The primary difference between tax fraud and tax evasion appears to be their legal definition. IRC Section 7201 clearly defines tax evasion as either the willful attempt to evade or defeat the assessment of a tax, or the willful attempt to evade or defeat the payment of a tax. Conversely, the IRS defines tax fraud as an intentional wrongdoing, on the part of a taxpayer, with the specific purpose of evading a tax known or believed to be owing. Tax fraud is generally accepted as a broader definition of tax-related financial crime.
