What it is:
How it works (Example):
For example, let's say John owns a painting business. As an employer, he dutifully withholds payroll taxes from his employees' paychecks. However, John fails to remit those funds to the IRS and instead uses the money for a vacation and a new car. One of his employees finds out about the activity and reports him using IRS Form 3949-A (though he could also send an anonymous letter to the IRS). The IRS investigates and determines that John has committed tax fraud, which is a felony.
Other examples of tax fraud might include deliberately underreporting or omitting income, making false accounting entries or keeping two sets of books, taking deductions that the taxpayer is not entitled to, claiming personal expenses as business expenses or hiding assets.
Why it Matters:
Tax fraud cheats the government out of millions of dollars a year. It is illegal and punishable by fines, penalties, interest, and/or prison time. It is important to note, however, that tax fraud generally requires willful and intentional activity for the purpose of lowering a tax liability, not mistakes or accidental misreporting.
