GAO Database Modernization Act of 2023

This bill requires federal agencies to report to the Government Accountability Office (GAO) when they revoke, suspend, replace, amend, or otherwise make rules ineffective. Agencies must submit reports including the rule's title, Federal Register citation, submission date, and details of the changes. The law applies directly to all federal agencies that issue regulations. It includes a sunset provision, ending the requirement six years after enactment (October 1, 2024). The goal is to improve transparency by creating a centralized, up-to-date record of regulatory changes for public access.
