What Are Federal Criminal Charges — and How Are They Different From State Charges in Florida?

Federal criminal charges are accusations that a person violated a criminal law of the United States, rather than a law of the State of Florida. They are investigated by federal agencies such as the FBI, DEA, ATF, and Homeland Security Investigations, prosecuted by the U.S. Attorney’s Office, and tried in federal district court — in South Florida, the U.S. District Court for the Southern District of Florida, which holds court in Fort Lauderdale. Under 18 U.S.C. § 3231, federal courts have exclusive jurisdiction over these offenses — a state court cannot hear them.

The label matters because almost everything about the case changes with it: who is prosecuting, how charges are filed, whether you can bond out, and how a sentence is calculated and served. This article explains:

What makes a charge federal instead of state?

Most crimes — theft, assault, burglary, drug possession, DUI — are defined by Florida law and prosecuted by the state. A charge becomes federal when the conduct violates a statute passed by Congress, which generally requires some federal hook. The most common ones:

• Crossing state or national borders. Conduct that moves across state lines or involves imports — drug importation and trafficking conspiracies, interstate fraud schemes, transporting stolen property between states.
• Use of interstate systems. Wire fraud and mail fraud reach schemes that use phones, the internet, banks, or the mail — which is why large fraud cases are so often federal.
• Federal programs, agencies, and funds. Medicare and healthcare fraud, tax offenses, PPP and government-benefit fraud, bank robbery (banks are federally insured).
• Federal property or officers. Offenses committed on federal land — courthouses, military installations, national parks — or against federal officers and employees.
• Subjects Congress regulates directly. Immigration offenses (illegal reentry, harboring, marriage fraud), firearms offenses such as possession by a convicted felon, child exploitation offenses, and counterfeiting.

The same underlying behavior can fall on either side of the line. A fraud that stays inside Florida may be charged as a state offense; the same scheme run through interstate wires may draw a federal indictment. Which sovereign actually files is a charging decision made by prosecutors — not something the accused, or an alleged victim, controls. We cover who controls charging decisions on the state side in Can a Victim Drop Criminal Charges in Florida?

Who investigates and prosecutes federal crimes in South Florida?

Fort Lauderdale sits in the Southern District of Florida, one of the busiest federal districts in the country. The U.S. Attorney’s Office for the Southern District of Florida prosecutes federal crimes across nine counties — including Broward, Miami-Dade, and Palm Beach — with staffed offices in Fort Lauderdale, Miami, West Palm Beach, and Fort Pierce, and more than two hundred Assistant U.S. Attorneys. Cases are tried in the U.S. District Court for the Southern District of Florida, which holds court in Fort Lauderdale, Miami, West Palm Beach, Fort Pierce, and Key West.

The investigating agencies are different, too. Instead of a city police department or the Broward Sheriff’s Office building a case over days or weeks, federal cases are typically built by agencies like the FBI, DEA, ATF, Homeland Security Investigations, IRS Criminal Investigation, and the Secret Service — often over months or years, using grand jury subpoenas, financial records, wiretaps, and cooperating witnesses. By the time an indictment is returned or agents make contact, the government usually believes its case is already complete.

Federal vs. state charges in Florida: the practical differences

	Florida state charges	Federal charges
Law violated	Florida Statutes	United States Code
Who investigates	Local police, sheriff’s office, FDLE	FBI, DEA, ATF, HSI, IRS-CI, Secret Service
Who prosecutes	State Attorney’s Office for the circuit	U.S. Attorney’s Office (Southern District of Florida)
Where the case is tried	County or circuit court (Broward: state courthouse)	U.S. District Court (federal courthouse)
How felony charges are filed	Usually by information; grand jury indictment required only for capital crimes (Fla. Const. art. I, § 15)	Felonies generally require a grand jury indictment unless the defendant waives it
Pretrial release	Bond is common; many charges have standard bond amounts	No bond schedule — a judge holds a detention hearing under 18 U.S.C. § 3142, and some charges carry a presumption of detention
Sentencing framework	Criminal Punishment Code scoresheet (§ 921.002, Fla. Stat.)	Advisory U.S. Sentencing Guidelines, plus statutory mandatory minimums for many drug and firearm offenses
Time actually served	At least 85% of the sentence imposed	No parole; good-conduct credit is capped at 54 days per year of the sentence imposed — roughly 85% served

Two of these differences do the most practical work. First, pretrial release: in federal court there is no posted bond amount to pay. Release or detention is decided at a hearing, and for certain offenses — including drug charges carrying ten years or more — the law presumes detention unless the defense rebuts it. Losing that hearing means remaining in custody for the life of the case, which is one reason the first days after a federal arrest matter so much.

Second, sentencing: federal sentences are driven by the Sentencing Guidelines’ offense levels and criminal history categories, and many federal statutes impose mandatory minimum sentences that a judge cannot go below except in narrow circumstances. Combined with the absence of parole, federal exposure for similar conduct is often — though not always — more severe than state exposure.

Common federal charges in South Florida

The Southern District of Florida sees heavy volume in a recognizable set of cases:

• Drug conspiracy, trafficking, and importation — including maritime and airport interdiction cases
• Wire fraud and mail fraud — investment schemes, business email compromise, telemarketing fraud
• Healthcare and Medicare fraud — South Florida is a national enforcement priority
• Money laundering and structuring
• Firearms offenses — most commonly possession of a firearm by a convicted felon
• Immigration crimes — illegal reentry after removal, alien smuggling, document fraud
• Identity theft and access-device fraud, often charged alongside fraud counts

Many of these carry mandatory minimums or steep guideline ranges, and several — like federal immigration crimes — can also trigger separate immigration consequences for non-citizens, which we explain in How Criminal Charges Can Affect Immigration Status in Florida.

Can the same conduct be charged in both state and federal court?

Yes. Under the dual-sovereignty doctrine, Florida and the United States are separate sovereigns, and double jeopardy does not prevent each from prosecuting the same conduct under its own laws. The U.S. Supreme Court reaffirmed this in Gamble v. United States (2019).

In practice, dual prosecutions are the exception. More commonly, a case that starts with a local arrest is “adopted” federally — a state drug or gun arrest is declined by the State Attorney and re-charged by the U.S. Attorney’s Office, usually because federal penalties are higher or the conduct fits a federal enforcement priority. When that happens, the rules of the case change overnight: different court, different prosecutor, different release rules, different sentencing exposure. A criminal defense attorney handling the state case needs to see the federal risk coming, not react to it after indictment.

What to do if federal agents contact you

Federal cases rarely begin with the charge. They begin with a knock on the door, a grand jury subpoena, or a target letter from the U.S. Attorney’s Office. What happens in that window — before any indictment — often shapes the entire case.

• Do not be interviewed without counsel. Agents are allowed to approach you politely and without warning. Lying to a federal agent is itself a felony, and truthful answers can still build the case. “I’d like to speak with my lawyer first” is a complete answer.
• Do not destroy or delete anything. Obstruction charges are frequently easier to prove than the underlying offense.
• Get counsel involved before charges are filed. In the pre-indictment window, a defense lawyer can sometimes learn your status (witness, subject, or target), engage with the prosecutor, and affect whether and how charges are brought — leverage that mostly disappears after indictment.

Frequently asked questions

How do I know if I’m under federal investigation?

Common signs include federal agents contacting you, your employer, or your associates; a grand jury subpoena for your records or testimony; a target letter from the U.S. Attorney’s Office; or learning that accounts or records have been subpoenaed. Sometimes there is no warning at all before an arrest. Any of these signs is reason to speak with a defense attorney immediately — before speaking with agents.

Are federal charges more serious than state charges?

Often, but not automatically. Federal cases tend to involve longer investigations, more evidence, mandatory minimum sentences, and detention presumptions that state cases lack. But a state felony can carry heavier consequences than a low-level federal offense. What is consistently true is that federal court is less forgiving of missteps early in the case — especially at the detention stage.

Is there bail in federal court?

Not in the way Florida defendants expect. There is no bond schedule to post against. A federal magistrate judge decides release or detention at a hearing under the Bail Reform Act, weighing flight risk and danger to the community, and certain charges carry a rebuttable presumption that no conditions of release are adequate. Preparation for that hearing — family, employment, property, third-party custodians — is often the first major defense project in a federal case.

Can my state case be transferred to federal court?

There is no transfer in the formal sense — the federal government makes its own independent charging decision. But state arrests are regularly declined by the State Attorney and re-charged federally, particularly gun and drug cases that fit federal enforcement priorities. If your conduct plausibly violates federal law, your lawyer should be planning for that possibility from day one.

Is there parole in the federal system?

No. Parole was abolished for federal offenses decades ago. A federal defendant generally serves the sentence imposed, reduced only by good-conduct credit capped at 54 days per year of the sentence — roughly 15% — plus any earned-time programs that apply. Florida’s system reaches a similar floor from the other direction: gain-time cannot reduce a state sentence below 85% of the term imposed.
