The Modernizing Government Technology Reform Act seeks to improve the functionality and impact of the Technology Modernization Fund (TMF) by amending its governing statute. It clarifies that TMF funds are to be used for acquiring and developing information technology to modernize, retire, or replace legacy IT systems , enhance cybersecurity and privacy, improve efficiency, and bolster agencies' ability to perform their missions and deliver public services. A key provision reinforces that funds transferred from the TMF must be reimbursed to ensure the fund's operational viability until its sunset. The bill introduces stricter accountability measures, including the mandatory suspension or termination of funding for projects where agencies provide fraudulent or misleading statements . It also mandates incremental funding tied to metric-based development milestones and requires congressional committees to receive copies of funding agreements upon request. Furthermore, the legislation shifts the TMF's sunset date to after December 31, 2032, providing a clear operational timeline. A significant new section establishes responsibilities for agency and Federal Chief Information Officers (CIOs). Agency CIOs must annually identify and report high-risk legacy information technology systems to the Federal CIO. The Federal CIO is then tasked with compiling a government-wide list of the top 10 highest-risk systems, which must be reported to Congress and the Comptroller General, ensuring greater transparency and strategic focus on critical IT modernization needs.
