IRS Criminal Investigation: The Agency That Doesn't Lose
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.
Tax Charges as a Prosecutorial Tool
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.
The Willfulness Requirement: The Critical Defense Lever
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.
Offshore Accounts and FBAR Defense
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.
Our Defense Strategy
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.
