Improper Payments Transparency Act

This bill requires federal agencies to include detailed explanations about improper payments in the President's annual budget submission. Specifically, agencies must provide narratives explaining the causes of improper payments, trends in payment errors over the past three years, and updates on incomplete corrective actions. It directly affects executive agencies that already report on improper payments under existing law, such as those managing Social Security, Medicare, or federal benefit programs. The requirement aims to increase transparency around payment errors without changing how agencies manage or prevent them.
