Key Takeaways

  • Tax evasion under 26 U.S.C. 7201 requires proof of a tax deficiency, an affirmative act, and willfulness.
  • IRS criminal cases are document-intensive and often build for years before charges.
  • A good-faith misunderstanding of the tax law defeats willfulness — the Cheek defense.
  • Early counsel can steer an IRS criminal referral toward a civil resolution.

What Federal Tax Evasion Is (26 U.S.C. 7201)

Tax evasion under 26 U.S.C. § 7201 is the willful attempt to evade or defeat any tax, and it includes a variety of potential offenses that can be prosecuted by federal authorities. The prosecution must establish three distinct elements: first, there must be an existing tax deficiency; second, there must be an affirmative act designed to evade this deficiency; third, the defendant's conduct must be willful. Without all three elements proven beyond a reasonable doubt, the government cannot secure a conviction for tax evasion.

Willfulness is perhaps the most critical aspect of proving tax evasion because it requires evidence that the individual acted with an intentional and deliberate purpose to evade their tax obligations. This means the taxpayer must have known they had a legal duty to file or pay taxes but willfully chose not to do so.

How IRS Criminal Investigations Work

The Internal Revenue Service’s Criminal Investigation Division (IRS CI) conducts extensive investigations that are often lengthy and document-intensive, typically taking months or even years. These investigations frequently begin with civil audits that can escalate into criminal referrals if evidence of potential tax evasion is uncovered.

Agents from IRS CI use a variety of investigative techniques to build their cases, including issuing document summonses for bank records, financial statements, and other pertinent documents, as well as conducting interviews of individuals who may have knowledge about the taxpayer's activities. During these investigations, there often are parallel civil and criminal tracks; while the tax deficiency is being determined in a civil audit, the criminal investigation aims to gather evidence necessary for prosecution.

Related Federal Tax Charges

In addition to tax evasion under 26 U.S.C. § 7201, other significant federal tax crimes include willful failure to file a return or supply information (under 26 U.S.C. § 7203), filing false returns, overstatements of credits and refunds, making false statements on documents under penalties of perjury (26 U.S.C. § 7206), structuring financial transactions to evade reporting requirements (31 U.S.C. § 5324), and conspiracy in violation of Klein Conspiracy Statute (18 U.S.C. § 371).

Federal tax cases often involve complex legal issues, including the application of statutes such as structuring laws aimed at preventing cash transactions that avoid reporting requirements.

Defense Strategies in Tax Cases

A robust defense strategy against federal tax charges includes several key elements. First and foremost is challenging the government’s assertion of willfulness. Under Cheek v. United States, a good-faith misunderstanding or misinterpretation of the tax law negates the element of willfulness — the standard is the defendant's actual good faith, not whether the belief was objectively reasonable.

Another defense strategy involves demonstrating reliance on professional advice. If a taxpayer relied on an accountant’s erroneous guidance in filing their returns and had no reason to know it was incorrect, this could undermine the prosecution’s claim of willfulness.

Other common defenses include amending tax returns retroactively where appropriate to show compliance with the law, challenging the government's computation of any alleged deficiency, and arguing that there is no actual tax deficiency based on a legal interpretation favorable to the taxpayer.

Voluntary Disclosure and Other Resolutions

The IRS has established a practice called voluntary disclosure, which allows taxpayers under investigation or audit to come forward before formal charges are filed. The goal of this program is to resolve tax issues civilly rather than criminally.

Counsel can often negotiate with the IRS to achieve a favorable outcome, such as reducing penalties or reaching an agreement that results in civil liability instead of criminal prosecution. When faced with actual criminal charges, working closely with experienced counsel early on may lead to more lenient plea options and resolutions.

A Former Federal Prosecutor's Perspective on Tax Cases

Having built federal prosecutions as a prosecutor, I understand the meticulous nature of how IRS CI builds cases over years. Investigating agents accumulate vast amounts of evidence before presenting their case for prosecution.

This experience informs my approach to defending clients against federal tax charges. Knowing what evidence is necessary and how it fits together enables me to identify weaknesses in the government's case early on, allowing us to take proactive steps toward resolution.
