mandatory Minimum Sentences

Some federal offenses carry mandatory minimum sentences that federal judges must impose after conviction. Drug trafficking and firearms cases are common examples. Mandatory minimum penalties may greatly increase exposure to federal prison.

State Sentencing Guidelines and Penalty Ranges

State sentencing guidelines vary between states and often provide different penalty ranges depending on criminal history and aggravating factors. Some states classify offenses as Class B, Class C, Class D, Class E, or capital felonies. Penalties may differ significantly from one state to another.

Differences in Probation, Parole, and Supervised Release

Federal criminal cases usually involve supervised release instead of parole after release from federal prison. Many state systems still allow parole depending on the offense and state law. The rules for supervision violations also differ between state and federal systems.

Criminal Fines and Restitution Orders

Federal and state courts may impose criminal fines, restitution orders, and court costs after felony convictions. Financial penalties may continue long after a prison sentence ends. Federal convictions often involve additional forfeiture penalties.

Asset Forfeiture in Federal Criminal Cases

Federal prosecutors may seek forfeiture of bank accounts, money, vehicles, or property connected to federal crimes. Federal forfeiture laws are often broader than some state laws. This may create serious financial pressure for defendants and families.

What Are the Penalties for Federal Felonies?

Federal felony penalties can be extremely severe because federal judges often impose long prison sentences, large criminal fines, mandatory minimum sentences, supervised release, and major restrictions after conviction.

Federal sentencing guidelines, prior criminal history, financial losses, weapon involvement, and the seriousness of the criminal offenses may all affect the final sentence imposed in federal criminal cases.

Federal Prison Sentences That Can Exceed 20 Years or Life

Drug trafficking convictions under 21 U.S.C. § 841 may carry mandatory minimum sentences of 5, 10, or 20 years, depending on drug quantity and prior convictions.

Wire fraud under 18 U.S.C. § 1343 can result in up to 20 years in federal prison, or up to 30 years if a financial institution is involved.

Money laundering under 18 U.S.C. § 1956 carries penalties of up to 20 years in prison and fines up to $500,000 or twice the value of the criminal proceeds.

Federal Criminal Fines

Under 18 U.S.C. § 3571, individuals convicted of federal felonies may face fines up to $250,000 for many offenses. Organizations may face fines reaching $500,000 or more. Courts may also impose restitution and forfeiture penalties.

Supervised Release and Long-Term Federal Restrictions

Federal courts may impose supervised release under 18 U.S.C. § 3583 after imprisonment. Convicted individuals may face firearm restrictions, immigration consequences, employment barriers, and other long-term federal restrictions. Federal convictions may continue affecting a person’s future for many years.

What Are the Penalties for State Felonies?

State felony penalties depend on the seriousness of the offense, sentencing guidelines, criminal history, and the state law under which the prosecution occurs. State felony charges may lead to prison, probation, parole, community supervision, criminal fines, restitution, and major long-term effects involving employment, civil rights, and housing opportunities after felony convictions.

Prison Sentences Based on State Sentencing Laws

State prison terms depend on state sentencing laws and the offense's classification. Some states impose enhanced penalties for repeat offenders or violent crimes. Serious state crimes may still carry life sentences.

State Criminal Fines and Restitution Requirements

State courts may impose criminal fines, restitution orders, and financial penalties after felony convictions. Defendants may also face court fees and supervision costs. Financial obligations may continue for years after sentencing.

Probation, Parole, and Community Supervision

Many state felony convictions involve probation, parole, or community supervision after release from prison. Defendants must follow strict conditions to avoid additional penalties. Violations may result in further jail or prison time.

Habitual Offender and Three-Strikes Enhancements

Some states impose enhanced penalties for repeat offenders under habitual offender laws or three-strikes statutes. Prior felony convictions may greatly increase the potential for prison exposure. These laws are often used in violent crime cases.

Long-Term Effects on Employment and Civil Rights

State felony convictions may affect employment, voting rights, firearm ownership, housing eligibility, and professional licensing. Even after a prison sentence ends, felony convictions may continue affecting daily life.

Perlman Defense fights aggressively to help clients avoid permanent criminal records and severe penalties.

Can Someone Face Both Federal and State Charges?

Yes. A person may face both federal and state charges when the same crime violates both federal law and state law.

Drug trafficking, money laundering, firearms offenses, and fraud cases sometimes involve federal and state investigations at the same time, especially when crimes are committed across state lines or involve interstate activity. State and federal cases can become extremely serious because defendants may face prosecution in both state and federal courts.
