IRS Criminal Investigation has a 90%+ conviction rate and investigates only cases it intends to prosecute. In the Southern District of Florida, federal tax fraud cases overlap heavily with money laundering, healthcare fraud, and drug trafficking, making tax charges the vehicle by which prosecutors reach defendants whose other conduct is harder to prove.
IRS Criminal Investigation investigates fewer than 3,000 cases per year nationally, and its conviction rate exceeds 90%. Unlike civil tax audits, which can be resolved through amended returns, payment agreements, and penalties, an IRS-CI investigation signals that the government has already decided a prosecution is warranted and is building the evidentiary record. By the time a special agent requests an interview, the investigation has typically been running for 12 to 24 months.
In the Southern District of Florida, federal tax cases are heavily concentrated in three areas: healthcare fraud overlay cases where IRS-CI follows financial proceeds from fraudulent Medicare and Medicaid billing; drug trafficking cases where unreported income from narcotics sales creates tax exposure; and offshore account cases involving SDFL's large population of international business owners with foreign financial interests.
Federal prosecutors frequently use tax charges tactically. When the primary conduct, drug trafficking, healthcare fraud, public corruption, creates evidentiary challenges, tax charges provide an alternative path to conviction because the proof is mathematical: the government shows income was received and not reported. Al Capone was not prosecuted for running organized crime, he was prosecuted for federal tax evasion.
This prosecutorial strategy means tax charges often accompany other federal offenses in SDFL indictments. A healthcare fraud defendant may face § 1347 counts for the fraudulent billing and § 7201 counts for failing to report the fraudulent proceeds as income. A drug trafficker faces § 841 drug counts and § 7201 counts for unreported cash income. The tax charges multiply both the guideline range and the statutory maximum exposure substantially.
Federal tax crimes require willfulness: intentional, voluntary violation of a known legal duty. This is a higher mental state than negligence or even recklessness. Good faith is a complete defense.
A defendant who relied on an accountant to prepare their returns, even if those returns contained material errors, did not necessarily act willfully. A defendant who had a genuine, good-faith belief, however incorrect, that a particular income item was not taxable did not act willfully. The Supreme Court has held that a mistake of law, if held in good faith, precludes willfulness even in tax cases.
This is the primary defense lever in tax prosecutions, and we develop good faith evidence, the defendant's reliance on professional advice, the complexity of the tax issues involved, the absence of classic fraud indicators, and the defendant's overall tax compliance history, from the earliest stages of representation.
South Florida's international business community creates a substantial population of taxpayers with legitimate offshore financial interests who face criminal exposure from FBAR compliance failures. The willful standard for FBAR criminal liability is contested, courts have disagreed on whether "willful blindness" satisfies the intent requirement, and we litigate that question aggressively.
For clients in ongoing civil FBAR examinations with potential criminal exposure, we coordinate strategy across the civil and criminal tracks simultaneously, because concessions made in civil proceedings can be used as evidence of willfulness in criminal cases.
Early engagement with IRS-CI. When a special agent requests a meeting, the investigation is already advanced. We engage immediately, assess exposure, and in appropriate cases present pre-indictment arguments that have resolved matters without prosecution.
Attacking willfulness. We develop the complete good faith record, accountant reliance, consistent historical reporting, complexity of the tax treatment, absence of affirmative concealment, that undermines the government's willfulness proof.
Contesting the loss calculation. We challenge the government's income reconstruction methodology forensically, with expert testimony where necessary, to minimize the calculated tax loss that drives both charges and sentencing.
Parallel IRS civil resolution. In cases where criminal exposure exists alongside civil deficiency, we coordinate strategy to protect against self-incrimination while pursuing civil resolution that can reduce criminal exposure.
Tax avoidance is legal, using lawful deductions, credits, and planning strategies to minimize your tax liability. Tax evasion under 26 U.S.C. § 7201 is a federal felony: willfully attempting to evade or defeat any tax or the payment thereof through affirmative acts of concealment, false statements, or failure to report income. The essential element that separates the two is willfulness, intentional, voluntary violation of a known legal duty. Good faith belief that a transaction was not taxable, reliance on a tax professional's advice, or a genuine dispute about the tax treatment of income are all relevant to the willfulness inquiry and can constitute complete defenses.
IRS Criminal Investigation (IRS-CI) initiates investigations based on referrals from civil examination agents who identify indicators of fraud, whistleblower complaints, grand jury referrals from other federal investigations (especially healthcare fraud and drug trafficking cases), Suspicious Activity Report analysis from FinCEN, and FBAR violation referrals from the Financial Crimes Enforcement Network. In the SDFL, the most common trigger is a parallel federal criminal investigation, when the DEA, FBI, or HHS-OIG opens a drug trafficking, healthcare fraud, or corruption case, IRS-CI is brought in to follow the money and add tax charges. The presence of IRS-CI in a federal investigation is always a signal that the government intends to prosecute.
Tax loss is calculated as the additional tax owed that the defendant attempted to evade, meaning prosecutors must reconstruct what your true tax liability should have been and compare it to what was reported. For cash-intensive businesses, the IRS uses the bank deposits method, the net worth method, or the specific item method to reconstruct income from indirect evidence. Each of these methods involves assumptions and estimations that we challenge with forensic precision. The tax loss amount drives both the statutory counts charged (each year is a separate count) and the guidelines sentencing range under USSG § 2T1.1.
The Report of Foreign Bank and Financial Accounts (FBAR) requires U.S. persons with foreign financial accounts exceeding $10,000 to file annual reports with FinCEN. Willful failure to file is a federal crime under 31 U.S.C. § 5322, carrying up to 5 years per violation. In practice, FBAR criminal prosecution is reserved for defendants who affirmatively concealed offshore accounts from the IRS, used nominee accounts or shell corporations to hide assets, or whose offshore holdings were connected to other federal crimes. The civil penalties for willful FBAR violations, up to 50% of the account balance per year, can be financially devastating even without criminal prosecution.
Yes, a civil examination can transform into a criminal referral without warning. When a civil examination agent identifies badges of fraud, large understatements, multiple years of consistent underreporting, false books and records, implausible business expenses, they are required to suspend the civil examination and refer the case to IRS-CI. At that point, the investigation shifts entirely to criminal procedures. If you are in an ongoing civil audit and you have concerns about potential fraud indicators in your returns, retaining experienced federal criminal defense counsel immediately, before the civil examination concludes, is essential.
26 U.S.C. § 7201 (tax evasion) carries up to 5 years per count, with each tax year a separate count. § 7206(1) (filing false return) carries 3 years per count. § 7203 (willful failure to file) is a misdemeanor at 1 year per count. Actual sentences are driven by USSG § 2T1.1, where the 'tax loss' replaces 'loss amount' as the offense-level driver. A tax loss between $250,000 and $550,000 produces a base offense level of 18 (27 to 33 months for a first-time defendant). Tax losses above $1.5 million produce base offense level 22 or higher. Sophisticated means, use of foreign accounts, and obstruction enhancements add levels. Tax cases that overlap with money laundering quickly produce double-digit-year sentencing ranges because § 1956 carries a 20-year maximum per count.
Tax evasion under 26 U.S.C. § 7201 requires three elements: an additional tax due and owing, willfulness, and an affirmative act of evasion (concealment, false statement, structuring, double bookkeeping). It is the most serious tax felony, carrying 5 years per count. Filing a false return under § 7206(1) is narrower: it requires only that the defendant willfully filed a return that they did not believe to be true and correct as to every material matter. § 7206(1) does not require proof of a tax due and owing or an affirmative evasion act, just the false return itself. Prosecutors frequently charge § 7206(1) when they can prove the falsity of the return but cannot establish a clean tax loss number, and they charge § 7201 when they have built the full evasion case.
Yes, but the defense requires careful development. Reliance on a tax professional is a complete defense to willfulness if you can show: you provided the preparer with complete and accurate information, you reasonably relied on the preparer's expertise, and you had no reason to know the return was false. The defense fails when the government can show you withheld information, you reviewed the return and knew of false items, or the preparer was acting under your direction. United States v. Bishop and its progeny support reliance defenses where the documentation supports it. The first step in building this defense is preserving every email, engagement letter, organizer, and document exchange with the preparer, before the government subpoenas them and gets there first.
No. IRS-CI special agents are sworn law enforcement, not civil examiners. By the time they appear in person or call, they have typically been investigating for 12 to 24 months and have already developed a substantial documentary record. Statements made to IRS-CI are not protected by any tax preparation privilege and can be used directly at trial. Inconsistencies between your statements and what the documents show become 18 U.S.C. § 1001 or § 7206(1) charges. Politely decline to discuss the matter, take the agents' business cards, and call experienced federal tax defense counsel immediately. The Kovel privilege, when properly invoked through counsel, can protect subsequent communications with your accountant during the criminal phase.
Possibly, but timing controls everything. The IRS Voluntary Disclosure Practice (VDP) is available only if you come forward before the IRS becomes aware of the noncompliance through any source: a referral, a third-party report, a Suspicious Activity Report, or a parallel investigation. Once IRS-CI opens a file or any federal agency develops information about your noncompliance, the disclosure is no longer 'voluntary' and the program is unavailable. The VDP does not guarantee no criminal prosecution, but participation is a significant mitigating factor and most VDP cases resolve civilly. Filing amended returns without a formal voluntary disclosure does not provide the same protection and can actually create new false-statement exposure if the amended returns are themselves inaccurate. Always run a voluntary disclosure decision through experienced federal tax criminal counsel.

Federal financial crime investigations employ sophisticated tactics that can lead to decades in prison. Understanding FBI methods, legal frameworks, and enforcement priorities is crucial for anyone facing scrutiny.
Federal prosecutors are changing their approach to white-collar cases. Here are the key trends defense attorneys need to watch in 2024.
Cooperation in federal court is not simply about providing information to the government. When properly structured, it requires careful preparation, strategic timing, and a disciplined understanding of how prosecutors and sentencing courts evaluate credibility and assistance.
Federal money laundering charges under 18 U.S.C. § 1956 carry up to 20 years per count. When federal prosecutors target financial transactions in South Florida, you need defense counsel who knows exactly how they build these cases, and how to dismantle them.
Wire fraud under 18 U.S.C. § 1343 is one of the most frequently charged federal crimes, and one of the most flexible tools in a federal prosecutor's toolkit. Any scheme to defraud that uses a wire communication crosses into federal jurisdiction. The penalty is up to 20 years per count.
PPP and EIDL prosecutions are still moving, and the statute of limitations is ten years. SBA OIG subpoenas, grand jury target letters, and indictments are landing five years after the loans closed. If you received a PPP or EIDL loan and now have a federal investigator at your door, the case is already built.
When the government investigates an organization or an executive, the advantage goes to the side that knows how federal agents actually build, value, and prove a case. We now bring that perspective in-house — for our own defense work and as a consulting resource for organizations and executives facing federal exposure.
