Although the IRS conducts tax audits each year, tax fraud is, and continues to be a problem in the U.S. In fact, for the 2010 fiscal year, the IRS initiated 2,188 investigations against individuals suspected of this white-collar crime; 1,055 individuals were convicted of tax fraud. If you suspect that someone is committing this crime, you can play a role in deterring tax fraud by reporting the crime. Fortunately, the IRS offers individuals who report this crime the opportunity to remain anonymous.
