This bill, titled the Federal Subaward Reporting System Modernization and Expansion Act, requires a comprehensive review and modernization of the FFATA subaward reporting system. The Inspector General of the General Services Administration must submit a report within 180 days, identifying problems, assessing effectiveness, and recommending improvements for data accuracy, reporting consistency, and public accessibility. Subsequently, the Administrator of General Services must develop and implement an annual plan to update the system, ensuring accurate, timely, and comprehensive information on the first tier of subawards. This plan will include standardized reporting requirements across Federal agencies, provisions to reduce recipient burden, and enhanced enforcement mechanisms. Furthermore, the legislation mandates the expansion of subaward reporting to include the first two tiers of subawards . Federal agencies will be required to collect this expanded data, with the Administrator developing reporting rules and an implementation plan to improve accuracy, standardize requirements, and increase data accessibility for the public and stakeholders.
