National Report IRS Tax Fraud Day is observed on April 10 each year in the United States. It was founded by attorney Joel Hesch, who previously served as a Whistleblower Reward Officer for the Department of Justice. The day aims to raise awareness about the I.R.S. Whistleblower Incentive Program and other reward schemes for reporting tax fraud. Hesch later established an independent law firm to assist whistleblowers in claiming rewards under various government programs, including the I.R.S. Tax Fraud Reward Programs. The observance encourages individuals to understand the processes involved in reporting tax fraud and highlights the importance of whistleblowers in combating tax evasion.
