This legislation requires the Secretary of the Treasury to provide annual reports to Congress on two key areas: tax fraud prevention and tax law complexity . The first report, due within 12 months of enactment and annually thereafter, focuses on the Internal Revenue Service's efforts to combat various forms of tax fraud, including first-person fraud and stolen identity refund fraud. The fraud prevention report must include a detailed analysis of efforts undertaken by the IRS and Security Summit members, as well as interactions with non-Security Summit tax filing providers. It requires specific information shared, guidelines provided, and recommendations for improving data, analytics, and collaboration in fraud detection. Furthermore, the report must present numerical data on the amount of each type of tax fraud identified during the most recent tax filing season, including the total dollar amount of fraudulent refund claims that were erroneously disbursed or successfully disallowed. A significant provision of the bill mandates that redacted data from these fraud reports be made publicly available on the IRS website. Separately, the legislation clarifies that an existing report submitted by the IRS does not fulfill the statutory requirement for an annual analysis of the sources of complexity in the administration of federal tax laws , thereby reinforcing the need for a distinct complexity report.
