The "Duplication Scoring Act of 2025" aims to enhance governmental efficiency by requiring the Comptroller General of the United States to analyze proposed legislation for potential duplication with existing federal programs. This analysis applies to any public bill or joint resolution reported by a congressional committee , including appropriations and budget committees. For each covered bill, the Comptroller General must determine if it creates a new duplicative or overlapping feature , defined as a new federal program, office, or initiative that would duplicate an existing one previously identified in a GAO duplication and overlap report. If such a risk is found, the Comptroller General must identify the name of the new program, the specific section of the bill establishing it, and the relevant GAO report that identified the existing duplicative feature. The information gathered by the Comptroller General is then submitted to the Director of the Congressional Budget Office and the committee that reported the bill. It is also required to be published on the Government Accountability Office's website. The CBO Director may include this information as a supplement to the bill's cost estimate, providing Congress with a comprehensive view of potential redundancies before legislation is enacted.
