This bill creates new fraud prevention and financial integrity functions within the Treasury, including the Do Not Pay system and a governmentwide data analysis program. It authorizes secure data sharing among agencies to prevent improper payments and establishes a permanent Office of the Inspector General for Fraud, Accountability, and Recovery to audit and report on federal fund fraud. The Treasury must ensure privacy protections, enter data sharing agreements, provide recommendations for large federal spending, and oversee a transition of functions by December 31, 2028.
