What Constitutes a Federal Crime? Key Differences Between Federal and State Charges

The Law Offices of Richard L. Cooper, P.A. May 27, 2025

If you or a loved one is facing criminal charges, you might be unsure of what the charges mean, who is coming after you, and what the future holds. Understanding the key differences between federal and state charges can help you better understand the legal system and protect your rights. 

Working with a qualified criminal defense attorney is crucial when you’re facing charges. Here, we break down what federal crimes are, how they differ from state crimes, and what that means for someone accused of a crime in Florida. If you need representation, don't hesitate to contact our firm and set up a free consultation.

What Is a Federal Crime?

A federal crime is any act that violates federal law as established by the United States Congress. These laws apply to the entire country, not just a single state. When someone breaks a federal law, the crime is prosecuted by the United States government, usually through the U.S. Attorney’s Office and tried in federal court. Common federal crimes include:

  • Drug trafficking across state or national borders

  • Mail fraud or wire fraud

  • Bank robbery

  • Child pornography

  • Terrorism or national security threats

  • Immigration violations

  • White-collar crimes (e.g., securities fraud, tax evasion)

  • Crimes committed on federal property (e.g., national parks or military bases)

If you're being investigated by a federal agency like the FBI, DEA, ATF, or ICE, you're likely involved in a matter of federal jurisdiction. 

What Is a State Crime?

In contrast, state crimes are violations of Florida’s criminal code. These are prosecuted by the State Attorney’s Office (also called the district attorney in other jurisdictions) and tried in Florida state courts. These laws vary from state to state and only apply within that particular state’s borders. Examples of state crimes in Florida include:

State crimes are often investigated by local police departments or state agencies like the Florida Department of Law Enforcement (FDLE).

Key Differences Between Federal and State Charges

Now that you understand the basic definitions, let’s look at some of the key differences that matter most when you’re facing criminal charges in Florida:

Jurisdiction

State charges apply to crimes that happen within Florida and don’t involve federal laws or cross state lines. Federal charges are filed when the crime affects interstate commerce, occurs on federal property, or violates a specific federal statute. For example, transporting drugs from Miami to Atlanta could trigger federal drug trafficking charges.

Investigative Agencies

Understanding which investigative agencies are involved in federal versus state crimes is essential. State crimes are investigated by local police, county sheriffs, the Florida Highway Patrol, or the Florida Department of Law Enforcement.

Federal crimes are investigated by federal agencies like the Federal Bureau of Investigation (FBI), Drug Enforcement Administration (DEA), Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), or Immigration and Customs Enforcement (ICE). 

Court System

Federal cases go through the United States District Court for the district in which the crime occurred. Florida has three federal districts:

  • Northern District of Florida (Tallahassee, Pensacola, Gainesville)

  • Middle District of Florida (Tampa, Orlando, Jacksonville)

  • Southern District of Florida (Miami, Fort Lauderdale, West Palm Beach)

State cases are tried in Florida Circuit or County Courts, depending on the severity of the charge. If you find yourself in a situation where you’ve been charged with a crime in one of these districts, contact our law office today for assistance with your case.

Sentencing Guidelines

Federal crimes are subject to the U.S. Sentencing Guidelines, which are typically harsher than Florida’s state sentencing rules. Federal judges have less discretion and are bound by these strict guidelines unless there are exceptional circumstances.

Florida’s state courts use a Criminal Punishment Code that provides a scoring system to determine the sentence. While serious offenses still carry heavy penalties, state judges generally have more flexibility in tailoring sentences.

Prosecutors and Defense Counsel

Federal cases are handled by Assistant U.S. Attorneys (AUSAs). These prosecutors often have fewer cases than their state counterparts, which means they can spend more time building a strong case. You need someone with experience in both jurisdictions if your case could potentially go federal. Contact our firm today to learn more about our services.
