The Protecting American Taxpayers Act aims to significantly reduce fraud, waste, and abuse within federal programs and recover improperly disbursed funds. It introduces measures to prevent fraud in child care services by requiring attendance-based billing and robust record-keeping for audits. For healthcare, the bill mandates that the Department of Health and Human Services Inspector General be notified of significant increases in payments or providers in specific geographic areas, triggering audits for substantial increases over time. The legislation prohibits the Small Business Administration from providing financial assistance to businesses whose associates have been convicted of fraud related to covered loans or grants. It also requires the HHS Inspector General to investigate state programs receiving federal funds if payments to providers increase by 10 percent or more within a six-month period. Furthermore, the bill rescinds unobligated balances from various COVID-19 relief acts, directing these funds towards deficit reduction, with a provision for a national security waiver. To enhance transparency and accountability, the bill requires the President's budget submission to include detailed information on improper payment amounts, rates, and corrective actions for each executive agency. It also establishes a "Bonuses for Cost-Cutters" program, incentivizing federal employees to identify surplus agency funds that can be returned to the Treasury for deficit reduction, with agencies able to retain a portion for employee awards. The Act strengthens the integrity of the Temporary Assistance for Needy Families (TANF) program by applying improper payment laws to states, prohibiting the supplanting of state funds with federal aid, and improving data reporting standards. It also restricts U.S. financial assistance to entities controlled by agents of "covered foreign principals," including governments of nations like China, Russia, and Iran. The bill includes provisions to oppose international support for the Taliban, requiring reports on foreign countries and non-governmental organizations providing aid to the group and mandating the suspension of U.S. foreign assistance to such entities. It also rescinds funds previously allocated for Afghanistan reconstruction. Additionally, the "Stop Secret Spending Act" enhances transparency in federal spending by requiring the reporting of "other transaction agreements" on USAspending.gov and mandating annual reports on unreported federal funding. To bolster fraud detection, the legislation requires federal agencies to report detailed payment information to Treasury disbursement systems and grants the Treasury access to the National Directory of New Hires and select tax information for the "Do Not Pay" system. It also extends the statute of limitations to ten years for criminal and civil fraud related to pandemic-era programs and establishes a Veterans Scam and Fraud Evasion Officer within the VA. Finally, the bill expands whistleblower protections for employees and contractors of federal agencies, including those at the Department of Defense and NASA, who report waste, fraud, or public health and safety concerns.
