“Any person who willfully attempts in any manner to evade or defeat any tax imposed by this title or the payment thereof shall, in addition to other penalties provided by law, be guilty of a felony and, upon conviction thereof, shall be fined not more than $100,000 ($500,000 in the case of a corporation), or imprisoned not more than 5 years, or both, together with the costs of prosecution.”
As provided by the DOJ Criminal Tax Manual
“Tax evasion” is a shorthand phrase that many people use for all manner of tax fraud. But the charge of tax evasion, in violation of 26 U.S.C. § 7201, is not necessarily the best one to bring against individuals defrauding the IRS.
Defendants frequently seek to exploit the fact that, in order to establish the crime of tax evasion, the government must prove the existence of a tax due and owing and willfulness. Prosecutors therefore should consider other charges, such as conspiring to defraud the United States, 18 U.S.C. § 371; filing false returns, 26 U.S.C. § 7206; or endeavoring to obstruct the IRS, 26 U.S.C. § 7212(a), as alternatives or supplements to the charge of tax evasion.
