Requires the Government Accountability Office to check each reported bill for new federal programs, offices, or initiatives that would duplicate or overlap existing ones, and to publish those findings.

• Directs GAO to determine whether each reported bill creates a risk of a new program, office, or initiative that duplicates or overlaps an existing one identified in its annual duplication and overlap reports.
• Requires GAO to name the new program, the bill section that creates it, and the existing report that identifies the overlap, then publish this on its website and send it to the CBO Director and the reporting committee.
• Allows the CBO Director to add GAO's findings as a supplement to the cost estimate for the bill.
• Takes effect on the earlier of 60 days after OMB's next website update under 31 U.S.C. 1122(a), or the start of a new Congress more than one year after enactment.
