Digitization promises to reshape fiscal policy by transforming how governments collect, process, share, and act on information. More and higher-quality information can improve not only policy design for tax and spending, but also systems for their management, including tax administration and compliance, delivery of public services, administration of social programs, public financial management, and more. Countries must chart their own paths to effectively balance the potential benefits against the risks and challenges, including institutional and capacity constraints, privacy concerns, and new avenues for fraud and evasion.
