This bill, titled the "Taxpayer Workforce Modernization Act," requires the Internal Revenue Service (IRS) to establish a fellowship program for qualified data scientists by September 30, 2026. The program's primary objective is to recruit private sector data scientists to collaborate with tax law specialists, addressing the most complex and emerging tax cases. This initiative seeks to enhance tax administration activities, ranging from data acquisition and quality to developing advanced analytics, statistics, and models for improved services and enforcement. The program will staff a minimum of 10 fellows, each serving a 2- to 4-year term, with potential for extensions. These fellows will form a task force responsible for developing data-driven methodologies for audit case selection , educating IRS employees on analytics, and supporting audits through advanced data analysis. The task force will also focus on addressing offshore tax evasion , reviewing existing artificial intelligence use cases, and providing recommendations for improving audit effectiveness and efficiency. Fellows will receive pay not less than the minimum rate for GS-15, and the Commissioner must submit annual reports to Congress detailing the program's effects, return on investment, and any recommendations for changes.
